AB Dev Lab ("we", "us") builds the mobile apps listed below. This policy explains what data those apps handle. None of our apps have an account or sign-in, and we do not collect, store, or share any personal information ourselves.
The section below applies to all of our apps; each app then has its own section describing exactly what it stores and which permissions it uses.
None of our apps require an account or sign-in. The content you create in an app is stored only on your device — we do not collect it or transmit it to our servers. Uninstalling an app removes its data. If your device has backup enabled, Android may include an app's data in your own personal Google Drive backup.
Our apps do not use your contacts, camera, microphone, precise location, or files.
Our apps show ads through Google AdMob. To serve and measure ads, Google and its partners may collect and process data such as your device's advertising ID, general (coarse) device and usage information, ad-interaction data, and approximate location derived from your IP address. This is done by Google, not by us. Google's handling of this data is described in Google's Privacy Policy and in How Google uses information from sites or apps that use our services.
Where required (e.g., EEA/UK), a consent prompt appears before personalised ads, and you can change or withdraw consent from that in-app prompt. You can also reset or delete your advertising ID and opt out of ad personalisation in your device settings (Settings → Google → Ads).
Our apps are not directed to children under 13, and we do not knowingly collect personal data from children. Ads are served in a non-personalised / age-appropriate manner where required.
Clear an app's storage or uninstall it to delete all of that app's locally stored data. For ad-related data, refer to Google's policies linked above.
We may update this policy from time to time, including when we add a new app. Material changes will be reflected by updating the "Last updated" date above.
