// SpoolForgeBench is an offline filament shelf and print log that weighs what is left on a spool, tracks moisture pickup, and turns a failed print into one setting to change.
[01] Information collected // inputs
None. SpoolForgeBench has no account system, no sign-in and no server. Nothing you type into the app is transmitted anywhere — everything you enter stays in the app's private storage on your device.
[02] Local storage // on-device
Kept in OS-level local storage on your device, never uploaded:
- The spools you track — material, brand, colour, spool and remaining weight, and when you opened them.
- The prints you log — the profile used, duration, outcome, failure notes and the settings you changed.
- Badges the app derives from your own print history.
- Your app settings — units, printer and profile defaults, and the screen-awake option.
Uninstalling the app deletes every byte.
[03] Permissions // runtime
SpoolForgeBench requests no runtime permissions. Its Android manifest declares none, and the iOS build asks for no camera, location, microphone, contacts or photo access. There is nothing to grant and nothing to revoke. The app can keep the screen from sleeping while you work at the printer, but that is a display setting rather than a permission, and it reads no data.
[04] Network // egress
SpoolForgeBench makes no network requests. It has no server, no API and no bundled endpoint — the app behaves identically with the device in airplane mode. The one time data leaves the app is when you tap a share action: that hands the text you chose to your operating system's share sheet, and you pick where it goes. Nothing is sent without that tap.
[05] Third parties // vendors
None. There is no analytics SDK, no advertising SDK, no crash reporter and no attribution or A/B-testing library in SpoolForgeBench. Its dependencies are user-interface and local-storage packages only, and none of them phone home.
[06] Children // coppa/gdpr-k
SpoolForgeBench is not directed at children and contains no ads, no in-app purchases and no social features. Because the app collects no personal information from anyone, it collects none from children either — there is nothing that could be knowingly gathered from a user under 13, or under 16 in the EEA and UK.
[07] Your rights // you
Because your data never leaves your device, you hold it directly — there is no copy on our side to request, export or erase. You can edit or delete any individual record from within SpoolForgeBench at any time. To remove everything at once, uninstall the app: that deletes its private storage, including every spool, print record and setting. There is no backup on our servers, so an uninstall is final.
[08] Changes // changelog
If this policy changes, the updated field at the top of this page will be revised. Material changes are also noted in the app's release notes.
