By downloading the Application from the Apple App Store or Google Play Store, and any update thereto (as permitted by this License Agreement), You indicate that You agree to be bound by all of the terms and conditions of this License Agreement, and that You accept this License Agreement.

The parties of this License Agreement acknowledge that Apple is not a Party to this License Agreement and is not bound by any provisions or obligations with regard to the Application, such as warranty, liability, maintenance and support thereof. Appreasy LLC, not Apple, is solely responsible for the licensed Application and the content thereof.

1. THE APPLICATION Suko (hereinafter: Application) is a piece of software created to play and solve Suko puzzles.

The Application includes an optional auto‑renewing subscription currently named "Suko Grandmaster" that removes advertising and unlocks certain premium features (including, without limitation, unrestricted solver access, unlimited hints, and other advanced tools). The free (non‑subscription) tier is ad‑supported, and certain features (such as starting a new game, using hints, or accessing the solver) may be restricted or gated unless and until an ad has been successfully displayed.

The Application is not tailored to comply with industry-specific regulations (Health Insurance Portability and Accountability Act (HIPAA), Federal Information Security Management Act (FISMA), etc.), so if your interactions would be subjected to such laws, you may not use this Application. You may not use the Application in a way that would violate the Gramm-Leach-Bliley Act (GLBA).

Use of any automated tools or methods to bypass gameplay mechanics, ads, or purchase gates other than features expressly provided within the Application (e.g., subscriber‑only solver tools) is prohibited.

If an ad cannot be delivered (including due to lack of network connectivity or use of system settings intended to block ads), the Application may delay or block access to ad‑supported features until an ad can be shown or you subscribe to remove ads. The Application may automatically retry ad loading when connectivity is restored. 8.3 Frequency and Messaging. The Application may show reasonable prompts or messages encouraging subscription to remove ads and unlock premium features. Such prompts will be dismissible and shown at a reasonable frequency.

9. CONNECTIVITY AND OFFLINE USE 9.1 A network connection is required for certain functionality, including but not limited to: purchase and subscription management; paywall and product availability; restoring purchases; and delivery of ads for the free tier. 9.2 Subscribers. Active subscribers may access premium features without ads and, where designed, may access gameplay offline. Some subscription management functions still require an internet connection. 9.3 Non‑Subscribers. Non‑subscribers acknowledge that certain gates, levels, or actions in the Application may be unavailable while offline until an ad can be successfully displayed.

THIRD‑PARTY SERVICES 10.1 The Application integrates third‑party services such as Apple App Store / Google Play billing, RevenueCat (in‑app purchase management), and advertising networks (e.g., Google). Your use of these services is subject to the applicable third‑party terms and privacy policies in addition to this Agreement. The Licensor is not responsible for third‑party services and provides them on an "AS IS" and "AS AVAILABLE" basis. 10.2 To the extent the Application displays content or pricing sourced from third parties, such information is provided for convenience only and the platform provider’s information will control in the event of any discrepancy.
