Cookie Policy

This Cookie Policy explains how Sentinel Edge Networks LTD ("Sentinel", "we", "us") uses cookies and similar tracking technologies on sntlhq.com and any associated subdomains ("the Website"). This policy complies with the EU ePrivacy Directive, the General Data Protection Regulation (GDPR), and applicable UK law.

1. What Are Cookies?

Cookies are small text files placed on your device when you visit a website. Similar technologies include browser local storage, session storage, and JavaScript-based signals used for security purposes. We use a minimal set of these technologies — only what is strictly necessary to operate the platform securely.

2. Storage We Use

2.1 Strictly Necessary (localStorage)

We use browser localStorage (not traditional cookies) to keep you logged in and remember your preferences. This does not require consent under the ePrivacy Directive as it is essential to the service you requested.

2.2 Security & Fraud Prevention

We use proprietary security SDKs on our signup, login, contact, and dashboard pages. These SDKs collect network-layer signals (IP address, connection type, VPN/proxy status) and device-level signals (browser fingerprint, tampering detection, bot detection) to protect our platform from bot abuse, account takeover, antidetect browsers, and fraudulent signups.

This processing is based on our Legitimate Interest under GDPR Article 6(1)(f) to protect the platform and its users from fraud, abuse, and security threats. These SDKs do not set persistent cookies. They use in-memory session data and device signals for real-time threat assessment only.

We also check passwords against the Have I Been Pwned breach database during signup and password reset. Only a partial hash of the password is sent (k-anonymity) — your actual password is never transmitted.

We offer optional 3D Face Login powered by FaceTec. If you enable this feature, your device camera captures a 3D liveness scan to verify you are a real person. The face scan data is processed by FaceTec's servers for liveness verification only — we do not store facial images or biometric data on our servers. Your device identity is linked to your account to enable face-based authentication.

If you wish to object to this processing under GDPR Article 21, please contact us at [email protected]. Note that objecting may prevent you from using certain features of the platform.

2.3 Performance & Analytics

We do not currently use third-party analytics (e.g. Google Analytics). If we introduce analytics in the future, we will update this policy and request your explicit consent before activating them.

2.4 Marketing & Advertising

We do not use any marketing, retargeting, or advertising cookies or trackers on this Website.

3. Third-Party Services

The following third-party services are integrated and may process data from your device:

4. How to Control Storage

4.1 Our Cookie Banner

When you first visit the Website, a consent banner is shown. You can accept or decline non-essential storage at that time. To update your preferences, clear your browser's localStorage for sntlhq.com and reload the page.

4.2 Browser Settings

You can clear localStorage and cookies via your browser's developer tools or settings. Note that clearing sentinel_token will log you out of the dashboard. Instructions for major browsers:

• Google Chrome
• Mozilla Firefox
• Apple Safari
• Microsoft Edge

5. International Transfers

Some third-party providers (Resend, Railway, Google) may process data outside the UK and European Economic Area (EEA). Where this occurs, we ensure appropriate safeguards are in place, including Standard Contractual Clauses (SCCs), UK International Data Transfer Agreements, or adequacy decisions.

6. Your GDPR Rights

As an EU/EEA resident, you have the following rights regarding your personal data:

• Right of Access — request a copy of data we hold about you.
• Right to Rectification — request correction of inaccurate data.
• Right to Erasure — request deletion of your data ("right to be forgotten").
• Right to Restrict Processing — request that we limit how we use your data.
• Right to Object — object to processing based on legitimate interests.
