Overview
What is a BINARYCOOKIES file? A BINARYCOOKIES file is a cookie file used by Apple's Safari web browser on macOS and iOS and by iOS apps that include embedded web views. It stores data known as "persistent cookies" that websites use to remember a user's settings, preferences, or login status across browsing sessions. BINARYCOOKIES files help websites load faster and maintain a consistent user experience by retaining information between visits.
More Information The BINARYCOOKIES file format stores details such as selected language, theme settings, login tokens, and other user-specific information. It also includes expiration dates, determining how long each cookie remains active. On iOS, each app that uses a web view (such as SafariViewController or WKWebView) typically has its own separate BINARYCOOKIES file. These files are stored in the app's private directory, while the operating system manages Safari's BINARYCOOKIES separately. NOTE: iOS apps that include embedded web views are mobile applications on iPhones and iPads that display web content directly within the app using a built-in browser window (rather than opening Safari or another external browser).

How to open a BINARYCOOKIES file
BINARYCOOKIES files are not meant to be opened. Instead, the Apple Safari web browser on macOS and iOS, as well as iOS apps that include embedded web views, reference these files.
However, users who want to extract the cookies their BINARYCOOKIES files contain can do so using the open-source Binary Cookies Reader.
