I am aware that data is downloaded to the users device and know how to secure the data with Row Owners etc… I am just curious to know what Data is actually downloaded, let’s use a Public Product Portal (using Glide Tables) as an example: There are 3 tables: -Product Table with 20 columns and 5 Lookups from the -Helper Table -Enquiry Table filled in by the User using a Contact Form on the Product Detail Page. So what is downloaded: -The complete database? -Or only the complete Product Table? -Or only fields from the Product Table used in an Collection e.g. the Table has 20 Columns and 5 Lookups but only 10 columns are used plus the 5 Lookups. Also -What if the Product Table contains 100 Product of which 50 are Offline, will these also be downloaded? -What happens to the data on the Users device, will that be deleted automatically when he closes the app? PS It seems that I posted the Topic in the wrong place, therefore this might be a duplication. ---
