Privacy Policy
Last updated: July 2026
1. Our approach
Sonalog (the "App") respects your privacy to the fullest extent. All data you enter or record in the App — household members, stock items, expiry dates, emergency contacts, meeting place, go-bag items and so on — is stored only on your device.
2. Information we collect
The App does not collect or transmit any data, including personal information. Neither the developer nor any third party can access your data. No account is required.
3. Network
The App works fully offline. Network activity only occurs when processing in-app purchases (buying or restoring Full Access) through the App Store, which is handled via Apple's StoreKit. Purchase processing follows Apple's privacy policy.
4. Notifications
Expiry alerts for your stock use on-device local notifications. Their contents are never sent externally.
5. Third-party services
The App uses no analytics SDKs, advertising SDKs or tracking of any kind.
6. Deleting data
Deleting the App also deletes all data stored on your device.
7. Contact
For questions about this policy, contact support@freetokyolabs.com.
How the Android version handles your data
The following describes the Android version (Android 9.0 and later). Everything above applies to iOS; only the points below differ on Android.
Your records are stored in a local database (Room) on your device. They are never sent to the developer's servers.
Both cloud backup and device-to-device transfer are disabled (allowBackup="false" plus data_extraction_rules.xml). To move to a new device, export a backup yourself from inside the app.
The only external service used is Google Play Billing (purchases). Google processes all payments; card details never reach the developer.
The only device permission the app requests is showing notifications. It is asked for only when you use the matching feature, and declining leaves the rest of the app usable.
Uninstalling the app deletes the data on your device. With backup and transfer disabled, no copy remains outside it.
Controller, contact and your rights
This app is provided by Freetokyo Labs, which acts as the data controller. For any question about this policy or about personal data, contact support@freetokyolabs.com. We normally reply within five business days.
If you are in the EU, the EEA or the UK, the GDPR gives you the right to access, rectify, erase, restrict and port your personal data, to withdraw consent and to object to processing. You may also lodge a complaint with your national supervisory authority.
If you are a California resident, the CCPA/CPRA gives you the right to know, delete and correct the personal information collected about you, and to opt out of its sale or sharing. We do not sell or share personal information.
Where this app stores data only on your device, we have no access to it, so most of these rights are exercised directly on the device: delete or export inside the app, or delete the app. We will still answer any request you send us.
Retention: on-device data is kept until you delete it or remove the app. Support emails are deleted 24 months after the request is closed.
