Image processing
Images selected in the pattern maker are processed locally by code running in your browser. The application does not upload source images or generated pattern data to our server or to the payment provider. Temporary browser object URLs display local files and stop working when released, refreshed, or closed.
Checkout and payment data
When you choose a paid export, our server creates a checkout with Creem. Creem may receive the checkout product, price, currency, request identifiers, contact and billing details you provide, payment method data, IP address, browser information, and other information needed to process the transaction, prevent fraud, calculate tax, provide receipts, and meet legal obligations. Payment details are entered directly with Creem; this site does not receive or store your full card number.
After checkout, our server verifies the signed return and retrieves the payment status from Creem. We use checkout, order, product, price, currency, and status identifiers to decide whether export access should be granted. These identifiers do not contain your image or generated chart.
Essential cookies
The paid export flow uses short-lived, HttpOnly cookies. A pending-payment cookie binds the browser to the checkout it started, and an export-access cookie records a verified temporary entitlement. These cookies are required to prevent an unverified browser response from unlocking downloads. They are not used for advertising or cross-site profiling and expire automatically.
Ordinary web requests
As with most websites, the hosting provider may receive technical request data such as IP address, browser user agent, requested path, timestamp, and security logs. This data supports delivery, abuse prevention, and debugging and is governed by the selected hosting provider's terms.
Analytics
The current code does not install an analytics service, advertising tracker, or marketing pixel. If analytics or advertising is added, this policy and any required consent controls must be updated before collection begins.
Downloads
PNG and PDF pattern files are generated in your browser and downloaded to the location controlled by your browser or operating system. The site and Creem do not receive copies of those files.
Contact
If you send an email, the message and address are handled by the configured mail provider and retained as needed to answer the request, prevent abuse, or meet legal obligations. Do not send sensitive images unless they are necessary for support.
Changes
The effective date above will change when this policy is revised. Material changes to image handling, accounts, payment providers, analytics, advertising, or storage will be reflected here before release.
