# Privacy Policy for CogTab

*Last updated: August 23, 2026*

CogTab ("we", "our", or "the extension") is committed to protecting your privacy. This Privacy Policy explains our practices regarding your data when using the CogTab Chrome Extension.

---

### 1. Local-First & Zero Data Collection
CogTab is built with a strict **local-first architecture**:
- **No Personal Data Collection:** We do not collect, store, transmit, or sell any personal data, usage metrics, or browsing history.
- **No Third-Party Analytics:** We do not embed any third-party tracking scripts, cookies, analytics SDKs, or advertisements.
- **No External Servers:** CogTab does not send your notes, tasks, tags, or settings to any external servers.

---

### 2. Where Your Data is Stored
- **IndexedDB (Local Storage):** All note content, titles, checklists, and column layouts are stored exclusively inside your browser's local IndexedDB instance.
- **Chrome Storage Sync (Optional):** Lightweight note metadata (such as note IDs, tag names, and pin states) is stored in Chrome's encrypted built-in sync storage (`chrome.storage.sync`) solely to allow sync between your own logged-in Chrome devices.

---

### 3. Permissions Used and Why
- `storage`: Required to save your notes, settings, and UI preferences locally.
- `contextMenus`: Enables the right-click "Save to CogTab" web-clipping feature.
- `notifications`: Sends optional desktop alerts for overdue due dates or clipping confirmations.
- `alarms`: Used to trigger periodic background tasks (such as 30-day trash auto-cleanup).
- `activeTab` & `scripting`: Used only when you choose to clip selected text from a webpage via the context menu.

### 4. Changes to this Policy
If we update this Privacy Policy in the future, changes will be posted directly to this repository and in the Chrome Web Store extension listing.
