JuttaMe

Use JuttaMe if you don't want your messages and conversations to catch up with you at some point. JuttaMe was developed as a European alternative to the common messenger apps. 
After three days, your messages will be automatically destroyed and permanently deleted. 
Registration is possible with a freely selectable email address without being tied to your telephone number. 
So invite your personal and important contacts via a private email address. 
A web-based login is also possible at www.juttame.com
