What we get
Only what you choose to send us. No account, no ads, no tracking.
This website is separate. It gets your email only if you join the list or give it when you write to us.
Why Chrome shows a warning when you install
Chrome words that warning very broadly, the same way for any extension that works with web pages and tabs. Focusium needs that reach so its pause page can replace a site you didn’t choose, and so it can hide feeds on a few social sites. You can also search your own history to pick your sites.
Keep a backup
Backup puts your settings, sites and stats in one protected file.
