Privacy Policy
Bitwright — engineering calculator by Mintwright. Last updated October 1, 2026.
Summary
Bitwright collects no data. It has no user accounts, no analytics, no advertising, and no crash reporting. The Android app requests no permissions of any kind, including network access.
What is collected
Nothing, with one exception in the web edition: its license key is sent to be confirmed, as Network access describes. The categories below are listed so the answer is unambiguous.
| Category | Collected | Shared |
|---|---|---|
| Personal identifiers (name, email, address) | No | No |
| Location | No | No |
| Contacts, photos, files, calendar | No | No |
| Device or advertising identifiers | No | No |
| Usage or diagnostic data | No | No |
| Calculations, expressions, and history | No | No |
| License key (web edition only) | Sent to confirm it; not kept by Mintwright | The storefront that issued it |
Where your calculations go
Nowhere. Expressions, history, variables, and settings are held on your own device — in the app's local storage in the browser build, and in the app's private storage on Android. They are never transmitted. Clearing the app's history, or uninstalling it, removes them.
Network access
-
Android app: the app declares no permissions at all,
not even
INTERNET. Every file it loads is served from inside the installed package. It works with the radio off. - Web app: your browser downloads the app's files from the host that serves this page, which — like every web server — sees the request. After the first visit the app is cached and runs offline. The web edition makes one other kind of request. When a license key is entered, and at most once a week afterwards, it sends the key to Mintwright's activation service, which confirms the key with the storefront that issued it (Payhip) and counts the device. The request carries the key and nothing else from the app: no calculation and no history. The activation service keeps no record of it; the storefront keeps the count. Bitwright contacts no other service.
Cookies and tracking
Bitwright sets no cookies and uses no tracking technology of any kind.
This website, mintwright.app, counts its page views with Cloudflare Web Analytics, which sets no cookies and does not identify visitors. The app is not counted.
Third parties
Bitwright contains no third-party libraries, SDKs, analytics, or advertising code. If you obtained the app from Google Play, Google's own privacy policy governs the store transaction and the purchase record; that is between you and Google, and Bitwright receives none of it.
Children
Bitwright is a technical tool with no social features, no user-generated content, and no collection of personal information. It is safe for any age, and it collects no personal information from anyone, children included.
Changes
If this policy ever changes, the revised version will be posted here with a new date. Because the app collects nothing, no change could apply retroactively to data — there is none to apply it to.
