Backpack Battles

"We also use Firebase SDK and Apple ads attribution API for advertising attribution/measurement and optimization. They will collect personal data directly from users by themselves. Google Firebase (Ads Attribution/Measurement) personal data: advertising identifiers (e.g., GAID, IDFA); device identifiers (e.g., IDFV, OAID, Android ID); device information; network status; attribution and event signals."

The app integrates Firebase SDK and Apple Ads Attribution API that collect advertising identifiers, device identifiers, and event signals directly from users' devices for ad measurement and optimization, with the company disclaiming responsibility by calling these providers 'independent controllers.'

"Google Firebase (Ads Attribution/Measurement) personal data: advertising identifiers (e.g., GAID, IDFA); device identifiers (e.g., IDFV, OAID, Android ID); device information; network status; attribution and event signals. Purpose: Advertising attribution, advertising optimization on related Google products (e.g., Google Play)."

Firebase collects multiple advertising and device identifiers (GAID, IDFA, IDFV, OAID, Android ID) that can be used to track users across apps and services, explicitly for 'advertising optimization on related Google products.'

"We may update this Policy from time to time. We will notify you the updated Policy in the app or via other reasonable means before changes take effect. Your continued use of Backpack Battles after the effective date signifies acceptance of the updated Policy."

The company can change the privacy policy at will and treats continued use of the app as acceptance of new terms, with no mechanism for users to reject changes other than stopping use entirely.

"Apple Ads Attribution API personal data: advertising identifiers/signals (e.g., IDFA where permitted); device information; network status; iOS attribution signals. Google Firebase personal data: advertising identifiers (e.g., GAID, IDFA); device identifiers (e.g., IDFV, OAID, Android ID); device information; network status; attribution and event signals."

The app's integrated SDKs collect a broad range of device identifiers (GAID, IDFA, IDFV, OAID, Android ID), device information, and network status — beyond what a card-battling game's core functionality requires.
