Senior engineers, directly on your project.

This Service Agreement (the "Agreement") is entered into between Stackzy, an engineering studio operating from the Indian Institute of Technology Bhilai, Chhattisgarh, India ("Stackzy", "we", "us", "our") and the individual or business entity that engages our services ("Client", "you", "your").

This Agreement governs all software development, AI/LLM integration, Web3 and smart contract development, system architecture, DevOps, and any related technical consulting services provided by Stackzy to the Client. It becomes legally binding upon written confirmation of engagement by both parties — including confirmation by email.

Each project or engagement will be described in a Statement of Work ("SOW"), project brief, or email confirmation that references this Agreement. In the event of conflict between an SOW and this Agreement, the SOW takes precedence for that specific engagement.

Stackzy agrees to provide technical services as described in the agreed scope document for each engagement. Our services may include but are not limited to:

• Full-stack web and mobile application development using modern frameworks
• AI and LLM integration, RAG pipelines, and machine learning system deployment
• Smart contract development, auditing, and deployment on EVM-compatible networks
• System architecture design, technical consulting, and code review
• DevOps, cloud infrastructure setup, CI/CD pipelines, and monitoring
• API design, backend development, and database architecture

Stackzy does not outsource or subcontract core deliverables. Every engineer working on a client engagement is a direct member of the Stackzy team with 2 to 4 years of production experience. The Client will always know who is working on their project and can communicate with them directly.

Any work outside the agreed scope requires a written change request. Stackzy reserves the right to decline scope changes that are impractical within the agreed timeline or that materially alter the nature of the engagement.

Unless otherwise agreed in the project-specific SOW, the following payment structure applies to all Stackzy engagements:

• 50% upfront — due before commencement of any work. This confirms the engagement and reserves engineering capacity.
• 50% on delivery — due upon delivery of the agreed final deliverables, or at the conclusion of the agreed project timeline.
• For longer engagements exceeding 4 weeks, milestone-based payment schedules may be agreed in writing.

All invoices are payable within 7 calendar days of issue. Invoices outstanding beyond 14 days may result in suspension of active work without liability to Stackzy. A late payment fee of 1.5% per month may be applied to invoices outstanding beyond 30 days.

Fees are quoted and invoiced in Indian Rupees (INR) or US Dollars (USD) as agreed at the time of engagement. Applicable taxes including GST will be added to invoices as required under Indian law. International clients are responsible for any wire transfer fees, currency conversion charges, or withholding taxes applicable in their jurisdiction.

Stackzy accepts payment via bank transfer (NEFT/RTGS/IMPS), UPI, and international wire. Payment details are specified on each invoice.

Project timelines are agreed per engagement in the SOW. Stackzy commits to reasonable best efforts to meet all agreed milestones. However, the following conditions may affect delivery timelines without constituting a breach of this Agreement:

• Delayed, incomplete, or conflicting requirements from the Client
• Failure by the Client to provide necessary access, credentials, or approvals within the agreed review period (default: 5 business days)
• Scope changes requested by the Client after work has commenced
• Technical dependencies on third-party services, APIs, or blockchain networks outside Stackzy's control
• Force majeure events including but not limited to natural disasters, government actions, or widespread infrastructure failures

In all cases where a delay is anticipated, Stackzy will provide written notice as early as practically possible, including a revised estimated delivery date and the reason for the delay. The Client is expected to acknowledge and confirm revised timelines in writing.

Intellectual property ownership is determined by payment status and the nature of the work:

Upon receipt of full payment, all custom code, designs, documentation, and deliverables created specifically for the Client as part of the agreed scope become the exclusive property of the Client. The Client receives full ownership of these materials and may use, modify, distribute, or commercialise them without restriction or further payment to Stackzy.

Stackzy retains ownership of all pre-existing tools, frameworks, libraries, reusable components, methodologies, and general-purpose utilities developed outside this engagement. This includes open-source dependencies used in the project (which remain under their respective licences), internal boilerplate code, and development infrastructure. Where such materials are included in Client deliverables, Stackzy grants the Client a perpetual, royalty-free licence to use them in connection with the delivered project.

