Hi Siva,
Is the data that will be stored inside the app be secured ?
Yes
- Can some other developer access my source code or client data being in PE/Free Edition ?
No only if you share your username/password that would be possible.
Furthermore if you create applications with role anomynous that will be available for the whole world.
If you apply a role, than users need to login with a valid username and password
- Can i publish the app in my brand and logo in IOS/Android App store without paying? If not, can i send the apk file to the clients for installation. Would that conflict with the Outsystems compliance ?
You can publish a mobile app from your PE to Google and Apple store without any additional OutSystems costs.
However to publish to stores you need to have google / apple developer accounts and those cost money.
- Can i delete old data if i see slowness in the app ?
Yes, you can as already mentioned by João Marques, you can use the Forge component
