The short version
- Our apps have no accounts and no sign-up. We do not run servers that receive your data.
- Your photos, game progress, settings and measurements stay on your phone.
- The apps are free and show ads from Google AdMob. AdMob collects some device data to serve and measure ads, as described below.
Data the apps handle on your device
| App | What it uses | Where it goes |
|---|---|---|
| Photo & Signature Resizer | Photos you choose or take, through the system photo picker or camera | Processed on your phone only. Never uploaded. Saved or shared only when you tap Save or Share. |
| Sudoku | Game progress, statistics, settings | Stored on your phone only. |
| Sensor Toolbox | Motion and magnetic sensors (accelerometer, magnetometer), screen density | Read live to show measurements; calibration values are stored on your phone only. |
| PDF Toolkit | PDFs and photos you choose (system file and photo pickers); document scans made with Google Play services' on-device document scanner | Processed on your phone only. Never uploaded. Output files are kept in the app's private storage until you save, share or delete them. |
| Minesweeper | Game progress, statistics, settings | Stored on your phone only. |
| 2 Player Games | Match scores, player names you type, settings | Stored on your phone only. |
Uninstalling an app deletes its data from your phone.
Advertising (Google AdMob)
The apps show ads provided by Google AdMob. To serve, personalize (where allowed) and measure ads and to prevent fraud, Google may collect:
- the device's advertising ID, IP address and approximate location derived from it;
- device and app information (model, OS version, language, app version);
- ad interactions (ads shown and tapped).
Google processes this data under its own policies: How Google uses information from sites or apps that use its services and the Google Privacy Policy.
Your choices. If you are in the European Economic Area, the UK or Switzerland, the app asks for your consent before personalized ads are shown, and you can change it at any time under Settings → Ad privacy choices. On any Android phone you can reset or delete your advertising ID in Settings → Privacy → Ads. Users in regions where personalized ads are not allowed receive non-personalized ads.
Children
Our apps are not directed at children under 13 and we do not knowingly collect personal data from children. Ads are limited to a family-friendly content rating.
Security and retention
We do not collect or store your personal data on our own servers, so we hold nothing to retain or delete. Data collected by Google AdMob is retained according to Google's policies.
Changes
If an app starts using a new service (for example crash reporting), we will update this page and the app's Data safety section on Google Play before releasing that version.