If payment is incomplete at the time of any dispute or termination, Stackzy retains ownership of all deliverables until the outstanding balance is settled in full. Stackzy may withhold delivery of final materials until payment is confirmed.

Stackzy may reference completed engagements in our portfolio, website, and marketing materials unless the Client has entered into a separate NDA or confidentiality agreement that explicitly prohibits this.

Stackzy warrants that all services will be performed with reasonable professional skill, care, and diligence consistent with accepted industry standards. We warrant that all custom deliverables will substantially conform to the agreed specifications at the time of delivery.

All code produced by Stackzy will be: version-controlled via Git with a meaningful commit history; accompanied by documentation appropriate to the complexity of the work; written to production-quality standards unless a prototype or proof-of-concept is specifically agreed; and subject to internal review before delivery to the Client.

Stackzy does not warrant that software will be completely free of bugs, or that it will meet performance benchmarks not specified in the original scope. Stackzy provides a 14-day bug-fix period after final delivery during which we will correct defects in the delivered code at no additional charge. This warranty does not cover issues caused by Client modifications, third-party integrations outside our control, or requirements not specified in the original scope.

Stackzy's total aggregate liability to the Client for any claim arising from or related to this Agreement shall not exceed the total fees paid by the Client for the specific deliverable or milestone that is the subject of the claim. Stackzy is not liable for indirect, consequential, incidental, punitive, or special damages under any circumstances.

Both parties acknowledge that in the course of an engagement, confidential information may be shared. Stackzy will not disclose, publish, or share any confidential business information, technical specifications, unreleased product details, or proprietary data shared by the Client to any third party without express written consent, except as required by applicable law.

This obligation survives the termination of the Agreement for a period of two years from the date of last disclosure. For matters involving trade secrets, the obligation continues indefinitely.

Clients requiring a more formal or detailed confidentiality arrangement are encouraged to enter into Stackzy's separate NDA, which is available upon request at contact@stackzy.io.

Either party may terminate this Agreement with 14 calendar days' written notice. Written notice may be delivered by email to the addresses on file for each party.

Upon termination by either party: the Client will pay for all work completed and reasonably incurred expenses up to the effective termination date; Stackzy will deliver all completed work and project materials in a usable format; work-in-progress that cannot be delivered in a functional or independently usable state will be compensated at a pro-rated daily rate based on the agreed project fee; and any advance payments in excess of the value of completed work will be refunded within 14 days.

Stackzy reserves the right to terminate this Agreement immediately without notice if: the Client engages in conduct that violates applicable law; the Client has not made an agreed payment within 30 days of the due date; or the nature of the requested work is found to conflict with Stackzy's ethical standards as described under Acceptable Use.

Stackzy will not provide services for projects that: violate applicable Indian or international law; involve deceptive, fraudulent, or manipulative user experiences; facilitate the creation of malware, spyware, or other harmful software; involve content that harms, exploits, or deceives users; or conflict with Stackzy's professional and ethical standards as determined in our sole discretion.

If, during an engagement, Stackzy determines that the project conflicts with these principles, we reserve the right to suspend or terminate the engagement with written notice, and will refund any advance payment proportional to undelivered work.

This Agreement is governed exclusively by the laws of India. The courts of Chhattisgarh, India shall have jurisdiction over any disputes arising from or related to this Agreement.

Before pursuing formal legal action, both parties commit to a 30-day good faith negotiation period. Either party may initiate this period by sending a written notice of dispute to the other party. Both parties agree to engage in reasonable and good faith discussions to resolve the issue before escalating.

If the dispute cannot be resolved through negotiation within 30 days, it shall be referred to arbitration under the Arbitration and Conciliation Act, 1996 of India. The seat of arbitration shall be Chhattisgarh, India.

Entire Agreement: This Agreement, together with any applicable SOW, constitutes the entire agreement between the parties and supersedes all prior discussions, representations, or agreements relating to the subject matter.

Amendments: No modification to this Agreement is valid unless made in writing and acknowledged by both parties. Email acknowledgement is sufficient.

Severability: If any provision of this Agreement is found to be unenforceable, the remaining provisions continue in full force and effect.

Relationship of Parties: Stackzy operates as an independent contractor. Nothing in this Agreement creates an employment, partnership, or joint venture relationship between Stackzy and the Client.

