Terms of Service

Plain-English summary. Tavy is licensed, not sold. You can use it on your devices. Don't break the law with it. It's not medical care. We made it carefully but offer no guarantees. Refunds are handled by Apple or Google. Slovak law governs disputes.

01The agreement

These Terms of Service (the "Terms") form a binding agreement between you ("you", "user") and j8n, s. r. o., a company registered in the Slovak Republic with its registered office at Bezručova 5, 811 09 Bratislava, Company No. 52258491, VAT No. SK2120970577 ("we", "us", "our"), publisher of the Tavy mobile application ("Tavy", the "App") and the website at tavy.sk (the "Site"). By downloading, installing, or using Tavy, you agree to these Terms. If you do not agree, do not use Tavy.

02The service

Tavy is a personal productivity and focus tool — what we call an "ADHD Start Button." It offers calming guided flows ("Reset"), AI-assisted task breakdown ("Brain Sort"), a visual countdown timer, voice-and-text capture, and gentle habit tracking ("Soft Habits"). Tavy is intended as a general-purpose self-help tool. It is not a medical device, therapy, diagnosis, or treatment. See § 08.

03Eligibility

You must be at least 16 years old to use Tavy. By using Tavy you confirm that you meet this age requirement and that you have the legal capacity to enter into this agreement. If you are using Tavy in a country whose minimum digital-consent age is higher, you must meet that age.

04Licence to use Tavy

Subject to your compliance with these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable licence to:

Install and use Tavy on any device that you own or control, in line with the Apple App Store and Google Play store terms;
Use Tavy for your personal, non-commercial purposes.

You may not:

copy, modify, reverse engineer, decompile, disassemble, or attempt to derive the source code of Tavy, except to the extent applicable law expressly permits;
rent, lease, lend, sell, sublicense, distribute, or otherwise transfer Tavy or your access to it;
remove or alter any copyright, trademark, or other proprietary notices;
use Tavy to build a competing product or to scrape AI responses for training datasets;
use Tavy in any way that infringes any third-party right or applicable law.

All title, ownership and intellectual property rights in Tavy remain with us and our licensors. No rights are granted by implication.

05Purchase & refunds

One-time purchase

Tavy uses a one-time in-app purchase ("Lifetime Pro") to unlock premium features. There is no recurring subscription. The price is shown in the App Store or Google Play at the time of purchase (USD 24.99 at launch, before any regional adjustments by the store) and is processed by the respective platform.

Free features

Reset and the Visual Timer remain available without any purchase. You can use Tavy meaningfully without ever paying.

Refunds

Refunds are processed exclusively by Apple or Google according to their published policies — we do not directly charge your card and we cannot directly refund it. Useful links:

Apple: reportaproblem.apple.com
Google Play: Play Store → profile → Payments & subscriptions → Budget & history

EU consumers retain their statutory right of withdrawal under Directive 2011/83/EU, subject to the digital-content exceptions (Art. 16(m)). By starting to use the premium features immediately on purchase, you acknowledge that the right of withdrawal may be lost where applicable.

06Your content

Anything you type, dictate, capture or record in Tavy ("Your Content") is and remains yours. We do not claim ownership and we do not use Your Content to train AI models.

To run the service, you grant us a limited, worldwide, royalty-free, non-exclusive licence to process Your Content solely for the purpose of providing Tavy to you (for example: storing tasks, returning Brain Sort results, syncing across your devices if you opt in). This licence ends when you delete the content or uninstall the app, except where we are legally required to retain it.

07Acceptable use

You agree not to use Tavy to:

break any applicable law or third-party right;
upload or generate content that is illegal, harassing, hateful, sexually explicit involving minors, or otherwise abusive;
attempt to bypass purchase verification, security, or rate limits;
probe, scan, overload, or otherwise interfere with the service or the AI provider;
impersonate any person or misrepresent your affiliation with anyone.

We may suspend or terminate access without notice if you breach this section.

08Medical disclaimer

Tavy is not a medical device. It does not diagnose, treat, cure, or prevent any disease or condition, including but not limited to Attention-Deficit/Hyperactivity Disorder. Content shown in the app — including reset flows and AI-generated suggestions — is for general informational and motivational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment.

Always seek the advice of a qualified healthcare professional with any questions you may have regarding a medical condition. Never disregard professional medical advice or delay seeking it because of something you read or saw in Tavy. If you are experiencing a mental-health crisis, please contact local emergency services or a recognised helpline.

09Warranty disclaimer

Tavy is provided "as is" and "as available", without warranty of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that Tavy will be uninterrupted, secure, error-free, or that AI outputs will be accurate, complete, or useful for any specific situation.

This section does not exclude any rights you may have as a consumer under mandatory provisions of Slovak or EU law.

10Limitation of liability

To the maximum extent permitted by law, in no event shall j8n, s. r. o., its directors, employees, contractors, or licensors be liable for any indirect, incidental, special, consequential, or punitive damages, including lost profits, lost data, or lost goodwill, arising out of or in connection with your use of Tavy.

Our total aggregate liability for any and all claims related to Tavy shall not exceed the greater of (a) the amount you paid us for Tavy in the twelve months before the event giving rise to the claim, or (b) USD 30.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be excluded under applicable law.

11Termination

You may stop using Tavy at any time by deleting the app. We may suspend or terminate your access if you breach these Terms or if continued operation becomes impractical (for example because a third-party API is discontinued). Sections that by their nature should survive termination (intellectual property, disclaimers, liability, governing law) shall survive.

12Governing law & disputes

These Terms are governed by the laws of the Slovak Republic, without regard to its conflict-of-laws rules. Subject to your mandatory consumer rights, the courts of Bratislava, Slovak Republic shall have exclusive jurisdiction over any dispute arising from or in connection with these Terms.

EU consumers may also bring disputes before the European Commission's Online Dispute Resolution platform, although we will first try to resolve any matter directly with you.

13Changes to these Terms

We may update these Terms from time to time. Material changes will be announced inside the app and on the Site at least 14 days before they take effect. If you continue to use Tavy after the effective date of an update, you accept the updated Terms. If you do not agree, you should stop using Tavy.

The Apple Standard EULA additionally applies to App Store purchases. Where its terms conflict with these Terms, the more favourable provision to the consumer shall prevail.
