Hey, Paddle Pro!

No sign-up, no account.
No login, no password, no email required. Just open and play.

No personal information collected.
We never ask for or collect your child's name, email, address, phone number, photos, or location.

Everything stays on your device.
Mission progress and badges are saved only in this browser, on this device. They are never uploaded to a server, and the optional certificate name you type is used only to draw the image on your device — it is not sent anywhere.

No ads. No third-party trackers. No data selling — ever.

Anonymous play analytics.
We measure five simple, anonymous events — app opened, mission started, mission completed, a help topic opened, and player count — to see which missions work and where kids get stuck. Every event is just an event name plus, at most, one small value (a mission number, a help topic, or a player count). We never attach a name, account, IP address, device ID, or any other identifier to this data. This is measured using our own infrastructure (not a third-party analytics service) and stored for 90 days, then automatically deleted.

No microphone, ever.
JUMVI never asks for microphone access and never records audio. The only sound JUMVI produces is optional read-aloud text, generated by your device's own built-in voice (the browser's text-to-speech) — it plays out loud but is never captured, saved, or sent anywhere.

COPPA & children's privacy.
This app is designed to align with the U.S. Children's Online Privacy Protection Act (COPPA). We do not knowingly collect personal information from children under 13. If you believe we have, contact us and we will address it promptly.

Play safely.
These missions involve real, active paddle play. Please provide adult supervision and play in a safe, open space clear of obstacles.
