1. Introduction
MarCas Code ("we", "us", "our") operates the LatencyRadar service (the "Service").
This Privacy Policy explains what personal data we collect, how we use it, and your rights under applicable data protection laws, including the General Data Protection Regulation (GDPR).
If you have questions, contact: support@latencyradar.com
2. What Data We Collect
2.1 Test Data
When you run a latency test, we store:
- The target URL
- HTTP method
- Custom headers (if provided)
- Timing metrics (DNS, TLS, connect, TTFB, download, total)
- Status codes and error types
- Test mode (preview or full)
- Test timestamps
We do not store:
- Response bodies
- API response content
- Cookies returned by the target server
You are responsible for ensuring you are authorized to test the endpoint.
2.2 Technical & Usage Data
When you use the Service, we may collect:
- IP address
- Browser type and version
- Device type
- Operating system
- Referrer information
- Interaction events (see below)
This data is used to maintain service security and stability.
2.3 Product Analytics (PostHog and Google Analytics)
We use PostHog to understand how the Service is used and to improve functionality.
We also use Google Analytics to count visits and see which pages people arrive on. It loads only after you accept analytics in the cookie banner, and it sets its own cookies in your browser.
Events we track may include:
- Quick check started
- Quick check completed
- Deeper check started
- Rate limit triggered
- Newsletter subscription, confirmation, and unsubscription
We do not send:
- Full target URLs with sensitive query parameters
- Authorization headers
- Response data
- API keys
PostHog may process:
- IP address (may be truncated or anonymized)
- Device and session information
- Event metadata related to Service usage
Analytics are used strictly for product improvement and service monitoring.
2.4 Requested Emails
If you ask us to email a quick-check report, we use the address only to deliver that requested transactional message.
- The email is sent through Resend
- We store a one-way hash of the address in our delivery log for duplicate prevention and abuse control
- We do not add the address to a marketing list
The message may contain the non-sensitive test target with credentials, query parameters, and URL fragments removed.
2.5 Newsletter (optional)
If you subscribe to our monthly latency report, we store your email address so we can send it to you. This is separate from the requested transactional emails above and happens only when you ask for it.
We store:
- Your email address
- When you subscribed and when you confirmed (double opt-in: nothing is sent until you confirm via the link in the confirmation email)
- The page and form where you subscribed, so we know which content is useful
- IP address and browser information from the signup request, for abuse prevention
Legal basis, retention, and withdrawal:
- Legal basis: your consent (GDPR Art. 6(1)(a))
- Unconfirmed addresses are deleted automatically after the confirmation link expires (14 days)
- We keep the address until you unsubscribe; every email contains a one-click unsubscribe link
- You can also withdraw consent anytime via support@latencyradar.com
The newsletter list is stored on our own infrastructure. Emails are delivered through Resend. We never share or sell the list.
3. Legal Basis for Processing (GDPR)
We process personal data based on:
- Legitimate interest (service functionality, security, analytics)
- Consent (newsletter subscription; you can withdraw it anytime via the unsubscribe link)
- Legal obligations (if required by law)
4. Data Retention
We retain test data for operational and diagnostic purposes.
Retention periods may vary but are limited to what is reasonably necessary to:
- Provide the Service
- Prevent abuse
- Improve system performance
Test data is retained for up to 30 days unless a shorter retention period is required for operational or legal reasons.
We may delete test data periodically.
Analytics data retention is managed through PostHog according to configured retention policies.
We keep Google Analytics data for the retention period configured on that property.
5. Data Sharing
We may share data with:
- PostHog (analytics)
- Google (Google Analytics)
- Resend (transactional and newsletter email delivery)
- Hosting providers (VPS infrastructure)
We do not sell personal data.
We do not share data for advertising purposes.
6. International Data Transfers
Some service providers (such as PostHog Cloud, Google Analytics, or Resend) may process data outside the European Economic Area (EEA).
Where applicable, appropriate safeguards are in place in accordance with GDPR.
7. Security Measures
We implement reasonable technical and organizational measures to protect data, including:
- Rate limiting
- Private IP blocking
- Concurrency caps
- Secure HTTPS encryption
- Access control to internal systems
However, no system can guarantee absolute security.
8. Your Rights (GDPR)
If you are located in the EU, you have the right to:
- Access your personal data
- Request correction
- Request deletion
- Restrict processing
- Object to processing
- Lodge a complaint with a supervisory authority
To exercise your rights, contact: support@latencyradar.com
9. Cookies
The Service may use essential cookies required for functionality and security.
We set analytics cookies only after you accept them in the consent banner.
We do not use advertising cookies.
