Privacy Policy
Last updated: February 6, 2026
This Privacy Policy explains how ∞ Tango Unlimited ("8tango", "we", "us", or "our"), operated at 8tango.com, collects, uses, and protects your information when you use our website and services.
1. Information We Collect
1.1 Account Information
If you create an account (to sync progress across devices or purchase Premium), we collect your email address. Authentication is handled by Supabase, which stores a hashed session token and user identifier. We do not store passwords — sign-in is via magic link (one-time email code) or third-party OAuth (e.g., Google).
1.2 Purchase Information
If you purchase Premium, payment is processed by Stripe. We receive a confirmation of payment, a Stripe checkout session ID, and a payment intent ID. We do not store your full credit card number, CVV, or billing address. Stripe's privacy policy governs how they handle your payment data: stripe.com/privacy.
1.3 Game Data
We store your game progress, statistics (puzzles solved, best times, achievements), display name, and avatar selection. For logged-in users, this data is synced to our server so it persists across devices. For anonymous users, this data is stored locally in your browser's localStorage.
1.4 Automatically Collected Data
- Google Analytics — we use Google Analytics (measurement ID: G-S3YR52J476) to understand aggregate usage patterns (which pages are popular, session duration, device types). Google Analytics uses cookies and may collect your IP address, which Google anonymises. Learn more: How Google uses information from sites that use our services.
- Server logs — our hosting provider may collect standard web server logs (IP address, request URL, timestamp, user agent). These are used for security and debugging and are not shared with third parties.
1.5 Advertising Data
For non-Premium users, we may display ads using Google AdSense. Google and its advertising partners may use cookies or similar technologies to serve and measure ads based on your browsing activity. You can control ad personalisation in your Google Ads Settings.
Premium users do not see ads and we do not load the AdSense script for them.
2. How We Use Your Information
- To provide, maintain, and improve the game experience.
- To authenticate your account and sync progress across devices.
- To process Premium purchases and manage entitlements.
- To display relevant ads (non-Premium users only).
- To analyse aggregate usage for performance improvements.
- To respond to support requests.
3. Cookies and Local Storage
We use cookies and browser localStorage. For a detailed breakdown, see our Cookie Policy.
4. Third-Party Services
- Supabase — authentication and database (stores account data, game stats, entitlements).
- Stripe — payment processing for Premium purchases.
- Google Analytics — anonymous usage analytics.
- Google AdSense — advertising for non-Premium users.
- Render — web hosting.
Each third-party service operates under its own privacy policy. We encourage you to review them.
5. Data Retention
We retain your account data and game statistics for as long as your account exists. If you delete your account, we will delete your personal data within 30 days, except where we are required by law to retain it (e.g., payment records for tax purposes).
6. Data Security
We use industry-standard security measures, including HTTPS encryption for all connections, secure authentication tokens, and role-based access controls for our database. No system is perfectly secure, but we take reasonable steps to protect your information.
7. Your Rights
Depending on your location, you may have the following rights:
- Access — request a copy of the personal data we hold about you.
- Correction — ask us to correct inaccurate information.
- Deletion — ask us to delete your personal data.
- Objection — object to certain types of processing (e.g., personalised advertising).
- Portability — request your data in a structured, machine-readable format.
To exercise any of these rights, email [email protected].
8. Children's Privacy
8tango is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it.
9. GDPR (European Users)
If you are in the European Economic Area, our legal basis for processing your data is: (a) your consent (for cookies and analytics), (b) contractual necessity (for account and purchase data), and (c) legitimate interest (for security and service improvement). You may withdraw consent at any time by adjusting your privacy preferences or contacting us.
10. CCPA (California Users)
If you are a California resident, you have the right to know what personal information we collect and to request its deletion. We do not sell personal information. To make a request, email [email protected].
11. Changes to This Policy
We may update this Privacy Policy from time to time. If we make material changes, we will update the "last updated" date at the top and, where appropriate, notify you via the game interface or email.
