4. How We Use Your Data
We process personal data on the following legal bases under the EU General Data Protection Regulation ("GDPR"):
| Purpose | Legal basis (Art. 6 GDPR) |
|---|---|
| Provide and operate the Service (authentication, gameplay, leaderboards, activity history) | Performance of a contract (Art. 6(1)(b)) |
| Process payments via Stripe | Performance of a contract (Art. 6(1)(b)) |
| Send transactional emails (receipts, password resets, critical service notices) | Performance of a contract (Art. 6(1)(b)) |
| Product analytics and improvement | Legitimate interest (Art. 6(1)(f)) — we balance this against your rights by minimising data, anonymising where possible, and offering opt-out |
| Crash monitoring and security | Legitimate interest (Art. 6(1)(f)) |
| Marketing communications (product updates, new features) | Consent (Art. 6(1)(a)) — you can withdraw at any time |
5. AI-Powered Features and Conversation Data
The core gameplay involves free-text conversations with an AI-powered patient. These conversations are processed by third-party AI model providers, which may include Anthropic, OpenAI, and Google (Gemini), depending on the specific feature and model best suited for the task.
What this means in practice:
- Your messages are sent to the relevant AI provider's API to generate a response.
- We store the full conversation on our servers so you can review your activity history.
- We do not use your conversations to train or fine-tune any AI model.
- Each AI provider processes your messages in accordance with their own API data processing terms. Under their standard API terms, input and output data are not used to train their models.
We do not include your email address or display name in the data sent to AI providers. Conversations are associated with an internal session identifier only.
6. Third-Party Services
We use the following third-party processors, all of which process data within the European Economic Area (EEA) or under appropriate safeguards:
| Service | Role | Data processed | Location |
|---|---|---|---|
| Supabase | Database, authentication, hosting | Email, username, game sessions, conversations | EU |
| Vercel | Application hosting | IP address, request metadata | EU |
| Stripe | Payment processing | Payment details (card number, billing address) — Stripe is the sole processor of this data | EU/US (Stripe is certified under the EU-US Data Privacy Framework) |
| PostHog | Product analytics | Anonymised/pseudonymised usage events, device info, IP | EU (self-hosted or EU cloud instance) |
| Google Analytics | Product analytics | Anonymised usage events, device info, IP (anonymisation enabled) | EU/US (Google is certified under the EU-US Data Privacy Framework) |
| Anthropic | AI model provider | Conversation messages (no PII) | US (Standard API DPA; data not used for training) |
| OpenAI | AI model provider | Conversation messages (no PII) | US (Standard API DPA; data not used for training) |
| Google (Gemini) | AI model provider | Conversation messages (no PII) | US/EU (Standard API DPA; data not used for training) |
Where data is transferred outside the EEA, we rely on the EU-US Data Privacy Framework, Standard Contractual Clauses (SCCs), or an adequacy decision by the European Commission, as applicable.
7. Data Retention

| Account data (email, username) | Until you delete your account |

| Payment records | As required by Italian tax law (10 years for fiscal records) |
