Privacy Policy
Last updated: April 8, 2026
This privacy policy applies to all mobile applications published by Isako AS ("we", "us", "our"), including but not limited to Lettergeist, and any future apps published under the same developer account.
Data We Collect
Our apps do not collect, store, or transmit any personal data. We do not require accounts, logins, or registration of any kind.
All game data (progress, settings, statistics) is stored locally on your device and is never sent to any server. All functionality works fully offline.
This app is compliant with the General Data Protection Regulation (GDPR) and Norwegian personal data law (personopplysningsloven). Since no personal data is collected or processed, no legal basis for processing is required.
Third-Party Services
Our apps do not use third-party analytics, tracking, or advertising SDKs.
If a future update introduces advertising, this policy will be updated to reflect the data practices of the ad provider.
Children's Privacy
Our apps do not knowingly collect any personal information from children. Since we do not collect data from any user, our apps are safe for all ages.
Permissions
Our apps may request the following permissions:
- Notifications — To send optional daily reminders. No data leaves your device.
Data Retention
Since we do not collect any data, there is nothing to retain. Uninstalling the app removes all locally stored data from your device.
Changes to This Policy
We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
