Effective date: 11 October 2026
This policy explains what happens to information when you play HIGHWAY VERSUS (“the game”), a mobile game published by Muhammad Hazki Hariowibowo, trading as MHz Games (“we”, “us”).
The short version
- The game has no accounts, no login and no servers of its own, and never asks who you are.
- Your best distance, your cars and your settings are saved only on your own device, and may be included in your device’s own cloud backup if you use one. We cannot see them either way.
- The game sends a small amount of anonymous usage data — that a run started, how it ended, which gear you reached, whether you took a rewarded ad — under a random ID that is not linked to you. In the European Economic Area, the United Kingdom and Switzerland it sends none unless you say yes.
- The game shows ads supplied by Google AdMob. Google receives information from your device in order to serve those ads.
- If you are in the European Economic Area, the United Kingdom or Switzerland, you are asked to make a choice about ads the first time you play, and you can change it at any time from Settings → MANAGE AD CONSENT.
- The game is not directed to children under 13.
1. Information the game collects
Nothing that identifies you. The game has no accounts and never asks for your name, email address, contacts, location or anything similar.
Usage data
To understand how the game is played, it sends a small number of anonymous usage events: the app was opened; a run started, ended or was restarted; you shifted up a gear or dropped one; a rewarded ad was offered, taken or shown; an interruption ad was shown; the garage was opened; a car was previewed, bought, selected or repainted; a purchase was attempted and whether it went through; the profile was reset; the one-time “swing out” tutorial pause was shown; Stacks were earned, and from what.
Those events describe the driving and nothing else — how far the run got, which gear it reached, how it ended, and the in-game Stacks it paid. Stacks are not money: they cannot be cashed out and exist only inside the game.
This data is received and stored for us by Unity Gaming Services (UGS) Analytics, part of Unity Technologies, under its own privacy policy: https://unity.com/legal/game-player-and-app-user-privacy-policy. Alongside each event the Unity SDK sends what it collects by default: the app version, the platform and operating system version, the device model, the country the request arrived from, and a random installation ID the SDK generates the first time the game runs. That ID is not derived from you or from your advertising identifier, and we cannot connect it to you. Uninstalling the game discards it.
The same events are also received and stored for us by PostHog, a product-analytics service, on servers in the United States, under its own privacy policy: https://posthog.com/privacy. With each event the game sends the app version and build number, the platform, the country part of your device’s language setting (for example “ID” for Indonesian set up for Indonesia — a setting you chose, not your location), when the game was first opened on this device, and a second random installation ID that the game generates and keeps in its private storage. Like any web service, PostHog sees the IP address the events arrive from; the game tells it not to work out a location from that address, and we do not use it to identify anyone.
If you are in the European Economic Area, the United Kingdom or Switzerland, none of this is sent unless you agree. The game asks Google’s User Messaging Platform whether a privacy choice applies where you are. If it does, the game asks you — once, after the ad-consent form — whether it may send usage data, with ALLOW and NO THANKS as equal choices. This applies to both services in the same way. Until you say yes, no usage data or error reports are sent, and anything recorded while the game was waiting for your answer is thrown away unsent. If the game cannot find out where you are, for example on a first launch without a connection, it does not ask and sends nothing unless you have already said yes. Your answer is remembered on your device and applies wherever you later play: a no stays a no. You can change it at any time from Settings → USAGE DATA.
We use this for one thing: knowing where players stop. A game whose whole subject is a difficulty ramp cannot be tuned from the desk it was made on, and these events are how the ramp gets fixed for everyone.
The game also reports uncaught errors — the type of error and where in the code it happened. These carry no information about you.
Data kept on your device
The game writes two small files to its private app storage so it can remember your progress between sessions:
| What | Why |
|---|---|
| Your best distance and how many runs you have made | So a record survives closing the game |
| Stacks, the cars you own and the one you are driving | So you keep what you bought |
| The sound setting | So the game opens the way you left it |
| Whether you own the ad-free upgrade | So you are not shown ads you paid to remove |
| Your answer to the usage-data question (a separate file) | So you are not asked again — kept apart from the rest so that RESET PROFILE does not erase a choice you made |
Both are in the app’s private storage area and are readable only by the game. We never receive it and have no way to access it — the game does not upload it anywhere.
It may, however, be included in your device’s own cloud backup. If Android automatic backup or iCloud Backup is switched on, your device may copy this app’s saved data into your personal cloud account, exactly as it does for other apps. That backup belongs to you and is handled by Google or Apple under their own policies, not by us. You can turn it off in your device’s settings.
Uninstalling the game deletes both files from your device. A copy may remain in your own backup until that backup is replaced or you delete it.
