IMPORTANT: This Agreement governs your access to the Sentinel CPO executive performance service, beginning with a 30-Day Calibration Pilot. By completing the checkout process and activating your pilot, the individual Client agrees to be bound by these Terms in their entirety. If you do not agree, do not proceed with activation.
This Terms of Service Agreement ("Agreement") is entered into between Sentinel CPO LLC, a Connecticut limited liability company ("Sentinel CPO," "we," "us," or "our"), and the individual or business entity completing the enrollment process ("Client," "you," or "your").
This Agreement governs your access to and use of the Sentinel CPO platform, including all software, AI-generated outputs, biometric integrations, hardware components, and ancillary services (collectively, the "Service").
Geographic Scope. The Sentinel CPO Service is offered exclusively to individuals located in the United States of America. Sentinel CPO LLC does not knowingly offer or market the Service to individuals located in the European Union, European Economic Area, or United Kingdom. By completing enrollment, you represent that you are physically located within the United States and that the EU General Data Protection Regulation (GDPR) and UK GDPR do not apply to your use of the Service.
Sentinel CPO provides an algorithmic professional performance optimization platform designed exclusively for use by C-Suite executives and senior business operators in a strictly professional context. Sentinel CPO does not diagnose, treat, cure, prevent, or mitigate any disease, disorder, or medical condition, and makes no health claims of any kind.
Client expressly acknowledges the above limitations and the non-medical, non-health-claims nature of the Service as a material condition of activating the Service.
Subject to the terms herein and confirmed payment of all fees, Sentinel CPO grants Client a non-exclusive, non-transferable, non-sublicensable license to access and use the Service for Client's internal professional optimization purposes during the Subscription Term. Access to the Client Portal is not granted until initial payment is confirmed by Sentinel CPO's payment processor. No portal access exists in a payment-pending state.
Service begins with a 30-Day Calibration Pilot at a one-time fee as specified at the time of checkout ("Activation Date"). On Day 31, the Service automatically graduates to Phase 1 Foundation at $995.00 USD per month, billed monthly on a rolling basis. Phase 1 is a purely month-to-month arrangement — there is no annual commitment and no minimum duration.
Auto-Graduation Notice. Sentinel CPO will send a written reminder to the email address on file no fewer than five (5) calendar days before the first Phase 1 charge. Phase 1 billing will proceed on Day 31 consistent with the terms accepted at enrollment. To prevent Phase 1 billing, the Client must use the Pause control in the Client Portal before Day 31.
Cryo-Sleep vs. Full Cancellation. At any time after Phase 1 begins, the Client may choose between two options: (a) Cryo-Sleep (Vault Preservation) — pauses active service at the end of the current billing period at a reduced vault preservation fee of $295.00 USD per month; full service access (briefings, check-ins, and daily prompts) is suspended during Cryo-Sleep, but all platform data is retained in encrypted storage; the Client may reactivate at any time from the Client Portal, at which point billing resumes at the applicable Phase rate; or (b) Cancel (Full Termination) — permanently terminates the license at the end of the current billing period; all Client data is subject to the 30-day Ephemeral Liquidation protocol and is irreversibly deleted thereafter. Cancellation cannot be undone once the 30-day window closes. There is no early termination fee for entering Cryo-Sleep or for cancelling.
The license is granted to a single executive user. Sharing access credentials, reselling access, or allowing use by unauthorized parties constitutes a material breach of this Agreement.
Upon enrollment, Client is assigned a permanent pseudonymous Client ID (e.g., CPO-XXXX). This identifier is used across all platform intelligence operations in lieu of the Client's real name. Client's name and contact information are collected solely for hardware shipping, billing, and legal agreement execution, and are not used in AI processing, briefing generation, or quality review. The Client ID is referenced in all delivered documents, including Sunday Briefings and Baseline Assessments.
Sentinel CPO offers a Trial Enrollment ("Trial") as an introductory product that allows prospective Clients to experience the platform's AI voice check-in intelligence and cognitive brief synthesis capabilities.
