Paper Trail (留痕) is a local-only work-trail extension. We (the developers) cannot see, collect or transmit your note bodies. The extension has no first-party server and no analytics.
1. What we process on your device
- Trail records: title, body, people, tags, time, optional screenshots (stored in
chrome.storage.localonly) - Settings: language, bubble toggle, default types (local only as well)
- Optional Pro unlock via ExtensionPay: a local paid-status cache may be kept for short offline recognition. Payment card data is processed by ExtensionPay / its processors
2. What we do not collect
- Account registration (no sign-in required)
- Cloud sync or backup (unless you export files yourself)
- Analytics / advertising identifiers or crash reporting
- Sending record contents to any AI or third-party API
3. Permissions
| Permission | Why |
|---|---|
storage | Records, settings and local payment cache |
contextMenus | “Save selection” in the right-click menu |
activeTab / tabs | Used when you capture a screenshot or need current-tab context |
| Host permissions | Inject the “＋ Paper Trail” button; inject ExtensionPay checkout on purchase pages. Content scripts do not upload page bodies to any server |
Selection capture and auto-detection run in a local rules engine with no network calls.
4. Network summary
- ExtensionPay (
extensionpay.com) — only when you open purchase or login - No other first-party analytics / ads / cloud-sync requests
