Third-Party SDK List
App identifiers: Android package ai.infinityquest.vocay.frontend, iOS Bundle ID ai.infinityquest.vocay
Last updated: August 3, 2026
1. Overview
To enable Vocay App features and ensure stable operation, we integrate third-party software development kits (SDKs). We monitor SDK security and use their capabilities only to the extent necessary for the corresponding features.
Please note:
- Actual data fields collected may vary by SDK version and enabled modules (e.g., IDFA/OAID collection). Refer to the app version on your device and each SDK provider's official documentation.
- The SDKs listed below are integrated only in native iOS/Android clients. The web build (via
expo export) does not load native ad-attribution SDKs; product analytics on web primarily uses PostHog and other web-compatible methods. - We initialize SDKs that collect personal information after you agree to the Privacy Policy, in line with each provider's compliance requirements. You may disable ad tracking identifiers in system settings or turn off personalization options in the app where available.
- Channels such as Xiaohongshu Juguang have no official client SDK. We capture
click_idvia deep links and report conversions through our own servers; this is not listed separately below. See the "Advertising & Attribution" section of our Privacy Policy.
