Terms of Service
Last updated: 22 September 2026
These Terms of Service ("Terms") govern (a) your use of the vaizen.dev website, including the project brief form, and (b) the provision of custom software development, UI/UX design, technical consulting and audits, and support and maintenance services (the "Services") by VAIZEN, OsOO (a limited liability company organised under the laws of the Kyrgyz Republic, registration number 225289-3301-OOO, TIN 01412202310122), Tynystanova St., Office 38, Pervomaisky District, Bishkek, Kyrgyz Republic ("we", "us", "our", or "the Company").
By using the website, submitting a brief, or engaging us for Services, you agree to these Terms together with our Privacy Policy, Cookie Policy, Acceptable Use Policy, and Refund Policy (collectively, the "Agreement"). If you do not agree, do not use the website or engage our Services.
These Terms apply to all users worldwide. Where a Statement of Work is agreed for a specific engagement, Section 2 governs how it interacts with these Terms.
Nature of services
We provide custom software development, UI/UX design, technical consulting and audits, and support and maintenance services, together with the vaizen.dev website through which prospective clients can submit a project brief. Our clients are mainly businesses; some may be individuals. We do not guarantee any particular business outcome from the Services beyond the deliverables and specification agreed in writing.
Engagement, proposals, and statements of work
Services are provided under a written proposal or Statement of Work ("SOW") agreed between you and us, setting out the scope, deliverables, timeline, fees, and any project-specific terms. Where a SOW conflicts with these Terms, the SOW prevails in respect of that engagement; in all other respects, these Terms continue to apply. Submitting a brief through our website does not, by itself, create a contract; a contract is formed only when we both agree a proposal or SOW in writing.
Client responsibilities
You agree to: provide accurate project requirements and materials; provide timely access to systems, environments, and personnel reasonably required for us to perform the Services; provide feedback and approvals within the timeframes agreed in the SOW; and ensure that materials you provide to us, and your use of deliverables, comply with applicable law and do not infringe third-party rights. Delays caused by your failure to meet these responsibilities may extend delivery timelines and are not treated as a breach by us.
Change requests
Changes to the agreed scope must be requested in writing. We will assess the impact on timeline and fees and confirm any change in writing, including by email, before implementing it. Work outside the agreed scope may be charged separately or handled under a new SOW.
Fees and invoicing
5.1 Fees are set out in the applicable proposal or SOW and may be structured as a fixed price with milestones, or on a time-and-materials ("T&M") basis.
5.2 An engagement may require an upfront deposit before work begins, as stated in the SOW.
5.3 Invoices are payable within 7 days of the invoice date ("net 7"), in the currency stated in the SOW, unless otherwise agreed in writing.
5.4 Fees are exclusive of taxes unless stated otherwise; you are responsible for any applicable taxes, duties, or withholding, other than taxes on our net income.
Late payment
If an invoice is not paid when due, we may charge interest on the overdue amount at a reasonable commercial rate, and we may suspend work, access to deliverables, or ongoing support until payment is received. We will give you reasonable written notice before suspending.
Acceptance of deliverables
Where a SOW provides for acceptance testing, you have 10 business days from delivery to review a deliverable and notify us in writing of any material non-conformance with the agreed specification. If you do not notify us within that period, the deliverable is deemed accepted. Where a notified non-conformance is confirmed, we will correct it and redeliver within a reasonable time, after which this procedure repeats for the corrected deliverable.
Intellectual property
8.1 Upon full payment of all fees due for an engagement, we assign to you all intellectual property rights in the deliverables created specifically for you under the relevant SOW, other than pre-existing materials and open-source components described below.
8.2 We and our licensors retain all rights in tools, frameworks, libraries, methodologies, and know-how that existed before, or were developed independently of, the engagement ("pre-existing materials"). To the extent pre-existing materials are incorporated into a deliverable, we grant you a non-exclusive, perpetual, worldwide licence to use them as part of that deliverable.
8.3 Deliverables may incorporate open-source software components, which remain governed by their own licences. We will identify material open-source components used in a deliverable on request.
8.4 We may reference your name and a general description of the engagement in our portfolio and marketing materials, unless you object in writing.
AI-assisted development
We use AI-assisted development tools to support design, coding, testing, and documentation. All AI-assisted output is reviewed by our engineers before delivery, and we remain responsible for the quality of deliverables regardless of the tools used to produce them. We do not submit your confidential code or project data to train third-party AI models without your prior written consent.
Confidentiality
Each party agrees to keep the other's confidential information, including project materials, source code, and business and technical information, confidential, and to use it only to perform its obligations under the Agreement. This obligation survives termination of the Agreement and does not apply to information that is or becomes public other than through breach, was already known to the receiving party, or is required to be disclosed by law.
Warranty
We warrant that the Services will be performed with reasonable skill and care. For 30 days following delivery of a deliverable, we will correct, at no additional charge, any material defect that causes the deliverable not to conform to the agreed specification, provided the defect is not caused by your modification, misuse, or use with incompatible systems. Except as expressly stated in this Section, the Services and deliverables are provided without warranties of any kind, to the extent permitted by applicable law. Nothing in this Section affects statutory warranties that cannot be excluded under the law applicable to you as a consumer.
Limitation of liability
To the maximum extent permitted by applicable law, neither party is liable for indirect, incidental, special, or consequential damages, including loss of profits, revenue, business, or data, even if such loss was foreseeable. Our total aggregate liability arising out of or in connection with an engagement will not exceed the total fees you paid us for that engagement in the 12 months preceding the event giving rise to the claim.
Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable law, including liability for death or personal injury caused by negligence, for fraud, or under mandatory consumer protection law.
Non-solicitation
During an engagement and for 12 months after its conclusion, you agree not to directly solicit for hire or engage, as an employee or independent contractor, any of our personnel who were involved in delivering the Services to you, without our prior written consent.
Termination
Either party may terminate an engagement for material breach that remains uncured 14 days after written notice, or as otherwise provided in the SOW. We may also suspend or terminate access to the website or the Services where you breach these Terms or our Acceptable Use Policy. On termination, you pay for work performed and expenses properly incurred up to the effective date of termination; see also our Refund Policy.
Force majeure
Neither party is liable for delay or failure to perform caused by events beyond its reasonable control, including natural disasters, war, civil unrest, government action, internet or power outages, or failures of third-party infrastructure providers, provided the affected party gives prompt notice and uses reasonable efforts to mitigate the impact.
Governing law and disputes
These Terms are governed by the laws of the Kyrgyz Republic. The parties will first attempt to resolve any dispute amicably through good-faith negotiation, contacting legal@vaizen.dev. If a dispute cannot be resolved amicably within 30 days, it will be referred to the competent courts of Bishkek, Kyrgyz Republic.
If you are a consumer, this choice of law and forum does not deprive you of protection afforded by mandatory provisions of the law of your country of habitual residence, including any right to bring proceedings before the courts of that country.
Consumers
Where you engage us as an individual acting outside a trade, business, craft, or profession, mandatory consumer protection law applicable to you takes precedence over any conflicting provision of these Terms. See also our Refund Policy for statutory rights that may apply to you.
Changes to these terms
We may update these Terms by posting a new version on our website with a new "Last updated" date. Material changes affecting an active engagement will be communicated to you directly. Continued use of the website after changes take effect constitutes acceptance of the updated Terms; changes to an active engagement still require agreement under Section 4.
