App identity.
This privacy policy applies to the app World Time Zone Converter (package name: com.play3rs.worldclock), published on Google Play under the developer name Play3rs by the legal entity Play3rs (contact: support@z-ax.com).
World Clock 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).
Cities, labels and groups. The cities you add, the labels you give them, your groups, your office hours and your display settings are stored only on your device. We never receive them. The app reads your phone's time zone to suggest a home city; it does not use your location.
Home screen widgets. The widgets show the cities you chose and are refreshed on your device. They send nothing.
Sharing and calendar. When you choose to send a time (as text) the app hands that text to the Android share sheet and to the app you pick. When you choose "Add to calendar" the app opens your phone's calendar screen with the meeting filled in; you decide whether to save it, and the app never reads your calendar. Nothing is sent to us.
Purchases (the app store's billing system). The Pro subscriptions (weekly with a 7-day free trial, or monthly), the one-time Pro purchase, the one-time ad removal and the one-time dials and themes pack 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.
