Your life deserves a plan. One Inheritance makes sure nothing is lost. If something happened to you tomorrow, would your family know where everything is β€” your bank accounts, insurance, investments, property papers, passwords? Every year, fortunes go unclaimed simply because the people left behind never knew they existed. One Inheritance is a privacy-first digital vault that keeps everything that matters in one secure place β€” and makes sure it reaches the right people, at the right time. ZERO-KNOWLEDGE SECURITY Your data is encrypted on your device before it ever leaves it. We can never see your passwords, documents, or photos β€” not even if we wanted to. ORGANIZE YOUR DIGITAL LIFE β€’ Assets β€” Bank accounts, FDs, insurance, mutual funds, crypto, property β€’ Liabilities β€” Loans, credit cards, and subscriptions your family should know about β€’ Responsibilities β€” Bills, EMIs, and recurring obligations that need handover β€’ Memories β€” Letters, journals, photos, and video messages for the people you love CHOOSE WHO INHERITS WHAT Assign specific items to specific loved ones. Leave personal video messages. When the time comes, access is granted only after their identity is confirmed with face verification β€” so everything reaches the right person, and no one else. A SAFE, VERIFIED HANDOVER No guesswork, no premature access. If you ever stop checking in, One Inheritance first reminds you β€” by notification, email, and SMS. Only if that window passes are your loved ones notified, and your vault is released only after an official death certificate is submitted and reviewed. A single check-in or sign-in cancels the process instantly. STAY IN CONTROL, ALWAYS Set your own check-in schedule. Nothing happens while you're active. You're always one tap away from stopping any handover already underway. BUILT FOR REAL LIFE β€’ Face ID & Touch ID for instant, secure access β€’ PIN fallback when biometrics aren't available β€’ Push notifications for check-in reminders and security alerts β€’ Multi-device support with session management YOUR PRIVACY IS NON-NEGOTIABLE One Inheritance is built on a true zero-knowledge architecture. Your encryption keys never leave your device. Our servers store only encrypted data we cannot read. No ads, no tracking, no compromise. Start protecting your legacy today. Your future self β€” and your loved ones β€” will thank you.
