# Restrictions ## 3 App Limit This limit is imposed by iOS and makes it, so apps installed with a normal apple account to your phone can only have a max of three active apps *including* the Scarlet app. ## Expiration Apps will expire 7 days after their registration, the expiration can be viewed in Scarlet by clicking the icon of the app you want to view the expiration for. You'll also see a refresh button to bring back the days to 7 days. This restriction is imposed by the mobileprovision which is required for app installs, these files are signed by apple with the certificate created with it so the **expiration can't be bypassed or modified.** ## Anisette Anisette is a somewhat unknown (specifically how they are generated) cryptography by Apple which is required for a majority of the login process with your account. Currently ScarletCloud uses an anisette server with some built-in techniques to go against the [-36607 error](/scarletcloud/overview/restrictions/36607-anisette-abuse.md). --- # 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.
