First things first: No data will be deleted, and you’ll have full access to everything you expect.
Thanks for bringing this up—I want to be sure there’s no room for misunderstandings: All your data on your device will be merged, and nothing will be lost. You’ll continue to enjoy full access to every feature — including the catalogue, wishlist, band trays, logbook, stats & insights, sharing, and more — whether you’re a new or existing user with a collection.
If your collection already has more than 5 bands, or grows beyond 5 bands, an upgrade will be required before you can add another new band and see the confetti fly! Put simply: If you’re not adding new bands to your collection, technically you don’t need to upgrade to Pro, but there’s no need to hold off updating the app.
A full statement will be available soon.
