Cookie Notice
Lunam uses cookies and similar browser storage for a small number of specific purposes. This notice explains which.
Last updated: 18 July 2026
Essential
We store your Supabase auth session cookie so you stay signed in, a language preference cookie so the site loads in your chosen language, and a currency preference cookie so prices show in your currency. These are strictly necessary and can't be turned off without breaking the site.
Analytics
We use PostHog to understand which pages people visit and where friction happens. We do not use ad-network cookies. You can opt out of analytics from the Settings page (Anonymous usage data toggle).
Payment
Stripe uses its own cookies on the checkout page (which is hosted by Stripe, not us) for fraud prevention. See Stripe's cookie notice at stripe.com.
Storage
We use browser localStorage for two things: caching your chart wheel data so the app opens quickly, and remembering the last reading you were viewing so you land back in the same place. This data stays in your browser and never leaves.
