GainBite privacy

GainBite is a private app for a small invited group. This page explains what it stores and why.

What GainBite stores

• Your account: name, email and a scrambled (hashed) password.
• What you log: workouts, meals, weigh-ins and your profile (age, height, sex, goal), so they are backed up and reach your other devices.
• Progress photos: encrypted on your phone with a key made from your password before they are uploaded. The server only holds the encrypted copy and cannot see them.
• Health numbers: each day's steps, active calories and weight, read from Health Connect (Android) or sent by your Apple Shortcut (iPhone). They are used only to work out your daily calorie burn.
• Meal photos for the AI scan: sent once to the AI service to estimate calories, and not kept afterwards.

Health Connect

On Android, GainBite asks to read steps, active calories burned and weight. It never writes to Health Connect, never reads anything else, and you can remove access at any time in Health Connect's settings.
