Privacy Policy

Updated October 7, 2026

What we store

Guest progress and favorites stay in your browser. For accounts, we store your player name, avatar color, sign-in identifiers, favorites, recently played games, and the game saves you sync.

Passkeys and sign-in

For passkeys, we store the public key. Your fingerprint, face data, and device screen-lock secret never reach SiFunly. When an available third-party sign-in is used, we verify its account identifier. Essential security cookies keep your session signed in.

Running the website

Alibaba Cloud and Cloudflare provide hosting, network security, and content delivery. They process network information needed to deliver the site, such as IP addresses and requests. Account responses and saved games are not publicly cached.

Your choices

In Account settings, you can edit your profile, download your data, or delete your account. Clearing browser data removes guest saves. Signing out does not delete cloud saves. Account deletion removes live account data; restricted recovery backups are retained for approximately 14 days before automatic removal.

Feedback

When you send feedback, we store your message, category, game, interface language and submission time. Signed-in reports are linked to your account, included in data exports and deleted with your account. Guests can also submit reports. Feedback is retained for up to 180 days for operational review and improvement. We do not automatically attach screenshots or saved games. Do not include passwords or other sensitive information.

This version

The current version has no commercial advertising or optional audience analytics. If new features change how we process data, we will update this notice.
