2. Accepting these terms

By downloading, installing or using UricLog you agree to these Terms. If you do not agree, please do not use the app. If you use the app on behalf of an organisation, you confirm you are authorised to accept these Terms for it.

3. Licence to use the app

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use UricLog on devices you own or control, for your own non-commercial use, subject to these Terms and to the rules of the app store you downloaded it from.

You may not copy, sell, rent, sublicense, reverse engineer, decompile or attempt to extract the source code of the app, except to the extent that such restriction is prohibited by applicable law.

4. Not a medical device, not medical advice

UricLog is a record-keeping tool. It is not a medical device, it does not diagnose, treat, cure or prevent any condition, and nothing in the app or on this website is medical advice.

Reference ranges, targets, purine estimates and food classifications shown in the app are general information taken from published sources. They may be incomplete, out of date or unsuitable for your situation, and you can edit them. Always consult a qualified healthcare professional about your health, your medication and any treatment decision, and never delay seeking advice because of something you read in the app.

In an emergency, contact your local emergency services.

5. Your records and your responsibilities

6. Optional meal recognition and third-party services

Photo recognition, text meal recognition and voice input are optional. When you use meal recognition, the photo or text you provide is sent through our relay service to an AI model provider solely to produce that one result, as described in the Privacy Policy. Results are estimates generated automatically and may be wrong; review and correct them before saving.

Voice input is handled by the speech service built into your device and is subject to that provider's terms. Your use of Google Play, RevenueCat and any AI model provider is also subject to their own terms.

7. Purchases and subscriptions

Premium features are sold as an auto-renewing subscription or a one-time purchase through Google Play. Prices, billing, free trials, renewals, refunds and cancellation are handled by Google Play under its terms; we do not process or store your payment details.

A subscription renews automatically unless you cancel it in Google Play at least 24 hours before the end of the current period. Cancelling stops future renewals; it does not refund the current period. If you reinstall the app, use "Restore purchases" to recover an active subscription.

We may change or discontinue features, and we may change prices for future billing periods. Changes that affect a subscription you have already paid for will not apply retroactively.

8. Acceptable use

You agree not to:

9. Intellectual property

The app, this website, and their text, design, graphics and code are owned by us or our licensors and are protected by intellectual property laws. These Terms do not transfer any of that ownership to you. The records you create remain yours.

Food composition data is derived from public sources, including the USDA and the ODS-NIH Database for the Purine Content of Foods.

10. Availability and changes to the app

We may release updates, add or remove features, or stop distributing the app. We do not guarantee that any particular feature will remain available, that the app will work on every device, or that it will be free of errors. Some features require an internet connection and depend on third-party services we do not control.

11. Disclaimer of warranties

To the maximum extent permitted by law, the app and this website are provided "as is" and "as available", without warranties of any kind, whether express, implied or statutory, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. Nothing in these Terms excludes warranties that cannot be excluded under the law that applies to you.

12. Limitation of liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, loss of profits, or loss arising from decisions you make on the basis of information recorded or displayed in the app.

Our total liability arising out of or relating to the app or these Terms is limited to the greater of the amount you paid us for the app in the twelve months before the claim, or the minimum amount required by applicable law.

13. Termination

You may stop using the app at any time; uninstalling it ends these Terms. We may suspend or end your access if you materially breach these Terms, in particular section 8. Sections that by their nature should survive termination — including sections 4, 9, 11, 12 and 14 — will continue to apply.

14. Governing law and disputes

These Terms are governed by the laws of the People's Republic of China, without regard to conflict-of-law rules. Before starting formal proceedings, please contact us at the email address above so we can try to resolve the matter. Nothing here removes any mandatory consumer protection you enjoy in your country of residence.

15. Changes to these terms

We may update these Terms from time to time. The current version is always published on this page with a new "last updated" date. If a change is material, we will also describe it in the app's release notes. Continuing to use the app after a change means you accept the updated Terms.

16. General

If any provision of these Terms is found unenforceable, the remaining provisions stay in force. Our failure to enforce a provision is not a waiver of it. These Terms, together with the Privacy Policy, are the entire agreement between you and us about the app.
