Our usual URL shortener is based on Google Firebase we tried to make a URL shortener that stores "ONLY" in text where no IP's are recorded as shown under picture below:
Custom Text (link text) &
URL:

Using Firebase as a main project, it lets us combine multiple domains.
So even if you would type in the same example text as the ending it would also be shown on other domains that is using this text for example.
rxe.lol/URLexample > rxextent.com
rxe.***/URLexample > rxextent.com
Using this we can allow your users to use multiple domains if forgotten or if better to redirect to the same URL
This also allows us to be very efficient in saving space and resources to follow up another projects,

Why use a URL shortener:
You can simply fit more links and content in less space with URL shorteners.
A tweet can describe and then link to a webpage in under 140 characters, while a full URL might not even come with an explanation.
Shorter URLs are becoming more and more integral to that cause.
