Unlock Copy collects nothing.

WHAT IS NOT COLLECTED

No analytics, no telemetry, no crash reporting, no unique identifier, no usage counts. Nothing you select, copy or visit is recorded, and nothing is sent anywhere. There is no server to send it to.

This is checked rather than promised: the build fails if fetch, XMLHttpRequest, WebSocket, EventSource or sendBeacon appears anywhere in the shipped source. That gate runs on every release build.

WHAT IS STORED, AND WHERE

Two things, in the browser's own extension storage (storage.sync):

1. Your default switches, the ones on the options page.
2. The list of sites you turned "always unlock" on for, plus any per-site switch you changed from its default.

storage.sync is Firefox's own account sync. If you are signed in, Firefox syncs it between your devices the same way it syncs bookmarks. It does not pass through anything belonging to this add-on or its author. If you are not signed in, it stays on that machine. Uninstalling removes all of it.

SITE ACCESS

A fresh install has no access to any website. The manifest requests activeTab, scripting and storage, and no host permissions.

"Unlock this page" uses activeTab, which your click grants for that one tab and which expires when you navigate away. "Always unlock this site" asks Firefox for permission to that one origin; Firefox shows the prompt and you can revoke it at any time, which also turns the site off in the add-on.

Access is never requested for a site you did not ask for.

CLIPBOARD

The add-on does not read your clipboard. When you copy, the browser performs the copy. The add-on's only role is stopping the page from cancelling it, and, if "Clean copy" is on, stopping the page from overwriting what you copied with something else. The copied text is never inspected, stored or transmitted.
