Terms of Use

01Agreement

These Terms of Use (the “Terms”) govern your access to and use of the QRONOS website at qronos.ai (the “Website”) and the QRONOS mobile application (the “App”). The Website and the App are together the “Service”.

The Service is operated by Qronos AI Pte. Ltd. (UEN 202636102Z), a company incorporated in Singapore with its registered office at 2 Venture Drive, #19-18, Vision Exchange, Singapore 608526 (the “Company”, “we”, “us”, “our”).

By creating an account, purchasing credits, or otherwise using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree with our policies and practices, your choice is not to interact with the Service.

These Terms are written in English. Any translation is provided for convenience only. Where a translation conflicts with the English version, the English version governs, except where the law of your country requires otherwise.

02Where the Service is offered

The Service is offered only in the territories where the App is listed on the Apple App Store or Google Play. The Service is not offered in the European Economic Area, the United Kingdom, mainland China, Saudi Arabia, the United Arab Emirates, Türkiye, Brazil or Vietnam. We do not target, market to, or solicit users in those territories. This list may change; the territories in which the App is listed on the App Store and Google Play are definitive.

By using the Service you represent that you are not accessing it from a territory in which it is not offered. We may restrict or withdraw availability in any territory at any time.

You must not use a proxy, VPN, relay, storefront change or similar means to misrepresent the country you are actually in, in order to obtain access, features, pricing or eligibility that are not available in your actual location.

03What Qronos is

Qronos is a decision-support service. You submit one question about a decision you are weighing, and the Service returns a structured written analysis.

The analysis is produced in two stages. First, a deterministic calculation builds a structured model from the exact moment your question is submitted, using your local time and time zone. Second, a large language model interprets that model against our proprietary analytical framework and expresses the result in plain language.

Qronos does not hold a conversation. Each reading is a single, standalone analysis, and the Service does not monitor your situation or maintain an ongoing advisory relationship with you. We may send you service messages about a reading you have already received — most often that its review date has arrived. Those are reminders about your own reading, not continuing advice.

04Method, not faculty

Qronos does not claim, and does not rely on, occult, supernatural, psychic or paranormal powers or abilities.

Qronos applies a documented analytical method: a deterministic calculation derived from the moment a question is asked, interpreted against a structured framework by a language model.

A reading may state directly what the analysis indicates about how a matter is likely to go — that is the point of it, and we do not soften a reading to make it more comfortable. Those statements are inferences drawn from a method with known limitations, in the way an analyst draws a conclusion from a model. They are not claims of foreknowledge, they are not certainties, and no outcome is guaranteed.

Readings are provided for reference. We make no claim as to the accuracy, reliability or efficacy of the Service, and the decision you take and its consequences are yours.

05Not professional advice

Readings are made available solely for general information purposes. They are not professional, medical, legal, financial, tax, investment, insurance or psychological advice, and they must not be treated as a substitute for advice from a qualified professional.

We are not licensed or registered as a financial adviser, investment adviser, medical practitioner, legal practitioner or counsellor in any jurisdiction, and nothing in the Service creates any advisory, fiduciary, therapeutic or professional relationship between you and us.

Where a question touches a health, legal, financial or psychological matter, the reading may include a pointer to seek qualified professional advice. That pointer does not change the nature of the reading, and its absence does not imply that professional advice is unnecessary.

You are responsible for your own decisions. Any reliance you place on a reading is strictly at your own risk.

06Eligibility

The Service is intended for people aged 18 or over. By creating an account you confirm that you are at least 18 years old. We collect your year of birth in order to verify this.

If we become aware that an account belongs to a person under 18, we will suspend it and delete the associated personal data.

07Your account

You register using Sign in with Apple or a Google account. You choose a nickname, and you provide your gender and your year of birth. Your year of birth is required so that we can confirm you are 18 or over. Your gender is used by the analytical framework, which reads certain signals differently depending on it.

