App identity.
This privacy policy applies to the Android app Spirit Level & Bubble Level (package name: com.play3rs.bubblelevel), published on Google Play under the developer name Play3rs. The developer and legal entity responsible for the app and for this policy (data controller) is Leroy Eric, sole trader trading as Play3rs, Le Floréal, 18 bis Rue Bricka, 06160 Antibes, France (contact: support@z-ax.com).
Bubble Level works without an account, and we do not ask for your name, email address, or precise location. Everything you create or record in the app is stored only on your device and is deleted when you uninstall the app.
Advertising (Google AdMob). Subject to consent, AdMob may process your advertising ID, device identifiers, app-usage/ad-interaction data, and coarse IP-based location to serve/measure ads. In the EEA/UK/Switzerland a Google consent form (UMP) appears before any ad loads (Settings → Privacy options).
Subscription (the app store's billing system). The Pro weekly subscription and its 7-day free trial are processed by the app store; we don't receive your payment details.
Install attribution (IST7). At first launch the app reads the Google Play install referrer. Only if the install link carries the tag utm_source=ist7 (a creator link), the app then sends advertising revenue events and confirmed purchase events to our attribution service IST7 (ist7.com), linked to a random installation identifier generated by the app. No personal identifier is sent (no advertising ID, no Android ID, no email address) and no purchase amount. If the app was not installed from such a link, nothing is sent. You can turn this measurement off in Settings; turning it off erases the identifier.
Diagnostics. The ads SDK may collect crash/performance data.
Children. For users 13+, not directed to children under 13.
Data deletion. There is no account to delete. Everything the app stores stays on your device and is removed when you uninstall it. For anything else, including advertising identifiers, see how to delete your data.
Data retention / Conservation des données. Data stored on your device (if any) is retained for the duration of the app installation and is permanently deleted when you uninstall the app. Apart from the install attribution described above (only for installs coming from a creator link), no user data is transmitted to or retained on our servers. / Les données stockées sur votre appareil (le cas échéant) sont conservées pendant la durée d'installation et définitivement supprimées lors de la désinstallation. Hormis l'attribution d'installation décrite ci-dessus (uniquement pour les installations issues d'un lien de créateur), aucune donnée utilisateur n'est transmise à nos serveurs.
