Is Block Websites on Chrome - Website Blocker & Focus Timer safe?

Low risk

Block Websites Focus Timer sends usage metrics and a persistent device ID to Amplitude's EU analytics servers.

Each time the extension starts or is updated, it transmits a device identifier along with behavioral properties — including whether a password is set, how many sites are blocked, focus sessions completed, and total focus minutes — to api.eu.amplitude.com. Individual user actions are also tracked and sent with browser platform and language data. Data collection is sampled at 3% of events.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
