Legal & Privacy

These Terms of Service (the “Terms”) form a binding agreement between you and Vorontsov Vasily, operating the Quanta service (“Quanta,” “we,” “us,” or “our”). They govern the Quanta websites, studio, AI agents, generated workspaces, previews, backend runtimes, integrations, downloads, APIs, and related services (collectively, the “Services”).

By creating an account, clicking an acceptance control, or using the Services, you accept these Terms, the Acceptable Use Policy, and the processing described in the Privacy Policy. If you use the Services for an organization, you represent that you have authority to bind it; “you” then includes that organization.

You must be at least 18 years old and legally capable of entering a contract. The Services are not directed to children under 13, and Quanta does not knowingly offer accounts to children.

• Provide accurate account information and keep it current.
• Protect passwords, OAuth access, API credentials, recovery methods, and devices used with your account.
• Do not share an individual account or allow unauthorized access.
• Notify us promptly at team@quanta-ai.dev if you suspect compromise.
• You are responsible for activity performed through your account unless caused by our breach of an applicable duty.

Quanta uses probabilistic AI models and automated tools to clarify requests, create plans, generate or modify code, prepare designs and backend schemas, execute bounded development commands, and produce previews or downloadable artifacts. Outputs may change between runs even when inputs are similar.

• Outputs may be inaccurate, incomplete, insecure, offensive, unavailable, or unsuitable for your purpose.
• Quanta may pause and ask questions, reject requests, enforce resource limits, or stop automated actions for safety or reliability.
• You must review, test, scan, and validate generated code and content before relying on or deploying it.
• Do not use the Services as the sole basis for decisions with legal or similarly significant effects, or as a substitute for qualified professional advice.
• Preview and generated-backend environments are development facilities, not guaranteed production hosting.

Inputs include prompts, files, images, Figma data, repository content, instructions, feedback, and other material you provide. Outputs include code, text, plans, schemas, designs, and other material generated for you.

As between you and Quanta, you retain your rights in Inputs. Subject to applicable law and these Terms, Quanta assigns to you any rights it may have in Outputs upon generation. Because machine-generated material may not qualify for intellectual-property protection and similar outputs can be generated for others, we do not promise that any Output is unique, protectable, or free from third-party claims.

You grant Quanta a worldwide, non-exclusive, royalty-free license to host, reproduce, transform, transmit, and otherwise process Inputs and Outputs only as reasonably needed to operate, secure, support, and improve the Services; comply with law; enforce these Terms; and follow your instructions. We do not obtain ownership of your application merely because it was built with Quanta.

Quanta and its licensors retain all rights in the Services, models, orchestration, prompts, interfaces, documentation, trademarks, and platform technology, excluding your Inputs and assigned rights in Outputs. If you provide product feedback, you grant us a perpetual, worldwide, irrevocable, royalty-free right to use it without restriction or compensation, provided we do not publicly identify you without permission.

You must comply with the Acceptable Use Policy. You may not bypass safeguards, probe other users’ data, introduce malware, infringe rights, generate unlawful material, or use Quanta for prohibited high-impact decisions.

Integrations such as Google, GitHub, Figma, AI-model providers, image providers, email providers, and app stores are governed by their own terms. You authorize Quanta to access and act on connected services within the permissions you grant. We are not responsible for third-party services, their availability, or changes they make.

Some Services may be free, preview, invitation-only, usage-limited, or paid. The price, billing period, included usage, renewal terms, and material restrictions presented at purchase become part of these Terms. Unless mandatory law says otherwise, fees are payable in the stated currency and exclude applicable taxes.

• We will not charge an automatically renewing fee unless renewal terms and required consent are presented before purchase.
• You may cancel a renewal before the next billing date using the available account or support process.
• Usage already consumed, custom work, and digital services already fully performed may be non-refundable to the extent permitted by law.
• Statutory cancellation, refund, and consumer rights remain unaffected.

We may improve or modify the Services and establish reasonable technical, safety, or usage limits. Material adverse changes to paid Services will be communicated in advance when reasonably practicable and as required by law. Beta or experimental features may be changed or withdrawn and may not meet the reliability or support level of generally available features.

We may temporarily suspend access to protect users or the Services, comply with law, address security incidents, prevent abuse, or perform maintenance. We do not promise uninterrupted operation.

You may stop using Quanta at any time and may request account deletion. We may restrict, suspend, or terminate access if you materially or repeatedly violate these Terms, create risk or legal exposure, fail to pay applicable fees, or if required by law. Where appropriate, we will give notice and a reasonable opportunity to cure or export data.

