Donationware is software that is free to use, but encourages users to make a donation to the developer. Some donationware programs request a specific amount, while others allow users to determine what the program is worth and send in an appropriate donation. Some donationware programs make subtle requests for donations, such as an option in the menu bar. Others are more blatant, and may prompt you for a donation each time you open the program. Most donationware programs allow you to donate to the developer via a credit card or PayPal account.
