We do not sell personal data, share reader lists with advertisers, or run behavioural advertising or third-party ad trackers.

You do not need an account to use the unit converter, download a template or read a policy document.

We collect your name and email when you create a reader account, which issues you open, messages you send us, standard server logs, and order details when you buy something. Passwords are stored hashed, never in plain text.

Cookies are limited to sign-in, your reading position, the shopping basket and interface preferences. All strictly necessary or functional; no analytics are running at present.

Magazine PDFs are held in a directory that is not reachable from the web and streamed only to a signed-in reader, one request at a time, through a single-use token. Paid template files are held the same way.

You can ask for a copy of your data, a correction, deletion, restriction, portability, or to withdraw consent. We answer within 30 days and do not charge.
