How Jellytone handles your data

Last updated: 7 September 2026. This policy covers the Jellytone app specifically, which is currently in beta testing. For our general website privacy policy, see here.

The short version

Jellytone has no accounts and no sign-up. The game itself works offline. There are no ads, no advertising networks, and nothing that follows you across other apps or websites. Your saved game — every star, every unlocked map — lives on your device and is never uploaded to us or synced anywhere.

While Jellytone is in beta, the app does send usage data, so we can see which parts of the game people play and where they stop. There is no name, no email, and no account attached to it. It is not perfectly anonymous either, and we would rather say so than lean on the word. It is described in full below, because "anonymous" is a word worth being specific about.

What's stored on your device

The game keeps your progress locally. This save file is never uploaded to us — though, as the next section explains, usage events do tell us roughly how far players get in general.

• Which levels you've completed, your star ratings, and which chapters and maps you've unlocked
• Which instrument journey you're on — piano, guitar, or bass — and the separate progress for each
• Your Daily Jam results
• Your scores, app settings, and preferences

This stays on your device until you delete the app. Deleting removes it — though if you back up your iPhone, a copy may live on inside that backup, which is yours and not ours.

What leaves your device

Jellytone uses PostHog, a product-analytics service, to answer questions like which modes people play, how far into a journey they get, and where they stop. That is the whole purpose. We are not building a profile of you, and we have nothing to sell.

It is here for the beta. Those are beta questions — they decide what gets built and when the game is finished — and the intention is to take PostHog out when Jellytone leaves testing. That is a plan rather than a promise, and this page will be updated to describe whatever actually ships.

What travels with each event:

• A random identifier generated on your device the first time you open the game. It is not your name, your email, or your Apple Account. It does persist, though — so repeated sessions from the same installation look to us like the same returning player. That is how we can tell whether people come back.
• Basic technical details — things like device model, iOS version, app version and build, screen size, language, and time zone.
• In-app events — which screens you opened; when the app was installed, updated, started, or sent to the background; and what happens in play, such as which mode and level you started, whether you finished it, and where you stopped.
• Your IP address, which PostHog receives as part of any internet request. It is stored alongside each event and used to derive an approximate location — country, state, and usually the nearest city. This is not GPS, it does not follow you around, and it is accurate to a city at best. It is still worth naming rather than glossing over.

Taken together, that is not anonymous data in the strict sense — a persistent identifier plus an IP address counts as personal data under laws like the GDPR, even though we have no idea who you are and no way to find out. We would rather tell you that than call it anonymous and hope you don't look.

PostHog Inc., a United States company, holds this data as our processor, on our behalf and on our instructions, under their privacy policy. We do not sell it, share it with advertisers, or hand it to anyone else. If you are in the UK or the EU, we process it on the basis of our legitimate interest in understanding how the game is played and making it better, and you can object at any time by writing to us.

Two things worth stating plainly. Jellytone does not record your screen or your interactions — PostHog is capable of session recording and we have it switched off. And we never attach a name, an email address, or an account to any of this, because the app doesn't have any.

Deleting the app clears the random identifier. A fresh install generates a new one, and we have no way to connect the old events to the new ones.

What we never collect

• Your name, email address, or any account — there is nothing to sign up for
• Your precise or GPS location
• Your contacts, photos, calendar, or microphone
• Anything we could sell — there is no buyer, no broker, and no ad network in this app

Jellytone shows no app-tracking permission prompt, because it does nothing across other companies' apps or websites that would require one.

Crash reports

We don't collect crash reports. There is no crash-reporting service in the app. If Jellytone crashes, the most useful thing you can do is email us and say what you were doing.

Purchases

There is nothing to buy in Jellytone today. If that ever changes, purchases would be handled entirely by Apple — we would never see or store payment information — and this policy would be updated before it happened.

While Jellytone is in beta

The beta runs through Apple's TestFlight, which has its own privacy terms covering how Apple handles testers. If you joined through the public link on our site, you are anonymous to us — we see a count of testers, not who they are.

If you send feedback from inside TestFlight, Apple passes it to us and may include your device model, iOS version, and a screenshot if you attach one. If you email us instead, we have whatever you chose to put in that message, used only to write back to you.

Children's privacy

Jellytone's content is suitable for children — there's no chat, nothing other players can post, and no links out of the game. But the app is made for adults, it isn't directed at children under 13, and we don't knowingly collect personal information from them. If you believe a child has provided us with personal information, email us and we'll delete it.

How long we keep it

Usage events stay in PostHog for no longer than twelve months, and we delete them sooner once they've answered the question they were collected for. Emails you send us we keep while the conversation is live, and delete on request.

Your choices and your rights

Deleting the app removes everything stored on your device and retires the random identifier for good. That is the surest way to stop the app sending anything.

Depending on where you live, you may have rights over personal data under laws such as the GDPR or the CCPA — to see what's held about you, to correct it, to have it deleted, or to object to it being collected at all. Write to us and we will honor those requests as far as we're able. One honest limitation: because the usage data carries no name, email, or account, we usually cannot tell which events came from you. If you can send us the random identifier, we can find and delete the events attached to it.

The data sits in PostHog's systems, encrypted in transit and at rest, and the only person who looks at it is the one person who runs this studio.

Changes to this policy

We'll update the date at the top of this page if this policy changes, and post the revised version here.
