# Privacy Policy for Synto

### 1. Data Collection

Synto collects no personal data. There are no accounts, no analytics, and no telemetry.

### 2. API Keys

Your API keys for OpenAI, Gemini, and Grok are stored locally on your device using `chrome.storage.local`. They are never sent to any server. They are only used to authenticate your requests directly to the AI provider you selected.

### 3. Page Content

When you extract a page, the Markdown conversion runs locally in your browser. When you click Ask AI, the resulting content is sent directly from your browser to the AI provider you selected (OpenAI, Google, or xAI) via their official APIs. Synto is not involved in that transfer and does not store the content.

### 4. Third-Party Services

By using Ask AI, you interact with third-party providers. Review their privacy policies:

- [OpenAI](https://openai.com/policies/privacy-policy/)
- [Google AI](https://ai.google.dev/gemini-api/terms)
- [xAI](https://x.ai/legal/privacy-policy/)

### 5. Open Source

Synto is open source. You can review the full code at [github.com/artttj/synto](https://github.com/artttj/synto). Report issues or questions in the [issue tracker](https://github.com/artttj/synto/issues).
