Privacy policy

1. Information collected and its use

Guest play requires no registration. We store cookies, uploaded images and GIFs, character names, share codes, public consent, power, wins and battle history to manage characters, publish them, provide battles and prevent abuse. Battle inputs are sent to the server to verify results.

When a character is added, we store the country code Cloudflare estimates from the connection’s IP to show a country name and flag. This feature does not store the IP itself in the app database. VPNs may affect accuracy; this is not nationality or where the image was generated. Samples use Japan; missing or undetermined countries are shown as unknown.

Battle history stores time, opponent name and image reference, result, departure and power earned, visible to the character owner. Deleting a character also deletes related battles. To deter reward abuse, we compare keyed hashes of IP addresses and browser identifiers. Raw IP addresses are not stored in the database. Matching data is removed on an access after 30 days.

When you log in, we store your email, display name and authentication data. Google login provides account identity information; email login stores a password hash. We use IP addresses, device information and login attempt records to protect authentication. These details are not public.

2. Cookies

Language, controls and guide preferences are saved in this browser’s local storage.

Guest cookies last one year and login cookies last 30 days. Logging in transfers this browser’s guest characters to your account. Your data remains after logout and is available when you log in again. Deleting cookies before login makes guest ownership unrecoverable. Deleting cookies does not delete uploads.

3. Public information

For characters published with consent, other users can view and retrieve images, animation GIFs, names, codes, power, wins and estimated registration country, and use them in CPU battles. Do not include personal information you do not want to publish in images or names.

4. External services

Cloudflare hosts the site and stores data. For communication data handled during delivery and protection, see Cloudflare’s privacy policy. Information entered or uploaded to external image-generation services is governed by those services’ privacy policies.

5. Storage and deletion

Delete a character in its settings after reviewing the warning. Deletion is irreversible. Images and animation GIFs are removed from storage; character data including name, owner association, consent, power and wins, plus battles involving that character, are removed from the database. Image delivery and opponent availability stop, and its share code becomes unusable.

To prevent a code being assigned to another character, only the issued 6-digit number is retained, without character name, image or owner identification. Images and GIFs already saved on other devices cannot be recalled.

6. Policy changes

We update this page when the policy changes. Significant changes to collected information or purposes are announced on this site in advance, with consent requested where required by law. For service conditions, see Terms of use.
