How VWO Servers Handle Customer Website Data

Last updated

VWO is committed to ensuring the protection of Data subject rights by law or GDPR with specific guidelines on how to respect and fulfil user rights and privacy. This article explains how VWO servers receive and process user information of customer website and the privacy policies to secure their visitor data.

ATTENTION Note: This article does not apply to VWO website data and how it uses the information to improve website experience and offer the best possible service to its website visitors. You can view VWO Privacy Policy here.

VWO service starts working after the customer adds VWO Javascript tracking code between the head tags of the website code. When any visitor lands on a page where VWO test is running, the javascript code snippet fetches the appropriate configuration from the CDN and apply changes to the DOM/HTML element when the website loads. VWO only interfaces with the front-end of the customer’s website and does not require any access to their backend system and database.

All customer data on VWO servers are stored safely using AES 256-bit encryption, with stringent access control policies. VWO does not access customer data and all information collected by the customer shall be subject to their own privacy policies.

Through a strategically distributed Content Delivery Network (CDN) servers across 10 locations across America, Europe, and Asia-Pacific regions, VWO implements a highly scalable and fault-tolerant system. Our services are hosted on IBM Softlayer systems having EU-US Privacy Shield Certification requiring stringent security and access control policies.

VWO stores customer information until the VWO account is active and all data for expired accounts are deleted between 45 to 90 days, after the date of expiry. For accounts which expired before the GDPR date (25th May 2018), we are in the process of deleting the records. You can email us at to delete data for a specific account.
