Privacy Policy

1. Your calculations stay on your device

Saved calculations, stock names, and your theme and language settings are stored only on your device. They are never sent to the Operator's servers, and the Operator cannot see them. Deleting the app deletes them — there is no separate backup.

2. What is collected for ads

This app shows Google AdMob ads so it can stay free. To serve ads and prevent click fraud, Google may collect:

• Advertising ID (a resettable identifier assigned to your device)
• IP address and approximate region
• Device model and operating system version
• Records of ads viewed or tapped

Collection and use follow the Google Privacy Policy. The numbers you enter and the records you save are never sent with ads.

3. You can turn it off

You can reset or delete your advertising ID under your device's Settings › Privacy › Ads. After deletion, personalised ads stop and unrelated ads are shown instead.

4. Not directed at children

This app is not designed for children under 16, and it does not knowingly collect children's personal information.
