Does SpeakOut! comply with GDPR?

The plugin doesn’t need to comply, it is your site that has to meet the rules.  I have done my best based on what people have asked for.  Under dashboard > SpeakOut! > settings there is a new item at the bottom to Display Privacy Policy accept”.  If you check that box and fill in the URL to your privacy policy a checkbox will be displayed on your petition form with a link to your privacy policy.

If it needs more work (I am not in the EU) please send me a message via the contact form.
