Privacy Policy

Calo (“we”, “us”, “our”) is operated by Stefan Neuber, Stahnsdorfer Straße 140a, 14482 Potsdam, Germany. This policy explains what personal data we collect when you use textcalo.com and the Calo iMessage service, how we use it, and the rights you have under the EU General Data Protection Regulation (GDPR) and other applicable laws.

1. Who is responsible

The data controller for the purposes of GDPR Art. 4(7) is:

Stefan Neuber
Stahnsdorfer Straße 140a
14482 Potsdam, Germany
Email: neuberapps@gmail.com

2. What data we collect

2.1 During onboarding on textcalo.com

• Self-reported attributes: gender, activity level, goal, height, weight, birthday, target weight, diet preference, and how you heard about us.
• Your mobile phone number, which we use to verify your identity and connect you with Calo in iMessage.
• Technical data: IP address, user agent, and basic device information, used to provide the service securely.

2.2 When you chat with Calo

• The messages you exchange with Calo (text, photos of food, voice notes).
• Metadata derived from those messages (food items recognized, calorie and macro estimates, time of day).
• Preferences, goals, and context you share so Calo can personalize his replies.

3. Why we collect it (legal bases)

• To provide the service (GDPR Art. 6(1)(b) — contract). Calculating your nutrition plan, verifying your phone number, and powering the Calo conversation.
• To improve and secure Calo (Art. 6(1)(f) — legitimate interest). Aggregated and anonymized analytics, fraud prevention, and abuse detection.
• With your consent (Art. 6(1)(a)). Optional marketing, research participation, or anything we ask you about separately. You can withdraw consent at any time.
• To comply with legal obligations (Art. 6(1)(c)). Such as responding to lawful requests from authorities.

4. Who we share it with

We do not sell your data. We share it only with the service providers that help us run Calo, under data processing agreements:

• Hosting & infrastructure: cloud providers in the EU/US that store and process data on our behalf.
• SMS / iMessage delivery: telecom partners that deliver verification codes and messages between you and Calo.
• AI processing: model providers that interpret your messages on Calo’s behalf. They receive only the content needed to generate a reply.
• Analytics: privacy-preserving analytics tools to understand product usage in aggregate.

When data is transferred outside the EU/EEA, we rely on EU Standard Contractual Clauses or equivalent safeguards.

5. How long we keep it

• Account & onboarding data: as long as you use Calo, plus up to 24 months after your last interaction.
• Conversation history: retained while you use the service so Calo can remember context. Deleted on request.
• Phone numbers used only for verification (where you didn’t complete signup): deleted within 30 days.
• Logs & security data: up to 90 days.

6. Your rights

You have the right to:

• Access the personal data we hold about you.
• Correct inaccurate or incomplete data.
• Delete your account and associated data.
• Restrict or object to certain processing.
• Receive a portable copy of your data.
• Withdraw consent at any time (without affecting prior lawful processing).
• Lodge a complaint with a supervisory authority. In Germany this is the Landesbeauftragte für den Datenschutz und für das Recht auf Akteneinsicht Brandenburg.

To exercise any of these rights, text Calo “delete my data” or email neuberapps@gmail.com. We respond within 30 days.

7. Security

We use industry-standard encryption in transit (TLS) and at rest, scoped access controls, and continuous monitoring. No system is perfectly secure, but we treat your data like our own — because eventually it will be.

8. Children

Calo is not designed for children under 16. If you are under 16, please don’t use Calo. If we learn we’ve collected data from a child under 16, we delete it.

9. Changes to this policy

We may update this policy as Calo evolves. When we make material changes, we’ll let you know by text or email before they take effect.
