1. Acceptance of Terms
These Terms of Service govern your access to and use of Perture, including the website, application, account system, subscriptions, Brand Pages, uploads, assets, design-system tools, Logs, Brand Quality Index, collaboration, plugins, API, MCP, documentation, and related services. By creating an account, accessing Perture, subscribing to a paid plan, generating credentials, connecting integrations, or using the Service, you agree to these Terms and to the Privacy Policy. If you use Perture on behalf of a company, client, brand, agency, employer, or other entity, you represent that you have authority to bind that entity and to provide or manage the relevant content. If you do not agree to these Terms, do not use Perture.
2. The Service
Perture is a Brand Page and design-system platform for AI-assisted interface work. The Service lets users organize brand references, assets, rules, components, Interface System data, and context; connect authorized plugins and agents; review brand quality and activity Logs; and, where the plan permits, collaborate through a Team Workspace, share or transfer Brand Pages, and make scoped edits through Pro MCP tools. Some import, integration, or agent capabilities may be beta or depend on external providers. Perture is not a design agency, law firm, compliance service, intellectual-property clearance service, advertising approval service, or publication guarantee. You remain responsible for final decisions about publication, legality, licensing, compliance, brand suitability, accuracy, and use of any material, output, or third-party result.
3. Eligibility and Account
You must be legally able to enter into these Terms under applicable United States law and the law of your state of residence. Perture is not intended for children under 13. You may need to create an account with your name, email address, and password to use the Service. You are responsible for providing accurate account information, keeping your account current, and protecting your password, devices, sessions, API keys, tokens, secrets, and integrations. Activity under your account or credentials may be treated as authorized by you unless you promptly notify Perture of unauthorized access and provide reasonable evidence that the activity was not caused by your failure to secure your account or credentials.
4. Plans, Billing, and Payment
Perture offers monthly Solo at US$25 and Pro at US$249. Solo includes one member, one Brand Page with 100 MB of storage, official plugins with plugin-scoped MCP access for brand context and checks, Logs, Brand Quality Index, and standard support. Pro includes those common features plus up to ten members, up to ten Brand Pages with 500 MB per Brand Page, Team Workspace, Brand Page sharing and transfer, scoped Pro MCP editing of Brand Page records and agent settings, priority support, and one initial implementation as described at checkout. Solo does not include new additional Brand Pages; previously purchased Solo add-ons remain subject to their existing subscription terms until removed or migrated. Neither plan includes a free trial. Applicable taxes and any amount due are presented in checkout or before an upgrade is confirmed.
Solo billing starts when you complete Checkout. For a new Pro subscription, Checkout saves a payment method without an immediate charge; the Pro subscription and recurring billing start when the included implementation is marked complete. An existing Solo subscriber can instead review and confirm an immediate Solo-to-Pro upgrade. The amount due, including applicable proration, is shown before confirmation; when the upgrade succeeds, the Pro subscription replaces Solo without waiting for the initial implementation. Perture uses Stripe for checkout, recurring billing, invoices, payment processing, payment-method management, and billing portal functionality. Perture may store customer, subscription, plan, billing-period, status, implementation, workspace, and entitlement identifiers, but does not intend to store full payment card numbers or card security codes.
By subscribing to a paid plan, you authorize recurring monthly charges until you cancel future renewals. Once a billing period has been paid, cancellation does not undo that purchase or reverse its charge. Unless otherwise stated at checkout or in the billing portal, cancellation stops the next renewal and paid access continues until the end of the current paid billing period. You can cancel future renewals through the billing portal or another method made available by Perture. Deleting your account may not automatically cancel your subscription; to avoid future charges, cancel your subscription before deleting your account. If payment fails, Perture or Stripe may retry payment, request an updated payment method, suspend paid features, reduce access, limit entitlements, or cancel the subscription. You are responsible for all applicable taxes, duties, levies, and governmental charges other than taxes based on Perture's income.
Payments for completed billing periods are final. Perture does not provide refunds, partial refunds, or credits for unused time after payment, except where applicable law requires otherwise. Cancelling a subscription prevents future renewals; it does not refund or cancel a period already paid for.
