Privacy Policy

Product: Screen Break Keeper (localized store name in some regions: 全屏守门员)
Last updated: May 7, 2026

This policy describes how the Screen Break Keeper browser extension (the “Extension”, “we”) handles information when you use it. The Extension is a focus timer with immersive full-screen break overlays: it accrues time on sites you configure, then shows a full-screen rest screen (built-in pet-style themes such as panda, cats, and dogs, or media you choose). Data is stored on your device by default. There is no publisher sign-in or cloud account required for normal use.

2. What the Extension does


3. Permissions (as declared in manifest.json)

Permission Purpose
storage, unlimitedStorage Stores your settings (site lists, timer values, theme and backdrop options) and optional user-uploaded break media, which may be large.
alarms Runs timer-related scheduling in the background service worker.
tabs Reads the active tab URL and hostname (and related tab state) to apply your rules, trigger or preview breaks, and similar in-product behavior.
scripting Injects scripts needed for the break overlay in coordination with the Extension’s content scripts.
host_permissions (http://*/*, https://*/*) Lets content scripts run and the overlay appear on pages you open. This is not intended to batch-upload your full browsing history to the developer.

4. Information processed

4.1 Page and tab signals

4.2 Local storage (chrome.storage.local)

May include site rule lists, focus/break parameters, theme and backdrop preferences, and encoded user media. It is stored in local extension storage. Uninstalling the Extension or clearing extension data typically removes it (browser-dependent).

4.3 Network transmission

Core features do not upload your break media or full browsing history to publisher-operated servers. Internally, the Extension may resolve packaged resources using chrome-extension:// URLs; that is not sending your personal content to third-party websites.


5. Third parties

Normal use does not rely on analytics, advertising, or remote databases from third parties as part of core functionality. If optional network features are added in a future version, we will update this policy and the store listing.


6. Security & retention


7. Children

The Extension is not directed at children under 16 to collect personal data.


8. International transfers

Because core data stays on your device, international transfer is minimal for Extension-local storage. If you contact us by email, message handling may occur in various countries where mailbox providers operate.


9. Changes

We may update this policy; the “Last updated” date will change. Material changes may be noted in the Chrome Web Store listing where practical.
