Financial Calculator

The extension has a reasonable rating of 3.7 stars from 101 user reviews, indicating moderate user satisfaction. The name "Financial Calculator" clearly describes its purpose, and the developer provides a website domain (financial-calculator.appspot.com) which adds some transparency. However, the lack of detailed developer information and missing data for user count, last update date, and extension size raises some transparency concerns.

The primary concern is the use of Manifest Version 2, which has weaker security protections compared to the newer Manifest V3 standard. This older framework provides fewer safeguards against potentially malicious behavior and data access. The missing technical details (permissions, host permissions, content scripts) make it difficult to fully assess what data the extension can access, though the overall low risk assessment suggests minimal concerning permissions were found.

This extension appears relatively safe for general use given its low overall risk rating and clear financial calculator purpose. However, consider looking for alternative financial calculator extensions that have upgraded to Manifest V3 for better security. If you choose to use this extension, monitor for updates that might migrate it to the newer manifest version. Given the low risk level, running it in a separate Chrome profile is unnecessary unless you handle highly sensitive financial data regularly.
