Archegenos Privacy Policy

App: Archegenos (com.dreamingscientist.family_tree.proaccount). Effective date: 27 September 2026.

Archegenos is published by Vu Khac Muoi. For privacy questions, email apps.dreamingscientist@gmail.com.

1. Local family information

Your family tree, people, relationships, dates, places, notes, photographs, contact details, stories, settings and reminders are stored locally on your device. We do not operate a cloud database that stores or synchronizes this family information. Signing in and purchasing Pro do not upload it.

You are responsible for having authority to enter and share information about other people, particularly living people and minors. Local data is normally removed when you uninstall the app, subject to backups managed by your device or store account.

2. Permissions, files and sharing

The app uses contacts, camera, photos, notifications or files only when you choose a feature that needs them and grant permission. Selected contact information or photos are copied into the local family tree. Reminders are generated locally.

When you import, export, print or share a branch, person, image, message, report or PDF, you choose the file or destination. The receiving app, storage provider or person then handles that copy under their own terms. Nothing is shared automatically.

3. Optional account and linked sign-in methods

Firebase Authentication provides optional Sign in with Apple and Google Sign-In. Depending on the provider, Firebase may process a unique user ID, email address, name, profile photograph, sign-in provider, sign-in dates, IP address and device or browser information for authentication, security and abuse prevention. Apple may provide a private relay address when you choose Hide My Email.

You may link one Apple sign-in and one Google sign-in to the same Firebase user ID. Both methods then open the same Archegenos account and use the same Pro entitlement on supported iOS and Android devices. The app displays linked providers and their available email or Apple relay address. Users cannot unlink providers themselves; this helps prevent repeated transfer of Pro access between unrelated accounts.

Signing in never uploads your family tree. Each device still keeps its own local family data.

4. Archegenos Pro and RevenueCat

Pro is a one-time, non-consumable purchase processed by Apple or Google under their policies. RevenueCat validates purchases and manages the archegenos_pro_lifetime entitlement.

Legal basis: performing our contract with you and our legitimate interest in preventing purchase fraud.

5. Account-linking support

Signed-in Pro users can choose to open a support email draft when an Apple or Google account was linked by mistake. The draft automatically includes the Archegenos account ID (Firebase user ID), linked provider identifiers, available provider emails or Apple relay addresses, and space to identify the incorrect and intended replacement accounts. The user reviews and sends the message themselves; nothing is sent automatically.

We use this information only to identify the correct Firebase and RevenueCat customer, verify the request, provide support and prevent unauthorized entitlement transfers. Support correspondence is kept only as long as reasonably needed to resolve the request, prevent fraud and meet legal obligations.

7. Retention, deletion and rights

Local family information remains until you delete it, clear the app's data, uninstall the app or erase the device. Exported copies remain wherever you saved or shared them until deleted there.

Firebase account information remains while your account exists. You can delete the account in Settings; this does not delete your local family tree, Apple ID, Google account, exported files or store purchase record. Apple, Google and RevenueCat retain purchase and entitlement records as needed under their policies and applicable law.

Depending on where you live, you may have rights to access, correct, delete, restrict or receive personal information. Contact us to exercise those rights. EEA residents may also complain to their local data-protection authority.

8. Security, children and changes

Authentication and purchase information is transmitted using encrypted connections. Local data security depends on your device security. Protect your device and exported files. No storage or transmission method is completely secure.

Archegenos is intended for adults managing family history and is not directed to children under 13. Adults should take particular care with information about minors.

We may update this policy when the app or legal requirements change. The effective date identifies the current version.
