Account information and Google sign-inProgress on your deviceStorage, backups and technical dataService providers and your choicesDeleting your account and dataContact and privacy requestsKörkortPass is provided by Zeta Code. This policy explains how account information and study progress are handled in the app and on our account website.
Account information and Google sign-in
We use Google Firebase Authentication to create and manage your KörkortPass sign-in account. It processes your account ID, e-mail address, authentication credentials and sign-in activity. If you choose Google sign-in, it also processes your Google account identifier and available profile name and photo. Your Google password is handled by Google; KörkortPass does not receive it. We use this information to authenticate you, display your account and protect account operations.
Progress on your device
Reading progress, reading positions, exercise answers and exercise history are stored locally on your device or in your browser. They are not uploaded to a KörkortPass cloud progress database. Progress on a device is shared by accounts using that installation. Signing out keeps this local progress; Reset progress clears it without deleting your account.
Storage, backups and technical data
The app and website use local storage for sign-in sessions, settings and recovery of interrupted account deletion. The account website keeps credentials only in page memory and stores a limited deletion-status record, without passwords or tokens, in this browser until you dismiss it. Your device or browser may retain app data in backups according to its settings. Exported progress files remain wherever you save or share them. Firebase Authentication, Firebase Hosting and Google sign-in receive technical request information such as IP addresses, browser or device information and service activity to deliver and secure their services. Their processing is governed by the applicable Google and Firebase terms and privacy information.
Deleting your account and data
In the app, open Your data → Delete account. Successful deletion removes your Firebase Authentication account and clears study progress in that installation. You can also delete your account on our website without installing the app: verify ownership, review the effects and confirm deletion. The website cannot erase progress stored on other devices or in the study app browser, device backups or exported files. Clear app data on those devices and remove backups or exports you control if you want to erase them. Deleting your KörkortPass account does not delete your Google account. Account information remains in Firebase Authentication until the account is deleted. We do not maintain a separate account archive; service-provider security logs and backups are subject to their own retention practices. We do not promise immediate removal from those systems.
Contact and privacy requests
For account help or requests to access, correct or delete personal information, contact Zeta Code at zeta.code.dev@gmail.com. We may ask you to verify ownership before acting on a request. Do not send your password or sign-in tokens. You may also raise concerns with your local data protection authority. We will update this policy when our data practices change.
