Haskell is a purely functional, statically typed programming language used to build applications and backend services, including web applications through frameworks such as Yesod and Servant. The language itself does not set cookies, track users, or transfer data. Any privacy obligations come from what a developer builds with it, so a site detected as using Haskell has a low inherent privacy footprint that depends on its own implementation.
Haskell is a purely functional, statically typed programming language. It is used to build applications, backend services, and web applications, often through frameworks such as Yesod, Servant, and Scotty. As a language it runs on the server and is part of how a product is built rather than a third party service added to a page.
By itself, Haskell does not set cookies, track visitors, or send data anywhere. It has no built in analytics or advertising. If an application built in Haskell uses sessions, it may set a first party session cookie, but that is a choice of the application rather than a behaviour of the language.
The GDPR applies to the processing of personal data, and a programming language does not process anything on its own. The obligations attach to the application a developer builds, including what data it collects, what cookies it sets, who it shares data with, and where it is hosted, so compliance work belongs at the application level.

There is no consent requirement for using Haskell as a language. Consent obligations arise only if the application built with it sets non essential cookies or runs analytics and marketing, in which case those specific features must be handled like any other tracking technology.
Because Haskell applications are self hosted, the data location is wherever the developer runs the software. There is no transfer to a language vendor. If you host within the European Economic Area, there is no international transfer arising from the language itself.
Treat compliance as a property of the application, not the language. Document the cookies and data your Haskell application actually uses, set a lawful basis and retention for any personal data, host within the EU where possible, and apply consent to any analytics or marketing you add. The language itself needs no cookie banner entry.
Websites using Haskell must obtain user consent under GDPR regulations.
DPIA considerations
The language itself does not process personal data, so there is nothing to assess at that level. Any DPIA should focus on the specific application built with Haskell, its data flows, cookies, and hosting, not on the language.
Sample consent text
This site is built with the Haskell programming language, which does not set cookies or track you by itself. Any cookies or tools used by the site are described separately and run only with your consent where required.
This service may collect user data. Ensure GDPR compliance with FlowConsent.
No. Haskell is a programming language and sets no cookies by itself. If an application built in Haskell uses sessions, it may set a first party session cookie, but that comes from the application, not the language.
No, not for the language. Consent obligations only apply to non essential cookies or tracking that the application built with Haskell chooses to use.
There is none at the language level, because the language does not process personal data. Any lawful basis applies to the specific application and the data it handles.
No. As a self hosted language it transfers nothing to a vendor. Data location depends entirely on where you host the application you build.
Not for the language. If a DPIA is needed, it concerns the application you build with Haskell and its data flows, cookies, and hosting.
Focus on the application. Document the cookies and personal data it uses, set a lawful basis and retention, host in the EU where possible, and apply consent to any analytics or marketing you add.
Other server side languages such as Go, Rust, Elixir, and Java play a similar role. From a privacy standpoint, all of them are neutral, and compliance depends on what you build.
You do not need an entry for the language itself, because it sets no cookies. List only the cookies your application actually uses, including any first party session cookie.
