Privacy Policy

NexaChain provides non-custodial software that allows merchants to create digital-asset payment requests and allows buyers to review and authorize payments using self-custodied wallets.

For privacy-related questions, requests, or complaints, contact:

This Privacy Policy applies to:

• The NexaChain website.
• The NexaChain Merchant application.
• The NexaChain Buyer application.
• Payment requests, QR-code payments, and secure payment links created through NexaChain.
• Related authentication, cloud synchronization, support, and operational services.

This policy does not govern independent blockchain networks, wallet providers, blockchain explorers, Google Play, or other third-party services that maintain their own privacy policies.

NexaChain is designed as non-custodial software.

• NexaChain does not take custody of users' digital assets.
• NexaChain does not authorize blockchain transactions on behalf of users.
• NexaChain does not control user wallet balances.
• NexaChain does not have the authority to reverse confirmed blockchain transactions.
• NexaChain does not have the authority to freeze user-controlled wallets.

Information may be used to:

• Create and authenticate user accounts.
• Provide merchant and buyer application functionality.
• Create, retrieve, and synchronize payment requests.
• Display payment details before user authorization.
• Record application-level payment history.
• Confirm blockchain transaction status.
• Maintain application security and prevent misuse.
• Diagnose technical problems and improve reliability.
• Respond to support and privacy inquiries.
• Comply with applicable legal obligations.

NexaChain does not sell personal information. Information may be processed or shared in the following limited circumstances:

NexaChain may rely on services provided by third parties, including:

• Google Firebase authentication and cloud services.
• Google Play distribution services.
• BNB Smart Chain infrastructure.
• Blockchain RPC providers and explorers.
• Website hosting and deployment providers.

Each third party may process information under its own privacy policy. Users should review the policies of the relevant providers.

NexaChain uses reasonable technical and organizational measures intended to protect information against unauthorized access, misuse, alteration, loss, or disclosure.

These measures may include:

• Authenticated access to application services.
• Encrypted network communications.
• Access controls for cloud-hosted information.
• Separation of application data from private wallet keys.
• Monitoring and maintenance of application infrastructure.

No system can guarantee absolute security. Users remain responsible for securing their devices, accounts, wallet credentials, and private keys.

NexaChain retains personal information only for as long as reasonably necessary to provide the services, maintain security, comply with legal obligations, resolve disputes, and enforce applicable agreements.

Retention periods may vary depending on the type of information, the reason it was collected, and applicable legal requirements.

Public blockchain transactions cannot generally be modified or deleted by NexaChain because they are maintained independently by the blockchain network.

Users may request deletion of their NexaChain account and associated application-level personal information by contacting:

To protect users, NexaChain may request reasonable verification before processing a deletion request.

Certain information may be retained where required for legal, security, fraud-prevention, dispute-resolution, or compliance purposes.

Deleting a NexaChain account does not delete or alter public blockchain transactions.

Depending on your location, you may have rights concerning your personal information, including the right to:

• Request access to your personal information.
• Request correction of inaccurate information.
• Request deletion of eligible information.
• Object to or restrict certain processing.
• Request a portable copy of eligible information.
• Withdraw consent where processing relies on consent.
• Lodge a complaint with an appropriate authority.

Rights may be subject to legal limitations and verification requirements.

NexaChain and its service providers may process information in countries other than the country where the user is located. Where required, appropriate safeguards will be used for international transfers of personal information.

NexaChain is not intended for children under the minimum legal age required to use digital-asset and payment services in their jurisdiction.

NexaChain does not knowingly collect personal information from children in violation of applicable law. If you believe that a child has provided personal information, contact us so the matter can be reviewed.

The NexaChain website may use essential technologies required for security, performance, navigation, and basic website operation.

If optional analytics, advertising, or non-essential cookies are introduced, this policy and any required consent mechanism will be updated accordingly.

NexaChain may update this Privacy Policy as the platform, technology, legal requirements, or data practices evolve.

The updated policy will be published on this page with a revised effective date. Material changes may also be communicated through the website, applications, or other appropriate channels.
