Where do your keys actually live when you use Sidecar? 🗝

Sidecar never sends your keys anywhere. They're stored on your device, encrypted, and the key that unlocks them is derived from the PIN you chose. We couldn't recover it if we wanted to, and that's the point: nothing to breach and no one between you and your identity.

The elegant part of that design is also the honest part: it means the responsibility is genuinely yours.

Two small habits make it effortless:

Back up your keys. Export your nsec, an ncryptsec, or a full encrypted vault, and keep it somewhere outside your browser. A backed-up key can rebuild everything, anywhere.

Keep your PIN somewhere private. A password manager or a piece of paper in a safe place. There is no "forgot my PIN" feature, by design.

Self-custody isn't a feature we added. It's the whole idea.

Stay classy, Nostr. 🍸
