Terms of Service
Last updated: 12 August 2026
1. Agreement
These Terms of Service ("Terms") govern access to and use of Walters Sentinal (the "Service"), operated from walterssentinel.com and app.walterssentinel.com. By creating an account or paying for a subscription, you agree to these Terms. If you don't agree, don't use the Service.
The Service is intended for business and commercial use — monitoring infrastructure you operate or are authorised to monitor on behalf of a business, agency, or client. By subscribing, you confirm you're entering into this agreement in the course of business, not as a consumer purchasing for personal use.
2. The Service
Walters Sentinal monitors websites, APIs, SSL certificates, domain expiry, DNS records, email authentication records, and blacklist status that you configure, and alerts you when a check fails. The Service reports on the availability of the things you monitor — it does not guarantee the uptime of your website, API, or any third-party infrastructure, and monitoring something does not make us responsible for its performance.
3. Accounts
- You must provide an accurate email address you control — account access and all security codes are sent there.
- You're responsible for anything that happens under your account, including team members you invite.
- You must not share login credentials, attempt to bypass verification, or access another account without authorisation.
- We may lock, suspend, or terminate accounts for breach of these Terms, abuse, non-payment, or misuse of the Service — see Section 8.
4. Acceptable use
You agree not to use the Service to monitor infrastructure you're not authorised to monitor, to facilitate illegal activity, or to probe, scan, or send unusual load at targets in a way that could reasonably be mistaken for an attack. We reserve the right to review monitors added to any account, and to remove monitors that appear to target unsafe, unauthorised, or unlawful environments, in line with our internal moderation process.
5. Fees, billing, and cancellation
- Plans are billed monthly in advance via Stripe. Prices are shown on the pricing page and may change; if we change your plan's price, we'll show it on the site — continued use after a price change means you accept the new price from your next billing cycle.
- All fees are non-refundable. This includes partial months, unused time after cancellation, and downgrades. Cancelling stops future billing; it does not refund the current period, which you retain access to until it ends.
- Nothing in this section limits any right you have under law that cannot lawfully be excluded by these Terms.
- We may suspend access for non-payment.
6. Enterprise and White-label/MSP plans
These plans can be purchased directly through the Service without needing to contact us first. White-label/MSP customers may present the Service's monitoring and status-page features under their own branding to their own clients, but this licence doesn't transfer ownership of the underlying platform, code, or Walters Sentinal branding.
7. Service availability
We aim to keep the Service running reliably but don't guarantee uninterrupted availability. We may perform maintenance, and we may modify or discontinue features with reasonable notice where practical.
Raw monitor check history and alerts are automatically deleted after 90 days to keep the Service running efficiently — this doesn't affect your monitors themselves or their current status, only historical logs. See our Privacy Policy for the full data retention schedule, including what we keep for longer (e.g. billing records, as required by law).
8. Suspension, locking, and termination
We may lock an account automatically after repeated failed sign-in attempts, for your own security. Administrators may lock, suspend, or terminate accounts for breach of these Terms, suspected fraud, abuse of the Service, or monitoring of unsafe/unauthorised targets. Where we take this kind of action, we'll email you the reason. You may appeal by contacting contact@walterssentinel.com.
9. Limitation of liability
The Service is provided "as is" and "as available". To the maximum extent permitted by law, Walters Sentinal is not liable for indirect, incidental, or consequential damages, or for losses arising from downtime of infrastructure you monitor (including our failure to detect or alert on an outage). Our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim arose. Nothing in these Terms excludes liability that cannot lawfully be excluded, such as liability for death or personal injury caused by negligence, or fraud.
10. Indemnity
You agree to indemnify Walters Sentinal against claims, losses, or damages arising from your breach of these Terms or misuse of the Service, including monitoring targets you weren't authorised to monitor.
11. Governing law
These Terms are governed by the laws of England and Wales, and any dispute is subject to the exclusive jurisdiction of the courts of England and Wales.
12. Changes to these Terms
We may update these Terms from time to time. Material changes will be reflected here with an updated date. Continued use of the Service after a change means you accept the updated Terms.
