Frequently asked questions

Clear answers about privacy, encryption, signing in, and how Armory Atlas protects your data.

Security & Privacy

How is my data protected?: All data is encrypted on your device using a Master Encryption Key (MEK) derived from your Master Password. We never receive or store your raw data — only opaque encrypted blobs. Even if our servers are breached, the data would remain unreadable without your MEK.
What encryption algorithms are used?: Our design uses modern, widely-accepted primitives: a memory-hard KDF (Argon2) for deriving the MEK, and AES-256-GCM for authenticated encryption of data. Keys are stored in platform secure storage (Keychain / Keystore) when biometrics are enabled.
Can you recover my data if I forget my password?: No. Because we follow a zero-knowledge model, we cannot decrypt your data without your Master Password or Recovery Key. During onboarding you receive a 24-word Recovery Key — store it safely. If both are lost, data cannot be recovered.

Can I sign in with Google?: Yes — we support Google Sign-In for convenient authentication. Google handles authentication, but encryption is still controlled by a separate Master Password you create. The Master Password is used only for client-side encryption and is never shared with Google or our servers.
If I use Google Sign-In, do you still require a Master Password?: Yes. Google simplifies authentication, but to preserve the zero-knowledge model you must create a Master Password to derive your MEK. This separation keeps your data unreadable by the server or any third party.

Is the app installable?: Yes. Armory Atlas is a Progressive Web App (PWA). You can install it to your home screen for a native-like experience. The site includes a web manifest and a service worker to support offline usage.
Will the app work offline?: Yes. The app is fully functional offline for your locally stored data. Sync operations (if enabled) will resume automatically when you're back online.

How does the Travel Co‑Pilot protect me when traveling?: The Travel Co‑Pilot cross-references your logged firearms, magazines, and ammunition against a structured database of state laws. For any route, it creates a plain-language checklist describing how to legally transport or stow firearms through each state on your trip.
Can I backup my data to the cloud?: Yes — cloud backup is an optional premium feature. Backups are encrypted on-device with your MEK before upload; the server stores only encrypted blobs and cannot read your data.
Is there a limit on the number of firearms I can log?: The free tier may limit the number of items; premium (Atlas Tier) removes limits and unlocks route analysis and encrypted cloud sync.
