I was also confused by this when looking at your pricing page: https://singlelink.co/pricing/

My thought process: "Oh, they'll show ad-network ads on the free tier, I guess that's OK. How much is the tier that removes ads?" and then I couldn't find a tier that mentioned it.

I think it'd be much clearer if the free tier said something like "shows Singlelink watermark/logo", and the next tier up said something like "no Singlelink watermark/logo"
