2. Access data and server log files

When this website is accessed, technically necessary access data is processed. This may include in particular the IP address, time of access, requested URL, referrer, user agent, HTTP status, and technical connection data. The processing serves the secure and stable operation of the website, error analysis, and protection against misuse.

3. User account and sign-in

Signing in is required to submit jokes and for moderation features. In doing so, the data necessary for sign-in, assignment, and permission checks is processed, in particular the user identifier, e-mail address, and technical session data.

4. Sign-in via Google

Sign-in can take place via Google. Google is integrated as an external identity provider. As part of the authentication, the data required for sign-in is processed, in particular the user identifier provided by Google as well as profile and e-mail data.

5. Submission and moderation of jokes

When you submit a joke, we store the entered text, language, time of submission, the associated user account, the processing status, and technical review data. The submission is processed for moderation, misuse prevention, duplicate detection, and possible publication.

5a. Ratings and favorite jokes

Signed-in users can rate published jokes with a thumbs up or thumbs down. We store which user rated which joke, the value of the rating, and the time of creation and last change.

Upvotes are used to show the user their favorite jokes. Ratings may also be used in aggregated form to evaluate the quality and popularity of jokes, prepare rankings, and improve the platform. Currently only the total number of upvotes is shown publicly. Downvotes are not shown as a public count and are not publicly attributed to individual users.

The processing serves to provide the rating and favorite-joke feature as well as to improve the platform and prevent misuse. Users can remove a rating by clicking the same rating again or change it by selecting the other rating.

If a user account is deleted, the ratings associated with that account are also deleted, unless legal retention obligations prevent this.

6. AI-supported analysis and joke explanation

To support moderation and to create or prepare joke explanations, joke texts and associated working data may be transmitted to an AI service provider. In particular, the joke text, existing categories, humor types, and joke patterns are processed. The results are stored in the platform and used editorially.

No confidential or third-party personal data should be entered into joke texts.

7. Misuse protection and rate limits

To limit abusive use, technical characteristics are processed. The IP address is used for rate limits and stored as a hash. The hash serves to detect repeated submissions within a short time without storing the IP address in plain text in the submission.

8. Cookies

This website uses technically necessary cookies. These include in particular cookies for sign-in, session management, and security features such as CSRF protection. These cookies are required for the operation of the website.

No additional rating cookies are set for rating jokes. Ratings are only attributed server-side to signed-in user accounts.

9. Recipients and processors

Personal data may be transmitted to technical service providers insofar as this is necessary for operation, sign-in, hosting, misuse protection, or AI-supported processing. This may include in particular hosting providers, Google as the login provider, and the AI service provider used.

10. Storage period

Personal data is only stored for as long as necessary for the respective purposes. Server logs are stored for a limited time. User accounts, submissions, ratings, favorite-joke assignments, moderation data, and published content are stored as long as they are required for platform operation, user features, moderation, documentation, or publication. IP hashes for rate limits should be deleted or anonymized after the misuse-protection purpose has expired.

11. Rights of data subjects

Data subjects have in particular the right to information, rectification, erasure, restriction of processing, data portability, and objection. There is also a right to lodge a complaint with a data protection supervisory authority.

12. Obligation to provide data

Use of the publicly available content is generally possible without signing in. For submissions, ratings, favorite jokes, and moderation features, the required sign-in, session, rating, and content data is necessary. Without this data, the respective features cannot be provided.
