Summary
Tuck is designed so your data stays on your device. The app has no server; the developer cannot see your workouts or your videos.
The app
Your workout data — exercises, sets, skills, notes — is stored locally on your phone. It is not uploaded anywhere by the app.
Form-check videos are recorded only when you choose to record them. They are analysed on your device and stored on your phone. Nothing about a video leaves your phone unless you turn on the Google Drive archive.
The optional Google Drive archive uploads your clips and backups to a
folder in your own Google Drive, using Google sign-in with the
drive.file scope — Tuck can only see files it created, nothing
else in your Drive. You can disconnect it at any time in the app or from
your Google account settings.
Tuck contains no analytics SDKs, no advertising, and performs no server-side collection of any kind.
This website
The only information this site collects is the email address you submit to the early-access list. It is stored in our Cloudflare account and used solely to email you about Tuck's availability. Ask hello@tuck.fitness to be removed at any time. The site uses Cloudflare Web Analytics — cookieless, aggregate page counts with no personal identifiers — and is served by Cloudflare as a content delivery network.
Data deletion
Uninstalling the app removes all on-device data. Files in your Google Drive are yours — delete them whenever you like. Every email we send has an unsubscribe link; unsubscribing removes your address from the list.
