Privacy Policy

Last updated: February 3, 2026

        Summary: Altarium is designed with privacy first. Your data is stored locally on your device and
        securely backed up to the cloud to prevent data loss. We don't use analytics or advertising. We use crash
        reporting to improve app stability.
      

1. Information We Collect And Store

Altarium stores your data locally on your device and backs it up securely to our servers (Firebase). This allows you to:

Recover your account if you lose your device
Participate in group statistics (if you join a group)

We do not collect personal identifiers like email addresses or phone numbers. Your account is anonymous and identified by a unique ID.

2. Data Storage

All your service records, badges, and preferences are stored locally and backed up to Firebase Firestore. This data is:

Encrypted in transit and at rest
Used solely for providing the App's features (backup & groups)
Deleted when you request deletion or delete your account

Account Recovery: Altarium generates a recovery code that allows you to restore your account on a new device. This code is stored securely in Firebase and linked to your anonymous account ID.

3. Feedback

If you submit feedback through the app, we store your message and optionally your contact email (if provided) in Firebase Firestore. This is used solely to respond to your feedback and improve the app.

4. In-App Purchases

When you make a purchase (e.g., creating a group), we verify the transaction with Apple or Google and store a record of the purchase linked to your anonymous account ID. We do not have access to your payment details.

5. Optional Group Feature

If you choose to join a parish group (optional feature), only the following is shared within that group:

Your chosen display name (anonymous by default)
Your avatar selection
Your service counts per role

Group data is stored securely using Firebase Firestore and is only visible to members of your group.

6. Third-Party Services

Altarium uses the following services:

Firebase Firestore (Google): For secured cloud backup and optional group sync
Firebase Crashlytics (Google): For crash and error reporting to improve app stability. This collects device information, app state, and stack traces when errors occur
Apple App Store / Google Play: For in-app purchase verification

See Firebase Privacy Policy.

We do not use advertising networks or behavioral analytics.

7. Children's Privacy

Altarium is intended for users aged 9 and older. We do not knowingly collect personal information from anyone, including children under 13.

8. Data Deletion

To delete all your data, use the "Delete Account" feature in the app (Settings → Delete Account). This removes all your data from our servers including backups, group memberships, and purchase records.

Simply uninstalling the app removes local data but does not delete your cloud data.

9. Changes to This Policy

We may update this Privacy Policy occasionally. Any changes will be posted on this page with an updated revision date.
