By accessing or using HeyDoctor, you acknowledge that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated herein by reference. If you do not agree with any part of these Terms, you must not use the Service.

We reserve the right to modify these Terms at any time. Material changes will be communicated through the Service or via email where possible. Your continued use of the Service after any modification constitutes acceptance of the revised Terms. It is your responsibility to review these Terms periodically.

2. Eligibility

The Service is available only to individuals who are at least 18 years of age. By using HeyDoctor, you represent and warrant that you are at least 18 years old and have the legal capacity to enter into these Terms. If you are under 18, you are prohibited from using the Service.

3. Nature of the Service --- Important Medical Disclaimer

HeyDoctor is an entertainment and educational game. It is not a medical device, diagnostic tool, clinical decision-support system, or substitute for professional medical advice, diagnosis, or treatment.

The clinical cases, AI-generated patient responses, investigation results, diagnoses, and explanations presented within HeyDoctor are fictional, simplified, and designed for gameplay purposes. They do not reflect real patients, real clinical encounters, or current clinical guidelines.

You must never rely on any information provided by HeyDoctor to make real-world medical decisions. Always seek the advice of a qualified healthcare professional for any medical condition or concern. If you are experiencing a medical emergency, call your local emergency number immediately.

HeyDoctor does not provide Continuing Medical Education (CME) or Continuing Professional Development (CPD) credits. No certification, accreditation, or professional qualification is awarded through use of the Service.

The Operator expressly disclaims all liability arising from any reliance placed on the content of HeyDoctor by any user or any person who may be informed of its contents.

4. Account and Access

4.1 Device-Based Identification

HeyDoctor uses anonymous, device-based identification (UUID) to manage your game sessions and progress. You are not required to create an account or provide personal information to use the Service. Your progress, scores, and streaks are tied to your device.

4.2 Your Responsibilities

You agree to use the Service only for lawful purposes and in accordance with these Terms. You shall not:

• Attempt to reverse-engineer, decompile, or disassemble any part of the Service;
• Use automated scripts, bots, or other means to interact with the Service or to circumvent message limits, rate limits, or other usage restrictions;
• Interfere with or disrupt the integrity or performance of the Service or its underlying infrastructure;
• Attempt to gain unauthorised access to any part of the Service, other users data, or the Operators systems;
• Impersonate any person or entity, or misrepresent your affiliation with any person or entity;
• Use the Service for any commercial purpose without the Operators prior written consent;
• Share, distribute, or publicly disclose daily case solutions, diagnoses, or AI patient responses before the 24-hour case period has ended, in a manner that spoils the experience for other players.

5. The Game

5.1 Daily Cases

Each day at 00:00 UTC, a new clinical case is released globally. All players encounter the same case on the same day. Each case remains active for 24 hours.

5.2 AI Patient Interactions

HeyDoctor features an AI-powered simulated patient. The AI patient responds based on a pre-authored Clinical Case Document (CCD) and does not generate medical information beyond its scripted parameters. AI responses may occasionally be imperfect, inconsistent, or unexpected. The Operator does not guarantee the accuracy, completeness, or clinical appropriateness of any AI-generated response.

5.3 Message Limits

All players are limited to 30 messages per case. Messages include both patient dialogue and clinical investigation requests. When your message limit is exhausted, you must submit a final diagnosis.

5.4 Diagnosis Submission

You may submit up to 3 diagnosis attempts per case. Diagnoses are selected from a curated list of medical conditions via searchable autocomplete. The list is maintained at the Operators sole discretion and may be updated at any time.

5.5 Scoring and Leaderboards

Scores are calculated server-side and are final. The Operator reserves the right to adjust scoring algorithms, remove fraudulent scores, or reset leaderboards at any time without prior notice. Leaderboard positions do not confer any prize, reward, or entitlement.

6. Subscriptions and Payments

6.1 Free tier access

Without a HeyDoctor Pro subscription, you may play one (1) case per calendar week. A week runs from Monday through Sunday in Coordinated Universal Time (UTC). Once you have started a case in a given UTC week, starting additional cases in that week requires a Pro subscription until the next UTC week begins. No payment information is required to use the free tier.

6.2 HeyDoctor Pro Subscription

HeyDoctor Pro is offered as a weekly or monthly subscription at the price shown at checkout (subject to change with reasonable notice). Current prices are listed at heydoctor.io/#pricing.

Prices are inclusive of VAT where applicable. The Operator reserves the right to adjust pricing. Any price increase will apply only from the next billing cycle and will be communicated at least 30 days in advance.

6.3 Payment Processing

Payments are processed securely through RevenueCat, with card payments handled by Stripe. The Operator does not store or have direct access to your full payment card details. By subscribing, you agree to RevenueCat's and Stripe's terms of service in addition to these Terms.

6.4 Automatic Renewal

Subscriptions renew automatically at the end of each billing period (monthly or annual) unless cancelled before the renewal date. You may cancel at any time through your account settings. Cancellation takes effect at the end of the current billing period; you will retain access to Pro features until that date.

6.5 Refund Policy

Due to the digital nature of the Service, the following refund policy applies:

• If you have not used any Pro features (played any cases as a Pro subscriber) since your most recent payment, you may request a full refund within 14 days of that payment.
• If you have used Pro features, refunds are generally not available, as the digital content has been consumed. However, we will consider refund requests on a case-by-case basis in circumstances such as technical issues that prevented you from using the Service.
• To request a refund, contact us at support email. We aim to process all refund requests within 14 business days.
• This policy does not affect your statutory rights under Italian or European Union consumer protection law, including the right of withdrawal under Directive 2011/83/EU, to the extent applicable.
