Information we collect

We collect information you provide when you complete a form, request a resource, buy a product, subscribe to emails, or contact us. This may include your name, email address, correspondence, and order details.

Stripe processes payments and provides us with purchase-related information such as the buyer's contact details, product or payment reference, payment status, and amount. We do not receive your complete payment-card number through this checkout.

Our website and service providers may also collect technical information, including IP address, browser and device information, pages visited, and referral information. Our email platform may record email opens, link clicks, and subscription activity, depending on its settings and your email software.

How we use information

We use personal information to:

  • Process orders and deliver requested resources.

  • Provide support and respond to messages.

  • Send purchase, delivery, and other necessary service communications.

  • Send newsletters, educational content, and information about our offers where we have the required permission or another lawful basis.

  • Maintain business records, prevent misuse, and operate and improve our services.

Where UK or EU data protection law applies, our legal bases depend on the activity: fulfilling a contract or your request; complying with legal obligations; our legitimate interests in operating, supporting, and securing the business; and consent where required for marketing or tracking technologies.

We need an email address to deliver a resource by email. Providing information for delivery does not automatically constitute consent to receive marketing emails.

Providers and disclosures

We use Squarespace for website hosting, Stripe for payment processing, and Kit for email delivery and subscriber management. These providers receive or process the information needed for their services. Purchase information may pass from Stripe to Kit through our integration.

We may also disclose information to professional advisers or authorities where reasonably necessary to meet legal obligations or protect legal rights. We do not sell or rent our mailing list to other businesses for their own email marketing.

Cookies, analytics, and advertising

Squarespace and embedded services may use cookies or similar technologies for website functionality and measurement. Our website also contains integrations for Google Analytics, Meta Pixel, and Pinterest Tag. Where enabled, these tools may collect information about visits and interactions for analytics, advertising measurement, or audience targeting, and their providers may use that information under their own privacy policies.

You can manage cookies through your browser settings and any applicable choices presented on our website. Blocking some technologies may affect site functionality. Advertising and analytics choices may also be available through the relevant provider. Where consent is legally required, nonessential tracking must depend on that consent; this policy itself does not provide it.

Retention and security

We keep information for as long as reasonably needed for the purpose for which it was collected, including resource delivery, support, our subscriber relationship, and applicable accounting or legal requirements. The period depends on the type of record and those requirements.

After an unsubscribe request, we may retain a minimal suppression record to help ensure you are not added back to marketing communications. Purchase records may need to be retained separately for accounting or legal purposes.

We use reasonable organizational and technical measures to protect personal information. No online service can guarantee absolute security.

International processing

Our business is based in the United States, and information may be processed by us and our providers in the United States or other countries. Data protection laws may differ from those where you live. Applicable law may require additional safeguards for international transfers. Contact us for information about the locations and safeguards relevant to your information.

Your choices and rights

Use the unsubscribe link in a marketing email or contact us to stop marketing messages. Unsubscribing does not prevent necessary communications about an existing purchase or support request.

Depending on applicable law, you may have rights to access, correct, delete, or receive a copy of your information; restrict or object to certain processing; or withdraw consent. Contact us to make a request. We may need to verify your identity, and some records may be retained where legally required.

You may also complain to your local data protection authority. In the United Kingdom, this is the Information Commissioner's Office: https://ico.org.uk/make-a-complaint/.

Changes

We may update this policy as our practices or legal obligations change. The latest version and update date will appear on this page. We will provide additional notice where applicable law requires it.
