Privacy Policy

The short version

• LMM runs on your Mac. Your prompts, conversations and files never come to us.
• LMM has no telemetry.
• By default, LMM stores only conversation sizes, timings and app names, on your Mac. It saves message text only if you turn that on, and it is off by default.
• We hold only what we need to sell, check and support licences.
• We do not sell your data, and we do not run advertising.

Who we are

LMM (Local Model Manager) is a Mac menu bar app for macOS 14 or later on Apple silicon. This pre-release policy describes how the app is designed to handle information. “LMM” means the app and the website at localmodelmanager.com.

This policy covers the app, our website and our checkout. It does not cover the model servers you connect LMM to, which are other people’s products.

What stays on your Mac

• By default, LMM records conversation sizes, timings and app names. It uses them to show which models and context sizes fit your Mac and to find bottlenecks.
• Message text is saved only if you turn on the separate setting for it. That setting is off by default.
• Your licence key, activation token, pairing identity and paired-host fingerprints are kept in the macOS Keychain.
• Logs stay on your Mac and do not contain message text, file contents, licence keys, pairing codes or tokens.

App data lives in the folder ~/Library/Application Support/LocalModelManager/. We cannot see it.

If you turn message saving on, the text is stored on your Mac with the rest of the app’s data. LMM does not send it to us.

Where your prompts go

LMM works with Ollama, LM Studio, llama.cpp and MLX servers. A prompt goes only to the model server you choose: this Mac, a paired Mac, an endpoint you set up yourself, or a cloud model you connect. It does not pass through us.

That server’s own terms and privacy policy apply to what you send it. If you point LMM at an endpoint run by another company, read that company’s policy first. Ollama, LM Studio, llama.cpp and MLX are separate products with their own terms.

Connections LMM makes

This list describes connections made by the app. A server that receives a connection can see your IP address.

• Model and benchmark updates: the app downloads the knowledge feed to your Mac.
• Licence activation and renewal: the app sends its licence key and a hash of the Mac to the licence service. Activation renews about every 30 days; the app has up to 14 days of offline grace.
• Update checks: Sparkle checks for updates daily. You can turn automatic updates off.
• Paired Macs: paired hosts connect directly over your own network.
• Provider-policy checks: only when you start one, the app makes anonymous, read-only requests to public provider-policy pages.
• Your own local servers: the app makes read-only requests to model servers running on your Mac to show their status.

What we hold about customers

To sell, check and support licences, we hold:

• Licence ID, plan (Monthly, Annual or One-time), number of Macs (seats), term and expiry date.
• A hash of your purchase email, stored in your licence.
• Activation records, one for each activated Mac, stored as a hash of the Mac and not a raw hardware identifier.

We use this information to issue licences, check them when the app activates or renews, revoke a licence when it is refunded, and answer your emails. We do not use it for advertising or to build profiles of you.

Stripe handles your payment details. We do not see or store full card numbers.

We also keep the messages you send to [email protected] so that we can reply and, if needed, process a refund.

Our website and checkout

Our website is hosted on Cloudflare, which also runs our licence service. Like any web host, Cloudflare handles your request when you visit and sees technical details such as your IP address.

Checkout is run by Stripe Checkout. It shows the plan, price and terms before you pay, and Stripe collects your payment details under its own privacy policy. After checkout, your licence key appears on screen and can be downloaded as a .lmmlicense file. You can cancel or update a card through the Stripe customer portal.

We do not use advertising cookies or social-media tracking pixels on our website.

Who we share data with

• Stripe: payments, renewals, the customer portal and refunds.
• Cloudflare: hosting for our website and licence service.

We do not sell your data, rent it or share it for advertising, and LMM has no ads. We may disclose information if the law requires it, limited to what is required.

How long we keep data

We keep licence and activation records while a licence is active. Data on your Mac stays there until you delete it.

Stripe handles payment records under its own policies. For questions about licence and activation information, email [email protected].

Security

Your licence key, activation token and pairing identity sit in the macOS Keychain. Signatures on feeds and licences are checked on your Mac. Connections between paired Macs use TLS encryption, and the app remembers each paired Mac’s fingerprint.

We keep what we hold small: hashes instead of raw identifiers, and no card numbers. No system is perfectly secure, so we cannot promise absolute protection.

Your choices and rights

• Updates: turn automatic updates off.
• Message text: leave saving off, or turn it off again if you turned it on.
• Your Macs: use “Deactivate This Mac” in Settings to free a seat.
• App data: quit LMM, move the app to the Trash, then delete the LocalModelManager folder and the LMM items in Keychain Access to remove the data it stored there. Display preferences, such as your last screen, are kept in macOS’s standard app preferences.
• Your information: email us to ask for a copy of, a correction to, or deletion of what we hold about you. We may ask you to write from the address you used at checkout so we know it is you.

For questions about privacy or information handled by LMM, email [email protected].

Changes to this policy

We may update this policy. The “Last updated” date shows which version is current. If a change affects how we handle your information, we will make that clear on this page.
