The short version: the pattern-design app runs in your web browser and keeps your patterns on your own device. Your designs are not sent to us. What we do receive is limited to: an email address if you sign up for something, a license key when you activate a purchase, a bug report if you choose to send one, and anonymous technical error reports. We don't sell data or run ads, and the only other companies involved are the ones named on this page.

What we collect

WhatWhenWhy
Email address, and name if you provide one You submit a signup form (trial reminder opt-in, "notify me" purchase-interest form, or a support/contact form) To send you the specific email you asked for — a trial reminder, a launch notification, or a reply to your question. Nothing else.
Your license key When you type it into the app to activate a purchase To confirm the key is valid and unlock the edition you bought. The app sends the key to our server, and our server checks it with Gumroad, the checkout service we use.
Your name, email, message, and an optional screenshot, plus the app version, page address and browser details Only when you press Send in the "Report a Bug or Request a Feature" window (Ctrl+Shift+B) So we can read your report and reply. It reaches us by email. Nothing is sent unless you press Send.
IP address, browser/OS info, page URL, and a randomly generated session ID Automatically, only when the app hits an unexpected error Error telemetry so we can diagnose and fix bugs. This is not tied to any account — there are no accounts.
Your bead patterns, project files, and app settings Never sent to us (unless you attach a file or screenshot to a bug report or email) These live in your browser's local storage on your own device. We have no way to see them, and no server of ours receives them.

What your browser does that we don't control

  • Libraries from a content delivery network. The app loads two open-source libraries from Cloudflare's cdnjs service: JSZip (used to make .zip files) in every edition, and Three.js (used for the 3D Preview) in Pro and Studio. When the page loads, your browser contacts cdnjs.cloudflare.com, which can see your IP address, as any website you visit can.
  • Folder backup. Pro and Studio's Enhanced Backup can save backup files to a folder you choose on your own computer (in Chrome, Edge and other Chromium browsers). Those files stay on your computer. We do not receive them.
  • Amazon affiliate links. Some supply links on this site go to Amazon with our affiliate tag, and they are marked as affiliate links. Amazon sets its own cookies when you follow one, and pays us a small commission if you buy. We are not told who bought. Amazon's own privacy notice applies on its site.
  • Checkout. Purchases are handled by Gumroad. We never see or store your payment details, and Gumroad's own privacy policy applies to what you give it.

How long we keep it

Signup emails are kept until you unsubscribe or ask us to delete them (every email we send has an unsubscribe link, or you can just email us). Bug reports are kept in our email for as long as it takes to answer and fix the problem. Error telemetry is kept in server logs for troubleshooting and rotated out over time; it's never linked back to a person.

Who we share it with

We don't sell, rent, or trade your information. These companies handle some of it for us or alongside us, each for the single purpose described above: Resend sends the emails you sign up for and delivers the bug reports you send us to our inbox, Gumroad runs checkout and confirms license keys, Cloudflare serves the two libraries, and Amazon only comes into it if you click an affiliate link.

Your choices

Every email includes an unsubscribe link. You can also just email us directly to ask what we have on file or to have it deleted. Since the app itself needs no account and no email to use, the simplest way to avoid all of this is to just not fill out a signup form — the trial and every stitch-design feature work the same either way. Our Terms & Refund Policy covers purchases.