5. User Content and Ownership
You retain ownership of the content you upload, create, store, organize, or make available through Perture, including brand references, logos, fonts, images, files, documents, rules, components, examples, feedback, outputs, assets, and related Brand Page materials. You grant Perture a worldwide, non-exclusive, limited, royalty-free license to host, store, copy, process, display, transmit, deliver, analyze, validate, and make your User Content available as necessary to provide, secure, maintain, and improve the Service and to operate features you authorize, including collaboration, plugins, API, MCP, Logs, Brand Quality Index, previews, controlled delivery, support, and technical operations. This license is for operating Perture and does not transfer ownership of your User Content to Perture.
6. Your Responsibility for Rights
You represent and warrant that you have all rights, licenses, consents, and permissions necessary to upload, store, process, use, share, and authorize access to your User Content through Perture. This includes rights related to trademarks, logos, fonts, images, photographs, illustrations, documents, layouts, examples, outputs, client materials, and other assets. You are responsible for font licenses, image licenses, copyright permissions, trademark rights, publicity rights, confidentiality obligations, client agreements, platform rules, and any restrictions that apply to the materials you provide. Perture does not verify that you own or have licensed your User Content and is not responsible for unauthorized uploads or use.
7. Perture Intellectual Property and Proprietary Rights
Perture and its licensors own the Service, including the software, interface, design, code, APIs, MCP, documentation, workflows, systems, methods, structures, logic, know-how, technical processes, validation approaches, operational models, trade secrets, trademarks, branding, and other proprietary materials. These Terms do not grant you ownership of Perture or any Perture intellectual property. You receive only a limited, revocable, non-transferable right to use the Service according to these Terms and your plan. You may not copy, modify, reverse engineer, decompile, disassemble, scrape, extract, replicate, bypass, exploit, or use Perture to build a competing product or discover non-public methods, except where such restriction is prohibited by applicable law.
8. Files, Assets, and External Delivery
Perture may allow you to upload files and assets for use inside the Service and in authorized workflows. Perture may store those files using private storage, controlled infrastructure, or other technical systems appropriate for the Service. To deliver assets, previews, downloads, integrations, API responses, or external workflows, Perture may use controlled links, temporary links, CDN delivery, repository-based delivery, or equivalent technical mechanisms. Links and externally delivered assets may be accessible to people or systems that receive them, subject to their technical configuration and availability. You are responsible for treating non-public asset links as confidential and for authorizing only workflows that are appropriate for the relevant content.
9. Collaboration and Project Sharing
Pro may allow you to share Brand Pages with other users by email and available permissions, collaborate in a Team Workspace, and transfer a Brand Page to another account. Solo is limited to one member and does not include Brand Page sharing or transfer. Collaborators may be able to view, edit, or administer content according to their permissions. You are responsible for inviting only authorized collaborators, reviewing access, removing collaborators when needed, and verifying the recipient before transferring ownership. A transfer may give the new owner substantial control over the Brand Page.
10. Integrations, API, MCP, and External AI Systems
Perture may provide official plugins, API access, MCP access, credentials, OAuth-style authorization, scopes, and related tools for authorized systems. Both plans include only the MCP access needed by official plugins for brand context and checks; this is not a general permission to edit Brand Pages or Perture settings. Pro may also provide separately authorized, scoped MCP tools for editing Brand Page records and agent settings. You are responsible for securing all credentials, API keys, tokens, secrets, environments, repositories, and connected systems. You may not publish credentials, expose them in insecure clients, share them with unauthorized parties, bypass scopes, evade limits, or use credentials to access content or systems you are not authorized to access.
Perture may apply quotas, rate limits, scopes, access limits, audits, credential rotation, revocation, suspension, endpoint blocking, or account restrictions for security, stability, billing, abuse prevention, legal compliance, or enforcement. External AI platforms, hosts, agents, and connectors are separate third parties when you connect or authorize them. Sending brand context, logs, requests, or proposed fixes to an agent may consume that provider's tokens or credits and may incur charges under your agreement with that provider. You are responsible for what you connect, send, request, generate, accept, publish, or use through those third parties. Perture does not guarantee that AI or third-party outputs are accurate, original, lawful, non-infringing, brand-compliant, safe, or ready for publication.
