Terms of Service

1. Who we are

These Terms form a binding agreement between you ("you", "the user") and the operator of the Tea Cellar app (the "Service"), referred to in these Terms as "we", "us", or "the provider":

• Filip Bury
• Světova 523/1, 180 00 Praha 8 – Libeň, Czech Republic
• IČO: 06363342
• Email: f.bury@email.cz

By creating an account or otherwise using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

2. Licence to use the app

Subject to your compliance with these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and run the Tea Cellar mobile app on devices you own or control, and to access the Service for your own personal, non-commercial use.

This licence does not transfer any ownership. All intellectual property rights in the Service, the app, its code, its design, and its trademarks remain with us or our licensors. You may not:

• copy, modify, translate, or create derivative works of the app;
• reverse-engineer, decompile, or disassemble the app, except to the limited extent that applicable law (including Article 6 of Directive 2009/24/EC) prohibits this restriction;
• remove or alter any proprietary notices or marks;
• rent, lease, sell, sublicense, or otherwise transfer the app or any rights in it.

The licence terminates automatically if you breach these Terms or delete your account. On termination you must stop using the app and delete it from your devices.

3. The service

Tea Cellar is a personal tea inventory and brewing journal. It lets you track teas you own, log brewing sessions, receive low-stock reminders, and use AI-assisted extraction to read data from tea labels. The Service is offered "as is" and is intended for personal, non-commercial use.

4. Your account

• You must provide a valid email address and a strong password. You are responsible for keeping your credentials confidential.
• You must be at least 16 years old to create an account and use the Service. The Service is intended for an adult and teenage audience interested in tea. It is not directed at children, we do not provide features for parental consent, and we do not knowingly collect personal data from anyone under 16. If we learn that an account belongs to a user under 16, we will close it and delete the associated data. The 16-year floor is set above the Czech implementation of Art. 8 GDPR (15 years) to keep a single rule across the EEA.
• You are responsible for all activity that happens under your account. If you suspect unauthorised access, sign out of all sessions from Settings or contact support.

5. Acceptable use

You agree not to:

• Upload content that is illegal, abusive, infringes on others' rights, or depicts minors in sexual or exploitative contexts. We run automated moderation on label images and will terminate accounts that attempt such uploads.
• Attempt to reverse-engineer, scrape, or circumvent rate limits or authentication.
• Use the Service to transmit spam, malware, or to impersonate another person.
• Resell, sublicense, or commercially redistribute the Service without our written permission.
• Use automated systems (bots, scripts) to interact with the Service at a volume that degrades the experience for others.

6. AI-generated content

The Service uses OpenAI large-language and vision models to extract structured metadata from label images, suggest brewing parameters, and assist with data entry (collectively, "AI output"). AI output is informational only, is produced by a third-party model we do not control, and may be inaccurate, incomplete, biased, outdated, or entirely fabricated.

You acknowledge and agree that:

• AI output is not professional advice of any kind — not medical, not nutritional, not legal, not financial, not allergy-related.
• You must independently verify any AI-suggested value before acting on it, particularly for decisions that affect health or safety (caffeine or theanine content, allergen warnings, brewing temperature and time for infants, pregnancy, medical conditions, or medication interactions).
• We make no warranty as to the accuracy, completeness, reliability, or fitness for purpose of any AI output, and to the maximum extent permitted by law we disclaim all liability for decisions you or third parties take based on AI output.
• AI output may occasionally include text originating from third-party sources. You should treat it as drafts to be reviewed, not as verified facts.

7. Your content

You retain full ownership of the data you add to the Service (teas, brewing sessions, notes, images). By uploading content, you grant us a limited, non-exclusive, royalty-free licence to store and process it for the sole purpose of providing the Service to you. We do not use your content to train third-party AI models and do not grant the third-party AI processor any retention or training rights over it.

You represent and warrant that you own or have the necessary rights to the content you upload, and that your upload does not violate the rights of any third party or any applicable law.

8. Account termination

You may delete your account at any time from Settings → Delete Account. Deletion is permanent and erases all your data as described in the Privacy Policy.

We may suspend or terminate your account if you materially breach these Terms, engage in fraud or abuse, or create a security or legal risk for us, our users, or our processors. We will give reasonable prior notice where feasible, except when immediate action is necessary to protect users or the Service. On termination, the licence in section 2 ends and the data-deletion timelines in the Privacy Policy apply.

