This policy applies to the 'Selena' extension for Chromium-based browsers. It is intended to remain consistent with the selections and descriptions in the 'Privacy Practices' section of the Chrome Web Store Developer Dashboard. In the event of any conflict, the actual behavior of the extension and the disclosures provided on this page and in the dashboard shall prevail.
1. Single Purpose
Selena is a Manifest V3 extension designed for a single purpose: to provide a forced dark mode appearance on any website.
It prioritizing user legibility through intelligent style injection and granular site-specific overrides.
2. Data Collection and Usage
We value your privacy. The extension follows these core principles:
No Remote Transmission: Your browsing history, site data, and extension settings never leave your local browser environment. We do not operate any backend servers for collecting user information.
Local Storage: Preferences such as theme modes, filter values, and origin-specific override rules are stored locally using the chrome.storage.local API.
On-Device Processing: All color math and style calculations (powered by WebAssembly) run directly in your browser. No page content is sent to third-party APIs for analysis.
Chrome Web Store Compliance: Under the Google User Data Policy, processing page content (e.g., background color sampling) constitutes handling of sensitive information. This document and our dashboard disclosures ensure transparent handling of that data for the sole purpose of rendering the dark mode.
Data is used only to provide the product's user-facing features (Dark Mode).
Absolutely no data is sold to third parties.
No data is used for personalized advertising or creditworthiness analysis.
No human interaction with your browsing data is permitted under any circumstances.
4. Permissions
storage: Used to persist your theme preferences locally.
content_scripts: Required to inject CSS and analyze page colors for styling.
all_urls: Necessary to enable dark mode functionally across the diverse range of websites you visit.
5. Security and Remote Code
In compliance with Manifest V3 requirements, Selena prohibits any execution of remotely hosted code.
All logic, including CSS engines and WASM binaries, is bundled locally within the extension package.
6. Changes to This Policy
We may update this policy occasionally. Significant changes will be reflected in the "Effective Date" at the top of this page.
Continued use of the extension after updates constitutes agreement with the revised policy.
