Is there any limit of Kurviger short link validity period? Or any other limit which leads to removal of them?
(in that case it would be useful to save the “long links”)
Gibt es eine begrenzte Gültigkeitsdauer für die Kurviger Kurzlinks? Oder eine andere Grenze, die zum Löschen von Kurzlinks führt?
(In dem Fall wäre es sinnvoll, die “langen Links” zu speichern)
When Google URL Shortener https://goo.gl stopped, it mentioned:
“all links will continue to redirect to the intended destination”
Thanks for your reply. My question was about the kurv.gr URL shortener - I could not find it in the forum, although I was sure that I had read it…
But now I found it in the Kurviger google group, they are “eternal”:
https://groups.google.com/g/kurviger/c/bo4H6cf6r9w/m/QEbc56T-BQAJ
As long as there is someone to decode them. 
Right now there are no plans to delete these links and I don’t expect they get deleted anytime soon.
If you want to make sure that you can reuse a tour planned now in 20 years, you should probably store the GPX track at a safe place.
