// TL;DR — THE SHORT VERSION

✓

We collect zero data about you or your browsing.

✓

No analytics, no telemetry, no crash reports sent anywhere.

✓

Your settings live only on your device via Chrome's sync storage.

✓

We have no servers. Nothing you do is ever transmitted to us.

1. Overview

NightShift ("the Extension") is a free, open Chrome browser extension that applies dark mode filters, colour adjustments, and reading enhancements to websites you visit. It is developed and maintained by j@brutal.net.

This policy explains what data the Extension accesses, how it is used, and where it is stored. The short answer is: all processing happens locally on your device and nothing is ever sent to us or any third party.

2. Data We Collect

We collect no data whatsoever.

NightShift does not collect, transmit, store on remote servers, or share any personal information, browsing history, or usage data. There are no analytics, no telemetry, no error reporting, and no usage statistics sent anywhere.

3. Permissions and What They're Used For

The Extension requests the following Chrome permissions. Each one is used solely to provide local functionality:

storage — saves your settings (brightness, presets, whitelist, etc.) locally via chrome.storage.sync. Sync storage replicates your settings across your own Chrome devices if you're signed in to Chrome. No third party ever sees this data.
activeTab — allows the popup to read the current tab's URL so it can show site-specific settings and the whitelist toggle.
scripting — required by Manifest V3 for the service worker to communicate with content scripts on page load.
tabs — used only to broadcast a settings change to open tabs when you toggle dark mode via keyboard shortcut.
alarms — powers the scheduled auto-enable feature. A 1-minute repeating alarm checks the current time against your configured schedule. No data leaves your device.
<all_urls> — the content script needs to run on every page you visit to inject dark mode CSS. The Extension reads no page content and sends nothing to any server.

      Note on <all_urls>: This is a broad permission that allows the content script to run on every website. It is used exclusively to inject a CSS filter onto the page. The Extension never reads, parses, or transmits any page content, form data, passwords, or personal information.
    

4. chrome.storage.sync

Your settings — brightness, contrast, sepia, presets, whitelist, custom CSS, schedule — are stored using Chrome's built-in chrome.storage.sync API.

If you are signed in to Google Chrome, this storage is synced across your own devices by Google. This sync is controlled entirely by Chrome and Google's privacy policy — NightShift has no access to, visibility into, or control over that sync process.

If you are not signed in to Chrome, settings are stored locally only and never leave your device.

5. Third Parties

NightShift does not integrate with, communicate with, or share data with any third-party services, APIs, analytics platforms, or advertising networks.

There are no external network requests made by the Extension at any time.

6. Children's Privacy

NightShift does not collect any data from anyone, including children. The Extension is suitable for all ages.

7. Changes to This Policy

If this policy changes in a meaningful way — for example if a future version adds any form of data collection — the policy will be updated with a new date and the change will be noted clearly. We will never introduce data collection silently.
