Privacy Policy

The short version

The game runs entirely on your device. The ads do not. Kakuro Grid is free and funded by advertising, which is served by Google AdMob. Showing an ad means Google receives data about your device. Everything else — your puzzles, your times, your progress — stays on your iPhone. There is no account, and we run no servers of our own.

What stays on your device

Your best times and solve statistics, XP, Journey progress and stars, your Daily streak and calendar, your lesson and training progress, an unfinished puzzle you can resume, and your settings (board look, sound, haptics, hints and checks, text size) are stored locally. The app also keeps a log of finished puzzles — mode, duration, board size, hints used and the puzzle seed — on the device, which we use for nothing but the game itself. None of it is transmitted anywhere and we cannot see it. Deleting the app deletes all of it. Every puzzle is generated on the device and the game is fully playable with no connection at all.

Advertising

Ads are provided by Google AdMob. Kakuro Grid shows a full-screen ad after some finished puzzles — never during one — and optional ads you can choose to watch in exchange for an extra hint or an extra check of your entries. To serve and measure those ads, the Google Mobile Ads SDK collects:

• Your IP address, which Google may use to estimate a coarse location
• Device and advertising identifiers — including Apple's advertising identifier (IDFA) if you allow tracking
• Advertising data — which ads were shown, and whether you interacted
• App interaction data, such as ad requests and views
• Crash logs, performance and other diagnostic data

Google uses this to select and measure ads, and for analytics. We receive only aggregate earnings reports — never data about an individual person. How Google handles it is described in the Google Privacy Policy and in how Google uses information from apps that use its services.

Your choices

If you are in the EEA, the UK or Switzerland, Kakuro Grid asks for your consent before requesting any ad, using Google's consent dialog. Personalised ads are shown only if you agree — the legal basis is your consent under Art. 6(1)(a) GDPR. You can change or withdraw it at any time in the app: Settings → Privacy options. Withdrawing does not affect processing that already happened.

Separately, iOS asks whether Kakuro Grid may track you across apps. If you decline, no advertising identifier is used and you will see non-personalised ads instead — the game itself is identical either way. You can change this under Settings → Privacy & Security → Tracking.

Removing the ads

Kakuro Grid offers a one-time purchase that removes all ads for good. After it, the Google Mobile Ads SDK is not started at all: no consent dialog, no tracking prompt, no ad requests, and the extra hints and checks no longer need an ad. The purchase is handled entirely by Apple's StoreKit: Apple takes the payment and tells the app, on the device, that you own it. We never receive your name, payment card, or billing details, and we hold no purchase record of our own — restoring the purchase on a new device asks Apple, not us.

Game Center

Kakuro Grid supports Apple Game Center for leaderboards and achievements. If you are signed in to Game Center, your best Classic times, your Journey level, your Daily streak and your unlocked achievements are sent to Apple and shown under your Game Center identity — which may be visible to other players on public leaderboards. This is processing by Apple under the Apple Privacy Policy; we never see who you are, only that a score exists. If you are not signed in, nothing is submitted and the game plays exactly the same. You can sign out or turn Game Center off under Settings → Game Center.

Children

Kakuro Grid is rated 4+ because it contains nothing objectionable, but it is a general-audience puzzle game and is not directed at children. It is not part of the App Store Kids Category. We do not knowingly collect personal data from children under 13. If you believe a child has provided data through the ads in this app, contact us and we will help you raise it with Google.

Your rights

Under the GDPR you have the right to access, correct, delete, or restrict the processing of your personal data, and to object to it or request portability. Because we hold no data about you ourselves, requests concerning advertising data need to go to Google as the controller for that processing — start with the Google Privacy Policy. Requests concerning Game Center go to Apple. Write to us at the address below and we will point you the right way. You also have the right to complain to a supervisory authority.
