Invisible Window Privacy Policy
Last updated: July 14, 2026
Invisible Window (“the Extension”) is a Chrome browser extension that keeps tabs looking active when you switch away, and optionally blocks Canvas quiz leave-tracking network calls on matching quiz pages.
What we collect
The Extension does not collect personally identifiable information.
The only stored settings are local preference toggles:
- Whether keep-tab-active is enabled
- Whether the Canvas leave-tracking shield is enabled
Those preferences are saved with Chrome’s
chrome.storage.sync API so they can sync across your own Chrome
profile. They are not sent to Invisible Window servers (there are none).
What we do not collect
- Browsing history or URLs (not logged or uploaded)
- Page content, form answers, cookies, or credentials
- Analytics, advertising IDs, or crash telemetry to third parties
How the Extension works on pages
On websites you visit, the Extension injects scripts that adjust how the page reads visibility and focus APIs in your browser. On Canvas quiz URLs, it can block leave-tracking requests to Canvas submission event endpoints. That processing happens on your device. No page data is transmitted to an Invisible Window backend.
Permissions
- storage: save your on/off preferences.
- Host access via content scripts: required so the Extension can run its keep-active behavior on http/https pages you open.
Sharing
We do not sell, rent, or share user data with third parties. We do not use your data for advertising.
Children
The Extension is not directed at children under 13 and does not knowingly collect children’s data.
Changes
If this policy changes, we will update the “Last updated” date on this page.
