Privacy Policy

ChangeDA — Currency & Gold Rates Tracker · Last updated: April 12, 2026

1. Overview

ChangeDA ("the App") is a currency and gold rates tracker for the Algerian parallel market. This policy explains what data we collect, why, and how it is handled. We are committed to protecting your privacy.

2. Data We Collect

Data Type	Purpose	Shared With
Device Identifier (IDFA)	Personalized advertising and ad attribution (with your consent)	Google AdMob, Meta Audience Network
App usage & interaction data	Analytics, app improvement	Firebase Analytics, UXCam
Session replay analytics (schematic recordings)	Understand navigation flows, taps, and UX friction	UXCam
Crash logs & diagnostics	Stability monitoring, bug fixing	Firebase Crashlytics, UXCam
Push notification token	Sending rate change alerts	Firebase Cloud Messaging
Purchase history	Premium access management and ad removal	Adapty (via Apple StoreKit)

ChangeDA uses UXCam in schematic mode for session replay analytics. This captures the app's structure and interaction patterns rather than raw pixel-perfect screen recordings.

3. Advertising & Tracking

The App displays ads through Google AdMob and mediated partners that may include Meta Audience Network. Before personalized advertising is enabled, the App asks for permission through Apple's App Tracking Transparency (ATT) framework.

• If you allow tracking: Your device advertising identifier (IDFA) may be shared with Google and mediated ad partners such as Meta to serve ads relevant to your interests.
• If you deny tracking: You will still see ads, but they will not be personalized. No cross-app tracking occurs.

You can change your tracking preference at any time in Settings > Privacy & Security > Tracking on your device.

4. Push Notifications

The App may request permission to send push notifications for rate change alerts. Your device token is registered with Firebase Cloud Messaging (FCM) solely for delivering these notifications. You can disable notifications at any time in your device settings.

5. In-App Purchases & Subscriptions

The App may offer optional one-time purchases or auto-renewable subscriptions managed through Adapty and Apple's StoreKit. Purchase transactions are processed by Apple. Adapty receives transaction-related data needed to manage premium access and entitlements. No payment details (credit card numbers, billing address) are collected or stored by us.

6. Third-Party Services

The App uses the following third-party services, each with their own privacy policies:

• Google AdMob — Advertising
• Meta Audience Network — Advertising mediation
• Firebase — Analytics, Crashlytics, Cloud Messaging, Firestore
• Adapty — Subscription management
• UXCam — Session replay analytics

7. Data Retention

Analytics, session replay, and crash data are retained according to the default retention periods of the providers we use, including Firebase and UXCam. Push notification tokens are retained as long as notifications remain enabled. We do not maintain user accounts or store personal information on our servers.

8. Children's Privacy

The App is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

9. Your Rights

You may:

• Opt out of personalized ads via device Settings > Privacy & Security > Tracking
• Disable push notifications via device Settings
• Request deletion of your data by contacting us

10. Changes to This Policy

We may update this policy from time to time. Changes will be reflected on this page with an updated date. Continued use of the App after changes constitutes acceptance.
