Arrow Chain Puzzle
Arrow Chain Puzzle Privacy Policy
Last updated: September 20, 2026
Overview
Arrow Chain Puzzle (Japanese name やじるし パズル; "the App") is a personal puzzle app in which you tap arrows to send them off the board.
All settings, records, and boards in progress are stored only on your device. They are never sent to the developer's or any third party's servers. The developer never receives any of your data.
The App displays ads. Ads are served by Google (AdMob), and for this feature alone the device communicates with Google. See "Advertising" below.
Information stored on your device
| Type | Contents | Location |
|---|---|---|
| Records | Levels cleared, and per-level stars, best score and fewest moves, plus the stars you hold | App-private storage on device |
| Board in progress | The level you left and the moves made so far | App-private storage on device |
| Settings | Sound, haptics, board colour, and language | App-private storage on device |
All of the above is stored in the private area iOS allocates to the App (the app sandbox). Other apps cannot read it.
Information we do not collect
The App does not collect any of the following:
- Personal information such as name, email address, or phone number
- Location data (the App never asks for location permission)
- Contacts, photos, calendar, or data from other apps
- Usage analytics (the App contains no analytics SDK or crash reporting SDK)
The App has no account registration and requires no sign-in.
Your records and boards are never used for advertising. No game data is passed to ad serving; it never leaves the device.
Advertising
The App shows two kinds of ads. Both are served by Google (AdMob).
- Banner ads appear at the bottom of the title screen and the level list. They are never shown on the board screen.
- Rewarded (video) ads appear only when you are short of stars and choose "Watch an ad". Watching one to the end adds 3 stars. They never appear unless you choose them, and there are no full-screen ads that interrupt play or the end of a level.
- No tracking. The App does not request App Tracking Transparency permission and does not obtain the advertising identifier (IDFA).
- However, Google does use device identifiers for frequency capping and fraud prevention. Identifier use within that scope is unavoidable.
Data that Google obtains in the course of serving ads is governed by Google's privacy policy:
https://policies.google.com/privacy
https://policies.google.com/technologies/partner-sites
You can limit personalized advertising in iOS under Settings → Privacy & Security → Apple Advertising and Tracking.
Data handled by the advertising SDK
The App Store "App Privacy" section lists the following data that Google's SDK handles in the course of serving ads. All of it is used for ad delivery and fraud prevention only; it is not linked to your identity and is not used for tracking.
- Identifiers (device ID) — a device identifier may be used for frequency capping and fraud prevention.
- Usage data (advertising data, product interaction) — which ads were shown or tapped.
- Diagnostics (crash and performance data) — diagnostic information that keeps the ad SDK running reliably.
- Coarse location — the IP address that reaches Google as part of any network request may be used to estimate a country- or region-level location.
The App itself never collects or stores any of this.
Transmission outside the device
Apart from ad serving, the App performs no network communication. It contains no analytics SDK or crash reporting SDK.
Data retention and deletion
- Records and settings remain on the device until you delete them.
- Uninstalling the App removes all data it has stored from the device.
Because the developer holds none of your data, there is nothing to request deletion of from the developer.
Children
The App is not directed at children under 13, and it does not knowingly collect personal information from children under 13.
Changes to this policy
If this policy changes, this page will be updated and the "last updated" date revised.
