Atlas: Reasoning Edge · last updated 24 September 2026

Atlas has no accounts and asks you for nothing. No sign-up, no advertising, no tracking, and a case can be played with no network at all. The one thing we ever receive is your answer to the question after a case, if you choose to give it — and it carries nothing that identifies you.

What the app stores, and where

The app keeps two things, and both of them belong to you rather than to us:

• Your progress — which cases you have finished, the guesses you made and how close they were, plus any case you are part-way through.
• Your settings — the light or dark theme, whether sounds are on, and the difficulty you chose.

Both are held on your device, in storage belonging to the app. Deleting the app, or using Reset progress, deletes them.

There is no account to make

Atlas has no sign-up, no sign-in and no password. We never ask for your name, your email address or anything else about you, and there is no screen in the app where you could give them. Your progress lives on your device and, if you use iCloud, in your own iCloud account — described below.

iCloud, if you use it

If you are signed in to iCloud, the same progress is also saved to your own iCloud account, so that picking up a second Apple device carries on where you left off. This uses Apple's iCloud key-value storage and happens automatically, with nothing to set up.

EdgeCraft cannot see any of it. The data goes to Apple, into storage locked to your Apple Account. We operate no server, we hold no key or password that would open it, and there is no dashboard anywhere in which your progress appears. That is not a promise about how we behave — there is simply no route by which it could reach us.

What travels is your game progress and your settings, and nothing else: no name, no email address, no location, no contacts and no identifier that describes you. Apple's handling of what is in your iCloud is governed by Apple's privacy policy rather than by this one.

If you are not signed in to iCloud, or you turn iCloud off for Atlas, the app works exactly as it otherwise would. Nothing is synchronised, nothing is lost, and nothing about the game changes.

The question after each case

When a case ends, Atlas asks which clue gave it away. Answering is one tap and entirely optional — you can go straight on.

If you answer, we record which clue you chose for that case, so we can show everyone what most players found decisive and write better cases. We do not record who gave which answer. The stored response carries no account id and no device id — only a one-way code that lets us count one answer per person per case, and which we cannot turn back into you through any part of the app or its API.

To be precise rather than flattering: this is pseudonymous rather than anonymous. Nobody can look up your answers, and there is no account to tie them to in the first place — but we do not claim the link is mathematically impossible. What we keep is a count of which clue solved a case.

What is never attached to an answer: your name, your email address, an Atlas account (there is none), an advertising identifier, or any identifier belonging to your device or your copy of the app.

What our hosting provider sees, which we should not pretend away. Sending anything over the internet means a server receives the request, and with it the ordinary metadata every web request carries — including your IP address and the version of the app making the call. Our host processes that to deliver the request and to keep the service from being abused. It is not written onto your answer, and we do not keep a log of it: where we need it to stop one machine manufacturing thousands of votes, we immediately convert it into a one-way code scoped to a single hour, store only that code, and delete it within two hours.

How long things are kept. Survey answers and gameplay records are kept for as long as the app uses them, which is indefinitely: they carry nothing about you, and the counts they form are the feature. Error reports are kept for 90 days. The abuse-prevention codes described above are deleted within two hours.

How the game is used

Atlas records what happens in a case — that one was opened, which clue was looked at, whether the suspects were asked for, how the answer was given and whether it was right, and where somebody stopped if they stopped. It is how we learn which cases are too hard and where the game loses people.

None of it is attached to you. There is no account, and these records deliberately carry no name for your device, your install or you — not even the private one the app uses to remember your progress, or the one it uses to count survey answers. Two sittings by the same person cannot be recognised as the same person, by us or by anybody.

What does travel with them is a reference for the sitting itself, invented when the app opens and forgotten when it closes, so that a handful of events from one session can be read as one session. The next time you open Atlas it is a different one, and nothing can connect the two.

When something breaks

If the app hits an error, a report is sent describing what went wrong and where in the code — the message, the technical trace, and the version you are running. It carries no account, no name and nothing you typed.

This one is handled for us by Sentry, a company whose only business is collecting error reports for software. Because the report travels over the internet, Sentry receives the IP address it came from; we have configured the project so that address is discarded rather than stored. Reports are kept for 90 days.

What the app does not do

• It has no accounts, no sign-in and no password.
• It does not ask for your name, email address, age, gender, phone number or address.
• It does not use any advertising, marketing or measurement code.
• It does not read your location, camera, microphone, photos, contacts or calendar.
• It does not use cookies for tracking, and shows no advertisements.
• It does not track you, and it asks for no tracking permission, because there is nothing to track.
• It contacts no server while you play a case. Its maps are drawn from geometry built into the app rather than fetched from a tile service, and every photograph is a file inside the app. The only connection Atlas ever makes is to send your answer to the question after a case, if you give one.

Other companies

There is no advertising or marketing code inside the app, no embedded trackers, and no data sold or shared with anyone for their own purposes. Two companies receive anything at all, both on our instruction and neither free to use it for themselves.

Supabase hosts the survey answers and the gameplay records described above.

Sentry receives the error reports described above, and nothing else.

Apple is involved in getting the app to you and, if you use iCloud, in storing your progress in your own account — and sees only what it would see for any app. If you installed Atlas from the App Store or through TestFlight, Apple records the download and, if you have agreed to it with Apple, may share aggregate statistics such as crash counts. All of that is governed by Apple's privacy policy, not this one. If you are using the version on the web, the host serving the page records ordinary web server logs, and no iCloud synchronisation happens at all.

Families

Atlas is a general-audience educational app rather than a product designed for children. It contains no adult content and families are welcome to play it together. Because it collects no personal information from anyone, it collects none from younger players either.

Deleting your data

Reset progress, on the Profile screen, deletes everything — on that device and in whichever cloud is holding it, including on your other devices. It cannot be undone. Deleting the app removes the copy on that device; signing out of iCloud, or turning iCloud off for Atlas, stops anything further being saved there.

Survey answers cannot be removed on request, because there is no way to find yours: nothing on them identifies you, which is the same property that makes them safe to give.

We hold nothing that is about you — no account, no email address, no profile — so there is nothing to request, export or have erased, and equally nothing we could restore.

Changes

If a future version of the app ever collects or transmits anything else, this page will be updated before that version is released, and the date at the top will say when.
