Customer HubDevice offtime
The Device offtime policy configuration prevents active use of iOS and iPadOS devices for a defined period every day, e.g. at night or outside school or working hours. The configuration applies to supervised devices (see Supervised Mode / Supervision →).
Configuration
The configuration is created under Devices → Policies in an iOS policy via Add Configuration → Device offtime. The Daily offtime section contains the following settings:
| Setting | Required | Description |
|---|---|---|
| Start time | yes | Start of the daily lock period. |
| End time | yes | End of the daily lock period. Start and end time must be at least 15 minutes apart. The end time may fall on the following day, so periods across midnight (e.g. 19:30–06:30) are possible. |
| Time zone | yes | Time zone in which start and end time apply. The default value is UTC. |
| Message | yes | Text displayed on the lock screen during the lock period (maximum 200 characters). |
| Phone number | yes | Phone number displayed on the lock screen together with the message. |
The devices require a working internet connection to receive and lift the lock. Relution checks the lock periods every 15 minutes, so locking and unlocking may deviate from the specified times by up to 15 minutes.
Behavior during the lock period
At the start of the lock period, Relution updates the configuration profiles of the affected devices:
- Only the Settings app remains visible on the device; all other apps are hidden.
- In addition, screenshots, changes to accounts, passcode, device name, wallpaper, notifications and Bluetooth, manual installation of configuration profiles, erasing all content and settings as well as iCloud backup and iCloud sync (keychain, photos, documents) are prevented, among other things. Date and time are set automatically.
- The lock screen shows the Message and the Phone number in the format
Message (Tel.: Phone number)as well as the device name. - Other settings generated automatically by Relution, e.g. from an ongoing lesson or from the Relution Shared Device → mode, are not applied during the lock period.
When the End time is reached, the original settings are restored and the device is available as before.
Interaction with other configurations
- If the policy contains a Restrictions → configuration, it is extended by the restrictions listed above during the lock period; its list of allowed apps is limited to the Settings app for this time.
- If the policy contains a Lock Screen Message configuration, its content remains on the lock screen; the Message and Phone number of the offtime are then not displayed.
