Is DeepDyve Plugin safe?

Low risk

DeepDyve Plugin sends saved research search URLs and article-view metadata to DeepDyve by default.

On supported research pages such as PubMed and Google Scholar, the extension defaults its auto-save settings on and posts saved search details to DeepDyve. Those posts can include a base64-encoded search URL, search title, page type, and article metadata such as DOI, PMID, title, authors, journal, and document URL.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

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 DeepDyve Plugin 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.
