Privacy Policy
Effective date: 24 April 2026
This Privacy Policy describes how Nijo Studio ("we", "us", "our") handles information when you use our websites and mobile applications, including Heirloom (published on Google Play under the developer name "Nijo Studio"). By using our apps or site you agree to the handling of information as described here.
1. Information we handle
We try to collect as little as possible. What we do handle falls into these buckets:
- Photos you provide. Heirloom processes photos you pick from your device gallery or capture with the device camera, solely to deliver photo restoration results to you.
- Device & technical information. Anonymous technical data such as device model, OS version, app version, and crash logs to diagnose issues and improve stability.
- Account information. If you sign in or create an account for a particular service, we handle the identifiers you provide (such as email address).
- Purchase information. If you buy a subscription or in-app purchase through Google Play, Google provides us with a purchase token; we do not see or store your payment card details.
2. Camera and photo access
Heirloom requests camera and media-library permissions to let you take new photos or pick existing ones for restoration. These permissions are used only when you actively trigger the feature. Photos are not uploaded, shared, or retained except as strictly needed to produce the restored output, and are not used for advertising, profiling, or sold to any third party.
3. How we use information
- To provide the core functionality you requested (e.g., restoring a photo).
- To diagnose crashes and improve the quality of our apps.
- To process subscriptions and purchases.
- To respond to support requests you send us.
We do not sell personal information. We do not use your content to train third-party AI models.
4. Sharing
We share information only with service providers that help us operate — for example, Appwrite (self-hosted, operated by us) for backend storage, Google Play for distribution and billing, and crash-reporting tools. Each provider is bound by their own privacy and security terms. We do not share your information for marketing purposes.
5. Retention
Photos you submit for restoration are retained only for as long as needed to deliver the result, and then removed from our processing systems. Account data is retained while your account is active and deleted on request.
6. Your choices
- You can revoke camera or media permissions at any time from your device settings.
- You can request deletion of your account and any data we hold by emailing us at the address below.
- You can uninstall the app to stop any further on-device data collection.
7. Children
Our apps are not directed at children under 13, and we do not knowingly collect information from children under 13.
8. Changes to this policy
We may update this policy from time to time. Material changes will be reflected by updating the "Effective date" above. Continued use of our apps after changes means you accept the updated policy.
