KaKontrata: Estimator PH ("the app") is published by MAK-CT Construction OPC ("we").
The short version: the app works entirely on your device. We do not collect, store, transmit, sell, or share any personal data.
Details
No accounts. The app has no login or registration.
No data collection. We do not collect names, contact details, location, device identifiers, usage analytics, or any other personal information.
On-device storage only. Material prices you edit and quotes you build are saved in your device's local app storage so they're there the next time you open the app. This data never leaves your device. Uninstalling the app deletes it.
No internet required. The app functions fully offline and makes no network requests.
Sharing is user-initiated. When you tap "I-share ang Quote," your device's own share sheet sends the quote text to the app you choose (for example, Messenger). We are not part of that transmission and never see its contents.
Children
The app is a general-audience utility tool and is not directed at children. It collects no data from anyone, including children.
Future versions
If a future update adds features that change any of the above (for example, optional ads), we will update this policy and the Google Play Data safety section before that version is released.
Disclaimer on estimates
Outputs are material quantity estimates only, based on standard Philippine estimating references. They are not structural designs or engineering advice. Consult a licensed civil engineer for design, and a local supplier for current prices.
