Contact us

One address for support, billing and data requests.

Reporting a technical problem

To help us reproduce the issue, please include:

• the file format and the question you selected on the workbench;
• the result you expected and the result you obtained;
• if a result appears incorrect, the test statistic, degrees of freedom and p value shown;
• your browser and operating system.

Please do not send your data file. It is not required to diagnose a problem, and the service is designed so that it never receives one.

Billing, invoices and refunds

Paddle processes payments as merchant of record, so receipts and invoices are issued by Paddle. For any question about a charge, include the Paddle receipt or order reference. Refund requests are handled under our refund policy.

Data requests

To request a copy, correction or deletion of the purchase record we hold, write to the address above. See the privacy policy for what is stored and why.

Feature and method requests

If the procedure you need is not currently supported, let us know. Requests are prioritised by how widely they would be used.

What we cannot assist with

We cannot advise on study design, interpret your results, or assess whether a finding is publishable. That is a statistical consultation rather than product support.
