Is rePub safe?

Clean risk

rePub converts the active tab into an EPUB and uploads it to reMarkable cloud when cloud upload is selected.

When you click the extension, rePub captures the current tab as an MHTML snapshot and renders it into an EPUB. If the extension is configured to send documents to reMarkable instead of downloading locally, it uploads that generated EPUB using your reMarkable device token.

Shared hosts - 3 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed rePub contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
