DeSync (“the game”) is an iOS puzzle game published by Denys Lebedenko, an individual developer (“we”, “us”). For questions about this policy or about your data, write to dlebedenko.play@gmail.com.
This policy explains what the game does with data. It covers the iOS app only. It does not cover the App Store itself, which is operated by Apple.
The following is stored locally (iOS UserDefaults) and is not
transmitted to us:
Progress and earned hints are also mirrored to Apple’s iCloud key-value storage so that they survive a reinstall or a move to a new device. That copy lives in your iCloud account. We have no access to it. You can remove it in iOS Settings → your name → iCloud.
The game shows full-screen ads between levels and optional rewarded ads in exchange for an extra hint. Ads are delivered by Google AdMob (Google Ireland Limited / Google LLC), acting as an independent controller of the data it collects.
AdMob may collect and process:
If you allow tracking and consent to personalised ads, this data may be used to select ads based on your interests. If you refuse, the game still shows ads, but non-personalised ones; a limited amount of data is still processed for frequency capping, fraud prevention and measurement, which is what makes ad delivery possible at all.
How Google uses this data is described in the Google Privacy Policy and in How Google uses information from sites or apps that use our services.
The game supports Apple’s SKAdNetwork, a privacy-preserving install attribution system. It reports to ad networks that an install happened, without any identifier that points at you.
In the EEA, the UK, Switzerland and regulated US states, the game shows a consent form on first launch, before the advertising SDK is started at all. Your answer is stored on your device by Google’s User Messaging Platform.
You can change that answer at any time: open the game, tap Settings → Privacy settings. Withdrawing consent is as easy as giving it, and it takes effect immediately.
On iOS the game asks the system tracking permission (“Allow DeSync to track your activity across other companies’ apps and websites?”). Refusing costs you nothing: the game works identically, and you keep getting ads, just non-personalised ones. You can change your answer in iOS Settings → Privacy & Security → Tracking.
A sixty-level campaign is only as good as its difficulty curve, and the one question the design cannot answer on its own is where players give up. We use Google Firebase Analytics to answer it. The events sent are:
| Event | What it carries |
|---|---|
| level started | level number |
| level completed | level number, stars, moves used, par, seconds spent |
| level restarted | level number, how many attempts in a row |
| level abandoned | level number, moves used, seconds spent |
| hint used | level number, hints remaining |
| rewarded ad finished | level number, whether it was watched to the end |
Firebase adds its own automatic parameters: a random app-instance identifier, device model, operating system version, app version, language and country. None of this identifies you by name, and the game has no accounts to link it to.
These events are sent only after you have consented. Because we pass the same
consent on to Google for advertising purposes as well, this data may also be
used for ad measurement and personalisation — which is why the game declares
app-measurement.com as a tracking domain, and why iOS blocks it
outright if you deny tracking.
When the game crashes, a report is sent to Google Firebase Crashlytics containing the crash stack, device model, operating system version, app version, a randomly generated installation identifier and the number of the level being played at the time.
Crash reports are collected regardless of your advertising choice, on the basis of our legitimate interest in keeping the game from crashing. They are not linked to your identity and are never used for advertising.
This version of the game has no in-app purchases. There is nothing to buy, no payment information is ever requested, and the game contains no payment screen of any kind.
If a purchase is added in a later version, the transaction will be handled entirely by Apple: we would never see your payment details, and the only thing reaching the game would be a yes/no entitlement. This page is updated before any such change reaches players — see section 16.
The game may ask you to rate it using Apple’s standard in-app review prompt. Anything you write there goes to Apple, not to us, and we cannot tell whether you left a review.
No name, email, phone number, postal address or date of birth. No precise location. No contacts, photos, calendar, health data, microphone or camera access. No reading of other apps or files. The game requests none of these permissions, and the code contains no way to use them.
DeSync is not directed at children and is not listed in the App Store Kids Category. We do not knowingly collect personal data from children under 13 (or under the age of digital consent in your country). If you believe a child has provided such data, write to us and we will have it deleted.
Google processes the data described above on servers in the United States and other countries, under the safeguards set out in its own privacy policy, including the European Commission’s standard contractual clauses.
If you are in the EEA or the UK, the GDPR gives you the right to access, rectify, erase, restrict and port your data, to object to processing, and to withdraw consent at any time. You also have the right to lodge a complaint with your national data protection authority.
The practical ways to exercise these rights:
We do not sell personal information for money. Sharing data for cross-context behavioural advertising happens only where you have consented or not opted out. To opt out, refuse the tracking prompt or change your answer in the game’s privacy settings — that is our recognised opt-out mechanism for the CCPA/CPRA and equivalent state laws.
If the game starts doing something materially different with data, this page is updated and the “last updated” date at the top changes with it. The current version is always the one linked from the game’s settings and from the App Store listing.
