(2) Coaching / consulting clients— name, email address, payment information (handled by Stripe / PayPal), and any information you choose to share about your goals or project.
(3) Newsletter / update list (Google Form)— for people interested in careers or life in Japan who choose to share their email, name, background, occupation, Japanese level, and related information via an optional Google Form, used only to send updates and announcements about our services.
Information collected under (1), (2), and (3) is kept separate and is not automatically merged, even if the same email address appears in more than one place.
