Is Altmetric for Pubmed and Google Scholar safe?

Low risk

Altmetric for Pubmed and Google Scholar sends page .docsum-pmid text to api.altmetric.com as PubMed IDs.

The extension's content script runs on every site and, outside Google Scholar pages, looks for elements with the .docsum-pmid class. It reads the text from those elements and places it in PubMed lookup requests to Altmetric, so matching DOM text can be sent from pages beyond PubMed itself.

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