What we protect, and how
A product whose pitch is proof has to start with how the proof itself is protected.
Your record's integrity
Every call is hash-chained: each entry cryptographically bound to the one before it. Editing or deleting any call breaks the chain visibly. You can verify this yourself, any time, on the verify page — no account needed.
Your data
We collect the minimum to run your account and we sell nothing to nobody. Your journal, drawings and results are visible to you alone. The signup uses a salted device fingerprint solely to enforce one free trial per device; only its hash is stored.
Your access
One account, one live device. A new login supersedes the old one instantly, so a leaked password cannot quietly ride along beside you. Self-served accounts activate through a single-use emailed license that expires in 24 hours and binds to one account only.
Our uptime
The engine monitors its own data feeds; when a feed dies, it stops publishing rather than guessing. A wrong call is worse than a missed one — that rule is enforced in code, not in policy.
