Docs Dark Privacy Policy
Effective 2 November 2026 · Applies to the Docs Dark browser extension for Google Docs™
In short: Docs Dark never reads, stores or sends the content of your documents. It has no ads, no analytics and no tracking.
The only personal information involved is your email address, and only if you buy a licence or log in to restore one. Payments are handled by ExtensionPay and Stripe, never by the extension.
Who we are
Docs Dark is made by Omar Al Qweider, trading as OltreLabs, based in London, United Kingdom ("we", "us"). We are the data controller for the limited information described below.

What the extension does
Docs Dark changes how Google Docs pages look in your browser. It darkens the document page and lightens the text while keeping highlights, text colours and images intact. All of this happens on your own computer, inside your browser.
Information we do not collect
• The text, images or any other content of your documents
• Your browsing history, or which documents you open
• Your Google account details
• Analytics, usage statistics, crash reports or advertising identifiers
• Card or bank details (these go directly to Stripe on its own secure page)
Information that is used
• Your dark mode on/off setting
Why: To remember your choice
Where it is kept: Only on your computer, in the browser's extension storage
• Licence status (free trial or unlocked) and the date you installed
Why: To run the 7-day free trial and unlock the extension after purchase, including offline
Where it is kept: On your computer, and with ExtensionPay, linked to a random ID for your installation
• Your email address (only if you buy or log in)
Why: To link your purchase to your licence, send your receipt, and let you restore your licence on another computer
Where it is kept: With ExtensionPay and Stripe
• Payment details (only if you buy)
Why: To process your one-time payment
Where it is kept: With Stripe only. We never see your full card details.
Our legal basis for using your email and licence status is that it is needed to provide the licence you bought (performance of a contract).
Service providers
• ExtensionPay (extensionpay.com) manages trials, licences and logins. The extension contacts ExtensionPay's servers to check whether a licence has been paid for.
• Stripe (stripe.com/privacy) processes payments.
These providers handle your information under their own privacy policies and may process it outside the UK. We do not sell, rent or share your information with anyone else. We do not use it for advertising, profiling or decisions about creditworthiness.
Permissions the extension asks for
• Access to docs.google.com: to change how Google Docs pages are displayed. The extension runs only on Google Docs documents.
• Storage: to save your on/off setting and licence status on your computer.
How long we keep information
Settings on your computer are deleted when you uninstall the extension. Purchase records (your email and payment record) are kept by ExtensionPay and Stripe for as long as your licence is valid, and for as long as the law requires for tax and accounting records.
Your rights
Under UK and EU data protection law you can ask to access, correct or delete your information, object to its use, or receive a copy of it. Email us at the address above and we will reply within one month. You can also complain to the UK Information Commissioner's Office (ico.org.uk) or your local data protection authority.
Children
Docs Dark is not directed at children under 13, and we do not knowingly collect information from them.
Changes to this policy
If we change this policy, we will update this page and the effective date above. Significant changes will also be noted in the extension's store listing.
