PasteNinja — Privacy Policy

Effective date: 2026-06-13

Summary

PasteNinja does not collect, transmit, store, sell, or share any user data. It runs entirely inside your browser and never communicates with any external server.

What the extension does

PasteNinja is a content script that watches for paste events on input fields. When it detects that a site has rejected a paste, it re-inserts your clipboard text into the field. All processing happens locally inside your browser. The extension does not maintain any user account, does not connect to any backend, and does not interact with any third-party service.

Data collection

None. PasteNinja does not collect:

• Personally identifiable information (name, email, address, etc.)
• Health, financial, or authentication information
• Personal communications
• Location data
• Browsing history
• Website content beyond the in-memory clipboard text of the paste event currently being processed
• Analytics, telemetry, or usage metrics

Data transmission

PasteNinja makes no network requests of any kind.

Data storage

PasteNinja stores nothing — no cookies, no localStorage, no chrome.storage, no IndexedDB. It has no persistent state.

Permissions

PasteNinja requests host access to all sites (<all_urls>) so its detection-and-inject logic can run wherever you might encounter a paste blocker. It does not request the storage, tabs, cookies, identity, or any other privileged permission.

Source code

PasteNinja is open source. The full implementation is available at github.com/dr-skot/paste-ninja under the MIT license. The content script is short enough to read end-to-end in a few minutes.
