Hissin Privacy Policy
This policy explains what data Hissin processes in the mobile app, why it is used, and what rights users have over their data.
Data we process
Account data: name, email, Apple/Google sign-in provider ID, legal consent records, and subscription status.
App content: chat messages, user-visible memory notes, reminders, check-in answers, AI memory preference, profile preferences, and avatar usage records.
Device permissions: camera/photo access for profile photos, microphone/camera access for live avatar, notification permission, and health data access only if the user grants it.
During live avatar sessions, microphone data is processed in real time to run the live call, recognize speech, and generate real-time AI avatar responses.
Hissin does not permanently store raw audio recordings from live avatar sessions on its own servers. However, text/transcripts generated from speech may be stored for chat history, security, personalization, and AI memory features.
Why we use data
To create accounts, manage sessions, provide app features, run reminders and memory records.
To personalize AI chat and avatar experiences only within the user's permitted scope, prevent misuse, verify subscription status, and keep required legal records.
When explicitly permitted, step count and heart rate data are used for movement reminders, calming suggestions, and avatar support.
AI memory is optional and may include user-visible notes, reminder content, limited context derived from chat history, and emotional or relationship follow-up signals.
When AI memory is turned off under Profile > Permissions, new personal memory or emotional/relationship follow-up signals are not created, and past context is not used in future chats.
Sensitive data and crisis content
Hissin does not provide medical advice, diagnosis, treatment, or crisis support.
Content about depression risk, suicidal ideation, or serious mental-health labels is not continued as normal chat and is not saved as a note, reminder, or AI memory record.
Sensitive data is retained only to the minimum extent needed for the relevant feature; users can initiate deletion of app data through account deletion.
Third-party services
Hissin may use infrastructure providers such as OpenAI, LiveKit, Simli, Render, RevenueCat, Apple, and Google for authentication, subscription management, AI responses, speech processing, live avatar experiences, and hosting.
Only the data required to run the relevant feature may be shared, such as account/session information, subscription verification data, avatar session information, audio/data streams, speech text, user name, technical usage data, or security records.
Hissin does not use health data, audio data, chat content, or AI memory for advertising, tracking, marketing, or data sale.
User rights
Users can request privacy actions and account deletion from the Privacy Center or by contacting support.
Notification, camera, microphone, photo, and health permissions can be managed from device settings; AI memory can be turned off under Profile > Permissions and deleted from the Privacy Center.
Privacy requests can be sent to info@hissin.app.
