Terms
Last updated 12 October 2026
Fruit Fly Airlines is a free game and science toy, on the web at fruitflyairlines.com and as an app, made by Kekwanu Labs, LLC (“we”). By playing or buying something in it, you agree to these terms. The short version: playing is free, what you buy is for fun and never changes a score, you can cancel the Brain Lab any time, and if something goes wrong with a purchase, we'll put it right.
Playing
Anyone can play, free. Please play fair: no bots, scripts or tampering to get onto the world board, and no names on the board that are rude, hateful or pretend to be someone else. We remove scores and names that break this, and can stop someone from posting to the board.
What you can buy
- Hangar items (fly skins, brain colours, trails, boarding-pass designs): looks only. Nothing you buy changes how the fly flies or what you score.
- Frequent Flyer: one payment for every Hangar item you can buy, now and later, and the First class pass. It doesn't include the Brain Lab or items you earn by playing.
- The Brain Lab: a subscription (below) for three brains to train and every experiment, any time. One experiment a day is free without it.
- Adopt a neuron: your chosen name shown on one neuron of the fly's brain, for everyone who taps it. It's symbolic: you don't own the neuron, the data or anything else. Names must follow the same rules as the world board; we remove names that don't, and give you a chance to choose another.
- Tips: a thank-you that helps run the game. A tip doesn’t unlock anything for play; as thanks, the fly eats what you send and your passport gets a Supporter stamp.
What you buy is a licence to use it in the game, for as long as the game runs. It has no cash value and can't be sold, swapped or transferred. You can also unlock most Hangar items with Miles, earned by playing.
Where you pay
On the website, payments go through Stripe, in US dollars. Paying signs you in with the email you paid with: that's your account, and it keeps what you bought, in any browser and in the app. In the iPhone and iPad app, you pay Apple, Apple's terms apply to the payment, and purchases stay with your Apple ID (Hangar › Restore brings them back). Prices are shown before you pay.
The Brain Lab subscription
The Brain Lab costs the price shown when you subscribe (at the time of writing, $2.99 a month or $19.99 a year) and renews automatically at the end of each month or year until you cancel. We'll tell you before a price changes, and a new price applies only from your next renewal.
Cancelling: on the website, Menu › Settings › Account › Manage or cancel the Brain Lab. In the app, in your Apple ID's subscriptions (Settings › your name › Subscriptions). When you cancel, you keep the Brain Lab until the end of the time you've paid for; it then stops, and nothing more is charged.
Refunds
Bought on the website: if something doesn't work, or you bought it by mistake, email hello@fruitflyairlines.com within 14 days and we'll refund it. For the Brain Lab, that covers the latest payment within 14 days of it. Where the law where you live gives you more, you get that too.
Bought in the app: Apple handles refunds: ask at reportaproblem.apple.com.
Your account
Your account is your email address, with no password: to sign in elsewhere, we email you a code. Keep your email account safe, since anyone who can read it can sign in. You can delete your account any time, in Settings › Account; what you bought on the website goes with it and can't be restored. How we handle your data is in the privacy policy.
Changes, and if the game ends
The game is a work in progress: features, cities and items change. If we ever close it, we'll say so in the game at least 30 days ahead, stop selling, and stop renewing subscriptions. We can change these terms; the date at the top will change, and if a change matters for something you've paid for, we'll tell you in the game first.
The science
The fly's brain is a model built on real research data (credited in the game, under What's real). It's for curiosity and fun, not for research or medical use, and nobody knows what a real fly is thinking.
The legal part
The game is provided as it is. We work to keep it running, but can't promise it will always be available or free of bugs. As far as the law allows, we aren't liable for indirect losses, and our total liability to you is limited to what you paid us in the 12 months before a claim. Nothing here takes away rights you have by law as a consumer. These terms are governed by the laws of the State of Washington, USA.
