Terms of use

The app. Sudoception is published by NetSmiths Ltd and distributed through Apple's App Store under Apple's standard licence terms. It's for personal, non-commercial use.

Purchases. The daily puzzle is free. Pro is a single one-off purchase of £4.99 (or the local equivalent) handled entirely by Apple, with Family Sharing enabled. Nothing renews. A future major version may be a separate upgrade — if it is, we'll say so plainly before you buy anything.

Refunds. Purchases are made through Apple, so refunds follow Apple's App Store process.

Fair play. Leaderboards run on Game Center. Only on-day solves count on the daily board, and buying Pro never buys a place on it. We may remove entries that are plainly not human solve times.

The puzzles and their gradings are © NetSmiths Ltd. Share cards are yours to share anywhere.
