Who holds the data
Thành Luân, an individual in Vietnam, decides why the data is kept. The database, sign-in service and files are on Supabase in Singapore (ap-southeast-1).
Who can use the app
People aged 16 and over. Under 16 cannot create an account. From 16 until 18, Bell uses only the gentle voice and does not accept body measurements.
What the app stores
- Account: email, name, username, photo, year of birth.
- Workouts: exercises, sets, load, reps, time, notes, personal records.
- Weight, measurements and InBody sheets, if you enter them.
- Friends, invites, reactions and shared routines, if you use those parts.
- A link to a training partner, and only the parts you turn on for them.
Stays on the phone
- Sleep read from the phone’s health store. It is not uploaded, not sent to Bell, and not shown to friends or a training partner.
- Bell chat text on the device.
Three switches, off by default
- Friends can see workouts and achievements. Turn this on during setup or in the Me tab. Off means new workouts stay hidden.
- Send body measurements to Bell. The switch is on the Bell screen. Under 18 there is no switch.
- Weather on Today. On asks for an approximate location, rounded to about 1 km, sent through Supabase in Singapore to Apple WeatherKit. No location history is stored. The switch exists only in builds where WeatherKit is enabled.
Workout notes do not go to the feed or to Bell. Weight, measurements, photos, sleep and food have no switch that shows them to friends.
Bell
If you turn on “Let Bell AI use training numbers”, the app sends your goal, experience, schedule, equipment and summarized training numbers. It does not send your name, email, photos or notes. The request goes through Supabase in Singapore. It is not yet sent to a separate AI company. When that company is chosen, this page will name them before any data is sent.
If the switch is off, Bell speaks only with lines stored in the app.
Sign-in
If you sign in with email, Apple or Google, that service knows the address used to enter Banterbell. The app does not keep your password in a readable form.
How long
Until you delete the account. Deleting in the app removes your files on the server, then the account and the rows tied to it. A host backup may remain for a short time under Supabase’s backup practice. The app does not sell data and does not run ads that follow you into other apps.
What you can do
- View and edit your profile, workouts and measurements in the app.
- Export workouts to CSV from the Me tab.
- Turn each switch off. Off withdraws consent for that use.
- Delete the account in Me, or use Delete account if the app is already gone.
