The public Houston programme has ended.

Last updated 14 September 2026

No new Houston applications are being collected.

The public founding-user programme and its enquiry form have been withdrawn. Praxis retains this address so existing links continue to resolve and former enquirers can find the relevant information.

Who is responsible for previous enquiry information.

Applied Praxis Limited, company number SC891275, trading as Praxis Lab, is the controller for personal information previously collected through the Houston enquiry form.

Registered office: 48 West George Street, Glasgow G2 1BP, United Kingdom. Contact: gs@praxis-lab.co.uk.

How previous enquiries are handled.

Information supplied through the former form was used to respond, assess whether Houston was a suitable fit, arrange a requested next step and protect the enquiry service from abuse. Praxis relied on legitimate interests to handle expected business enquiries and operate the service securely.

Enquiries are held in a private database hosted in the European Union. Access is limited to authorised Praxis personnel and infrastructure providers acting on Praxis’s instructions. Information is not sold or added to an unrelated marketing list.

Previous enquiries expire after 90 days.

Enquiries are deleted automatically from the active private database and retained deployment backups once they reach 90 days. One-hour rate-limit hashes expire separately and are not retained in backups. A confirmed deletion request removes the matching enquiry from the active database and retained backups.

Depending on the circumstances, former enquirers may ask for access, correction, deletion, restriction, portability or object to processing by emailing Praxis. These rights are not always absolute. Anyone dissatisfied with the response may complain to the UK Information Commissioner’s Office through its complaints service.

The basis on which Houston was explored.

Customers retained ownership of supplied files. Original versions were not silently edited. Praxis inspected files only where access had been agreed, and participants could request deletion of their files and related service data.
