Terms
The ground rules for using SUDORI, written to be read.
Last updated 15 November 2026
Who we are
SUDORI (the app and this website) is made by David Coelho, an independent developer based in Portugal. You can reach us at support@playsudori.com.
These terms
These terms apply when you use SUDORI, together with the licence of the store you got it from (Apple’s Licensed Application End User License Agreement or the Google Play Terms of Service).
Using SUDORI
You get a personal, non-transferable licence to use SUDORI. Please don’t try to break, overload, reverse engineer or misuse the app, its online services or this website.
Free play and optional purchases
All puzzles, modes, lessons and hints are free. SUDORI Plus and theme packs are optional one-time purchases of cosmetic items that give no gameplay advantage. They are sold, charged and refunded by Apple or Google under their own terms, including any right of withdrawal, and can be restored on your devices through the store. SUDORI Plus includes every theme pack.
Online features and behaviour
Together rooms, accounts and sync are optional and free. Don’t use names or messages that are offensive or unlawful, or that impersonate others. Abusive content may be removed and access to online features suspended. Rooms close after 24 hours, and online features may sometimes be unavailable.
Your content
The names you choose and the postcard messages you write remain yours. You allow SUDORI to use them only to deliver them to the people you share them with.
Our content
The SUDORI name, companions, artwork, sounds and software belong to their creator. The fonts are used under the SIL Open Font License, and other open-source licences are listed in the app.
Changes
SUDORI may change over time, and features may be added or retired. Purchased items stay yours while the app is available. If these terms change in an important way, the app or this page will tell you before the change applies. If you don’t agree, you can stop using SUDORI and delete your online account at any time.
Liability
SUDORI is built with care, but we can’t promise it will always be free of errors or interruptions. Your rights as a consumer, including the legal guarantee for digital content, are not affected. Except where the law doesn’t allow it to be limited, for example for intent or gross negligence, we are not liable for indirect losses such as lost game progress.
Law and disputes
These terms are governed by Portuguese law. If you are a consumer, you keep the protection of the mandatory laws of the country where you live and can go to its courts. To resolve a dispute out of court, you can contact the consumer arbitration centre CNIACC (www.cniacc.pt).
