Thumpkin is a beat maker made by Sundry Mill. It is built so that almost nothing about you ever reaches us. This page says exactly what does.

Your beats and videos

Beats you make are kept in this browser's own storage on your device. The WAV and the video are made on your device too and are never uploaded. When you share a beat as a link, the whole beat is written into the part of the link after the # sign, which browsers do not send to our server, so we never see it unless you send it to us.

Sounds you record

When you tap Record, your browser asks to use the microphone. Thumpkin listens only for the two seconds of that recording, then lets go of the microphone. The sound is trimmed and kept in this browser's storage on your device, saved with your beats, and played into the videos and WAVs you make on the device. It is never uploaded, and a beat link you share does not include it.

Visits

We use Vercel Web Analytics to count visits and see which pages are used. It sets no cookies, does not follow you to other sites and gives us totals, not a profile of you. Vercel, which hosts the site, also keeps short server logs (such as the IP address and the page asked for) to run and protect the service.

Thumpkin Pro

• Payment: Pro is sold through Polar (polar.sh), our merchant of record. Polar collects your name, email address, payment details and billing country to take the payment and handle tax, under its own privacy policy. We never see your card.
• What we see: Polar shares the order with us: your email address, name, the plan, the amount and dates. We use it to unlock Pro, send your receipt, answer support and keep the records the law asks for.
• On your device: once you have paid, our server hands your browser a signed Pro pass, which it keeps in its own storage. The pass holds your plan, its end date and Polar's ids for the order, not your name or email. Your browser shows it to our server now and then so a renewed plan stays on and a cancelled one switches off.
• Receipt: your receipt comes from Thumpkin at no-reply@sundrymill.com, sent through Resend, our email provider. It carries a private link that switches Pro on in another browser; treat it like a password.
• News: the checkout has an unticked box to hear about Thumpkin and new Sundry Mill products. Only if you tick it do we add your email address to our list, and every email has a way to stop.

What we never do

No account, no tracking across sites, no advertising profiles, no selling or renting your details. Thumpkin never uses the camera, and the microphone only while you record a sound.

Your choices

You can clear everything Thumpkin keeps on your device by clearing this site's data in your browser (that also removes your saved beats, your recorded sounds and the Pro pass, which the receipt link brings back). To see, correct or delete what we hold about a purchase, or to ask anything about this page, email support@sundrymill.com. Polar's own records are covered by Polar's privacy policy.