Upon termination, your license to use the Services ends. Provisions that by their nature should survive—including ownership, accrued payment duties, disclaimers, liability limits, dispute provisions, and record-retention rights—continue to apply.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICES AND OUTPUTS ARE PROVIDED “AS IS” AND “AS AVAILABLE.” QUANTA DISCLAIMS IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

We do not warrant that Outputs are accurate, unique, secure, lawful, production-ready, or compatible with every platform. These disclaimers do not limit an express warranty we separately provide or any warranty that cannot be excluded under applicable consumer law.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, QUANTA WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, BUSINESS, DATA, GOODWILL, OR USE, EVEN IF ADVISED OF THE POSSIBILITY.

OUR AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICES WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID QUANTA FOR THE SERVICES GIVING RISE TO THE CLAIM DURING THE 12 MONTHS BEFORE THE EVENT OR (B) USD 100. This cap does not apply where prohibited by law, or to liability that cannot lawfully be limited, including fraud or willful misconduct and, where applicable, death or personal injury caused by negligence.

If you use Quanta on behalf of a business and to the extent permitted by law, you will defend and indemnify Quanta from third-party claims arising from your Inputs, your deployed application, your unlawful or unauthorized use, or your material breach of these Terms. This does not apply to consumer use where such an obligation is prohibited, or to claims caused by Quanta’s own breach.

Before filing a claim, contact team@quanta-ai.dev with a description and requested resolution; the parties will attempt in good faith to resolve it for 30 days. This does not prevent either party from seeking urgent injunctive relief or using a regulator or small-claims process.

Except where mandatory law provides otherwise, these Terms are governed by the laws of the Russian Federation, without regard to conflict-of-laws rules, and disputes are submitted to the competent courts at the operator’s place of residence. Consumers retain the protection and venue rights of mandatory law in their place of residence, including applicable U.S. state and Russian consumer-protection law.

These Terms and incorporated policies are the entire agreement about the Services. If a provision is unenforceable, it will be enforced to the maximum lawful extent and the rest remains effective. Failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them as part of a reorganization or transfer of the Services, subject to applicable notice and consumer rights.

We may update these Terms for legal, security, technical, or product reasons. We will post the revised version and change the effective date. For material changes, we will provide reasonable advance notice and, when law requires, request renewed acceptance. Continued use after the effective date constitutes acceptance only where legally valid.

This Privacy Policy explains how Quanta handles personal information when you visit, register, connect integrations, use the AI builder, contact us, or otherwise use the Services.

Quanta generally acts as the controller/operator of account, service, security, and billing data. When a business customer submits personal information on behalf of others in project content, Quanta may act as its service provider/processor under the customer’s instructions. The customer remains responsible for notices, permissions, and a lawful basis for that data.

We collect information from you, automatically from your use, from connected services you authorize, and from service providers supporting Quanta.

Sources include account forms; your prompts and uploads; Google, GitHub, and Figma when connected; your device and network; email and infrastructure providers; and information you make available when requesting support.

• Provide the contract: create accounts, execute build requests, maintain conversations and projects, provide previews, downloads, integrations, support, and billing.
• Operate safely: authenticate, prevent fraud and abuse, isolate workspaces, investigate incidents, enforce policies, and protect rights and infrastructure.
• Improve the service: debug failures, evaluate reliability, understand feature performance, and improve workflows using minimized or de-identified data where reasonably possible.
• Communicate: send verification, security, transactional, support, and legally required notices. Marketing will use a separate opt-in where required.
• Comply: maintain records, respond to lawful requests, establish or defend claims, and satisfy accounting, tax, sanctions, and regulatory duties.

Depending on jurisdiction, our legal bases include performance of a contract, steps requested before a contract, compliance with law, legitimate interests balanced against your rights, protection of vital interests, and consent where required. You may withdraw consent prospectively, but withdrawal does not affect prior lawful processing or processing supported by another legal basis.

To generate an application, relevant prompts, conversation context, files, code, tool results, and instructions may be transmitted to configured AI-model providers or gateways. Depending on deployment configuration, these may include OpenAI or a model-routing provider and its selected model hosts. Providers process this information to return model outputs and operate or secure their services under their applicable contracts.

• Quanta does not use AI output to make solely automated decisions producing legal or similarly significant effects about you.
• Quanta’s project memory and agent transcripts retain context so later runs can continue your project.
• We do not authorize providers to use your private project content for targeted advertising.
• Whether a provider uses submitted content for model training depends on the provider, endpoint, and contract selected for the production deployment. Before launch, Quanta will configure providers and contractual controls consistent with this Policy and publish material changes.