The Trial is a seven (7) day standalone product. The Trial does not automatically convert or roll into the 30-Day Calibration Pilot or any other Service tier. Enrollment in the Calibration Pilot after the Trial concludes is a separate, voluntary decision made by the participant and requires a separate, explicit enrollment action. The Trial and Calibration Pilot together constitute the full onboarding sequence; Phase 1 Foundation is not available until the 30-Day Calibration Pilot has been completed. Trial participants are governed by this Section 3.5; all other terms of this Agreement apply to Trial participants only as expressly stated herein.
The Trial is offered at a one-time fee of $299.00 USD, charged at the time of signup. This fee is non-refundable and is a standalone charge for the Trial product only. It does not reduce or credit toward the Calibration Pilot fee or any Phase 1 subscription fees.
Upon completing the Trial signup and providing clickwrap consent, participants receive: (a) one (1) AI-guided diagnostic session, accessible via a unique email-linked portal page (no account login required), to open the participant's performance record; (b) seven (7) daily AI voice check-in sessions, each accessible via a unique email-linked portal page (no account login required), conducted over seven (7) consecutive days; and (c) one (1) Executive Cognitive Brief, synthesized by AI on Day 7 and delivered to the participant's email address.
Non-Transferable Access. Each email-linked session page is personal and non-transferable. Trial participants may not forward, share, or otherwise transfer access links to any third party. Use of the Service by any person other than the registered Trial participant constitutes a material breach of this Agreement, and Sentinel CPO reserves the right to terminate the Trial without refund upon detection of unauthorized use.
Trial participants may optionally connect an existing Oura Ring to the platform. If connected, biometric telemetry (as enumerated in the Biometric Privacy Policy, Section 2) is collected and integrated into the Day 7 Executive Cognitive Brief. No biometric hardware is procured or shipped by Sentinel CPO as part of the Trial. Oura connection is not required — the Trial and Day 7 brief are delivered with or without biometric integration.
The Trial expires at the conclusion of Day 7. No charge is assessed beyond the one-time $299 Trial fee unless the participant takes an explicit, affirmative enrollment action. If a participant elects to enroll in the Calibration Pilot following the Trial, the applicable Calibration Pilot fee is charged at that time as a separate transaction. Two enrollment tracks are available: (a) Ring Included, which includes an Oura Ring 4 shipped to the participant's address; and (b) Own Ring, for participants who already own an Oura Ring Gen3 or Gen4. Track selection and pricing are presented to the participant at the time of enrollment. The $299 Trial fee does not credit toward or reduce the Calibration Pilot fee under either track.
Trial participants are not assigned a pseudonymous CPO-XXXX Client ID (described in Section 3.4). During the Trial, participants are identified in Sentinel CPO's systems by an internal enrollment ID generated at signup. The CPO-XXXX identifier is assigned only upon commencement of the Calibration Pilot. This enrollment ID is not shared with or disclosed to any third party except as required for Service delivery.
If the participant enrolls in the Calibration Pilot following the Trial, Trial diagnostic responses, session performance metadata, and (if applicable) biometric telemetry are carried forward and incorporated into the Client's platform record, subject to the retention terms in this Agreement. If the participant does not enroll, all Trial data is permanently deleted within 30 days of the Trial expiration date pursuant to the Ephemeral Data Lifecycle. Trial data is never used for any purpose beyond the Trial and subsequent Service delivery.
Trial participants provide clickwrap consent at signup, expressly acknowledging: (a) the standalone nature of the Trial — it does not automatically convert to any subscription or ongoing service; (b) the non-refundable Trial fee and its separate, non-crediting status; (c) the non-transferability of access links; (d) the data collection and retention practices described herein and in the Biometric Privacy Policy; and (e) the non-medical nature of all Trial outputs as described in Section 2 of this Agreement.
Upon license activation, Sentinel CPO coordinates the procurement and delivery of a biometric monitoring ring (Oura Ring, sourced via Oura Health Oy) to the Client's designated shipping address. Title to the hardware passes to Client upon delivery.
