Privacy Policy

Maestri, by Evercraft Labs · Last updated: October 17, 2026

Our Philosophy

Maestri is built with a simple principle: your data is yours. Maestri collects no analytics, telemetry, or personal information, except what license activation needs (section 5) and, if you turn them on, Maestri Remote notifications (section 7). Maestri runs entirely on your computer, whether that’s a Mac, a Windows PC, or a Linux machine, and what happens on your computer stays on your computer.

1. Data Collection

We do not collect any data. Specifically, Maestri does not collect, store, or transmit:

Personal information (name, email, location, or identifiers)
Usage data or analytics
Telemetry or diagnostics
Crash reports
Keystroke or input data
File contents, project data, or source code
Network traffic data
Device identifiers or fingerprints
Cookies, tracking pixels, or similar technologies

The only exception is license activation, described in section 5.

Maestri contains no analytics SDKs, no tracking frameworks, and no telemetry infrastructure. There are no servers receiving data from the application.

2. Local Storage

All data created and managed by Maestri, including workspaces, canvas layouts, notes, preferences, and configuration files, is stored locally on your device. This data never leaves your computer through Maestri.

You are solely responsible for backing up your local data. Maestri is not responsible for data loss resulting from hardware failure, operating system issues, or any other cause.

3. Ombro, On-Device AI Companion

Ombro is Maestri’s built-in AI companion. Ombro is powered by Apple’s Foundation Models framework and runs entirely on your device using Apple Intelligence.

Key points about Ombro:

All AI processing happens locally on your Mac. No data is sent to external servers by Ombro.
Ombro does not store conversation history beyond the current session unless you explicitly save it.
Ombro's capabilities, behavior, and on-device processing are provided by Apple through the Foundation Models framework. The privacy practices of Apple Intelligence are governed by Apple's Privacy Policy.
Evercraft Labs does not control, monitor, or have access to any data processed by Apple's Foundation Models on your device.
Ombro requires a Mac with Apple Silicon and macOS with Apple Intelligence enabled. The availability and behavior of Apple Intelligence features are determined solely by Apple.
Ombro is available only in Maestri for macOS. Maestri for Windows and Linux includes no AI features of its own.

4. Third-Party Coding Agents and CLI Tools

Maestri provides a canvas interface to organize and manage terminal sessions. Users may choose to install and run third-party command-line coding agents within these terminal sessions, including but not limited to Claude Code (Anthropic), Codex CLI (OpenAI), Gemini CLI (Google), Qwen Code (Alibaba), OpenCode, Goose, Cline CLI, and any other command-line tool.

Important disclaimers regarding third-party tools:

Maestri does not install, bundle, or distribute any third-party CLI tools. Users install these tools independently and at their own discretion.
Maestri does not intercept, read, modify, or store any data transmitted between the user and third-party CLI tools. Terminal sessions operate as standard terminal processes of your operating system (macOS, Windows, including WSL, or Linux).
Each third-party tool has its own privacy policy, terms of service, and data handling practices. The data you input into a coding agent, including source code, prompts, and project files, may be transmitted to external servers operated by the respective provider.
Evercraft Labs is not responsible for the data collection, processing, storage, or privacy practices of any third-party tool used within Maestri's terminal sessions.
It is the user's sole responsibility to review and understand the privacy policies and terms of service of any third-party coding agent or CLI tool they choose to use.

We strongly encourage users to review the privacy policies of the tools they use:

5. License Verification and Activation Data

If you purchase a Maestri license, the transaction is processed by Stripe. During the purchase process, Stripe collects payment and billing information directly. Evercraft Labs does not have access to your full payment details (such as credit card numbers).

A license works in Maestri for macOS, Windows, and Linux, and activation is the same on all three. When you activate your license, we store the following data:

Your email address, used solely for license recovery
Your license key
A device ID that your operating system assigns to this computer (on Linux, a hashed form of it), used solely to count how many devices you have activated
Your computer's name, as set in your system settings, so you can tell your activated devices apart

The device ID is used only to keep your license within the allowed activation limit. It is never used for tracking, analytics, or advertising, and it is never shared with third parties. When you deactivate Maestri on a device, the app sends your license key and that activation’s ID so the seat is freed. No other data is collected during activation or deactivation.

For details on how Stripe handles your data, please review their privacy policy.

6. Application Updates

On macOS, Maestri uses the Sparkle framework to check for application updates. When checking for updates, Sparkle may transmit your current application version, your macOS version, and your system architecture (e.g., Apple Silicon).

On Windows and Linux, Maestri uses electron-updater to check for updates. It downloads the release file for your operating system and architecture (e.g., x64 or arm64) from our update server and, when an update is available, the matching installer. These requests indicate only your platform, your architecture, and the current application version.

