CAUTION
Mostly fine, but a few things worth reviewing before you install.

Automated analysis of publicly available code — not a professional security audit. It may produce false positives and does not prove an extension is unsafe or safe. Treat it as one signal among many. Disclaimer · Report an issue

Recorded findings: 1 critical and 1 high severity. Read the finding details before interpreting the score; automated flags are not proof of malicious behaviour.

Automated analysis looks for suspicious code, permissions and other risk signals. It does not observe every runtime behaviour or independently audit the publisher’s servers. A low-risk result is not a guarantee of safety. How our checks work.
