Does taking input of the user's Codeforces handle in a Chrome extension require a privacy policy to be published by the developer?

[Arpan]

I have build a chrome extension which is used to monitor user's and their friends codeforces rating and to fetch their rating I am taking input from user of their codeforces handle. So does it requires a privacy policy to be published by me for this?

I have not tried anything till now, just asking before publishing?

Hi there,

It is best to be open and transparent with users. Clearly explain what information you collect, how you use it, and include this information in both the Chrome Web Store and your online privacy page.
For more information, see these FAQ about user data:

Thanks,