The Calibration Pilot fee (in the amount specified at checkout) covers hardware deployment, logistics, and the first 30 days of service. This fee is non-refundable once checkout is completed and hardware deployment has been initiated (or portal access has been activated, for clients who provide their own hardware). There is no early termination fee for pausing Phase 1 after the pilot concludes.
On each 12-month anniversary of the Client's subscription start date, provided the Client's subscription remains active and in good standing, Sentinel CPO LLC will apply a $995.00 USD 12-Month Loyalty Credit to the Client's next invoice. The credit vests only upon generation of the invoice immediately following the anniversary date while the subscription remains active. The 12-Month Loyalty Credit applies to all active subscription tiers (Phase 1, Phase 2, Phase 3) and to Cryo-Sleep vault preservation invoices. Any credit balance remaining after application to an invoice carries forward to subsequent invoices until fully applied or the subscription is terminated.
The 12-Month Loyalty Credit has no cash value, is not redeemable for cash or gift cards, and is non-transferable. Credits not applied due to subscription termination prior to invoice generation are forfeited with no cash equivalent owed. The 12-Month Loyalty Credit is a promotional benefit earned through continued active subscription and does not constitute a stored value product or gift card under applicable state law.
The Service requires an active Oura Ring membership subscription (provided by Oura Health Oy, independently of this Agreement) to access full biometric data capabilities. The Oura membership and all associated fees are the Client's sole responsibility. Sentinel CPO LLC does not pay for, manage, or guarantee the availability of the Client's Oura membership. If the Client's Oura membership lapses or is cancelled, biometric data collection will be interrupted and briefing quality may be materially degraded. Such interruptions attributable to the Client's lapsed Oura membership do not constitute a breach of this Agreement by Sentinel CPO LLC and do not entitle the Client to any refund, credit, or service adjustment.
The initial Oura Ring deployed at enrollment is procured by Sentinel CPO LLC on the Client's behalf. Title passes to the Client upon delivery. Oura Health Oy's standard manufacturer warranty covers the ring against defects in materials and workmanship; warranty coverage follows the physical product and protects the Client regardless of the original purchaser of record. At the time of shipment, Sentinel CPO LLC will provide the Client with the Oura order reference number to facilitate direct warranty inquiries.
Sentinel CPO LLC will facilitate manufacturer warranty claims on the Client's behalf for the duration of the manufacturer's warranty period (currently one year from date of shipment), including after termination of this Agreement. The Client is not required to return hardware to Sentinel CPO LLC — all physical logistics are coordinated directly between the Client and the manufacturer. In the event a warranty claim results in a replacement being issued and the Client fails to return the original hardware to the manufacturer within the required timeframe, the Client authorizes Sentinel CPO LLC to charge the Client's payment method on file for the manufacturer's replacement cost plus any associated shipping fees incurred by Sentinel CPO LLC. Loss of the initial hardware is the Client's responsibility once title has transferred; the 12-Month Loyalty Credit is not accelerated in the event of hardware loss.
The Calibration Pilot fee is as specified at the time of checkout, charged once at checkout. Phase 1 Foundation is billed at $995.00 USD per month beginning on Day 31, charged monthly to the payment method saved at checkout. All fees are non-refundable except as expressly stated herein.
Access to the Service is conditioned on successful payment at all times. For new enrollments, access is not granted until initial payment is confirmed (see Section 3.1). For recurring billing, Client's continued access to the Service is contingent on each monthly payment clearing successfully — any future lapse in payment will result in immediate suspension of access for the duration of the lapse. Sentinel CPO will attempt to collect payment up to three (3) times over a seven (7) day period; access is restored only upon confirmed payment clearance. If payment is not resolved within 14 days of the initial failure, Sentinel CPO reserves the right to terminate the license.
All fees stated in this Agreement are all-inclusive. Sentinel CPO LLC is registered in Connecticut for Sales and Use Tax purposes. Connecticut classifies SaaS subscriptions as "Computer and Data Processing Services" and applies sales tax based on subscriber type: 6.35% for individual (consumer/B2C) subscribers and 1.0% for corporate or business (B2B) subscribers. Sentinel CPO LLC captures subscriber type at checkout to apply the correct rate. Rather than adding a separate tax line to invoices, Sentinel CPO LLC remits Connecticut sales tax on applicable transactions from its own collected revenue. Clients pay the stated all-inclusive fee with no additional tax charge at checkout or on recurring invoices. Clients outside Connecticut are not subject to Connecticut sales tax; Sentinel CPO LLC may collect tax in other states if and when economic nexus thresholds are triggered in those jurisdictions.
