Privacy policy
How we collect, process and protect your data, in plain words, with no hidden jargon.
Preamble
At Calerys, privacy is not a checkbox. It's a foundational commitment.
You trust us with information that's sometimes very personal: your weight, your eating habits, your goals, sometimes your struggles. This policy explains precisely, and without dodging, how that data is processed, protected, and what your rights are.
Processing is governed by:
- The General Data Protection Regulation (GDPR), regulation (EU) 2016/679;
- The Swiss Federal Act on Data Protection (nFADP), the revised version of which entered into force on September 1, 2023;
- Applicable standards for sensitive data, in particular health data.
The phone number used to sign in to the iOS app is used only to operate the service. It is not used for marketing campaigns, advertising audiences or advertising measurement.
We never sell your data and use no data brokers. On the website, with your consent (marketing category), we share pseudonymised data, SHA-256-hashed email and phone, with Meta for the sole purpose of measuring the effectiveness of our ads. No intrusive commercial profiling, no tracking beyond what is necessary.
1. Data controller
Eatten Sàrl, Business ID CHE-351.622.923
Registered office: Lausanne, Switzerland
Contact: timitten@live.fr
1.1 Data Protection Officer (DPO)
As a small organisation, Eatten Sàrl is not legally required to appoint a formal DPO within the meaning of GDPR article 37. Nevertheless, a dedicated point of contact for data protection matters is in place:
Tim Schneider, Data Protection Lead
Email: timitten@live.fr (mention “DPO” in the subject)
Target response time: 7 working days
2. Data we collect
2.1 Identification data
- First name (or nickname), possibly last name
- WhatsApp phone number (the main Service identifier)
- Email address (for billing and critical notifications)
- Country / time zone (to tailor reminders)
2.2 Payment data
Payments are fully handled by Stripe Inc. Calerys never stores card numbers, security codes or banking credentials. We only receive:
- A Stripe customer identifier
- Subscription status (active, paused, cancelled)
- Billing information (amount, date, currency)
2.3 Health and wellbeing data (special category)
Some of the data collected falls under the special category within the meaning of GDPR article 9 and article 5 let. c nFADP: weight, height, age, nutritional goals, declared allergies, intolerances, conditions mentioned by the user, physical activity.
This data is only processed with your explicit consent, collected during onboarding, and only for the purpose of providing the Service. You can withdraw this consent at any time.
2.4 Conversation data
- Text messages exchanged with Calerys on WhatsApp
- Meal photos and other media you send
- Message metadata (date, time, delivery status)
2.5 Technical data
- Server logs (IP address, user-agent, timestamps): retained for 30 days maximum
- Technical session identifiers
- Performance and error analytics data (aggregated and anonymised)
- Country inferred from your IP address, solely to display prices in your local currency. On your first visit, your IP address is sent to a third-party geolocation service (geojs.io, with ipapi.co as a fallback) for the duration of the request; only the resulting country code is kept, stored in a cookie on your device to avoid any further request. No personal data is retained by that service on Calerys's behalf.
3. Purposes of processing
We use your data strictly to:
- Provide the Service: analyse your meals, generate nutritional recommendations, track your goals, produce reports, send reminders.
- Personalise your recommendations: adapt advice to your profile, constraints and history.
- Manage your subscription: billing, renewal, customer support.
- Secure the Service: fraud, abuse and attack prevention.
- Improve Calerys: anonymised and aggregated analytics only. No re-identification possible.
- Comply with our legal obligations: notably Swiss accounting and tax obligations.
4. Legal bases
- Performance of the contract (GDPR art. 6.1.b), To provide the Service you subscribe to.
- Explicit consent (GDPR art. 6.1.a and 9.2.a, nFADP art. 6), For health and wellbeing data.
- Legal obligation (GDPR art. 6.1.c), For invoice retention (10 years, Swiss law).
- Legitimate interest (GDPR art. 6.1.f), For Service security, fraud prevention and anonymised product improvement.
5. Recipients and processors
The providers involved in delivering the service are listed below, with their roles and locations. You can contact us for information about data processing agreements (DPAs) and the safeguards applicable to the processing concerned.
| Processor | Role | Location |
|---|---|---|
| Stripe | Payment processing | USA (DPF certified) |
| Meta (WhatsApp Business) | Message transmission | EU / USA (DPF) |
| DeepInfra | AI inference on conversations and the context needed for replies | United States |
| OpenAI / Anthropic | AI processing of conversations | USA (DPF, training opt-out) |
| Supabase | Encrypted storage at rest | Germany (Frankfurt) |
| Railway | Application hosting | USA / EU |
| geojs.io / ipapi.co | IP geolocation (displayed currency) | USA |
| PostHog (EU) | Anonymised analytics (optional) | EU (Frankfurt) |
| Meta Platforms Ireland Ltd | Ad measurement, Meta Pixel + Conversions API (only with your marketing consent; SHA-256-hashed email and phone) | Ireland / USA |
No other recipients. We do not sell your data, use no data brokers, and rely on no third-party retargeting platforms. Sharing with Meta is limited to measuring the effectiveness of our ads, and only if you have accepted the marketing category.
5.1 Ava and processing by AI providers
Ava is an artificial intelligence. To prepare its replies, Calerys shares the messages, photos and voice notes you send, together with relevant context from your conversation history and tracking, with DeepInfra, OpenAI or Anthropic, depending on the processing. This content may include health data you choose to share.
In the iOS app, an unchecked consent box on the sign-in screen lets you authorise this processing before using Ava. This consent is associated with your account and the version of the notice presented.
You can withdraw this consent in “My account” using “Withdraw my AI consent”. Withdrawal signs you out and stops new messages from the iOS app. It does not cancel requests already sent or conversations on other channels. To exercise your rights over all your data, see section 8 of this policy.
6. Transfers outside the European Union
Some of our processors (Stripe, DeepInfra, OpenAI, Anthropic, Meta) are established in the United States. The applicable safeguards depend on the provider and the processing concerned. They may include:
- Adherence to the EU-US Data Privacy Framework (DPF) when the processor is certified;
- Standard Contractual Clauses (SCCs) approved by the European Commission (decision 2021/914);
- Additional technical measures: encryption, minimisation of transferred data, segregation of health data.
For Switzerland, the Swiss-US Data Privacy Framework may provide a basis for a transfer to the United States when the provider is certified and the processing falls within the scope of that certification. This safeguard does not automatically apply to every provider.
7. Retention period
- Active account: duration of the subscription + 3 years after the last interaction (justified by possible contractual obligations and the possibility of reactivation).
- Conversation, meal and measurement data: kept for as long as your account exists, then under the rule above. Your history is what makes the tracking possible: a weight curve, an eating habit or a trend can only be read over time. You can request deletion at any time.
- Deleted account: effective deletion within 30 days of the request, except for legal obligations to the contrary.
- Invoices and accounting documents: 10 years (Swiss legal obligation, art. 958f CO).
- Technical logs: 30 days.
- Aggregated anonymised data: no time limit, as it is not linkable to an identifiable person.

8.1 Right of access