Waiver: Failure by either party to enforce any right under this Agreement shall not constitute a waiver of that right.

This Non-Disclosure and Confidentiality Agreement ("Agreement") is entered into between Stackzy, operating from IIT Bhilai, Chhattisgarh, India ("Stackzy") and the individual or entity seeking to engage or already engaged with Stackzy's services ("Disclosing Party" or "Receiving Party" as applicable, collectively "the Parties").

This Agreement is mutual — both parties may disclose and both parties may receive confidential information. The purpose of this Agreement is to protect the confidential information of both parties during the evaluation, negotiation, and execution of a potential or existing business relationship, without limiting either party's ability to develop independently.

This Agreement becomes effective upon written confirmation by both parties. Confirmation by email to contact@stackzy.io constitutes valid and legally binding execution.

"Confidential Information" means any and all non-public information disclosed by one party (the "Disclosing Party") to the other party (the "Receiving Party") in connection with a business relationship or project, regardless of the form or medium through which it is disclosed — whether written, oral, digital, visual, or by demonstration.

Confidential Information includes, but is not limited to:

• Source code, software architecture, algorithms, technical designs, and engineering methodologies
• Business plans, financial projections, pricing models, revenue figures, and investment strategies
• Client lists, user data, partnership details, and commercial relationships
• Product roadmaps, unreleased features, research findings, and competitive intelligence
• System credentials, API keys, private keys, wallet addresses, and access tokens
• Personnel information, compensation structures, and organisational details
• Any information marked "confidential", "proprietary", or "not for distribution"
• Any information that a reasonable person in the industry would understand to be confidential given the context of disclosure

Information does not need to be labelled "confidential" to qualify — context and common sense determine its character.

Upon receiving Confidential Information, the Receiving Party agrees unconditionally to:

• Hold all Confidential Information in strict confidence and not disclose it to any third party without prior written consent from the Disclosing Party
• Use Confidential Information solely for the purposes of the agreed business relationship and no other purpose whatsoever
• Apply at minimum the same degree of protection used to safeguard its own confidential information, and in no case less than reasonable care and industry-standard security practices
• Restrict access to Confidential Information to only those team members who have a genuine need to know and who are themselves bound by confidentiality obligations at least as protective as those set out here
• Immediately notify the Disclosing Party in writing upon discovery of any unauthorised access, disclosure, or use of Confidential Information
• Not copy, reproduce, or summarise Confidential Information beyond what is strictly necessary for the permitted purpose
• Not reverse engineer, decompile, or attempt to derive underlying ideas from Confidential Information except to the extent expressly permitted by applicable law

The obligations in this Agreement do not apply to information that the Receiving Party can demonstrate with clear and contemporaneous evidence:

• Is or becomes publicly available through no act or omission of the Receiving Party
• Was already in the Receiving Party's lawful possession before the disclosure under this Agreement, free from any obligation of confidentiality
• Was independently developed by the Receiving Party without reference to, use of, or inspiration from the Confidential Information
• Was lawfully received from a third party who had the right to disclose it without restriction
• Is required to be disclosed by applicable law, regulation, or court order — provided the Receiving Party gives the Disclosing Party prompt written notice and cooperates with any effort to limit or contest the required disclosure

These exclusions are interpreted narrowly. The burden of proving that an exclusion applies lies entirely with the Receiving Party.

This Agreement and its obligations take effect on the date of execution and remain in force for a period of three (3) years from the date of the last disclosure of Confidential Information between the parties.

Notwithstanding the above, obligations relating to trade secrets — information that derives independent economic value from not being known and that Stackzy or the Client takes reasonable steps to maintain as secret — shall continue indefinitely until the information enters the public domain through no fault of the Receiving Party.

Termination of an underlying project or service engagement does not terminate this Agreement. Confidentiality obligations survive any termination or expiry of the business relationship.

Upon the earlier of: (a) the written request of the Disclosing Party; (b) the termination of the underlying business relationship; or (c) expiry of this Agreement — the Receiving Party shall promptly and completely:

• Return all tangible materials containing Confidential Information to the Disclosing Party
• Permanently and irreversibly destroy all digital copies, including backups, cached versions, and cloud storage copies, to the extent technically feasible
• Provide written certification that all Confidential Information has been returned or destroyed, signed by an authorised representative

The Receiving Party may retain archival copies of Confidential Information solely where required by applicable law, regulation, or internal governance requirements, provided such copies remain subject to the confidentiality obligations of this Agreement.

