PROBA TERMS OF SERVICE Aurelius Labs, Inc. Version: 2026-08-20 Effective: August 20, 2026 ==================================================================== 1. AGREEMENT These Terms of Service (the "Terms") are a binding agreement between you and Aurelius Labs, Inc., a Delaware corporation ("Aurelius Labs," "we," "us," or "our"), governing access to and use of Proba, including the website at https://proba.aureliusaligned.ai, the Proba web application, API, MCP interface, documentation, and related services (collectively, the "Service"). By creating an account or organization, purchasing credits, confirming a job, or using the Service, you accept these Terms. If you accept on behalf of an entity, you represent that you have authority to bind that entity, and "you" refers to that entity. Aurelius Labs is the merchant of record for purchases from the Service. Third-party payment services act as payment processors and are not parties to these Terms. If you do not agree to these Terms, do not use the Service. ==================================================================== 2. THE SERVICE Proba provides experimental interpretability and analysis tools for machine-learning practitioners. The Service may analyze data, models, or configurations and provide reports, structured data, measurements, or other outputs ("Outputs"). Outputs may be experimental, incomplete, inaccurate, or unsuitable for your intended use. Unless an Output expressly states otherwise, it is unrated and does not include a warranty or claim of calibration, confidence, novelty, causal effect, or actual model outcome. Outputs are decision-support materials, not guarantees, and are not a substitute for your own evaluation, testing, professional judgment, or safety review. You are responsible for decisions made using an Output. We may add, modify, or discontinue features. We will provide reasonable advance notice when a change materially degrades functionality for which you have already paid, unless an urgent legal or security issue requires faster action. ==================================================================== 3. ACCOUNTS AND ORGANIZATIONS You must be at least 18 years old and legally able to enter into a contract. You must provide accurate registration information and keep it current. Service records, including credits, orders, jobs, receipts, payment associations, and usage records, are maintained for the relevant organization. You are responsible for activity authorized through your account or organization and for safeguarding credentials and API keys. Notify contact@aureliusaligned.ai promptly if you believe an account or credential has been compromised. You may not use the Service if doing so would violate applicable trade, export-control, or sanctions law, including if you are subject to a government restriction that prohibits us from providing the Service. ==================================================================== 4. CREDITS 4.1 Nature of credits Credits are prepaid, limited-purpose entitlements to use eligible features of the Service. Credits are recorded in a ledger for the relevant organization. Credits: - may be used only for the Service; - are not transferable or resellable; - have no cash, cryptocurrency, investment, governance, or ownership value; - are not a deposit, security, stored-value account, or claim on any digital asset; and - may be refunded only as provided in the Refund and Cancellation Policy or as required by law. 4.2 Expiration Credits do not expire and are not forfeited for inactivity. If an expiration rule is introduced in the future, it will apply only to credits acquired after the change takes effect and will be announced at least 30 days in advance. 4.3 Ledger adjustments Credits may enter an organization's balance through purchases, promotional or welcome grants, or administrative adjustments. Credits are debited when you confirm a chargeable job. Corrections and restorations are recorded as additional ledger entries rather than by silently altering completed transaction history. ==================================================================== 5. PURCHASES AND PAYMENT 5.1 Prices Credit packs and directly paid jobs, where offered, are sold at the prices displayed before purchase. Prices are stated in United States dollars unless the checkout page clearly states another currency. You may not choose an arbitrary pack price or credit amount unless the Service expressly offers that option. 5.2 Completing a payment Payment details are entered through a payment service. We do not store full card numbers or card security codes. A purchase is complete only after we receive and verify confirmation of successful payment. A return or success page by itself does not prove that payment succeeded. If a payment succeeds but the corresponding credits or job do not appear within a reasonable period, contact contact@aureliusaligned.ai. 5.3 Saved payment methods and direct job payments If the Service permits you to save a payment method, you authorize the payment service and us to use its resulting identifier only for charges you expressly initiate or automatic purchases you separately enable. Each directly paid job must be confirmed by you unless it is funded by an automatic purchase authorization described in Section 6. 