Integrates Acall visitor management into Google Calendar by adding a sidebar panel for registering visitor information and sending appointment emails directly from calendar events

Enables office/visitor management teams to register visitor information (name, email) and manage appointments from within Google Calendar without switching to a separate Acall web application

User opens a Google Calendar event → Acall button appears in the sidebar → User clicks the button → Side panel opens with the Acall app (from admin.acall.jp) embedded as an iframe → The extension sends calendar event data to the iframe → User registers visitor info (name, email) and sends appointment emails via the Acall panel → Appointment details are written back to the calendar event description

Target users: Office administrators managing visitor reception / Companies using Acall visitor management system / Teams that schedule visitor appointments via Google Calendar

The extension is a thin launcher/content script; all core Acall functionality (visitor registration, authentication, billing) is handled server-side at admin.acall.jp and not visible in the extension source
Cannot determine exact login providers without inspecting the admin.acall.jp web app
Cannot determine if the Acall service has paid tiers from extension code alone

Monetization

No paid features detected

No payment, billing, subscription, or upgrade code exists anywhere in the extension source. The keyword matches for 'paid' were false positives (stopPropagation and verified_contents.json metadata). The extension itself does not gate any features behind a paywall or call any payment APIs. Any paid plans for Acall as a service are external to this extension and not gated by extension code.

Confidence: 85
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension embeds an iframe to admin.acall.jp (Acalls service). The code comment on line 587 explicitly states the ACALL_READY message is sent after login ('ログイン後など' = 'after login, etc.'). The manifest also includes sso-redirect.js as a web-accessible resource, indicating an SSO authentication flow on the destination service. The core workflow (visitor registration via the Acall panel) requires the user to be authenticated with the Acall service.
