Accessibility & Privacy Compliance Statement

Section 1

Executive Summary

This document records the accessibility and privacy compliance status of Grade 3 Math Practice, a progressive web application (PWA) designed for Tennessee TCAP 3rd-grade mathematics preparation. The application was assessed against WCAG 2.1 Level AA using both automated and manual methods. It was additionally reviewed for compliance with FERPA and COPPA privacy requirements.

Section 2

Privacy & Data Protection

Architecture

Grade 3 Math Practice is a fully client-side application. It has no backend server, no database, no user accounts, and no network requests that carry student data. All persistent state (student name/avatar, session scores, streaks, weekly topic selection) is stored exclusively in the browser's localStorage on the device where the app is used.

FERPA Compliance

The Family Educational Rights and Privacy Act (FERPA) protects education records that identify individual students. Grade 3 Math Practice does not create education records as defined by FERPA:

• No student name, ID number, date of birth, or government identifier is collected or required.
• The optional display name entered by the student (e.g., a first name or nickname) is stored only in the device's local browser storage and is never transmitted to any server.
• No session data, scores, or usage logs are sent to or retained by The Compass Institute or any third party.
• No teacher, school, or district identifiers are collected.

Because no personally identifiable information is created or maintained in any institutional system, FERPA's consent and access requirements are not triggered.

COPPA Compliance

The Children's Online Privacy Protection Act (COPPA) applies to operators of websites and online services directed at children under 13 that collect personal information. Grade 3 Math Practice does not collect personal information from children:

• No name, address, phone number, email address, or persistent identifier is collected from children.
• No cookies, tracking pixels, or fingerprinting techniques are used.
• No third-party advertising, analytics, or social media integrations are present.
• No account creation or parental consent flow is required because no personal data is solicited.

COPPA compliance is achieved structurally: the app is designed so that no personal information from children is technically possible to collect or transmit.

Third-Party Services

The application loads no external scripts, fonts, stylesheets, or APIs. All assets are bundled and served from the same origin.

Section 3

WCAG 2.1 Level AA Conformance

Scope: This conformance claim covers the full interactive surface of the application: the welcome/profile screen, profile creation, home screen, weekly topic picker, active practice session (multiple choice and numeric entry question types), and the session results screen.

Key Accessibility Features

Section 4

Automated Testing Results

Automated accessibility testing was performed using axe-core 4.9.1 via the axe DevTools browser extension in Google Chrome. The rule set covered WCAG 2.1 Level A and Level AA (wcag2a, wcag2aa, wcag21a, wcag21aa).

45 rules were inapplicable (audio/video captions, form-specific rules, table structure) and are not counted above.

Math Notation Accessibility

A key accessibility challenge in math education software is ensuring that mathematical notation is correctly spoken by screen readers. The application converts all rendered math symbols to plain spoken English before setting aria-label on question and answer elements:

Manual Testing Evidence

Pending items do not represent known violations. They are planned verification steps that extend the existing automated evidence.

Section 6

Technical Architecture

Application Type

Grade 3 Math Practice is a Progressive Web Application (PWA) built with plain HTML, CSS, and JavaScript. It has no server-side runtime, no API, and no build pipeline. All application code is open to inspection via browser DevTools.

Data Flow

• Input: Student taps or types an answer. The answer is evaluated locally in JavaScript against the correct answer embedded in the question data.
• Storage: Session score, streak count, best score, and weekly topic are stored in localStorage under the key prefix g3mp_. This storage is local to the device and browser.
• Network: After the initial page load, the application makes zero network requests. All content (questions, hints, images) is bundled in the application files.
• Deletion: All stored data can be deleted at any time by clearing the browser's site data (Settings > Privacy > Clear browsing data) or by the student using the profile management screen.

Verification

Any district technology officer can independently verify these claims using Chrome DevTools:

• Network tab: With "Offline" enabled, all features remain functional. With online, filter requests to confirm no data is posted to external servers.
• Application > Local Storage: View the exact keys and values stored. No names, emails, or identifiers will be present.
• Application > Service Worker: View the service worker cache to confirm only application shell files (HTML, CSS, JS, icons) are cached.
• Sources tab: All JavaScript source files are readable. No obfuscation is used.
