How do you save HandyGPS walks on your phone?

I have purchased HandyGPS app for my iphone 5 for about $3 and it is working beautifully.
Only problem is that you have to download a walk onto computer and then delete from the HandyGPS before recording another walk. There does not seem to be a storage facility for previous walks - or am I missing something?
