Privacy Policy
Last updated: June 4, 2026
Welcome to GraceSong AI (the "App"). We respect your privacy and are committed to protecting it.
1. Information We Collect
The App and our website may collect limited personal and technical information needed to provide core functionality.
Information you provide:
- Email address when you subscribe on our website (for billing, receipt, and linking your subscription to the App).
- User content such as lyrics text and optional voice recordings used for transcription and song generation.
- Optional push notification permission on your device.
We do not use email-and-password registration in the App. We do not require you to create or store an app login password.
Account and identity (Firebase Authentication):
- We use Google Firebase Authentication to assign a unique user identifier to your account.
- Your email (from web checkout or prior account linking) is associated with that identifier in our backend (Firestore) to store subscription status, generated songs metadata, and app settings.
- Sign-in to the App after a web purchase uses secure, short-lived tokens and install-matching signals—not a reusable password.
Install and activation (web to app):
- When you tap Download after checkout, we may record limited device signals (such as screen size, time zone, language, and a pseudonymous install intent) to help match your web purchase to your App install. We do not use this for unrelated profiling.
Automatically collected:
- Device and diagnostics data (app version, device model, OS version, crash logs).
- Basic usage data (feature usage, interactions, timestamps).
- Purchase and subscription state via Apple App Store / Google Play, Stripe (website), and RevenueCat.
- Push notification token (FCM) if you allow notifications, used only to deliver App-related messages.
- Attribution and analytics data via AppsFlyer, including advertising attribution, marketing measurement, and campaign performance analysis.
2. Push Notifications
The App may send push notifications for reminders, updates, and product messages.
You can disable notifications at any time in your device settings.
3. Purchases and Payments
Premium access is available via auto-renewable subscriptions:
- Weekly Subscription: $6.99 USD/week, with a 3-day free trial for first-time eligible users where offered.
- Yearly Subscription: $99.99 USD/year (where offered in the App).
Actual prices may vary by country/region, local currency, taxes, and store pricing rules. Final price is shown before purchase confirmation.
Payments on the website are processed by Stripe. In-app purchases are processed by Apple App Store / Google Play. We do not directly collect or store full payment card details.
Subscription status and purchase entitlement are managed via RevenueCat and our backend (Firebase / Firestore). RevenueCat may process pseudonymous user identifiers, purchase metadata, and limited device-level data for purchase validation, fraud prevention, analytics, and service reliability.
4. How Audio Data Is Stored
- Generated songs are stored on server-side infrastructure / generation provider systems.
- In the App library, we store references (audio_url) and metadata.
- A full audio file is saved locally on your device only when you explicitly choose Download or Share.
- Voice recordings for transcription are processed for functionality and are not retained longer than necessary for service operation.
5. Data Security
We use industry-standard safeguards, including encryption in transit and access controls, to protect data.
No method of transmission or storage is 100% secure.
6. Sharing Your Information
We do not sell your personal data.
We may share limited data with service providers strictly to operate the App and website, including:
- Google Firebase (Authentication, Firestore database, Cloud Messaging for push notifications, and related infrastructure)
- Stripe (website payments)
- AI, transcription, and song generation providers
- Infrastructure, analytics, and monitoring providers
- RevenueCat for subscription state management
- AppsFlyer for analytics, fraud prevention, advertising attribution, and marketing performance measurement
- Authorities where required by law
7. Your Rights
Depending on your jurisdiction, you may have rights to access, correct, delete, restrict, or port your data, and to withdraw consent where applicable.
To exercise your rights, contact us at info@maverix.agency.
8. Children's Privacy
The App is not intended for children under 13.
We do not knowingly collect personal data from children under 13.
9. Third-Party Services
The App integrates with third-party services such as AI generation/transcription providers, RevenueCat, and AppsFlyer.
These services may process data under their own terms and privacy policies.
10. AppsFlyer Attribution and Tracking
We use AppsFlyer to measure installs, campaign performance, and in-app events.
AppsFlyer may process device identifiers, attribution metadata, and event data for analytics, fraud prevention, advertising attribution, and marketing performance measurement.
Tracking is used for advertising attribution and marketing performance measurement.
This data is processed in a pseudonymous or aggregated manner and is not directly linked to personally identifiable user data.
Where required by applicable law (including on iOS), tracking is only performed where user consent has been granted.
11. International Data Transfers
Your data may be processed in countries other than your country of residence.
Where required, we apply appropriate safeguards under applicable data protection laws.
12. Changes to This Privacy Policy
We may update this Privacy Policy from time to time.
Updates become effective when posted in the App or on our website.
