Terms of Service
Effective Date & Last Revised: August 16, 2026//Version 2.1
Agreement Summary
By creating an account, subscribing, or using Blueprint Nexus (operated by Blueprint Nexus Inc.), you agree to these Terms. If you do not agree, do not use the Service.
Section 20 contains a binding arbitration agreement and a class action waiver that affect how disputes are resolved. You may opt out of arbitration within 30 days.
01.Agreement & Acceptance
These Terms of Service form a binding agreement between you and Blueprint Nexus Inc. ("Blueprint Nexus", "we", or "us") governing your use of the Blueprint Nexus website, web application, iOS application, API, and MCP endpoints (together, the Service). Our Privacy Policy is incorporated by reference. If you have signed a separate written agreement with us, that agreement controls where it conflicts with these Terms.
02.Eligibility
You must be at least 18 years old, or the age of majority in your jurisdiction, to create an account or purchase a subscription. Users aged 13 to 17 may use the Service only under a parent or guardian's account and supervision. The Service is not available to anyone under 13. By using the Service you represent that:
- You have the authority to enter into this agreement.
- If you act on behalf of an organization, you have authority to bind that organization, and "you" refers to that organization.
- Your registration information is accurate and kept current.
- You are not barred from using the Service under applicable law.
03.Accounts & Security
You are responsible for safeguarding your credentials, API keys, and session tokens, and for all activity under your account — including agent actions, compute consumption, and charges. Notify us immediately at security@blueprintsociety.com if you suspect unauthorized access. We may require you to reset credentials or may suspend access to protect the Service.
04.The Service, Changes & Beta Features
We continuously develop the Service and may add, modify, or discontinue features. We will give reasonable advance notice before discontinuing a material feature you actively use or making a change that substantially reduces core functionality of a paid plan.
Features labeled beta, preview, alpha, or experimental are provided for evaluation, may be changed or withdrawn at any time, may be unstable, and are excluded from any availability commitment. We do not guarantee uninterrupted availability and provide no service level commitment except under a signed enterprise agreement.
05.Plans, Billing & Renewal
Blueprint Nexus offers free and paid plans. Web payments are processed by Stripe; iOS purchases are processed by Apple and managed through RevenueCat.
- Auto-renewal: paid subscriptions are billed in advance and renew automatically at the then-current rate each period until cancelled. You authorize us (or the applicable app store) to charge your payment method on each renewal.
- Cancellation: cancel any time from your account settings — or, for iOS purchases, from your Apple ID subscription settings. Cancellation takes effect at the end of the current billing period; you keep access until then.
- Price changes:we may change prices with at least 30 days' notice before the change applies to your next renewal. Your remedy if you disagree is to cancel before that renewal.
- Taxes: stated prices exclude taxes. You are responsible for applicable sales, use, VAT, or GST, which we collect where required.
- Trials: free trials convert to paid subscriptions at the end of the trial unless cancelled beforehand. We limit trials to one per user or organization.
- Failed payments: we may retry, and may downgrade or suspend paid features if payment remains outstanding.
06.Usage Limits & AI Credits
Plans include usage allowances for AI tokens, agent runs, sandbox compute, and research calls. Allowances are consumed as you use them, do not carry over between periods unless stated, and have no cash value. We may apply rate limits and fair-use limits to protect platform stability, and may require an upgrade for sustained usage that materially exceeds your plan. Consumed credits are not refundable, including where AI output does not meet your expectations.
07.Refunds
Except as stated here or required by law, fees are non-refundable and we do not provide refunds or credits for partial periods, unused allowances, or downgrades.
- App Store purchases: refunds for purchases made through Apple are handled by Apple under its policies; we cannot issue them.
- Statutory rights: consumers in the EU, UK, and other jurisdictions with mandatory withdrawal or refund rights retain those rights in full.
- Enterprise: refund terms in a signed order form or SLA control over this section.
08.Additional Terms for Apple App Store Users
If you obtained our iOS application from the Apple App Store, the following applies and prevails over any conflicting provision:
- This agreement is between you and Blueprint Nexus Inc. only, not with Apple. Apple is not responsible for the application or its content.
- Apple has no obligation to provide maintenance or support for the application. Support requests go to hello@nexus.dev.
- If the application fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price; to the maximum extent permitted by law, Apple has no other warranty obligation.
- Apple is not responsible for addressing claims relating to the application, including product liability, legal or regulatory non-compliance, and consumer protection claims, or for third-party claims that the application infringes intellectual property rights.
