ClipGate Browser Extension Privacy Policy

Last updated: April 2026

ClipGate stores everything locally on your machine. We collect nothing. We send nothing. We track nothing.

Data Collection

ClipGate collects zero data. The extension does not transmit any information to any server, endpoint, or third party. There is no analytics, no telemetry, no tracking, no crash reporting, and no usage metrics.

Data Storage

All clipboard data is stored exclusively in your browser's local IndexedDB database. This data never leaves your machine. It is not synced, backed up, or accessible to anyone but you.

Stored data includes:

The text content you copied
The classified content type (e.g., error, URL, command)
The classification confidence score
The source URL and page title where you copied
A timestamp
A SHA-256 hash for deduplication

Secret Handling

ClipGate automatically detects sensitive content such as API keys, tokens, and passwords. Detected secrets are:

Encrypted with AES-256-GCM before storage
Displayed as [REDACTED] in the popup UI
Auto-expired and permanently deleted after the configured TTL

Permissions

The extension requests the minimum permissions required to function:

activeTab — To inject the content script that captures copy events
storage — For extension settings only (not for clip data)
clipboardRead — To access clipboard content when you explicitly copy
host_permissions (<all_urls>) — To capture copy events on all web pages

Third-Party Services

ClipGate uses zero third-party services. No CDNs, no APIs, no external scripts, no fonts loaded from the web. The extension is entirely self-contained.

Data Deletion

You can delete your clipboard history at any time:

Individual clips — Open a clip and click the delete button
All clips — Click the clear button in the header
Complete removal — Uninstalling the extension removes all data

Children's Privacy

ClipGate does not knowingly collect any data from anyone, including children under 13.
