2. Collection and processing of personal data

I only collect and process personal data when users voluntarily provide it, such as when booking a Chemistry Check via Cal.com, Inc., writing to me through the contact form or writing me an email. The data collected includes:

• Name (to personalize communication)
• Email address (for scheduling confirmations and responses)
• Your message, if you use the contact form (to reply to you)

The contact form sends your name, email address and message as an email to me via this website’s server (Uberspace). Nothing from it is stored on the server.

This data is not shared with third parties and is used solely for communication regarding the scheduled appointment or inquiries.

3. Purpose and legal basis for processing

The collection and processing of personal data is based on:

• Art. 6 (1) lit. b GDPR (contractual necessity): data is required to schedule and confirm the Chemistry Check.
• Art. 6 (1) lit. f GDPR (legitimate interest): to respond to inquiries and manage communications.

4. Data retention

• Email and contact form inquiries are stored until the conversation is complete or no longer necessary.
• Data from Cal.com, Inc. is stored until the appointment has passed.
• You may request deletion of your personal data at any time.

5. Third-party services and data processing

I use third-party services to operate my website:

Cal.com, Inc. (appointment scheduling). For appointment scheduling, I use Cal.com, Inc. When booking a meeting, your name and email are collected and processed via Cal.com. Legal basis: processing is based on Art. 6 (1) lit. b GDPR (contractual necessity) as this service is required to manage scheduled meetings. Cal.com’s privacy policy: cal.com/privacy

Uberspace (Jonas Pasche, Mainz, hosting provider, Germany). For hosting this website and sending messages from the contact form. Privacy policy: uberspace.de/en/about/privacy

Strato AG (email, Germany). For the mailbox hey@revolutioncoaching.de, where emails and contact form messages arrive. Privacy policy: strato.de/datenschutz

These providers may collect server logs (IP address, browser type, time of access) for security reasons. I have no control over this data processing.

6. User rights under GDPR

As a visitor of this website, you have the right to:

• request access to your stored data (Art. 15 GDPR),
• request correction or deletion of your data (Art. 16 and 17 GDPR),
• object to data processing based on legitimate interests (Art. 21 GDPR).

For any inquiries, you can contact me via hey@revolutioncoaching.de.

7. Data security

I take reasonable measures to protect personal data from unauthorized access. However, data transmission over the internet (e.g. emails) can have security vulnerabilities.

8. Updates to this privacy policy

This privacy policy may be updated periodically. The latest version is always available on this website.
