Who we are

Yourdoku is a free web game of short deduction mysteries. You can play without an account. You only need one to create and share your own mysteries or to keep your progress on several devices.

The name and contact details of the person or company responsible for Yourdoku will be added here before launch.

What we collect

• Your Google account basics if you sign in: a user id, your name and your email address.
• What you create: the story line, suspect names, short descriptions, photos you choose to upload, your own clues and your settings.
• Optional secret details about your suspects that you enter in the Studio (such as age or favourite team): they are stored with the case, used only to create and check clues, and never shown to players.
• Your game progress if you are signed in: notes, hints used and results.
• Reports you send about a case.
• Simple usage counts without personal content (for example “a mystery was created”, with the language and whether it was a phone or a computer).
• A pseudonymous code made from your internet address, only to stop abuse such as too many attempts in a row.

Why we use it

• To run the game: show cases, check answers and save your progress.
• To create and share your mysteries, including writing the story text.
• To keep Yourdoku safe: review public cases and photos, handle reports and prevent abuse.
• To improve the game with anonymous counts.

We do not show ads, we do not sell your data and we do not use it to build advertising profiles.

Services that help us

• Google Firebase Authentication handles “Sign in with Google”.
• Cloudflare runs the website (Cloudflare Workers) and stores the data (Cloudflare D1 database), including uploaded photos.
• Cloudflare Workers AI writes the story text (title, introduction and descriptions) and screens text for harmful content. It receives the story line, names and descriptions, never the answer. Your photos are not sent to the AI.

These providers may process data in other countries under their own data protection terms.

What stays on your device

Your browser keeps some things locally: the language you chose (a small cookie), your progress as a guest, your play history, a draft of the mystery you are creating and whether you finished the tutorial. Sign-in also stores a session in your browser. We do not use advertising or tracking cookies.

You can delete this local data at any time from your browser settings.

How long we keep it

We keep your account, mysteries and progress while your account exists. Reports and moderation records are kept as long as needed to keep the service safe. Abuse-prevention codes are kept only for a short time. Exact periods will be confirmed before launch.

Your choices and rights

You can see and change your mysteries in your library, archive them or make them private at any time. You can ask us for a copy of your data, to correct it or to delete your account and everything linked to it. Depending on where you live, you may also have the right to object or to complain to your data protection authority.

Children

Anyone can play without an account. To create an account, you must be old enough under the law of your country, or have permission from a parent or guardian. Never upload photos of children without their guardian's consent.

Contact

A contact address for privacy questions will be published here before launch. Until then, you can use the Report button on any case.
