We don't sell your data, we don't run ads, and we don't share your information with anyone.
When you create an account, we store your email address and a hashed password (we never see your actual password). If you sign in with Google, we receive your email address from Google — nothing else.
When you use the app, we store the workout data you enter: weights, effort ratings, calories, release ratings, reviews, and your library preferences. We also store your display name(s) and settings like kg/lbs preference.
We don't collect analytics, we don't use cookies for tracking, and we don't build profiles about you.
Your data is stored in Supabase, hosted on AWS infrastructure in the EU. Your data is protected by row-level security — you can only access your own data. A copy is also kept in your browser's local storage so the app works offline.
Only you. The app developer (Dan) has access to the database for maintenance and bug fixing, but has no reason or interest in looking at individual workout data.
Access — everything is visible in the app.
Delete — you can permanently delete your account and all data from the Settings page. Once deleted, it's gone — we keep nothing.
Export — if you'd like a copy of your data, get in touch and we'll provide it.
Supabase hosts our database and authentication (privacy policy). Netlify hosts the app (privacy policy). Google — only if you choose to sign in with Google. We don't use any other third-party services or trackers.
LM Tracker is free. No ads, no subscriptions, no premium tiers. If you find it useful, consider donating to UNICEF — but that's entirely optional.
You're responsible for keeping your login details secure. You can delete your account at any time from Settings.
LM Tracker is provided "as is". It's a side project — not a commercial product with a support team. We do our best to keep it running, but we can't guarantee uptime or data preservation. Don't rely on it as your only record of anything important.
Don't use LM Tracker for anything illegal or harmful, don't try to access other people's data, and don't reverse-engineer it for commercial purposes. Use it as a workout tracker, be a good human, and we'll all get along fine.
LM Tracker is not a substitute for professional fitness advice. To the maximum extent permitted by law, our total liability to you is £0. It's free — we hope you love it, but use it at your own risk.
We may update the app, features, or these terms from time to time. We reserve the right to suspend accounts that abuse the service.
LM Tracker is not intended for anyone under 16. We don't knowingly collect data from children.
