Study Randomizer's specific data is stored on the Postgres database system. No data about trial contents, projects or trial subjects are stored. All data is backed up daily and backups are retained for longer periods. Additional offsite backups are taken and stored externally with variable retention periods.

When you contact support by email, we will store your email address and other contact data. These data are stored in the EU.

We might offer customized data storage options for specific customers. If that is the case, these data storage options might have different geographical locations and retention conditions. Please contact Study Randomizer if you need customized data storage.


We collect application logs for security and error analysis. These logs contain traces of your data processing.


The Study Randomizer website and support and email hosting are in the EU.
