Convertora is a unit, ingredient and recipe converter made by CJ Designs. It is an offline calculator: everything it does happens on your own device, and it has no server, no account system, and nothing to sign in to.
Convertora collects nothing, sends nothing, and has no account. There is no analytics SDK, no advertising SDK, and no crash-reporting service in the app. On Android it is not even granted the INTERNET permission, so it cannot open a network connection at all. Your conversions, favourites, history and recipes stay on your phone.
Nothing. We do not collect, receive, store or process any personal data about you. There is no server to send it to. We cannot see what you convert, how often you open the app, or that you have installed it.
All of the following is written only to Convertora's own private storage area on your device, and is never transmitted anywhere:
Convertora does not request access to your location, contacts, camera, microphone, photos or files, and does not need any of them to work. This is not just a promise about intent — the app is built without them:
android.permission.INTERNET is absent, which is what makes network access impossible rather than merely unused.Info.plist contains no privacy usage descriptions of any kind, so iOS can never present you with a permission prompt for Convertora — an app cannot access a protected resource it has declared no purpose string for.Convertora contains no advertising SDK, no analytics SDK, no attribution SDK, and no third-party tracking of any kind. It does not use an advertising identifier, and there is no in-app purchase or subscription system, so there is no payment data either. This has been checked against the app's full dependency list, reproduced below.
| Component | What it does | Sends data off-device? |
|---|---|---|
| Flutter & Dart | The app framework itself | No |
| Riverpod | In-app state management | No |
| Hive | Local storage for favourites, history and recipes | No |
| SharedPreferences | Local storage for settings | No |
| share_plus | Hands text to your device's own share sheet, only when you tap Share | No — it passes the text to the OS, and you choose where it goes |
| rational | Exact arithmetic for digital-storage conversions | No |
| package_info_plus | Reads the app's own version number for the About screen | No |
| intl | Number and text formatting | No |
| flutter_native_splash | Holds the launch screen while the app starts | No |
Content only ever leaves the app when you explicitly tap a share action — for example, sharing a scaled recipe. Convertora hands that text to your device's native share sheet and stops there. Whatever happens next is between you and the app you chose to send it to, under that app's own privacy policy.
Convertora's ingredient figures ship inside the app as a bundled data file. Looking up an ingredient is a local lookup — nothing is requested from a server, and no record is made of which ingredients you look up beyond your own on-device history.
Convertora is suitable for general audiences and collects no personal information from anyone, including children.
Because nothing is stored off your device, there is no account to close and no deletion request to send us. You are in full control:
If this policy changes, the updated version will be posted at this address with a new effective date. The version of the app a policy applies to can always be checked in Settings → About Convertora.
