None. KitchenMetrics does not collect personal or sensitive user data. It does not ask for your name, email, phone number, location, contacts, photos, or any device identifier. There is no sign-in.
So you can resume work after closing the app, KitchenMetrics saves the values you type into its calculators — ingredient prices, yields, portion weights, equipment settings, cost parameters — on the device itself. Where it is kept, and what your operating system may then do with it, differs between Android and iOS, so the two are described separately below.
Data is stored in the app's private storage (SharedPreferences).
INTERNET permission still cannot send data itself, but the operating system can do it
on the app's behalf — Auto Backup copies app data to your Google Drive, and device-to-device
transfer copies it to a new phone during setup. Neither requires a permission from us. Both are
disabled explicitly in this build (android:allowBackup="false" plus a
dataExtractionRules file that excludes cloud backup and device transfer,
because on Android 12 and later the first setting alone does not stop the second).Data is stored inside the app's own sandbox, in two places that hold the same information: the web view's
local storage, and the system preferences store (UserDefaults). The second exists because iOS
treats web-view local storage as expendable and may clear it when the device runs short of space; the copy is
what stops a full working set of recipes from disappearing for that reason. Both locations are private to
KitchenMetrics and are not readable by other apps.
Apple backs up an app's sandbox as part of the device backup. If iCloud Backup is switched on in your iOS settings — it is on by default for many devices — then the data KitchenMetrics has saved is included in that backup and is copied to Apple's servers, along with the rest of your device. The same applies to an encrypted backup made to a computer.
We want to be exact about what this does and does not mean. We still receive nothing: the app sends nothing anywhere, and we operate no server and hold no copy of your data. The backup is made by your device, to your own Apple account, under your control and Apple's privacy terms — not to us and not to any third party we have chosen.
You can switch it off for this app in Settings → [your name] → iCloud → Manage Account Storage → Backups → [your device], where KitchenMetrics can be excluded individually.
The trade-off, stated plainly: leaving the backup on means your recipes survive a lost or replaced phone. Switching it off means they do not, exactly as on Android. Neither choice sends anything to us. We have deliberately not made this decision for you.
None. KitchenMetrics makes no network requests of any kind. It contacts no server, no analytics service and no third party. It works entirely offline, including in aeroplane mode.
On Android this is not only a policy — it is a property of the app itself. KitchenMetrics
does not hold the Android INTERNET permission, so the operating system will not permit it to send
anything anywhere, whatever its code might attempt.
On iOS we cannot make the same claim, and we would rather say so than repeat an Android sentence that does not apply. iOS has no equivalent permission to withhold: network access is not something an app must ask for, so there is no switch we can decline. What holds on iOS is that the app contains no networking code and no third-party SDK that could contain any. That is a weaker guarantee than Android's — it rests on the app being what we say it is, rather than on the operating system refusing — and calling it anything stronger would be untrue.
Earlier versions optionally queried USDA FoodData Central for public nutritional data. That lookup was removed on 13 July 2026. The scientific food data it provided is now embedded in the app itself.
None. We do not sell, rent or share data with anyone — we do not collect any.
KitchenMetrics contains no analytics SDK, no advertising SDK and no crash-reporting SDK. It does not track you across apps or websites, and builds no profile of you. It requests no tracking permission on iOS, because it has nothing to track you with.
KitchenMetrics requests no permission that grants access to your device or your data on either platform. It has no access to your location, camera, microphone, contacts, files or storage.
Android: in particular it does not hold the INTERNET
permission, so it cannot send anything anywhere. For completeness, the build contains one internal,
signature-level permission (DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION) that the Android support
libraries add automatically. It is scoped to this app, is used only so the app's own components can talk to
each other, and grants no access to anything on your phone. We mention it because it appears in the
manifest and we would rather list it than have you find it.
iOS: the app declares no usage descriptions, which is the mechanism by which an iOS app asks for the camera, the microphone, the photo library, location or contacts. An app that declares none cannot request them, and iOS will not present you with a prompt from KitchenMetrics for any of them.
KitchenMetrics is a professional tool for kitchen and hospitality work. It is not directed at children and does not knowingly collect data from anyone, including children.
Because we hold no personal data about you on any server, there is nothing for us to export, correct or delete. The data on your device is entirely under your control. On iOS, any copy held in an iCloud backup is likewise under your control, through your Apple account settings.
