LoopSlice collects nothing, sends nothing, and has no servers. Everything happens locally in your browser.
What data the extension handles
- Nothing is transmitted. No backend, no analytics, no third-party trackers. Your browsing, the videos you watch, and your exports are never sent anywhere.
- Settings (panic-key URL, UI preferences) are stored locally via Chrome’s storage API. If Chrome Sync is on, Chrome — not this extension — may sync these small settings across your own devices.
- Exported clips are written only to the folder you choose (Downloads by default), via Chrome’s downloads API or a folder you explicitly grant.
Optional Private Mode
Private Mode is off by default and entirely optional. When enabled, exports are encrypted on your device (WebCrypto: RSA-OAEP + AES-256-GCM) with a key derived from a passphrase you choose. The passphrase never leaves your machine. There is no passphrase recovery — if you forget it, those clips cannot be decrypted by anyone, including us. This is a deliberate security property.
Permissions
- Host access — only to place the loop/speed/zoom overlay on video elements on pages you visit. It does not read page text or send page contents anywhere.
- storage — save your settings locally.
- downloads — save exported clips to your Downloads folder.
