Privacy Policy
Last updated: July 2026
Zaicho (the “App”) is an iOS app provided by freetokyo (“we”). We designed the App with your privacy as the top priority.
1. Information we collect
The App collects no personal or asset information. All data — including any names, contacts, account details and asset entries — is stored only on your device. We have no access to it.
2. No external transmission or sharing
The App does not send your data to any external server. It has no account linking, cloud sync or sign-up, and we never share or sell data to third parties. The App works fully in Airplane Mode.
3. Tracking and ads
The App does not use behavioral tracking, advertising identifiers (IDFA), or analytics SDKs.
4. Storage and backup
Data is stored on your device. If you enable iCloud Backup, app data may be included in your device backup, but that is your own Apple-managed backup and we cannot access it. CSV and PDF exports happen only when you initiate them, to a destination you choose.
5. Purchases
In-app purchases (Full Access) are processed by Apple’s App Store. We do not receive or store payment or card information.
6. Contact
For questions about this policy, contact freetokyo2020@yahoo.co.jp.
Controller, contact and your rights
This app is provided by freetokyo, an independent developer, who acts as the data controller. For any question about this policy or about personal data, contact freetokyo2020@yahoo.co.jp. 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.
