In some countries, if you use the Akismet Antispam service, for example, it is necessary to provide your visitors with a privacy policy. A privacy policy may also be necessary if the visitor can use the contact form or the comment function.
Tip: There are lots of templates and generators on the Internet.
You can insert them here. (Edit me!)
If you activate the CookieBanner plugin, your visitors will be able to go directly to this page in the contact form and in the comment function.