5.4 Taxes Prices are exclusive of taxes unless stated otherwise. Applicable sales, use, value-added, or similar taxes will be shown before payment when we are required to collect them. You remain responsible for taxes that applicable law places on you. ==================================================================== 6. OPTIONAL AUTOMATIC CREDIT PURCHASES If the Service offers automatic credit purchases, the feature is disabled until you opt in and choose the available settings. By enabling it, you authorize a one-time charge for the selected credit pack when your configured balance condition is met. An automatic credit purchase is not a subscription. It has no fixed billing cycle or minimum term and is triggered only under the settings you authorize. You may disable it at any time for future charges. If an automatic purchase is made after you disabled it or contrary to the settings you authorized, the Refund and Cancellation Policy applies. ==================================================================== 7. PRICING CHANGES The price or credit cost shown when you confirm a purchase or job is the price that applies to that transaction. Later pricing changes do not retroactively re-price a completed transaction. We will provide reasonable advance notice of material pricing changes. ==================================================================== 8. REFUNDS AND CANCELLATION Refunds, credit restorations, and compensation for failed or partially completed work are governed by the Proba Refund and Cancellation Policy at https://proba.aureliusaligned.ai/refund-policy, which forms part of these Terms. Among other protections, that policy provides that: - credits charged for failed, cancelled, or timed-out undelivered work are restored; - a directly paid job that fails while running is refunded to the original payment method; - partial compensation may be issued as credits; and - unused purchased credits may be refunded on request within 14 days after purchase. ==================================================================== 9. CUSTOMER DATA "Customer Data" means datasets, prompts, model references, configuration, files, and other materials you submit to the Service. As between you and Aurelius Labs, you retain your rights in Customer Data. We do not claim ownership of it. You grant Aurelius Labs a non-exclusive, worldwide license to host, process, transmit, reproduce, and analyze Customer Data only as needed to provide, maintain, secure, and support the Service, comply with law, and follow your instructions. This license ends when the Customer Data is deleted, except to the limited extent continued retention is permitted under the Privacy Policy or required by law. We do not use Customer Data to train or fine-tune any model, instrument, or product. We do not disclose Customer Data to other customers or to public blockchain or subnet participants. You represent that you have all rights and permissions needed to submit Customer Data and to instruct us to process it. Customer Data must not violate law, these Terms, or a third party's rights. Do not submit protected health information, payment-card data, government-classified information, or information subject to incompatible contractual or regulatory restrictions unless we agree in writing to the required handling terms. Our collection, retention, and deletion of personal information is described in the Privacy Policy at https://proba.aureliusaligned.ai/privacy. ==================================================================== 10. OUTPUTS AND SERVICE RIGHTS Subject to your payment obligations and any third-party rights, as between you and Aurelius Labs, you own the Outputs generated specifically for your organization and may use them for lawful purposes. Aurelius Labs and its licensors retain all rights in the Service, including software, models, instruments, methods, interfaces, documentation, templates, and technology used to generate Outputs. Similar or identical Outputs may be generated for different customers, and no Output gives you exclusivity over underlying methods, concepts, or information. Feedback may be used to improve the Service without restriction or payment, provided we do not publicly identify you as its source without permission. ==================================================================== 11. ACCEPTABLE USE You may not: - use the Service or Outputs to violate law or the rights of others; - submit unlawful, malicious, infringing, or unauthorized material; - attempt to gain unauthorized access to accounts, systems, models, credentials, or infrastructure; - disrupt the Service, bypass rate limits or security controls, or impose an unreasonable load; - reverse engineer, decompile, or attempt to extract non-public source code, model weights, instruments, or security mechanisms, except to the extent a restriction is prohibited by law; - share credentials across unrelated organizations or create duplicate organizations to obtain additional promotional grants; - resell or provide the Service as a standalone service without our written permission; or - use the Service to develop, train, or deploy systems intended to cause harm or evade another system's safety measures. We may suspend access immediately when we reasonably believe continued access poses a legal, security, fraud, abuse, or operational risk. Where practicable, we will provide notice and an opportunity to cure a remediable violation. ==================================================================== 12. SERVICE AVAILABILITY We aim to keep the Service available and reliable but do not promise a specific uptime level under these Terms. Maintenance, failures, capacity limits, third-party services, and events outside our control may affect availability. The Refund and Cancellation Policy governs paid work that we fail to deliver. ==================================================================== 13. CONFIDENTIALITY Each party may receive non-public information of the other that is identified as confidential or should reasonably be understood as confidential. The receiving party will protect it with at least reasonable care, use it only to perform or exercise rights under these Terms, and disclose it only to personnel and service providers bound by appropriate confidentiality obligations. These obligations do not apply to information that the receiving