Dancer (Perl)
Dancer is an open-source Perl web microframework inspired by Sinatra (Ruby). It provides a simple, expressive routing DSL for building small to medium web applications in Perl. As a server-side framework, Dancer itself has no data collection. GDPR obligations depend on the application built with it, particularly how it handles user data, sessions, and logs.
What does Dancer (Perl) do?
What is Dancer (Perl)?
Dancer is a lightweight Perl web microframework inspired by Ruby's Sinatra. It provides a simple DSL for routing HTTP requests and building RESTful APIs and web applications. Being a server-side framework, Dancer processes HTTP requests on the server. GDPR obligations depend on what data the application logs, stores, and processes.
GDPR and Dancer
Dancer itself has no GDPR implications. As a server-side framework, GDPR applies to the application data it processes: HTTP request logs (which may include IP addresses), session data, form submissions, and any user data stored in databases. Configure server access logging to minimise IP address retention. Implement session timeouts and secure cookie flags.
Practical compliance steps
Configure secure, HTTP-only session cookies. Minimise server access log retention. Document all personal data processed in your application's RoPA. Apply GDPR at the application level for all user data handling.
Dancer (Perl) and the GDPR
- Legal basis
- Dancer is a web framework with no built-in data processing. GDPR obligations arise from the application built with it.
- Risk level
- low
- Applicable regulations
- GDPR compliance is the responsibility of the application developer
Impact assessment (DPIA)
A DPIA is not required for Dancer itself. It may be required for applications processing large-scale personal data.

Frequently asked questions about Dancer (Perl)
Can't find your question? Write to us, we answer fast.
Is Dancer (Perl) subject to GDPR?
Not as a framework itself. GDPR applies to the application built with Dancer and the user data it processes.
Does Dancer set cookies?
Dancer sets session cookies for application state. Configure secure, HTTP-only session cookies and implement appropriate session timeouts.
Do server access logs in Dancer contain personal data?
Yes. Dancer applications produce server logs that typically include IP addresses. Configure log retention limits and anonymise IPs where possible.
Do I need a DPIA for a Dancer application?
Not for Dancer itself. A DPIA may be required for specific application features processing sensitive data at scale.
Does Dancer transfer data outside the EU?
Only if the hosting infrastructure or backend services used are located outside the EU. Self-hosting on EU infrastructure avoids transfers.
Is Dancer still actively maintained?
Dancer (v1) and Dancer2 are maintained with periodic updates. Dancer2 is the current recommended version.
How do I secure sessions in Dancer for GDPR compliance?
Set session cookies with Secure and HttpOnly flags, implement CSRF protection, configure appropriate session timeout, and use encrypted session storage.
What GDPR compliance is needed for a Dancer application?
Apply GDPR at the application level: secure session handling, access log minimisation, data subject rights endpoints, DPAs with hosting providers, and privacy notice disclosures.
