The free plan is free, with no card and no expiry - it is where most people should start and where some will stay. The paid plans exist for the point at which one published widget stops being enough, and they are priced against what a single extra enquiry is worth rather than against what a widget costs.

Every paid plan comes with a 30-day money-back guarantee. Ask within 30 days of being charged and you get all of it back, without having to say why.
If you stop paying, nothing is deleted and nothing goes offline. Every widget you have published keeps working exactly where it is - the small “Powered by Widgio” line comes back, and you go back to publishing one at a time. That is the whole of it, and you are told the date before it happens.
