Persist data value extension for Apps

[vanjapano]

Is there any difference when using the extension for mobile apps and trying to retrive data from a cookie on a later screen in the app (i.e. after certain condition is satisfied)

@vanjapano no, there's no difference when using the persist extension with apps; it works as you would expect.

Thanks Craig, one additional. When I store certain parameter in a cookie (i.e page number), and in the end I need the last page that the user saw, is this parameter overwritten, as every new page appears, or are they all stored in the cookie.
I would like to have the option of overwriting and to retrieve only the last (page number) seen. Does it work that way as well?
Thanks!

@vanjapano if you want to send the value from the previous page, I think the "Previous Page" extension will be best. This is similar to the persist extension, but it's designed to store the value set from the previous page. Please see documentation here and let me know if this helps: https://community.tealiumiq.com/t5/iQ-Tag-Management/Previous-Page-Extension/ta-p/13738