11. Brand Quality, Logs, and Agent Workflows
Brand Quality Index, Logs, automated reviews, and suggested corrections are informational tools. They may be incomplete, delayed, or inaccurate and do not certify legal compliance, accessibility, ownership, security, or fitness for publication. You must review any issue, recommendation, or agent-generated change before relying on it or deploying it.
When you authorize an agent workflow, Perture may send the selected Brand Page context, relevant logs, issues, and proposed solutions to that agent or connected provider to perform the requested task. Review the destination, scope, and potential third-party token usage before continuing. Do not submit secrets or regulated information unless the workflow and provider are appropriate for that data.
12. Acceptable Use
You may not use Perture to upload, store, transmit, process, validate, distribute, or enable illegal, fraudulent, infringing, malicious, abusive, defamatory, unlawfully discriminatory, exploitative, or harmful content. You may not use Perture to violate copyright, trademark, font licenses, image licenses, publicity rights, privacy rights, confidentiality obligations, client agreements, platform rules, or other third-party rights. You may not upload malware, spyware, exploits, stolen secrets, unauthorized credentials, or malicious code; perform abusive scraping, credential stuffing, phishing, spam, unauthorized testing, load attacks, reverse engineering, vulnerability exploitation, entitlement bypass, billing bypass, rate-limit evasion, unauthorized resale, or interference with Perture's infrastructure; or use Perture to collect personal information without a lawful basis and proper notice.
You may not use Perture in a manner that harms Perture, users, service providers, third parties, infrastructure, availability, security, or reputation. Perture may investigate, restrict, suspend, or terminate use that appears to violate these Terms, create risk, or expose Perture or others to harm.
13. Third-Party Services
Perture uses or may integrate with third-party providers for authentication, database, storage, billing, hosting, infrastructure, fonts, CDN, asset delivery, API, MCP, and integrations you authorize. These providers may include Amazon Web Services, Supabase, Stripe, Google Fonts, CDN or repository providers when required for authorized workflows, and external AI platforms or connectors when you authorize them. Third-party services are governed by their own terms, policies, security practices, availability, pricing, and retention rules. Perture is not responsible for failures, outages, changes, removals, fees, outputs, decisions, retention, or data handling by third-party services.
14. Privacy
Your use of Perture is governed by the Privacy Policy. By using the Service, you acknowledge that Perture may collect, use, disclose, and retain information as described in that Policy. Connecting third-party agents or sharing Brand Page content may create independent obligations for you, including notice, consent, contracts, security, data rights, and legal basis.
15. Availability, Changes, and Beta Features
Perture may change, add, remove, limit, suspend, discontinue, rename, reprice, or modify features, integrations, API, MCP, plans, entitlements, workflows, and documentation at any time. Some features may be beta, experimental, incomplete, or subject to change. Beta features may contain errors, lose compatibility, change without notice, be rate-limited, produce unexpected results, or be discontinued. Perture does not guarantee uninterrupted availability, error-free operation, permanent compatibility with external systems, preservation of every integration, commercial performance, conversion improvement, revenue growth, creative quality, or specific business outcomes.
16. Account Deletion, Suspension, and Termination
You may stop using Perture at any time. You may delete your account through the available account-deletion flow, which may require password confirmation and an express confirmation step. Account deletion may be irreversible and may remove active account content according to Perture's deletion process. Deleting your account does not necessarily cancel your paid subscription; cancel your subscription through the billing portal or another method made available by Perture before deleting your account if you want to avoid future charges.
Perture may suspend or terminate your account, projects, credentials, integrations, API access, MCP access, performance features, or use of the Service if Perture believes you violated these Terms, failed to pay, created a security risk, exposed credentials, infringed rights, misused tracking, abused infrastructure, triggered third-party complaints, violated law, or created legal, operational, financial, or reputational risk. After deletion, suspension, or termination, some information may remain in backups, logs, billing records, tax records, security records, fraud-prevention records, legal records, or third-party systems for reasonable or legally required periods.
