Last updated: 25 October 2026. This is a plain-language summary of what the extension can collect and under what conditions.
Tab Glance works fully offline. It never collects anything unless you turn on “Anonymous usage stats”, which is off by default. Even when it is on, the pages you visit — URLs, tab titles and hostnames — are never sent as part of usage stats.
To do its job it reads your open windows and tabs, including titles, URLs and estimated per-tab memory. This stays on your device and is shown only to you in the dashboard.
If you opt in, the extension may send coarse events describing how the tool is used — never what you browse. The complete set of events it can send is fixed in the code and includes only:
dashboard_openedsort_changed (memory / order)filter_usedtab_focused, tab_discarded, tab_closedtab_moved (drag or menu; to an existing or new window)window_freed (with a rough count bucket like “6-10”)memory_methodEach event carries a random installation ID (a UUID generated on your device), the extension version and a timestamp. The ID identifies an installation, not a person, and is not linked to any account, email or browsing data. No event has any field capable of carrying a URL, title or hostname; anything not on the allowlist is discarded before sending.
Separately, you can choose to share a “memory by site” report. This one does include
hostnames (e.g. example.com — 3 tabs — 820 MB), so it is never automatic: the
extension shows you the exact data first, and nothing is sent until you press Send on that
preview. It is transmitted in cleartext so it can be audited.
You can turn usage stats off at any time from the dashboard’s Privacy panel, and reset the installation ID there. Turning it off stops all sending immediately.
If sending is enabled, data goes only to the developer’s own collector endpoint. It is not sold, and not used for anything beyond understanding how the extension is used.
