Chochomy

Privacy policy

Effective 8 November 2026

Chochomy does not collect your name or any information that identifies you, and the developer sells nothing about you. Its only account is an optional cloud save. It is free with ads from Google AdMob, offers optional purchases through Google Play and the App Store, and sends anonymous play stats so the levels can be tuned (you can switch those off in the game's settings).

This policy covers the Chochomy app for Android and iPhone, made by Hundred Engine, an independent developer.

What the game keeps on your device

To remember your progress, Chochomy saves a small file in its own private storage on your phone or tablet. It contains:

• which levels you have finished and their star ratings, and the level in progress
• coins earned in the game, the themes you have unlocked and the one you use
• game statistics used for trophies (for example tiles cleared and best combo) and your daily treat streak
• settings: sound, music, vibration strength, day or night mode, and whether play stats are shared

This file stays on your device unless you turn on the optional cloud save (below); nobody else can see it. It contains no name, email address, contacts, location, photos, advertising ID or device identifiers. On Android the game turns off app backup, so the file is not copied to cloud backups either. On iPhone it can be part of your own iCloud or computer backup of the phone, which only you can open. Uninstalling the game, or clearing its storage, deletes it.

Anonymous play stats

To learn which levels are too hard or too easy, Chochomy sends anonymous play stats to GameAnalytics, a service that collects game statistics for the developer. The game shows a notice about this the first time it opens.

• What is sent: the level you start, win or lose, how long it took, stars and how many helps you used; coins earned and spent and what for; boosters used; tutorial steps reached; and when a play session starts and ends.
• With it, GameAnalytics records your phone model, its operating system version, the game version, your country (worked out from the connection), a random ID it creates for this install, and an ID that only apps from the same developer share (the App Set ID on Android, the identifier for vendor on iPhone). On iPhone it also records the advertising ID, but only if you allowed it in Apple's tracking prompt (see Ads).
• What is not sent to GameAnalytics: your name, email, contacts, precise location or photos, and on Android the advertising ID.
• The developer sees these stats only as totals and trends in the GameAnalytics dashboard, to tune the levels and the coin rewards. They are not sold, not used for ads, and not shared with anyone else.
• Turning it off: open Settings in the game and switch off Play Stats. Nothing more is sent from then on.

Ads

Chochomy is free and shows ads from Google AdMob. A full-screen ad may appear between levels, when you leave a result screen; never during a level. Short videos you choose to watch can give you a spare slot or double your coins.

• To show and measure ads and to prevent fraud, Google's ads software collects and shares with Google: your device's advertising ID, your IP address (used to estimate your general location), how you interact with the ads, and diagnostic information. Google's use of this data is described in its privacy policy.
• Where the law asks for it, Google's consent form appears first and you choose whether ads are personalised. Chochomy is not offered in the European Economic Area, the UK or Switzerland.
• On iPhone, Apple's prompt asks whether Chochomy may use your advertising ID. If you say no, the ID is not read, and the game stays exactly the same, with ads that are just less personal. You can change your answer any time in Settings, Privacy & Security, Tracking.
• On Android you can reset or delete your advertising ID, or turn off personalised ads, in your phone's settings (Settings, Google, Ads, or Privacy, Ads).
• The game asks Google not to show ads meant for mature audiences (Google's "PG" content rating at most).

Purchases

You can buy Chochomy Premium (no ads between levels, forever) and packs of coins. Every purchase is optional and is handled by Google Play on Android or the App Store on iPhone: the developer never sees your payment details. The game keeps a record on your device of what was bought so coins are added once and Premium stays on, and it sends the product and price to GameAnalytics as part of the play stats. If you use the cloud save, our server keeps a record of your purchases too (see Cloud save).

Premium comes back on a new phone: on Android with the same Google Play account, on iPhone with the same Apple ID (tap "Restore purchases" in the coin shop). With the optional cloud save, Premium also comes along to any phone where you sign in, Android or iPhone.

Cloud save (optional)

You can sign in from Settings, Cloud save, to keep your progress safe. Signing in and backing up are free. The game works fully without it.

• Signing in: with Google, or on iPhone also with Apple, on your phone's own sign-in screen. Google or Apple then hands the game a sign-in token, which it sends to our server. That token can include your name and email address: the server reads only the account's ID from it and throws the rest away without storing it. It keeps a scrambled (salted and hashed) form of that ID, so the account cannot be traced back to you from our data, never your name or email. With Apple, the server also uses a one-time code once, to end the sign-in's access at Apple right away, so it keeps no Apple token.
• What is stored on our server (Cloudflare, in the developer's account): a copy of the save file described above, with a few numbers about it (such as how far you are) so another phone can show that progress is saved; your coins, as a list of what was earned, spent and bought, so the balance is the same on every phone where you sign in; and a record of your purchases (the store's reference for the purchase, the product, and whether it was a test purchase) so Premium and bought coins are given on every phone, and only once. To check a purchase, the server asks Google Play or the App Store whether it is real and still valid.
• On another phone: sign in with the same account and your coins and Premium are there. Bringing your saved progress onto another phone comes with Premium; the backup itself is free.
• Deleting it: in the game, Settings, Cloud save, Delete my cloud save; or at sync.hundredengine.id/delete by signing in with the same account. This deletes Chochomy's cloud save, coins and purchase records at once; other games and apps by Hundred Engine that you signed in to keep theirs, and the account itself goes once none of them has anything left. Progress on your phones stays on them. Premium is tied to your Google Play or App Store account, so it comes back with Restore (tap "Restore purchases" in the coin shop). To stop the same purchase from being counted twice, the server keeps a scrambled (hashed) form of the store references of purchases already used, with nothing that points to you. Deleted data can stay in our database provider's recovery copies for up to 30 days.

What the game does not do

• It contains no crash-reporting or social SDKs. The outside services are GameAnalytics, Google AdMob, Google Play and the App Store, described above.
• Sign-in is only for the optional cloud save. There is no chat and no way to share content with other players.
• The developer does not sell data about you to anyone.

Permissions

On Android Chochomy asks for vibration, used for haptic feedback while you play (you can lower or turn it off in the game's settings); internet and network state, used for the play stats, ads and cloud save and to check for fixes and new versions; the advertising ID permission, used by Google's ads software; and Google Play's billing permission, used for purchases. Google's ads software also declares a few technical permissions it needs to work (such as keeping the device awake while a video plays). On iPhone the only thing Chochomy asks is Apple's tracking permission, described under Ads; saying no changes nothing in the game.

App stores

You download Chochomy through Google Play or Apple's App Store (or TestFlight while it is in testing). Those stores handle the download under their own privacy policies. While you play, the game also asks this website whether a small fix or a newer version is available. That check sends nothing about you or your progress; like any visit to a website it reaches our host (Cloudflare) with your device's network address, which we do not store or use. If you have agreed to share usage and diagnostics data with Google or Apple, they may give the developer anonymous, aggregated statistics such as install counts and crash reports.

Children

Chochomy is made for a general audience aged 13 and over and is not directed at children. The play stats contain no personal information, from children or anyone else.

Changes to this policy

If this policy changes, the new version will be posted on this page with a new effective date. A change that would collect more than is described here would only come with a clear notice in the game first.
