Kudobuzz Product Reviews & UGC

This app exposes customer email addresses in your website's page source code in a manner easily accessible to automated scrapers. If you are subject to GDPR or any other data protection legislation, do not install this app.

I had to spend several hours informing affected customers and consulting with the ICO to ensure I was meeting my legal obligations as a data handler, which was incredibly embarrassing and upsetting. Fortunately no further action was required, but the situation should never have arisen in the first place.

The issue is a fundamental flaw in how the app handles customer data, not an isolated incident, as I have identified the same problem across multiple stores using Kudobuzz. It should be a straightforward fix for any competent developer, but having raised this directly with Kudobuzz I received no response whatsoever. Kudobuzz's handling of this, both the original data flaw and their complete silence when contacted, has resulted in this review. Totally unacceptable breach of merchant trust.

EDIT 22/7: It appears Kudobuzz now have decided to be dishonest about the reason email addresses were published publicly while using the app. There was absolutely no toggle or setting to "give permission" to display customer email addresses publicly, nor would I ever have set the app up in such a way. This was the very first thing I checked (and double checked) before making my complaint to them (which was ignored). If people want to read their original reply to my review, here it is:

"The previous reply has been removed from the Shopify App Store. Here's the old reply:
Thank you for bringing this to our attention, and we sincerely apologize for the concern this caused.

We take data privacy and security very seriously. After investigating, we identified and resolved the issue that was affecting email visibility in certain cases. The matter has now been addressed.

We understand how important trust is when it comes to handling customer data, and we regret any frustration this may have caused. If you have any further questions, please don't hesitate to reach out directly. We're here to help.

Best,

Does exactly what it says on the tin and support helped me with no wait. (Make sure you turn on the app embed!)

Simple to use, great!

Excellent customer service while switching from wix to Shopify! Responded quickly and clearly.

Full disclosure first that I guess I am a bit jaded as I had a poor customer experience with Kudobuzz. I went from a Wix site using this app and moved to Shopify. Kudobuzz charged me more per annum in Shopify for the same review numbers AND I ended up with less features. I use to be able to reply to great reviews and thank customers, however l lost that feature when I moved to Shopify. The next plan level up was just too much to justify for a smaller operator like me. I am on Breakfast plan so once I get to the limit of reviews it seems to be low value for money spent. I'd probably shop around next renewal if their value is not reviewed.

Bad experience. Continued to charge even after I cancelled their plan. After i flagged out the mistake, they promised to get back at the soonest, but after 3 working days, they still did not respond. After checking with them again, they mention they are prepared to only refund the latest month's charge. Do be careful installing this app, unless you dont mind having your card charged monthly (even after cancellation). App is not even very useful in the first place nor helped to bring extra sales.

We've used Kudobuzz for over 10 years. They have grown with our business and always strived to meet our needs as we grew. They feel a bit like family.

The customer service is fast and human, and the App looks great on our store.

Plus, they can't be beaten on price for the features they offer. 100% recommend.

Same issue as Glitterhound. Installed the app, upgraded to subscription...got some help initially, seems good, but now I'm having trouble actually posting to social media. It's been a week since I last emailed for support. I want to love it....

Update a week later. I got one reply with a vague excuse, essentially "we're working on it", and no response to the other parts of the problem... Now today I try to publish a review on facebook, and get this message.

Note, I have a PAID subscription. Terrible, terrible customer service.

Update: So, it seems there were growing pains, with this app, but I stuck with them, and am quite pleased with how it's functioning now overall. There are still little issues that crop up occassionally, but they actually do follow through on complaints, even if it takes awhile sometimes (other times it's very quick). All in all, I'm glad I stayed, good value for the money. Love being able to post my reviews to social media.

July 2025. Had an issue and the customer service was excellent, they fixed it for me very promptly, and in a friendly manner. Easy to work with.

I have been a customer for several years and I cannot say enough good things about this company and their customer support. They recently went above and beyond to help me and I am so grateful! Thank you again!! 10/10, and would give more stars if I could! They are super fast to offer support, and do an excellent job.

Chi was super helpful to migrate my KB App from one platform to another. She even sent me a CSV of all the reviews to make sure I wasn't missing any on the new store. This is SO Helpful!
