4Purpose and nature of the service

4.1. Through a Subscription, DoctorQuest provides access to a digital medical education platform for learning and looking up electrocardiography.

4.2. The purchase grants the User a fixed-term license to access the Content and features of the purchased Plan. It does not constitute the acquisition, ownership or permanent transfer of any material.

4.4. The Platform is intended solely for education and professional reference, as set out in Section 5.

5Educational purpose and medical disclaimer

5.1. The Content is purely educational and informational, intended for the training and continuing education of healthcare professionals and students. It does not constitute medical advice, diagnosis, prescription or treatment for specific patients, and it does not replace clinical judgment, individual patient assessment or consultation with a licensed professional.

5.2. Use of the Platform does not create a physician-patient relationship between DoctorQuest (or its authors) and the User or any third party.

5.3. Clinical, diagnostic and therapeutic decisions are the sole responsibility of the professional, who makes them with technical and ethical autonomy, in light of the specific case, current guidelines and institutional protocols.

5.4. The Content reflects the evidence available at the time of publication and may not incorporate the most recent guidelines. The User is responsible for checking the information against up-to-date sources before any practical application.

5.5. In urgent or emergency situations, the applicable care protocols must be followed and appropriate medical resources sought.

5.6. The ECG tracings, images and clinical cases in the Content are used for teaching and are presented in de-identified/anonymized form, so that patients cannot be identified, in compliance with Brazilian Law No. 13,709/2018 (LGPD, the Brazilian General Data Protection Law). Any clinical data shown is illustrative and does not constitute personal data of identifiable individuals.

6Artificial intelligence features

6.1. Certain Plans offer AI Features, which are educational tools that support study and interpretation.

6.2. AI-generated responses may contain inaccuracies, omissions or errors (“hallucinations”) and must always be critically assessed by the User. They should not be used as a sole source or as an automated diagnosis.

6.3. AI Features do not replace professional assessment or responsibility for clinical decisions, which remain human and non-delegable, in line with the rules of Brazil’s Federal Council of Medicine (Conselho Federal de Medicina) on the use of artificial intelligence as a support tool.

6.4. Data entered into AI Features is processed in accordance with the Privacy Policy. The User must not enter data that identifies real patients without an appropriate legal basis and purpose.

6.5. Use of AI Features is optional, and their availability depends on the purchased Plan. The User may stop using them at any time.

6.6. The User’s interactions with AI Features may be stored to allow continuity and personalization of study and to continuously improve the feature through anonymized analysis, as described in the Privacy Policy.

7Registration, account and credentials

7.3. Sharing the account, credentials or access with third parties is prohibited, as is assigning, lending or transferring the account.

8.4. Price changes will be communicated in advance and apply only to subsequent renewals.

8.5. Where the offer allows payment in installments, installments are only a method of paying for the purchased annual or two-year Plan and do not convert it into a monthly subscription.
