Privacy Policy for Cortex

Last Updated: January 2025

TL;DR

We don't collect anything. Your data never leaves your device.



The Long Version

What Data Do We Collect?

None. Zero. Nada. Zilch.

Cortex doesn't collect, store, transmit, or share any of your data. Period.

What About My Bookmarks?

Your bookmarks are stored locally on your device using your browser's storage API.

• ❌ Not sent to our servers (we don't have servers)
• ❌ Not sent to third parties
• ❌ Not analyzed or tracked
• ✅ 100% private, 100% yours

What About Analytics?

We don't use any.

No Google Analytics. No tracking pixels. No telemetry. No "anonymous usage data."

We literally cannot see:
- What you bookmark
- How many bookmarks you have
- Which themes you use
- How often you use Cortex
- Anything about you

What Permissions Does Cortex Use?

Storage Permission

Why: To save your bookmarks, categories, tags, and settings on your device.
Where: Your browser's local storage (never leaves your computer)

Bookmarks Permission

Why: To import bookmarks from your browser (only when you click "Sync Browser Bookmarks")
Where: Read from your browser, saved locally. Never transmitted anywhere.

Active Tab Permission

Why: To auto-fill the current page URL when adding a bookmark
Where: Only used when you manually add a bookmark. Never tracked.

Context Menu Permission

Why: To add "Add to Cortex" option when you right-click
Where: Creates a menu item. Doesn't access or store anything.

Do You Use Third-Party Services?

No.

Cortex doesn't connect to:
- External APIs
- Ad networks
- Analytics platforms
- Cloud storage
- Literally anything outside your browser

What About Updates?

Updates are distributed through:
- Chrome Web Store
- Firefox Add-ons
- GitHub Releases

These platforms may collect download statistics, but we don't have access to that data.

Open Source = Transparent

Cortex is open source. You can inspect every line of code:
👉 github.com/onemli/cortex

If we were secretly collecting data, you'd see it in the code. (Spoiler: we're not.)

Can I Trust This?

Yes, but don't just take our word for it:

1. Read the source code (it's public)
2. Check browser DevTools (no network requests)
3. Review the permissions (minimal and necessary)
4. Ask the community

Data Export & Deletion

Export: Click "Export Data" in settings. You get a JSON file with all your bookmarks.

Deletion: Uninstall Cortex. All data is automatically deleted from your browser's storage.

Changes to This Policy

If we ever change how Cortex works (spoiler: we won't start collecting data), we'll update this policy and the version number in the extension.

Current version: v1.0.0

Summary

| Question | Answer |
|----------|--------|
| Do you collect data? | No |
| Do you track users? | No |
| Do you use analytics? | No |
| Do you share data with third parties? | No (we don't have data to share) |
| Where is my data stored? | On your device only |
| Can you access my bookmarks? | No |
| Do you sell data? | No (again, we don't have data) |

If you don't trust us, read the code. That's why it's open source.



Built this to organize my bookmark graveyard. Hope it helps yours too.
