# Privacy Policy - Foothold
Effective date: 20 July 2026
App: Foothold (`net.jc2dev.foothold`)
Developer: jc2dev.net
## Summary
Foothold is a single-player and local-multiplayer strategy game. It has **no
user accounts, no login, and no servers operated by us.** Your game progress
stays on your device. The only data that leaves your device goes either to
Google (for advertising) or directly to another player's device during a local
multiplayer game.
## Data stored on your device
The game stores the following in its private app storage:
- Saved games and manual save backups
- Settings (audio volumes, game speed, mini-map size, and similar)
- Tutorial progress
- Daily Challenge results
- Advertising state (such as when an ad was last shown)
- A randomly generated multiplayer player ID (see below)
- Diagnostic files if a multiplayer game desynchronises, which record the game
state at that moment and your device model
We cannot read any of this. It is removed when you uninstall the app.
Android Backup. If you have Android's backup enabled, Android may copy this
app-private data to your own Google account so it can be restored on a new
device. That copy is controlled by Google and your device settings, not by us.
You can turn it off in your device's backup settings.
## Advertising
Foothold displays ads through Google AdMob. To do this, the Google Mobile
Ads SDK may collect and send to Google:
- Your device's advertising ID, a resettable identifier used for ads
- Ad interaction data (for example that an ad was shown or clicked)
- Technical device and network information, including your IP address, which
Google may use to infer approximate (non-precise) location
This data is collected by Google under
[Google's Privacy Policy](https://policies.google.com/privacy), not by us. We do
not receive it in a form that identifies you.
Your choices. You can reset or delete your advertising ID, and limit ad
personalisation, in your device settings (typically Settings ? Google ? Ads).
In the European Economic Area, the United Kingdom, and Switzerland, the app
shows a consent dialog (Google's User Messaging Platform) before serving
personalised ads, and you can decline.
## Local multiplayer
Multiplayer runs directly between devices over your local Wi-Fi network or
Bluetooth. There is no matchmaking server and no game data is sent to us.
When you host or join a game, the following is exchanged with the other
players' devices:
- A random player ID generated on first launch. It is not linked to you,
your Google account, or your device's hardware identifiers. It exists so a
returning player can reclaim their slot in a saved game. It is regenerated if
you clear the app's data or reinstall.
- A display name, which is your device's model (for example "Pixel 8"), not
your name
- Game state and player inputs needed to keep the match in sync
Two things worth knowing:
- Wi-Fi games are not encrypted. Gameplay traffic on your local network is
sent in plain text, so someone else on the same network could in principle
observe it. It contains only gameplay data ? no accounts or personal
information. Bluetooth games use Android's encrypted Bluetooth connection.
- Bluetooth device names are shown. When you look for nearby Bluetooth
players, the app displays the device names your device reports. Phones are
often named after their owner, so a name like "Alex's Phone" may appear on
screen. This is only shown on your device ? it is not stored or transmitted
by us.
## Permissions
- Internet / network state ? serving ads and local multiplayer
- Wi-Fi multicast ? finding nearby games on your local network
- Bluetooth (connect, scan, advertise) ? Bluetooth multiplayer
- Approximate/precise location, on Android 11 and older only ? Android
required location permission to scan for Bluetooth devices on those versions.
The app does not use your location, and this permission is not requested
on Android 12 or newer.
## Children
Foothold is not directed at children. If you are in a jurisdiction where a
parent must consent to data processing for a child, please do not use the app
without that consent. If the app's Play Store target audience is ever set to
include children, this policy and the ad configuration must be revisited to
comply with Google Play's Families policy and applicable law such as COPPA.
## Data deletion
Because there are no accounts and we hold no data about you, deleting your data
means uninstalling the app, which removes everything it stored. To also remove
the backup copy, turn off or clear this app's data in your device's Android
Backup settings. To reset the advertising ID, use your device's ad settings.
## Changes
If this policy changes materially, the updated version will be posted at this
URL with a new effective date.
