Terms of Service

These Terms of Service (“Terms”) govern your use of the Mona Lisa application (“Mona Lisa”, the “App”) and this website, provided by Dev1tch, operated by Nika Urchadze (“we”, “us”, “our”). By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. The App

Mona Lisa is a macOS menu-bar application that uses your Mac’s camera to recognize enrolled faces and lock the screen when it cannot verify an enrolled user. All face detection and recognition run locally on your device.

2. License

Mona Lisa is proprietary software. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable license to install and use the App on Macs you own or control. A paid subscription authorizes protection on a single Mac (identified by a hashed device identifier); each additional Mac requires its own subscription.

You may not copy (except as needed to install), modify, distribute, sell, sublicense, reverse-engineer, decompile, or attempt to derive the source code of the App, except to the extent this restriction is prohibited by applicable law.

3. Subscriptions, billing, and reseller

Downloading and setting up Mona Lisa is free. An active subscription is required to keep protection running on a given Mac. Subscriptions are billed annually and renew automatically until cancelled.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Billing, tax, and payment are subject to Paddle’s Buyer Terms.

4. Acceptable use

You agree to use Mona Lisa only on devices you are authorized to secure, and in compliance with all applicable laws — including laws governing camera use, recording, and privacy in your jurisdiction. You are responsible for informing others who may be recorded by the App where the law requires it.

5. No guarantee of security

Mona Lisa is a deterrent against opportunistic, unauthorized use. It is not a replacement for full-disk encryption, a strong account password, or physical security, and it cannot guarantee prevention of access by a determined attacker. For protection against theft or forensic access, use it alongside Apple’s FileVault and a strong login password.

6. Disclaimer of warranties

The App is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or will detect every unauthorized user.

7. Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, security breach, or unauthorized access, arising out of or related to your use of the App. Our total liability for any claim will not exceed the amount you paid for the App in the twelve months before the claim.

8. Changes

We may update these Terms from time to time. Material changes will be reflected by the “Last updated” date above. Continued use of the App after changes take effect constitutes acceptance.

9. Governing law

These Terms are governed by the laws of Georgia, without regard to its conflict-of-laws rules. Any disputes will be subject to the courts located in Tbilisi, Georgia.