Nothing in this Agreement grants the Receiving Party any licence, right, or interest in any intellectual property, patent, copyright, trademark, or trade secret belonging to the Disclosing Party. All Confidential Information remains the exclusive property of the Disclosing Party at all times.

The disclosure of Confidential Information does not constitute a representation, warranty, or guarantee of any kind regarding its accuracy, completeness, or fitness for any particular purpose. The Disclosing Party provides Confidential Information on an "as is" basis for the limited purpose described in this Agreement.

Nothing in this Agreement prevents either party from independently developing products, services, or technology that may be similar to the subject matter of Confidential Information, provided they do so without using, referencing, or benefiting from the Confidential Information of the other party.

Both parties acknowledge and agree that any breach or threatened breach of this Agreement will cause immediate and irreparable harm to the Disclosing Party for which monetary compensation alone would be an inadequate remedy. In the event of breach or threatened breach, the Disclosing Party is entitled to seek immediate injunctive or other equitable relief from a court of competent jurisdiction without the necessity of proving actual damages and without posting bond.

Seeking injunctive relief does not limit the Disclosing Party's right to pursue all other available remedies including damages, legal costs, and any other relief a court deems appropriate.

This Agreement is governed by the laws of India. Any disputes arising from or related to this Agreement shall be subject to the exclusive jurisdiction of the courts of Chhattisgarh, India. Before litigation, both parties agree to attempt resolution through a 30-day good faith negotiation period.

Our website (stackzy.io) uses minimal cookies for functional purposes only — such as maintaining session state and ensuring the site works correctly. We do not use tracking cookies, advertising cookies, or third-party analytics cookies that follow you across the web.

You may configure your browser to reject or delete cookies at any time. Doing so may affect the functionality of some parts of the website but will not prevent you from accessing its core content.

We do not use fingerprinting, pixel tracking, or any other persistent identifier technology beyond standard server logs.

Stackzy operates from India. If you are located outside India and share personal information with us, your information will be transferred to and processed in India. By engaging with us, you consent to this transfer.

We take appropriate steps to ensure that international transfers of personal data are handled with care and in compliance with applicable laws, including the Information Technology Act, 2000 and the Digital Personal Data Protection Act, 2023 of India.

We may update this Privacy Policy from time to time to reflect changes in our practices, the law, or our services. Material changes will be communicated to active clients via email at least 14 days before the changes take effect.

Minor or non-material changes may be made without advance notice. The most current version of this Policy is always available at stackzy.io. Continued engagement with Stackzy after the effective date of any changes constitutes acceptance of the updated Policy.

Stackzy is a founder-led engineering studio. When you engage Stackzy, you are working with senior engineers — typically 8 to 20 years of production experience — matched to your specific technical requirements, with the founder directly involved in scoping, delivery oversight, and communication.

You will always know who is working on your project and will be able to reach them directly during the engagement. There is no account-management layer or relay chain between you and the people building your product. The founder remains your single point of accountability throughout.

Every Stackzy engagement follows a clear and transparent onboarding process designed to protect both parties and ensure that work begins on a solid foundation:

• Initial conversation: A call or exchange to understand your requirements, timeline, budget, and success criteria. No commitment is implied by this conversation.
• Scope confirmation: Following alignment, Stackzy issues a written scope confirmation outlining deliverables, timeline, team composition, and fees. This document must be approved in writing by both parties.
• Upfront payment: Receipt of the agreed upfront payment (typically 50%) is required before work commences. This confirms the engagement and reserves engineering capacity.
• Kickoff: A structured kickoff session sets expectations, confirms communication channels, and establishes the review cadence for the engagement.

Engagements do not begin on the basis of verbal agreements alone. All commitments are confirmed in writing before any work is performed.

