Permissions and privacy
Page access
Blocking and tab-management features may need browsing-history, tab, notification, or site access. Match the install prompt to the features you plan to use.
Data notes
Focus tools can learn which sites and tabs you use. Confirm whether those signals stay local, sync to an account, or support analytics before enabling broad access.
Pricing
Free core features with optional paid upgrades. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
