Terms of Service
The rules for using the Dark Reader website, its tools and the Dark Theme for Chrome extension.
Last updated: October 23, 2026Introduction
Welcome
Welcome to Dark Reader. These Terms of Service (“Terms”) govern your use of the Dark Reader website at dark-shiftmode.com (the “Website”), the online tools on it, and the Dark Theme for Chrome extension (the “Extension”). We call them collectively the “Service”. The Service is operated by our team (“we,” “us,” or “our”).
By visiting the Website, installing the Extension or otherwise using our Service, you agree to be bound by these Terms. If you disagree with any part of the terms, you may not access or use our Service.
The Website and Its Tools
Use of the tools
The Website offers free browser tools for reading, writing and working on a dark screen, such as a PDF reader, EPUB reader, text reader, notepad, focus timer, image colour tool, contrast checker, spreadsheet and Word viewers, and a screenshot tool. No account is needed. The tools are meant for personal and everyday use, and you agree to use them in compliance with these Terms and applicable laws.
Your files and content
You keep all rights to the files, text and images you open or create with the tools. We do not claim ownership of them and, as described in our Privacy Policy, the tools process them on your device rather than on our servers.
You are responsible for your content: you confirm that you have the right to open and process the files you use, and that you will not use the tools for anything unlawful or in a way that infringes the rights of others.
My Library and local storage
My Library and some tools save data in your browser’s storage on your device. We do not keep a copy. Clearing site data, switching browsers or devices, using a private window, or a browser or storage limit can remove saved files, notes and settings, and we cannot restore them. You are responsible for keeping your own backups, for example with the Download option in My Library.
Accuracy of results
The tools are provided for convenience. Files can look different from the original after a dark tone or other change is applied, and some formats or features may not display perfectly. The Contrast Checker and Image Color results are guidance only and are not a certification of accessibility or legal compliance. Keep your original files, and do not rely on the Service for critical, legal, medical or financial decisions.
Acceptable use of the Website
In addition to the rules for the Extension below, you agree not to:
- Try to disrupt, overload or gain unauthorized access to the Website or its infrastructure
- Copy, scrape or mirror the Website at scale, or present it as your own or as associated with you
- Use the tools to process content that is illegal or that you have no right to use
Changes and availability
We may add, change or remove tools and features, or suspend the Website, at any time and without notice. We do not promise that any particular tool will always be available.
Third-party services and links
The Website uses services provided by others, including Google Analytics, Cloudflare and Google Fonts, and links to third-party sites such as the Chrome Web Store and Microsoft Edge Add-ons. These are governed by their own terms and policies. See our Privacy Policy for how they are used.
The Extension
Use of Service
Our Extension is designed to provide a dark theme for websites you visit. You agree to use the Service only for its intended purposes and in compliance with these Terms and any applicable laws and regulations.
You agree not to:
- Modify, adapt, or hack the Service or modify another website to falsely imply it is associated with the Service
- Attempt to decipher, decompile, disassemble, or reverse engineer any of the software comprising the Service
- Use the Service in any way that could damage, disable, overburden, or impair the Service
- Use any robot, spider, crawler, scraper, or other automated means to access the Service

Termination

All provisions of the Terms which by their nature should survive termination shall survive termination, including, without limitation, ownership provisions, warranty disclaimers, indemnity, and limitations of liability.
Changes to Terms
We reserve the right, at our sole discretion, to modify or replace these Terms at any time. If a revision is material we will try to provide at least 30 days notice prior to any new terms taking effect.
By continuing to access or use our Service after those revisions become effective, you agree to be bound by the revised terms. If you do not agree to the new terms, please stop using the Service.
Governing Law
These Terms shall be governed and construed in accordance with the laws of the jurisdiction in which our company is registered, without regard to its conflict of law provisions.