2. Information collected by advertising
HIGHWAY VERSUS shows advertisements supplied by Google AdMob. To do this, the Google Mobile Ads SDK is included in the game and communicates directly with Google’s servers.
Google may receive and process information including your device’s advertising identifier, IP address, device type and operating system, general location derived from your IP address, and how you interacted with an ad. We do not receive this information. We see only aggregate, anonymous reports — for example, how many ads were shown in total. The usage data described in section 1 is never shared with Google, and the random installation ID is never sent to it.
How Google uses this data is governed by Google’s own policies:
- Google Privacy Policy — https://policies.google.com/privacy
- How Google uses information from sites or apps that use its services — https://policies.google.com/technologies/partner-sites
Whether the ads you see are personalised depends on the choice you make in the consent prompt described in section 4, and on your device’s own settings.
There are two kinds of ad in the game, and they behave differently. The interruption ad appears occasionally after a crash. The rewarded ad is never shown unless you ask for it — it is the one that revives a run, or doubles what a run paid.
3. Purchases
The game sells packs of Stacks, its in-game currency, and a one-time upgrade that removes interruption ads. If you buy either, the purchase is handled entirely by Google Play (or Apple’s App Store on iOS). Your payment details go to them, never to us — we never see or store your card number, billing address, or any other payment information. We receive only a confirmation that a purchase completed, which the game uses to grant what you bought.
Google’s and Apple’s handling of that transaction is covered by their own privacy policies.
4. Your choices
If you are in the EEA, the UK or Switzerland, the game shows a consent form the first time you play, provided by Google’s User Messaging Platform. Your answer determines whether the ads you see are personalised.
You can change your answer at any time from Settings → MANAGE AD CONSENT inside the game. That row appears wherever a consent choice applies to you.
On any device, you can also limit ad tracking through your device’s own settings:
- Android — Settings → Privacy → Ads, where you can reset or delete your advertising ID
- iOS — Settings → Privacy & Security → Tracking, and Settings → Privacy & Security → Apple Advertising
To remove ads, buy the ad-free upgrade from the in-game store (the Stacks plate). It removes the interruption ad after a crash. The rewarded ad stays available, because it is a way to get something — a second chance, or double the payout — rather than an interruption, and removing it would take something away from you rather than give something back.
To wipe what the game has saved about you without uninstalling, use Settings → RESET PROFILE. It clears the progress file described in section 1. Your answer to the usage-data question is kept.
To stop usage data being sent in the EEA, the UK or Switzerland, turn off Settings → USAGE DATA. It is off unless you said yes, and turning it off stops collection straight away. Elsewhere there is no switch for it inside the game — uninstall the game to stop it; the data is anonymous and is not connected to you.
5. Children
HIGHWAY VERSUS is not directed to children under 13, and we do not knowingly collect personal information from children under 13. Our declared target audience with both app stores reflects this.
If you believe a child has provided personal information through the game, please contact us at the address below and we will act on it.
6. Data retention
Usage data (section 1) is retained by Unity Gaming Services according to its own retention schedule for the plan we use. The copy held by PostHog is kept for at least twelve months — the minimum PostHog holds it for on the plan we use — and has no fixed expiry date: we remove it when we no longer need it, and all of it goes when we close the PostHog project. We keep usage data for as long as it is useful for tuning the game. It is held only as events under a random ID, and we never build profiles of individual players from it. Data stored on your device stays there until you reset the profile, clear the app’s data, or uninstall. Data held by Google as an advertising partner is retained according to Google’s own policies, linked in section 2.
7. Your rights
Depending on where you live, you may have rights to access, correct, delete, or restrict the processing of your personal data, or to object to it.
The usage data we hold is not linked to you. It sits under random installation IDs that the game and the analytics SDK keep in the app’s own private storage and never displays, so there is nothing you could send us that would identify your events, and nothing we could use to find them. That is one fact seen from both sides: it is why the data cannot be traced back to you, and it is why we cannot pick your events out of it to delete them on request. Uninstalling the game discards the ID, and nothing further is ever recorded against that install.
To exercise a right, or to ask anything about this policy, write to the address below.
8. Changes to this policy
If this policy changes, the new version is published at this address and its effective date at the top is updated. Material changes will also be noted in the app’s store listing release notes.
9. Contact
Questions about this policy or about privacy in HIGHWAY VERSUS:
The publisher is Muhammad Hazki Hariowibowo, trading as MHz Games, Jakarta, Indonesia. That address is the one the published page’s footer carries, and the only one to put in the Play Console listing — a second address that appears in one place and is never read is how a data-deletion request goes unanswered.
