Since it’s free, what’s the business model? Please state that clearly on the homepage. I usually avoid anything that’s free and doesn’t seem to have a business model (however hazy or crazy the model might sound to some).
Your privacy piece says “We are deleting data as soon as it is no longer relevant.” Please expand on this. I didn’t understand what “no longer relevant” means. Do you delete events after the date has passed? Or do you delete the RSVPs alone? When exactly do the deletions happen? It’s fine if you haven’t completely figured this out yet. But saying vague things isn’t a good idea in general.
