End-to-end encrypted · anonymous by design
Elafi is always-there support for the moments between therapy sessions — or before you're ready for one. Built so that privacy isn't a promise we make, but a property of the architecture: we couldn't read your words if we wanted to.
No email. No real name. A handle and a passphrase are all it takes.
Most apps protect your data with promises. Elafi protects it with mathematics and architecture — every component sees only the minimum it needs to help you.
Everything you write is encrypted on your device with keys derived from your passphrase. Our servers hold scrambled bytes. A subpoena, a breach, a curious employee — all get the same unreadable noise.
Before anything reaches a model, your device strips names, places, and identifiers and sends only the smallest slice needed — one entry, a few recent messages. You can inspect exactly what leaves, every time.
No email, no real name — an account is a key, not an identity. Deleting your account destroys the keys, which makes every stored byte permanently meaningless, even in old backups.
A companion that listens like a good therapist reads the room — reflective, warm, never rushed. Heavier moments are automatically routed to the most capable model.
Write freely, track your mood, and — only when you ask — get a short reflection on a single entry. You approve exactly what's shared first.
Mood trends, recurring themes, streaks — computed entirely on your device. Zero of it is uploaded, ever.
A library of CBT, DBT, ACT and grounding exercises, matched to how you're doing — locally, from theme tags and mood scores alone.
Elafi is a wellbeing companion, not a medical device, not a licensed therapist, and not a crisis service. It complements professional care — it never replaces it. If you're in crisis, contact the 988 Lifeline (call/text 988 in the US) or findahelpline.com anywhere in the world. And because we hold no recovery data: if you lose your passphrase and recovery key, your data is gone — that's the price of real privacy, and we'd rather be honest about it.
