These terms apply to your use of Pure Nonogram, a local-first offline nonogram puzzle app.

Using The App

Pure Nonogram is provided for personal entertainment. You may use the app to play the included puzzles on your own devices.

Purchases

Full Unlock is a one-time non-consumable in-app purchase processed by Apple App Store or Google Play. Store purchase rules, refunds, taxes, and account handling are managed by the store where you made the purchase.

No Subscription

Pure Nonogram does not use a subscription for Full Unlock. Restoring a previous purchase requires the same store account used for the original purchase.

Puzzle Content

Puzzle content, app design, code, and related materials are owned by Pure Nonogram or its developer. Do not redistribute or resell the app content outside normal app use.

Service Changes

The app may receive updates to improve reliability, compatibility, puzzle content, or store purchase support. We may change or discontinue support for older app versions when platform requirements change.
