Ccleaner for Android in my own language

Can I change the language or how can I help translating the app to my own language?

Hi chr123,

CCleaner for Android's language is detected from the language you are using on your phone. If we don't have the translation for your language, then the default is English.

If you are interested in translating into your language, then please get in touch with Support @ https://piriform.zendesk.com/hc/en-us/requests/new and we can set you up on the translation platform.
