Contact Form

For bug reports, it helps to include:

• A screenshot, if possible

Replies may take a few days.

Reporting an inappropriate inn name

If you see an inn name in the rankings or a shadow battle that is offensive, obscene, contains personal information, or is otherwise inappropriate, send us the inn name and where you saw it (ranking week, shadow battle, etc.) through the contact form above. We will review it and rename or hide it as needed.

FAQ

How do I move to a new device?

On your old device, open Settings > Link in the App and link with Apple (iPhone) or Google (Android). Install the App on your new device and sign in with the same account from Link to restore your inn. Transfers between iPhone and Android are not supported yet.

Are there any purchases?

There are no in-app purchases and no gacha. Koban are earned by playing.

Do I lose out if I don't watch ads?

No. Video ads only play when you tap a button yourself, for example to refill the hot water right away. A banner ad is shown at the bottom of the Codex, Rankings, and Bath Report screens.

Does anything drop if I don't open the App for a while?

No. Warlords' stamina never drops over time, and nothing is lost when the hot water is full.

Deleting your account and data

From the App

Open Settings > "Delete Save" in the App. Deleted data cannot be restored.

• If your account is linked with Apple / Google: your server-side account, save data, battle records, and defense party are all deleted, and the Sign in with Apple link is revoked.
• If your account is not linked: your save data is reset to its initial state. To also delete your battle records and defense party on our servers, send us a request as described below.

If you have uninstalled the App, or can't delete from the App

Use the contact form above, state "Account deletion request" in your message, and include the following. We will delete your data within 30 days and let you know.

• Your inn name
• Your device (iPhone / Android)
• If linked, whether it was Apple or Google
• Roughly when you started playing

What we delete: your account, save data (inn name, warlords, progress), battle records, and defense party.

Finalized rankings from past weeks keep your inn name and record. Crash data and advertising data are retained for the periods set by Google (see our Privacy Policy).
