The Day Rate Check is an online questionnaire that generates a personalised day rate report based on a few inputs and delivers it by email. The processing involves several service providers, each listed individually below.
Answers to the questionnaire (including field of work, experience level, current day rate, region), your email address for delivery of the report, and technical metadata (timestamps, device information).
Art. 6(1)(a) GDPR (consent), and for any data transfers to third countries Art. 49(1)(a) GDPR (explicit consent for international transfer). Consent is given explicitly at the end of the questionnaire before submission.
As part of the Day Rate Check, personal data may be transferred to countries outside the European Economic Area, in particular to the United States. Such transfers take place on the basis of your consent and appropriate safeguards (Standard Contractual Clauses, EU-US Data Privacy Framework). You acknowledge that the level of data protection in third countries may not match that of the EU and accept this when giving your consent.
Questionnaire answers and your email address are stored until you withdraw your consent or request deletion, but no longer than 24 months. Aggregated, no longer personally identifiable analyses may be retained beyond that.
The following processors are involved in the Day Rate Check:
Hosting of the application page at /day-rate-check.
Hosting the online questionnaire and storing your submitted answers.
Workflow automation: routing your answers to the downstream services (OpenAI, PDFMonkey, Brevo).
AI-powered benchmark calculation and generation of personalised report text.
Generating the personalised PDF report from your answers and the OpenAI output.
Delivering the finished report by email to the address you provided.
You can withdraw your consent at any time, with effect for the future, by sending an email to jan@janbarkhau.com. The lawfulness of processing carried out before withdrawal is not affected. On request, your data will be deleted across all of the systems listed above.
