Privacy Policy

1. Overview

GMEngine is committed to respecting the privacy of its users while providing tools for transparent, on-chain activity. This Privacy Policy explains what information we collect, how we use it, and what choices you have in relation to your data.

Because GMEngine is built on public blockchains, some information is inherently public and cannot be changed or removed once recorded on-chain. This policy primarily covers off-chain information that we may process to operate the service.

2. Data We Collect

We aim to collect only the minimum information necessary to provide and improve GMEngine. Depending on how you use the service, we may process:

• Wallet information: blockchain wallet addresses and related on-chain activity that you choose to connect to GMEngine.
• Usage data: basic information about how you interact with the app, such as visited pages, feature usage, and approximate timestamps.
• Technical data: limited device or browser information (for example, browser type, OS, and approximate region inferred from IP) used for security, performance, and analytics.
• Optional contact information: if you choose to reach out via provided channels, we may process your email, handle, or other details you voluntarily share.

We do not collect passwords, seed phrases, private keys, or other wallet credentials. You should never share this information with us or with anyone claiming to represent GMEngine.

3. How We Use Collected Data

We use collected information solely to operate, secure, and improve GMEngine, including to:

• Deliver core functionality of the app and relayer services.
• Track subscription status and execution schedules.
• Monitor service performance, reliability, and security.
• Analyze aggregated usage patterns to improve UX and features.
• Respond to support requests, bug reports, or other communications you initiate.

We do not sell or rent your personal information to third parties. Any data sharing is limited to what is necessary to provide the service (for example, infrastructure or analytics providers) and is subject to appropriate safeguards.

4. On-Chain Transparency

All blockchain transactions executed through GMEngine, whether manual or relayed, are recorded on public networks. This data typically includes wallet addresses, contract interactions, amounts, and timestamps.

Because blockchains are immutable, we cannot alter, delete, or restrict access to on-chain records. Anyone can access this information via block explorers or other indexing tools. When you use GMEngine, you acknowledge and accept this inherent transparency.

5. Cookies & Similar Technologies

GMEngine may use cookies or similar technologies to maintain sessions, remember preferences, and understand how users interact with the app.

• Essential cookies used to enable core functionality.
• Optional analytics or performance cookies used to understand aggregated usage and improve the service.

You can control or disable cookies through your browser settings, but some features of GMEngine may not function properly if essential cookies are blocked.

6. Data Security

We implement reasonable technical and organizational measures to help protect off-chain information from unauthorized access, loss, or misuse. However, no system or transmission over the internet is completely secure.

You are responsible for securing your devices, wallet software, and private keys. GMEngine cannot recover lost private keys, reverse unauthorized on-chain transactions, or compensate for asset losses caused by compromised wallets.

7. Third-Party Services & Links

GMEngine may reference, embed, or link to third-party services (for example, RPC providers, wallet connectors, analytics tools, or external websites). These third parties have their own privacy practices, which we do not control.

We encourage you to review the privacy policies of any third-party services you interact with in connection with GMEngine.

8. Data Retention

We retain off-chain data only for as long as it is reasonably necessary to provide the service, comply with legal obligations, or protect our rights. When data is no longer needed, we take steps to delete or anonymize it where feasible.

9. Your Choices & Rights

Depending on your jurisdiction, you may have certain rights regarding your personal data (for example, access, correction, deletion, or restriction). While blockchain data generally cannot be altered or removed, we will make reasonable efforts to honor applicable rights with respect to off-chain information we control.

If you wish to exercise such rights, you can contact us via the official channels listed in the application or documentation. We may need to verify your identity and the scope of your request before acting on it.

10. Children's Privacy

GMEngine is intended for use by adults and is not directed to children. We do not knowingly collect personal information from individuals under the age required by applicable law. If you believe that a child has provided us with personal information, please contact us so we can take appropriate action.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date at the top of this page. Your continued use of GMEngine after any changes become effective constitutes your acceptance of the updated policy.
