Privacy
Data controller: Fluxt Ltd. Last updated June 2026.
It runs on your device
Satura works entirely in your browser. Color identification, simulation and the color-vision test are on-device computations. Your camera feed is processed locally and is never uploaded or sent anywhere.
What we store
Your settings, saved colors and test results are kept on your own device (in the browser's storage), not on a server. Using the free core needs no account. The only time we store anything in the cloud is the optional Pro unlock, described below.
If you buy Pro (optional account)
The free core never needs an account. Pro is an optional one-time unlock. If you choose to buy or restore it, you sign in with your email (a one-tap link). We then store a small record in Google Firestore: your account ID, your email, and a flag marking whether Pro is unlocked. That's all — none of your colors, photos or test results are sent to us. You can ask us to delete this record at any time (see Contact).
Payments
Pro payments are handled by Stripe. We never see or store your card details — Stripe processes them as an independent data controller under its own privacy policy. We keep only Stripe's confirmation that your purchase succeeded, linked to your account.
Analytics
We use Cloudflare Web Analytics to understand overall usage (such as page views). It is cookie-free, does not track you across other sites, and does not collect personally identifying information.
Where we operate
Satura is operated by Fluxt Ltd from the United Kingdom, and we process the limited data described above under UK data-protection law (UK GDPR). If you buy Pro, the small account record is stored on Google Cloud (Firestore) and your payment is handled by Stripe — both may process data outside your country. Wherever you use Satura, the free core stays on your device.
