Persist Values between Sessions

For Local Use...

Define a persistent value

To define a value that persists between kernel sessions, use PersistentValue:

Use a persistent value

Use a persistent value as you would any symbol:

Wolfram Language code: Binarize[PersistentValue["logo"]]

The persistent value is not lost when the kernel is restarted:

Wolfram Language code: PersistentValue["logo"]

Remove a persistent value

Wolfram Language code: PersistentValue["logo"]

For Use Both on the Desktop and in the Cloud...

Define a persistent value

To define a value that persists between kernel sessions and can be used both on the desktop and in the cloud, put the value in the “Cloud” persistence location:

Use a persistent value

Use a persistent value as you would any symbol. Both desktop and cloud have access to the same persistent value:

Wolfram Language code: Binarize[PersistentValue["logo", "Cloud"]]

The persistent value is not lost when the kernel is restarted:

Wolfram Language code: PersistentValue["logo", "Cloud"]

Remove a persistent value

Wolfram Language code: PersistentValue["logo", "Cloud"]

Notes

Persistent values defined in the default location in Wolfram Cloud are not available on the desktop and vice versa.