Sentinel CPO may modify subscription fees upon thirty (30) days written notice prior to the next renewal term. Continued use of the Service following such notice constitutes acceptance of the revised fees.
Client agrees to:
Sentinel CPO retains all right, title, and interest in and to the Service, including all software, AI models, proprietary methodologies, prompt engineering frameworks, and platform architecture. Nothing in this Agreement transfers any intellectual property rights to Client.
Client retains ownership of all personal data, assessment responses, and biometric telemetry submitted to the Service. Daily check-in sessions are conducted via a real-time AI voice conversation; no audio recordings or transcripts of those sessions are stored by Sentinel CPO. Structured session performance metadata extracted from each session is stored in encrypted form and subject to the Ephemeral Data Lifecycle described in our Ephemeral Data Architecture policy. Client grants Sentinel CPO a limited, non-exclusive license to process such data solely for the purpose of providing the Service.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SENTINEL CPO LLC AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Sentinel CPO's total cumulative liability to Client for any claim arising under or related to this Agreement shall not exceed the total fees paid by Client to Sentinel CPO in the twelve (12) months immediately preceding the event giving rise to the claim.
This limitation applies regardless of the theory of liability (contract, tort, strict liability, or otherwise) and survives the termination of this Agreement.
Client agrees to indemnify, defend, and hold harmless Sentinel CPO LLC and its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, judgments, awards, losses, costs, or expenses (including reasonable attorneys' fees) arising out of or relating to: (a) Client's use or misuse of the Service; (b) Client's violation of this Agreement; (c) Client's violation of any applicable law or regulation; or (d) any claim that Client's use of the Service harmed a third party.
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND. SENTINEL CPO EXPRESSLY DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
Sentinel CPO does not warrant that: (a) the Service will meet Client's specific requirements; (b) AI-generated outputs will be error-free or achieve any particular professional outcome; (c) biometric data interpretations will be medically accurate; or (d) the Service will be uninterrupted or continuously available.
The Service integrates with third-party technology providers — including biometric monitoring hardware, AI inference services, voice processing infrastructure, and cloud platform providers — to deliver its functionality. Sentinel CPO LLC does not warrant the availability, accuracy, security, or continued operation of any third-party service. Temporary interruptions attributable to third-party providers do not constitute a breach of this Agreement by Sentinel CPO LLC.
Sentinel CPO LLC reserves the right to substitute, replace, or discontinue any third-party integration at any time without prior notice to Client, provided that any such change does not materially degrade the core functionality of the Service. Client's continued use of the Service following any such substitution constitutes acceptance of the change. Where a substitution materially affects the processing of Client biometric data, Sentinel CPO LLC will provide written notice and an opportunity to terminate without penalty.
Each third-party provider integrated into the Service operates under its own independent terms of service and privacy policies. Sentinel CPO LLC maintains contractual restrictions with such providers governing their use of Client data. However, Sentinel CPO LLC cannot warrant or assume liability for any third party's independent compliance with its own policies or applicable law. A complete disclosure of current third-party sub-processors — including the data each receives, their jurisdiction, and applicable data residency — is available at sentinelcpo.com/sub-processors. Enterprise clients and corporate sponsors requiring a Data Processing Agreement may request one at sentinelcpo.com/data-processing-agreement.
The Sentinel CPO website and service interfaces may feature AI-assisted tools, including a sales information assistant available to prospective and active Clients. Information provided by such tools is generated by automated artificial intelligence systems and is for general informational purposes only. It does not constitute a binding offer, representation, warranty, or contractual term, and does not modify or supplement this Agreement. In any conflict between information provided by an AI-assisted tool and this Agreement or the Private Client Agreement, the written legal documents govern.
