Agreement and closed-alpha access
By accessing or using Echo, you agree to these Terms and the Acceptable Use Policy. If you use Echo for an organization, you represent that you have authority to bind it. If you do not agree, do not use Echo.
- Invitation and age. Echo is private and invitation-only. You must be at least 18 years old and legally able to enter this agreement.
- Credentials. You create an individual account using your email address, a personal password, and an invite code. You must verify your email address. Access is not transferable. Do not disclose your password, invite code, sessions, or API keys to anyone Tracer has not authorized, and notify us promptly of suspected misuse.
- Alpha status. Echo is unfinished and may contain errors, lose features, change without notice, or be unavailable. There is no service-level commitment, support commitment, uptime promise, or obligation to continue the alpha.
- No current charges. Echo is currently free. Any Stripe experience is in test mode and will not result in a charge. We will give notice and request any legally required consent before introducing paid use.
Acceptable use and anti-extraction restrictions
You may use Echo only for authorized alpha evaluation and lawful purposes. You must follow the Acceptable Use Policy and all usage limits we communicate.
You may not, directly or through another person or system:
- systematically harvest, collect, or aggregate outputs, including through automated prompting, scripted probing, bulk querying, or coordinated accounts;
- scrape benchmarks, run automated evaluations, or conduct red-team or load testing without Tracer's prior written authorization;
- use Echo, its outputs, or observations about it to train, distill, validate, evaluate, benchmark, tune, or otherwise improve a competing model, model router, or AI service;
- build or assist an imitation, substitute, or service designed to replicate Echo's behavior, capabilities, routing, presentation, or commercial function;
- reverse engineer, decompile, disassemble, or attempt to discover or infer source code, object code, model weights, system prompts, hidden instructions, routing logic, safety controls, or nonpublic design, except to the limited extent such a restriction is prohibited by law;
- circumvent access controls, safety systems, monitoring, rate limits, usage caps, or technical restrictions, or probe for vulnerabilities without written authorization; or
- share, resell, sublicense, rent, or transfer access, credentials, sessions, or API keys, or offer Echo as a service bureau or resale service.
Ordinary manual evaluation and feedback within your invitation are permitted. Written authorization for broader testing must come from Tracer.
Your content, outputs, and feedback
Input means content you submit to Echo. Output means content Echo returns in response. Together, they are Content.
Ownership
As between you and Tracer, you retain your rights in Input and, to the extent permitted by law, own Output. Tracer assigns to you any right, title, and interest it may have in Output. Output may not be unique, and other users may receive similar content. Your rights do not extend to third-party material or to Echo itself.
License needed to run and improve Echo
You grant Tracer and its service providers a nonexclusive, worldwide, royalty-free license to host, copy, transmit, format, use, and analyze Content as reasonably needed to provide, operate, secure, evaluate, and improve Echo; enforce these Terms; and comply with law. This includes automated evaluation and limited human review. The license lasts for the applicable retention period described in the Privacy Notice.
Your responsibility
You represent that you have the rights and permissions needed to submit Input and allow the uses described here. You are responsible for your Input and your use of Output.
Feedback
If you provide suggestions, evaluations, bug reports, or other feedback, you grant Tracer a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use, reproduce, modify, commercialize, and otherwise exploit it without restriction or compensation. Tracer has no obligation to use feedback.
Alpha confidentiality and intellectual property
Echo and its nonpublic alpha materials are confidential. Confidential information includes unreleased features, nonpublic outputs or demonstrations, performance and evaluation results, documentation, architecture, system behavior, limitations, credentials, and other information that is marked confidential or reasonably should be understood as confidential.
You will use confidential information only to participate in the alpha, protect it with at least reasonable care, and not disclose it publicly or to any unauthorized person. This obligation does not cover information you can document was lawfully public through no breach, already known without restriction, independently developed without the confidential information, or rightfully received from another source. If law requires disclosure, give Tracer advance notice when legally permitted and disclose only what is required.
Tracer and its licensors own Echo, including its software, models, orchestration, interfaces, documentation, trademarks, and underlying technology. Except for the limited right to use Echo under these Terms, no rights are granted by implication or otherwise. Do not remove proprietary notices or use Tracer or Echo branding without permission.
Data use, service providers, and retention
Alpha chats and usage data are retained for product analytics and quality review. Echo currently stores chats in your browser and in Tracer's Supabase and Google Cloud Storage environments. Provider APIs may process Content to generate responses or support Echo's operation.
Retention target. Tracer is targeting a 365-day retention period for alpha chats and associated usage data. Automated deletion and user deletion are not yet fully implemented, so we cannot promise that all copies will be deleted exactly at 365 days or immediately on request. Some information may remain longer while deletion work is completed or where security, legal, backup, or dispute needs require it.
