Fydra

Features
Read full description

Fydra is the encrypted vault for everything a password field can't hold. Your password manager keeps your logins. Fydra keeps everything else: the API keys, SSH keys, secure notes, payment cards, bank details, and identity documents that don't belong in a login field, and definitely don't belong in a plain-text note. Everything in Fydra is encrypted on your device with AES-256-GCM before it's ever written to disk or synced. The keys never leave your devices. Fydra has no servers, no account to create, and no way to see your data. Sync runs entirely through your own private iCloud. WHAT YOU CAN STORE • API keys & access tokens, with environment, org, and notes • SSH keys: hosts, key types, and private material • Secure notes for anything that needs to stay secret • Payment cards: numbers, expiry, CVV, billing • Bank accounts: IBAN, routing, account numbers • Identity documents: passports, licenses, IDs • Custom items with your own fields BUILT FOR PRIVACY • AES-256-GCM encryption, performed on-device • Master key stored in the Secure Enclave-backed Keychain, never synced in the clear • Face ID / Touch ID lock • No account, no tracking, no analytics, no data collected • Open, inspectable security model built on pure Apple frameworks, with no third-party SDKs WORKS THE APPLE WAY • Private sync across iPhone, iPad, and Mac through your own iCloud • Native SwiftUI on every platform, including a Mac menu bar app • Folders, favorites and instant search to keep everything organized • Scan a passport, ID or card to fill in its fields, read on your device (with Apple Intelligence where available) • Expiry reminders before a passport, ID, licence, card or membership runs out • Apple Watch app: your favorites and upcoming expiry dates on your wrist • Import from other managers to get started fast FREE TO START Store up to 10 items free, with iCloud sync and attachments included. Fydra Pro unlocks unlimited items and the SSH agent for Mac: monthly, yearly, or a one-time lifetime purchase. Your choice, no subscription required. Fydra is the vault Apple Passwords doesn't try to be, built for the secrets that matter most. Fydra Pro is available as a monthly or yearly auto-renewing subscription, or a one-time lifetime purchase. Payment is charged to your Apple Account; subscriptions renew automatically unless cancelled at least 24 hours before the end of the period, and can be managed in your account settings.
