Privacy Policy

Last updated: September 23, 2026

Sentinel is operated by FixFlex LTD (company no. 08944523, registered office: 170 Connell Crescent, London, W5 3BP, United Kingdom), which is the data controller for the personal data described in this policy.

1. Data Collection & The Log Sanitizer

Sentinel is designed with privacy as a core tenet. We collect minimal data necessary for the "Autopilot" functionality.

  • Sanitized Logs: Before any server log leaves your Drone, it passes through our local "Log Sanitizer". This process removes IP addresses, email addresses, and recognized sensitive patterns.
  • Error Patterns: We collect abstract error signatures (e.g., "Connection refused on port 5432") to build the Knowledge Book.
  • System Telemetry: CPU usage, RAM usage, and service status are monitored to trigger health checks.

2. Use of Data

We use the collected data for the following purposes:

  • To identify and diagnose server issues across the Sentinel network.
  • To verify the success rate of automated fixes.
  • To provide you with analytics via the Queen Dashboard.
  • To process payments and manage your subscription (via Stripe).

3. Third-Party Services

Stripe:We use Stripe for payment processing. We do not store your credit card information on our servers. Stripe's use of your data is governed by their Privacy Policy.

Anthropic (Claude): Optional AI features in Sentinel Enterprise (AI Healer, AI Chat) call the Claude API using an API key that you provide. Data sent this way is processed under your own agreement with Anthropic. Our central service (Queen) may also use Claude, or a self-hosted model, to analyse the abstract error patterns described in section 1.

Google Analytics: Used on this marketing website only, and only if you accept analytics cookies (see section 4). It is not active within the Drone agent itself.

Some of these providers are based outside the UK, for example in the United States. Where personal data is transferred internationally, it is protected by the UK's adequacy regulations (such as the UK–US Data Bridge) or by appropriate safeguards such as the UK International Data Transfer Agreement, as provided by the relevant provider.

4. Cookies

This website only sets analytics cookies if you click "Accept" on our cookie banner. If you decline, or make no choice, Google Analytics is not loaded and no analytics cookies are set.

  • _ga (Google Analytics) — distinguishes unique visitors, 2 years, optional (consent).
  • _ga_<ID> (Google Analytics) — keeps session state, 2 years, optional (consent).

Your choice is stored in your browser's local storage (sentinel_cookie_consent) and is not sent to us. You can change it at any time via "Cookie settings" in the site footer; declining removes the Google Analytics cookies from this site.

5. Blog Comments

If you comment on a blog post, the name you enter and your comment are stored by our blog service and shown publicly next to the post. Your comment is sent to an AI model through OpenRouter (United States), which routes it to a model provider (currently DeepSeek), to check it for spam and to generate the reply marked "Sentinel AI". The legal basis is our legitimate interest in running a moderated blog (Article 6(1)(f) UK GDPR). Comments are kept while the post is published; you can ask us to remove yours at any time.

6. Data Retention

Raw logs (even sanitized ones) are retained only as long as necessary to generate a "Solution Pattern". Once a pattern is verified in the Knowledge Book, the raw source logs are typically discarded or aggregated into anonymous statistics.

7. Your Rights (UK GDPR)

You have the right to access, correct or erase your personal data, to restrict or object to certain processing, to data portability where applicable, and to withdraw consent at any time. You can also lodge a complaint with the Information Commissioner's Office (ico.org.uk).
