Terms of Use on the paywall scared me into thinking I had to draft a contract. Apple accepts a link to the standard EULA in the app description. Custom terms are optional. Missing terms are not.

Listing

If you use the standard EULA, put that link in the description. I learned this next to privacy URLs and terms on both surfaces.

Paywall

The purchase screen still needs a functional Terms link. Standard EULA in the listing does not hide a dead button. 3.1.2.

Decision before submit

Standard or custom, written down, URLs working on a phone. Then the checklist.
