Is Calendar View Tab safe?

Medium risk

Calendar View Tab sends new-tab search terms to Yahoo with fixed tracking parameters.

When you submit a search from Calendar View Tab's new tab page, the extension reads the typed query and opens a Yahoo search URL containing that query. The URL also includes fixed tracking parameters such as vmimp=calendar, uid=dBm2wI1paWdgccyLvYX9RwrU, and type=6171. This behavior is limited to searches submitted through the extension's own new tab page.

Same store account

2 other listings published from this account, 17k+ users between them. 2 of them carry a finding.

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 Calendar View Tab 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.
