What we collect

Only what you type into a form on this site, such as your name, email address and message, the files you upload with an order, and the email you send us directly. We don't use advertising trackers or analytics cookies on this site.

How we use it

To reply to you and, if you asked to be notified or signed up, to send the emails you asked for. You can unsubscribe or ask us to stop at any time.

Who processes it

The site is hosted by Cloudflare, which processes form submissions, any files you upload, and standard server logs. Form submissions and uploaded files are deleted after 60 days. Payments are processed by Stripe; we never see or store your card number. Our email is hosted by Lark. Fonts are served from this site's own domain, and the site sets no cookies, so your browser doesn't contact Google or any other outside service just by visiting. We don't sell or rent personal information.

AI tools

We use AI tools in our work with settings that keep your information from being used to train AI models.

AI chat assistant

The chat assistant on this site is an AI, and it says so. It loads only when you click “Ask our AI assistant” and accept its terms; until then your browser doesn’t contact the service that runs it. What you type is processed by ElevenLabs, which runs the assistant, and by the AI model it uses. We keep chat transcripts for 90 days so we can check the answers, then they’re deleted. The order page also offers an optional voice intake. If you click “Start voice intake” and accept its terms, what you say is processed by ElevenLabs and the AI model it uses to fill in the form for you to check. We keep the transcript for 90 days and don’t keep recordings of your voice. Please don’t share card numbers, passwords or other sensitive details in the chat. Once you open it, the assistant may save a small note in your browser, such as that you accepted its terms.

Your choices

Email [email protected] to see, correct or delete what we hold about you. We reply within 30 days.
