NavoOS is your personal digital legacy vault — a private, encrypted space where you store the files, documents, and memories that matter most, and choose exactly who receives them when you're gone. STORE WHAT MATTERS Upload photos, videos, audio recordings, documents, written notes, and location memories into your encrypted vault. Everything is protected with AES-256 end-to-end encryption — not even NavoOS can read your files. CHOOSE YOUR KEYHOLDERS Assign trusted people as keyholders — the individuals who will receive your files after you pass. Control exactly which files each keyholder can access, so the right people get the right things. SET UP VERIFIERS Add verifiers — trusted contacts who confirm your passing before your vault is unlocked. This two-layer system ensures your files are only released at the right time. INACTIVITY TIMER Set a personalised check-in schedule. If you miss a check-in, NavoOS sends reminders. This protects against accidental release while ensuring your legacy reaches your loved ones when it truly matters. EMERGENCY VAULT Store instant-access files for medical emergencies or urgent situations — accessible to your designated emergency contact without waiting for verification. PRIVATE JOURNAL Write private notes, memories, and messages for the people you love. Your journal entries are end-to-end encrypted and shared only with the keyholders you choose. AI LEGACY GUIDANCE Receive personalised suggestions for strengthening your digital legacy, based on your profile. —— All files are encrypted on-device before upload using AES-256. NavoOS servers only ever store ciphertext — your files are never readable by our team. Free plan: 10 vault files · 1 keyholder · Inactivity timer · End-to-end encryption Pro plans: Unlimited files · Multiple keyholders · Emergency vault · Private journal Privacy Policy: https://navoos.com/privacy Terms of Use: https://navoos.com/terms

Verdict
The clearest difference is in-app purchases: NavoOS at none against Send Fax App's 3. NavoOS also leads on ads (none vs shown) and update cadence (every 2 days vs monthly). On price, device support and iOS requirement there is nothing between them.