Your month, day and hour of birth are optional. Providing them produces a sharper, more personalised reading; declining does not prevent you from using the Service. We do not ask for your legal name, your telephone number or your postal address.

You are responsible for activity that occurs under your account. You must not share your account, sell it, or transfer it to anyone else, and you must not hold more than one account.

You may delete your account at any time using the Delete my account control in the App on either iOS or Android, or from the web at qronos.ai/delete-account. Deletion is permanent. Please read section 8 before deleting an account that holds unused credits.

08Credits and purchases

Readings are paid for with credits. One credit is required for one reading.

Credits are purchased through Apple's In-App Purchase or Google Play Billing. Apple and Google are the merchant of record for every purchase. Your purchase is a transaction between you and Apple or Google, governed by their terms. These Terms govern the Service, not the sale.

• Credits do not expire. They remain in your account for as long as your account is open.
• Credits have no cash value, are not a stored-value instrument, are not redeemable for money, and cannot be transferred, sold, gifted or combined between accounts.
• An opening credit is issued once per person on registration, not per account, so that your first reading is included. It is non-transferable, has no cash value, and may be withdrawn or revoked where we detect more than one account held by the same person. We may vary or withdraw this offer at any time; doing so does not affect a credit already issued to you.
• We may issue promotional credits from time to time, subject to the conditions we state when we offer them. Promotional credits are non-transferable, have no cash value, and may be revoked where the stated conditions were not met or were manipulated. We may end any promotion at any time.
• One credit answers one question. The Service is built to take one question per submission. If a submission contains more than one distinct question and the Service answers more than one, each answered question consumes a credit, and we will tell you when that has happened. Where we decline a submission because it contains more than one question, no credit is consumed.
• If your account is closed, whether by you or by us, any unused credits are forfeited. We will tell you this on screen before you confirm deletion.

09Refunds, clawback and consumption data

We cannot issue monetary refunds. Because Apple and Google are the merchant of record, refund requests must be made to them, under their policies. Nothing in these Terms affects your right to request a refund from Apple or Google.

Consumption data. When you request a refund on a credit purchase, Apple or Google may ask us for information about that purchase in order to decide it, including whether a reading was delivered, how many credits have been used, how long you have held your account, and your prior purchase and refund history with the Service. You consent to us providing that information to Apple or Google for the purpose of evaluating your refund request.

Clawback. Where a purchase is refunded, charged back or otherwise reversed, the credits issued for that purchase are revoked. If those credits have already been used, your balance will become negative, and the negative balance must be cleared before you can use the Service again.

10Availability and delivery

The Service is provided on a best-effort basis. We do not offer or warrant any service level. Response times vary with system load and with the availability of the third-party providers we depend on, and a reading may be delayed or may fail to be delivered.

A credit is consumed when a reading is delivered to you. If no reading is delivered, no credit is consumed.

If a credit is consumed but no reading reaches you, tell us at hello@qronos.ai. We will investigate, and where we confirm the failure we will restore the credit to your balance. Restoration of a credit is your sole and exclusive remedy from us for a failed or delayed reading. As stated above, this does not affect your right to request a refund from Apple or Google.

The reading depends on your device's clock and time zone. The analysis is built from the moment you ask, read against your local time. We take the moment itself from our own servers, but the time zone we apply is the one your device reports. If your device reports a time zone that is not where you actually are — because you have set it manually, or are using a VPN or a similar tool — the reading will be built on the wrong local time. A reading affected in that way has still been delivered, and is not a delivery failure.

You may ask in any language; readings are delivered in English or Chinese only. Where you write in another language, we translate your question internally before analysing it, and a translation may not carry your exact meaning. A reading delivered in English or Chinese has been delivered, and dissatisfaction with how a translation carried your question is not a delivery failure. If precision matters to you, ask in English or Chinese.

We are not liable for any failure or delay caused by events outside our reasonable control, including failures of network, hosting, payment or artificial-intelligence infrastructure operated by third parties.

