Delta Mile

Privacy Policy

This policy covers the Android game Delta Mile (package se.arxify.deltarun). It is written in English because the game and its store listing are in English.

Who is responsible

The data controller for the processing described here is:

• Arxify AB, company registration number 559399-8122
• Solnavägen 29G, 171 45 Solna, Sweden
• info@arxify.se

The short version

Delta Mile has no accounts, no sign-in and no analytics. You never type a name: the game deals you one, like a race number.

Two things can leave your device, and both are your choice. Google needs some data in order to show ads, and in the EU that only happens after you have said yes. And if you join the leaderboard, your dealt racer name and your scores are sent to our server in the EU. Say no to the leaderboard and nothing at all is sent — not even an identifier.

What stays on your device

The game saves a small amount of data in local storage on your phone. It is never transmitted anywhere and is deleted when you uninstall the app.

• Settings — control mode, camera mode, and your music and engine volume levels.
• Progress — your best times, ghost-race runs and scores.
• Your racer name and a random id — dealt when you first play, so that a leaderboard entry stays yours. They stay on the device unless you join the leaderboard, and they are not tied to your advertising ID, your Google account or anything else about you.
• Your leaderboard answer — whether you joined, so you are only asked once.

The leaderboard

The leaderboard is optional. The first time you start a run, the game shows you the racer name it dealt you and asks whether you want to post to the global board. If you decline, the game never contacts our server at all — no identifier, no score, no request. You can play the whole game that way.

If you join, this is everything that is sent and stored:

• Your racer name — for example Rapid Marlin 47. It is generated by the game from a fixed word list, and our server refuses any name it could not have dealt itself, so the board cannot carry a real name.
• The random id described above, so your own entry can be updated and so you can erase it later.
• Your best score and how far the run got, and your best time on each racing canal.
• A salted one-way hash of your IP address, kept for at most one hour and used only to stop one person flooding the board. The address itself is never stored, and the hash cannot be turned back into it.

Nothing else is sent: no email address, no account, no device identifiers, no advertising ID, no location. The data is held in the EU — a Neon database in Frankfurt, reached by functions that also run in Frankfurt — and is never sold, shared or used for advertising. We keep it for as long as the leaderboard exists, because an old score is the whole point of a leaderboard, or until you erase it.

To leave and erase everything: Menu → Leaderboard → Leave and erase my scores. Your name, your scores and your times are deleted from the server immediately, and the game stops sending. There is no form to fill in and no email to wait for. Our legal basis for this processing is your consent, which you withdraw by leaving.

Advertising

Delta Mile shows ads through Google AdMob. There are two placements: a full-screen ad between some stages, and an optional rewarded video you can choose to watch for an extra retry. There are no banner ads, and no ad is ever shown while you are driving.

To serve and measure those ads, Google may process your advertising ID, IP address, approximate location derived from it, device and app information, and how you interacted with the ad. Arxify never receives this data — we only see aggregate revenue figures. What Google does with it is described in How Google uses information from sites or apps that use our services and in the Google Privacy Policy.

Your consent, and how to change it

If you are in the EEA, the UK or Switzerland, the game asks for your consent the first time you open it, using Google’s own consent form. No ad is requested before you have answered. Declining personalised ads does not lock you out of any part of the game.

You can change your answer at any time: Menu → Ad privacy settings on the title screen, or the gear button while playing. The same choices reopen, and the new answer applies immediately.

You can also reset your advertising ID, or opt out of ad personalisation entirely, in Android under Settings → Google → Ads.

Permissions the app asks for

• Internet and network state — used only to fetch ads. The game itself is fully offline and plays without a connection.
• Advertising ID — used by the Google Mobile Ads SDK, as described above.
• Keep the screen on — so the display does not sleep mid-race.

Children

Delta Mile is not directed to children. It is not designed for, aimed at, or marketed to children under 13, and we do not knowingly collect any data from them.

Your rights

Under the GDPR you have the right to access, correct, erase and object to the processing of your personal data. If you have not joined the leaderboard, Arxify holds nothing about you at all. If you have, the fastest route is the in-game one above — Menu → Leaderboard → Leave and erase my scores — which erases it on the spot. Requests about ad data are best directed to Google. For anything else, or to ask us a question about this policy, write to info@arxify.se or to Arxify AB, Solnavägen 29G, 171 45 Solna, Sweden.

If you believe your data has been handled unlawfully you may lodge a complaint with the Swedish Authority for Privacy Protection (IMY), imy.se.

United States state privacy rights

If you live in California, Colorado, Connecticut, Virginia, Utah or another state with a comprehensive privacy law, the following applies to you in addition to everything above.

Through Google’s advertising SDK, these categories of personal information may be collected: identifiers (your advertising ID and IP address), coarse geolocation derived from that IP address, internet and application activity (which ads you saw and interacted with), and technical device information. Arxify receives none of it — only aggregate revenue reporting.

We do not sell personal information for money, and we never have. However, showing you personalised ads may count as a “sale” or as “sharing for cross-context behavioural advertising” under some state laws. You can turn that off:

• In the game — Menu → Ad privacy settings, on the title screen or behind the gear while playing.
• On your device — Android Settings → Google → Ads, where you can opt out of ad personalisation or delete your advertising ID entirely.

You also have the right to know what is collected, to correct it, to request deletion, and to appeal a decision we make about such a request. We will never give you a worse experience in the game for exercising any of these rights. Since Arxify holds no personal data about you, requests about advertising data are best made to Google; for anything else, write to info@arxify.se.

We do not knowingly collect or share the personal information of anyone under 16.

Changes to this policy

If the game changes in a way that affects this policy, this page is updated and the date below changes with it. Material changes are also noted in the app’s release notes on Google Play.
