Summary
ProBuilder Calc is designed to keep your data on your device. We do not run our own servers for this app and do not sell personal data. Third-party SDKs (ads, analytics, crash reporting — only those listed below) have their own policies linked at the bottom.
Data we collect
- No account is required and we do not collect personal information on our own servers.
- Calculations, saved projects, and settings stay on your device.
- Third-party advertising (Google AdMob) may process device and usage data such as advertising identifiers, IP address, and app interaction data to serve and measure ads. In the EEA/UK ads are served only after your choice in Google's consent dialog; on iOS you can allow or deny tracking in the App Tracking Transparency prompt.
- Purchases are processed by Apple or Google; we receive only confirmation that a purchase occurred, not your payment details.
On-device data
Calculations, settings, and history you create stay on your device unless you explicitly export or share them (PDF/CSV/share sheet).
Permissions (optional, user-granted)
- Internet access — loading ads and processing in-app purchases.
- App Tracking Transparency (iOS, optional) — if you allow it, ads can be personalized; denying keeps ads non-personalized.
Advertising
This app is free and supported by ads served through Google AdMob. Personalized ads require your consent in the EEA/UK and tracking permission on iOS; otherwise non-personalized ads may be shown. Buying the ad-removal in-app purchase stops all ad requests.
In-app purchases
Free with ads. A one-time in-app purchase ($9.99; price varies by region) permanently removes ads. Payments are processed by Apple or Google; refunds follow store policy.
Children
This app is not directed at children under 13, and we do not knowingly collect their data.
Your rights and choices
- Revoke any permission anytime in system Settings.
- Delete on-device data by clearing app data or uninstalling.
- Contact us at support@chronos-labs.tech for questions or deletion requests.
Data retention & security
We retain nothing server-side for this app. On-device data persists until you delete it. No method of storage is 100% secure.
