I have used anki signed out for multiple months, but got the app and need to sync my data. If I sign in on my laptop now, will I lose my data and progress?Before posting, please do the following
If you just have one collection on one device, see: Cloud Sync - AnkiMobile Manual . For the first-time one-way sync, you’ll be able to choose which “direction” to sync (which collection to keep).
If you have different collections on your devices, you’ll need to preserve one of them so it isn’t overwritten while you’re setting up syncing. Syncing with AnkiWeb - Anki Manual