Cryo-Sleep (Vault Preservation). Client may enter Cryo-Sleep at any time via the Client Portal. Cryo-Sleep activates at the end of the current billing period; full service access continues until that date. During Cryo-Sleep, billing continues at a reduced vault preservation rate of $295.00 USD per month; briefings, check-ins, and daily prompts are suspended. All Client data is retained in encrypted storage. The Client may reactivate at any time from the Client Portal, at which point billing resumes at the applicable Phase rate. There is no early termination fee for entering Cryo-Sleep.
Cancel (Full Termination). Client may permanently cancel the Service at any time via the Client Portal. Cancellation takes effect at the end of the current billing period; full access continues until that date. Upon cancellation, all Client data is subject to the 30-day Ephemeral Liquidation protocol and is permanently and irreversibly deleted thereafter. There is no early termination fee for Phase 1 cancellation. The Calibration Pilot fee is non-refundable as described in Section 4.2.
Sentinel CPO may terminate this Agreement immediately upon written notice if Client: (a) materially breaches this Agreement and fails to cure such breach within ten (10) days of notice; (b) becomes insolvent or subject to bankruptcy proceedings; or (c) engages in conduct that Sentinel CPO reasonably determines poses a legal, reputational, or security risk.
Upon termination: (a) all license rights granted hereunder immediately cease; (b) Client's access to the platform is revoked; (c) all Client data is subject to the Ephemeral Data Lifecycle described in our Ephemeral Data Architecture policy.
This Agreement is governed by the laws of the State of Connecticut, without regard to conflict of law principles. Any dispute arising under or related to this Agreement shall be resolved by binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules, with proceedings conducted in English in Hartford, Connecticut. The arbitrator's decision shall be final and binding. Each party waives any right to a jury trial.
Notwithstanding the foregoing, either party may seek injunctive or other equitable relief in any court of competent jurisdiction to prevent unauthorized use of intellectual property or confidential information.
Class Action and Representative Proceeding Waiver. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, CLIENT WAIVES ANY RIGHT TO INITIATE, JOIN, OR PARTICIPATE IN ANY CLASS-ACTION LAWSUIT, CLASS-WIDE ARBITRATION, PRIVATE ATTORNEY GENERAL ACTION, OR ANY OTHER REPRESENTATIVE PROCEEDING AGAINST SENTINEL CPO LLC. ALL CLAIMS MUST BE BROUGHT ON AN INDIVIDUAL BASIS ONLY. This waiver is governed by the Federal Arbitration Act (9 U.S.C. § 1 et seq.), which preempts any contrary state law pursuant to AT&T Mobility LLC v. Concepcion, 563 U.S. 333 (2011), and Epic Systems Corp. v. Lewis, 584 U.S. 497 (2018). If a court of competent jurisdiction holds that this waiver is unenforceable as to a specific claim or in a specific jurisdiction notwithstanding FAA preemption, only that specific claim may be adjudicated on a class basis in a court of competent jurisdiction; all other claims remain subject to individual arbitration and this waiver. The severance of one application of this waiver does not affect its validity as to all other claims or jurisdictions.
Entire Agreement. This Agreement, together with the Private Client Agreement (Enterprise License Agreement), the Biometric Privacy Policy, the Ephemeral Data Architecture policy, and any applicable Phase Upgrade Agreement, constitutes the entire agreement between the parties with respect to the Service and supersedes all prior understandings, representations, negotiations, and agreements — whether written or oral — relating to the same subject matter.
Severability. If any provision of this Agreement is found unenforceable, it shall be modified to the minimum extent necessary to make it enforceable, and all remaining provisions shall remain in full force.
Waiver. No failure or delay by either party to enforce any right hereunder shall constitute a waiver of such right.
Assignment. Client may not assign this Agreement without Sentinel CPO's prior written consent. Sentinel CPO may assign this Agreement in connection with a merger, acquisition, or sale of substantially all of its assets.
Notices. All legal notices shall be sent to Sentinel CPO LLC via the Legal inquiry form at sentinelcpo.com/contact.
