PiVille privacy policy
Last updated: 6 November 2026
PiVille is a math game for kids. We collect as little as we can, we never show ads, we never sell or share data for advertising, and we don't use third-party analytics or tracking.
What we keep, and why
- The hero. The name the kid picks for their hero, how the hero looks, their house, apartment, furniture and clothes, their Pi (the game's points, not real money) and which parts of the tutorial they finished. This is the saved game, so it isn't lost and can be loaded on another device.
- A device key. A random code kept in the device's Keychain that lets the game sign in to its hero without a password. We keep only a scrambled copy.
- A grown-up's email, only if a grown-up adds one. Behind a grown-up check, a parent can save the hero to their email to bring it to a new device. We use it only to send the 6-digit codes for that. Kids are never asked to type an email.
- Playing with friends. Friends and friend requests, battles between friends and their results, and messages between friends. Messages are only ready-made phrases (like "Good game!") and battle invitations; kids can't type their own words. Kids can block and report other heroes; a report keeps the reported name and the last messages between the two so we can check it.
- How the game is used. Which days a hero played, battles won, and right and wrong answer counts, so we can see whether the game works and fix what doesn't.
We don't collect real names, photos, contacts, location, or advertising identifiers. The game doesn't ask for the camera, microphone or photos.
Who can see it
Other players see a hero's name, look and house, and friends can visit it. Nobody but us sees a grown-up's email. Our servers run on Cloudflare, which processes the data for us and only on our instructions. We don't give data to anyone else unless the law requires it.
Deleting a hero
In the game: open My Hero, choose Delete hero, pass the grown-up check and confirm. This deletes the hero and everything above from our servers right away, and the grown-up's email too when no other hero is saved to it. You can also email us at privacy@piville-game.com and we'll delete it for you. Some anonymous battle counts, with nothing that leads back to a person, stay in our statistics.
Children
PiVille is made for children. A parent or guardian can ask us at any time to see or delete what we have about their child, or to stop collecting it, by writing to privacy@piville-game.com.
Keeping it safe
Everything travels encrypted (HTTPS). Device keys and email codes are stored scrambled, and email codes expire after 10 minutes.
Changes
If this policy changes, we'll update this page and the date above. Important changes will also be shown in the game.
