Privacy Policy
Last updated: 12 August 2026
1. Who we are
Walters Sentinal ("we", "us") operates walterssentinel.com and app.walterssentinel.com. Contact: contact@walterssentinel.com.
2. What we collect
| Data | Why |
|---|---|
| Account email, hashed password | To create and secure your account |
| Name (individual accounts) or company name and company/VAT registration number (business accounts) | To identify who holds the account and issue accurate invoices |
| One-time sign-in codes (sent, not stored in readable form) | Email-based two-factor verification on every sign-in |
| URLs/domains you add as monitors | To perform the monitoring you've configured |
| Billing details (via Stripe — we never see full card numbers) | To process your subscription payment |
| IP address, basic request logs | Security, abuse prevention, debugging |
| Support/contact emails you send us | To respond to you |
3. Legal basis (UK GDPR)
We process account and billing data under contract necessity (to provide the Service you've signed up for), and security/abuse-prevention data under legitimate interest. Where we send you optional communications, we rely on your consent.
4. How we use your data
- To run your monitors and send you the alerts you've configured.
- To verify your identity on sign-in (one-time email codes).
- To process payments and send billing confirmations.
- To respond to support requests.
- To detect and prevent abuse — including reviewing monitors that appear to target unauthorised or unsafe infrastructure.
We do not sell your data, and we don't use it for advertising.
5. Who we share it with
- Stripe — processes payments. We never store full card numbers.
- Titan Mail (123-reg) — sends transactional email (verification codes, alerts, notifications) and, for admin purposes, receives contact-form email.
- We don't share your data with anyone else except where required by law.
6. International transfers
Stripe may process data outside the UK, operating under its own standard contractual safeguards (Stripe publishes its own data protection terms covering international transfers). 123-reg/Titan Mail is a UK-based provider.
7. How long we keep data
We keep account data for as long as your account is active, and for a reasonable period after closure for legal, billing, and dispute-resolution purposes. Different data has different retention periods:
| Data | Retention |
|---|---|
| Raw monitor check history and alerts | Automatically deleted after 90 days. Your monitors and their current status are unaffected — this only prunes the historical log. |
| One-time verification/reset codes | Expire within minutes; deleted outright within 24 hours regardless of use. |
| Payment and billing records | Retained for the life of the account and beyond as required by UK tax law (a minimum of 6 years) — never auto-deleted. |
| Admin action logs (locks, suspensions, moderation) | Retained for the life of the account for accountability and dispute resolution. |
| Account details, monitors, support emails | Retained while your account is active, and for a reasonable period after closure. |
8. Your rights
Under UK GDPR you can ask us to: give you a copy of your data, correct it, delete it, restrict how we use it, or provide it in a portable format. Email contact@walterssentinel.com to exercise any of these. You can also complain to the UK Information Commissioner's Office (ico.org.uk) if you think we've mishandled your data.
9. Cookies & local storage
We use a session cookie to keep you signed in, and browser local storage to remember your theme preference. We don't use third-party advertising or tracking cookies.
10. Children
The Service is intended for business use by adults. We don't knowingly collect data from children.
11. Changes to this policy
We may update this policy from time to time; material changes will be reflected here with an updated date.
