CalcuLEGO Privacy Policy
Last updated July 27, 2026
CalcuLEGO is a LEGO collection, trade, and value calculator that uses BrickLink market data to estimate item values and organize saved collections.
What this site stores
If you use the calculator without signing in, normal calculator entries stay in your browser session unless a feature explicitly says otherwise. If you sign in with Google, the site uses Supabase authentication to identify your account and can save settings and personal LEGO collections to that account.
Google sign-in
Google is used only to authenticate your account. The site may receive basic account information supplied through the sign-in process, such as your name, email address, profile image, and a unique account identifier. The site does not receive or store your Google password.
Saved account data
Signed-in data can include calculator preferences, business offer settings, theme rules, collection names, collection items, quantities, condition descriptions, recorded purchase prices, and the values associated with those saved items.
BrickLink data
The calculator requests catalog and market information from BrickLink to provide valuations. Server-side caching is used to reduce repeated requests. Account collection data is not sent to BrickLink as a personal profile.
Security and access
User-owned database records are protected with account-based database access rules. Server-only credentials used for protected infrastructure are not exposed to the browser.
Exporting or deleting your data
Signed-in users can export their saved account data from Settings. The Settings page also provides an account deletion option. Deleting the account removes the authentication account and user-owned records configured to cascade with it.
Changes
This policy may be updated as the site adds or changes account features. The date at the top of this page will be updated when material changes are made.
