Privacy Policy - All-in-Math

Effective date: November 2026

All-in-Math ("All-in-one: The Ultimate Calculator") respects your privacy. The app works entirely offline, does not require an account, contains no advertising, and does not collect, transmit or share any personal information.

Operator: Rainy Day Logic.

INFORMATION WE COLLECT

We do not collect any personal data. The app does not ask for your name, email address, location or any other personal information, and there is no sign-up or login.

DATA STORED ON YOUR DEVICE

The app stores two small files on your own computer so it can remember your preferences:

• layout.txt — the position of the divider between the calculator list and the work area.
• inputs.json — the last values you typed into each calculator, so you can pick up where you left off.

These files are stored locally in your Windows application-data folder (%LocalAppData%\All-in-Math). They never leave your device, are not encrypted or transmitted anywhere, and you can delete them at any time — deleting them simply resets the app to defaults. Uninstalling the app does not remove them automatically; you may delete the All-in-Math folder manually if you wish.

INTERNET ACCESS

The app makes no network connections. It does not use cookies, analytics, crash-reporting services or any third-party services.

CHILDREN'S PRIVACY

The app is suitable for all ages and collects no personal information from anyone, including children.

CHANGES TO THIS POLICY

If this policy changes, the updated version will be posted at this location with a new effective date.
