NFT Sentinel End User License Agreement

Effective Date: 2026-07-01
Last Updated: 2026-07-01
Applies to Existing and New Users From: 2026-07-01

1. Scope of this EULA

For purposes of this EULA, “App” means the NFT Sentinel mobile application, including any version made available through the Apple App Store, Google Play, Solana dApp Store, or other authorized app stores or distribution channels. NFT Sentinel is an independently operated software service managed by an individual developer based in the Republic of Korea. “NFT Sentinel,” “we,” “us,” or “our” refers to that individual operator.

This EULA applies to your use of the App, including:

the mobile application distributed through the Apple App Store, Google Play, Solana dApp Store, or other authorized app stores or distribution channels;
any updates, patches, upgrades, or modified versions of the App;
any in-app features that interact with blockchain networks, wallets, APIs, or third-party services;
any content, interface, software, or functionality made available through the App.

Your use of any related website, account system, backend service, wallet-connected feature, community feature, or other online service may also be governed by our separate Terms of Service, available at:

https://nftsentinel.com/app/terms

If there is a conflict between this EULA and the Terms of Service, this EULA governs your license to install and use the App as software, and the Terms of Service govern your use of the related services.

2. License Grant

Subject to your compliance with this EULA, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the App on a compatible device that you own or control, solely for lawful purposes and in accordance with this EULA.

This license does not transfer ownership of the App to you. We and our licensors retain all rights, title, and interest in and to the App, including all intellectual property rights.

2.1 Paid Features and Entitlements

A purchase of a digital feature or subscription grants only the limited access, license, or entitlement expressly associated with that product. No purchase transfers ownership of the App, source code, intellectual property, blockchain protocol, data infrastructure, or other proprietary materials.

Access to paid features may depend on successful purchase verification, an active subscription where applicable, the app-store account used for the purchase, supported devices and operating systems, continued availability of the App and relevant services, and compliance with this EULA and the Terms of Service.

A voluntary developer-support purchase does not grant a feature entitlement unless a separate digital product expressly states otherwise.

3. License Restrictions

You must not, and must not permit any third party to:

copy, modify, adapt, translate, or create derivative works of the App except as expressly permitted by applicable law;
reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the App, except to the extent such restriction is prohibited by applicable law;
rent, lease, lend, sell, sublicense, distribute, or otherwise transfer the App to any third party;
remove, alter, or obscure any copyright, trademark, attribution, or proprietary notices in the App;
use the App to violate applicable law, regulations, sanctions rules, or third-party rights;
interfere with, disrupt, damage, overload, or impair the App, our systems, blockchain infrastructure, RPC providers, or third-party services;
bypass, disable, or circumvent any security, access control, rate limit, or authentication mechanism;
use the App for fraud, market manipulation, unauthorized wallet access, money laundering, sanctions evasion, or any unlawful transaction;

You must be at least 17 years old, or the minimum age required by applicable law in your jurisdiction, whichever is higher, to download, install, access, or use the App.

We are not responsible for losses caused by your failure to secure your device, wallet, private keys, seed phrases, passwords, or other credentials.

6. Non-Custodial Wallet Notice

The App is intended to operate as a non-custodial application unless expressly stated otherwise.

You are solely responsible for safeguarding your wallet and credentials.

7. Blockchain Transactions

The App may allow you, where supported, to view, prepare, request, initiate, or sign blockchain-related actions through a compatible wallet.

You acknowledge and agree that:

blockchain transactions are generally irreversible;

8. Third-Party Wallets and External Services

The App may interact with third-party wallets, wallet adapters, blockchain networks, RPC providers, APIs, analytics tools, error reporting tools, storage networks, bridges, token programs, NFT metadata services, or other external services.

These third-party services are not controlled by us. We are not responsible for:

errors, delays, outages, vulnerabilities, or data issues caused by third-party services;
wallet prompts, signing screens, transaction displays, or approvals handled by third-party wallet applications;

Your use of third-party services may be subject to separate terms and privacy policies provided by those third parties.

The App may, where supported, display, reference, or interact with tokens, NFTs, digital assets, blockchain accounts, wallet actions, asset transfers, send requests, or on-chain activity.

Unless expressly stated otherwise:

information displayed in the App is provided for informational purposes only;
balances, metadata, prices, transaction status, transfer status, or asset information may be delayed, incomplete, inaccurate, or unavailable;
no display of any token, NFT, digital asset, wallet action, transfer status, or transaction status constitutes an endorsement, guarantee, or recommendation;
asset transfers and send requests may be subject to wallet approval, network fees, compatibility limitations, technical limitations, fraud prevention checks, geographic restrictions, platform rules, and applicable law;
we do not guarantee the value, liquidity, transferability, availability, or future utility of any token, NFT, or digital asset, and we do not guarantee that any transfer or send request will be submitted, accepted, confirmed, successful, timely, or reversible.

The App does not provide financial, investment, legal, accounting, or tax advice. You should make your own decisions and consult qualified professionals where appropriate.

10. No Financial or Investment Advice

Nothing in the App, including any data, dashboard, token information, NFT information, transfer information, transaction interface, notification, article, chart, or message, constitutes financial, investment, legal, tax, or professional advice.

You are solely responsible for evaluating the risks and consequences of any transaction, asset, wallet interaction, or blockchain-related action.

We do not guarantee any profit, return, asset value, transaction outcome, transfer outcome, or future performance.

11. User Content and Feedback

If the App allows you to submit, upload, post, transmit, or otherwise provide content, feedback, suggestions, bug reports, comments, or other materials, you represent and warrant that you have all rights necessary to provide such materials and that such materials do not violate any law, this EULA, or third-party rights.

