Great question, thank you!
Yes, almost all wallets let you export an "Excel" file with labels – but please, use an open-source spreadsheet like LibreOffice Calc instead of Microsoft, open-source everything is the rule!
I’ve heard great things about Blockstream Green: the latest version (2025) ties your personal labels directly to the seed, so you find them on any device. It’s multi-platform and includes a simple yet effective 2FA with multisig – perfect for securely holding medium-value amounts even on a hot wallet.
No KYC, all tied to your private keys.
For the rest, pretty much every solid wallet (e.g., Electrum, Sparrow, BlueWallet) now has this label-saving feature, always non-custodial.
For extra security, you can periodically save all your transactions locally...
If you're already using a non-custodial wallet – which is essential – it probably already has this feature built-in! Let me know if you need help!
