Blockchain development
& business privacy
1. Who this policy applies to
Quantum Soft PLT provides blockchain consultancy, smart contract engineering, decentralised application (DApp) development and related software services. This policy explains how personal information may be handled when you visit our website, discuss a project with us or work with us on an agreed development engagement.
For our own business enquiries and administration, we determine the purposes of processing. Where we handle personal information on a client’s behalf, the client’s instructions and the applicable development and data-processing agreement govern that work. A client-operated DApp or platform may have its own privacy notice.
2. Business and development information
Depending on the enquiry or agreed project scope, information may include:
- Business contacts: your name, work email, telephone number, organisation, role and correspondence.
- Project information: requirements, proposals, contracts, meeting notes and support requests.
- Development materials: source code, smart contract specifications, integration details, test data, debugging logs and deployment records, which may contain personal information.
- Technical information: IP addresses, browser details, access logs and diagnostic information supplied by you or generated by relevant service providers.
Information can come directly from you, from a client or authorised colleague, from project systems we are permitted to access, or from public blockchain records relevant to the work. Providing enquiry information is voluntary, but insufficient details may prevent us from responding or delivering the requested service.
3. Wallet addresses and on-chain information
A blockchain project may involve public wallet addresses, contract addresses, transaction hashes, network identifiers, token-related records, event logs and transaction history. These identifiers can be personal information when linked to an identifiable person; a wallet address is not a guarantee of anonymity.
On a public blockchain, information submitted in transactions or smart contracts can be visible to anyone and replicated by network participants, explorers and other services. It may remain available indefinitely. Quantum Soft cannot control those independent copies or guarantee that recorded information can be changed or erased. Visibility and retention on a permissioned network depend on its design and governance.
Project requirements should identify what belongs on-chain and what should remain off-chain. Personal or confidential information should not be placed on a public blockchain without an agreed purpose and a lawful basis. We encourage synthetic or minimised data for development and testing.
Ordinary enquiries do not require a wallet seed phrase, private key or production credential. Any signing, key-management or deployment responsibilities must be explicitly agreed for the project and handled through an appropriate secure process.
4. Client data and confidential materials
Where a client supplies personal information or permits access to its systems, we handle that information within the agreed scope and instructions. The client is responsible for establishing its authority to provide the data and the appropriate notices or permissions for its users. The respective responsibilities, access arrangements and return or deletion requirements should be set out in the project agreement.
Access to project data should be limited to authorised personnel and approved service providers who need it to deliver the work. Client personal information is not used for unrelated advertising. Confidential code, specifications and business materials are handled under the applicable confidentiality terms; ownership and intellectual property rights are governed by the project agreement.
5. Purposes of processing
Information is used as relevant to the engagement to assess requirements, prepare proposals, communicate with you, design and implement software, integrate smart contracts, test and troubleshoot systems, support agreed deployments and manage ongoing support.
It may also be used for contract and billing administration, access management, service security, dispute handling and applicable legal obligations. Processing is based on consent or another basis permitted by applicable law, as appropriate to the activity. Requests to use information for a materially different purpose require an appropriate notice or other lawful arrangement.
6. Service partners and disclosure
Information may be shared with authorised team members and relevant providers of hosting, code repositories, collaboration tools, project management, communications, diagnostics and professional services. Project subcontractors or specialist partners may receive information where authorised for their work and subject to appropriate contractual arrangements.
Blockchain RPC services, node providers and explorers may receive technical requests, wallet or contract identifiers, and transaction information when used in a project. Broadcasting a transaction to a public network makes the submitted on-chain information available beyond those providers.
Information may also be disclosed where required or permitted by law, or as necessary to address a security incident or protect legal rights. We do not sell personal information received through business enquiries or client development engagements.
7. International processing
Development teams, cloud services and other project providers may operate outside Malaysia. Public blockchain networks may distribute records across many countries. Where we arrange cross-border handling of personal information, we assess the applicable legal requirements and appropriate contractual or other safeguards for the engagement.
Public network replication cannot be restricted to a single location by this policy. A project’s architecture and data-processing terms should address this before personal information is submitted to a network.
9. Retention and deletion
Off-chain enquiry and project records are kept for as long as needed for their stated purpose, contractual commitments and applicable legal requirements. Retention of client personal information, including return or deletion at the end of an engagement, is governed by the relevant agreement and instructions, subject to lawful retention requirements.
Service providers and backups may have their own retention schedules. We can explain the arrangements applicable to your enquiry or project on request. Deleting information from systems we control does not erase information already recorded on a public blockchain or independently held by third parties.
10. Protection of information
We aim to apply safeguards appropriate to the information and project, including limiting authorised access and using secure channels for sensitive project materials. Project-specific access, credential handling and incident responsibilities should be documented in the engagement.
The hosted website uses HTTPS. Blockchain transparency and cryptographic verification do not make all connected applications, providers or off-chain systems private or secure. No transmission or storage method can guarantee absolute security. Suspected disclosure of personal or confidential project information should be reported using the contact route below.
11. Your choices and privacy requests
Subject to applicable law, you may ask about the processing of your personal information, request access or correction, withdraw consent where relevant, or seek to restrict processing or direct marketing. Requests for deletion, portability or other rights are considered where available under applicable law. We may verify your identity and explain any applicable limitations.
Withdrawing information needed for a project may affect the services we can provide. If your request relates to a client-operated DApp, contact that client first; when we act on its behalf, we assist under the applicable instructions and agreement. Requests concerning a provider’s independent records should be directed to that provider.
Any response to a request must take account of the public-network limitations described above. Information about Malaysia’s personal data protection framework is available from the Personal Data Protection Department (opens in a new tab).
