Privacy

Hydrionis is operated by HEKNO Ltd, which is the data controller for the small amount of personal data described here. Write to privacy@hekno.co.uk about anything on this page.

There is no sign-up, no login, no profile and no form that sends anything anywhere. The site is a set of static files; reading it does not create a record here.

Analytics is configured on this deployment. It runs only if you agree, it is described on the cookies page, and you can withdraw at any time.

Hydrionis is served by Vercel, which processes ordinary server request data — the address requested, the time, an IP address, and the browser’s own user-agent string — in order to deliver the page and to protect the service from abuse. That processing is necessary for the site to work at all and happens whether or not you agree to anything else. Hydrionis does not receive those logs as an analytics feed and does not build profiles from them.

Under the UK GDPR you may ask what personal data is held about you, ask for it to be corrected or erased, object to processing, and complain to the Information Commissioner’s Office. In practice the honest answer to the first is usually “none”: without an account there is nothing here that identifies you.
