Shop privacy and sales measurement

Sales and campaign measurement

Updated November 11, 2026. The adult-facing shop is separate from the children's learning activities. Payhip handles checkout, receipts and digital delivery. Gift recipient emails and messages are handled by Payhip. Read Payhip's privacy policy.

When you follow a labelled shop link, we carry its advertising platform, campaign, commercial and target-country label through the shop URLs to Payhip checkout. We may also include the approximate country of the checkout visit, provided by Cloudflare. This is not your billing country or precise location.

Payhip sends completed-payment and refund notifications to our Cloudflare service. We keep the order reference, purchase date, currency, amount, available processing fees, product identifiers, gift status, refund status and any verified campaign labels. Buyer names, email addresses, full IP addresses, payment-card details, gift messages and recipients are not stored in this sales-measurement database. Payhip and payment providers retain their own checkout records under their policies.

This sales system uses no analytics cookies, browser storage, fingerprinting, Google Analytics or advertising pixels. Google Analytics and the optional Google Tag Manager loader are disabled on our shop, and our Payhip Google Analytics integration is off. Payhip's separate Meta Pixel integration remains configured, subject to Payhip's checkout consent controls; this is separate from our sales-measurement database. No learning participation records are sent by the sales system.

Labels follow the current linked browsing path; purchases without a valid label remain unattributed. Shared links and later purchases may not identify the original advertising source. We omit attribution metadata when the checkout request sends Global Privacy Control or Do Not Track. You can also use an unlabelled shop URL to make an unattributed purchase.

Detailed measurement records are retained for about 13 months and then removed. They are accessible only through our authenticated Cloudflare account for sales reporting and reconciliation. They are not published or sent back to advertising platforms. This retention period applies only to these measurement records, not to separately held payment, tax or support records.
