What MixRatio stores
MixRatio is a client-side web app. The calculators, mix ratios and guides are static data served to your browser, and every calculation runs on your device — the dimensions you type are never sent anywhere. Any preferences, saved projects or local prices you enter are stored in your browser's local storage on your device. They are never uploaded to us, there is no account system and no server-side database of your activity. Clearing your browser storage erases this data.
Analytics
If analytics are enabled on the production site, we use Cloudflare Web Analytics, which is privacy-first: it is cookieless, does not fingerprint visitors, and reports only aggregate, anonymous traffic (page views, referrers, country-level location). It cannot see what you calculate or identify you.
Payments
MixRatio Premium is sold through RevenueCat and Stripe. When you subscribe, your email and payment details are handled entirely by those providers — we never see or store your card information. To recognise your Premium access, an anonymous purchase identifier is stored in this browser (it also serves as your access code for restoring Premium on another device). It is not linked to your name.
No sale of data
We do not sell, rent, or share your personal information. There is no advertising and no third-party tracking beyond the aggregate analytics described above.
