Dilution Calculator — Privacy Policy
Last updated: 2026-09-12
OVERVIEW
Dilution Calculator does not require an account, and we do not sell personal information. The app stores its main feature data locally on your device. It also uses Google services for analytics, crash reporting, remote configuration, and advertising.
INFORMATION STORED ON YOUR DEVICE
The app stores the last calculation and saved product or mixture presets, including names, ratios, units, and update times. This data is used to restore calculations and saved mixtures.
The app may also store basic operating information such as app-use count, review-prompt state, temporary feature-unlock state, and cached advertising or More Apps configuration.
The developer does not run a server that receives your feature records. The app reads developer-controlled advertising settings and a More Apps list from Google Cloud Firestore, but its Firestore code does not upload your feature records.
ANALYTICS, CRASH REPORTING, AND ADS
Google Firebase Analytics may process limited app-usage and technical information, such as app launches, sessions, menu interactions, app version, device type, app-instance identifiers, and ad-performance events. The app does not intentionally include the feature records described above in its analytics events.
Google Firebase Crashlytics may process crash reports and related technical information needed to diagnose app problems.
The app uses Google AdMob. Google may process advertising identifiers and device, app, consent, network, and ad-performance information to provide and measure ads. Google advertising services may collect an IP address and use it to estimate an approximate location even when the app has no location permission.
PERMISSIONS AND ADVERTISING CHOICES
The app does not request access to your precise location, camera, microphone, contacts, photos, Bluetooth, health records, or notifications for its main features.
Where required, Google UMP may show an advertising-consent message. The app treats personalized advertising as disabled unless the consent result allows it. On iOS, the app considers the App Tracking Transparency prompt only after the UMP process and only when personalized advertising is allowed. The core app remains usable if tracking is not allowed.
You can manage iOS tracking permission in Settings. Where Google requires privacy options to remain available, open the app menu and tap “Privacy Choices” to review or change your Google advertising-consent selection. Google may not require this item in every region or consent state. Changing advertising consent does not delete the feature data stored locally on your device. To remove local app data, use an available in-app delete control, clear app data on Android, or delete the app on iOS. A device backup may preserve an older copy.
STORAGE AND YOUR CONTROL
Local data remains on your device until you delete it using an available app control, clear the app’s data, overwrite it through continued use, or uninstall the app. When a numeric limit is stated above, the oldest records are removed after the limit is reached.
Local data may be included in an Apple, Google, or device backup depending on your backup settings. Uninstalling the app normally removes the active local copy but may not remove an older backup.
Google retains data processed by Firebase and AdMob according to the applicable service, configuration, and Google policies. You can learn more here:

This app is a calculation aid, not safety advice. Always follow the product label and manufacturer instructions.
CHILDREN
The app is not directed to children under 13, and we do not knowingly collect personal information from children through an account or content-upload service.
CHANGES
We may update this policy if the app or its services change. The date above shows the latest revision.
