Your privacy

This policy explains how CitizenCH handles information in the app and on this website. For privacy questions, contact support.citizench@lumenlabs.ch.

At a glance: no account is required, your study progress and interview recordings are stored on your device, and we do not use advertising trackers. We use third-party services to provide updates and crash reporting.

Your study data

Your settings, study progress, answers, bookmarks, test history, interview notes, and recordings are stored on your device. CitizenCH does not upload this material for cloud syncing, and there is no account-based sync between devices.

Your device's backup settings may include app data in a device or cloud backup.

App services and crash reports

We use Google Firebase to deliver question updates, manage app settings, protect our services, and investigate crashes. Firebase processes technical information such as app version, device and operating-system information, installation identifiers, and crash reports.

Crash reporting through Firebase Crashlytics is enabled automatically. The app currently has no setting to turn it off. Crash reports may be sent when your device connects to the internet.

We do not use Google Analytics or advertising trackers. Information processed by our service providers may be handled outside Switzerland. See Google's Firebase privacy information for details about its processing and retention practices.

Location and microphone

Location is optional. It helps sort municipalities by distance from you. You can also select it manually. CitizenCH does not track your location in the background.
The microphone is optional. It lets you record interview practice answers when you choose. Recordings stay in the app's local storage; the app does not send them to an AI service.

You can change location and microphone permissions in your device settings.

Contacting support

If you email us, we receive your email address, message, and anything you choose to attach. We use this information to respond and investigate the problem. Please avoid sending identity documents, private notes, or recordings.

We may ask for a support ID to enable troubleshooting information in your app. This ID identifies an app installation, not an account. Sharing it by email links it to your support request. It does not give us remote control of your device. The troubleshooting panel does not turn crash reporting on or off.

Keeping and deleting information

Study history: detailed activity older than 90 days is periodically replaced with daily summaries. Summary statistics remain on your device.
Reset Progress: this clears study and test progress. It does not delete interview notes, recordings, interview completion, or your settings. You can clear notes and delete recordings in interview preparation.
Removing the app: this generally removes its local data. Device backups may retain copies. Reinstalling may lose your progress.
Service and support records: removing the app or resetting progress does not delete crash reports held by providers or emails sent to support. Provider retention varies by service; contact us about information held in connection with your support request.

This website

This website has no advertising or analytics trackers. It is hosted by GitHub Pages, which processes technical information such as IP addresses and page requests to deliver the site. Read the GitHub privacy statement. App stores and beta-testing platforms handle information under their own privacy policies.

Your choices and requests

For questions or requests to access, correct, or delete information held by the developer, email support.citizench@lumenlabs.ch. We will explain the options available for your request under applicable law.

We will update this policy when our practices change. For information about educational use, see the Disclaimer.
