NexCalc Privacy Policy
NexCalc is a local-first app. Your calculation history stay on your device, and NextEra.One does not collect them on a server.
Your calculation history and settings stay on your device.
NexCalc ships no advertising or analytics SDKs and sells no data.
NexCalc needs no network to do its job.
1. Scope
This Privacy Policy applies to the NexCalc Android app and the public NexCalc product pages operated by NextEra.One. It is written to explain how the app accesses, uses, stores and shares user data for Google Play review and for people using the app.
NexCalc does not require a NextEra.One account. If that changes, this policy will be updated before account features are released.
2. Data NexCalc accesses or stores on your device
NexCalc accesses data only for the features users would expect from this app.
| Data type | Purpose | Where it is stored |
|---|---|---|
| Calculation history (tape) | Show and reuse past results. | Local app storage on your device. |
| App settings | Remember angle mode, language and theme. | Local app storage on your device. |
3. Data collected by NextEra.One
NextEra.One does not operate an account service, analytics backend, advertising backend or sync backend for NexCalc. NexCalc does not upload your calculation history to NextEra.One.
The public website may receive ordinary web server request information from visitors, such as IP address, browser type and requested page, through the hosting provider used to publish these static pages. The app itself does not send your data to that website.
4. Data sharing and user-initiated transfers
NexCalc does not sell personal and sensitive user data. Data can leave your device in these user-initiated cases:
- NexCalc works entirely offline; nothing is sent anywhere.
- If you install or open the app through Google Play, Google processes Play Store data under Google's policies.
5. Permissions
NexCalc asks for Android permissions only when needed for its features.
- Notifications: show alerts you choose to receive
- Storage: keep your data in the app's own local store
6. Retention and deletion
- Your calculation history remain in NexCalc's local store until you delete them or clear everything.
- Local settings remain on device until you change them or uninstall the app.
- NextEra.One cannot recover deleted local data because it is not synced to a NextEra.One server.
- You can also use Android Settings > Apps > NexCalc > Storage > Clear storage to remove local app data.
7. Security
NexCalc relies on Android runtime permissions, Android app sandboxing and local device storage. Because NexCalc does not run a cloud sync service, there is no NextEra.One server copy of your calculation history. Anything you choose to share into other apps is governed by those providers' practices.
8. Children
NexCalc is not directed to children. It is a general-purpose tool intended for users who are allowed to manage their own content on their Android device.
9. Changes and contact
NextEra.One may update this policy when NexCalc changes how it handles data. Material changes will be reflected on this page with a new effective date.
