Privacy Policy

Last updated: 25 May 2026
Please note: This is a working draft for general information. It has not been reviewed by a lawyer. Because Kadvar processes health-related data and operates in the EU under the GDPR, this policy should be reviewed by a privacy professional before launch.

This Privacy Policy explains how Kadvar ("we") collects, uses, and protects your personal data when you use our service. We are committed to handling your data responsibly and in line with the EU General Data Protection Regulation (GDPR).

1. Who is responsible for your data

The data controller is the individual operator of Kadvar, based in the Czech Republic. For any privacy questions or to exercise your rights, contact: support@kadvar.com. (A working contact is legally required before launch.)

2. What data we collect

To create your personalised plan, we collect information you provide during onboarding and use:

3. Sensitive (special category) data

Some of the data above — such as health, injury, and dietary information — may be considered special category data under the GDPR. We process it only with your explicit consent, given when you choose to provide it during onboarding, and solely to generate and adjust your fitness and nutrition plan. You can withdraw this consent at any time by deleting your account or contacting us.

4. Why we use your data and our legal basis

5. AI processing of your data — important

To generate your workout and meal plans, relevant profile information is sent to third-party AI providers (currently Anthropic and OpenAI) which process it to produce your plan. This data is sent for the purpose of generating your plan and is subject to those providers' own data-handling terms. We send only what is needed to create your plan. If you are not comfortable with this processing, please do not use the Service, as AI generation is core to how it works.

6. Who we share data with

We use trusted service providers ("processors") to operate Kadvar. We do not sell your personal data. These providers include:

Some of these providers may process data outside the EU. Where that happens, appropriate safeguards (such as Standard Contractual Clauses) should apply. [A lawyer should confirm the transfer mechanisms for each provider.]

7. How long we keep your data

We keep your data for as long as your account is active. If you delete your account, we delete or anonymise your personal data within a reasonable period, except where we must retain certain records (for example, payment records) to meet legal obligations.

8. Your rights under the GDPR

You have the right to: access your data; correct inaccurate data; delete your data ("right to be forgotten"); restrict or object to processing; data portability; and withdraw consent at any time. You also have the right to lodge a complaint with your local data protection authority (in the Czech Republic, the Úřad pro ochranu osobních údajů). To exercise any right, contact us at the email above.

9. Cookies

Kadvar uses only essential cookies and similar storage needed to keep you logged in and operate the Service. We do not use advertising or third-party analytics tracking cookies. [If you add analytics in future, this section must be updated and a cookie consent banner added.]

10. Security

We use reasonable technical and organisational measures to protect your data, including encrypted connections and access controls provided by our infrastructure providers. No system is perfectly secure, but we take your privacy seriously.

11. Children

Kadvar is not intended for anyone under 18, and we do not knowingly collect data from minors.

12. Changes to this policy

We may update this policy. Material changes will be communicated via the app or email.

To access, correct, or delete your data, or for any privacy question, contact support@kadvar.com.
