Fixes #707

Thanks. I read your issue but I couldn't find the time to answer.

Do you think this is enough or should this perhaps be expanded similar to https://github.com/gorhill/uBlock/wiki/Privacy-policy

[HonoluluHenk]

Yes, good idea!
So would you agree with the following text?

Gesturify does not collect any data of any kind.

• Gesturify has no home server.
• Gesturify doesn't embed any analytic or telemetry hooks in its code.
• Gesturify doesn't accept donations or any other form of financing.

GitHub is used to host the Gesturify project. GitHub, Inc. (a subsidiary of Microsoft Corporation) owns GitHub and is unrelated to Gesturify.

As with uBlock: this text could be added to the wiki and the README could link to it.

I would prefer having it in the readme. Also it is called "Gesturefy" not "Gesturify" 😅

Gesturify doesn't accept donations or any other form of financing.

This is the only point that is not really true, because there is a donation page even though the money goes to charity. I would rather omit this line.

But other than that I'm happy with the text!

aw shucks, so sorry 😳

I updated the pr with proper texts.
