Does the Safe automatically close if I do not use the device for a long time?

Set up yourself when the Safe closes automatically:

Mac
1. Menu – > Settings – > Security
2. Click on the Lock
3. Enter your password
4. Now you can change your security settings

iOS
1. – > Settings – > Security
2. Now you can change your security settings

The settings apply automatically to all safes.
SimpleumSafe for iOS uses screen protection when in background.