9. Service availability

We aim for high availability but do not guarantee uninterrupted service. We may perform maintenance, roll out updates, or temporarily restrict features without prior notice. Third-party dependencies (email delivery, AI providers, hosting) may occasionally fail in ways beyond our control.

10. Disclaimers

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied, including without limitation warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. Brewing guidance and health-related commentary, if any, are not medical advice.

11. Limitation of liability

To the maximum extent permitted by applicable law, we are not liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, or goodwill, arising out of or related to your use of the Service, including but not limited to losses caused by reliance on AI output. Our total cumulative liability for any claim will not exceed the greater of (a) the amount you paid us for the Service in the twelve months preceding the claim, or (b) EUR 50.

Nothing in these Terms excludes or limits any liability that cannot legally be excluded or limited, including liability for gross negligence, wilful misconduct, death or personal injury caused by negligence, or your statutory consumer rights.

12. Changes to the Terms

We may update these Terms from time to time. We will update the effective date and, for material changes, notify signed-in users in the app. Continued use after the effective date constitutes acceptance. If you do not accept the updated Terms, delete your account before the change takes effect.

13. Governing law and jurisdiction

These Terms are governed by the laws of the Czech Republic, without regard to conflict-of-law principles. The UN Convention on Contracts for the International Sale of Goods does not apply.

Exclusive jurisdiction for any dispute arising out of or in connection with these Terms lies with the competent courts of the Czech Republic, and specifically the court having jurisdiction over the seat of the provider, unless mandatory consumer-protection law in your country of residence grants you a different forum that cannot be waived.

14. Consumer rights and out-of-court dispute resolution

If you are a consumer (spotřebitel) under Czech law, these Terms do not limit any mandatory rights you have under Act No. 89/2012 Coll. (the Civil Code) or Act No. 634/1992 Coll. (the Consumer Protection Act), including the right to withdraw from a contract concluded by distance means where applicable.

Under § 20d of the Consumer Protection Act, consumers have the right to out-of-court resolution of disputes arising from these Terms. The competent body for this Service is:

• Česká obchodní inspekce (Czech Trade Inspection Authority)
• Ústřední inspektorát – oddělení ADR
• Gorazdova 1969/24, 120 00 Praha 2 – Nové Město, Czech Republic
• Website: adr.coi.cz
• Email: adr@coi.cz

EU consumers may also use the European Commission's Online Dispute Resolution platform (ec.europa.eu/consumers/odr). Use of these bodies is voluntary; we would appreciate the chance to address your concern directly first — please contact us at the email above.

15. Apple App Store — additional terms

The following additional terms apply only if you obtained the Tea Cellar app from the Apple App Store. They reflect the minimum provisions that a Custom End User Licence Agreement must contain under Schedule 1 of the Apple Developer Program Licence Agreement. In the event of any conflict between these Apple-specific provisions and the rest of these Terms, the Apple-specific provisions prevail, but only to the extent of the conflict and only with respect to Apple.

• Parties. These Terms are concluded between you and us. Apple Inc. is not a party to these Terms and is not responsible for the app or its content.
• Scope of licence. The licence granted in section 2 is further limited to a non-transferable licence to use the app on any Apple-branded device that you own or control, and as permitted by the App Store Usage Rules set out in Apple's Media Services Terms and Conditions.
• Maintenance and support. We are solely responsible for providing any maintenance or support for the app. Apple has no obligation to provide any maintenance or support in relation to the app.
• Warranty. We are solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the app to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the app to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the app, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be our sole responsibility.
• Product claims. We, not Apple, are responsible for addressing any claims by you or any third party relating to the app or your possession and/or use of the app, including (i) product liability claims; (ii) any claim that the app fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer-protection, privacy, or similar legislation.
• Intellectual property claims. In the event of any third-party claim that the app or your possession and use of the app infringes that third party's intellectual property rights, we, not Apple, will be solely responsible for the investigation, defence, settlement, and discharge of any such intellectual-property infringement claim.
• Legal compliance. You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a "terrorist supporting" country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
• Third-party beneficiary. You and we acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
