ONE PIECE Grand Gourmet Cross-Save: Mobile & PC Transfer Limits

The short answer

For ONE PIECE: Grand Gourmet, Bandai Namco says Android and Google Play Games PC cannot share save data. Its App Store and Google Play support pages also say saves cannot be transferred or shared across different devices.

Steam advertises Steam Cloud, but that does not establish transfer support between Steam and mobile or Switch. Those specific cross-store pairs were not verified in this review.

Installing Grand Gourmet on another device does not establish that your restaurant will move with it. The publisher gives specific save-sharing restrictions for the mobile editions and Google Play Games on PC.

Use the exact editions on both devices when checking the answer. Steam and Google Play Games PC are separate releases.

The documented platform cases

Android → Google Play Games PC, or the reverse: the game's official FAQ explicitly says the two platforms cannot share save data.
App Store edition → another device: the official App Store support answer says save data cannot be transferred or shared across different devices.
Google Play edition → another device: the official Google Play support answer gives the same cross-device restriction.
Steam Windows saves: the edition advertises Steam Cloud and publishes a Cloud file configuration. This review has not performed a synchronization test between two Steam devices.
iOS ↔ Android is also a mobile cross-device transfer. The publisher's mobile FAQ restriction applies; no supported exception was established here.
Steam ↔ Android, Steam ↔ iOS, and Steam ↔ Switch: no working transfer procedure or pair-specific official answer was verified here. Keep these cases marked unverified.

Before changing devices or buying another edition

Identify the edition on your current device: Steam, App Store, Google Play, Google Play Games PC, or a console release.
Identify the edition on the destination device. A PC alone does not tell you whether the game is the Steam or Google Play Games release.
Match that pair to the documented cases above. For a mobile cross-device case or Android ↔ Google Play Games PC, plan for separate progress under the publisher's current answer.
Keep the source device and its data intact while deciding. Access to an installation or purchase does not demonstrate that a save has transferred.
For an unverified pair, ask the publisher's support service using both exact edition names. Wait for a supported procedure before replacing files or discarding the source data.

Separate purchase access, Cloud and transfer support

A launch discussion includes players asking about iOS-device cross-save and using an Android purchase on PC through Google Play Games. That conversation is a demand signal; the publisher's edition-specific FAQs are the basis of the restrictions above.

Steam Cloud applies to supported Steam data. It does not prove that another storefront can import the same restaurant. For the configured Windows folder and a separate-copy procedure, use the Windows save guide.

No account-link button, mobile upload menu, save-conversion workaround or exception to the official cross-device answer was established by this research.

✓ How to check the result

You can name the exact source and destination editions and distinguish a documented restriction from an unverified pair.

Keep the original progress available until you have confirmed the intended result. Buying or launching a second edition alone is not a successful transfer.
