Privacy Policy
What we collect
Your name and email, the password you choose (kept only as a one-way hash), your purchase record (amount, currency, date and order number) and basic technical data such as IP address, browser, and the page or ad that brought you here. Payments are handled by Hotmart, our payment provider; we never see or store card details.
How we use it
To create your account, deliver what you bought, answer support requests, process refunds, protect the library from abuse, and learn which of our ads work. We do not sell personal data. We share it only with the services that run the site for us: Hotmart (checkout and payments), our email provider, an ad-attribution service, and the advertising platforms below, which are told that a sign-up or purchase happened. Advertising platforms receive your email only in hashed, unreadable form.
Cookies and advertising
Essential cookies keep you signed in. We also use measurement and advertising tags from Meta (Facebook and Instagram) and Google (Google Ads and Google Analytics), plus an attribution service, to see which ads lead to purchases and to show our ads to people likely to find them useful. For visitors in the European Economic Area, the UK and Switzerland, Google advertising cookies are off by default. You can block cookies in your browser, opt out of personalized Google ads at adssettings.google.com, and manage Meta ad preferences in your Facebook or Instagram settings.
Legal basis (EU and UK)
Account and purchase data are processed because they are needed to provide what you bought (performance of a contract). Usage and security logs are kept to protect the service (legitimate interest). Advertising cookies are used with your consent, which you can withdraw at any time. Our servers are outside the European Union, so your data is transferred outside the EU to provide the service.
How long we keep it
Account and purchase records are kept while your license is active and for as long as tax and accounting rules require. Sign-ups that never turned into a purchase are kept for up to 12 months, then deleted on request or during our regular clean-up.
Your rights
You can ask to see your data, receive a copy, correct it, delete it or limit its use, and you can object to processing or withdraw consent at any time, by writing to support@mechanicslibrary.com. We reply within 30 days. Residents of the EU and the UK may also complain to their local data protection authority. California residents have the same access and deletion rights under the CCPA.
