AI transparency

1. Where we use AI

• Learning material: the exercise texts, tasks, grammar explanations, pictures and audio recordings (synthetic voices) are prepared in advance with the help of AI. They are produced editorially, with no user data of any kind, and we review them before publication — even so they may contain errors.
• AI evaluation: your written answers, picture descriptions and short voice recordings are assessed automatically by an AI system. The assessment is a learning aid: it may contain errors, it is not an official exam result, and we give it to nobody but you.
• What AI does not do: it does not decide what you are shown, it does not build a profile of you, and it does not predict how you will do in the exam. Auto-checked exercises (reading, grammar, listening) are marked against a prepared answer key, without AI.

2. How we mark AI-produced content (Art. 50 AI Act)

• A notice before every interaction with AI: before you submit an answer you are told, at the exercise itself, that an AI system will assess it (Art. 50(1) AI Act). The notice sits at the control you use, not buried in this document.
• A note beside every assessment: the assessment is for practice only, may contain errors, and is not an official exam result.
• A note about synthetic voices on the listening exercises.
• Machine-readable marking, in three layers. (1) Pages that carry AI-produced content declare "ai-generated-content" in the document head, with the standardised IPTC identifier "trainedAlgorithmicMedia" as its value. (2) The main content region of those same pages carries an attribute marking AI-generated content. (3) Audio files, exercise data files and illustrations are served with the response header "X-AI-Generated", whose value is that same standardised identifier.
• What is not marked, and why. We embed no metadata (IPTC/XMP or ID3) inside the files themselves — we say so openly rather than leaving it unsaid: our marking works through the three layers described above, not inside the file. Nor do we mark the brand and identity assets of the Service — the wordmark, the favicon, the home-screen icon and the social preview image: they are drawn directly by the site's own code from a typeface and a plain colour gradient, no model output goes into them, and so we assert nothing about them either way. Nor do we mark this document, the Terms of Service, the Privacy Policy or the "Contact" page: they are human-written documents, not content within the meaning of Art. 50.
• Marking text: there is as yet no single technical standard for text. The value in the document head and the attribute in the page are our documented best effort under the state of the art, not a claim of a verifiable watermark.

3. Our role under the AI Act

We offer the AI evaluation system under our own name and are therefore its provider within the meaning of Art. 3(3) AI Act — the fact that it is free of charge changes nothing, because the definition says so expressly. We are not merely a deployer. The third-party AI models with which we prepare material in advance, and which assess your answers, we merely use; they are supplied by the processor named in the Privacy Policy (OpenAI Ireland Ltd.). We do not publish the name of the particular model — it changes, and naming it would publish a detail that goes stale.

Since when we mark: the transparency obligations in Chapter IV of the AI Act, Art. 50 among them, have applied since 2 August 2026. We therefore mark from the moment the Service is publicly reachable; we rely on no later date.

4. What we ask of you, and what we do not

Please do not put special categories of personal data (for example health, origin, religious belief or political opinions) or other people's personal data into your answers or recordings — we do not need them for the assessment. This is a request, not a filter: the system does not look for such data or separate it out; your whole answer is sent for processing and assessed as a whole. The request we send carries no name, no e-mail address and no other user identifier.

Whether and how you learn with our material is entirely your decision. The AI evaluation replaces neither a teacher nor an official exam result — a certificate is obtained only by sitting the examination at the institution that organises it. We are an independent private project and are not connected with any examination institution or authority.
