ApiRelay is a private vault for the API keys you use with AI platforms and developer tools. STORE KEYS SAFELY Keep key secrets in the system Keychain. Metadata syncs with iCloud; key secrets sync through iCloud Keychain with end-to-end encryption between your own Apple devices—not uploaded to an ApiRelay server. ORGANIZE & ASSIGN Group by platform or by the tools you use. Assign keys to consumers so you always know which key belongs where. COPY WHEN YOU NEED IT Reveal or copy a secret after optional identity confirmation (Face ID, Touch ID, device passcode, or master password—you choose). Copied secrets can auto-clear from the clipboard after a timeout you set. FREE & ONE-TIME UNLOCK Store a limited number of keys for free. Unlock unlimited keys with a one-time In-App Purchase. Restore Purchases is always available in Settings. PRIVACY-FIRST No ApiRelay account. No analytics SDK. The app helps you keep and hand out keys; it does not send your API calls through our servers. Requires iCloud Keychain on each device that should share the same key secrets.
