Why it's different

Most finance apps tell you what happened.

Zelli helps you understand
what happens next.

Security

Your money is yours.
So is your data.

Zelli is built privacy-first. Your data lives on your device by default and is encrypted where it matters — never packaged up and sold on.

On your device by default

Your data lives on your device. Nothing leaves it unless you choose to turn on backup.

Encrypted vault

Sensitive entries in your vault are encrypted on your device with AES-GCM (256-bit), unlocked only by your passphrase.

Zero-knowledge backup

Optional, and off by default. Turn it on and everything is encrypted before it leaves your phone — we only ever hold an unreadable blob, with no account.

Never sold

We never sell or rent your personal information. Full stop.

Private by default

Reviews

No testimonials yet — and we won't fake them.

Zelli only just launched. Rather than put words in strangers' mouths, we'd rather earn a real review from you. If it helps, say so on the store — if it doesn't, tell us at support@zelli.app.

FAQ

Good questions.

No — and that's deliberate. Zelli doesn't need access to your bank to be useful. You enter what matters to you, and Zelli does the organising, understanding and planning. No open-banking permissions, no third party pulling your transactions.
Zelli is privacy-first by design. Your data lives on your device by default, not on our servers — so there's nothing central for us to lose, share or sell. Sensitive entries in the vault are encrypted on your device using the Web Crypto API (AES-GCM 256-bit, with a PBKDF2 key derived from your passphrase), and that passphrase is only ever held in memory — we never see it. Backup is optional and off by default; if you switch on cloud backup, your data is encrypted on your phone before it's sent, so the server only ever holds an unreadable blob with no account attached. As with any app that holds personal information, it's still worth keeping a passcode or biometric lock on your device, and choosing a strong, memorable vault passphrase (if you lose it, we can't recover your vault — that's the point).
Yes — your data belongs to you and nothing is locked in. You can export a backup file at any time and import it on a new phone, so moving devices is simple. There's also an optional, end-to-end encrypted cloud backup: it's off by default, needs no account, and encrypts everything on your device first — you keep a recovery code and passphrase, and the server only ever stores an unreadable blob. Turn it on for peace of mind, or leave it off and keep everything strictly on your device.
Yes — it's here. Zelli is available now on both the App Store and Google Play, free to download on iPhone and Android.
Yes — and properly so. Zelli is free to use, private by design, and will never show you ads or sell your data. There's no premium tier hiding the useful bits behind a paywall, and nothing competing for your attention — just a calm, honest place to look after your money.
