What you should know before using NextBody
NextBody handles sensitive data (health, body photos, GPS, payments). Here is the full picture, spelled out.
Privacy policy (last updated: 7 February 2026)
NextBody™ places particular importance on protecting its users' privacy. DATA COLLECTED — Profile information provided by the user (age, weight, height, goals) · Data related to the use of the application · Photos voluntarily sent by the user (AI Photo feature) · Anonymous technical data (crash, performance, diagnostics). USE — Data is used only to: provide personalised sport and nutrition programmes, improve the user experience, generate analyses via artificial intelligence systems, ensure customer support. SHARING — NextBody™ does not sell any personal data. Some data may be processed by third-party services strictly necessary for the application to operate (AI services, Firebase hosting, Apple/Google payment). SECURITY — Technical and organisational measures are in place to protect data against any unauthorised access. YOUR RIGHTS — In accordance with applicable regulations, you can request access, rectification or deletion of your data by writing to support@omnixapps.com.
Health data (Apple Health / Health Connect)
If you turn on health integration, NextBody only READS: your weight, step count, sleep, heart rate and active calories. NextBody never writes to Apple Health or Health Connect. The data stays on your device — only aggregated values (today's weight, today's steps) are synced to Firestore to feed your tracking. You can revoke access anytime from iOS Settings > Health or Android Settings > Health Connect.
GPS location & runs
During a run, NextBody collects your GPS position continuously (including in the background with the screen locked) to record the track, distance, pace and calories. Tracks are stored in your Firestore space `runs/{runId}` and are never public by default. You can stop tracking anytime via the Stop button — collection stops immediately.
Data sent to our AI (coach + AI Photo)
Two distinct flows use our AI server (`nextbody-server.onrender.com`): CONVERSATIONAL COACH + PROACTIVE NOTIFICATIONS — send your Firebase user ID, language, text message and a JSON snapshot of your recent activity (number of sessions, streak, recent weight, runs, average RPE). No photo is sent in this flow. AI PHOTO FEATURE — when you voluntarily scan a meal or analyse a progress photo, the image is sent to our AI server for processing (dish recognition + macro estimate, or progress comparison). The image is not retained after processing and is never used to train a model. If you disable all notifications, never use the coach and never trigger an AI Photo scan, nothing is sent to that server.
Photos (camera, gallery, body photos)
NextBody uses your camera to: scan food product barcodes (OpenFoodFacts), photograph your meals (local macro analysis) and capture your progress photos. Progress photos are encrypted and stored in Firebase Storage under `users/{your-uid}/body_photos/`. They are only visible to you, unless you explicitly share a session on the social feed. Permanent deletion is available from the app.
Authentication & account deletion
You can sign in with email + password, with an email OTP code (via Brevo), with Google Sign-In or with Sign in with Apple. Account deletion is instant from Account > Delete account: we delete your Firebase Auth account, all your Firestore data (profile, workouts, runs, photos, measurements, nutrition, transactions), your Storage files and your local preferences. No residual backup.
Premium subscriptions & renewal
NextBody offers a Premium monthly (`premium_monthly`) and yearly subscription (`premium_yearly` on iOS / base plans `elite-monthly` and `elite-yearly` on Android). The subscription auto-renews unless cancelled at least 24h before the current period ends, from your Apple ID or Google Play settings. Payment is billed to your Apple/Google account. No direct refunds from OmniX AI — requests go through Apple (reportproblem.apple.com) or Google (play.google.com/store/account/subscriptions). Once cancelled, Premium access remains active until the end of the paid period.
Push notifications
NextBody uses Firebase Cloud Messaging to send: (1) daily reminder of tomorrow's scheduled training (8 pm Europe/Paris), (2) weekly summary on Sunday evening (8 pm), (3) proactive AI coach message if you haven't opened the app for 24h (6 pm). Categories: training, nutrition, water, tracking, vision, coach. Each category can be disabled individually from Settings > Notifications. You can also turn everything off with a single switch.
