This website uses Plausible Analytics, a privacy-friendly analytics tool. Plausible does not use cookies, does not collect personal data, and does not track you across websites or devices. All data is aggregated and no individual visitors can be identified. We measure overall trends in website traffic such as page views, referral sources, and country-level location.
To keep the website fast and reliable, we also collect anonymous technical measurements (such as page load times and error reports) on our own servers. These reports do not contain personal data and are automatically deleted after 90 days.
This website does not use tracking cookies. If you create an account or use interactive features, we store data in your browser's local storage: a login token to keep you signed in, an anonymous session identifier for community matching contributions, and your building progress per set. This data stays on your device and is only sent to our servers to provide these features.
Creating an account is optional and only requires an email address, which we use solely to send you sign-in links and to associate your favorites, collection, and contributions with your account. We do not sell or share your email address, and we do not send marketing emails. You can delete your account at any time from your account page, which permanently removes your personal data; any community contributions are then made anonymous.
If you request a set or contact us and choose to leave an email address, we use it only to notify you about that request or to respond to your message. If you contact us, we may receive your email address, which we will only use to respond to your message.
Part images and set data may be loaded from external sources including the LEGO Group and Rebrickable. These services may have their own privacy policies. We recommend reviewing their respective privacy policies if this is a concern.
