BuildCalc ("the app") is developed by Akbar Uktamaliev ("we", "the developer"). This policy explains what data the app handles and why.
WHAT THE APP COLLECTS ITSELF
Nothing. BuildCalc has no accounts, no registration and no server of its own. All calculations run entirely on your device. The numbers you enter are never transmitted anywhere and are not stored after you close the screen.
The app stores two small settings on your device only: your chosen interface language and whether you have purchased the ad-free version. This data never leaves your phone.
DATA COLLECTED BY THIRD PARTIES
The app shows advertising through Google AdMob. To serve and measure ads, Google collects advertising identifiers and other device identifiers, information about how you interact with ads, and general diagnostic and performance information about the app.
This data is collected and used by Google, not by us. We never receive your personal data, and we cannot identify individual users. Google's handling of this data is described in the Google Privacy Policy at https://policies.google.com/privacy
If you buy the ad-free version, the purchase is processed by Google Play Billing. We receive only the fact that the purchase exists, never your payment details.
PERMISSIONS
The app requests no sensitive permissions. It has no access to your storage, location, contacts, camera or microphone. Internet access is used only to load advertising.
YOUR CHOICES
You can reset or delete your advertising identifier at any time in Settings, Google, Ads on your Android device. Buying the ad-free version stops all advertising and the related data collection.
CHILDREN
BuildCalc is a professional tool for construction and repair work. It is not directed at children and we do not knowingly collect data from children.
CHANGES
If this policy changes, the updated version will be published at this address with a new date at the top.
