§ Legal · Disclaimer

Disclaimer — Unofficial Third-Party Tool

VaultMTG is an independent, unofficial companion tool for Magic: The Gathering Arena (MTGA). VaultMTG is NOT affiliated with, endorsed by, or sponsored by Wizards of the Coast LLC or Hasbro, Inc. Use of VaultMTG does not affect your relationship with Wizards of the Coast or your MTGA account. “Magic: The Gathering,” “Magic: The Gathering Arena,” and all associated card names, game mechanics, set names, and artwork are the intellectual property of Wizards of the Coast LLC.

§ 1

1. Agreement to Terms

By accessing and using the VaultMTG Service — including the web application at app.vaultmtg.app, the desktop application, and all related services — you agree to be bound by these Terms of Service (“Terms”). If you do not agree, do not use the Service.

The Service is provided by Ray Hamilton Engineering, LLC, a Georgia limited liability company (“Ray Hamilton Engineering,” “we,” “us,” or “our”).

Eligibility. You must be at least 13 years old to use this Service. By using VaultMTG, you represent that you meet this requirement and have the legal capacity to enter into this agreement.

§ 2

2. Service Description

VaultMTG is a companion application for Magic: The Gathering Arena that provides:

Real-time match tracking and historical match analytics
Draft advisor powered by machine learning
Deck building, deck management, and deck analytics
Card collection management and tracking
Meta-game statistics and trend analysis
Personalized recommendations (wildcard crafting suggestions, archetype insights)

How it works — the desktop application and log files. The Service includes a desktop application that you install on your own computer. The desktop application reads MTGA game log files stored locally on your own device (the same log files that MTGA generates as you play). The application does not modify the MTGA game client, inject code, or interact with MTGA’s network traffic. It reads files from your MTGA installation directory only.

Collection import — default and optional modes. Importing your MTGA card collection has two modes:

Manual import (default). You export or paste collection data on your own and provide it to the Service. This is the default behavior and requires no elevated privileges.
Enhanced mode (opt-in). You may opt in to an enhanced collection-import mode that reads collection data directly from the MTGA process. Enhanced mode requires a one-time admin authorization on your device and operates under a least-privilege model (it does not run as root and does not install a persistent privileged service). You will be asked to consent to enhanced mode via a plain-language dialog before it is enabled; you may revoke it at any time from the application’s Settings.

Current Beta Status.The Service is in closed beta, available by invitation only. Features, pricing, and availability are subject to change without notice during the beta phase. The Service is provided “as-is” and may be modified or discontinued at any time, with or without notice.

§ 3

3. User Accounts and Registration

3.1 Account Creation

To access the Service, you must create an account via email, Google, Apple, or Facebook using our authentication provider (Clerk). You are responsible for:

Maintaining the confidentiality of your account credentials
Preventing unauthorized access to your account
Immediately notifying us of any unauthorized account access

3.2 Account Responsibility

You are solely responsible for all activity that occurs under your account. We are not liable for any loss or damage from unauthorized access to your account.

3.3 Account Suspension or Termination

We may suspend or terminate your account if you:

Violate these Terms
Engage in fraudulent, abusive, or harmful conduct
Attempt to interfere with or disrupt the Service

You may request account deletion at any time via the in-app account-deletion control where available, or by contacting us at the email in Section 18. See Section 9.

§ 4

4. The Desktop Application and MTGA Log Access

4.1 What the Application Does

The VaultMTG desktop application:

Reads MTGA log files (Player.log on macOS; output_log.txt on Windows) from your local MTGA installation directory
Parses match events, draft events, collection data, and inventory data from those logs
Transmits the parsed, structured data to VaultMTG servers over an encrypted connection (HTTPS/TLS)
Runs as a background service on your device while you play MTGA

The application does NOT:

Modify any MTGA files or game data
Inject code into or intercept network traffic from the MTGA game client
Access files outside your MTGA installation directory in its default mode
Access any files on your device unrelated to MTGA
Run with elevated/root permissions in its default mode

The optional enhanced-mode collection import described in Section 2 requires a one-time admin authorization and reads from the MTGA process; it runs under a least-privilege model and does not install a persistent privileged service.

4.2 Your Responsibility for Local Machine Security

You are responsible for maintaining the security of your local machine. We are not responsible for breaches of your device’s security that expose your MTGA log data or VaultMTG account credentials.

4.3 MTGA Terms of Service — Your Obligation

Your use of MTGA is governed by your own agreement with Wizards of the Coast and is independent of VaultMTG. It is your responsibility to ensure your use of VaultMTG is consistent with your MTGA Terms of Service.

§ 12

12. Dispute Resolution

12.1 Informal Resolution

Before initiating formal legal proceedings, you agree to contact us at the email in Section 18 and attempt in good faith to resolve the dispute informally within 30 days.

12.2 Governing Law

These Terms are governed by the laws of the State of Georgia, USA, without regard to conflict-of-law principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

12.3 Binding Individual Arbitration

Please read this section carefully. It affects your legal rights.

Any dispute, claim, or controversy arising out of or relating to these Terms or to your use of the Service (a “Dispute”) will be resolved by binding individual arbitration rather than in court, except as set out in Section 12.5 (Small Claims) and except for claims that cannot be arbitrated as a matter of law.

The arbitration will be administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules then in effect. The arbitration will be conducted by a single arbitrator. The seat of arbitration is Atlanta, Georgia, and proceedings may be conducted in person, by phone, or by video at the arbitrator’s reasonable discretion. The arbitrator’s award is final and binding on the parties and may be entered as a judgment in any court of competent jurisdiction. You and Ray Hamilton Engineering, LLC each waive any right to a jury trial.

12.4 Class-Action Waiver

YOU AND RAY HAMILTON ENGINEERING, LLC AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate more than one person’s claims and may not preside over any form of representative or class proceeding. If this class-action waiver is found unenforceable as to a particular claim, that claim (and only that claim) shall proceed in court, and the remainder of this Section 12 shall remain enforceable.

12.5 Small-Claims Carve-Out

Either party may bring an individual claim in a small-claims court of competent jurisdiction, instead of arbitration, so long as the claim remains in that forum and is brought only on an individual basis.

12.6 Opt-Out

You may opt out of this arbitration agreement and class-action waiver by sending written notice within 30 days of the date you first agree to these Terms to legal@vaultmtg.app. The notice must include your full name, the email associated with your VaultMTG account, and the statement “I opt out of the arbitration agreement and class-action waiver.” If you opt out, this Section 12 (other than the governing-law provision in Section 12.2) does not apply to you.

12.7 Survival

Sections 12.3, 12.4, 12.5, and 12.6 survive termination of these Terms.

§ 13

13. Changes to These Terms

We may update these Terms at any time. We will notify you of material changes by:

Posting a notice on the Service or website
Sending an email notification for significant changes

Your continued use of the Service after any modification constitutes your acceptance of the updated Terms.

§ 14

14. Beta-Tester Confidentiality

Keep this information confidential
Not disclose it to competitors or unauthorized third parties

This obligation survives termination of your account for 2 years.

§ 16
