Short description

Turn structured QLearn and Canvas lessons into clear classroom presentations with presenter and audience views.

Detailed description

Hudra turns structured QLearn and Canvas lesson pages into clear, classroom-ready presentations.

Open a supported lesson and launch Hudra from the browser toolbar or with Alt+P. Hudra converts the existing page into a slide-style teaching experience without requiring the lesson to be rebuilt in separate presentation software.

Features include: • Dedicated presenter and audience views • Current and next slide previews • Keyboard and on-screen navigation • Classroom clock and timer • Dual-screen presentation support • Audience zoom and scrolling controls • Support for structured lesson content and embedded media • Quick restoration of the original lesson page when presenting ends

Hudra processes lesson content and generated slide previews temporarily in browser memory to provide the requested presentation. Lesson content and previews are not written to extension storage or transmitted to Napper.au.

Hudra stores only temporary presentation-session metadata, such as presentation mode and tab and window identifiers, in session-scoped browser storage. This information coordinates and restores an active presentation and is cleared when the browser session ends.

Hudra requires no account and contains no advertising, analytics, telemetry, tracking or remote executable code.

Hudra is an independent project and is not affiliated with or endorsed by Instructure or the Queensland Department of Education.

Single purpose

Hudra converts the active supported QLearn or Canvas lesson page into a temporary, reversible classroom presentation with presenter and audience controls.

Permission justifications

activeTab

Provides temporary, user-invoked access after the toolbar click or keyboard shortcut. Hudra uses it to inspect the selected page and either start presentation mode or display an unsupported-page notice.

scripting

Injects only packaged page-detection and presentation code into the user-selected supported page. No remote code is downloaded or executed.

storage

Stores temporary active-presentation metadata in chrome.storage.session so presenter and audience windows can remain coordinated and the session can recover if the extension service worker restarts. Lesson content is not persisted.

system.display

Detects available displays so Hudra can place presenter and audience windows correctly for dual-screen classroom presentation.

Host permissions

https://*.qlearn.eq.edu.au/* and https://*.instructure.com/* provide access only on supported QLearn and Canvas lesson hosts. This access is particularly required for the newly created dual-screen audience tab because the original tab's activeTab grant does not transfer to that new tab. Hudra still activates only after an explicit toolbar click or keyboard shortcut and does not activate on unrelated websites.

Privacy practices answers

• Handles website content: Yes — lesson content and generated previews are processed temporarily in browser memory to create the requested presentation.
• Handles web browsing activity: select only if the dashboard defines access to the active lesson URL/page as browsing activity. Hudra does not collect or transmit browsing history.
• Personally identifiable information: No, unless future functionality deliberately reads or retains such information.
• Authentication information: No — Hudra does not read or transmit credentials or authentication cookies.
• Financial, health, personal communications, location or form data: No.
• Data sold to third parties: No.
• Data used for advertising or creditworthiness: No.
• Data transmitted off the device by Hudra: No. Existing lesson and embedded resources continue to load from their original providers.
• Limited Use certification: certify after confirming these answers match the dashboard wording.

Privacy policy URL required: publish docs/PRIVACY.md at a stable public HTTPS URL, then enter that URL in the dashboard.

Distribution recommendation

For the first beta, use Unlisted visibility if testing with a controlled teacher group. Use Public only when the support and privacy-policy URLs are live and representative QLearn manual testing is complete.

Reviewer notes

Hudra works only on supported QLearn and Canvas lesson pages. To test it, open a structured lesson page under one of the declared host patterns, click the Hudra toolbar icon, and use the on-screen controls or keyboard navigation. Dual-screen Presenter View requires a second display; single-screen mode can be tested with one display.

Hudra does not modify or save the source lesson. Exiting presentation mode restores the normal page.

If the reviewer cannot access a QLearn environment, provide a test Canvas/Instructure lesson URL and test account through the dashboard's secure reviewer-instructions field. Do not place credentials in this document or in the extension package.

Manual checks before submission

• Test activation and exit on representative QLearn and Canvas lesson pages.
• Confirm unsupported pages show a clear message and remain unchanged.
• Test previous, next, first and last navigation.
• Test Escape and the toolbar button restore the original page.
• Test dual-screen window placement with an attached second display.
• Test audience zoom, scroll, hide and video controls.
• Confirm the privacy-policy and support URLs are publicly accessible.
• Confirm the screenshots contain no private production lesson or student information.