This information is used solely to determine whether an update is available and to serve the correct version. No personal data or device identifiers are transmitted.

On every platform, you may disable automatic update checks in Maestri’s preferences at any time.

7. Network Connections

Maestri connects to our servers only for:

License activation and deactivation (when you activate or deactivate a device).
Update checks (periodic, can be disabled).
Maestri Remote push notifications (only if you turn them on).

Some features make network connections on your behalf, but none of them send data to us:

Maestri Remote runs a server on your computer. Your phone connects to it directly over your local network or a VPN such as Tailscale. That connection never goes through our servers; only notifications do.
Portals load the websites you open in them, like any browser.
Git integration runs git and your host's own CLI (such as gh or glab) with your existing login, talking directly to your git host.
Remote environments connect to the SSH hosts, Docker containers, and runtimes you configure.

Notifications reach your phone through a small relay we run, because only Apple and Google can deliver them. Each one is encrypted on your computer and can only be read by your phone; the relay, Apple, and Google never see its content. The relay stores nothing, and to deliver it only handles your phone’s push token (on Android, Google also receives a Firebase installation ID). You can turn notifications off at any time in Maestri Remote.

All other network activity comes from third-party tools you choose to run in terminal sessions, and is governed by those tools’ privacy policies.

8. Children’s Privacy

Maestri is not directed at children under the age of 13 (or the applicable age in your jurisdiction). We do not knowingly collect any personal information from children, as we do not collect personal information from anyone.

9. Intellectual Property and Redistribution

Maestri is proprietary software owned by Evercraft Labs. All rights reserved. You may not copy, modify, distribute, sell, or lease any part of the application; reverse-engineer, decompile, or disassemble the application; remove, alter, or obscure any proprietary notices; redistribute the application in any form; share, transfer, or sublicense your license key; or use the application for any purpose that violates applicable laws.

A valid license grants a single user the right to use Maestri on their own devices. The license is non-transferable unless explicitly authorized by Evercraft Labs in writing.

10. Disclaimer of Warranties and Limitation of Liability

Maestri is provided "as is" and "as available" without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. Evercraft Labs does not warrant that the application will be uninterrupted, error-free, or free of harmful components. Use of the application is at your own risk.

To the maximum extent permitted by applicable law, in no event shall Evercraft Labs be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, use, goodwill, or other intangible losses, arising out of or in connection with your use of or inability to use Maestri; any third-party tools, services, or content accessed through Maestri; any data loss or corruption; any unauthorized access to or alteration of your data; any actions or outputs produced by AI features, including Ombro; or any conduct of third parties in connection with the application.

You acknowledge that coding agents and AI tools may produce inaccurate, incomplete, or unintended outputs. You are solely responsible for reviewing, testing, and validating any code, content, or actions generated or suggested by such tools. Evercraft Labs assumes no liability for damages resulting from reliance on AI-generated output.

11. Indemnification

You agree to indemnify, defend, and hold harmless Evercraft Labs from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable attorneys’ fees) arising from your use of the application, your violation of this Privacy Policy or any applicable terms, your use of any third-party tools or services within Maestri, or any violation of applicable laws or regulations in connection with your use of Maestri.

12. Governing Law

This Privacy Policy shall be governed by and construed in accordance with the laws of the Federative Republic of Brazil, without regard to its conflict of laws provisions. Any disputes arising under or in connection with this Privacy Policy shall be subject to the exclusive jurisdiction of the courts of Brazil.

13. International Users

Maestri is developed in Brazil and distributed globally. If you are accessing or using Maestri from outside Brazil, please be aware that the application operates locally on your device. The license, update, and notification services run on Cloudflare, payments on Stripe, and notifications are delivered by Apple and Google, so this data may be processed outside Brazil. However, third-party tools you choose to use may transfer data to servers in other jurisdictions. Please review the relevant third-party privacy policies for details.

14. Your Rights

The only personal data we hold is your license email and activation details (section 5); you can ask to access or delete it at hello@themaestri.app. If you believe we have inadvertently collected any information, please contact us and we will promptly investigate and take appropriate action.

Under applicable data protection laws (including GDPR, CCPA/CPRA, LGPD, and others), you may have certain rights regarding personal data. Because Maestri collects so little, there is very little to request.

15. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. If we make material changes, we will notify users through the application or our website. Your continued use of Maestri after any changes constitutes acceptance of the updated policy.

16. Open Source Components

Maestri may include open-source software components, each governed by their respective licenses. A list of open-source components and their licenses is available within the application under Settings > Acknowledgements.

17. Contact