The Privacy Notice explains what we collect, why we use it, recipients, retention, and available privacy rights. Tracer does not sell personal information or share it for cross-context behavioral advertising.
Output limits and higher-stakes use
Echo uses probabilistic systems. Output may be inaccurate, incomplete, outdated, offensive, or unsuitable, and it may confidently state false information. You must evaluate Output for your use case and verify important facts independently.
- Do not rely on Echo as the sole basis for medical, legal, financial, employment, housing, credit, insurance, education, law-enforcement, or other decisions that may materially affect a person.
- Qualified human review is required before any high-stakes or regulated use, along with compliance with all applicable professional duties and laws.
- Echo is not designed for emergencies or as a substitute for professional advice.
- Echo is not a HIPAA-compliant service, and Tracer does not enter into business associate agreements for this alpha. Do not submit protected health information or other regulated or highly sensitive data.
Changes, monitoring, suspension, and termination
Tracer may monitor use and review Content and logs as described in the Privacy Notice to operate and secure Echo, investigate suspected violations, enforce limits, and improve quality. We may rate-limit, restrict, suspend, or terminate access immediately if we reasonably believe use creates risk, violates these Terms, threatens Echo or others, or is inconsistent with the alpha's purpose.
You may stop using Echo at any time. Tracer may change or discontinue any part of Echo and may update these Terms by posting a revised version with a new effective date. Where law requires, we will provide additional notice or obtain consent. Provisions that by their nature should survive termination will survive, including restrictions, confidentiality, ownership, feedback, disclaimers, liability limits, indemnity, and governing law.
Warranty disclaimer and limitation of liability
Warranty disclaimer
To the maximum extent permitted by law, Echo, Content, and all related services are provided “as is” and “as available.” Tracer and its suppliers disclaim all warranties, express, implied, statutory, or otherwise, including merchantability, fitness for a particular purpose, title, noninfringement, accuracy, availability, security, and any warranty arising from course of dealing or usage of trade.
Limitation of liability
To the maximum extent permitted by law, Tracer and its affiliates, officers, directors, employees, agents, licensors, and suppliers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenues, data, goodwill, or business interruption, arising from or related to Echo or these Terms, even if advised of the possibility.
To the maximum extent permitted by law, their total aggregate liability for all claims arising from or related to Echo or these Terms will not exceed the greater of US $100 or the amount you paid Tracer for Echo in the 12 months before the event giving rise to the claim.
These exclusions and limits do not apply to liability that cannot lawfully be excluded or limited, and they apply only to the extent permitted in your jurisdiction. Nothing in these Terms limits non-waivable consumer rights.
Indemnity
To the extent permitted by applicable law, you will defend, indemnify, and hold harmless Tracer and its affiliates, officers, directors, employees, and agents from third-party claims, damages, losses, liabilities, and reasonable legal fees arising from your Input, your use of Output, your violation of these Terms or law, or your infringement of another person's rights. Tracer may control the defense and settlement, and you will reasonably cooperate. You may not settle a claim in a way that admits fault by or imposes obligations on Tracer without written consent.
This section does not require indemnification to the extent a claim results from Tracer's willful misconduct or where indemnification is prohibited by mandatory consumer law.
Export controls and sanctions
You must comply with applicable export-control, import, and economic-sanctions laws. You may not access or use Echo where doing so is prohibited, for a prohibited end use, or on behalf of a person or entity subject to applicable blocking or restricted-party measures. You represent that you are not prohibited from receiving U.S. services under applicable law.
Governing law, courts, and general terms
Delaware law governs these Terms, without regard to conflict-of-laws rules. Subject to the consumer-law caveat below, the state and federal courts located in Delaware will have exclusive jurisdiction over disputes, and you and Tracer consent to their personal jurisdiction.
Mandatory consumer rights. If you are a consumer, this choice of law and forum does not deprive you of protections that cannot be waived under the law of your usual residence. The exclusive-forum clause applies only where lawful, and you may bring a claim in any forum that mandatory law permits or requires.
You may not assign these Terms without Tracer's written consent. Tracer may assign them to an affiliate or in connection with a merger, financing, reorganization, or sale of all or part of its business. If any provision is unenforceable, it will be enforced to the maximum lawful extent and the rest will remain effective. A waiver must be in writing and is not a continuing waiver.
These Terms, the Acceptable Use Policy, and the Privacy Notice are the entire agreement regarding Echo's alpha and supersede prior discussions on that subject. Headings are for convenience only.
