Privacy Policy

Kognit is your second brain inside Chrome. This policy explains what data the extension handles, where it lives, and the choices you have. In short: your library stays on your device.

Last updated: 3 July 2026

The short version

  • Your saved pages, notes, tags, and collections are stored locally in your browser.
  • No account is required to use the free features.
  • AI features run through your own API key — we don't proxy or store your prompts.
  • We do not sell your data or use it for advertising.
  • Cloud Sync is optional and off unless you turn it on.

Data we handle

Kognit only processes the data needed to save and organize the pages you choose to capture.

Website content

When you save a page or ask the AI assistant to read it, we capture the page URL, title, favicon, and a text excerpt so you can find and revisit it later.

Your content

Notes, tags, and collections that you create are stored so your library stays organized.

Browsing history (Pro, optional)

If you enable Auto-save or History Intelligence, recently visited pages are added to your library. This is processed locally and only when you turn the feature on.

API key

If you use AI features, your Groq or Google Gemini API key is stored locally on your device and sent only to that provider to fulfill your request.

We do not collect your name, email, passwords, financial details, health data, location, or personal messages.

Where your data is stored

Kognit is local-first. Your library lives in your browser's local storage on your own device. We cannot see it.

If you enable Cloud Sync (a Pro feature), your library is encrypted in transit and synced to our servers only so it can be mirrored across your own devices. You can disable sync and delete synced data at any time.

The on-page AI assistant

The AI assistant uses a provider key that you supply (Groq or Google Gemini). When you ask it to summarize or explain a page, the relevant page text is sent directly from your browser to that provider to generate a response.

We do not run our own AI proxy, and we do not store your prompts or the AI's responses on our servers. Your use of the AI provider is also subject to that provider's own privacy policy.

Why we request permissions

Each Chrome permission maps to a specific feature:

PermissionUsed for
storageSave your library and settings locally.
sidePanelShow your library and the AI reader.
contextMenusRight-click to save a page or link.
activeTab / scriptingCapture the current page and show the assistant, on your action.
tabsRead the URL and title of the page you're saving.
alarmsRun background clean-up and sync checks.
historyOptional Auto-save and History Intelligence.
notificationsInform you about saves, sync, and limits.
host accessLet you save and read any page you visit.

Sharing and selling

  • We do not sell or transfer your data to third parties, outside the limited use cases allowed by Chrome Web Store policy.
  • We do not use your data for purposes unrelated to Kognit's single purpose.
  • We do not use your data to determine creditworthiness or for lending.

The only external services that receive data are the AI provider you configure and, if you enable it, our optional Cloud Sync — both strictly to deliver features you asked for.

Your choices and control

Because your data is local, you're always in control:

  • Delete any saved item, note, or collection at any time inside the extension.
  • Clear your entire library from the extension settings.
  • Remove your API key to disable AI features.
  • Uninstalling the extension removes all locally stored data.
  • Turn off Cloud Sync to stop syncing and delete synced copies.

Kognit is not directed at children under 13, and we do not knowingly collect their data.
