Privacy
How we handle what you send us. This one is deliberately specific, because a vague privacy policy is not worth much.
What we collect
When you use the inquiry form or send an email, we receive the name, company, contact details and project description you choose to give us, together with any schematic, BOM or mechanical files you attach.
Visitor statistics for this site are limited to understanding traffic and do not identify individuals.
Why we collect it
This information has one purpose: to assess whether your project can be built, how, and at what cost. We do not use it for anything else.
If you leave an email address, we use it only to reply about your project.
What we do not do
We do not pass your schematic, BOM or mechanical files to third parties unless you explicitly agree — for example if you ask us to work with your fab or assembler.
We do not use your project as a case study, and we do not mention client names externally, without your written permission.
How long we keep it
Project files are deleted or archived within a reasonable period after the project closes and the release is complete, as set out in the confidentiality agreement.
Contact details from the inquiry form are kept only for project communication and any necessary follow-up.
Third parties
This site is entirely static. It uses no third-party analytics, embeds no third-party form service, and loads no external fonts or advertising scripts.
The inquiry form assembles an email locally in your browser; the page never uploads its contents to a server.
Your rights
You can ask us at any time what material we hold about you, and request correction or deletion. Send those requests to the contact details below.
