2. App Tracking Transparency (iOS)
On iOS 14.5 and later, the App will request your permission to track your activity across other apps and websites via Apple's App Tracking Transparency (ATT) framework. You may allow or deny this request at any time.
- 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.
