3. Payments: Lemon Squeezy
Purchases are processed by Lemon Squeezy, our online reseller and Merchant of Record. Lemon Squeezy collects your payment and billing details, calculates and remits sales tax/VAT, and processes that data under its own privacy policy: lemonsqueezy.com/privacy. We never see or store your full card details.
4. Processors and recipients
- Lemon Squeezy: checkout, payments, tax, order delivery.
- Email platform: [EMAIL PROVIDER, e.g. Kit / beehiiv] sends the newsletter and cheat-sheet.
- Website hosting/CDN: [HOSTING PROVIDER, e.g. Cloudflare Pages / Netlify].
- Analytics: [ANALYTICS PROVIDER, e.g. Plausible / Cloudflare Web Analytics (cookieless)].

5. International transfers
Some processors may process data outside the European Economic Area (for example in the United States). Where they do, we rely on an adequacy decision (such as the EU–US Data Privacy Framework, where the recipient is certified) or the European Commission's Standard Contractual Clauses. Contact us for details.
6. Cookies
This site sets no advertising or tracking cookies, and our analytics are cookieless. Third-party checkout and signup pages (Lemon Squeezy, our email provider) may set strictly necessary cookies under their own policies. If we ever add non-essential cookies, we will ask for your consent first. Affiliate links lead to vendor sites, which may set their own referral cookies once you arrive. See our affiliate disclosure.
7. Your rights
Under the GDPR you have the right to access, rectify, erase, restrict and port your data, to object to processing based on legitimate interests, and to withdraw consent at any time. Email [email protected]; we reply within one month. You may also complain to the Office of the Commissioner for Personal Data Protection, Cyprus (dataprotection.gov.cy) or the supervisory authority where you live.
8. Security
The site is static and served over HTTPS. We keep personal data in a small number of reputable services with access controls and two-factor authentication.
9. Changes
We will post any changes here with a new "Last updated" date. Material changes will be emailed to subscribers.
