Your data and privacy

What stays on your Mac

Lyra keeps a few things locally so it can work and keep suggestions in your voice:

• The writing model, downloaded once.
• A local history of recent rewrites and of messages you sent, used to keep suggestions sounding like you.
• Your settings and personal dictionary.
• A log file that helps diagnose problems. It can contain snippets of text you typed, and never leaves your Mac unless you choose to send logs.

These live in ~/Library/Application Support/Lyra and ~/Library/Logs/Lyra. None of it is uploaded, synced or backed up to us.

What leaves your Mac

• Without Lyra Cloud: none of your writing. Lyra contacts our server only to sign you in, check your purchase, download the model and updates, and send usage counts (below), which you can switch off.
• With Lyra Cloud switched on: the text being rewritten, for that one request. It isn't stored and isn't used for training. The full breakdown.

Nothing you write is ever used to train any model, ours or anyone else's.

Usage counts

By default Lyra sends counts of feature use: things like app launches, suggestions accepted, the tone panel opened, the model downloaded. Each count comes with your app version, macOS version and Mac's memory size. They never include text you typed. They're linked to your account so we can tell how many people use a feature, not just how many times.

To stop them, switch off Share anonymous usage counts in Settings → General. The Privacy Policy has the full detail.

Sending logs to support

When you use Chat to founder with Send logs on, Lyra sends the recent part of its log with the text of your messages removed. It's off unless you switch it on for that message.

Deleting your data

• On your Mac: follow Uninstalling Lyra. Its “remove everything” step deletes the history, settings, dictionary, model and logs.
• Your account: email founder@heylyra.co.uk and we'll delete it, along with the usage counts linked to it.