11Acceptable use

You must not use the Service:

• to seek guidance relating to self-harm, suicide, or harm to any other person;
• in relation to the safety, exploitation or abuse of a child;
• to plan, assist or carry out any unlawful activity;
• in place of emergency medical, psychological or crisis care;
• for gambling, wagering, lottery selection or any similar activity;
• to ask about elections, candidates, or party-political outcomes;
• to harass, defame, deceive, impersonate, or infringe the rights of any person;
• to build, train, benchmark or evaluate a competing product or model, or to extract, reverse-engineer or reconstruct our framework, prompts, rules or methodology;
• by automated means, or to submit bulk or artificial requests, or to stress, probe or scan our systems;
• to falsify the time of asking, hold multiple accounts, or exploit the credit, promotional or refund mechanisms.

You must not attempt to circumvent, disable or defeat any filtering, safety or usage restriction — including by rephrasing, obfuscation, translation, encoding, splitting a prohibited request across several questions, or instructing the Service to disregard its constraints. An attempt to do so is itself a breach of these Terms.

We apply filtering and safety measures, but they are not perfect. We do not warrant that any particular question, content or use will be detected, blocked or refused.

12Safety

Qronos is not an emergency service. It cannot summon help, it is not monitored in real time, and it must not be relied on in a crisis.

If you or anyone else is in immediate danger, or is experiencing a medical, psychological or safety emergency, contact your local emergency number or a crisis helpline now. You can find a helpline at findahelpline.com.

We aim to identify questions that indicate crisis or risk of harm and to respond by pointing to findahelpline.com rather than by producing an analysis. As stated in section 11, we do not warrant that any particular question will be detected, and you must not rely on the Service to recognise a crisis.

Where the Service declines to answer a question, no credit is consumed and no liability arises from the refusal.

13Responses given in error

Where the Service produces a response to a question that these Terms prohibit, that response is given in error and is not authorised by us. It does not constitute a representation that the question was permitted, a waiver of section 11, or advice of any kind, and it remains subject to every disclaimer and limitation in these Terms.

14Questions about other people

You may ask about a decision that involves another person. When you do, you are providing us with information about them.

You represent and warrant that you have a lawful basis to provide any information about another person that you include in a question, and that doing so does not breach any duty of confidence, privacy law, or other obligation you owe them.

We ask you not to include full names, company names or other identifying details. They are not needed for the analysis, and questions written about the decision rather than about the person produce better readings.

15Your content

You keep ownership of the questions you submit. You grant us a worldwide, non-exclusive, royalty-free licence to host, store, process and analyse your questions for the purpose of operating, securing and improving the Service, as described in our Privacy Policy.

You may use the readings you receive for your own purposes, including commercially. Readings are generated in part by an artificial-intelligence system, and their copyright status may differ between jurisdictions; we make no representation that a reading attracts copyright protection or that it is unique to you. You must not present a reading as your own original analysis, or use our name or branding to imply endorsement or affiliation.

Feedback. If you send us ideas, suggestions or feedback about the Service — including a report that a reading misread your situation, which section 17 invites — you agree that we may use it without restriction, without any obligation of confidence, and without payment to you. This does not apply to the questions you submit, which are covered by the paragraph above and by the Privacy Policy.

Sharing a reading is your decision and your responsibility. The Service may offer ways to share a reading. If you share one — privately or publicly — you decide who sees it, and you accept that we cannot recall it afterwards. Where a reading concerns another person, sharing it may reveal something about them, and you are responsible for that. We are not responsible for how any recipient interprets, relies on, or further shares a reading you chose to send them, and section 23 applies to any claim arising from it.

16Publication consent

We sometimes publish anonymised readings as examples of what the Service produces. We do this only where you have opted in, in your account settings.

Opting in does not publish anything by itself. It makes your readings eligible, and before we publish any individual reading we will contact you and give you the opportunity to decline that one. We publish the reading only — never your question — and we remove names of people and companies before publishing.

