1Delete your in-app data (history, saved, favorites, settings)
This data is stored only on your device. To delete it in VectraCalc — All-in-One Calculator:
- Open the app and go to Settings (bottom navigation).
- Scroll to the Data section.
- Tap Clear history, Clear saved calculations, and/or Clear favorites. Each asks you to confirm.
- To restore all preferences to defaults, tap Reset settings.
Or delete everything at once by uninstalling the app — this removes all VectraCalc data from your device immediately.
2Delete advertising data collected by Google
To keep the app free, VectraCalc shows ads via Google AdMob, which collects your device's advertising ID and an approximate (IP-based) location. This data is held by Google, not by us. You can control and delete it:
- Reset or delete your advertising ID: on your device, open Settings → Google → Ads, then choose Delete advertising ID or Reset advertising ID.
- Remove ads entirely: upgrade to VectraCalc Pro in the app — Pro users are shown no ads.
- Manage data held by Google: use Google's account privacy tools at myactivity.google.com and see the Google Privacy Policy.

| Advertising ID & ad data | Google (AdMob) | Deleted / reset via device Google settings |

Your Pro purchase records are kept by Google Play, not by us. They are what let your Pro plan restore after reinstalling or on another device. To manage them, use Google Play → Payments & subscriptions. We do not store or control this data. There is no additional retention period for any data on our side, because we operate no servers and store nothing off your device.
