Privacy
The calculator and saved quote history do not require an account. Quote inputs, calculated values, and saved records remain on your device and are not sent to our analytics provider.
Anonymous product analytics
The website and iOS app use PostHog for limited product-interaction events, such as landing-page views, a completed calculator interaction, App Store clicks, app opens, quote saves, live-price request outcomes, paywall views, and purchase-flow outcomes. Events may include page path, campaign attribution, app version, build number, platform, plan interval, storefront country, elapsed time, and privacy-safe error codes. We disable web session replay, person profiles, and cross-app tracking. We never send weights, karats, prices, payouts, quote history, free-form text, dates, email addresses, or your identity to PostHog.
Google Analytics
The website also uses Google Analytics 4 to measure aggregate website usage, such as pages viewed, referrer, device type, and approximate location. We do not enable advertising features or Google signals, and Google Analytics does not run for automated test traffic. See Google's privacy policy for how Google processes this data.
Operational data
Our hosting providers may process standard request information such as IP address, device/browser metadata, requested URL, and security logs to deliver and protect the service. Requesting a live reference price contacts our price endpoint, but the request contains no calculator inputs.
Support
If you email support, we receive the message and address you choose to provide so we can reply. Do not send financial account details or government identifiers.
Your choices
You can use manual-price mode without requesting a live reference price. Deleting the app removes its local records and install-scoped analytics identifier from that device. Browser controls may block or clear website analytics storage.
