How long is data saved?

I have set up our form to save the progress so that the users may return and complete the form later.  Our question is, how long is the progress saved?  Does it expire after 1 month, 6 months, a year?  

Any clarification you could give us would be greatly appreciated!

The data is saved for 90 days.

Let us know if you have any further questions.

Thank you!
