TERMS OF SERVICE
Terms
Version v1.0 · Effective 2026-04-29 · Last updated 2026-04-29
These terms cover the Tillen mobile app, the websites at tillen.app and members.tillen.app, and the Tillen Sync service. By creating a Tillen account or using the app, you agree to them. If you don't, don't use Tillen.
Who can use Tillen
You need to be 16 or older to create a Tillen account. The app works offline without an account, but features that require a Tillen account (Sync, the members portal) are not available to users under 16.
You agree to keep your account login (your Google account) safe and to let us know promptly if you think someone else has accessed your Tillen account.
Your data is yours
Workouts, templates, custom exercises, body measurements, and every other piece of training data you log in Tillen belong to you. We don't claim any ownership over the content you create.
You can export your data at any time as an encrypted backup file from the app. You can permanently delete your account and all server-side data linked to it from Settings → Account → Delete account in the app, or by emailing [email protected] from the address tied to your account.
What we let you do
Tillen grants you a personal, non-transferable, non-exclusive right to use the app and the service for your own training. The app, the brand, the design, and the source code remain ours. You don't get a license to redistribute, resell, or sublicense any of it.
What you agree not to do
You agree not to:
- Scrape, crawl, or extract data from the service through any means other than the app or the members portal as they're designed to be used.
- Reverse-engineer, decompile, or attempt to extract the source of the app or service except where this right is explicitly granted by applicable law.
- Use Tillen to harm others, distribute malware, or violate the law.
- Attempt to disrupt the service — denial-of-service, abuse of API endpoints, or sustained automated traffic.
- Use someone else's account or share your account with someone else.
- Misrepresent your identity to Tillen.
Service availability
Tillen is offered as-is. The app is offline-first and keeps working even when our servers are not reachable. Tillen Sync and the members portal depend on our servers and on Cloudflare; they may be temporarily unavailable for maintenance or for reasons beyond our control. We make a reasonable effort to keep them up but do not guarantee any specific uptime.
We may update the app and the service to fix bugs, improve features, or address security issues. Some changes may require a newer version of the app. We try not to remove functionality you depend on without notice, but reserve the right to discontinue features that are no longer viable to support.
Termination
You can stop using Tillen at any time and delete your account from Settings → Account → Delete account.
We may suspend or terminate your account if you breach these terms — for example, by attempting to abuse the service or to access another user's data. We will normally notify you first where it's reasonable to do so. Your locally-stored training data on your phone is not affected by an account termination on our side.
No warranty
Tillen is provided without warranty of any kind, express or implied, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the service will be uninterrupted, error-free, or free of harmful components.
Tillen is a tracking and viewing tool. It is not a medical device, not a coach, and not a substitute for professional advice. Listen to your body and consult a qualified professional before starting any new training program.
Limitation of liability
To the maximum extent permitted by applicable law, Tillen will not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of your use of or inability to use the service, including loss of data, revenue, or training records.
Where applicable law does not allow the exclusion or limitation of liability for consequential or incidental damages — including certain mandatory consumer-protection rights you have under EU law — these limitations apply only to the extent permitted. Nothing in these terms limits liability for fraud, gross negligence, or anything that cannot be limited under applicable law.
Privacy
How Tillen collects, uses, and protects your data is described in the Privacy Policy. That document is part of these terms by reference.
Changes to these terms
We may update these terms over time. When we make material changes, we will bump the version number at the top of this page and prompt you to review and accept the new version on next sign-in to the app or the members portal. Continuing to use Tillen after a new version takes effect means you accept the new version. If you don't, the right thing to do is to stop using Tillen and delete your account.
Governing law
These terms are governed by Belgian law, without regard to conflict-of-laws principles. If you are an EU consumer, this does not deprive you of the protection afforded to you by provisions that cannot be derogated from by agreement under the law of your habitual residence.
Disputes arising out of or in connection with these terms or the service will be brought before the competent courts of Belgium, except where mandatory law gives you a right to bring proceedings in the courts of the country where you live.
