Data We Collect

Sketchaphone is designed to collect as little data as possible. We do not require accounts, emails, or passwords.

Stored persistently

Temporary (session only, never persisted)

  • User-submitted drawings and text — stored temporarily on the server during gameplay only. These are not shared externally and are deleted when the server restarts.
  • Session cookies — used to track your active game session. Expire after 2 hours of inactivity.
  • Player tracking cookies — used to reconnect you to a game if you refresh or rejoin. Expire after 24 hours.
  • Go session cookies — used to identify you in a Go game. Expire after 24 hours.
