Is Sticky Notes safe?
Sticky Notes embeds an OAuth client secret and sends it to its token endpoint during login.
The extension's production bundle includes a hardcoded OAuth client secret alongside its client ID. When a user logs in through the popup, the background script sends that secret in a POST request to the Sticky Notes token endpoint.

Shared hosts - 1 hostname
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 Sticky Notes 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.
