MAREA is engineered with a strict local-first privacy architecture. All birth dates, birth times, geographic locations, and client consultation records entered into the application are calculated and stored entirely inside your browser (Local Storage). No chart data is ever uploaded to our servers.
When you purchase a MAREA Pro license, your payment information (email address, billing address, and payment method) is processed directly by Gumroad, Inc. as our Merchant of Record to deliver your receipt and license key.
When you activate MAREA Pro, your license key is checked with Gumroad (directly from your browser or via our verification server on Cloudflare). Only the license key is sent; your charts and client data are never transmitted.
We use standard HTML5 Web Storage (localStorage) solely to store your app preferences, such as:
marea_pro_unlocked: Stores your Pro status locally on your device.marea_license_key: Stores your Pro license key on your device so the Pro documents can be opened.marea_language: Saves your preferred UI language (English/Japanese).marea_branding: Saves your custom salon name and logo adjustments locally.For Pro license holders, we also set one essential cookie, marea_pro_key (HttpOnly, valid for one year), which contains your license key and is used only to unlock the Pro cheat sheets and manual on marea-astro.com.
We may use Cloudflare Web Analytics, a cookieless service, to count page views and referring sites. It does not track you across websites.
You can clear this data at any time by clearing your browser's local cache.
Under GDPR and CCPA regulations, you have the right to access, rectify, or request deletion of any personal data. Because MAREA does not maintain customer databases of user chart records on our servers, full control over your client records remains entirely on your local device.
