THE USER EXPRESSLY ACKNOWLEDGES AND AGREES THAT:
• Content generated is created by automated algorithms and may contain factual errors, inaccuracies or inappropriate material
• The Service does not replace professional educational assessment or expert review
• The Provider gives no warranty as to the accuracy, completeness or suitability of generated content for any particular purpose
• Users must independently verify any generated content before use in official or high-stakes contexts
• Generated Content may be similar or identical to content generated for other users; the Provider does not guarantee the originality or exclusivity of the content
• The Provider does not guarantee that Generated Content does not infringe the rights of third parties, including intellectual property rights; the User is responsible for verifying compliance before any use
• Grades, scores and results generated by the Service are provided for indicative purposes only and do not constitute official, certified or academically recognised assessments under any circumstances
IMPORTANT WARNING REGARDING ASSESSMENTS:
Grades and scores attributed by the Service are automatically generated by algorithms and:
• MUST NOT be used as official assessments in a school, university or professional context
• DO NOT constitute a recognised certification, diploma or qualification
• CANNOT serve as the basis for admission, recruitment or advancement decisions
• MAY contain assessment errors for which the Provider disclaims all responsibility to correct
The User who uses the Service's results for official purposes does so at their own risk and releases the Provider from all liability for the consequences of such use.
The Provider guarantees no learning outcomes, academic improvement or examination success. The pedagogical effectiveness of the Service depends on many factors beyond the Provider's control.
The Service offers the following features:
• Quiz: a series of multiple-choice questions generated from the User's Content, with automatic correction
• Exam: an interactive session simulating an oral examination conducted by a virtual teacher based on artificial intelligence
• Summary: a structured synthesis of the User's Content, automatically generated

The Service enables content generation from text prompts entered by the User (for example: "create an exam about World War II"). The User acknowledges and agrees that:
• Content generated from text prompts is based on general information sources and may contain errors, inaccuracies or outdated information
• The Provider has no control over the content of the User's prompts and disclaims all liability as to their relevance or legality
• The User is solely responsible for verifying the accuracy of the generated content
• Results may vary and are not guaranteed to match the User's expectations
The Service may offer voice input and text-to-speech features. These features may use:
• The native capabilities of the User's device (system speech recognition and text-to-speech)
• Third-party online services for voice processing, in particular the OpenAI Whisper service for audio transcription
The User acknowledges and agrees that:
• The accuracy of speech recognition depends on many factors (audio quality, accent, environment) and is not guaranteed
• Voice data may be transmitted to third-party service providers for processing, in accordance with the Privacy Policy
• The Provider is not responsible for transcription or text-to-speech errors
• Use of third-party voice services is subject to the terms and conditions of those providers
The "exam" feature includes an interactive mode simulating an oral examination, in which the system asks questions and the User responds freely. The User acknowledges and agrees that:
• The "professor" or "teacher" in exam mode is an automated system based on artificial intelligence, and not a real person
• Questions are generated by algorithms and may contain errors or inaccuracies
• Assessment of answers is carried out automatically and does not replace assessment by a qualified educator
• The Provider is not responsible for the quality of the interaction or the pedagogical value of the dialogue
The Service offers a flashcard review feature, available in two modes:
Swipe Mode: the User views the front of the card, considers their answer, turns the card over to see the back, then indicates whether they have memorised the term or not. This mode does not involve any automated assessment.
Learn Mode: the User types or dictates their answer, which is transmitted to an artificial intelligence system for assessment. The result (correct, partial, incorrect) is provided for indicative purposes.
• Assessment in Learn Mode is automated and may involve errors of judgement
• The Provider does not guarantee the accuracy of generated flashcards or their suitability for any particular educational programme
• The history of learning sessions is retained in order to offer review adapted to cards not mastered in previous sessions
• Flashcards may be shared publicly via a link, under the conditions set out in Article 7
The Service may send push notifications to the mobile devices of Users with an account, subject to their explicit consent.

• Disabling push notifications at the profile level applies to all of the User's registered devices
• Device tokens are retained even if notifications are disabled, to allow reactivation without reconfiguration
• Device identification data is transmitted to Apple and Google as part of notification delivery, in accordance with the Privacy Policy
