Last updated: 21 October 2026
Haccly is in a pilot phase. These documents describe the rules that already apply or have been decided. Points not yet decided are marked as such. Before sales start, a lawyer reviews the documents and we publish the final versions.
In short
We use no advertising, analytics or tracking cookies. Everything we save in your browser is needed for the website or app to work, or remembers a choice you made. That is why there is no consent banner: consent is not required for storage that is strictly necessary to provide a service you asked for (Polish Electronic Communications Law, Article 399).
