Terms of Service

Last updated: September 21, 2026

Welcome to Sumus. These terms apply to the Sumus website, AI agents, and related services (the “Service”). By using the Service, you agree to these terms. Our Privacy Policy explains how we handle personal information.

1. Your account and eligibility

You must be at least 18 years old and legally able to enter into this agreement. If you use the Service for an organization, you must be authorized to accept these terms on its behalf. Provide accurate account information and protect access to your account and connected services.

2. Agents and connected services

Sumus helps you complete tasks and collaborate through AI agents. You authorize the Service to process content, use tools, and work with connected services according to your instructions, settings, and the permissions you grant, including autonomous, scheduled, and unattended tasks you configure. When you connect a local computer, agents can use the files, tools, and accounts you authorize.

You must have the right to use the content and services you provide. You are responsible for actions within your authorization and any resulting charges or commitments to third parties. AI outputs may contain errors; review them before relying on them or taking significant action.

Third-party services you connect have their own terms. You are responsible for managing those accounts and paying their charges. Changes, restrictions, or interruptions to those services may affect related features; Sumus does not guarantee their availability.

3. Content and intellectual property

You retain your rights in your inputs. As between you and Sumus, you may use the outputs generated for you, and we assign to you any rights we may hold in those outputs to the extent permitted by law. This does not transfer rights in third-party materials or guarantee that outputs are unique.

You allow us to store, process, transmit, and display your content as needed to provide the Service, including completing tasks, enabling collaboration, and providing support. Rights in the Service's software, design, and branding remain with us or the relevant rights holders.

4. Subscriptions, credits, and refunds

Prices, features, allowances, and billing periods are shown on Pricing and when you purchase. Paid plans automatically renew for the selected monthly or annual period until canceled. We will notify you in advance of changes to renewal prices.

Extra credits are a separate monthly subscription that renews automatically. Plan and extra credits are issued monthly, do not roll over, and cannot be redeemed for cash. Cloud agents consume credits based on usage. Local agents currently do not consume Sumus credits; connected services may charge separately.

Credits are consumed based on Service usage, regardless of whether a task succeeds or you are satisfied with its results. A given number of credits does not guarantee a fixed quantity or quality of outputs.

Manage subscriptions in Settings → Plan & credits. Plan cancellation takes effect at the end of the paid period. Extra-credit downgrades and cancellations take effect at the next monthly cycle. Charges and timing for upgrades and other plan changes are shown when you make the change. Contact support if you need help.

Subscription and credit payments are generally non-refundable, except where required by applicable law. For duplicate charges or verified platform faults, we will address refunds or credit returns based on the actual impact. We may consider other exceptional refund requests at our discretion. Cancellation does not automatically result in a refund. Send refund requests to support@sumus.im.

5. Acceptable use

Do not use the Service for unlawful activity, fraud, infringement, unauthorized data access, or other activity that harms others' rights. Do not distribute malware, disrupt the Service, or bypass access controls, payment requirements, or usage limits.

6. Service changes and termination

We may update Service features. Unless separately agreed in writing, feature descriptions do not guarantee continued availability or service levels; purchased entitlements remain subject to the terms agreed at purchase. We may restrict or suspend access for violations of these terms, nonpayment, or use that disrupts the Service, with notice where practicable.

You may stop using the Service at any time or contact support to request account closure. Before closing an account, cancel subscriptions you no longer need and save important content. Stopping use does not itself cancel a subscription.

7. Service responsibility

To the extent permitted by applicable law, the Service is provided as is and as available, without a guarantee of uninterrupted operation or fully accurate outputs. Sumus is not liable for indirect or consequential losses arising from use of or inability to use the Service.

To the extent permitted by applicable law, Sumus's aggregate liability arising from these terms or the Service will not exceed the total fees you actually paid to Sumus during the three months before the event giving rise to the claim. These limitations do not apply to fraud by Sumus, death or personal injury caused by Sumus's negligence, or liability that applicable law does not allow us to limit or exclude.

If content you have no right to use, your infringement of others' rights, or your violation of these terms causes a third-party claim against Sumus, you must compensate Sumus for resulting losses and reasonable legal and handling costs to the extent you are legally responsible. This excludes any portion caused by Sumus's own fault.

8. Updates and contact

We will publish updates to these terms here and revise the date. We will notify you of material changes as required by applicable law. Continuing to use the Service means you accept the terms in effect.
