Effective date: November 5, 2026 Applies to: the Super DeepSeek browser extension for Chrome and Firefox (version 1.0.0 and later)
Super DeepSeek adds projects, personas, skills, memory, scheduled tasks, voice input, exports and organization tools to DeepSeek. It was built to keep your data with you.
| Data | Where it is kept |
|---|---|
| Settings and feature switches | Your browser (storage.local), and your browser’s sync storage |
| Your instructions, custom personas and skills, memory notes | Your browser, and your browser’s sync storage |
| Scheduled tasks | Your browser, and your browser’s sync storage |
| Folders, tags, archive, Recycle bin, starred replies | Your browser; synced when they fit in the sync storage limit |
| Projects (name, color, instructions, chat list) | Your browser; synced when they fit, without file contents |
| Project files you add (text extracted from PDF, Word, Excel, text files) | Your browser only |
| Replies saved for the task audio player | Your browser only |
| Backup files you export | A file you download and keep yourself |
Browser sync storage is part of your own Chrome or Firefox account and is handled by Google or Mozilla under their privacy policies. The developer cannot access it. If you turn browser sync off, everything stays on your device only.
To do its work, the extension talks only to chat.deepseek.com, using the session you are already signed in with, exactly as the DeepSeek website does:
Whatever is sent to DeepSeek is governed by DeepSeek’s own privacy policy. Super DeepSeek does not send your data to any other website.
The microphone button uses your browser’s built-in speech recognition. In Chrome, the browser sends the audio to Google to turn it into text; Super DeepSeek never receives or stores the audio. Voice input only listens between your clicks on the microphone button (start and stop), and only after you allow microphone access. (Firefox does not offer this feature, so the button is hidden there.)
Reading task replies aloud uses the voices installed in your browser and operating system. No audio is recorded or uploaded by the extension.
HTML, SVG and diagram previews and the Python runner work inside your browser. Previews run in an isolated page that cannot reach DeepSeek, the extension or your account. Python (Pyodide with numpy, pandas and matplotlib) is bundled in the extension and runs offline. Nothing is sent anywhere.
