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.
