Privacy policy

Effective 18 May 2026

Kosher Browser is a local Chrome extension that helps users block distracting or inappropriate websites with schedules, a focus timer, password protection, strict mode, and SafeSearch enforcement. This page explains, in plain English, exactly what data the extension touches.

What we collect

Nothing. Kosher Browser collects no personal data, no analytics, no telemetry, and no crash reports. There is no account system because there is nothing to associate to an account.

Where your settings live

All settings are stored locally in the browser's IndexedDB and chrome.storage — on your own machine. The bytes never leave your computer.

What is stored

• Your blocklist, allowlist, category preferences, and schedule.
• Whether the focus timer is active and when it ends.
• A cryptographic hash (SHA-256) of your password, if you set one. The plaintext password is never stored anywhere.
• Counts of how many sites have been blocked (for the in-extension statistics view).
• Your interface language preference (Hebrew or English).
• Whether SafeSearch enforcement is on.

Network requests

Kosher Browser makes zero outgoing network requests. You can verify this yourself: open Chrome DevTools on the extension popup or options page, go to the Network tab, and use the extension. The list stays empty. No third-party SDKs, no fonts loaded from a CDN, no analytics beacons.

Permissions explained

• storage — stores your settings via chrome.storage.local.
• alarms — runs hourly checks of the schedule (is the current time inside a block window?) and end-of-focus-session timing.
• declarativeNetRequest — performs URL-level blocking. The rule list is built only from your local settings.
• declarativeNetRequestWithHostAccess — required to scope SafeSearch redirects to Google/Bing/etc. host names.
• host: <all_urls> — required to block or allow any URL the user chooses. The extension does not read page content — DNR operates at the URL level only.

Third parties

None. No third-party services are contacted, no third-party libraries phone home, no fonts are fetched from Google or anywhere else.

Google Limited Use Policy compliance

Kosher Browser complies with the Google API Services User Data Policy, including the Limited Use requirements. Any user data the extension touches is used solely to provide the user-facing feature (blocking sites, focus timer, etc.) and is never transferred to third parties, used for advertising, used to improve unrelated products, or read by any human at our end — because there is no server-side component.

Cookies

None.

Children

Kosher Browser is not directed at children under 13. We don't collect any data from anyone, including children.

Changes

If we ever add an optional cloud-sync feature, it will be strictly opt-in and accompanied by an updated version of this policy that explains what is uploaded and where. The default forever is local.
