Nonogami privacy policy

Nonogami is a picture logic puzzle game published by Jogiba Gaming for Android (Google Play) and iPhone (the App Store). This policy explains what the game stores, what leaves your phone, and who else can see it. Where the two apps differ, the difference is spelled out.

No account, nothing in the cloud

Nonogami has no sign-in, no account and no cloud save. Your progress (solved pictures, daily results, streak) and your settings are saved only in the game’s storage on your phone. Settings, Erase all progress deletes them, and so does uninstalling the game, unless your phone’s own backup (Android backup or an iPhone backup) restores them. Because there is no account, we hold nothing about you on a server.

Analytics

The game uses Google Analytics for Firebase to understand how it is played: a few game events such as a puzzle started or solved, hints used, the tutorial, and the steps of a purchase. Firebase adds the device model, operating system, app version, approximate country and a random identifier for this installation of the game. There is no user id. Analytics is set up not to use the advertising ID or ad storage, on Android or on iPhone, and nothing is sent from development builds.

Crash reports

When the game crashes, Firebase Crashlytics sends a crash report: what went wrong in the code, the device model, operating system and app version, and a random installation identifier. We use it only to fix bugs. Nothing is sent from development builds.

Free players see ads from Google AdMob, never during a puzzle:

an occasional full-screen ad after a solved puzzle: none in your first three days of play, then at most one every two solved puzzles and three minutes apart;
a short video when you tap Hint, if you choose it. The button shows a video icon and an AD badge when it will play one, and the hint is given when the video ends. When no ad can play, hints are free.

There are no banners and no ads when the app opens. The Remove Ads purchase removes every ad and makes hints free.

To show and measure ads and to prevent fraud, AdMob processes:

the device’s advertising ID, on Android;
on iPhone, the advertising identifier (IDFA), only if you allow tracking when Apple’s App Tracking Transparency prompt asks. Otherwise it is never read;
your IP address, and the approximate location worked out from it;
device and app information: the model, operating system and app version;
your interactions with ads, such as views and taps.

Where the law asks for it (for example in the European Economic Area, the UK and Switzerland), Google’s consent message asks for your choice before any ad is requested, and Settings, Privacy choices changes it later. On Android you can reset or delete the advertising ID in your device settings; on iPhone you can change your tracking answer at any time in Settings, Privacy & Security, Tracking.

Ads are limited by Google’s content ratings: to G (general audiences) on iPhone and to PG (parental guidance) on Android. How Google uses this data is explained in Google’s privacy policy and on how Google uses information from apps that use its services.

Settings the game downloads

The game downloads two small files from our Firebase Hosting site: a settings file that switches ads on or off, and a version file that tells the game when an update is available. Nothing about you is sent with these requests beyond what any web request carries, such as your IP address.

Daily reminders

Reminders are off until you turn them on, and your phone asks for your permission first. You get at most two a day, and only while that day’s picture is unsolved. They are written and scheduled on your phone: no reminder, schedule or device token is sent to us or to anyone else. Turn them off at any time in Settings or in your phone’s notification settings. On Android the game may start briefly when your phone restarts, only to put planned reminders back.

The share button opens your phone’s share sheet with a short text that never shows the picture. You choose where it goes; the game sends nothing itself.

Purchases

Remove Ads is a one-time purchase, not a subscription, sold by Google Play on Android and the App Store on iPhone. It removes every ad and makes hints free. The store handles payment; we only learn that the purchase was made, never your payment details. Google Analytics for Firebase records that a purchase was made (the product, price and currency). Restore it in Settings.

Who else sees your data

Google, in two roles: as Firebase, which runs analytics, crash reports and the settings files for us as a service provider, and as AdMob, the ad network that shows the ads. We do not sell your data.

How long we keep it

Analytics and crash data are kept by Google for a limited time under Firebase’s retention settings and then deleted. Data AdMob processes for ads is kept under Google’s own policies. Everything else stays on your phone until you erase it or uninstall the game.

Deleting your data

There is no account to delete. Settings, Erase all progress deletes everything the game keeps on your phone. See Delete your data.

Children

Nonogami is a game for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes

If this policy changes, the date at the top of this page changes with it, and important changes are announced in the game.
