Mudly ("the app", "we", "us") is a concrete volume calculator operated by TON CO., LTD. This policy explains what information is involved when you use Mudly and the choices you have. We designed Mudly to keep your data on your device — we do not run servers, and we do not require an account.

The short version

• Your calculations stay on your device. Everything you type — dimensions, saved pours, project sections, settings — is stored locally on your phone and is never sent to us or to any server.
• We have no account and no server. You never sign up, and we never see your data.
• The app is free, supported by ads. Ads are provided by Google AdMob, which collects some device information to serve and measure ads. You control this through the consent choices described below.
• You can remove ads with a one-time purchase. Payment is handled entirely by the App Store or Google Play; we never see your payment details.

Information stored on your device

The following is created and kept only on your device and is not transmitted to us:

• App settings (unit system, default waste factor, default bag size).
• Your calculation history and saved project sections.

Uninstalling the app removes this data.

Information collected automatically for advertising

Mudly shows ads through Google AdMob. To serve, cap, and measure ads, Google and its advertising partners may collect and process:

• Device and app information (device model, operating system version, app version, language, coarse location inferred from IP address).
• Advertising and device identifiers. On iOS, the identifier for advertisers (IDFA) is only used if you allow tracking (see "Apple App Tracking Transparency" below); otherwise non-personalized signals are used.
• Ad-interaction data (which ads were shown, tapped, and general performance).
• Diagnostic and performance data used by the advertising SDK, such as non-user-related crash logs, app launch time, hang rate, and energy usage.

This processing is carried out by Google as an independent party under Google's Privacy Policy (https://policies.google.com/privacy) and Google's advertising terms. See "How Google uses information" at https://policies.google.com/technologies/partner-sites. The list of advertising partners is available in the consent form shown inside the app.

We do not ourselves collect analytics and we do not use any third-party analytics SDK.