party can show was lawfully known without restriction, independently developed, rightfully received from another source without restriction, or made public without breach of these Terms. Disclosure required by law is permitted, with advance notice where legally allowed. Customer Data is your confidential information. ==================================================================== 14. DISCLAIMERS TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE AND OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE." AURELIUS LABS DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT OUTPUTS WILL BE ACCURATE, COMPLETE, CALIBRATED, OR PREDICTIVE OF ACTUAL MODEL BEHAVIOR, OR THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE. THESE DISCLAIMERS DO NOT LIMIT A WARRANTY OR RIGHT THAT CANNOT LAWFULLY BE DISCLAIMED. ==================================================================== 15. LIMITATION OF LIABILITY TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, OR THE COST OF SUBSTITUTE SERVICES, EVEN IF ADVISED OF THE POSSIBILITY. TO THE MAXIMUM EXTENT PERMITTED BY LAW, AURELIUS LABS' TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID AURELIUS LABS FOR THE SERVICE DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR (B) ONE HUNDRED UNITED STATES DOLLARS (US $100). The exclusions and limits in this section do not apply to payment obligations, breach of confidentiality, infringement or misappropriation of the other party's intellectual-property rights, indemnification obligations, fraud, willful misconduct, or liability that cannot be limited by law. ==================================================================== 16. INDEMNIFICATION You will defend and indemnify Aurelius Labs and its officers, directors, employees, and agents against third-party claims arising from Customer Data, your violation of these Terms, or your violation of applicable law or a third party's rights. Aurelius Labs will defend and indemnify you against a third-party claim that the Service, as provided by us and used in accordance with these Terms, infringes a United States patent, copyright, or trademark. This obligation does not apply to claims arising from Customer Data, modifications not made by us, combination with items not supplied by us, or continued use after we provide a non-infringing alternative. The indemnified party must promptly notify the indemnifying party, permit it to control the defense and settlement, and provide reasonable cooperation. A settlement may not admit fault or impose a non-monetary obligation on the indemnified party without its consent. ==================================================================== 17. TERM, SUSPENSION, AND TERMINATION These Terms remain in effect while you have an account, organization, credit balance, or continuing use of the Service. You may stop using the Service and request organization closure at any time. We may terminate these Terms for a material breach that remains uncured 30 days after written notice, or immediately when permitted by Section 11 or when continued service would violate law. Closure may remain pending while a payment, refund, automatic purchase, dispute, security review, legal hold, or deletion obligation is in progress. After termination, access ends and Customer Data is handled under the Privacy Policy. Remaining credits are handled under the Refund and Cancellation Policy. Sections that by their nature should survive will survive, including Sections 9, 10, and 13 through 19. ==================================================================== 18. CHANGES TO THESE TERMS We may update these Terms. Each published version identifies its effective date. We will provide at least 30 days' advance notice of a material change by email, through the Service, or by another reasonable method, unless a shorter period is required to address an urgent legal or security issue. Continued use after the effective date of updated Terms constitutes acceptance. If you do not accept a material change, you may stop using the Service and request a refund of unused purchased credits under the Refund and Cancellation Policy. ==================================================================== 19. GENERAL Governing law and venue. These Terms are governed by the laws of the State of Delaware, without regard to conflict-of-laws principles. The parties consent to exclusive jurisdiction and venue in the state and federal courts located in Delaware. Relationship to decentralized networks. Proba is a commercial software service operated by Aurelius Labs. Nothing in these Terms offers, sells, or promises a digital asset, token, protocol right, ownership interest, governance right, or entitlement to network rewards. Entire agreement. These Terms, the Privacy Policy, the Refund and Cancellation Policy, and any order or written addendum agreed by the parties are the entire agreement concerning the Service and supersede prior discussions on that subject. If an order or addendum conflicts with these Terms, the order or addendum controls for that conflict. Assignment. You may not assign these Terms without our written consent. We may assign them in connection with a merger, acquisition, reorganization, or sale of assets, or to an affiliate that can perform our obligations. Severability; waiver. If a provision is held unenforceable, it will be modified to the minimum extent necessary and the remaining provisions will remain effective. Failure to enforce a provision is not a waiver. Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control, except for payment obligations. Notices. You may send legal notices to the contact in Section 20. We may send notices to the email address associated with your account or through the Service. ==================================================================== 20. CONTACT Aurelius Labs, Inc.