We may disclose the minimum necessary information to:

• Infrastructure and operations providers for hosting, databases, storage, email, security, support, and error diagnostics.
• AI and content providers to process prompts and return model or media-search results.
• Connected services such as Google, GitHub, and Figma at your direction.
• Professional advisers and transaction parties under confidentiality in financing, reorganization, acquisition, or asset transfer.
• Authorities and affected parties when reasonably necessary to comply with law, protect safety or rights, prevent fraud, or respond to valid legal process.
• Other people if you share or publish a project or expressly direct us to disclose it.

We retain each category only as long as reasonably necessary for the disclosed purpose, considering account and project status, user instructions, security needs, limitation periods, backup cycles, and legal obligations. The table above states current criteria and target periods.

Deletion removes data from active systems or irreversibly de-identifies it. Residual copies may remain temporarily in encrypted or access-restricted backups until rotation. We may retain limited records to complete deletion, prevent fraud, enforce agreements, comply with law, or establish legal claims. Content already exported to GitHub, Figma, your device, or another third party must be deleted there separately.

We use administrative, technical, and organizational safeguards designed for the nature of the data, including access controls, credential hashing, authenticated internal-service boundaries, workspace isolation, restricted execution, logging, backups, and incident response. No system is completely secure, and we cannot guarantee absolute security.

Use a unique password, protect connected accounts, do not place secrets in prompts or source files, and report suspected compromise promptly.

Subject to applicable law and verification, you may request:

• access to or a copy of personal information;
• correction of inaccurate information;
• deletion, blocking, or restriction of processing;
• information about sources, purposes, recipients, and processing;
• withdrawal of consent or objection to certain processing;
• data portability where applicable;
• opt-out of sale, targeted advertising, or qualifying profiling if such processing is introduced; and
• appeal of a denied request where state law provides that right.

Send requests to team@quanta-ai.dev. Specify the account email, request type, jurisdiction, and enough information for us to verify and locate the records. Authorized agents may submit requests where permitted, subject to proof of authority and identity. We will not discriminate against you for exercising a privacy right.

Residents of California and other U.S. states with comprehensive privacy laws may have rights to know, access, correct, delete, obtain a portable copy, and opt out of sale, targeted advertising, or certain profiling, subject to statutory scope and exceptions.

For California’s required category disclosure, during the preceding 12 months Quanta may have collected identifiers; customer-record information; commercial information; internet or electronic-network activity; geolocation at the approximate IP-derived level; audio/visual information voluntarily uploaded; professional information provided by users; inferences from onboarding or project activity; and sensitive information such as account credentials and message contents. We use and disclose these categories for the business purposes described above. We do not use sensitive personal information to infer characteristics or beyond permitted service and security purposes.

California’s “Shine the Light” law permits residents to request information about disclosure for third parties’ direct marketing; Quanta does not currently make such disclosures. Browser “Do Not Track” signals lack a uniform standard. If Quanta introduces processing covered by Global Privacy Control, it will honor the signal as required.

For users in the Russian Federation, Quanta processes personal data in accordance with applicable requirements of Federal Law No. 152-FZ, including the principles of purpose limitation, data minimization, accuracy, security, and storage no longer than required for processing purposes.

• The categories, subjects, purposes, actions, methods, and retention criteria are described in this Policy and the data table.
• Processing actions may include collection, recording, systematization, accumulation, storage, clarification, extraction, use, provision/access, depersonalization, blocking, deletion, and destruction, using automated and mixed methods.
• Where consent is the legal basis, consent must be specific and separately obtained from acceptance of contractual documents as required by Russian law.
• Russian data subjects may request access, clarification, blocking, or destruction of incomplete, outdated, inaccurate, unlawfully obtained, or unnecessary data and may complain to Roskomnadzor or a court.
• Primary collection and storage of Russian citizens’ personal data must use databases located in Russia where required. Any subsequent cross-border transfer will occur only after required assessments and notifications and subject to Article 12 of Federal Law No. 152-FZ.

Quanta and its providers may process data in countries other than yours. Those countries may have different laws. Where required, we use contractual and organizational safeguards, conduct transfer assessments, provide notices to regulators, and localize data. Cross-border processing will not override mandatory Russian localization or transfer-notification requirements.

Quanta is intended for adults and does not knowingly collect personal information from children under 13 or permit them to create accounts. Users under 18 may not use the Services. If you believe a child provided personal information, contact us so we can investigate and delete it as required.

Quanta currently uses strictly necessary authentication and security cookies. It does not currently use advertising or cross-site tracking cookies. Before introducing non-essential analytics, personalization, or advertising technologies, we will update the Cookie Notice and deploy consent and opt-out controls where required.

We may update this Policy to reflect product, provider, or legal changes. We will post the revised version and effective date and provide additional notice or seek consent for material changes where required.

