This Mustang Privacy Notice describes the privacy practices that are specific to the Mustang browser.
Not all of the features discussed in this Privacy Notice appear in all Mustang products. To keep things simple, however, we’re going to use the term "Mustang" on its own to refer to each of the products within the Mustang family. Where an individual Mustang product works in a different way we’ll be sure to highlight that.
For early adopters who want to test features that are still under development, we make available preview versions (also known as beta, dev and canary) of Mustang browser in addition to the stable version. Although this Mustang Privacy Notice applies to the stable and preview versions, it may not be fully up to date when describing features still under development in the preview versions.
You do not need to provide any personally identifying information in order to use Mustang.
When you use any browser, including Mustang, to contact Rafotech's servers, by default Rafotech receives standard log information including your system’s IP address and one or more cookies. You can configure Mustang browser to not accept cookies from or other sites.
Sites that you visit using Mustang will automatically receive standard log information similar to that received by Rafotech’s servers. These sites may also set their own cookies or store site data on your system. You can restrict cookies and other site data in Mustang's preferences page.
If Mustang’s network actions prediction features are enabled, Mustang may look up the IP addresses of all links on webpages and open network connections to load webpages faster. Sites can also use pre-rendering technology to pre-load the links that you might click next.
If you use Mustang in incognito mode or guest mode, it will not transmit any pre-existing cookies to sites that you visit. Sites may deposit new cookies on your system while you are in these modes; these cookies will only be temporarily stored and transmitted to sites while you remain in incognito / guest mode. They will be deleted when you close the browser, close all open incognito windows or exit guest mode.
If you choose to use Mustang’s location feature, this service allows you to share your location with a site. Mustang will not allow a site to access your location without your permission. does not have control over third party websites or their privacy practices. Please carefully consider any website’s privacy practices before consenting to share your location with that website.
Mustang stores some information locally on your system. This may include:
You can always choose to delete your browsing history information, in whole or in part.
You can also limit the information Mustang stores on your system by using incognito mode or guest mode. The Mustang browser offers both modes. Incognito mode is useful if you would still like to have access to information from your existing profile, such as suggestions based on your browsing history, while you are browsing. Guest mode is useful if you would prefer to begin a browsing session without seeing information from any existing profiles. In either of these modes, Mustang will not store basic browsing history information such as URLs, cached page text, or IP addresses of pages linked from the websites you visit. It will also not store snapshots of pages that you visit or keep a record of your downloads (although this information could still be stored elsewhere on your system, e.g. in a list of recently opened files). New cookies received in these modes will not be saved after you close your browser, close all open incognito windows or exit guest mode. You can see when you are in incognito / guest mode because the incognito icon appears in the top corner of your browser; in some cases the border of your browser window may also change color.
When you make changes to your browser configuration, such as by bookmarking a web page or changing your settings, this information is also saved. These changes are not affected by incognito / guest mode.
In order to allow certain content to be accessed using Mustang browser for Windows, Mustang may be required to provide selected content partners and websites using Adobe Flash Access with a unique identifier that is stored on your system. You can disable this feature in the settings or reset the unique identifier’s value by reinstalling the operating system.
You may use apps, extensions, themes, services and other add-ons ("Add-ons") with Mustang, including some that may be pre-installed or integrated with Mustang and some that you may obtain from Mustang Web Store or other sources.
Before installing an Add-on, you should review the requested permissions. Add-ons may be designed to store, access, and share data stored locally or in your Drive account. Add-ons may use notifications that are sent through servers. Mustang may check for, download, and install updates to your Add-ons. Mustang may send usage indicators to for installed Add-ons. Some add-ons might require access to a unique identifier for digital rights management or for delivery of push messaging. You can disable the use of such an identifier by removing the add-on from Mustang.
From time to time, may discover an Add-on that poses a security vulnerability or violates the developer terms for Mustang Web Store or other legal agreements, laws, regulations or policies. Mustang may periodically download a list of such Add-ons from ’s servers, and may remotely disable or remove such Add-ons from user systems in its sole discretion.
