This app can steal your personal info such as addresses, phone numbers, passwords, credit card info, etc. it can also turn on your computer/device without you even on it. It can remotely control your device and remotely log you in. Aka, a remote access tool, in other words... Malware

Classroom management web helper extension that extends LanSchool Student software capabilities in Chrome, enabling teacher-side monitoring and control of student browsing activity

Helps teachers maintain an effective learning environment by monitoring student web browsing, enforcing website filtering policies, blanking student screens during class, capturing screenshots for oversight, detecting banned words in student keystrokes, and managing browser tabs remotely

Extension runs passively on student devices. It connects to locally installed LanSchool Student software either via localhost HTTP requests (Windows) or Chrome extension messaging (Chromebook). The teacher controls student browsing through the LanSchool Teacher console. The web helper monitors URL changes, reports browsing history, enforces web filtering (blocking/allowing URLs per teacher policy), captures tab screenshots, blanks student screens on command, and detects banned words typed by students. If LanSchool Student software is not running, the extension becomes dormant and inactive.

Target users: Students in LanSchool-managed classrooms (extension installed on student Chromebooks/browsers)

The extension is a companion to proprietary LanSchool Student software, so full end-to-end functionality cannot be tested without that infrastructure
The ChromeAppsWhitelist (referenced at line 1600) contents are not visible in the source but determine which external extensions can communicate with this one
LanSchool the commercial product may have paid licensing for schools, but that is external to the extension itself

Monetization

No paid features detected

No payment, subscription, billing, license, upgrade, premium, or feature-gating mechanisms exist anywhere in the extension source code. A grep for subscribe|premium|trial|license|upgrade|checkout|payment|stripe across all 32 text files returned zero matches. All keyword hits for 'pro' are false positives from locale strings ('product_name'), JavaScript built-ins (Promise, Promise.reject), property/prototype references, and copyright notices. The extension itself is a free companion helper for LanSchool classroom management software; while LanSchool as a product is commercially sold to schools, the extension contains no internal paid features.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login UI or authentication flow. The 'studentLoginName' (background.js line 690) is extracted automatically from system context passed by LanSchool Student software—it is not a user authentication prompt. The extension operates passively: it monitors browsing, communicates with local LanSchool Student software via localhost HTTP and Chrome extension messaging, and becomes dormant when no LanSchool Student software is connected. No login credentials, OAuth, or account creation is required from the student user.
