Important News for Mumblr Users Based in the EU

Mumblr GDPR Update

If you use the Mumblr widget, and are based in the EU (or have website visitors from the EU), you may need to take action on your site.

UPDATE: Mumblr is now updated to allow for compliance with GDPR law changes. Please update to Mumblr v1.6

Update details: A notification bar will now appear for EU-based users that have not previously accepted Tumblr's terms. A link in the notification bar directs users (in a separate tab or window) to the terms compliance page at Once terms are accepted, the Mumblr feed will display after a page refresh. 

Basic styling options for the notification bar can be found in the widget option panel. Additionally, custom text fields allow for multi-language support. Keep in mind that the notification bar will not appear if you have previously accepted Tumblr terms, or are visiting the page outside of the EU. If you have already accepted Tumblr terms and wish to test the notification in Mumblr v1.6, clear your browser's cookies or use an alternate browser.  


As part of the GDPR law changes that went into effect Friday, May 25th, 2018, updated it’s cookie policy, and now requires acceptance of it’s terms prior to viewing any Tumblr feed. Since the Mumblr widget utilizes Tumblr as the source of it's feeds, it is also impacted.

At this time, any feed from Mumblr will show up blank to visitors on an EU-based web browser, assuming that this visitor has not otherwise accepted the new terms at In order for the feed to be displayed, the visitor must visit and agree to Tumblr’s terms. This can be done by logging in, or clicking on an existing Tumblr feed; either option will present the user with terms. Once terms are agreed upon, Mumblr feeds will now be displayed as normal on that browser, on that particular machine. Update: Mumblr v1.6 now utilizes an automatic notification, with a link to Tumblr's terms.




What do I need to do to make my Mumblr feed compliant with GDPR law changes?

Simply update your widget to Mumblr v1.6. Mumblr itself requires no acceptance of terms, though since Mumblr uses Tumblr as the source of it's feed, acceptance of terms with Tumblr is required.

Does the notification display on page load, no matter what?

No. The authentication check that triggers the notification will determine whether Tumblr terms have been accepted on that browser. The notification will not appear unless Tumblr terms have not been accepted. Once accepted, the notification will not re-appear. 

Can site visitors just accept Tumblr terms on my page – without leaving?

Unfortunately not. GDPR law is very clear, and acceptance of Tumblr terms must take place at We've integrated the notification in the most seamless way possible. If the user follows the link to the Tumblr terms page, this takes place in a new tab or window, avoiding the need to use the browser back button. Refreshing the page restores the Mumblr feed after acceptance of terms. If the notification is closed without acceptance of terms, Mumblr will not display a feed. The rest of the page content will load as expected. 

Is this a temporary fix?

No. While this might not seem like the most elegant solution, it is the only option available. The GDPR laws are clear, and shortcuts cannot be made. Acceptance of terms have to take place at, since that’s where Mumblr feeds originate. so there is no possible way for us to make this happen on the same page as the Mumblr widget.

I'm not in the EU. Will my site show the notification?

Your site will only show the notification for users visiting your site on a web browser based in the EU, who have not previously accepted terms at Tumblr. So if you're in the USA, for example, USA-based visitors will not see the notification. 


We apologize for any inconvenience this has caused you. It is an unfortunate and unavoidable result of the GDPR law changes. If you have any additional questions, please reach out to our support team.
