Protect seed phrases on iPhone without cloud exposure
UltraLocked keeps seed phrases, private keys, and wallet backups on your device with Secure Enclave-backed protection. No cloud sync. No accounts. No server access.
Common ways seed phrases get exposed
Most people store recovery material in places built for convenience, not high-risk secrets.
Saved in Notes and synced to cloud
UltraLocked keeps it local with no sync capability
Photographed and backed up automatically
Secure camera captures and encrypts without touching Camera Roll
Stored in tools built for convenience, not coercion
Duress mode shows a decoy vault while protecting real data
Exposed during travel, device inspection, or forced unlock
Dead man's switch and self-destruct timers limit exposure window
Backup strategy depends on one fragile copy
2-of-3 Shamir shares let you lose one and still recover
What UltraLocked adds
Secure Enclave-backed protection
Keys are protected by dedicated hardware built into iPhone.
BIP-39 validation
Catch mistakes before saving recovery phrases.
2-of-3 recovery shares
Split recovery into multiple shares so one loss does not destroy access.
Duress mode
Open a decoy vault under coercion while protecting real data.
Reveal delays and self-destruct
Control access timing and destroy data automatically if needed.
Important tradeoffs
UltraLocked is not built for convenience-first storage. There is:
- No cloud sync
- No account recovery
- No PIN reset
- No cross-device convenience layer
That is intentional. If you want a recovery phrase tool that stays local and hardware-protected, UltraLocked fits. If you want easy sync and account recovery, it does not.
