Privacy Policy

Last updated: April 2026

Who We Are

Fast-Zero-Cross is a mental fitness game created by Culture Awareness (culture-awareness.org). This policy explains what data we collect and how we use it.

What We Collect

• Email address — used to create your account and send your verification code.
• Password — stored as a one-way hash (PBKDF2, 100,000 iterations). We never see or store your actual password.
• Leaderboard submissions: When you submit a score to the World Top 100 leaderboard, we store the name you enter, your score, game mode, and time taken. We also store your IP address for rate limiting purposes.

What We Do Not Collect

• No analytics or tracking
• No cookies (beyond what is essential for login)
• No advertising identifiers
• No location data
• No device fingerprinting

How We Use Your Data

• Leaderboard names and scores are displayed publicly on the World Top 100 leaderboard.
• IP addresses are used solely for rate limiting to prevent abuse. They are not shared or sold.
• Data is stored for the sole purpose of allowing the World Top 100 Leaderboard to function.

Your Data is Not for Sale

We do not sell, rent, or share your data with any third party. Privacy is taken seriously. Your data exists only to support your account and the leaderboard and is never used for any other purpose.

Payment

Payment is handled entirely by Stripe. We never see, store, or process your card details. Stripe's own privacy policy governs how they handle your payment information.

Data Storage and Retention

Your account and leaderboard data is stored on a secure server in the EU. Data is encrypted in transit via HTTPS and at rest where supported.

We retain your account data only while your account is active. You can request deletion at any time through the in-app Account settings or by emailing us — see below. Leaderboard entries are anonymised (only a display name you choose is shown publicly) and retained for comparison purposes.

Stripe retains payment records separately under its own retention schedule, as required by financial regulation.

Your Rights

• You can request deletion of your account and all associated data at any time by contacting us.
• We will delete your data within 30 days of the request.
• You can use the game without submitting any data to the leaderboard.

Children

This game is suitable for all ages (4+). We do not knowingly collect personal information from children under 13. Leaderboard submission is optional and requires only a display name.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated date.
