Overview

Klokd is built privacy-first. All data stays on your device — we have no servers, no accounts, and we collect nothing about you.

Data We Collect

Klokd collects no personal data. The extension only stores the following locally in your browser:

• Time spent on websites (stored locally in browser storage)
• Your configured time limits and preferences

This data never leaves your device and is never transmitted to us or any third party.

Permissions

Klokd requests the following browser permissions:

• tabs — to detect which site is active and measure time
• storage — to save your usage data and settings locally
• alarms — to trigger limit notifications

No permission is used to read page content, form data, passwords, or any personal information.

Third Parties

Klokd does not share any data with third parties. There are no analytics, no tracking pixels, no ads, and no external API calls made by the extension.

Data Deletion

All data is stored in your browser's local storage. You can delete it at any time by uninstalling the extension or clearing the extension's storage via your browser settings.

Contact

If you have any questions about this privacy policy, please open an issue on our GitHub or contact us via the Firefox Add-ons listing page.

Common Questions

• Does it work in private/incognito mode? — Only if you explicitly allow it in your browser's extension settings.
• How do I reset all my data? (Firefox) — Go to the Add-ons Manager, find Klokd, and clear its storage under Permissions.
• How do I reset all my data? (Chrome) — Go to chrome://extensions, find Klokd, click Details, then clear site data.
