# Supported Usage The Conectum portal is primarily designed for desktop browser usage. Certain actions, such as flashing Castrum OS, require a computer and cannot be completed on a mobile device. Mobile access is supported for basic actions such as viewing services, checking balance, and managing purchases. For actions such as flashing Castrum OS, please use one of the following browsers: * Google Chrome * Microsoft Edge * Opera * Vivaldi Note: While Brave is based on Chromium, its aggressive privacy settings may cause issues with device communication. For this reason, Brave is not recommended for the flashing process. Not Recommended: * Brave * Firefox * Safari --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
