Terms & Conditions

LAST UPDATED · 1 SEPTEMBER 2026

These Terms & Conditions ("Terms") govern your access to and use of the FHERMA platform at fherma.io (the "Platform") and your participation in any challenge run on it (a "Challenge"). The Platform is operated by Fair Math, Inc., a Delaware corporation with its registered office at 1111B South Governors Avenue, Dover, Delaware 19904, United States ("Fair Math", "we", "us"). By creating an account, submitting a solution, or otherwise using the Platform, you agree to these Terms. If you do not agree, do not use the Platform.

In these Terms, "include" and "including" mean "including without limitation".

Changes to these Terms

We may update these Terms from time to time. The current version is always published on fherma.io, and material changes take effect when posted. Where a change is significant we will make reasonable efforts to notify registered users. Your continued use of the Platform after a change takes effect means you accept the revised Terms. We may also limit, suspend, or discontinue any part of the Platform or a Challenge at any time.

What FHERMA is

FHERMA is an open platform for cryptographic computation: a place to publish kernel specifications, contribute implementations, and take part in benchmarking challenges. Some Challenges offer compensation for the best qualifying solutions. The specifics of each Challenge — its scope, rules, timing, and any prize — are stated on that Challenge's page and form part of these Terms for that Challenge.

Eligibility

To use the Platform and take part in a Challenge you must:

  • be at least 18 years old;
  • be able to form a binding contract with us; and
  • not be prohibited from participating by any applicable law, or by any non-competition, non-disclosure, or similar obligation you are bound by.

We may refuse, suspend, or terminate access, and withhold any compensation, if we reasonably believe you do not meet these requirements.

Accounts

You register with a username (your FHERMA user ID) and a password. You agree to provide accurate, complete, and current information and to keep it up to date. You are responsible for activity under your account and for keeping your credentials secure; tell us promptly if you suspect unauthorised use. You may not impersonate others, transfer your account without our written consent, or operate multiple accounts to gain an unfair advantage. Organisational participants must designate an authorised representative.

Submissions

You are responsible for everything you submit and for ensuring you have the right to submit it. You agree to use the Platform only for lawful purposes. For most Challenges only encrypted or benchmark artifacts are uploaded during the run; a leading solution may be asked for its full source and documentation before any compensation is confirmed. You represent that your submission is your own work and does not infringe anyone's intellectual property or other rights.

Intellectual property

Unless a Challenge states otherwise, solutions you submit are licensed under the Apache License, Version 2.0, and we may publish winning solutions under that licence. You retain ownership of your work subject to that licence. You warrant that your submission does not infringe any third party's rights, and you agree to attribute any third-party material your solution relies on.

Compensation

Where a Challenge offers compensation, the amount and conditions are stated on its page. We determine the qualifying result based on the leaderboard and review by the platform's committee, and full documentation may be validated before payment. Compensation is paid in US Dollars through an authorised payment provider; direct payment may not be possible in all cases. You are solely responsible for any tax, social, or other obligations arising from compensation you receive, and we may disclose compensation information to authorities where required by law.

The Platform may link to or rely on third-party websites and services, including code repositories and container registries you point us to. We do not control and are not responsible for third-party content, terms, or privacy practices.

Disclaimers

The Platform and Challenges are provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including any warranty that the Platform will meet your needs, be uninterrupted, or be error-free.

Limitation of liability

To the fullest extent permitted by law, Fair Math will not be liable for any indirect, incidental, special, exemplary, punitive, or consequential damages, or for lost profits, revenue, data, or goodwill, arising from your use of the Platform or participation in a Challenge. Our total liability to you for any claim will not exceed the compensation, if any, we have paid you in connection with the matter giving rise to the claim. Nothing in these Terms excludes liability that cannot be excluded under applicable law.

Indemnification

You agree to indemnify and hold harmless Fair Math and its officers, employees, partners, and affiliates against any claims, losses, liabilities, and expenses (including reasonable legal fees) arising from your breach of these Terms or your misuse of the Platform.

Personal data

We take privacy seriously. Our handling of personal data is described in the Privacy Policy, and our use of cookies in the Cookie & Legal Notice.

Governing law

These Terms are governed by the laws of the State of Delaware and applicable US federal law, without regard to conflict-of-law rules. The state and federal courts located in Delaware have exclusive jurisdiction over any dispute arising from these Terms or the Platform.
