Whether you are fixing a stubborn problem or moving to a new device, you can reinstall Stackwallet without losing your wallets, labels or address-book notes — as long as you back up in the right order first.
Two different things are worth separating. Your funds are tied to your keys and recovery seed phrase — restore the seed and your wallets and balances come back. Your notes, labels and address book are convenience data stored locally by the app. The seed restores the wallets; the app's backup and restore feature is what carries over the extra information like labels and notes. Backing up both means you lose nothing.
Check that your recovery seed phrase for every wallet is written down and stored offline. This is non-negotiable and comes before anything else.
Use Stackwallet's backup and restore feature to save your wallet information, including labels and address-book notes, so you can bring them back after reinstalling.
Now uninstall the app, or set up your new device. Because you have your seed and a backup, this step is safe.
Download the official build again from the official site or GitHub releases, and install or extract it as normal.
Open the app, restore your wallets with your seed phrase, and restore your backup to bring back labels and address-book notes. Verify a small balance first to confirm everything is back.
Make sure your recovery seed phrase is backed up offline first, then reinstall the official build and use the restore option. The seed phrase is what recreates your wallets, so a verified backup is the key to losing nothing important.
Notes and labels are local data stored by the app, separate from your funds. Use the app's backup and restore feature to carry over this kind of information, while your recovery seed remains the essential backup for the wallets themselves.
Your recovery seed phrase. Everything else is convenience; the seed is the only thing that can restore access to your funds. Confirm it is written down and stored safely offline before you uninstall or move to a new device.
