Update to Trustpilot Subprocessor List - FAQs

1. Why am I receiving this email?  I'm not using Trustpilot services / I'm not a Trustpilot customer.

You have received this email because you are registered in our system as a Trustpilot business user. If you don't remember signing up to Trustpilot, it’s likely that at some point in the past your company claimed their Trustpilot profile page and is therefore designated as a free plan user. 

2. I don't want to receive these emails, can I unsubscribe?

No, you have received this email because you’re registered in our system as a Trustpilot business user. Trustpilot users can't unsubscribe from account- and service-related emails because we need to make sure you receive these important emails. If you don't want to receive any account- or service-related emails at all, you can delete your Trustpilot business account.

3. Why am I getting this email in English?

We appreciate that you may be used to using Trustpilot in a language other than English. However, we’re obliged to send this email to you in English. 

4. What are the changes?

We’ll be adding one new subprocessor to our list of subprocessors from 1st November 2025:

ClickHouse, Inc.
650 Castro St. 
Ste 120 Unit 92426
Mountain View, CA 94041
USA

Trustpilot is adding this company in order to continue improving our service offering.  ClickHouse will assist us with delivering our services, specifically the production of reporting and analytics.

5. What will ClickHouse do as part of the Trustpilot service? 

ClickHouse will help Trustpilot with delivering our services, specifically the production of reporting and analytics on review invites which are made available to customers via their Trustpilot account.  

6. Where is the new subprocessor based? 

ClickHouse Inc. is a US headquartered company which will be the entity acting as the subprocessor, however, ClickHouse Cloud allows Trustpilot to configure a location for their data hosting. As a result, Trustpilot has elected that data hosting will be within the EEA. The new subprocessor will comply with our high security and privacy standards and we have entered into a data processing agreement with them which impose at least the same data protection obligations, as imposed on Trustpilot in section 25 of our Data Processing Agreement.

7. Does Trustpilot have a Data Processing Agreement in place with the new subprocessor? 

Yes, Trustpilot has gone through a rigorous exercise to onboard the new subprocessor and has put in place an agreement and Data Processing Agreement (“DPA”) to ensure that the service is compliant to all applicable data protection laws e.g  GDPR. ClickHouse, Inc. is signed up to the Data Protection Framework (‘DPF’) list. You can check this by searching for the ClickHouse, Inc. entity on the DPF list, found via this link. The DPF is a valid transfer mechanism under EU laws. 

8. What action do I need to take / what do I need to do?

You do not need to take any further action.

The updates to the subprocessor list will apply with effect from 1 November 2025. Please let us know if you have any specific questions or concerns regarding this change by reaching out to our Privacy team: privacy@trustpilot.com. If you have any questions about your account with Trustpilot, feel free to reach out to the Support team via the online contact page or through your Customer Success Manager (if you have one).

9. Do these changes apply to me? / Who will these changes apply to?

The updates to the subprocessor list will apply to all business customers who are using one of Trustpilot’s automatic or manual review invitation methods and whose data processing by Trustpilot is governed by our Data Processing Agreement. The ClickHouse subprocessor will only process data for certain review invitation methods.

ClickHouse will only process and store metadata associated with the following review invitation methods:

• Automatic Feedback Service (AFS)

• File Upload

• Integrations 

• Trustpilot API 

The addition of ClickHouse will not impact any other review invite methods other than those listed above.  If you are not sure which review invitation method you are using, please contact your Customer Success Manager (if you have one) or reach out to the Support team via their online contact page.
