I once read that there are cookies that can stay on the computer for a long time, such as a few days, weeks or months, and that they can't be removed with Delete Chronicle.
How can one then completely remove such cookies from computers (cell phones, PCs, laptops, etc.)?
Is there some kind of software for that?
Clear browser data
I don't think you can delete the cookies
And that you can't remove them with Delete Chronicle.
In the web browser you will find the item for data protection and security in the settings. There you can make settings for cookies and delete the existing ones.
Cleanup tools like CCleaner can also kill stubborn cookies.
You can delete all cookies in the privacy settings of most browsers. The DuckDuckGo browser on Android and iOS also has a function with which you can delete all browser data immediately. If you want to regularly delete your cookies on your smartphone, this browser is recommended.
