2. App Tracking Transparency (iOS)

- If you allow tracking, personalized ads may be shown based on your activity.
- If you deny tracking, non-personalized ads will be shown instead.
You can change your preference at any time in:
Settings → Privacy & Security → Tracking → BlastChain

3. Advertising and Consent (GDPR)
If you are located in the European Economic Area (EEA), the United Kingdom, or other regions where consent-based advertising laws apply, the App will present a consent form powered by Google's User Messaging Platform (UMP) before displaying any personalized ads. You may withdraw or update your consent at any time by reinstalling the App.
