PrettyCanvas Privacy Policy

Last updated: August 13, 2026

PrettyCanvas is a browser extension that improves the appearance and functionality of Canvas LMS. This policy explains what information the extension accesses, how it is used, and where it is stored.

Information PrettyCanvas Handles

To provide its features, PrettyCanvas may access information available through the user’s existing Canvas LMS session, including:

• Name, email address, profile information, and Canvas user ID

• Courses, enrollments, assignments, grades, submissions, and due dates

• Announcements, discussions, inbox messages, and submission comments

• Calendar events, files, modules, pages, and other Canvas course content

• User preferences, custom themes, course colors, layout settings, and approved Canvas domains

PrettyCanvas uses this information only to display and operate its redesigned Canvas interface. It does not access or store the user’s Canvas password.

Local Storage

Preferences and temporarily cached Canvas information are stored locally on the user’s device using browser extension storage. PrettyCanvas does not operate developer-controlled servers and does not transmit this information to the developer.

Locally stored information can be removed by clearing the extension’s storage or uninstalling PrettyCanvas.

Google Calendar Integration

Connecting Google Calendar is optional and requires an explicit action by the user.

When enabled, PrettyCanvas:

• Stores Google OAuth access and refresh tokens locally on the user’s device

• Reads the user’s calendar list and PrettyCanvas-created calendar events

• Sends selected Canvas event information directly to Google Calendar, including course names, assignment titles, due dates, Canvas links, points, and event identifiers

• Creates, updates, or deletes Google Calendar events according to the user’s synchronization settings

This information is transmitted directly between the user’s browser and Google over HTTPS. It is not sent to the PrettyCanvas developer.

Users can disconnect Google Calendar within PrettyCanvas or revoke access through their Google Account permissions. Events already created in Google Calendar may remain until the user deletes them.

Sharing and Selling Information

PrettyCanvas does not:

• Sell user information

• Use user information for advertising

• Use analytics or tracking services

• Build advertising profiles

• Allow the developer or other humans to read user information

• Transfer user information for purposes unrelated to PrettyCanvas features

Information is shared only with the user’s Canvas LMS provider and, when the optional Calendar integration is enabled, Google, as necessary to provide the requested features.

Google API Limited Use

PrettyCanvas’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy and the Chrome Web Store User Data Policy, including the Limited Use requirements.

Data Security

PrettyCanvas uses HTTPS when communicating with Canvas LMS and Google APIs. Authentication tokens and preferences are stored locally through the browser’s extension-storage system.

Changes to This Policy

This policy may be updated when PrettyCanvas features or data practices change. Updates will be published on this page with a revised date.
