Privacy

Last updated 28 July 2026

The short version. The yewee application runs entirely on your own computer. It does not identify anyone, does not store or transmit video or images, and does not contact us — including when you activate a licence. The only personal data we hold comes from buying the software or emailing us.

Who we are

yewee is produced by Colm Hewson, Ireland. For anything on this page, contact colly@letissier.ie.

What the application does with video

yewee finds and follows faces in a live video feed so it can draw graphics and produce video outputs. It is important to be precise about what that does and does not involve:

Video outputs go where you send them — over NDI on your local network, or to Syphon/Spout applications on the same computer. That traffic never reaches us.

If you use yewee to process footage of people, you decide what is filmed and what happens to the output, and you are responsible for meeting your own obligations for that footage. We never receive it, so we are neither a controller nor a processor of it.

Licence activation

Licence keys are verified offline, on your machine, using cryptography built into the application. Activating a licence sends nothing to us and works on a computer with no internet connection at all. The application stores your licence key and a locally generated machine identifier on your own computer so it can remember that it is activated.

This website

The site is a static page hosted by Vercel. There are no cookies, no analytics and no tracking scripts. Vercel keeps standard server logs (which include IP addresses) to deliver the site and guard against abuse — see Vercel's privacy policy.

Buying yewee

Purchases are handled by Lemon Squeezy, who act as the merchant of record and are the data controller for the checkout. They collect what a sale requires — name, email address, payment details and the location data needed for tax — and we never see your card details. See Lemon Squeezy's privacy policy.

From a completed purchase we keep a record of your name, email address and order reference, together with the licence key issued to you. We use it to send you your key and to help if you need it re-sent or moved to another machine. We do not use it for marketing and do not share or sell it.

Email

If you email us we keep the correspondence so we can deal with your enquiry and refer back to it later.

How long we keep things

Purchase records and issued licence keys are kept for as long as the licence is valid, and afterwards where tax law requires it. Email is kept while it remains useful for support.

Your rights

Under the GDPR you may ask us for a copy of the personal data we hold about you, ask us to correct or erase it, or object to how we use it. Email colly@letissier.ie and we will respond within one month. If you are unhappy with our response you can complain to the Irish Data Protection Commission.

Changes

If this policy changes we will update the date at the top of this page.
