Terms of service

I. These terms

These terms are an agreement between you and Sieve Data Inc., a Delaware corporation (“we”) about your use of Vibrometer: the website at vibrometer.ai, its Olympiad, Pantheon, groups and Patrons pages, the vibrometer command-line tool and the Claude Code plugin. By using Vibrometer you agree to them. Our privacy policy explains how we handle personal data.

You must be at least 16 to use Vibrometer. If you use it for an organisation, you confirm you may accept these terms for it.

II. The service

Vibrometer measures how people work with AI coding agents from their session transcripts, and runs timed challenges graded with hidden tests. It is new and changes often: we may add, change or remove features, reset or re-score results when scoring changes (scores ship in seasons), and pause the service. Scores, vibe types and rankings describe habits; they are not a professional assessment of anyone’s ability.

Claude Code, Codex and other products named on the site belong to their owners. Unless we say so, Vibrometer is independent of them and not endorsed by them.

III. Your account

Keep one account per person, give accurate information, and keep your sign-in methods secure. You are responsible for what happens under your account, including uploads from a computer you approved for the CLI. A new or changed handle needs 4 to 30 characters, and some names are reserved (for example ones containing “sieve” or “vibrometer”, and the site’s own page names). Handles, names and group names must not impersonate anyone, mislead, or be offensive; we may change or remove them.

IV. What you may upload

Before any conversation is uploaded, you confirm: I’m allowed to upload these conversations, and they don’t contain sensitive, confidential or illegal material (such as credentials, other people’s personal data, or code I’m not permitted to share). That confirmation is part of these terms. In particular, don’t upload:

• conversations you have no right to share, such as an employer’s or client’s confidential code or documents you aren’t permitted to share;
• credentials, keys or other secrets (we try to remove them, but can’t catch everything);
• other people’s personal data, health, financial or other sensitive information;
• anything illegal, or anything that infringes someone else’s rights.

If you aren’t sure, leave the conversation out or use private mode, which sends only numbers.

V. Your content, and the licence you give us

You keep every right you have in your conversations, code, prompts and profile. You give us a worldwide, non-exclusive, royalty-free licence to host, copy, process, analyse and measure them, and to display your handle, profile, measurements, vibe type and results, as needed to run Vibrometer and to show what you choose to publish (the boards, share links, groups and, if you turn it on, the Patrons page). If you tick an optional box when uploading, you also give the licence that box describes.

The licence ends when you delete the content or your account, except for: share links you already sent (the numbers are in the link), aggregate findings that can’t identify you, and backups until they expire.

Code you submit to a challenge is graded in a sandbox and kept with your entry; we may review it to check fair play.

VI. Acceptable use

Don’t:

• forge, edit or synthesise transcripts or results, or claim conversations that aren’t yours;
• break, probe or overload the service, get around its limits or checks, or access other people’s accounts or data;
• scrape the site beyond what robots.txt allows, or collect other people’s data from it, including from the Patrons page, for anything but recruiting them personally;
• use Vibrometer to harass, spam or discriminate against anyone, or to break the law;
• create accounts automatically or in bulk, or sell or transfer an account.

VII. Olympiad fair play

The Olympiad measures how well you direct a coding agent. For an attempt to count toward rankings:

• You must lead the work yourself. Don’t let an AI solve a ranked challenge alone, or have another person or another agent session direct it for you. A session without meaningful direction from you is graded as practice, not ranked.
• Don’t bring a pre-written solution, paste in someone else’s, or share a challenge’s brief, hidden tests or solutions with others.
• Don’t change or delete the provided tests to pass them, or hard-code expected outputs.
• Only your first attempt at each challenge is ranked. Use one account.

We check sessions automatically and may review them by hand. We may mark an entry as practice, remove it from the standings, or suspend an account that breaks these rules. Using AI is the point; letting it work without you isn’t.

VIII. Boards, share links and public pages

The boards and share links are public: anyone can see what is on them (see what other people can see). The Patrons page’s candidate list is not: only employers we have given an access code can see it. Rankings may change at any time, for example when results are re-scored or checked. We may remove entries, handles or groups that break these terms. Share links carry their data in the link, so we can’t take back a link you have sent.

IX. Patrons and employers

People who turn on “open to work” are listed on the Patrons page with their profile, GitHub username, measurements and Olympiad results. Only employers we have given an access code can see that list; we may refuse, limit or withdraw access at any time. You can ask for a code at hello@usesieve.com.

If you are given access: keep the code to your organisation and don’t share it, or the candidate data, with anyone else; use what you see only to contact people about roles; follow the law (including anti-discrimination and data protection law); and don’t treat a score as the sole basis of a hiring decision. People listed there chose to be; respect it if they don’t reply. We don’t vouch for any candidate or employer.

If you are open to work: only employers with access see your candidate profile, and you can turn it off in your profile at any time.

X. The CLI and the plugin

The command-line tool and the Claude Code plugin run on your computer and read the transcripts you point them to. They upload nothing unless you confirm with the flags they ask for. You use them at your own risk, as with any software you install.

XI. Credits

Credits unlock extras on the site. They have no cash value, can’t be bought, sold or transferred, and may change or expire if the feature changes.

XII. Feedback

If you send us ideas or suggestions, we may use them without owing you anything.

XIII. No warranty

Vibrometer is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy of scores, and uninterrupted or error-free operation, to the fullest extent the law allows.

XIV. Limitation of liability

To the fullest extent the law allows, we aren’t liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, data, opportunities or goodwill, arising from your use of Vibrometer. Our total liability for any claim about Vibrometer is limited to the greater of what you paid us in the 12 months before the claim and US$100. Nothing in these terms limits liability that can’t be limited by law, such as for death or personal injury caused by negligence, or for fraud, and consumers keep the rights their local law gives them.

XV. Ending

You can stop using Vibrometer and delete your account at any time from your account page. We may suspend or close an account that breaks these terms, or end the service, with notice where we reasonably can. The sections on your content, no warranty, limitation of liability and governing law survive.

XVI. Changes to these terms

We may change these terms. We update the date and version at the top, and tell you in advance of significant changes. If you keep using Vibrometer after a change applies, the new terms apply; if you don’t agree, stop using it and delete your account.

XVII. Governing law and disputes

These terms are governed by the laws of the State of New York, USA, without regard to its conflict-of-laws rules, and disputes are heard by the state or federal courts located in New York County, New York, USA, except where the law of the country you live in gives you, as a consumer, the right to the protection of its laws or to bring proceedings in its courts.
