What is the time-limit for whatsapp message to be secure in their server while offline? I know whenever I delete my Whatsapp app on my Android device, I get all the messages till I install again......

What is the time-limit for this?

What if I reinstall Whatsapp after a year? Will I get all messages for being-offline-time?

Thanks!
According to my knowledge the message will be there for 30 days.Please refer the article attached in the link.
