What kind of disclaimers do I need if I want to implement email signups?


I want to implement an option, where people can sign up to my email list, so I can keep them up to date with important information, new releases, etc.

What kind of disclaimer would I need? A disclaimer that pops-up at app start, or do I just put links under the sign up form to Terms of Service and Privacy Policy?

I’d appreciate your help.
