Privacy Policy
Arrow Puzzle · Effective date: 7 November 2026
This policy explains how LOST HUMANS LAB ("we", "us") handles information in the
Arrow Puzzle mobile game (Android package com.losthumanslab.arrowpuzzle).
1. What the game stores
Arrow Puzzle has no accounts. Except for online races (section 3), your progress, stars, best times, coins, boosters, daily streak, purchases and settings are stored only on your device. We do not receive them.
We do not ask for or collect your name, email, phone number, contacts, photos, location, camera or microphone.
2. Advertising
The game shows ads through Google AdMob: optional reward videos and occasional full-screen ads between levels. Google may collect and process your device's advertising ID, IP address, device information and ad interactions to deliver and measure ads and to prevent fraud. Ads in the game are limited to family-safe content.
- How Google uses this data: policies.google.com/technologies/partner-sites
- You can reset or delete your advertising ID, or opt out of personalised ads, in your phone's Settings → Google → Ads (or Settings → Privacy → Ads).
- In the European Economic Area, the UK and Switzerland, the game asks for your consent with Google's consent form. You can change your choice anytime in Settings → Ad privacy choices inside the game.
3. Online races (1v1)
When you play an online race, the game signs you in anonymously with Google Firebase (no email or password) and stores, for the length of the match, your player name, avatar colour, trophy count and race progress (arrows cleared, hearts left, result) in Firebase Realtime Database, so your opponent can see them. Friend rooms also store a short room code. Firebase may process your IP address and a device identifier to provide the service: firebase.google.com/support/privacy. When no other player is available, you may be matched with a computer-controlled practice opponent.
If you play the Weekly Cup, your player name, avatar colour and weekly points are stored in the same database under an anonymous ID so they can appear on that week's leaderboard, which other players can see.
Cloud save: a copy of your game progress (levels, stars, coins, boosters, settings and your player name) is stored in the same database under a random 12-character backup code shown in Settings, so you can restore it on another phone. Anyone who has that code can restore the progress, so keep it private. Purchases are not stored there; they are restored by Google Play.
4. Game statistics
To learn which levels are too hard and how the game is used, the game sends anonymous usage events to Google Analytics for Firebase: for example level started or completed, stars, time taken, boosters used, ads watched, races played and rewards claimed, together with an app-instance identifier and basic device information. We do not send your name with these events. Google's policy: firebase.google.com/support/privacy.
5. Reminders
If you allow notifications, the game schedules at most three evening reminders on your phone after your last visit (for your daily puzzle, streak and rewards). They are created on the device; you can turn them off in the game's Settings or in your phone's settings.
6. Purchases
In-app purchases are processed by Google Play. We never see your card or payment details. Google tells the game which items you own so it can unlock them; that record stays on your device and with Google.
7. Sharing puzzle codes
When you share a puzzle code, the game opens your phone's share menu with a short text. Nothing is sent unless you choose an app to share it with.
8. Deleting your data
Uninstalling the game, or clearing its storage in your phone's app settings, deletes everything the game stored. Data held by Google for advertising and purchases follows Google's own policies.
9. Children
Arrow Puzzle is a general-audience puzzle game and is not directed at children under 13. We do not knowingly collect personal information from children.
10. Your rights
Depending on where you live (for example under India's Digital Personal Data Protection Act, 2023, or the EU/UK GDPR), you may have the right to access or delete personal data and to withdraw consent. Because the game keeps your data only on your device, you control it directly; for anything else, email us.
11. Changes
If this policy changes, we will update the effective date above.
