(SECUSO) Play the battleship game on your smartphone without ads or permissions.
About this app
With the Privacy Friendly Battleship app, you can play the popular game "Battleship" conveniently on your smartphone. The goal of the game is to sink all of your opponent's ships by taking turns "shooting" at the opponent's board.
The game offers two game modes: - Player vs. Computer - Player vs. Player
The player can choose between 5x5 and 10x10 board sizes and place their ships freely. The number of ships can be selected before the game. Ships of sizes 2 (submarines), 3 (destroyers), 4 (cruisers), and 5 (battleships) are possible.
What distinguishes Privacy Friendly Battleship from other similar apps?
1. No Permissions Privacy Friendly Battleship does not require any permissions. For comparison: The top ten similar apps available in the Google Play Store require an average of 6.1 permissions (as of November 2017). These include access to networks, the internet, and location data.
2. No intrusive ads Many other free apps in the Google Play Store display intrusive ads, which, among other things, can shorten battery life and consume data.
The app belongs to the group of Privacy Friendly Apps developed by the SECUSO research group at the Karlsruhe Institute of Technology. More information at: https://secuso.org/pfa

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.secuso.privacyfriendlybattleship is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.2.6 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Battleship Game (Privacy Friendly) first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Battleship Game (Privacy Friendly), and a listing is removed when the evidence for it stops holding up.