17. Copyright Complaints and DMCA
If you believe content available through Perture infringes your copyright, send a notice to supportperture@gmail.com. Your notice should include identification of the copyrighted work, identification of the allegedly infringing material, your contact information, a statement that you have a good-faith belief that the disputed use is not authorized, a statement under penalty of perjury that the information in the notice is accurate and that you are authorized to act on behalf of the copyright owner, and your physical or electronic signature. Perture may remove or disable access to allegedly infringing content and may terminate repeat infringers when appropriate.
18. Disclaimers
To the maximum extent permitted by law, Perture is provided "as is" and "as available," without warranties of any kind, whether express, implied, statutory, or otherwise. Perture disclaims warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, availability, security, uninterrupted operation, error-free operation, compatibility, and results. Perture does not provide legal, regulatory, tax, accounting, advertising, intellectual-property, or compliance advice. You should obtain professional review before publishing materials, using fonts or images, relying on outputs, installing performance features, connecting external systems, or making legal or commercial decisions.
Perture does not guarantee that brand references, rules, validations, performance signals, integrations, AI outputs, third-party outputs, or external workflows will be correct, lawful, non-infringing, original, brand-compliant, secure, unbiased, complete, or ready for publication. You are responsible for human review and final approval of any material or output before use.
19. Limitation of Liability
To the maximum extent permitted by law, Perture will not be liable for indirect, incidental, special, consequential, exemplary, punitive, or enhanced damages, including lost profits, lost revenue, lost data, loss of goodwill, business interruption, replacement costs, third-party failures, integration failures, AI output errors, publishing decisions, infringement caused by User Content, unauthorized use of assets, font or image license violations, misuse of performance features, credential compromise, or unauthorized account activity. To the maximum extent permitted by law, Perture's total liability for all claims related to the Service will not exceed the greater of US$100 or the amount you paid to Perture in the 12 months before the event giving rise to the claim. Some jurisdictions do not allow certain limitations, so some limitations may not apply to you.
20. Indemnification
You agree to defend, indemnify, and hold harmless Perture, its affiliates, officers, directors, employees, contractors, service providers, and agents from and against claims, damages, losses, liabilities, costs, and expenses, including reasonable attorneys' fees, arising from or related to your User Content, your use of the Service, your violation of these Terms, your violation of law, your violation of third-party rights, your use of assets without proper rights, your misuse of fonts, images, marks, or client materials, your installation or use of performance features without proper notice or consent, your misuse of API or MCP access, your exposure of credentials, your authorized third-party connections, your publication or use of outputs, or your use of Perture on behalf of another person or entity without proper authority.
21. Changes to Terms
Perture may update these Terms from time to time. If changes are material, Perture may provide notice by email, in-product notice, or another reasonable method. The updated Terms will be effective as of the date stated in the updated version. Your continued use of Perture after the updated Terms become effective means you accept the updated Terms, where permitted by law. If you do not agree to updated Terms, you must stop using Perture and cancel any paid subscription before the next renewal.
22. Governing Law and Disputes
These Terms are governed by the laws of the State of Delaware, United States, and applicable federal law, without regard to conflict-of-law rules. Any dispute will be resolved in the state or federal courts located in Delaware, unless Perture adopts arbitration in a later version of these Terms. The parties agree to attempt to resolve disputes informally by written notice to supportperture@gmail.com for at least 30 days before filing a formal claim, except for urgent matters, intellectual-property protection, security incidents, fraud, payment disputes, or situations where immediate action is legally permitted.
23. General Terms
You may not assign these Terms without Perture's consent, except where assignment is permitted by law. Perture may assign these Terms in connection with a merger, acquisition, financing, reorganization, sale of assets, corporate transaction, or business succession. If any provision is found invalid or unenforceable, the remaining provisions will remain in effect. Perture's failure to enforce a provision is not a waiver. These Terms, together with the Privacy Policy and any incorporated notices, form the entire agreement between you and Perture regarding the Service, unless you have a separate written agreement signed by Perture.
