❤️ FluentCleaner is donation-supported.
Im building FluentCleaner as a donation-supported project. Learning WinUI 3 and turning this into a real app was definitely not painless, but it has been a lot of fun too.
If you like the project and want to support future releases, donations really help keep it going