Where you opt in, you grant us a worldwide, non-exclusive, royalty-free licence to reproduce, display and distribute a reading we have notified you about, in any medium.

You may withdraw consent at any time in your account settings, or by writing to privacy@qronos.ai. Withdrawal applies going forward. We will remove the material from surfaces we control, but we cannot recall copies already distributed or captured by others.

You warrant that a reading you consent to publish does not contain anything defamatory, confidential, or infringing of another person's rights.

17AI disclosure and limitations

You are interacting with an artificial-intelligence system. The chart underlying a reading is calculated deterministically; the interpretation is generated by a large language model.

Output generated by an AI system is probabilistic. It may contain errors, inaccuracies, omissions or biases, and it may be internally inconsistent or wrong. We do not guarantee the accuracy, reliability, availability, suitability or completeness of any reading. You should evaluate a reading against your own judgment and, where the matter warrants it, against professional advice, before acting on it.

Stated limitations of the framework. Our framework was developed against a body of recorded cases carrying particular assumptions. Analysis of some question types — including relationships and circumstances that fall outside those assumptions — may be less reliable than analysis of the cases the framework was built on. We treat this as a known limitation of the instrument, and we are actively developing it.

One instance is worth stating plainly. Because the framework reads certain signals differently by gender, a question about a relationship between people of the same gender may be read against assumptions that do not fit it. We instruct the framework to suppress gender-derived signals where the question does not make the relationship explicit, so that it does not draw a conclusion from an assumption you have not made. That instruction reduces the problem but does not eliminate it. If a reading appears to have misread your situation in this way, tell us at hello@qronos.ai — it is the kind of report that improves the framework.

The Service holds no memory of your previous questions beyond what is described in the Privacy Policy, and it cannot verify anything you tell it.

18Suspension and termination

We may suspend your access immediately, and freeze any credits in your account, while we investigate a reasonable suspicion of:

• repeated refund requests following delivery of readings;
• use of more than one account by the same person, including where indicated by device signals;
• attempts to circumvent filtering, safety or usage restrictions;
• any other breach of section 11;
• fraudulent, unauthorised or exploitative acquisition or use of credits.

We will make reasonable efforts to notify you of a suspension, but we are not obliged to give advance notice where fraud or abuse is suspected. Where an investigation clears you, we will restore access and unfreeze your credits.

We may terminate your account for a material or repeated breach of these Terms. On termination, unused credits are forfeited. You may close your account at any time.

Sections 5, 13, 15, 19, 21, 22, 23, 25 and 27 survive termination.

19Intellectual property

© 2026 Qronos AI Pte. Ltd. All rights reserved.

The QRONOS name, logo, website, app, framework, rules, prompts, analytical methodology, output schema and all associated content are owned by or licensed to the Company and are protected by intellectual property laws. Nothing in these Terms transfers any of those rights to you.

If you believe material on the Service infringes your rights, write to legal@qronos.ai identifying the material, your rights in it, and your contact details.

20Software licence

This section is the end-user licence agreement for the App. It applies in addition to the rest of these Terms.

