Screen Break Keeper Chrome extension offers full-screen pet-themed break reminders with local-only settings and timer

Screen Break Keeper is a Chrome extension (version 1.0.0, updated May 9, 2026) that displays full-screen break reminders featuring pet themes or user-uploaded photos and videos when a timer ends.

The extension runs one shared browser-wide timer with user-configurable focus and break lengths, applies only to sites on an allowlist or exclusion list, and stores all settings and timer data locally on the device with no account required.

The developer discloses that the extension does not collect or use user data, does not sell data to third parties, and does not use data for purposes unrelated to the extension's core functionality.
