Privacy

Privacy isn't a setting.
It's how Latis is built.

Latis holds the most personal things you have: your plans, your money, your health. So it keeps them on your Mac, runs its assistant there too, and asks before it touches anything that matters.

Our promises

Seven things that are true every time you open Latis.

  • Your data is stored on your Mac, in a local database
  • There's no Latis account, and no Latis server holding a copy
  • Nova runs on an AI model on your own computer
  • Passwords and keys are locked in an encrypted vault
  • The microphone is on only while you hold the talk key
  • Nothing is deleted without your approval
  • Presentation Mode keeps private items out of Nova's reach
Where everything lives

In detail

What each promise actually means.

Where your data lives

Notes, tasks, events, money and health records are saved in a single SQLite database on your Mac. You don't sign up for anything, and there's no Latis cloud that your data syncs to.

How Nova handles questions

Nova runs on a free, open AI model through Ollama on your own computer. Your question, the search through your data and the answer all happen locally. Nothing is sent to an AI company.

Passwords and keys

Anything secret is kept in a vault written in Rust. It's protected with Argon2id, a password-hashing method built to resist guessing, and the macOS Keychain, and it only opens once your session is signed in.

The microphone

Voice is push to talk. The microphone is on only while you hold the talk key, and speech is processed offline. We chose not to build an always-listening mode, or even one that listens whenever Nova is open.

Approvals

Nova shows you the exact item before it deletes anything, and waits for you. When voice arrives, a spoken approval will need a clear yes plus the item's name.

Presentation Mode

Turn it on and every private item disappears from view. It's enforced in how Latis reads data, not just how it draws the screen, so Nova can't quote a private item while you're sharing.

This website

If you join the waitlist, we keep your email.

Everything else on this page is about the Latis app, which keeps your data on your Mac. This website is separate, and it stores one thing: sign-ups to the early-testing waitlist.

What we keep
Your email address, your answer to "What would you use Latis for?" if you give one, and the date and time you signed up.
Why
To email you when an early build is ready to try, and to learn what people want Latis for. We don't use it for anything else.
Where it lives
In a database hosted for us by Neon, a database provider. It is separate from the Latis app.
Your IP address
The form uses it for a few minutes to slow down bots. It isn't written to the waitlist database.

Get removed

Enter the email you signed up with and we'll delete it, along with your answer and sign-up date. It happens straight away.

What we won't pretend

Latis is a prototype, and we'd rather say so.

Latis hasn't had an independent security audit yet. Until it has, this page will say so. Everything above describes how the app is built today, and we'll update it whenever that changes.

If you spot something that looks wrong, or find a way private data could leak, please tell us straight away. We'd much rather hear it from you than find out later.
