# Algebra Step Solver: Privacy Policy
Effective 6 November 2026. Published at https://apps.digitalshijil.com/algebra-step-solver/privacy/
Algebra Step Solver ("the app") is published by DIGITAL SHIJIL LLC. Questions: contact@digitalshijil.com.
The short version
The equations you solve are stored on your phone only. The app has no account, no ads, no analytics, no backend and no network code of its own. The only data that leaves the device is the diagnostic logging that Google's Play Billing library sends to Google when the app talks to Google Play about the Pro purchase.
What the app stores on your phone
- History: each equation you solve, as you typed it, the kind of problem, a short form of the answer and the time.
- A few settings: the decimal mark and number of decimals, whether the reason for each step is shown, light or dark appearance, your practice score and chosen practice level, and when you last saved a copy.
This data lives in the app's private storage. The publisher never receives it and cannot see it. The steps themselves are worked out on the phone each time, by the app's own code.
Purchases and Google Play
Pro is sold by Google Play as a yearly subscription (with a free trial) or a one-time lifetime purchase. The app never sees your payment details. To check and restore the purchase, the app uses the Google Play Billing library, which exchanges purchase information with Google Play and sends Google diagnostic logs about the billing connection (Data safety: App info and performance > Diagnostics: collected, not shared, required). That logging is controlled by Google under the Google Privacy Policy: https://policies.google.com/privacy
Permissions
- The app asks for no permission of its own: no internet, notifications, camera, storage, media, contacts, location or microphone.
- The only permission in the release build is the Play Billing permission added by the billing library.
What the app does not do
- No account, sign-in or registration.
- No advertising, no advertising ID, no analytics and no crash-reporting SDK.
- No camera, no handwriting recognition and no artificial intelligence: the solutions are worked out by ordinary code on your phone.
- No upload of your equations or history, ever.
- No selling or sharing of your data with anyone.
Exports, backups and sharing
- Copied steps go to the clipboard. A solution shared as text or PDF, the history as CSV or PDF, and "Export all my data" (JSON) are created on the phone and shared only when you choose an app in Android's share sheet.
- A backup file (optionally protected with a password you choose) is written to a place you choose with the system file picker.
- If you use Android's own device backup, Android may include the app's data under your Google account's backup settings. The purchase cache is excluded from it.
Deleting your data
Settings > Delete all data erases the history and every setting on the device. "Clear the history" in the History tab removes just the saved solves. Uninstalling the app also removes everything it stored. A Pro purchase stays with your Google account and is restored by Google Play. If a subscription ends, nothing is deleted: your history stays on the phone, can be reopened and can be exported as JSON.
Results and schoolwork
The app does algebra on what you type, with exact fractions. It can make mistakes in how an input is read, and a teacher may ask for a different method. Check homework against your teacher's method.
Children
The app is not directed at children under 13 and is not designed for them.
Changes
If this policy changes, the new version is published at the address above with a new effective date before the change ships in the app.
