One Line Escape

No email, no password, no profile. Your progress stays on your phone. The one thing that leaves it is the leaderboard: your points and a name — a random one until you change it — kept on the game’s own server. Google is involved in two places: ads you tap to watch for extra hints, and purchases.

There is nothing to sign up for. Your progress, your hints and the accessibility options you pick (things like reduced glow, reduced motion, higher contrast) are saved on your phone only, and they disappear when you uninstall the game. They are never uploaded, backed up, or shared.

The one exception is the leaderboard. That is the next section.

The game has one leaderboard, ranked on points: a point for every line you finish, and a second for every one you finish perfectly. It runs on the game’s own server.

What is sent, and when. The first time the game starts, it signs in to the server anonymously — no email, no password, nothing you type. That makes an anonymous player id for this phone — a random code, tied to nothing about you — and a session, so the server knows this phone again next time. The game also gives you a random name, like Swift Lynx 61. Once you finish your first line, the leaderboard keeps a row of three things: that id, the name, and your best points total. Other players see the name and the total; nobody sees the id.

What the server sees. Like any website, the server sees your internet address when the game talks to it. It keeps that address, and the country it points to, with the session and in its logs. It is not used for advertising and not shared with anyone.

Where it runs. The leaderboard runs on Appwrite, open-source server software, on the game’s own server. No other company hosts it or sees what is on it.

What it does not need. No account, no email, no sign-in. The whole game works without a connection — every level, the daily challenge, hints, rewards, and your own points total, which is worked out on your phone and shown on the leaderboard screen either way. Offline, the board simply waits until you are back.

The name is yours to change. Keep the random one, or pick anything else on the leaderboard screen — your real name only if you want it there.

Removing it. Uninstalling leaves your row on the board under its name, and the anonymous account behind it, but nothing ties either to you. To have them removed, write to the contact address below with the name and points total the board shows, and both are deleted.

There are two one-time purchases: the last world, and unlocking every level inside a world you have already opened. Both go through Google Play, which takes the payment — we never see your card details or your address, and none of that reaches the game. What the game asks Google is whether this account owns the purchase, so that what you paid for is there on this phone and on your next one.

The game offers an ad in exactly two places, and never shows one on its own: a “watch an ad for +2 hints” button on the victory screen, and the same offer when you tap an empty hint slot. You have to tap it yourself. There are no banner ads and no ads between levels.

Those ads come from Google AdMob. To show them and count them, Google collects your device’s advertising ID and what you do with the ad, under Google’s own privacy policy: policies.google.com/privacy. We never see or store any of it — it goes straight to Google. You can reset your advertising ID, or turn off personalised ads, in your phone’s Google settings whenever you like.

Asking first. For players in the EU, EEA and UK, the game asks your permission before it loads any ad at all, and asks whether personalised ads are alright. You can change your answer later under Settings → Privacy settings, which only appears where your region requires it.

The game asks your phone for three things: internet access, for the ads, the purchases and the leaderboard; permission to show notifications, for the optional daily reminder (Settings → Daily reminder — on by default, one tap to turn it off); and permission to set that reminder again after you restart your phone, so it does not quietly stop. None of them send anything anywhere — the reminder is made and shown on your own phone. The game asks for nothing else: no camera, location, contacts, files or microphone.

One Line Escape is not aimed at children and is rated for ages 13 and up. We do not knowingly collect data from children. The leaderboard keeps only a name, random unless the player types one, and a points total; the purchases run on a Google account, which has its own age rules and its own parental controls — set in Google Play, not here.

If what the game collects, or which other companies are involved, ever changes, this page is kept in step with it. The date at the top is the date of the last change.
