Privacy Policy
Effective 27 June 2026
This policy explains what Winjitsu collects, why, and what you can do about it. Winjitsu is operated by Rick Tew.
What we collect
When you sign up we collect your name and email. As you use the app we store your progress, such as the chapters you read and the techniques you work. If you pay for a feature, the payment is handled by our payment provider; we do not see or store your full card number.
How we use it
We use your information to run the app, save your progress, keep your account secure, and send you messages about your account, such as a welcome note or a confirmation email.
Who we share it with
We share data only with the service providers that help run Winjitsu: our hosting and database provider, our email provider, and our payment provider. We do not sell your personal information.
Cookies and storage
We use a sign-in cookie so the app knows it is you, and we store your progress so it is there when you return. We do not use advertising trackers.
Your choices
You can view and update your name in your account, and you can ask us to correct or delete your data. To make a request, email info@ricktew.com.
Children
Winjitsu is not directed at young children. If you believe a child has created an account, please contact us so we can remove it.
Changes and contact
We may update this policy as Winjitsu grows. If we make important changes we will let you know. Questions? Email info@ricktew.com.
