PhysiqTrack — Privacy Policy
Last updated: 8 September 2026
PhysiqTrack is an offline food and training diary for Android, published by Jeremy Sayers. This policy explains what the app does with information. It is short because the app does very little with it.

The short version
PhysiqTrack has no account system and no server. Everything you record — your food diary, weight, body measurements, workouts, steps and settings — is stored in a database file on your own device and is never sent anywhere.
The app makes exactly one network request, and only when you ask it to: looking up a barcode you have scanned that is not in the built-in food database. That request contains the barcode and nothing else.
What we collect
We collect nothing. There is no analytics, no crash reporting, no advertising SDK, no tracking identifier, and no account. The developer has no ability to see, retrieve or delete anything you record, because none of it reaches us.
What the app stores on your device
All of the following stays on your phone, in the app's private storage:
- The food diary: what you logged, when, and its nutrition figures
- Foods you create yourself, and foods saved from a barcode lookup
- Recipes, saved meals and meal plans
- Workouts, sets, cardio sessions and personal records
- Weight, body-fat and body-measurement history
- Daily step counts and water intake
- Heart rate, sleep and the vitals below, when you connect a watch, ring, cuff or heart-rate strap — or when you type them in yourself
- Blood pressure, heart-rate variability, blood oxygen, breathing rate, body temperature, blood glucose and VO₂ max
- Your profile: sex, year of birth, height, weight, activity level, goals and targets
- App settings: language, units, colour scheme, reminders
This data is removed when you uninstall the app. You can export it yourself at any time from Profile → Export data, as either a database file or a folder of CSV files.
Connected devices
If you turn on Health Connect, PhysiqTrack reads what your watch, ring, scale or other health app has recorded and copies it into its own database on your phone. Health Connect is part of Android and holds that data on the device — reading from it involves no network request and no third party.
PhysiqTrack writes one thing back: your weigh-ins, so other health apps stay in step. Nothing else is written.
Health Connect grants are per measurement, and PhysiqTrack treats them that way: allow steps and weight but refuse blood glucose and it reads the first two and never asks again about the third. Nothing is read that you have not granted.
Vitals can also simply be typed in. A blood pressure cuff or a thermometer usually has no app at all, and a reading you enter by hand is stored exactly like one from a device — on your phone, and nowhere else.
A Bluetooth heart-rate strap is read live during a session. The reading is kept only if you save a workout with it.
Deliberately, PhysiqTrack does not connect to Fitbit, Oura, Whoop, Garmin or any other manufacturer's online service. Those need an account and send your identity to that company. Health Connect gets the same data without any of that.
The stress figure
PhysiqTrack shows a stress indicator. It is not measured by anything and it is not sent anywhere: it is worked out on your phone from your own heart-rate variability compared with your own fortnight baseline. It is an indicator, not a diagnosis, and the app says so where it is shown.
PhysiqTrack is not a medical device and offers no medical advice.
The one network request
If you scan a barcode that is not in the app's built-in database, PhysiqTrack can look it up in Open Food Facts (https://world.openfoodfacts.org), a public, open food database.
- This never happens automatically unless you choose it. By default the app asks you each time, and you can decline.
- The request contains the barcode only. No account, no device identifier, no location, and nothing from your diary.
- Open Food Facts will receive your device's IP address, as any website does when your device contacts it. Their privacy policy applies to that request: https://world.openfoodfacts.org/privacy
- The product information that comes back is saved into your own food list on your device, so the same product is recognised offline in future.
- You can turn this off completely in Profile → Look up unknown barcodes online → Never. With it set to Never, PhysiqTrack makes no network requests at all.
Permissions, and what each is for
| Permission | Why | Optional? |
|---|---|---|
| Camera | Reading a barcode from a package. Frames go straight to the on-device barcode decoder and are discarded. No photo is taken, saved or transmitted. | Yes — the app works fully without it; you just cannot scan. |
| Internet | Only the barcode lookup described above. | Yes — set online lookup to Never. |
| Physical activity | Reading the phone's built-in step counter, so daily steps appear in your diary. | Yes — decline it and the step tile stays at zero. |
| Notifications | Showing only the reminders you switch on yourself (meals, weigh-in, workouts, step goal). | Yes — reminders are off by default. |
| Health Connect | Reading steps, weight, body fat, heart rate, sleep, workouts, blood pressure, heart-rate variability, blood oxygen, breathing rate, body temperature, blood glucose and VO₂ max that your watch, ring, cuff or scale has already recorded, and writing weigh-ins back so other health apps stay in step. Each of these is a separate permission you can grant or refuse on its own. Health Connect is an on-device store; none of this involves a network. | Yes — off until you connect it, and you can withdraw access at any time in Health Connect. |
| Bluetooth (scan and connect) | Finding and reading a heart-rate strap over the standard Bluetooth heart-rate profile. Declared neverForLocation: the scan filters on the heart-rate service and no location is requested or derived. | Yes — only used when you tap to find a strap. |
Children
PhysiqTrack is not directed at children under 13 and we do not knowingly collect information from anyone. As the app collects no data at all, no information about a child is ever transmitted or stored by the developer.
Data sharing and selling
We do not share, sell, rent or transfer any personal information, because we do not receive any.
Security
Your data is held in your device's app-private storage, protected by Android's application sandbox and by whatever screen lock and device encryption you have enabled. Exported backup files leave that protection — treat an exported file the way you would any other personal document.
Your rights
Because your data never leaves your device, you exercise your rights directly: view it in the app, export it, edit it, or delete it by removing entries or uninstalling the app. There is no copy of it anywhere else for us to produce or erase.
Third-party data sources
- USDA FoodData Central — the built-in food database. Public domain. No request is made to USDA at runtime; the data ships inside the app.
- Open Food Facts — used only for the optional barcode lookup described above. Their data is provided under the Open Database License (ODbL).
- Google ML Kit (barcode scanning) — the barcode decoder runs entirely on your device. The model is bundled inside the app; no image or scan result is sent to Google by PhysiqTrack.
Changes to this policy
If this policy changes, the new version will be published at this URL and the date at the top updated. Material changes that affect what leaves your device will also be described in the app's release notes.
