peek for Gmail does not collect, transmit, or store any personal data. It has nothing to store.

What it does: when your browser navigates to a Gmail attachment link, the browser itself changes one query parameter in that address (disp=safe to disp=inline) so the attachment opens in the browser's viewer instead of downloading. The change is made by a static browser rule. peek contains no scripts, so it never reads your mail, page content, or addresses.

Network requests: peek makes zero network requests of its own.

Analytics and tracking: none. peek contains no analytics, telemetry or third-party code.

Permissions: declarativeNetRequest, to apply the one static rewrite rule; https://mail.google.com/*, so the rule applies only to Gmail attachment links.
