Suspicious in code review (v1.5.3)
Our reviewer found behaviour consistent with malware in version 1.5.3, but not enough to confirm it. Treat this extension as untrusted until it has been re-reviewed.
What our analysis found
Scientific Calculator, used by 100,000 people, is rated caution by Extension Auditor. Our code review reported 2 findings (1 high, 1 low), led by other. It comes from a trusted publisher and was last updated in October 2026.
Key findings
- High
Other
The bundled manifest is Manifest V2 with no permissions, but the live Chrome Web Store listing shows Manifest V3 with 'contextMenus' and 'system.display' permissions. This mismatch could indicate a version discrepancy or a potentially malicious update not reflected in the provided source.
- Low
Tracking
The options page loads Google Analytics (UA-106564552-1) without disclosing any data collection in the Chrome Web Store privacy disclosures. This sends pageview data to a third-party analytics service, which is inconsistent with the 'none declared' data collection claim.
Analyst notes
The source code of the calculator is itself clean with no obvious malicious behavior, but two issues stand out: (1) a manifest mismatch between the bundled version (Manifest V2, no permissions) and the live Chrome Web Store listing (Manifest V3, contextMenus + system.display), which may indicate an un-reviewed update; (2) undisclosed Google Analytics tracking on the options page, which contradicts the CWS 'none declared' data-collection claim. These warrant suspicion.
