Privacy Policy — Arrow Puzzle Hard
Last updated: 14 October 2026
Arrow Puzzle Hard (Android package com.quantumlogic.baan) is an
arrow escape puzzle game published by Quantum Logic. This policy explains what
the app does with data.
What we collect ourselves
No personal data. Arrow Puzzle Hard has no account, no sign-in and no server of ours. Your level, stars, hints, streaks, statistics and settings are stored on your device only, and are removed when you uninstall the app. The puzzles themselves are generated on your device and play offline.
Advertising
The game is free and shows ads from Google AdMob: you can choose to watch a rewarded video for extra hints or an extra heart, and a short ad can appear between levels (after you tap “Next level”). To show and measure ads, and to prevent fraud, Google may collect and process:
- your device's advertising ID and app set ID
- your approximate location, estimated from your IP address
- information about your device and how the app and the ads perform
- how you interact with ads
Google acts as an independent controller of that data. Its practices are described at policies.google.com/technologies/partner-sites and its privacy policy is at policies.google.com/privacy. Ads are limited to content suitable for all audiences.
Analytics
Arrow Puzzle Hard uses Google Analytics for Firebase to understand how the game is played, for example which levels are too hard and where players stop. The events describe the game, not you: which board was started, solved, lost or left, its size and number of arrows, the time it took, stars, mistakes, hints used, and whether a reward video was watched. Google also receives a random app-instance ID, the advertising ID, your device model and operating-system version, and an approximate location derived from a masked IP address.
You can turn this off: open Settings in the app and switch off “Share anonymous stats”. Collection then stops inside the SDK itself. Google processes analytics data for us as a service provider; see firebase.google.com/support/privacy.
What the app never collects
No name, no email address, no account, no precise location, no contacts, no photos, no files, no messages, no health data and no payment data. The app asks for no runtime permissions; it only uses network access for the ad and analytics services described above.
Children
Arrow Puzzle Hard is not directed at children under 13, and we do not knowingly collect personal data from them.
Security and retention
Data sent to Google is encrypted in transit (TLS). Analytics data is kept according to the retention settings of our Google Analytics property; ad data is kept by Google as described in its own policies.
Your rights
We hold no personal data ourselves, so there is nothing on our side to export. To ask for analytics data about your installation to be deleted, or for any privacy question, write to us at the address below. For data held by Google as an advertising partner, use the Google links above.
Changes
If this policy changes, the new version will be posted at this address with a new date.
