Common questions

Can I move my lineups to a new phone?

Yes. On your old phone, go to Settings and tap "Export a backup", then save the file somewhere like iCloud Drive or Google Drive. On your new phone, go to Settings, tap "Restore from a backup" and choose that file. Your lineups, teams, Playbook and photos will come back, along with any extra slots you got by watching videos. This also works between iPhone and Android.

There is no account, and your lineups are saved only on your device. If you delete the app without exporting a backup, your lineups cannot be recovered.

My purchases are gone (new phone or reinstalled app)

Go to Settings, open "Bokusai Plus" and tap "Restore purchases". If you use the same App Store or Google Play account you bought with, Bokusai Plus and your design packs will come back. Purchases cannot be moved between iPhone and Android, because they are different stores.

I bought Bokusai Plus, but I can't use a design pack

Design packs are sold separately from Bokusai Plus and are not unlocked by it. You can try a pack's designs in the editor, then buy the pack from the finished image screen.

How do I remove the ads, or the Bokusai logo on my images?

Bokusai Plus (a one-time purchase) removes the ads and lets you remove the logo from your images. You can buy it from "Bokusai Plus" in Settings.

I can't add more teams or plays

On the free plan, you can have one team in My teams and one play in the Playbook. Each time you watch a short video, you get one more slot, forever, up to four each. With Bokusai Plus, there is no limit.

I can't save images to Photos

The app needs permission to add images to your photos. On iPhone, open the Settings app, then go to Bokusai > Photos and change the permission. On Android, open your phone's settings, find Bokusai in the list of apps and check its permissions.

How do I change the language?

Go to Settings > Language to switch between English and Japanese. Choose "Use device setting" to follow your phone's language.

How do I change how my data is used for ads?

On iPhone, open the Settings app and go to Privacy & Security > Tracking. In regions where consent is required, such as Europe, "Ad privacy settings" appears under "About this app" in the app's Settings.

I'd like a refund

Payments are handled by each store, so refunds follow the store's own process.

App Store: reportaproblem.apple.com
Google Play: Refunds on Google Play

The app stops or doesn't work as expected

Please send a report from "Report a problem" in Settings. You can check exactly what will be sent before you send it. Your lineups, names and photos are not sent.

Which devices are supported?

iPhone and Android phones. iPad and Android tablets are not supported.