- You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and are not on any U.S. Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
09.Your Content & Ownership
You own your content
You retain all ownership of the blueprints, architecture nodes, code, documents, notes, literature indices, and other content you create or upload in your Blueprint Knowledge Network (BKN). As between you and us, you also own the outputs generated for you by the Service's AI features, to the extent such outputs are capable of ownership.
To operate the Service, you grant us a worldwide, non-exclusive, royalty-free license to host, store, reproduce, transmit, display, and modify your content — and to transmit it to the sub-processors listed in our Privacy Policy — solely to provide, secure, and support the Service for you and the collaborators you authorize. This license ends when you delete the content or your account, subject to the retention periods in the Privacy Policy. We do not use your content to train AI models.
You are responsible for your content and represent that you have the rights necessary to submit it and that it does not infringe third-party rights or violate law. AI outputs may be similar or identical to output generated for other users; we make no exclusivity claim about them.
10.Our Intellectual Property & Feedback
We retain all right, title, and interest in the Service — including the platform software, agent runtime, relational graph schemas, visual design, and brand assets. These Terms grant you a limited, revocable, non-exclusive, non-transferable right to use the Service in accordance with them; no other license is granted by implication.
If you send us feedback, suggestions, or feature ideas, you grant us a perpetual, irrevocable, royalty-free license to use them without restriction or obligation to you.
11.AI Agents & Automated Execution
The Service runs autonomous and semi-autonomous agents under governance levels you select (L0–L3). Higher levels take more actions with less confirmation.
- You direct the agents. You are responsible for the governance level you choose, the permissions and integrations you grant, and everything your agents do under your account.
- Human review is required. AI-generated code, architecture, and recommendations must be reviewed, tested, and validated by a qualified human before use in production or in any consequential decision.
- Outputs may be wrong. Models can produce inaccurate, incomplete, insecure, or infringing output. Output is not legal, financial, medical, or professional advice.
- Provider terms apply. Your use of AI features must comply with the usage policies of the underlying model providers. If you supply your own provider API keys, you are responsible for your agreement with that provider and for all charges it bills you.
12.Code Execution & Sandbox Environments
The Service can execute code in isolated sandbox VMs. You are responsible for all code and commands run under your account, whether written by you or generated by an agent. You must not use sandboxes to mine cryptocurrency, host public services, attack or scan systems you do not own, circumvent resource limits, or store unlawful material. Sandboxes are ephemeral: treat anything not saved into your workspace as lost when the environment is reclaimed. We may terminate a sandbox that threatens platform stability or security.
13.Third-Party Services & Integrations
The Service can connect to third-party services such as version control, calendars, issue trackers, and other applications you authorize. Those services are operated by third parties under their own terms and privacy policies; we do not control them and are not responsible for their availability, accuracy, or the way they handle data you send them. Enabling an integration authorizes the data exchange described at connection time. A third-party service may change or terminate its API, which can break an integration through no fault of ours.
14.Acceptable Use
You agree not to, and not to permit anyone else to:
- Reverse-engineer, decompile, scrape, or attempt to extract the source code or model configuration of the Service, except where that restriction is prohibited by law.
- Generate or distribute malware, conduct denial-of-service attacks, or perform unauthorized penetration testing or network scanning.
- Access another user's workspace or data without authorization, or probe, bypass, or defeat authentication, rate limits, quotas, or usage controls.
- Upload or generate content that infringes intellectual property, violates privacy or data protection law, or is unlawful, harassing, or sexually exploitative of minors.
- Use the Service to build or train a competing AI model or product, or to resell platform access other than as expressly permitted.
- Misrepresent AI-generated output as human-generated where doing so is deceptive or unlawful.
We may investigate suspected violations and take proportionate action, including removing content and suspending accounts.
15.API, MCP Access & API Keys
API and MCP keys are issued to you and must be kept confidential and scoped to the minimum permissions needed. You are responsible for all requests made with your keys. We may change, version, deprecate, or rate-limit API endpoints, and will give reasonable notice of breaking changes where practical. We may revoke a key that is abused, leaked, or used in violation of these Terms.
16.Copyright & DMCA
We respond to notices of alleged copyright infringement and terminate repeat infringers. Send notices to copyright@blueprintsociety.com including: identification of the copyrighted work; identification of the material claimed to be infringing and its location; your contact information; a statement of good-faith belief that the use is not authorized; a statement, under penalty of perjury, that the notice is accurate and you are authorized to act; and your physical or electronic signature. You may submit a counter-notice if your content was removed in error.
