Privacy
Last updated 12 May 2026
Short version: Systema stores what it needs to run, sends prompts to a few well-known services, and doesn't sell your data.
What we collect
- Your email address (from Google sign-in)
- Your Google profile name and avatar (so the app knows what to display)
- Design systems, voice briefs, and generated profiles you create
- Per-account usage counters (the voice-generation cap)
How we use it
To operate the service — sign you in, save your work, generate voice profiles when you ask. We also use PostHog (EU-hosted) to log product events tied to your account so we can see how the product is being used and where it's getting stuck. No ad targeting, no email marketing.
Who we share it with
Systema relies on a handful of trusted services:
- Anthropic — receives your voice brief to generate the profile. Subject to Anthropic's privacy policy.
- Unsplash — receives a short image query (e.g. “mountain studio”) to find a photo. No personal data.
- Supabase — stores your account, projects, and usage counters.
- Google — handles sign-in via OAuth.
- Vercel — hosts the app.
- PostHog — receives product-usage events (pageviews, clicks, voice generations) tied to your email. EU-hosted.
We don't sell or rent your data to anyone. We don't use your content to train models.
How long we keep it
Until you ask us to delete it. Email pascaljb@proton.me and we'll remove your account and associated data.
Cookies
Two first-party cookies: one keeps you signed in, the other lets PostHog attribute events to the same browser session. No tracking pixels, no third-party ad networks.
