Privacy Policy
Effective: 2026-10-31
Perfect Stack is an arcade stacking game published by Hevron Salad Marketing LTD (חברון שיווק סלטים בע"מ), company number 516398179. This policy covers Perfect Stack Android releases, including releases that use Google AdMob and Singular campaign measurement as described below.
Information used by the app
The game stores settings, tutorial status, scores, earned in-game currency, unlocked themes and cosmetics, assists, and other gameplay progress on your device. When internet access is available, it also creates a pseudonymous account and sends gameplay progress, scores, stack height, and whether a run used an assist to our cloud service. We do not ask for your name, email address, contacts, precise location, or advertising identifier to use this account.
Why we use it
We use cloud data to restore progress, synchronize supported devices, operate provisional leaderboards, provide support, and protect the integrity of ranked results. Assisted results are saved for continuity but are excluded from ranked leaderboards.
Cloud provider and retention
Cloud data is processed for us by Supabase in its Frankfurt, Germany region. Supabase may process technical connection information such as IP addresses and service logs to provide and secure the service. Game data is retained while the pseudonymous account exists, unless a longer period is legally required.
Local diagnostics
The game creates a local diagnostic gameplay log containing random installation, session, and run identifiers, app version, platform, gameplay events, scores, and performance details. This file stays on the device and is not transmitted to us or to a third party by this release.
Payments, advertising, and analytics
The game does not process real-money purchases. AdMob-enabled Android releases can load optional rewarded videos that grant a clearly described in-game bonus after the reward is earned. They can also show interstitial ad breaks between completed runs, after at least three runs and with at least two minutes between full-screen ads. Viewing or closing a rewarded ad restarts both the three-run count and the two-minute interval. Ads that are not ready at a run break are skipped; the game does not wait for an ad to load. There are no banner or app-open ads. The public 0.1.3 release has no production advertising. Release 0.1.7 uses production Google AdMob advertising units. Internal test version 0.1.6 uses Google test advertisements, which generate no revenue. You can play without choosing a rewarded bonus video.
The Google Mobile Ads SDK may automatically collect and share an IP address (which can be used to estimate approximate location), app interactions such as app launches, taps and video views, diagnostic and performance information, and device or account identifiers such as the Android advertising ID and app set ID. Google describes these uses as advertising, analytics, and fraud-prevention purposes. This information is encrypted in transit. Google’s handling of information is described in How Google uses information from sites or apps that use its services.
Perfect Stack uses Singular as a mobile measurement provider to understand whether an installation or app session resulted from one of our advertising campaigns and to measure aggregate campaign performance. Singular may process technical information such as the Android advertising identifier where available, app-set or app-scoped identifiers, IP address, user agent, app version, installation and session information, and campaign-attribution metadata. An IP address may indicate approximate location. We also send one limited gameplay-quality event named second_run_start when the second run begins. We do not attach the game's local installation ID, run ID, cloud account ID, name, email address, free-text content, score, stack height, or precise location to this event. Singular processes this information for attribution, campaign measurement, analytics, and fraud prevention. See Singular's Privacy Policy.
Where required, the app asks for advertising consent through Google’s User Messaging Platform before requesting an ad and provides a privacy-options entry point when Google requires it. The available ad and the way it is selected may depend on the choice made in that message. We do not sell personal information or use Perfect Stack cloud-save data to target advertising.
Device permissions
The game does not request contacts, camera, microphone, photo library, precise-location, or Android location permission. Google may infer approximate location from the device IP address as described above. Internet access is used for installation, updates, cloud save, account deletion, leaderboards, consent management, rewarded videos, and interstitial ad breaks.
Children
Perfect Stack is designed for a general audience and is not submitted to Apple’s Kids Category. We do not knowingly collect personal information from children through this release.
Data choices
You can permanently delete the pseudonymous cloud account, its server-saved progress, and its leaderboard entries from the in-game settings. Local progress, attribution state, and diagnostic logs remain until you clear the app’s storage or delete the app. You can reset or limit the Android advertising identifier through supported Android privacy settings. For help with a deletion, access, objection, or restriction request involving campaign measurement, contact us at the address below.
