This Privacy Policy explains how Lume ("we", "us", or "our") collects, uses, and protects information when you use our mobile application (the "App").
By using Lume, you acknowledge that you have read this Privacy Policy.
Lume stores the information necessary for its core functionality directly on your device. This information is not uploaded to our servers.
Depending on how you use the App, this may include:
This data remains on your device until you delete it, clear the App's storage, or uninstall the App.
To help improve the App and diagnose technical issues, Lume uses Google Firebase services.
These services may collect technical information such as:
This information helps us understand how the App performs and identify software issues. We do not use this information to personally identify users.
We use the collected information to:
Lume requires certain Android permissions to provide its functionality.
Used by the App Blocker feature to determine whether a blocked application is currently open.
This processing occurs entirely on your device. Information about which apps you use is never uploaded to us.
Required to display the blocking screen when you attempt to open a blocked application during an active focus session.
Allows the App Blocker to continue operating reliably while a focus session is active. The special-use foreground service type is required by Android for services that monitor foreground app usage.
Required to connect to Firebase services for crash reporting, analytics, and App Check security verification. No personal data stored on your device is transmitted through this connection.
Used to display:
Notifications can be disabled at any time through your device settings.
Allows scheduled focus sessions to start at the precise times you choose.
Used for optional haptic feedback when focus sessions finish or blocked apps are intercepted.
Allows scheduled sessions and reminders to be restored after your device restarts.
Lume currently uses the following third-party services:
Purpose: Anonymous usage analytics to help us understand how the App is used and improve future updates.
Purpose: Crash reporting and diagnostics to help identify and fix software issues.
Purpose: Helps verify that requests originate from authentic versions of Lume and protects our Firebase services against abuse.
These services are provided by Google and may process information in accordance with Google's Privacy Policy.
We do not sell your personal information.
We do not share the information stored locally on your device with third parties.
Anonymous diagnostic and analytics information is processed by Google Firebase solely to provide analytics, crash reporting, and application security services.
We may also disclose information where required by law or to comply with legal obligations.
Google Firebase may process information on servers located outside your country of residence, including the United States and other countries where Google operates.
Where required by applicable law, these transfers are protected by appropriate safeguards implemented by Google.
Information stored locally on your device remains available until you:
Analytics and diagnostic information is retained according to Google's applicable retention policies.
We take appropriate technical measures to help protect information, including:
While we take reasonable steps to protect information, no method of electronic transmission or storage is completely secure.
Depending on your location, including if you are located in the European Economic Area (EEA), United Kingdom, or other jurisdictions with applicable privacy laws, you may have rights including:

However, some third-party services used by the App, such as Google Firebase Analytics, may use similar technologies (such as device identifiers) to collect analytics and improve the App. These technologies are used only for the purposes described in this Privacy Policy.
We may update this Privacy Policy from time to time.
