Sendline provides software that lets your business operate an iMessage support agent. You give us your knowledge base and configuration; we run the agent, route messages, and bill you. Either of us can end this arrangement at any time, subject to the rest of these terms.

You must be at least 18 and have authority to bind your business. Keep your credentials confidential. You're responsible for everything that happens in your workspace, including actions by team members you invite. Tell us promptly if you suspect unauthorized access.

Don't use Sendline to break the law, harass people, send spam or unsolicited marketing messages, impersonate someone you're not, distribute malware, scrape or reverse-engineer the service, infringe anyone's intellectual property, or operate in industries explicitly restricted by Apple's iMessage policies (gambling, adult content, regulated pharmaceuticals).

You're responsible for obtaining the consent your local law requires before sending automated text messages to your customers. In the U.S. that means TCPA compliance.

Anything you upload to Sendline — your knowledge base, configurations, agent prompts, and the conversation data routed through your workspace — stays yours. You grant us a limited license to host, process, and transmit it strictly to deliver the service. We don't use it to train AI models, and we don't share it with anyone except the sub-processors listed in our Privacy Policy.

The agent generates replies based on your knowledge base, your role prompt, and the customer's message. Outputs can be wrong, incomplete, or unexpected — particularly for edge cases, novel questions, or topics your KB doesn't cover. You're responsible for reviewing the agent's behavior in your workspace, setting appropriate guardrails, and intervening when needed. We provide tools to make this easier (citations, escalation rules, take-over) but we don't guarantee the accuracy of any specific reply.

Subscriptions are billed monthly to the card on file. The first charge is processed when you complete checkout; subsequent charges occur on the same calendar day each month. Usage above the included conversation cap is billed in arrears. You can change or cancel your plan at any time in Settings; cancellation takes effect at the end of the current billing period.

All fees are exclusive of taxes. We will charge applicable sales or VAT where required. Failed payments are retried over 14 days; sustained non-payment results in workspace suspension.

You can delete your workspace at any time, for any reason, from Settings → Danger zone. We may suspend or terminate your account if you violate these terms or if your use poses a security risk to the service or to other customers. We will give you 14 days' notice of termination for non-emergency reasons, and we will let you export your conversation data before deletion takes effect.

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. We don't warrant that the service will be uninterrupted, error-free, or that the agent will produce specific results.

Neither party is liable for indirect, incidental, consequential, or punitive damages, including lost profits or revenue. Our total aggregate liability arising out of or relating to these terms is capped at the greater of (a) the fees you paid us in the 12 months preceding the claim, or (b) one hundred U.S. dollars ($100). These limits apply to the maximum extent permitted by applicable law.

You agree to indemnify Sendline against third-party claims arising from your knowledge base content, your agent's outputs, or your violation of these terms or any law. We agree to indemnify you against third-party claims that the service itself infringes a U.S. patent, copyright, or trademark, subject to standard exceptions.

These terms are governed by the laws of the State of California, without regard to conflict-of-law rules. Any dispute will be resolved in the state or federal courts located in San Francisco County, and both parties consent to that jurisdiction.

We may update these terms as the product and the law evolve. Material changes will be announced by email at least 30 days before they take effect. Continued use after that date means you accept the updated terms. If you don't, you can cancel your subscription before the changes take effect.
