V1 does not require an account and does not accept a Palworld save file. The species you add to “My Pals” are stored in your browser using localStorage.
What is stored
A small list of numeric Pal indexes is stored locally so your roster remains available when you return on the same browser.
What is not stored
The current tool has no user database, payment system, save-file upload, or personal profile. Clearing site data in your browser removes the saved roster.
Future changes
If analytics or save-file parsing are added later, this page must be updated before those features are enabled.
