Your privacy,
in plain language.
Fizeke app privacy policy
Last updated: 16 October 2026
Fizeke is a fitness, food, exercise, weight and health tracking app. This policy covers both the Android app and the iOS app. The two are the same app and handle your information the same way; where a platform differs, it is marked Android or iPhone and iPad below. Fizeke is a one-time purchase, with no subscriptions, ads or personal data collection from the app.
The short version
Fizeke has no account system and no server. Your food diary, weight, body measurements, workouts, steps, health readings and settings are stored in a database on your own device. Fizeke does not upload these records to the developer or to a cloud server. You control any exports, and any access to your platform's health store, as described below.
The app’s optional online feature looks up unknown food barcodes through Open Food Facts. The lookup sends the barcode, not your diary or health records; the service also receives your IP address as part of the connection. You control whether lookups are allowed.
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 or tablet, 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, read from your platform's health store — or typed in by you
- 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
Records remain in the app until you delete them or clear its storage. Uninstalling removes Fizeke’s app-private data. You can export it yourself at any time from Profile → Your data, as either a database file or a folder of CSV files.
Health data from your other devices
iPhone and iPad. If you allow it, Fizeke reads from Apple Health what your watch, ring, scale, cuff or other health app has already recorded, and copies permitted readings into its own database on your device. Fizeke asks for read access only and never writes anything back to Apple Health. It does not pair with your watch or ring directly; those share their readings into Apple Health through their own apps first.
The readings Fizeke asks to read are: steps, body mass, body fat percentage, heart rate, resting heart rate, heart-rate variability, blood oxygen, respiratory rate, body temperature, blood glucose, blood pressure, VO₂ max and sleep analysis. Each is a separate grant you can allow or refuse on its own, and refusing one does not stop the others. Apple Health is an on-device store; reading from it involves no network. You can change or withdraw access at any time in the Health app, under Sharing. Withdrawing stops future reads; it does not erase readings already copied into Fizeke.
Android. If you turn on Health Connect, Fizeke reads what your watch, ring, scale or other health app has recorded and copies permitted readings into its own database on your phone. Rings and watches must share supported readings through their companion app into Android Health Connect first; Fizeke does not pair directly with them. Fizeke reads Health Connect data on your device, without uploading it.
Android. With your permission, Fizeke writes your weigh-ins to Health Connect, so other apps you authorize there can read them. Fizeke does not write your food diary or other records back. Health Connect grants are per measurement, and Fizeke treats them that way: you can allow steps and weight while refusing blood glucose. You can revoke access in Health Connect at any time. Revoking stops future reads; it does not erase readings already imported.
Android. Compatible Bluetooth chest straps and armbands connect directly using the standard Bluetooth heart-rate profile. Heart rate is read live during a session; workout heart-rate information is kept only when you save the workout. Bluetooth scanning is used to find a compatible monitor, not to determine your location. The iOS app has no Bluetooth feature and does not request Bluetooth access.
Vitals can also simply be typed in, on either platform. 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 device, and nowhere else.
Fizeke does not sign in to device manufacturers’ online services. Your ring, watch or other device’s companion app may have its own account, subscription, cloud-sync and privacy practices. Those are separate from Fizeke and depend on the device and app you choose.
The stress figure
Fizeke shows a stress indicator. It is not measured by anything and it is not sent anywhere: it is worked out on your device 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.
Fizeke is not a medical device and offers no medical advice.
Optional online barcode lookups
If you scan a barcode that is not in the app's built-in database, Fizeke 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. This disables Fizeke’s online barcode lookup. Built-in food search and everyday logging work offline.
Sharing a recipe, or an export
Fizeke can hand a recipe or a backup to your device's own share sheet, as a file. Nothing is uploaded by Fizeke when you do this: the file is written on your device and passed to whichever app you pick. Where it goes next, and that app's privacy practices, are your choice.
Permissions, and what each is for
| Permission | Platform | Why | Optional? |
|---|---|---|---|
| Camera | Both | 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. |
| Apple Health (read) | iPhone and iPad | Reading the steps, weight, body fat, heart rate, sleep, blood pressure, heart-rate variability, blood oxygen, breathing rate, body temperature, blood glucose and VO₂ max your devices have already recorded. Read-only: Fizeke never writes to Apple Health. Each reading is a separate grant. Apple Health 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 the Health app. |
| Health Connect | Android | The same readings as above, plus writing your 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. |
| Internet | Both | Only the barcode lookup described above. | Yes — set online lookup to Never. |
| Physical activity | Android | Reading the phone's built-in step counter, so daily steps appear in your diary. On iPhone and iPad, steps come from Apple Health instead, and Fizeke does not use the motion sensors directly. | Yes — without it, the phone’s built-in step counter is unavailable. Separately authorized Health Connect step data may still be available. |
| Notifications | Android | Showing only the reminders you switch on yourself (meals, weigh-in, workouts, step goal). The iOS app has no reminders and does not request notification access. | Yes — reminders are off by default. |
| Bluetooth (scan and connect) | Android | 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
Fizeke 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 the operating system's application sandbox — Android's on Android, iOS's file protection on iPhone and iPad — and by whatever screen lock and device encryption you have enabled. Exported backup and CSV files leave that protection. Store them securely and choose where you save or share them. If you place an export in cloud storage or send it to someone, that is your choice; the destination’s privacy practices apply. Fizeke does not maintain a developer-hosted backup.
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. The developer has no copy of your app records to retrieve or erase. Files you export, and records in Apple Health or Health Connect, are separate: manage or delete those in their respective locations. Back up records you want to keep before uninstalling or replacing your device.
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).
- Barcode decoding — runs entirely on your device, and no image or scan result is sent anywhere by Fizeke. On Android this uses Google ML Kit, with the model bundled inside the app. On iPhone and iPad it uses the barcode scanner built into iOS.
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.
