Privacy Policy

Effective date: October 9, 2026

The most important thing first: Zazti never uploads and never keeps any video or image of the players. The camera is processed entirely on your own device. The only thing it holds on to is a highlight: while a round plays, your device keeps a few seconds of it in memory, so a grown-up can share them at the end if they want to. That clip is never sent to us or anyone else, and it's deleted when the next round starts or you leave.

Zazti (zazti.com) is a free, browser-based motion game platform made for families with kids ages 3 and up. Because our players are kids, we built Zazti to collect as little as possible. This page explains, in plain language, exactly what that is.

The camera: it stays on your device

• Zazti games use your device's camera so children can play by moving their bodies.
• All motion detection runs locally on your device, inside your web browser or the Zazti app.
• The camera feed is never uploaded, never stored on our servers, and never sent, not to us, not to anyone.
• Highlight clips. During a round, your device keeps its liveliest few seconds (up to 6) in memory, with the game's music, so they can be shared from the results screen. Sharing needs a grown-up to press and hold first, and the clip then goes only where you send it, through your device's own share menu. If no one shares it, it's deleted when the next round starts or you leave the game. In the Android app, a clip you share is written to the app's private storage for the share menu to read, and deleted the next time you play or open the app.
• We do not collect biometric identifiers. The body-position data ("pose landmarks") computed during play is processed on your device and discarded; it is not sent to our servers.

What we do collect, and why

• A nickname and avatar emoji that the player chooses, used to show their profile and scores. Please use a made-up nickname, not a real full name.
• A random device token: a randomly generated code stored on your device. It contains no personal details and is not linked to any identity. We use it so the same device can keep its saved profile, scores, and achievements.
• Game data: scores, achievements, difficulty, and session information (which game was played and for how long), linked only to the random device token.
• Anonymous usage counts: we count events like "a game was started today" as plain daily totals, including coarse device type (phone, tablet, or computer), country-level visit totals, and the general kind of place a visit came from (for example "a search engine" or "direct") — never full web addresses. These counts contain no identifiers of any kind. We can see that a game was played 100 times, but not by whom.

We use this information only to run Zazti: saving progress, showing scoreboards, keeping games fair, and understanding which games kids enjoy. This is the "support for internal operations" of the service. It is never used to contact anyone, build a profile of any individual, or show advertising.

What we don't do

• No advertising of any kind: no ads, no ad networks, no behavioral targeting.
• No third-party analytics SDKs (no Google Analytics, no Firebase, or similar).
• No selling, renting, or sharing of data with third parties.
• No accounts, emails, phone numbers, locations, or contact lists. We never ask for them.
• No social features with strangers. Multiplayer means kids playing together in front of one camera.

Service providers

Zazti is hosted on Cloudflare (content delivery and serverless storage). Like any web host, Cloudflare processes IP addresses transiently to deliver the website and protect it from abuse (for example, rate limiting). We do not store IP addresses with any game or profile data. Cloudflare also provides us cookieless, aggregate page statistics with no persistent identifiers.

Data retention and deletion

• Profile, score, and achievement data expires from our servers automatically about 24 months after it was last saved. Playing refreshes it, so active players keep their scores and inactive data deletes itself.
• Anonymous usage counters are deleted automatically after about 13 months.
• You can delete everything saved for your device right now on the Delete My Data page, or with the "Remove my scores" button on the scoreboard.
• Settings and progress stored on your own device (browser local storage) can be cleared at any time through your browser settings.

Questions, issues, or deletion

You can delete your device's saved data yourself on the Delete My Data page. For anything else, including reviewing your child's data or deleting it for a device you no longer have, contact us at privacy@zazti.com and we'll take care of it promptly. Deleting saved data never affects the ability to play.

Changes to this policy

If we ever change what we collect or how we use it, we will update this page and its effective date before the change takes effect.
