# Dark Mode Extension — Night Eye

Night Eye is a **dark mode extension** that changes bright websites into customizable dark themes. It is available for Chrome, Safari, Microsoft Edge, Firefox, Opera, Brave, and other compatible Chromium-based browsers.

Instead of applying a basic full-page color inversion, Night Eye analyzes page colors and interface elements and is designed to preserve photos, videos, and other important media. Webpage conversion is performed locally on the user's device.

This is Night Eye's official public reference and issue tracker. The proprietary source code for the commercial extension is **not** published in this repository.

## What a dark mode extension does

A browser's dark interface does not automatically make every webpage dark. A dark mode extension works at page level: it reads the visual styles a website supplies and applies appearance changes inside the browser.

Night Eye uses this access to convert website colors and interface elements. Users can apply one set of preferences across websites or create settings for individual sites. On supported websites that already have a built-in dark theme, Night Eye can control that theme from the extension.

## How Night Eye converts websites

1. **Reads visual page elements.** Night Eye uses browser-granted access to inspect the colors and styles required for website conversion.
2. **Processes the page locally.** The conversion takes place on the user's device rather than sending webpage content to Promotino for processing.
3. **Applies a dark palette.** Text, backgrounds, controls, small interface images, and icons can be adjusted while significant media is generally preserved.
4. **Remembers preferences.** Per-website settings are stored or synchronized through browser-provided storage and sync features.

Night Eye offers three appearance modes:

- **Dark:** converts supported page colors and visual elements into a dark theme.
- **Filtered:** keeps the website's original colors while allowing adjustments such as brightness, contrast, warmth, and dimming.
- **Normal:** leaves the website in its regular appearance.

See the [Night Eye features page](https://nighteye.app/features/) for current feature details.

## Main features

## Privacy and browser permissions

To apply a dark theme to website content, Night Eye needs permission to read and change that content. Without this permission, Night Eye cannot perform the conversion. It uses the access to analyze and modify website colors and visual elements locally.

According to Part I of the [Night Eye Browser Extension Privacy Policy](https://nighteye.app/privacy-policy/):

- Promotino does not receive visited webpage URLs or domains, page content, or browsing history during webpage conversion.
- The extension does not contain Google Analytics, Microsoft Clarity, advertising trackers, telemetry, or crash-reporting tools.
- Essential authentication and license-verification requests may transmit an internal user ID or authentication token, plan and subscription status, extension and browser version, device or browser information, IP address, and request time.
- Those functional requests do not include webpage URLs, domains, webpage content, or browsing history.

Read the complete [Night Eye Privacy Policy](https://nighteye.app/privacy-policy/) for the precise scope, data categories, purposes, and retention information.

## Compatibility and known limitations

Night Eye works on most websites, but no browser extension can override every browser or website restriction. A page may be only partly converted when browser-protected content or particular website technology prevents an extension from changing it.

If a site does not look right, first refresh the page and confirm that Night Eye is set to **Dark** for that site. If the problem continues, report it with enough information for the team to reproduce it.

## Report a website or extension bug

[Open a public GitHub issue](../../issues/new) for a reproducible website-conversion or extension bug that does not contain private information.

Include:

1. The affected website or page URL
2. What you expected to see and what happened instead
3. Exact steps that reproduce the problem
4. Browser name and version
5. Operating system or device
6. Night Eye version
7. A screenshot or short recording, when useful

Remove names, messages, account details, payment information, authentication codes, and other private data before uploading evidence. A clear report helps the team reproduce and investigate the issue; it does not guarantee that every website-specific problem can be fixed.

## Public issue or private support request?

| Use GitHub Issues for | Use private Night Eye Support for |
| --- | --- |
| Reproducible website-conversion bugs | Account, login, subscription, or billing questions |
| Extension behavior that can be described without private data | Reports containing private or identifying information |
| Browser-specific compatibility problems | Security-sensitive details or suspected vulnerabilities |
| Publicly useful technical follow-up | Individual troubleshooting that is not reproducible publicly |

For private help, use [Night Eye Support](https://nighteye.app/support/) or email [support@nighteye.app](mailto:support@nighteye.app). Do not publish passwords, authentication tokens, payment-card details, or security-sensitive information in a GitHub issue.