• Parties. This licence is concluded between you and the Company only, and not with Apple Inc. or Google LLC. The Company, not Apple and not Google, is solely responsible for the App and its content.
• Scope. We grant you a limited, non-transferable licence to use the App on any Apple-branded product that you own or control, and as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions — except that the App may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing. The same limited, non-transferable licence applies on any Android device that you own or control, as permitted by the Google Play Terms of Service. You may not distribute, sublicense, rent, lease, sell, reverse-engineer, decompile or disassemble the App.
• Maintenance and support. The Company is solely responsible for providing any maintenance and support for the App. Apple and Google have no obligation to provide any maintenance or support.
• Warranty. The Company is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you where a purchase price was paid. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App.
• Product claims. The Company, not Apple and not Google, is responsible for addressing any claim by you or any third party relating to the App or your possession or use of it, including product liability claims, any claim that the App fails to conform to a legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.
• Intellectual property. If a third party claims that the App infringes its intellectual property rights, the Company, not Apple and not Google, is solely responsible for the investigation, defence, settlement and discharge of that claim.
• Legal compliance. You represent and warrant that you are not located in a country subject to a United States Government embargo or designated by the United States Government as a “terrorist supporting” country, and that you are not listed on any United States Government list of prohibited or restricted parties.
• Contact. Questions, complaints or claims relating to the App should be directed to Qronos AI Pte. Ltd., 2 Venture Drive, #19-18, Vision Exchange, Singapore 608526 · hello@qronos.ai · +1 628 600 9658.
• Third-party terms. You must comply with any applicable third-party terms of agreement when using the App, including the App Store Terms of Service and the Google Play Terms of Service.
• Third-party beneficiary. You acknowledge and agree that Apple Inc. and Apple's subsidiaries are third-party beneficiaries of this licence, and that upon your acceptance of these Terms, Apple will have the right — and will be deemed to have accepted the right — to enforce this licence against you as a third-party beneficiary. The same applies to Google LLC in respect of the App distributed through Google Play.

21Disclaimer of warranties

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, YOU EXPRESSLY UNDERSTAND AND AGREE THAT YOUR USE OF THE SERVICE, AND OF ALL READINGS AND OTHER CONTENT OBTAINED THROUGH IT, IS AT YOUR OWN RISK. THE SERVICE IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, OR NON-INFRINGEMENT. NEITHER THE COMPANY NOR ANYONE ASSOCIATED WITH IT WARRANTS THAT THE SERVICE WILL BE ACCURATE, RELIABLE, COMPLETE, ERROR-FREE OR UNINTERRUPTED, THAT DEFECTS WILL BE CORRECTED, OR THAT THE SERVICE WILL MEET YOUR NEEDS OR EXPECTATIONS.

Some jurisdictions do not allow the exclusion of implied warranties, so some of the above may not apply to you. In those jurisdictions our liability is limited to the greatest extent permitted by law.

22Limitation of liability

UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER IN CONTRACT, TORT OR OTHERWISE, SHALL THE COMPANY BE LIABLE TO YOU OR TO ANY THIRD PARTY FOR (A) ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, LOST OPPORTUNITIES, LOST SALES OR BUSINESS, LOST DATA, OR ANY LOSS ARISING FROM A DECISION TAKEN OR NOT TAKEN; OR (B) ANY DIRECT DAMAGES, COSTS, LOSSES OR LIABILITIES, INCLUDING LEGAL FEES, IN EXCESS OF THE GREATER OF (I) THE FEES ACTUALLY PAID BY YOU FOR CREDITS IN THE TWO (2) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, AND (II) ONE HUNDRED UNITED STATES DOLLARS (US$100).

The provisions of this section allocate the risks under these Terms between the parties, and the parties have relied on these limitations in determining whether to enter into these Terms.

Nothing in these Terms excludes or limits our liability for fraud, for death or personal injury caused by our negligence, or for any other liability that cannot lawfully be excluded or limited. Some jurisdictions do not allow the limitation of liability for incidental or consequential damages, which means some of the above may not apply to you. In those jurisdictions our liability is limited to the greatest extent permitted by law.

23Indemnity

You agree to indemnify and hold harmless the Company and its officers, employees and agents from any claim, damage, loss, liability or expense, including reasonable legal fees, arising from your breach of these Terms, your misuse of the Service, information you provide about another person, or any third party's reliance on a reading you shared with them.

24Local law

Some jurisdictions regulate or restrict services of this nature. The Service is offered only where it may lawfully be offered. Where the law of your jurisdiction imposes requirements on such services, those requirements apply and prevail over any inconsistent term in these Terms, and nothing here limits any right you have under the mandatory consumer-protection law of your country of residence.

You are responsible for complying with the laws that apply to you where you use the Service.

25Governing law and disputes

These Terms, and any dispute arising out of or in connection with them or with the Service (including non-contractual disputes), are governed by the laws of the Republic of Singapore, without regard to its conflict-of-laws rules.

