Privacy policy
Modus – Body & Mind (Android, Wear OS and iPhone)
Last updated: 2026-11-11
In short
- Modus has no accounts. You do not sign up, and Modus never asks for your name or email.
- Everything you enter or the app reads (workouts, meals, photos, water, weight, sleep, heart rate, supplements and so on) is stored on your phone.
- Data leaves your phone only when you use a feature that needs it: AI analysis, product lookup or sharing a product, your own backup, sharing with a coach you invite, or a purchase.
- Modus does not sell data, does not show ads and does not use advertising or analytics trackers.
Data stored on your phone
Your profile (age, sex, height, goals), workouts and exercises, meals and meal photos, water, weight and body fat, sleep, stress, heart-rate and ECG readings from your watch, supplements and medicines with their reminders, and your settings. This data stays on your device. It is deleted when you delete it in the app or uninstall Modus.
Health Connect, Apple Health and your watch
With your permission Modus reads activity, exercise, heart rate, heart-rate variability, sleep, weight, body fat, VO₂max, blood oxygen, breathing rate and skin temperature. The Modus watch app sends its measurements to the phone over a direct connection. This data is used only to show your statistics and estimates in the app. It is not sold, not used for advertising and not shared with anyone, except that the calories and workouts of a day can be part of an AI request that you start yourself (see below). Modus’s use of information received from Health Connect adheres to the Health Connect Permissions policy, including the Limited Use requirements. You can withdraw these permissions at any time in Health Connect or in the iPhone Health app.
AI features
When you start an AI feature – analysing a meal photo or a package label, the daily healthy eating check, checking a supplement, or translating your past results – the app sends what is needed for it to the Modus server: the photo or text, plus your age, sex, height, weight, daily goals and that day’s food, drinks, workouts and calories burned. The Modus server forwards the request to an AI processing provider and returns the answer to your phone. Modus does not store the photos or texts. The provider processes them only to produce the answer, does not use them to train its models, and may keep request data for up to 30 days for abuse monitoring before deleting it.
Product database
When you scan a barcode, only the barcode number is sent to look the product up in public food databases. If you choose to add a missing product or a product name, the product name, nutrition values and the label photo are published in that public database under Modus’s own contributor account, without any information about you. Products you add from a package label or by typing in their values (name, nutrition values, portion size and barcode, if there is one) are also added to a shared Modus product list, so other Modus users can find them by barcode or by name; nothing about you is stored with them. Sharing can be turned off with the switch shown when you add a product.
Sharing with a companion (for example a coach)
If you choose to share with a coach, you enter the coach’s invitation code and pick categories (training, food, water, sleep, recovery, body). For each day, a summary of only those categories is encrypted on your phone with the coach’s key and stored on the Modus server for up to 90 days. The server cannot read these summaries; only the coach’s phone can. The server keeps only which anonymous athlete is linked to which coach, the chosen categories and when data was last updated and viewed. You can change the categories or stop sharing at any time in Settings → Companion; stopping (or the coach removing you) deletes everything that was shared. A reminder asks every 30 days whether you still want to share. Coaches must use the data only to coach you.
Your WHOOP account
If you connect your WHOOP account in Settings → Connections, you sign in on WHOOP’s own page and allow Modus to read your recovery, sleep, workouts, day strain and body measurements (not your profile). The Modus server keeps only the access key WHOOP gives for this, encrypted, so it can fetch your data when the app asks; the data itself is passed straight to your phone and is not stored on the server. You can disconnect at any time in the app – the key is then deleted and WHOOP is told to remove Modus’s access. Deleting your data on the server does the same.
Bluetooth heart rate sensor
If you connect a Bluetooth heart rate sensor (a chest strap, or a band such as WHOOP that broadcasts heart rate), Modus reads only the heart rate it sends, directly on your phone. It is shown live and saved with your workout on your phone; it is not sent to the Modus server. Bluetooth is used only to find and connect to the sensor you choose; on Android 11 and older the system calls this a location permission, but Modus does not read your location.
What the Modus server keeps
Only technical records, linked to an anonymous identifier (not your name, email or phone number): your subscription or tester-access status, how much of your monthly AI allowance you have used, and the app and watch app version you last used. The server does not keep your health data, meals, photos or location. A short log of server errors, with no personal data, is kept for up to 14 days.
Purchases
Subscriptions are handled by Google Play or the App Store. Modus receives only the purchase status needed to unlock features; it never sees your payment details.
Backups
If you turn on backup, your data is saved to your own Google Drive (Modus can only see the files it created there) or to a file you choose. Modus has no access to these backups on its server.
Who receives data
Only the service providers needed to run the features above: the cloud hosting provider of the Modus server, the AI processing provider, the public open food database (barcodes and products you choose to share), and Google Play or the App Store for purchases. Data is sent over encrypted connections (HTTPS). Nothing is sold or shared for advertising.
Keeping and deleting data
Data on your phone stays until you delete it or uninstall the app. The server records can be deleted at any time in the app (Settings → AI settings → Delete my data on the server) or as described on the data deletion page.
Your rights
You can see, change, export and delete your data in the app at any time. Under the GDPR and similar laws you may also ask for access to or deletion of the server records and complain to your data protection authority. Because Modus has no accounts, the server cannot link records to your name.
Children
Modus is not directed at children under 16 and does not knowingly collect their data.
Changes
If this policy changes, the new version is published on this page with a new date.