17.Suspension & Termination
You may stop using the Service and delete your account at any time from your account settings.
We may suspend or terminate your access if you materially breach these Terms, if your payment is overdue, if your usage threatens the security, integrity, or availability of the Service, or if we are required to by law. Except where the breach is severe, unlawful, or poses immediate risk, we will give notice and a reasonable opportunity to cure.
On termination, your license to use the Service ends and we may delete your content after the retention periods described in the Privacy Policy. Export your data before you terminate. Sections 9 (your representations), 10, 11, 18, 19, 20, 21, and 23 survive termination.
18.Disclaimers
THE SERVICE AND ALL AI OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT AI OUTPUT WILL BE ACCURATE, COMPLETE, OR SUITABLE FOR YOUR PURPOSE.
Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you; nothing here limits consumer rights that cannot be waived by law.
19.Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER BLUEPRINT NEXUS INC. NOR ITS DIRECTORS, EMPLOYEES, OR SUPPLIERS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, OR BUSINESS INTERRUPTION, ARISING FROM OR RELATING TO THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY.
OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF ONE HUNDRED U.S. DOLLARS ($100) OR THE FEES YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM.
These limits do not apply to liability that cannot be excluded by law, including death or personal injury caused by negligence, fraud, or fraudulent misrepresentation.
Indemnification: you will defend and indemnify us against third-party claims arising from your content, your use of the Service, your violation of these Terms, or your violation of any law or third-party right.
20.Dispute Resolution & Arbitration
Informal resolution first. Before filing a claim, contact wuruosen@gmail.com with a description of the dispute and the relief sought. The parties will attempt in good faith to resolve it for 60 days.
Binding arbitration. If informal resolution fails, any dispute arising out of or relating to these Terms or the Service will be resolved by binding individual arbitration administered by JAMS under its Streamlined Arbitration Rules, seated in Boulder County, Colorado. The arbitrator decides all issues except the enforceability of the class action waiver, which is for a court. Judgment on the award may be entered in any court of competent jurisdiction.
Class action and jury waiver. Disputes will be brought only in an individual capacity, not as a plaintiff or class member in any class, consolidated, or representative action. The parties waive the right to a jury trial.
Exceptions. Either party may bring a claim in small claims court, or seek injunctive relief in court to protect intellectual property or prevent unauthorized access to the Service.
30-day opt-out
You may opt out of this arbitration agreement by emailing wuruosen@gmail.comwith your account email and the words "arbitration opt-out" within 30 days of first accepting these Terms. Opting out does not affect any other part of these Terms.
If you are a consumer in the EEA or UK, this section does not deprive you of the right to bring proceedings in the courts of your country of residence, and mandatory local consumer law applies.
21.Governing Law & Venue
These Terms are governed by the laws of the State of Colorado, United States, without regard to conflict of law principles, and excluding the U.N. Convention on Contracts for the International Sale of Goods. For claims not subject to arbitration, the parties submit to the exclusive jurisdiction of the state and federal courts located in Boulder County, Colorado — except that consumers may bring claims in the courts of their place of residence where local law requires.
22.Export Controls & Sanctions
You must comply with U.S. and other applicable export control and sanctions laws. You may not use the Service if you are located in, or ordinarily resident in, an embargoed jurisdiction, or if you are on a restricted-party list, and you may not export or re-export the Service to any such destination or party.
23.General Terms
- Entire agreement: these Terms and the Privacy Policy are the entire agreement between us regarding the Service and supersede prior discussions.
- Severability: if a provision is held unenforceable, it is modified to the minimum extent necessary and the rest remains in force.
- No waiver: failure to enforce a provision is not a waiver of it.
- Assignment: you may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
- Force majeure: neither party is liable for delays caused by events beyond its reasonable control, including outages of upstream providers.
- Notices: we may send notices to your account email or via in-app notification; send notices to us at wuruosen@gmail.com.
- Relationship: nothing here creates a partnership, joint venture, employment, or agency relationship.
24.Changes to These Terms & Contact
We may modify these Terms. For material changes we will notify registered users by email or in-app notice at least 14 days before they take effect, and will update the "Last Revised" date above. Continued use after the effective date constitutes acceptance; if you do not agree, stop using the Service and cancel your subscription.
