Who is responsible

The controller of your data is:

What the game sends us: anonymous play statistics

To learn how the game plays (where runs end, which challenges are too hard, whether the looks are worth playing for), Latchline sends short gameplay signals to TelemetryDeck, an analytics service that processes them for us.

What a signal can contain:

• The game and your device, coarsely: the game's version, the kind of platform (for example iPhone, Android or browser), and a rough screen-size class and orientation. These are never the exact screen size or the device model.
• Your settings in the game: whether sound is on and whether the ghost is shown.
• How you play: when a session and a run start and end; a run's distance, score, district reached, how it ended, perfect releases, skips, sparks collected and duration; daily challenges completed; looks unlocked and chosen; your day streak and how many days since you first played; and when you press Share, mute or hide the ghost, or see a tutorial hint.
• An install ID. Once you say yes to anonymous stats, the game makes a random number and keeps it on your device. Signals carry only a salted hash of that number, never the number itself, and TelemetryDeck hashes it again when it arrives. The ID lets us count returning players without knowing who they are. It isn't your device's advertising ID, and it isn't linked to your name, email, account or any other app.
• A session ID, a fresh random number each time the game starts.
• The leaderboard, on Android: whether you're signed in to Google Play Games, and, when a score is posted, whether it went through and a rough band for your rank (for example 2 to 10, or 11 to 100). Never your Play Games name or ID, and never your exact rank.
• The leaderboard, on iPhone: whether you're signed in to Game Center, and, when a score is posted, whether it went through and a rough band for your rank (for example 2 to 10, or 11 to 100). Never your Game Center nickname or player ID, and never your exact rank.

What we never collect: your name, email address, phone number, contacts, photos, precise or approximate location (except at most the country, see below), advertising ID, or anything you type. The game has no accounts and no chat.

Like any server, TelemetryDeck sees your device's network (IP) address while it receives a signal. TelemetryDeck never stores IP addresses, not in its database and not in its log files. At most, it derives your country from part of the address. Signals are sent over an encrypted connection (HTTPS).

Why, and on what basis: to understand and improve the game. Our legal basis is your consent (Article 6(1)(a) GDPR). The first time you open the game, its title screen asks one short question: "Help improve Latchline with anonymous play stats?", with "Yes" and "No thanks". Until you answer yes, the game sends nothing and stores no install ID. If you play on without answering, nothing is sent and the game asks again the next time you open it; after three times without an answer it stops asking and treats that as no. The data cannot tell us who you are, and we never use it for advertising or sell it. You can withdraw your consent at any time with the Anonymous stats switch.

You can switch them off. Turn Anonymous stats off in Settings (the gear at the top of the screen). From that moment the game sends nothing, and it deletes its install ID and the day you first played. If you turn it back on, it makes a new ID that isn't connected to the old one.

Where and for how long: TelemetryDeck GmbH is based in Germany and processes the data for us under a data processing agreement. The data is stored only in the EU, on servers in Helsinki, Finland, and never leaves the EU. Anonymous signals have no fixed deletion date: TelemetryDeck moves older data to cold storage and expects to delete it after 7 to 10 years. Because the signals carry nothing that identifies you, they can't be traced back to you. TelemetryDeck's privacy policy: telemetrydeck.com/privacy

What stays on your device

These are kept only on your phone (or, in the browser version, in your browser's storage). We never receive them:

• your best scores (today's and all-time), your day streak, and a recording of your best run today, which the game replays as your ghost;
• today's challenge progress, your spark total and the looks you've unlocked and wear;
• your settings: sound, ghost, haptics and Anonymous stats;
• the install ID described above, and the day you first played.

Your progress (your bests, streak, today's challenge progress, sparks, looks, and which tutorial steps you've seen) is also saved in your own account, so it comes back after a reinstall or on a new phone: on Android in Google Play Games (Saved Games, when you're signed in to Play Games), and on iPhone in iCloud (when you're signed in to iCloud). On Android the same progress is also kept in one file that Android's own backup may include. These copies go only to Google or Apple, under their terms, to give you this feature (Article 6(1)(b) GDPR); they never go to our servers, and they never include the anonymous install ID, the day you first played, or your settings.

