Nothing. ChatSave has no server and no analytics. It does not collect, store or transmit your conversations, your account details or your browsing activity.
PDF, Word, Markdown, HTML, text and JSON files are generated inside your browser and saved to your computer. They are never uploaded.
Notion: if you paste a Notion integration token, ChatSave stores it in your browser's extension storage and sends the chat you choose to Notion's API only when you click Sync to Notion.
Fylo: if you connect a Fylo account, ChatSave stores an access token in your browser's extension storage and sends the chat or code you choose to Fylo only when you click Publish. You can disconnect at any time from the extension popup or from your Fylo dashboard.
ChatSave runs only on the AI chat sites it supports, plus api.notion.com and fylo.host for the optional connections above. It uses storage for your settings and identity for the Fylo sign-in flow.
