HSK AI processes only the information needed to provide learning, account, security and subscription features.
Account identifiers from Telegram and, when you connect them, Google or Apple; your in-app display name and avatar choice; course progress, XP, streaks, mistakes, learning settings, subscription state and service diagnostics.
Provider subject identifiers are stored as keyed hashes. A provider may also supply an email address for display and account-security purposes. Email is not used to merge unrelated accounts.
Microphone permission is requested only when you use pronunciation or AI Voice. Audio you submit may be sent to HSK AI servers and service providers solely to transcribe, score or answer that voice interaction.
The Android app asks for notification permission only for study reminders. You can turn reminders off in HSK AI settings or revoke permissions in Android settings.
We do not sell personal data. Data may be processed by infrastructure, authentication, analytics or AI service providers only as needed to operate HSK AI, protect the service, or comply with law.
You can disconnect optional sign-in methods, change your app profile, sign out, revoke device permissions, and request deletion of your account and associated data.
Authentication tokens are protected and sensitive provider identifiers are not exposed in public leaderboard data. No system can guarantee absolute security; HSK AI limits access and data exposure by design.
