Cfix is an application error tracking and monitoring platform that captures JavaScript errors, stack traces, and performance metrics from web applications. It helps developers identify and fix bugs in production. Error tracking can generally rely on legitimate interest for application security and stability. However, if error logs include user session data or personal information, appropriate safeguards are needed. Data is processed in the US.
Cfix is an application error tracking and monitoring tool that helps development teams detect, diagnose, and resolve JavaScript errors and performance issues in production web applications. It captures error events, stack traces, browser and environment context, and optionally user session identifiers to help developers reproduce and fix bugs. Cfix is typically integrated into web applications via a JavaScript snippet included in the site''s code.
Cfix collects JavaScript error messages and stack traces, browser type and version, operating system, screen resolution, page URL at the time of error, timestamp, and session identifiers. If user context is configured, it may also collect user identifiers or email addresses to link errors to specific users. IP addresses are typically logged as part of server-side error reporting.
Basic error tracking without user identifiers can generally rely on legitimate interest under GDPR Article 6(1)(f). The processing is necessary for application security and stability, minimally intrusive, and serves a clear technical purpose. When Cfix is configured to link errors to user identifiers or email addresses, the processing becomes more privacy-sensitive and may require consent or a more carefully documented legitimate interest test.

If Cfix sets persistent cookies for session tracking, ePrivacy consent is required before those cookies are set. Error tracking that operates purely through server-side logging without cookies on the user''s device does not require cookie consent. Review Cfix''s cookie behaviour and configure it to minimise unnecessary cookie use.
Cfix is a US company. All error and monitoring data is processed on US infrastructure. Standard Contractual Clauses apply. Sign a DPA with Cfix and document the US transfer in your RoPA.
Document your legitimate interest balancing test for error monitoring. Configure Cfix to minimise personal data in error reports (mask or omit user identifiers where not needed for debugging). Sign a DPA with Cfix. Update your privacy policy. If Cfix sets persistent cookies, obtain ePrivacy consent. Document the US transfer in your RoPA.
Websites using Cfix must obtain user consent under GDPR regulations.
DPIA considerations
A DPIA is generally not required for basic error tracking. It becomes advisable when error logs systematically capture user session identifiers or personal data, particularly if user-linked error reports are retained for extended periods or used for profiling.
Sample consent text
We use Cfix to monitor application errors and improve site stability. Cfix may collect technical information including error logs and session identifiers. Data is processed in the United States. This processing relies on our legitimate interest in maintaining a functioning website.

Cfix is an essential service, but transparency matters. Manage all your consent with FlowConsent.
Cfix collects JavaScript error messages and stack traces, browser type and version, OS, screen resolution, page URL at the time of error, timestamp, and session identifiers. If configured, it may also collect user identifiers or email addresses to link errors to specific users.
Not necessarily. Basic error tracking without user identifiers can rely on legitimate interest without a consent banner. If Cfix sets persistent cookies for session tracking, ePrivacy consent is required for those cookies. Error tracking should be disclosed in your privacy policy regardless.
Legitimate interest (Art. 6(1)(f)) for anonymous or pseudonymous error tracking strictly necessary for application security and stability. Consent (Art. 6(1)(a)) if Cfix sets persistent tracking cookies or links errors to identifiable user accounts.
Yes. Cfix is a US company processing all error and monitoring data on US infrastructure. Standard Contractual Clauses apply. Sign a DPA with Cfix and document the US transfer in your RoPA.
Not typically for basic error monitoring. A DPIA becomes advisable if error logs systematically capture user session identifiers or personal data, or if user-linked error reports are retained for profiling purposes.
Document a legitimate interest balancing test for error monitoring. Configure Cfix to minimise personal data in error reports. Sign a DPA. If persistent cookies are set, obtain ePrivacy consent. Disclose Cfix in your privacy policy. Document the US transfer in your RoPA.
Sentry offers EU data residency. Rollbar has EU processing options. For full EU sovereignty, Glitchtip is an open-source Sentry-compatible error tracker that can be self-hosted on EU infrastructure. Highlight.io also offers EU data residency.
Configure Cfix to scrub personal data from error reports before transmission, including masking email addresses, names, and other identifiers in error messages and stack traces. Disable user context linking unless strictly necessary for debugging. Set maximum retention periods for error logs. Use IP anonymisation if Cfix supports it.
