When does the daily challenge change?
A new set of five games is released every day at 00:00 UTC. Everyone in the world plays the same puzzle on the same day.
My score or ranking looks wrong.
Scores are recomputed on our server from the round-by-round event log, so a result may differ slightly from what you saw mid-game. Your percentile keeps refining as more players finish the day. If it still looks wrong, email us with the date and your nickname.
I lost my streak / my records after reinstalling.
Braindle needs no account, so your history lives on the device and in iCloud-independent local storage. Deleting the app removes it and it cannot be restored. Email us if a streak broke while the app was still installed.
Do I have to allow tracking?
No. The App Tracking Transparency prompt only affects ad personalization. Decline it and every game, ranking and feature works exactly the same.
How do I stop the daily reminder?
Turn it off in the app's Settings tab, or in iOS Settings → Notifications → Braindle.
How do I request deletion of my data?
Email us from the address below with your nickname and player ID (Settings tab). We delete the associated ranking records within 7 days.
