Privacy Policy
Effective date: July 27, 2026
The one-sentence version: your chat history lives only on your own phone; the current conversation is sent to an AI model only when you tap "Generate"; our servers relay but never store any chat content; there is no account system, so we don't know who you are.
1. What we process
- Chat text on screen: read via the Accessibility service you grant manually, and only the text already visible in the current chat screen. Reading happens only inside chat apps — other screens are never read or recorded. This text is kept locally on your phone (for the per-contact memory feature) and is never uploaded automatically.
- Generation requests: when you tap "Generate", the most recent messages of the current conversation are sent to an AI model to draft replies. With your own API key, the request goes directly from your phone to the model provider and never passes through us; with the membership channel, the request is relayed to the model through our server over an encrypted connection — relayed only, never stored, never used for anything else. HTTPS end to end.
- Screenshots (optional feature): only when the other side sends an image/sticker and you have configured a vision-capable model, the current chat screen is captured and sent to that model for understanding — never saved to disk, never shared with anyone else.
- Device identifier: an anonymous number derived by hashing device information, used for free-allowance counting and activation-code binding. It cannot be traced back to your identity.
- Anonymous usage statistics: which of the three suggestions you picked, or that you tapped "Refresh" — just these actions, containing no chat content whatsoever, used to improve the product.
2. What we never do
- We never store your chat content; server logs do not record request bodies;
- There is no account system — we collect no phone number, email, contacts, or location;
- We never sell or share your data with any third party;
- We never send messages on your behalf in the background — sending is always your own tap.
3. Third-party model providers
Replies are generated by AI models (such as DeepSeek, OpenRouter and the models it connects to). Conversation content sent to a model is governed by that provider's own privacy policy. When you use your own API key, your relationship is directly with the model provider.
4. Permissions
- Accessibility service: reads chat text and fills your chosen reply into the input box. Can be turned off in system settings at any time.
- Display over other apps: shows the floating bubble and the reply panel. Can be turned off at any time.
- Notifications: a persistent notification showing that the floating bubble is running.
5. Data retention & deletion
Local chat memory can be deleted anytime in the app under "Chat history"; uninstalling the app erases everything. Our server keeps only activation-code bindings and usage counts; email us to have those deleted.
