You don't have to order a premium plan with us, even if you use your website commercially, e.g. as advertising for your nail salon, your company or your club.
But keep in mind that for commercial websites there are certain legal pitfalls to be aware of, such as a legally valid imprint. Please inform yourself about the legal regulations for your service and your country.
For the placement of advertising banners, which advertise for other sites, you need a premium package. Advertising banners for non-profit organizations are of course excluded from this regulation!
