Privacy

Last updated 12 October 2026

Fruit Fly Airlines is a free game and science toy at fruitflyairlines.com, made by KekwanuLabs. This page says what we keep about you, why, and how to have it removed. The short version: we keep very little, we never sell it, and there are no cookies.

Kept only on your device

Your scores, the name you type, your passport stamps, which city facts you've seen, and your settings are saved in your browser's local storage. They never leave your device unless you choose to put a score on the world board. Clearing your browser's site data deletes them.

When you fly

So that scores can't be faked, our server gives each flight its route and weather, and when the flight ends your browser sends the moments you tapped. The server re-flies the run to check the score. We don't store runs: nothing is kept unless you name the score (below).

How the game is played

To see how the game is doing and make it better, the game and the apps send a few events to PostHog, our analytics service: when it opens, when a flight starts and ends (the mode, how far it got, the city and how it ended, and how smoothly the game ran), when you share and which app you share to, and errors. Each comes with a random ID made on your device, the kind of device, its screen size and the name of its graphics chip (so we can make it run well on older computers), and the app version. PostHog works out your country from your IP address. Nothing tracks you across other apps or sites, and we never sell or share it. You can turn it off in the game's Settings.

Public: the world board and the Hall of Fame

If you save a score, the name you type goes on the public world board with the score, the number of cities and countries, the flight time, the city that got your fly, and the date. If your fly makes it around the world, the same name and your time go in the Hall of Fame. Use any name you like; it doesn't need to be your real one. Names are checked for slurs and obscenities, and we may hide any name.

Shared boarding passes

When you open the share sheet, your boarding pass (the picture, the share line and the city) is uploaded so that the link you post can show it. Anyone with the link can see it. We also keep the IP address that uploaded it, to stop abuse.

Email updates

If you sign up for updates, we keep your email address, where on the site you signed up, when, and your IP address (to stop abuse). We send one email asking you to confirm; until you do, we send nothing else, and if you don't, we delete the address after 30 days. We use your email only to send news about Fruit Fly Airlines. Every email will have a link to unsubscribe, and you can also just email us. We never sell or share your address, except with the service that sends the emails for us.

Buying, and your account

On the website, payments go through Stripe: you pay on Stripe's page, and we never see or keep your card. We keep what you bought, when, and the email address you paid with, which is your account: there's no password. To sign in elsewhere (another browser, or the app), we email you a 6-digit code; we keep it, scrambled, for 10 minutes, with your IP address to stop abuse. In the iPhone app, purchases go through Apple and stay with your Apple ID; we only see a receipt when you adopt a neuron. Delete your account any time from Settings › Account: what you bought on the web is forgotten (Stripe keeps its own payment records, as the law requires).

Other services

• Cloudflare hosts the site. Like any web host, it sees your IP address and browser with each request, and keeps short-lived logs (a few days) so we can fix problems. We use Cloudflare Web Analytics to count visits: it uses no cookies and builds no profile of you.
• PostHog (in the US) receives the events above.
• Stripe takes payments on the website, and Resend sends our emails (sign-in codes, confirmations).
• Google Fonts supplies the typefaces, so your browser asks Google for them.
• Open-Meteo supplies the weather. Our server asks for it, not your browser, so it never sees you.

Your camera and microphone

A few modes can use your camera or microphone so the fly can see and hear you. That happens entirely on your device: nothing is recorded or sent anywhere, unless you save a clip yourself.

Children

Anyone can play. Email updates are for people 13 and over; if you're younger, please don't sign up. If you think a child has given us their email, tell us and we'll delete it.

Your data, your call

Email hello@fruitflyairlines.com to get a copy of what we hold about you, or to have it deleted: your email address, your account and what it bought, a name on the board, or a shared boarding pass. We'll do it within 30 days.

If this page changes, the date at the top will change with it. What you can buy, renewals and refunds are in the terms.
