Do I need to make a donation for each computer I use CleanUp! on?

There is no need to donate for any of the computers you use CleanUp! on. It is freeware, meaning you can use it - and share it with others - for free. However, if you find it useful, all I ask is that you make a donation for whatever amount you feel it is worth and provided you can afford it. I have some users who are on low-income and either cannot afford to donate anything (that's fine), or only donate $5 (fine too), even though they feel it is worth more.

The main things to remember are (1) that CleanUp! is free to use for as long as you want; and (2) that I do have costs associated with making it freely available, so if you'd like to help out with those, then please make a donation as and when you can afford it, but don't feel pressured - it is still available to you for free.

Ideally companies that use CleanUp! on many of their PCs would make a donation - in cash, hardware, software or other services. However, this rarely tends to happen. Instead CleanUp! is supported by many individuals like yourself.
