Do the generic package files expire?

I’m using the API to upload a zip file containing a built project as a generic package, like this:
curl --header “JOB-TOKEN: ${CI_JOB_TOKEN}” --upload-file $OUTPUT_FOLDER/${ZIP_NAME}.zip ${PACKAGE_REGISTRY_URL}/${TAG_NAME}/${ZIP_NAME}-${TAG_NAME}.zip

It works and everything, but I’m interested in knowing if the package has an expiration date because I’m not being able to find any reference to that in the docs.
