Privacy Policy

The short version: Focus Filter does not collect, sell, or share any personal data. Everything it knows stays in your browser.

What Focus Filter does

Focus Filter ("the extension") runs on YouTube pages to hide, replace or block videos you have chosen not to see, such as Shorts, Mix playlists and videos that don't match your study settings.

Information we collect

None. We do not operate any servers for the extension, and it makes no network requests to us or to any third party. We do not use analytics, advertising, cookies or tracking of any kind.

Information processed on your device

• Page content: to decide whether a video is a distraction, the extension reads video titles, channel names and durations that are already shown on the YouTube page. This happens locally and this information is never stored or transmitted.
• Your settings and lists: your preferences, blocked and allowed channels, blocked keywords, hidden videos, time limit settings and Focus Guard pairings are saved with chrome.storage. Small settings are stored in storage.sync, which Chrome may sync across your signed-in browsers through your Google account under Google's own privacy policy. Larger lists and statistics are stored in storage.local and never leave your device.
• Usage counters: simple on-device counts such as "videos hidden today" and the minutes of off-topic video watched today for the time limit. They are never sent anywhere.
• Your images and audio: the extension ships with built-in memes and sounds. Any image or audio you add, or record, is stored in storage.local on your device and played locally.
• Microphone: only if you press Record in settings, for at most 3 seconds. The recording is saved on your device and is never uploaded.

Permissions, and why

• storage - save your settings and lists.
• alarms - end temporary pauses and send time limit reminders at the right time.
• Access to youtube.com - required to filter what YouTube shows you. The extension only runs on YouTube.

Remote code

The extension does not load or run any remote code. All of its code ships inside the extension package.

Data sharing

We do not sell, rent, trade or transfer user data to anyone, for any purpose, because we do not have any.

Children

The extension is suitable for students of any age. Since it collects no personal information, it does not knowingly collect data from children.

Your control

You can change or clear every setting and list in the extension's options page, or remove everything at any time by uninstalling the extension.

Changes to this policy

If this policy changes, we will update the date at the top of this page. Material changes will also be noted in the extension's release notes.
