The app is built on top of an open source project named Rclone. It supports leveraging an rclone.conf file to configure Enter Space with any possible Remote Cloud Account.

Enter Space lets you manually choose which remotes you have configured show up in the Files or Finder apps on your device.

Enter Space for Mac can also enable full functionality of writes and reads from some additional Remotes unsupported when running from other apple devices. Simply toggle the Mac icon at the top of the menu bar app and it can allow for access from other devices connected to your Mac's network. This feature leverages iCloud to aid in setting this up for the first time.

Security disclaimer:
This app starts up a local web server on your device. This web server implements a rolling password that changes routinely. The local web server does not utilize https between the Rclone Library and the App for communication as its designed for local network or in most cases same device communication and cannot use a certificate in a secure manner and honestly does not need a certificate given the private network access needed for communication. With that in mind any communication from the Rclone Library out to the internet will utilize whatever standard security protocols each service needs. While using the app with the Mac Remote feature does mean your data is transmitted clear text over your local network, it is up to you to ensure your local network is secure for this use case. I advise against using the local network communication on a public or share network connection unless you utilize a VPN to secure this communication.

Note: Enter Space facilitates the connection with your own supplied cloud storage accounts. Enter Space does not host or provide any cloud storage for you. Enter Space collects zero information on the usage of your cloud storage account. Enter Space is merely a bridge between your apple device files or finder apps and your configured cloud storage account. Enter Space does not implement any user information collection at all. All file transmissions occur directly from your device to your configured cloud account there is no intermediary outside of Rclone running locally on your device. While Enter Space has been actively tested and confirmed reliable for the developer's own purposes, you accept responsibility for any data loss that may result of using this app. Use at your own risk.
