Is GuinRank-Write safe?

Low risk

GuinRank-Write stores its extension URL in each site's localStorage when its content script runs.

GuinRank-Write runs a content script across all websites and writes a GuinExtentionId value into the page's own localStorage. That value contains the chrome-extension:// URL for this extension, so scripts from the same site origin can read that stored extension identifier after navigation.

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