Is CCleaner a one time purchase or recurring subscription?

Hi,

I just want to know if I purchase the CCleaner for windows is it a one time purchase or a recurring subscription?

Thank you in advance.

CCleaner for Windows is typically sold on an annual basis; we also sometimes offer two or three-year licenses (this will be marked in any relevant promotion).

We do not offer 'one-time purchases' of any of our products.
