🔒 GDPR

Privacy Policy

We take the protection of your personal data seriously. Here you'll find out what data we collect, how we use it and what rights you have.

1 · Controller

The controller within the meaning of the General Data Protection Regulation (GDPR) is:

Helmut Balzersen
Große Howe 7
33607 Bielefeld, Germany
E-Mail: info@derkiassistent.de

2 · Principles of Data Processing

We process personal data only where permitted by law or covered by consent. The legal bases are in particular:

  • Art. 6(1)(b) GDPR – Performance of a contract (providing the tool after purchase)
  • Art. 6(1)(f) GDPR – Legitimate interests (operation & security of the platform)
  • Art. 6(1)(c) GDPR – Legal obligations (tax, accounting)

3 · Hosting & Server Logs

When you visit the site the web server automatically stores the following data in server log files:

Date & time of accessError analysis7 days
URL accessedError analysis7 days

Important: Users' API keys are never stored in any server log. They are used solely to forward requests to Anthropic and are not persisted afterwards.

Legal basis: Art. 6(1)(f) GDPR (legitimate interest in operating and securing the platform).

4 · School Data in the Database

Purchasers of the AI Assistant can store the following data in a school profile, which is saved on our server in a MySQL database:

FieldExamplePurpose
School name"Surf & Kite School"Personalising AI replies
Prices"Beginner: €60/day"AI replies to booking enquiries

Licence code"KS-7X9M2"Linking data to the user

Data is deleted on request at any time – an e-mail is sufficient. Legal basis: Art. 6(1)(b) GDPR.

5 · API Key & AI Processing

To use the AI features, users enter their own Anthropic API key. This key is:

  • stored exclusively in the user's browser (localStorage)
  • transmitted temporarily to our server with each AI request
  • forwarded from our server to the Anthropic API
  • not stored in our database
  • not recorded in server logs

6 · Payment Processing (Digistore24)

Purchases are processed via Digistore24 GmbH (St.-Martin-Str. 78, 81541 Munich, Germany). Digistore24 acts as the contracting party and is independently responsible for payment processing. We only receive the e-mail address needed to deliver the product (licence code). Payment data is processed exclusively by Digistore24.

7 · Anthropic as Data Processor

To generate AI replies, text inputs (customer enquiries, school profile data) are transmitted to the API of Anthropic, PBC (548 Market Street, Suite 98777, San Francisco, CA 94104, USA).

Anthropic processes this data as a data processor under a Data Processing Agreement (DPA). As Anthropic is based in the USA, data is transferred to a third country. The basis for this is the EU Standard Contractual Clauses (SCCs) pursuant to Art. 46(2)(c) GDPR.

8 · localStorage in the Browser

The tool stores the following data locally in the user's browser via localStorage:

KeyContentPurpose
kiCodeLicence code (e.g. KS-7X9M2)Automatic login on next visit
kiApiKeyUser's Anthropic API keyNo need to re-enter the key

localStorage data never leaves the user's browser and is not transmitted to us. It can be deleted at any time via browser settings. localStorage is not a cookie and therefore does not require a cookie consent banner.

9 · Cookies & Tracking

We do not use tracking cookies. For anonymous usage statistics we use Matomo Analytics – self-hosted on our own server, with no transfer of personal data to third parties. No cookie banner is required.

Matomo Analytics is operated on our own server (matomo.derkiassistent.de). Only anonymised access data is collected (pages visited, approximate country of origin, device type). IP addresses are anonymised before storage. There is no cross-session tracking and no personal data is transmitted to third parties. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in anonymous usage analysis). More info: matomo.org/privacy

10 · Newsletter / AI Morning Briefing

Anyone who signs up for our free daily AI Morning Briefing enters their e-mail address and confirms the subscription via a double opt-in procedure: after submitting the form you receive a confirmation e-mail, and only after clicking the link it contains does the subscription become active.

To send the briefing and to document the consent (Art. 7 GDPR) we store the following data in our database:

Data categoryPurpose
E-mail addressSending the briefing
Consent text & versionProof of what exactly was consented to
IP address at sign-up & confirmationProof of consent (double opt-in)
Timestamp of sign-up & confirmationProof of consent
Status (pending / confirmed / unsubscribed)Managing the mailing list

Legal basis: Art. 6(1)(a) GDPR (consent).

Unsubscribe at any time: Every briefing e-mail contains an unsubscribe link. One click withdraws the consent and no further e-mails are sent. The withdrawal does not affect the lawfulness of processing carried out beforehand.

Storage period: The data is stored for as long as the subscription is active. After unsubscribing, the status is set to “unsubscribed”; the consent record may be kept for a limited time to meet legal proof obligations and is then deleted. Complete deletion is possible at any time by e-mail to info@derkiassistent.de.

Delivery: The e-mails are sent via our hosting provider (ALL-INKL.COM – Neue Medien Münnich). E-mail addresses are not passed on to third parties for advertising purposes.
