Terms of Service

01The service

Sill is agent-governance infrastructure that sits in front of your existing commerce stack. It identifies and logs AI-agent traffic (Discovery), and, in transactional mode, evaluates signed mandates against your policy and authorizes the resulting action through your payment processor while producing a signed, exportable audit record.

Sill is not a payment processor and does not custody funds. Where a payment is authorized, your processor (for example, Stripe) holds the card data, authorizes the charge, settles to your account, and pays out. Sill issues the signed authorization and the audit record.

02Eligibility and accounts

You must be able to form a binding contract to use Sill. You are responsible for your account, for keeping your sign-in secure, and for activity under your account. Sign-in uses a magic link sent to your email; keep access to that mailbox secure.

03Acceptable use

• —Do not use the service unlawfully, or to infringe the rights of others.
• —Do not attempt to breach, probe, or circumvent security or multi-tenant isolation, except under a written authorization from us.
• —Do not interfere with or disrupt the integrity or performance of the service.
• —Do not misrepresent identity or provenance in mandates, agent cards, or audit data.

04Your data and responsibilities

You are responsible for your own compliance obligations to your end customers and agents, including providing your own privacy notices and obtaining any required consents. With respect to personal data Sill processes on your behalf, you are the controller and Sill is the processor; that relationship is governed by our Data Processing Addendum, which forms part of these Terms.

As between you and Sill, you retain all rights in your data. You grant Sill the rights necessary to operate the service for you, including producing and storing signed audit records.

05Third-party services

The service interoperates with third-party providers you choose to connect (for example, Stripe and Shopify). Your use of those services is governed by their own terms, and we are not responsible for them.

06Fees

Discovery mode is provided at no charge. Fees for any paid tiers or transactional features, if and when offered, will be set out in an order form or our then-current published pricing, and we will make applicable fees clear before you incur them.

07Intellectual property

Sill and its underlying software, design, and documentation are owned by Sill Labs Inc. and its licensors. These Terms grant you a limited, non-exclusive, non-transferable right to use the service; they do not transfer any ownership to you.

08Disclaimers

The service is provided “as is” and “as available.” To the maximum extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. Sill provides governance, evaluation, and evidence tooling; it does not guarantee any particular commercial, fraud, or compliance outcome.

09Limitation of liability

To the maximum extent permitted by law, neither party is liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits or revenues. Our aggregate liability arising out of or relating to the service is limited to the greater of (a) the fees you paid to Sill in the twelve months before the event giving rise to the liability and (b) US$100. Nothing limits liability that cannot be limited under applicable law.

10Indemnification

You will defend and indemnify Sill Labs Inc. against third-party claims arising from your unlawful use of the service or your breach of these Terms, except to the extent caused by Sill.

11Term and termination

You may stop using the service at any time. Either party may terminate for material breach that remains uncured after notice. On termination, your right to use the service ends; provisions that by their nature should survive (including ownership, disclaimers, and limitation of liability) survive. Data handling on termination is governed by the Privacy Policy and the DPA.

12Governing law and disputes

These Terms are governed by the laws of the State of Delaware, USA, without regard to conflict-of-laws rules, and the exclusive venue for disputes is the state and federal courts located in Delaware, USA.

13General

Neither party is liable for delay or failure caused by events beyond its reasonable control. You may not assign these Terms without our consent; we may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets. If any provision is held unenforceable, the remainder stays in effect. These Terms, together with the Privacy Policy, the DPA, and any order form, are the entire agreement on their subject and supersede prior understandings.

14Changes and contact

We may update these Terms; we will revise the effective date and, for material changes, provide notice where required. Questions: [email protected].
