Dear Ivonne,
The mandatory links are:
This should help you to go on the right track.
Note: Always keep multiple copies of your seed phrase and spending password on paper stored not on a computer. Having a wallet is taking full responsibility (you are the bank). 15 k ADA is already worth to think about a hard wallet.
Second Note: There are no mobile versions for Daedalus and no give aways.
If you need more guidance feel free to ask.
With ADA we delegate we do not store (this is why I like ADA). You are free to do whatever / transfer wherever you want with your ADA. You have a onetime deposit of 2 ADA. which you will get back once you stop delegating for good.
Best,
Johann
