We're a small studio, and we take privacy seriously — both yours and ours. This policy explains what data we collect, why, and how to get rid of it whenever you'd like.
01What we collect
We collect only what we need to sell you a cube, send you a puzzle, and let you sign in again next month.
- Account information — name, email, and a hashed password (we never see the plain version). Stored in AWS Cognito.
- Order information — billing address, shipping address, and order history. Payment details are processed entirely by Stripe and never stored on our servers.
- Usage data — if you've opted in to analytics, we collect anonymous, aggregated information about how you use the site (page views, button clicks). No personal identifiers.
- Puzzle progress — if you sign in, we save your puzzles and times so you can resume from any device.
02What we don't do
- We don't sell your personal information. Ever.
- We don't share data with advertising networks unless you opt in to marketing cookies.
- We don't train AI models on your puzzles, messages, or behavior.
- We don't track you across other websites.
03How we use it
We use your information to fulfill your order, send you transactional emails (order confirmation, shipping, password reset), and — only if you opted in — send you the weekly puzzle newsletter.
We use anonymized analytics to understand what's working and what isn't. That data helps us make the site better. It never identifies you personally.
04Who we share it with
We share data only with the service providers we need to operate:
- Amazon Web Services — hosting, database, authentication (US, EU).
- Stripe — payment processing.
- Shipping carriers — to deliver physical products.
- Email providers — to send transactional and (opted-in) marketing email.
Each of these providers is contractually bound to handle your data securely. We never share your data with anyone else without your consent or a valid legal request.
05Cookies
We use a small number of cookies. The strictly necessary ones keep you signed in and your cart intact. Everything else is optional and off by default. See our cookie policy for the full list and to change your preferences.
06How long we keep it
We keep your account data for as long as your account is active. Order records are kept for seven years to comply with tax law. Anonymized analytics are kept indefinitely; personal analytics events are deleted after 26 months.
07Your rights
Wherever you live, you can ask us to:
- Access the personal data we hold about you.
- Correct anything that's wrong.
- Delete your account and personal data.
- Export your data in a portable format.
- Object to certain uses (e.g. analytics) by changing your cookie preferences.
If you're in the EU, UK, California, or any jurisdiction with a privacy law, you have these rights guaranteed. Email privacy@zudocube.com and we'll respond within 30 days.
08Children
ZudoCube is suitable for puzzlers of all ages, but accounts are only available to people 13 and older. If you believe a child has signed up, contact us and we'll close the account.
09Changes to this policy
If we make material changes to this policy, we'll email you and post a notice at the top of the site. The date at the top of this page is always the date of the latest revision.
