Nothing leaves your device unless you tap Upload or Add me. When you do, we send only: your nickname, your avatar choice, your score, your time (Maxxing only) and a scrambled (hashed) device code that stops double entries.
We never send your answers, your name, email, contacts, location or any ad tracking. No accounts, no ads.
Mini Maxxers uploads nothing at all.
To remove your entries, open About → Remove my scores in the app, or email contactwa@libertarians.org.au.
On the web version, the device code is kept in this browser's storage; clearing site data gives you a new one.