Contact: team@quanta-ai.dev. You may also complain to your local privacy regulator or seek judicial relief. Russian residents may contact Roskomnadzor; California residents may consult the California Privacy Protection Agency or Attorney General.

This Acceptable Use Policy applies to every prompt, upload, integration, generated application, preview, automated tool, API call, and other use of Quanta. You are responsible for your users and for how you deploy or distribute Outputs.

• Do not violate law, sanctions, court orders, contractual duties, or third-party rights.
• Do not facilitate violence, terrorism, human exploitation, trafficking, child sexual abuse material, non-consensual intimate material, stalking, harassment, or credible threats.
• Do not impersonate others deceptively, operate scams, manipulate users, or create fraudulent documents, evidence, credentials, or endorsements.
• Do not generate or distribute content that unlawfully discriminates or denies protected rights or opportunities.
• Do not use Quanta to identify, locate, profile, or infer sensitive traits about a person without lawful authority and appropriate notice.

• No malware, ransomware, credential theft, phishing, botnets, destructive payloads, covert persistence, unauthorized surveillance, or evasion designed for abuse.
• No unauthorized access, vulnerability exploitation, denial of service, scraping that violates access controls, or attempts to retrieve another user’s data.
• No bypassing quotas, safety controls, authentication, workspace boundaries, rate limits, or model/provider restrictions.
• Security research is allowed only against systems you own or are explicitly authorized to test, within applicable law and scope.
• Do not upload secrets, private keys, production credentials, or malware samples unless an expressly authorized feature and containment procedure supports them.

• Only submit personal data, source code, designs, images, and confidential information you are authorized to process.
• Obtain required notices, consents, licenses, and permissions before using another person’s data or work.
• Do not deliberately request outputs that copy a living creator, brand, product, or proprietary codebase in an infringing or deceptive manner.
• Do not expose personal information, doxx individuals, or build tools primarily intended for covert tracking or unlawful facial/biometric identification.

Without Quanta’s prior written approval and a qualified human review process, do not use Quanta or its Outputs to make or materially support decisions about:

• employment, worker evaluation, education admissions, housing, lending, insurance, or access to essential services;
• medical diagnosis, treatment, emergency response, or patient triage;
• legal rights, law enforcement, criminal risk, migration, or eligibility for public benefits;
• financial trading, individualized investment advice, credit scoring, or gambling; or
• critical infrastructure, weapons, transport safety, or other systems where failure could cause serious harm.

Approval does not replace compliance, professional licensing, validation, human oversight, notices, appeal rights, or sector-specific safeguards.

• Do not claim that an Output was reviewed, certified, endorsed, secure, or legally compliant when it was not.
• Clearly disclose synthetic or automated content where law, platform rules, or context requires it.
• Do not deploy manipulative interfaces, dark patterns, fake reviews, undisclosed bots, deceptive deepfakes, or systems designed to confuse users about who or what they are interacting with.

We may reject or stop requests, remove content, restrict tools, preserve evidence, suspend accounts, or notify affected parties or authorities when reasonably necessary to enforce this Policy, protect safety, or comply with law. We consider context, intent, severity, history, and available remediation.

Report suspected abuse or seek authorization guidance at team@quanta-ai.dev. Include relevant project, account, URL, and evidence without sending unnecessary personal or harmful content.

Quanta currently uses cookies and similar browser storage that are strictly necessary to authenticate users, protect sign-in flows, maintain security, route OAuth callbacks, and remember essential session state. These technologies are required for requested account functionality and cannot be disabled through a consent banner without breaking the service.

Exact cookie names may vary by environment, HTTPS configuration, authentication provider, and library version. Quanta does not rely on cookie names as a substitute for the category and purpose disclosures above.

If Quanta adds optional analytics, personalization, experimentation, marketing, or advertising technologies, we will first:

• update this Notice with provider, purpose, data, duration, and recipient details;
• prevent non-essential technologies from loading before consent where opt-in is required;
• offer equally accessible “Accept,” “Reject,” and granular settings controls;
• record and honor withdrawal and region-specific opt-out signals, including Global Privacy Control where applicable;
• avoid conditioning core service access on unnecessary tracking where prohibited; and
• obtain separate consent for any use requiring it under Russian law.

You can sign out and clear cookies using browser controls. Blocking all cookies may prevent registration, sign-in, OAuth connections, security validation, and Studio functionality. When optional cookies are introduced, Quanta will provide a persistent privacy-settings entry point for changing your selection.

For information about related personal-data processing, see the Privacy Policy.

We may update this Notice as the technology stack changes. Material changes will be highlighted and, where required, renewed consent will be requested before new optional cookies are activated. Questions may be sent to team@quanta-ai.dev.
