Terms of service

1 · THE SERVICE

By creating an account or using STACK, you agree to these terms. STACK provides infrastructure for controlling and recording how AI agents use connected services. You remain responsible for your agents, their instructions and the access and data you give them. Some features depend on third-party services or run inside STACK. Published measurements describe the version and environment tested; they are not a service-level commitment unless a signed agreement says otherwise.

2 · ACCOUNT & ACCEPTABLE USE

You must have legal capacity to agree to these terms. If you use STACK for an organisation, you confirm that you can bind it. You are responsible for keeping your email, sessions and API keys secure and for activity under your account.

Do not use STACK for illegal, fraudulent, abusive, or rights-infringing activity. Do not connect a credential you are not authorised to use. Do not send spam, distribute malware, harvest personal data unlawfully, bypass usage controls, or attack a system without permission. Good-faith testing is authorised only within the rules of the attack playground. Report other security issues to security@getstack.run.

3 · PLANS, BILLING & REFUNDS

Current prices, allowances and usage rates are published on the pricing page. Paid plans are billed monthly in advance through Stripe and renew until cancelled. Cancellation takes effect at the end of the current billing period. You can cancel in Console Settings or by emailing hello@getstack.run. Usage above an included allowance can be charged to your wallet. A paid operation can be refused when the wallet balance is too low, and rate limits or feature limits can still apply.

An unused wallet top-up can be refunded in full within 30 days if the wallet still holds the full top-up amount. The self-service flow does not issue partial refunds. Charges for completed usage and paid skill invocations are not refundable through that flow. Any withdrawal, cancellation or refund right that cannot lawfully be excluded still applies.

4 · YOUR DATA & INTELLECTUAL PROPERTY

You keep your rights in the data and content you submit. You give STACK the rights needed to host, process, transmit, secure, back up and display that material to operate, protect and improve the service. STACK may create and use aggregated or de-identified statistics that do not identify you or expose your content. The privacy notice explains how personal data is handled. STACK retains its rights in the platform, brand, design, documentation and proprietary code. Published SDK and CLI code remains under its stated licence.

5 · THIRD-PARTY SERVICES

STACK can connect to services that you select. Their terms, availability, prices, data locations, and API behavior remain their responsibility. You must have permission to connect each account and credential. A third-party outage or contract change can stop the related STACK integration. STACK is not responsible for a third party outside the control that law or a signed agreement assigns to STACK.

6 · AVAILABILITY, WARRANTIES & LIABILITY

Features marked beta or preview can change, fail or be removed. They have no service-level commitment unless a signed agreement says otherwise. To the maximum extent permitted by law, STACK is provided as is and as available. STACK does not promise that detectors will find every harmful action or that the service will be uninterrupted or error-free. Compliance material describes the product; it is not legal advice or a conformity assessment.

To the maximum extent permitted by law, STACK's aggregate liability for claims relating to the service is capped at the greater of the fees you paid in the twelve months before the event or €100. STACK is not liable for indirect, consequential, incidental, special, or punitive damages, including lost profit, lost data, or business interruption. These limits do not apply where law does not permit them, including mandatory consumer rights and liability that cannot lawfully be excluded.

If you use STACK for a business, you will defend and indemnify STACK against third-party claims caused by your unlawful use, your agents, credentials you connect without authority or rights you infringe. STACK will give reasonable notice and let you control the defence with counsel reasonably acceptable to STACK.

7 · SUSPENSION, TERMINATION & DELETION

STACK can suspend access when an account creates a material security, legal, fraud, or service risk. STACK will give notice where practicable and lawful. You can delete your account from Console Settings. Deletion ends access and starts the erasure process described in the privacy notice. Export anything you need first. Some provider backups and records required by law can remain until their applicable retention period ends.

8 · CHANGES, LAW & CONTACT

STACK may update these terms when the service or law changes. The date at the top will change, and material changes will be announced before they take effect where required. Swedish law governs and courts in Stockholm have jurisdiction, subject to any mandatory rights that apply to you. If one clause cannot be enforced, the rest remains in effect. These terms, the privacy notice and any signed order form make up the agreement for the service. Questions go to hello@getstack.run. STACK is operated from Stockholm, Sweden.
