Battle Lifter privacy policy
Last updated: 20 October 2026. Battle Lifter is a gym tracker you can play against friends. It is made by James Taylor in Manchester, UK.
What the app collects
- Training data you enter: exercises, sets, weights, reps, how hard a set felt, sessions, your plan, body weight and measurements, and settings.
- Step counts: daily totals read from Android Health Connect, only if you allow it. They score your own walking target.
- Account details: if you create an account, your email address and the name you choose. Sign-in is handled by Clerk.
- Battle data: your Battle friends, challenges, battles, your share of your plan done, the city you pick for finding a fight, and the short cheers you send.
- Notification tokens: if you turn notifications on, a device token so we can tell you when a mate challenges you or a battle ends.
- Approximate location, once: only if you allow it during map setup, to find towns near you. It is not stored as a history and not tracked.
During the beta, the app records which screens you open, which buttons you tap, and app errors, linked to your account. It is used only to fix and improve the app, kept for 90 days, and never sold or shared. It does not include your workout numbers or notes.
Where it goes
- Everything is stored on your phone first. If you sign in, it is backed up to our database (Convex) so you can restore it and battle friends.
- What your friends see: your name, your share of your plan done in a battle, whether you are training, and cheers. They never see your weights, sets or body data.
- Google Gemini: if you upload your own plan as a PDF, the PDF is sent to Google's Gemini model to read it into a plan you then check. If you use the weekly review, a summary of that week's training (no name or email) is sent to Gemini to write it.
- Notifications: pushes go through Expo, Google (Android) or Apple (iPhone) push services. They see the message text, not your training history.
- We do not sell your data, show ads, or share it for advertising.
Health Connect
Battle Lifter reads step counts from Health Connect with your permission. They are used only to show your daily walking progress inside the app. They are stored with your backup if you have an account, and are never used for advertising or shared with a third party. You can revoke access at any time in Health Connect settings.
This website
When you tap Join the testers group or Open Battle Lifter on battlelifter.com, we record which link brought you here (for example a Reddit post), which button you tapped, and a random id saved in your browser so a second tap is not counted twice. No name, email or cookie is used. It only tells us which posts bring testers.
Deleting your account and data
Uninstalling the app removes everything on your phone. To delete your Battle Lifter account and everything in it (training backup, friends, battles, challenges, notification tokens), email james@powleads.com from the address you signed up with. Everything is deleted within 30 days; nothing is kept after that.
Children
Battle Lifter is not meant for children under 16.