Clear, consistent communication is a non-negotiable part of how Stackzy works. Our commitments to you:

• Responding to client messages within one business day during active engagements
• Providing written progress updates at least once per week for all active projects
• Flagging technical blockers, scope ambiguities, or risks immediately in writing — not at the next scheduled call
• Being available for scheduled calls, reviews, and demonstrations as agreed at kickoff
• Providing honest assessments of feasibility, timeline impact, and technical trade-offs without softening difficult conclusions

In return, we expect clients to:

• Designate a single named point of contact with the authority to make product decisions
• Respond to review requests and questions within the agreed review period (default: 5 business days)
• Provide complete, accurate, and consolidated requirements rather than iterative corrections across multiple messages
• Raise concerns or disagreements promptly rather than allowing them to accumulate

Communication failure is one of the most common causes of project delay. Both parties share responsibility for maintaining clear and timely dialogue throughout the engagement.

The agreed scope is the foundation of every Stackzy engagement. We recognise that requirements evolve, and we support reasonable scope changes through a structured process:

• Any requested change to the agreed scope must be submitted in writing as a formal Change Request
• Stackzy will provide a written impact assessment within 3 business days, covering the effect on timeline, cost, and technical architecture
• The change becomes part of the engagement only upon written approval from both parties
• Work on the changed scope does not begin until any additional fees are confirmed and invoiced

Verbal scope changes are not binding. An engineer agreeing informally to an additional feature in a call does not constitute a scope change. Only written, confirmed change requests are actionable.

Repeated or large scope changes that materially alter the nature of the engagement may, at Stackzy's discretion, require renegotiation of the overall project structure and fees.

Stackzy's quality standards are not negotiable downward. Every deliverable produced by Stackzy adheres to the following baseline:

• Version control: All code is managed in Git with a meaningful commit history. Commits describe what changed and why, not just what files were modified.
• Documentation: Every deliverable includes inline documentation and, where appropriate, a README or technical handover document sufficient for a competent engineer to understand, operate, and extend the work.
• Production grade: Unless a prototype or proof-of-concept is specifically agreed in writing, all code is written to production standards — with proper error handling, logging, input validation, and security considerations.
• Review process: All critical deliverables undergo internal review by at least one other engineer before being delivered to the client.
• Testing: Unit tests and integration tests will be provided where agreed in the scope. For blockchain and financial systems, test coverage is considered mandatory regardless of scope specification.

Stackzy provides a 14-day defect correction period following final delivery during which we will fix material defects in the delivered work at no additional charge. This period does not cover new feature requests, changes to requirements, or issues arising from client modifications.

A successful engagement is always a collaboration. The Client's responsibilities include:

• Providing complete, accurate, and timely requirements before and during the engagement
• Granting necessary system access, credentials, API keys, and repository permissions within 2 business days of the kickoff
• Reviewing and providing consolidated feedback on deliverables within 5 business days of delivery, unless a different review period is agreed
• Ensuring that a person with decision-making authority is reachable during the engagement
• Informing Stackzy promptly of any changes to technical constraints, business context, or requirements that may affect the work
• Not modifying, deploying, or distributing in-progress deliverables without prior discussion with the Stackzy team

Failures in Client responsibilities that cause delays or additional work will be addressed through the change request process and may affect timelines and fees.

All custom code, designs, and deliverables produced specifically for the Client transfer to the Client upon receipt of full and final payment. Stackzy retains the right to use generic frameworks, reusable utilities, and general engineering patterns from the engagement in future work.

Open-source dependencies included in deliverables remain governed by their respective licences. Stackzy provides a complete list of third-party dependencies and their licences in the technical handover documentation for every engagement.

Unless explicitly prohibited by a separate NDA, Stackzy may reference completed engagements in our portfolio and client list. We will not disclose proprietary technical or business details without explicit written consent.

Stackzy will not knowingly contribute engineering services to projects that:

• Violate applicable Indian or international law
• Facilitate financial fraud, deceptive or manipulative user experiences, or unauthorised data collection
• Involve the creation of malware, exploits, or tools designed to cause harm to third-party systems or users
• Conflict with Stackzy's professional and ethical standards, as determined in our reasonable discretion

If, during an active engagement, Stackzy determines that the project conflicts with these principles, we reserve the right to pause or terminate the engagement with written notice, and will refund any advance payment proportional to undelivered work.
