Privacy Notice
Plain language. Short list. No tracking pixels, no third-party advertisers.
Kirby, Let’s Go is a trade name of Yu Collective LLC, based in San Mateo County, California. The data controller is Catherine Yu. For any privacy question or request, email cat@kirbyletsgo.com.
Only what you give us through forms on this site — primarily the lesson questionnaire. That includes:
We do not use third-party advertising cookies or fingerprinting. We do not buy or sell personal data.
Consent (Art. 6(1)(a) GDPR). We process your data only after you check the explicit consent boxes on the questionnaire. The purposes are: (1) to prepare for and schedule your training session, (2) to contact you about the session, and (3) where you grant the media release, to use photos or video taken during training in our portfolio. Each consent is granular and independent.
Questionnaire submissions are delivered to Catherine’s inbox via Google Workspace (Gmail). Google acts as a sub-processor under its standard data-processing terms. We do not forward your data to any other party. If you book a payment, Square processes the payment under its own privacy policy — we never see your card details.
Questionnaire emails are retained for up to 36 months so we can refer to context during follow-up sessions. After that we delete or anonymize them. You can ask for earlier deletion at any time (see “Your rights” below).
Email and uploaded files are stored on Google’s infrastructure (primarily US data centers). Standard contractual clauses apply for transfers from the EEA / UK to the United States.
You have the right to:
To exercise any right, email cat@kirbyletsgo.com with the subject line “Data request”. We’ll respond within 30 days at the latest, usually faster.
How corrections work in practice. Because your submission is delivered as an email, the original message is immutable. To correct it, we’ll either (a) reply to the original thread with your correction so the record, read end-to-end, reflects the up-to-date version, or (b) delete the original entirely and ask you to resubmit — your choice. Both satisfy the GDPR right to rectification.
The site uses strictly-necessary cookies only (for example, to remember your draft questionnaire answers in your own browser via localStorage). No analytics or advertising cookies are set.
The services here are for adults. We do not knowingly collect data from anyone under 16.
If we materially change how we handle your data, we’ll update this page and date the change below. Continued use of the site after that constitutes acceptance.
