LastingNote vs Dead Man's Switch

What would you say to the people you love if you knew they'd only read it when you're gone? LastingNote makes sure your most important messages reach the right people at the right time — automatically, securely, and privately. WRITE WHAT MATTERS Compose messages for the people who matter most. Add photos, documents, voice notes, or just your words. Schedule them for a future milestone — a birthday, graduation, or anniversary — or set them to deliver automatically if you stop checking in. HOW IT WORKS 1. Write your messages and choose your recipients 2. Set your check-in schedule 3. Check in regularly — tap the app, reply to an email, or let your computer handle it 4. If you miss your check-in window, your messages are delivered to your loved ones MILITARY-GRADE ENCRYPTION Your messages are protected with the same encryption used by security professionals — ChaCha20-Poly1305 with Argon2id key derivation. Choose between two security modes: • Guardian Mode — Maximum privacy. Your messages are end-to-end encrypted on your device, and only a Trusted Guardian you designate can authorize delivery. Not even LastingNote can read them. Cryptographically impossible to decipher without the Guardian's passcode. • Automatic Mode — Fully encrypted and guaranteed to arrive. Your messages are protected at all times and delivered automatically when needed, with no extra steps required. SCHEDULED MILESTONE MESSAGES LastingNote isn't just for emergencies.

Dead Man's Switch checks that you're OK. Choose how often you'll check in, anywhere from once a day to once a year. Miss your deadline and your phone reminds you. Still no check-in after the grace window, and the people you chose get an email with the message you wrote. It's for anyone who lives alone, hikes or travels solo, has a health condition, or wants the people who care about them to know if something is wrong. CHECK IN WITH ONE TAP • From the app, a widget, a notification, Siri, Control Center or the Action Button • On Apple Watch: see the time left on your watch face and check in from your wrist • A live countdown shows exactly how long you have, down to the second • Every check-in is confirmed by our server, so what you see is what will happen • Every day by a set time: pick a time, say 9 PM, and that's your deadline every day. Checking in early doesn't move it KNOW WHAT HAPPENS, AND WHEN • See when your contacts would be emailed, and who • Reminders every day and before your deadline • A grace window before anyone is emailed • Send a test email so your contacts know what to expect • If you check in after an alert went out, your contacts get an "all clear" email YOUR MESSAGE, YOUR PEOPLE • Write one message for everyone, or a personal one for each person • Your contacts don't need the app. They just get an email • When you add someone, they get one short heads-up email from us, so a real alert is never a surprise (you can switch it off) TEXT ALERTS (US AND CANADA) • Your contacts can get a text as well as the email, once they say yes with one tap • Texts come in small packs. Emails are always free AWAY MODE • Going somewhere without signal? Pick the day you're back, and nobody is emailed before then PRIVATE BY DESIGN • No account to create • No location tracking Available in English, Spanish, German, Polish, French, Italian and Dutch. Dead Man's Switch is not an emergency service and does not contact emergency services. If you are in danger, call 911 or your local emergency number.
