Data Controls

What you can do

You have full control over the data Lyra holds about you. This page explains how to access, export, or delete it.

What Lyra knows about you

Lyra stores very little:

• Your email address (from Google sign-in)
• Your subscription status and renewal date
• Account creation timestamp

Alongside that, we hold usage telemetry linked to your account: feature-event names and daily counts, app version, macOS version, your Mac's RAM size, and which local model tier you're on. It never includes what you type, your keystrokes, your document content, or the names of the people you write to. It is on by default and you can switch it off in Lyra → Settings → Privacy → Share anonymous usage counts. The Privacy Policy sets it out in full.

We do not store anything you type or anything Lyra rewrites.

Your corpus of sent messages, any voice profiles Lyra has derived from it, and your settings live on your Mac in ~/Library/Application Support/Lyra/. We hold no copy of them. You can delete all of it at any time by deleting the app, or by clearing the folder by hand. If you switch voice profiles on, a small sample of your sent messages for one contact is sent for classification and the resulting label is stored back on your Mac; the sample itself is not kept on our servers. How Lyra uses the cloud describes that in full.

View your account data

Open Lyra → Settings → Account. You'll see the email address linked to your account and your current subscription status.

To request a complete export of the data we hold about you in a machine-readable format, email founder@heylyra.co.uk with the subject "Data Export Request". We respond within 30 days.

Delete your account

To delete your account and all data we hold about you:

1. Open Lyra → Settings → Account → Sign out
2. Email founder@heylyra.co.uk with the subject "Delete My Account" from the email address linked to your Lyra account
3. We confirm deletion within 7 days; full removal from backups completes within 30 days

If you have an active Pro subscription, cancel it first via the customer portal (Settings → Manage subscription). Account deletion does not automatically issue a refund — see Terms for refund policy.

Local data

Lyra stores some data only on your Mac:

• The model file: ~1-3GB in ~/Library/Application Support/Lyra/models/
• Your corpus of sent messages: a SQLite database in ~/Library/Application Support/Lyra/events.db. This is a record of messages you actually sent, in your own words; messages Lyra rewrote are excluded from it.
• Voice profiles: the register label and keep-words Lyra has derived for each person you write to, cached alongside the corpus
• Settings and preferences: in ~/Library/Preferences/com.lyra.app.plist
• Logs: in ~/Library/Logs/Lyra/

Deleting the app deletes all of this. Everything Lyra has learned about how you write lives on your Mac, so removing Lyra removes it — there is nothing to request from us.

To remove all local Lyra data by hand, quit Lyra, then run in Terminal:

rm -rf ~/Library/Application\ Support/Lyra/
rm -rf ~/Library/Logs/Lyra/
rm -f ~/Library/Preferences/com.lyra.app.plist

Voice profiles: view, correct, and delete

Open Lyra → Settings → How Lyra sees your writing. For every person Lyra has built a profile for, you can:

• View it — the register it has settled on and the words it thinks are characteristically yours
• Correct it — if it has you wrong, say so and it changes
• Turn it off for that one person — Lyra stops learning from, and writing in, that voice
• Delete it — the derived profile goes

You can also turn voice profiles off entirely in Settings, which stops any further classification. How Lyra uses the cloud explains what classification sends and how often.

Local-Only mode

Local-Only mode disables Lyra's cloud features: cloud rewrites and voice-profile classification. With it on, nothing you write is sent anywhere — Lyra uses only the on-device model, and everyday corrections carry on working exactly as before, offline included.

Local-Only mode does not by itself switch off usage telemetry. Telemetry has its own switch — Settings → Privacy → Share anonymous usage counts — and is described in the Privacy Policy. It never contains what you type.

Website cookies

This one is about the website rather than the app. heylyra.co.uk asks once whether Reddit's advertising pixel may set a cookie, so we can see which Reddit ads actually bring people here. Until you accept, it is never loaded; decline and it never runs at all.

Accepting also lets us report those same visits and downloads to Reddit from our server, which is how ad measurement survives an ad blocker. That report carries your user agent, the ad's click identifier and a hashed copy of your IP address — no email, no account details, nothing you have written.

To change your answer later, use the Cookies link at the foot of any page. The site's own page-view analytics set no cookies whatsoever. Both are described in Cookies and the website.

What we do not collect

Lyra does not collect:

• The text you type
• The rewrites Lyra produces
• Keystrokes or screen recordings
• The names of applications you use Lyra in
• The names of the people you write to
• Anything that would let us identify which messages you write or who you write them to

We do collect usage telemetry linked to your account — feature-event names and daily counts, app version, macOS version, RAM size, and local model tier. It is set out in full in the Privacy Policy, contains none of the above, and can be switched off in Settings → Privacy → Share anonymous usage counts.

If we ever widen what we collect, we will announce it on this page, in the Privacy Policy, and via email to your account address before any new data is collected.

Subprocessor access

Three of our subprocessors hold a copy of your account data:

• Supabase stores your email, subscription status, and renewal date
• Google holds the original identity record (since you sign in with Google)
• Stripe holds your payment and billing details

Deleting your Lyra account removes the records held by us in Supabase. To delete your data held by Google or Stripe directly, see their respective account portals.
