Mind maps are saved on your device or a cloud. We recommend using Dropbox when using SimpleMind across platforms. Make as many mind maps as you want. The free editions save mind maps in a private folder on your device only.

Mac or Windows

Each time you create a new document, you name it and choose where to save it — for example on your desktop or in a folder. If you choose to save the mind map in a cloud folder, such as Dropbox or iCloud Drive, the cloud app syncs the changes with the cloud.
Make sure to install the cloud app, for example the Dropbox app.
Mac: When using iCloud Drive and SimpleMind Pro for iPhone&iPad, save mind maps in the SimpleMind folder created by SimpleMind for iPad&iPhone (the folder with the SimpleMind icon). SimpleMind for iPad&iPhone is not allowed to access any files outside that one SimpleMind folder as a security measure by Apple.

iPad&iPhone

When you first start SimpleMind Pro or used in-app purchase, SimpleMind will ask if you want to use iCloud Drive. This creates a SimpleMind folder in iCloud Drive where mind maps will be saved.
Or use one the built-in clouds (Dropbox, Nextcloud or NutStore)) to sync your mind maps, see how to.
Alternatively, store mind maps in any folder in Apple Files - meaning you can also store in a folder created by a cloud app such as OneDrive. Not all clouds apps support this. Read more.

Android

SimpleMind for Android can save mind maps in Local (special folder on your device) or the built-in cloud Dropbox. We recommend using Dropbox. See how to connect to Dropbox.

Alternatively in SimpleMind 2.5 and up use the Files explorer to store mind maps in any folder on your device. This includes folders created by a cloud app, such as Google Drive or OneDrive. Not all cloud apps may support this. See how to use the Files Explorer.
Note! The cloud app will synchronize the changes as it sees fit. Make sure to check you're working on the latest version as the cloud may simply overwrite any changes. Unlike Dropbox that saves both versions by creating a duplicate.
