Privacy Policy

ALVAN ("ALVAN", "we", "us") is a project of Algoy.com. We build free virtual-reality and mixed-reality (WebXR) games that run in your headset's web browser at alvan.algoy.com. This policy explains what limited data our games use and why. By playing our games you agree to this policy.

1. Information we collect

• A random player alias. The first time you play, your game generates a random nickname (for example Agent-4F2A). It is stored in a cookie named alvan_player on the .algoy.com domain and in your browser's local storage, so your identity stays the same across our games. You can change or clear it any time (see "Your choices").
• Leaderboard scores. When you finish a round, we save your alias, your score, and a timestamp to our database so leaderboards work. We do not attach your real name, email, or precise location to these entries.
• Local game data. Your best scores and preferences are stored locally in your browser (local storage) and never leave your device unless used for a leaderboard submission.
• Usage analytics. We use Google Analytics 4 to understand aggregate, largely anonymized usage — things like device/browser type, approximate region, which games are opened, and general interactions. This uses cookies and similar technologies.

2. What we do NOT collect

• No names, email addresses, or phone numbers (unless you choose to email us).
• No payment information — our games are free.
• No camera, room-scan, or passthrough data. Mixed-reality passthrough is rendered by your headset and stays on your device; we never receive it.
• No precise GPS location.

3. How we use information

We use the limited data above to operate cross-game leaderboards, keep your alias consistent, fix bugs, and understand which games people enjoy so we can improve them and build more.

4. Cookies & local storage

We use: the alvan_player cookie (your alias), Google Analytics cookies (usage measurement), and browser local storage (alias and best scores). You can clear cookies and local storage at any time through your browser settings; doing so simply resets your alias and local scores.

5. Third-party services

We rely on a few trusted providers who may process data on our behalf:

• Google Analytics (usage measurement) — see Google's Privacy Policy.
• Supabase (database/hosting for leaderboards).
• Your headset's browser (e.g. the Meta Quest Browser) and the open-source Three.js library used to render the games.

6. Data retention

Leaderboard entries are kept until you ask us to remove them or we retire a game. Analytics data is retained according to Google's settings and policies.

7. Your choices & rights

• Clear your cookies and browser local storage to reset your alias and local scores.
• Ask us to delete your leaderboard entries by emailing support@algoy.com with your alias.
• Use your browser's "Do Not Track" or analytics opt-out tools if you prefer not to be measured.

8. Children

Our games are not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us information, contact us and we will remove it.

9. Changes to this policy

We may update this policy as our games evolve. We'll revise the "Last updated" date above when we do.
