Browser toolbar calculator popup for basic arithmetic

Provides quick-access calculator without leaving the current web page; persists calculation state so work is not lost when the popup closes

User clicks the calculator icon in the Chrome toolbar → calculator popup opens with previous state restored → user performs arithmetic via buttons or keyboard → result can be copied to clipboard → closing and reopening the popup restores the last calculation from localStorage.

Target users: General Chrome users needing a quick, persistent calculator / Users doing frequent percentage/discount/tip calculations while browsing

Monetization

No paid features detected

The extension explicitly states 'It's Free!' in its description and meta tags. No features are gated behind payment. The only payment-related code is a voluntary $5 PayPal tip button (calculatorResponsive.js:618) that opens an external donation page — it does not unlock any functionality. No premium, subscription, purchase, or billing code exists. The 'pro' keyword matches are all false positives from Bootstrap library code (stopPropagation, prototype, truncate, reciprocal).

Confidence: 95
Payment platform: paypal
Source: AI / High
Login required: No
Reason: No login UI, no authentication flows, no account creation. The extension is a self-contained calculator popup that uses localStorage to persist state. All 'login-related' keyword matches are false positives from Bootstrap Authors copyright text, Bootstrap Icons sign-intersection glyphs, and the _metadata/verified_contents.json JWT payload (content signing, not authentication).