Uninstalling the game deletes all of it from your device; the copy of your progress in your Play Games or iCloud account stays there until you delete it in that account's settings. Reset progress in Settings deletes your bests, streak, challenge progress, ghost, sparks and looks, starts the copy in your account over too, and keeps your settings. On iPhone, your iCloud backup may include it, under Apple's terms. Android backups include only the progress file described above, never the install ID or your settings. When you press Share, the game puts a text summary of your result on your own clipboard. Where you paste it is up to you, and nothing is sent by the game.

The daily leaderboard (Android, Google Play Games)

On Android, Latchline has a daily leaderboard run by Google Play Games, Google's games service. It works only if you're signed in to Google Play Games on your phone. Signing in is optional: the game plays the same without it, and you can sign in or out in the Play Games settings at any time.

What the game sends, and to whom: when you're signed in, the game sends the score of your best run of the day (a run played in one go) to Google, with the date of that day's course. Google ranks it on the leaderboard and shows it to other players with your Play Games name and avatar, according to your Play Games profile settings. The game also asks Google for your rank, to show it next to your best score. Nothing about the leaderboard goes to our own servers: the game sends it only to Google.

Google's role: Google provides Play Games and its sign-in, and processes your Play Games profile and scores under its own terms and privacy policy: policies.google.com/privacy. Google's Play Games software in the game may also collect diagnostic information about how it works.

What stays separate: your Play Games name and ID never go to TelemetryDeck. The anonymous play statistics only say whether you're signed in and, after a score is posted, a rough band for your rank.

Why, and on what basis: to provide the leaderboard you chose to use by signing in to Play Games (Article 6(1)(b) GDPR).

Deleting your scores: Reset progress in the game doesn't remove scores that are already on the leaderboard. You can delete your Play Games data, scores included, from your Play Games profile settings, or by writing to us and we'll tell you how.

The daily leaderboard (iPhone, Game Center)

On iPhone, Latchline has a daily leaderboard run by Game Center, Apple's games service. It works only if you're signed in to Game Center on your iPhone (Settings > Game Center). Signing in is optional: the game plays the same without it, and you can sign in or out in Settings at any time.

What the game sends, and to whom: when you're signed in, the game sends the score of your best run of the day (a run played in one go) to Apple, with the date of that day's course. Apple ranks it on that day's leaderboard and shows it to other players with your Game Center nickname and avatar, according to your Game Center settings. The game also asks Apple for your rank, to show it next to the trophy. Nothing about the leaderboard goes to our own servers: the game sends it only to Apple.

Apple's role: Apple provides Game Center and its sign-in, and processes your Game Center profile and scores under its own terms and privacy policy: apple.com/legal/privacy. We never see your Apple Account.

What stays separate: your Game Center nickname and player ID never go to TelemetryDeck. The anonymous play statistics only say whether you're signed in and, after a score is posted, a rough band for your rank.

Why, and on what basis: to provide the leaderboard you chose to use by signing in to Game Center (Article 6(1)(b) GDPR).

Deleting your scores: Reset progress in the game doesn't remove scores that are already on the leaderboard. Apple holds your Game Center data; you can ask Apple for a copy or for its deletion at privacy.apple.com, or write to us and we'll tell you how.

Children

Latchline is made for a general audience of players aged 13 and over. Its content is suitable for all ages, but the game isn't directed at children. We don't knowingly collect personal data from children. The game asks no one for their age, name or contact details. If you believe a child has given us personal data, write to us and we'll delete it.

Your rights

Under the GDPR you have the right to access your data, correct it, have it deleted, restrict or object to its processing, and to data portability.

Because the game has no accounts and we only hold a hashed, random ID, we usually can't tell which statistics are yours. Before we can act on a request, you would need to give us information that identifies your install, and the game never shows that information to you. In practice, the simplest way to stop all statistics is to turn Anonymous stats off, or to uninstall the game. Either way the install ID is deleted, and nothing links a new ID to the old one. We will still answer every request within one month: ian.deherdt@it-erate.be.

You can complain to the Belgian Data Protection Authority (Gegevensbeschermingsautoriteit / Autorité de protection des données), Drukpersstraat 35 / Rue de la Presse 35, 1000 Brussels, dataprotectionauthority.be, or to the authority where you live.

Changes

If we change what the game collects, for example when ads arrive, we'll update this page and the date at the top before that version is released.
