Privacy at dcyfr.tech

What this page covers

This notice describes what dcyfr.tech collects, and who processes it on our behalf. It sits alongside the DCYFR Labs privacy policy, which governs the wider estate.

What we collect

• Request logs — IP address, user agent, and requested path, recorded by our host for security and debugging.
• Aggregate analytics — page views and performance timings, with no cookies and no per-person identifier.
• Error reports — the stack trace and browser context when something breaks.

What we do not do

• No advertising, retargeting, or data sales.
• No cross-site tracking and no behavioural profiles.
• No accounts, and no marketing email from this site.

Session recording (Sentry Replay)

We sample roughly 1% of sessions, and record the session around an error when one occurs, so we can reproduce faults we cannot otherwise see.

Recordings are masked at capture: text content and media are replaced before the recording leaves your browser, so what we receive is layout and interaction timing, not the words on your screen. Recordings are stored by Sentry and deleted on their retention schedule.

To opt out entirely, block sentry.io in your browser or use an extension that blocks error-monitoring scripts. The site works without it.

If you are in the EEA, the UK, or a US state with a comprehensive privacy law, you can ask us for a copy of your data, ask us to correct or delete it, or object to processing.
