Terms of Service

1. Agreement

These Terms of Service (“Terms”) form a legally binding agreement between you and Infoscience Labs (“Infoscience,” “we,” “us”) operating the SenderSignal service (the “Service”). By creating an account or using the Service, you agree to these Terms.

2. The Service

SenderSignal is a deliverability and reputation monitoring platform that probes public blocklists, reputation feeds, and DNS records to alert you when your email-sending infrastructure is at risk. The Service does not send, proxy, throttle, or otherwise interfere with your email traffic.

3. Your account

You are responsible for keeping your credentials secure and for all activity under your account. You must be at least 18 years old to create an account. You must provide accurate billing information and notify us promptly of any changes.

4. Acceptable use

You agree not to:

• Use the Service to monitor domains or IPs you do not own or have written authorization to monitor.
• Reverse-engineer, decompile, or attempt to extract the source code of the Service.
• Use the Service to facilitate spam, phishing, or any unlawful activity.
• Probe, attack, or attempt to gain unauthorized access to the Service or its underlying infrastructure.
• Resell or sublicense the Service without written agreement.
• Exceed published rate limits or attempt to circumvent them.

5. Plans, fees, and billing

Paid plans are billed in advance on a monthly or annual cycle. Fees are non-refundable except where required by law. We may change pricing with at least 30 days' notice; changes apply at the start of the next billing cycle. Annual plans renew automatically unless cancelled before renewal.

Free plans are subject to fair-use limits and may be discontinued or rate-limited at our discretion to protect Service availability.

6. Service level

We target 99.99% monthly availability of the alerting pipeline. Enterprise customers receive a contractual SLA with credits if we miss our target. Detection latency targets (P50 8.3s, P99 30s) are measured across our edge fleet and are not guaranteed for any individual probe.

7. Customer data

You retain ownership of all data you provide. You grant us a limited license to process that data solely to operate the Service. We will treat your configuration, alert history, and usage data as confidential. Our handling of personal data is governed by our Privacy Policy.

8. Third-party services

The Service integrates with third-party platforms (Slack, PagerDuty, Microsoft Teams, etc.) at your direction. We are not responsible for the availability, accuracy, or behavior of those third-party services.

9. Intellectual property

Infoscience Labs retains all right, title, and interest in and to the Service, including all software, content, and trademarks. These Terms grant you a limited, non-exclusive, non-transferable license to use the Service during the term of your subscription.

10. Termination

You may cancel your subscription at any time from the dashboard. We may suspend or terminate your access for material breach of these Terms with reasonable notice (immediately for security or legal violations). Upon termination you may export your data for 30 days; after that we may delete it.

11. Warranty disclaimers

The Service is provided “as is” and “as available” without warranty of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will detect every possible listing or that it will be uninterrupted or error-free. While we operate at high reliability, you should not rely on the Service as the sole guard for your sending infrastructure in life-safety contexts.

12. Limitation of liability

To the maximum extent permitted by law, our aggregate liability arising out of or related to these Terms or the Service will not exceed the amount you paid us in the 12 months preceding the event giving rise to the claim. We will not be liable for any indirect, incidental, consequential, special, or punitive damages, or for lost profits, lost revenue, or lost data.

13. Indemnification

You agree to indemnify and hold harmless Infoscience Labs and its affiliates against claims arising out of your misuse of the Service, your violation of these Terms, or your violation of any third-party rights.

14. Governing law

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws principles. The exclusive venue for any dispute is the state and federal courts located in Wilmington, Delaware.

15. Changes

We may update these Terms from time to time. Material changes will be announced on this page and notified to active customers by email at least 14 days before they take effect. Continued use of the Service after the effective date constitutes acceptance.
