Privacy Policy — CoralClock: Screen Time & Website Blocker

Effective date: 2026-07-08

What data CoralClock collects

CoralClock collects the following information about your browsing activity, solely to provide its screen-time tracking and website-blocking features:

No personal account information, credentials, or payment data is ever collected.

How your data is stored

All data is stored locally on your device only, using the browser's built-in storage APIs (chrome.storage.local and IndexedDB). It is never transmitted to any external server, cloud service, or third party.

Data sharing

CoralClock does not share, sell, rent, or transmit your data to anyone. There are no analytics services, advertising networks, or third-party SDKs included in the extension.

Permissions used

PermissionReason
storageSave browsing intervals, rules, and settings locally
tabsDetect which tab is active to measure time accurately
webNavigationDetect page navigations to start and stop time tracking
declarativeNetRequestWithHostAccessBlock sites when a time limit is reached

<all_urls> (optional host permission)Requested only for the specific site(s) you set a rule on, so CoralClock can redirect that site once its limit is reached; a rule for a keyword or regex pattern requests it for all sites since no single site can be named in advance. Not held for sites you haven't set a rule for.

Your control over your data

You can view, prune, and permanently delete your browsing data at any time using the Manage Storage page within CoralClock. Uninstalling the extension removes all data.

Data export

CoralClock allows you to export your data as a JSON file for backup or personal analysis. This file stays on your device and is never uploaded anywhere by the extension.

If this policy changes materially, the updated version will be published at this URL with a new effective date.
