FAQ

Common questions.

Where does the price data come from? ▾
Mintarc tracks live market prices based on actual completed sales, not retail or estimated values.
How does the wishlist and retirement alert work? ▾
Add any set to your wishlist and Mintarc will notify you when it's retiring soon — so you can grab it before it disappears from shelves and prices rise on the secondary market.
Is Mintarc affiliated with LEGO? ▾
No. Mintarc is not affiliated with, endorsed by, or sponsored by the LEGO Group. LEGO® is a trademark of the LEGO Group. Mintarc is an independent portfolio tracking tool for adult LEGO collectors.
Can I track built sets as well as sealed ones? ▾
Yes. Mintarc tracks condition separately — sealed, built mint, built good, or built fair. Each condition has its own market price so your collection value is always accurate.
Which currencies are supported? ▾
Mintarc supports USD, SGD, AUD, EUR, and GBP. You can switch your display currency at any time in the Profile settings.
Is my data private and secure? ▾
Yes. Your collection data is stored securely with row-level security — only you can access your own data. We never sell or share your personal information. See our Privacy Policy for full details.
