Firefox Relay Privacy Notice by Mozilla
This document is the Privacy Notice for Firefox Relay, a service that provides alias email addresses to protect your primary email. It details what information Mozilla collects, processes, and shares when you use Firefox Relay, including account information, email messages, alias usage, and technical data. It also outlines how user data is shared with third-party service providers like AWS for service delivery.
Firefox Relay Privacy Notice
Version 1.3, Effective March 10, 2022
Firefox Relay allows you to keep your primary email address safe and private from online services by making unique, random (alias) email addresses. This privacy notice explains what data Firefox Relay, shares, and why. We also adhere to the Mozilla Privacy Policy for how we receive, handle, and share information.
Information We Collect
Firefox Account information: This service requires a Firefox Account, which sends Mozilla your email address, locale, and IP address. Mozilla maintains a copy of your account information to provide the service, in particular to associate your primary email address with your alias email address(es).
Email messages: To send and forward your email messages from your alias email address(es) to your primary email address, Firefox Relay processes your email messages. We do not read or store the content of any of your messages. In the event that an email cannot be delivered to you, we will keep it on our servers and delete it after it has been delivered (in no event will we hold onto it for more than three days). If you use the feature to block promotional emails, the Service will check email headers to determine whether the email should be blocked.
Aliases and where you use them: If you create a custom alias, Mozilla stores it in order to forward emails to it. Mozilla stores the site where you created the alias, sites where you subsequently use the alias, and any labels associated with the alias in order to ensure that your aliases are easily findable when you’re ready to use them. Learn how to enable and disable these features here.
Interaction data: Mozilla receives data from interactions with Firefox Relay, such as when you click on “sign up” or “add to Firefox” buttons, and when you create, disable, or delete an alias email address.
Technical data: Mozilla receives basic information from Firefox Relay about your device and browser, including browser version, language, device operating system, and hardware configuration.
Payment information: If you subscribe to Firefox Relay Premium, you will send payment through one of our third-party payment providers: Stripe or PayPal. Mozilla receives a record of your account (including your billing address and the last four digits of your payment method) and the status of your account’s subscription. Mozilla does not store your full payment details.
Read the telemetry documentation for Firefox Relay. You can opt-out of telemetry collection by turning on the Do Not Track (DNT) feature in your browser.
Information We Share
Firefox Relay shares information with a third party to provide the service to you. Mozilla has contracted with this company requiring them to protect your information. Here’s who we use to support Firefox Relay:
Amazon Web Services: Amazon Web Services (AWS) is a cloud-computing platform. Firefox Relay uses AWS to receive emails sent to your alias email address(es) and to forward them to the primary email address associated with your Firefox account. Only Mozilla knows the association between your primary email address and your alias email address(es).

Templates in our curated library are professionally drafted for US or UK law. The wider library comes from the GitLaw community and public sources - a solid starting point, but check any template fits your situation before you rely on it.
Mostly US and UK law. Some templates use general commercial terms that work across jurisdictions, and many note which law they're written for.
It depends on the situation. Templates work well for routine business agreements. For anything involving significant money, complex IP, employment, or areas you're unsure about, it's worth getting professional advice before you sign. GitLaw provides templates and tools, not legal advice.
Open any template in GitLaw and describe the change you want in the chat — 'make clause 4 mutual' or 'add a 30-day notice period', for example. GitLaw drafts the revised language and shows it as a suggested edit. You accept, reject, or keep editing from there.
Yes. Upload a Word, PDF, or Markdown file and GitLaw will open it in the editor. You can review, edit, or chat with GitLaw about it the same way you would with any template from the library.