25.1 Talk to us first. Before either of us starts a formal proceeding, we agree to try to resolve the matter informally. The party raising the claim must send written notice to the other describing the claim and the relief sought — to legal@qronos.ai if the claim is against us. Within 60 days of that notice, we will meet by telephone or video conference in good faith to try to resolve it. Completing this step is a precondition to starting arbitration. Time limits and filing deadlines are paused while this step runs.

25.2 Arbitration. If the informal step does not resolve the matter, any dispute shall be referred to and finally resolved by arbitration administered by the Singapore International Arbitration Centre (“SIAC”) in accordance with its rules in force at the time. The seat of arbitration is Singapore, the tribunal consists of one arbitrator, and the language is English. The arbitrator may award any relief a court could award to you individually.

Exceptions. Either of us may (a) bring a claim in a small-claims or equivalent court in the place where you live, provided it stays in that court and proceeds on an individual basis; and (b) seek injunctive relief in court for infringement or misuse of intellectual property.

Costs. Where your claim is for less than US$10,000 and is not frivolous, we will pay the SIAC filing and administrative fees.

25.3 No class actions. YOU AND THE COMPANY AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE OR REPRESENTATIVE PROCEEDING. CLAIMS OF MORE THAN ONE USER MAY NOT BE ARBITRATED OR LITIGATED JOINTLY OR CONSOLIDATED. YOU AND THE COMPANY WAIVE ANY RIGHT TO A JURY TRIAL. If this waiver is held unenforceable as to a particular claim, that claim is severed from the arbitration and heard in the courts of Singapore; the rest of this section continues to apply.

25.4 Batched arbitrations. If 100 or more similar arbitration demands are filed against us within a 30-day period by or with the assistance of the same law firm or organisation, the arbitration provider shall group them into batches of no more than 100 demands, and resolve each batch as a single arbitration with one set of fees and one arbitrator. You agree to cooperate in good faith with that process.

25.5 Opting out. You may opt out of this section 25. To do so, email legal@qronos.ai within 30 days of first accepting these Terms, with your account email address and a clear statement that you are opting out of the arbitration agreement. Opting out affects nothing else in these Terms, and we will not treat it as a reason to restrict your account. If you opt out, disputes are subject to the exclusive jurisdiction of the courts of Singapore.

25.6 Survival and changes. This section survives termination of your account. If we materially change this section, the change will not apply to any claim you had already notified to us.

26Changes to these Terms

We may update these Terms as the Service develops and as our business and operations require. The “Last updated” date at the top reflects the most recent change.

Where a change is material, we will give notice in the App or by email before it takes effect, state the date it takes effect, and ask you to accept the updated Terms. Continued use of the Service after a change takes effect constitutes acceptance of it. A material change does not apply retroactively to a dispute you had already notified to us.

27General

If any provision of these Terms is held invalid or unenforceable, it is limited or removed to the minimum extent necessary and the remaining provisions continue in full force.

Our failure to enforce a provision is not a waiver of it. You may not assign these Terms; we may assign them in connection with a merger, acquisition or sale of assets. These Terms, together with the Privacy Policy, are the entire agreement between you and us about the Service.

Notices. We give you notice by message in the App, or by email to the address associated with the Apple or Google account you registered with. It is your responsibility to keep that account reachable. You give us notice at the address in section 28.

Changes to the Service. We may add, change, suspend or remove features of the Service, and may stop offering it entirely. We will give reasonable notice of a change that materially reduces what the Service does. Credits you have already bought are not affected by a feature change; if we stop offering the Service altogether, we will say so in that notice and explain how any unused credits will be handled.

Third-party rights. Apart from Apple and Google under section 20, no person other than you and the Company has any right to enforce any term of these Terms.

Links to other sites. The Service may link to websites we do not operate — for example a crisis helpline directory. Those links are for your convenience only. We do not endorse those sites, we do not control their content, and we are not responsible for them.
