Box Shift

Privacy policy

Last updated: 8 November 2026.

In short

Box Shift is a game. It has no ads, no analytics and no tracking. It never sells your data and shares it with no one. It sends to the eliassaci.com site only what is needed to play online, for the ranking, and for the share of players who reached each station.

What stays on your phone

The game keeps a save file on your phone: your settings (sound, vibrations, animations, language), the game in progress, the adventure in progress, your statistics, your coins and chests, the skins you unlocked and wear, your team's first names, and the name you chose. This file never leaves the phone. It goes away when you uninstall the game.

The guest id

Without an account, you play as a guest. The game draws two random ids, unrelated to who you are or to your phone:

  • an installation id, sent with your progress (see below);
  • a guest token the online game server gives you, to find you again if the connection drops during a game.

They hold neither your name, nor your email address, nor your phone's advertising identifier.

Playing online

When you play online, the game connects to the Box Shift server (eliassaci.com). The server receives your guest token, your moves and the quick messages you pick from a fixed list (there is no free chat). It gives you a guest name (« Operator 4821 »). Games in progress stay in the server's memory and are gone when the game ends or the server restarts. The game server's logs only hold player counts, never an IP address or a token.

Progress and ranking

  • The share of players who reached each station (hardcore mode): the game sends the furthest station you reached on a line, with your installation id. The site keeps one row per player, line and mode, and only shows percentages from them.
  • The online ranking: only Google accounts are ranked on the site. As a guest, your ranking stays on your phone.

Google sign-in (Android only)

On Android, you can sign in with Google to keep your profile on several phones and play ranked games. On iPhone, this version has no Google sign-in: you play as a guest.

If you sign in, the eliassaci.com site receives from Google your Google account id, your email address, your first name and the address of your profile picture. It keeps:

  • your account: the Google id, the email address, the display name (your first name, or the name you chose in the game), the picture, your adventure progress, your ranking points, your wins and your losses;
  • a session: only a fingerprint of the token, not the token itself;
  • ranked games: the two accounts, the winner and why the game ended;
  • your progress per station, filed under your account.

Your email address is never shown in the game. The ranking shows your display name and your points. To delete your account and its data, write to us (see Contact). Signing out in the profile removes the session from the phone.

The web server

The eliassaci.com web server keeps the IP address and the time of each request in its access logs. These logs are rotated every day, kept for 14 days, then deleted.

Ads and purchases

This version has no advertising tool and no purchase. If ads or a subscription come, this text will be updated first.

Children

The game is meant for players aged 12 and over. It has no free chat and asks for no personal data to play as a guest.
