Privacy Policy

Last updated: 7 November 2026

This privacy policy applies to the Lumina Chronos app for iPhone and iPad (the “App”) published by Alben Risdev (the “Developer”).

Summary

The App does not require an account, and the Developer does not receive any personal information from it. From version 1.2.0 the App is free and shows banner ads provided by Google AdMob. Google may collect and use some information to show those ads, as described below. The App has no analytics of its own, and it does not sell data.

Data the App stores on your device

• Timer settings: focus and break durations, rounds per cycle, sound volume, vibration, countdown ticker, auto-start breaks, background animation, pause on minimize and orientation, stored with UserDefaults.
• Session state: the current phase, remaining time and round, so the timer survives the app being backgrounded or closed by the system.
• Counters: completed rounds and sessions. They are used for the round display, to decide when the banner ad appears, and to show Apple’s review prompt once.

This data is stored only on your device and the Developer never receives it. Deleting the App removes it.

Advertising (Google AdMob)

The App uses the Google Mobile Ads SDK to show a banner ad at the top of the timer screen during every third round. Google, as the ad provider, may collect and use:

• your device’s advertising identifier (IDFA), only if you allow tracking when asked;
• your IP address and an approximate location derived from it;
• device and app information, such as the device model, iOS version and app version;
• information about ads you are shown and how you interact with them.

Google uses this information to show, limit and measure ads, and may show personalised ads where your choices allow it. Google’s own handling of this data is described in its privacy policy at policies.google.com/privacy, and in how Google uses information from sites or apps that use its services.

Your choices. If you are in the United Kingdom, the European Economic Area or Switzerland, you will see a consent form from Google when you first open the App, and your answer controls whether personalised ads are used. You can change it at any time in the App under Settings → Ad privacy choices. The App then asks, through Apple’s App Tracking Transparency prompt, whether it may track you. If you choose Ask App Not to Track, the advertising identifier is not shared; you can change this later in iOS Settings → Privacy & Security → Tracking. Declining does not remove ads.

Permissions the App requests

• Tracking (App Tracking Transparency): optional, as described above.
• Notifications: requested the first time you leave a running timer in the background with Pause on Minimize turned off, so the App can tell you when the session ends. These are local notifications scheduled on your device; nothing is sent to a server.

The App does not access your contacts, calendar, precise location, microphone, camera, photos or health data. Haptic cues use the standard haptics APIs, which need no permission.

What the App does not do

• No accounts, iCloud sync or servers run by the Developer.
• No analytics or crash-reporting SDKs from the Developer.
• No in-app purchases.
• No selling of personal data.

Children

The App is intended for adults and is not directed at children. It does not knowingly collect personal information from children.
