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 measures which pages are read. It runs only if you agree, one answer covers every destination, and you can withdraw at any time from the cookies page. Declining changes nothing about what the site does for you.

It is sent to two places, and they are different in kind:

• HEKNO Analytics — HEKNO Ltd’s own service, on its own infrastructure. First-party and anonymous: no identifier is stored on your device, no account is involved, nothing is combined with data from other sites, and none of it is used for advertising.
• Google Analytics — a third party. It stores an identifier on your device so repeated visits count as one reader rather than several, which is the reason your agreement is needed before it loads at all.

Neither receives the address of a page you searched, or anything you typed into the search box: the search route is excluded from measurement before either of them is asked, and no query string ever leaves. Analytics data is not sold, not traded, and not used to build a profile of you. It is kept for 90 days.

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.