By providing feedback or suggestions regarding the App, you grant us a worldwide, perpetual, irrevocable, royalty-free license to use, reproduce, modify, distribute, display, and incorporate such feedback or suggestions without any obligation to compensate you.

You must not submit content that is unlawful, infringing, misleading, abusive, harmful, defamatory, obscene, fraudulent, or otherwise objectionable.

12. Intellectual Property Rights

The App, including its software, code, design, user interface, graphics, trademarks, logos, icons, text, images, documentation, and other materials, is owned by or licensed to us and is protected by intellectual property laws.

Except for the limited license expressly granted in this EULA, no rights are granted to you by implication, estoppel, or otherwise.

You must not use our name, trademarks, logos, app icons, product names, or branding without our prior written consent.

Open-source components included in the App are licensed under their respective open-source licenses. Open-source license notices are available at:

https://nftsentinel.com/app/licenses

13. Privacy

Your use of the App is also governed by our Privacy Policy, available at:

https://nftsentinel.com/app/privacy

The Privacy Policy explains what information we collect, how we use it, how we share it, how long we retain it, and what choices or rights may be available to you.

Depending on the App’s functionality, the App may process information such as public wallet addresses, passkey-related public-key authentication data, device information, app version, operating system version, analytics events, error logs, crash reports, purchase identifiers, subscription and entitlement status, receipt-validation information, support communications, and other information described in the Privacy Policy.

We do not request or store your private keys, seed phrases, recovery phrases, or mnemonic phrases.

Account deletion, the seven-day deletion grace period, account recovery during that period, inactive-account handling, data retention, deletion exceptions, and the treatment of on-chain records are described in the Terms of Service and Privacy Policy.

14. Updates and Changes to the App

We may, at any time and with or without notice:

update, modify, suspend, or discontinue the App or any part of it;
add, remove, or change features;
change supported wallets, networks, RPC providers, APIs, or integrations;
fix bugs, improve performance, or address security issues;
require you to install updates to continue using the App.

We do not guarantee that any version of the App will remain available or compatible with your device, wallet, operating system, blockchain network, or third-party service.

15. Availability and Security

We use commercially reasonable efforts to provide and maintain the App. However, we do not guarantee that the App will be uninterrupted, secure, error-free, or available at all times.

The App may be unavailable, delayed, inaccurate, or impaired due to:

device issues;
internet connectivity problems;
wallet application issues;
blockchain network congestion or outages;
RPC provider failures;
third-party API changes;
maintenance, updates, or security incidents;
force majeure events;
regulatory, legal, or compliance-related restrictions.

You acknowledge that blockchain applications involve technical, security, and operational risks.

16. Termination

This EULA remains effective until terminated.

Your rights under this EULA will terminate automatically if you breach this EULA. Upon termination, you must stop using the App and delete all copies of the App from your devices.

We may suspend or terminate your access to the App or any related services if we believe that:

you violated this EULA or applicable law;
your use of the App creates legal, security, operational, or reputational risk;
your activity is fraudulent, abusive, harmful, or unauthorized;
continued access is prohibited by law, regulation, sanctions, or platform policy;
we discontinue the App or relevant services.

Uninstalling the App, stopping use of the App, or terminating this software license does not by itself delete an account or cancel a subscription processed by an app store. Account deletion is governed by the Terms of Service and Privacy Policy. Following account deletion, public blockchain records and information that must be retained under applicable law may remain as described in the Privacy Policy.

Termination does not limit any rights or remedies available to us under law or equity. Sections that by their nature should survive termination will survive, including intellectual property, disclaimers, limitation of liability, indemnification, governing law, and dispute resolution provisions.

17. Disclaimer of Warranties

To the maximum extent permitted by applicable law, the App is provided on an “as is” and “as available” basis, with all faults and without warranties of any kind.

We disclaim all warranties, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, title, quiet enjoyment, accuracy, availability, security, compatibility, and non-infringement.

We do not warrant that:

the App will meet your requirements;
the App will be uninterrupted, accurate, reliable, secure, or error-free;
defects will be corrected;
blockchain data, wallet data, token data, NFT data, transfer data, or transaction data will be accurate or complete;
any transaction will be confirmed, successful, reversible, or timely;
the App will be compatible with every device, wallet, operating system, network, or third-party service;
any token, NFT, or digital asset will have any value, liquidity, utility, or availability.

Some jurisdictions do not allow the exclusion of certain warranties, so some of the above exclusions may not apply to you.

18. Limitation of Liability

To the maximum extent permitted by applicable law, the Operator and, where applicable, contractors, licensors, and service providers will not be liable for any indirect, incidental, special, consequential, exemplary, punitive, or enhanced damages, including:

business interruption;
transaction failure;
unauthorized wallet access;
network fees;

losses caused by phishing, malware, compromised devices, incorrect addresses, user error, or unauthorized access.

To the maximum extent permitted by applicable law, our total liability for any claim arising out of or relating to this EULA or the App will not exceed the greater of:

the amount you paid directly to us for use of the App during the three months preceding the event giving rise to the claim; or
USD 100 (or the equivalent amount in KRW).

Some jurisdictions do not allow certain limitations of liability, so some of the above limitations may not apply to you.

19. Indemnification

You agree to indemnify, defend, and hold harmless the Operator and, where applicable, contractors, licensors, and service providers from and against any claims, damages, liabilities, losses, costs, and expenses, including reasonable attorneys’ fees, arising out of or related to:

We may update or modify this EULA from time to time.

If we make material changes, we may provide notice through the App, our website, the applicable app store listing, or other reasonable means.

This version, including its account-deletion and inactive-account references, applies to existing and new users from 2026-07-01.
