This data is aggregated and anonymous and used solely to improve app performance and stability.
d. AI Chat Messages
When you use the AI chat feature:
- You do not need to create an account. Instead, a random internal identifier is generated to link your chat sessions.
- Chat messages are stored securely on our servers and linked only to this identifier.
- If you delete a chat, all associated messages are permanently removed.
- Inactive chats will be automatically deleted after 90 days.
- Chat messages are private and not accessed by anyone else. The only exception is if you explicitly report a message as inappropriate. In that case, the reported message and the three preceding messages may be reviewed by our moderation team. If inappropriate content is confirmed, the AI model will be adjusted accordingly.
2. Data Sharing
We do not sell, rent, or share your personal information with any third parties.
Data is only shared in the following limited circumstances:
- With Firebase services for analytics and crash reporting (as outlined above)

stored locally on your device.
We take appropriate measures to ensure any data processed for search
functionality or crash reporting is handled securely.
