SecureAES-256 client-side encryption. Your words are encrypted on your device before they leave, and by default your password never reaches us — so we can't read them.
Start protecting your wordsThe only platform that combines military-grade encryption with guaranteed future delivery.
All text and media is encrypted in your browser before it leaves your device. By default your password never reaches us — so not even our engineers can open your capsules.
Our automated delivery engine fires at the precise scheduled time — not when someone opens a link, but when the clock strikes.
No monthly fees. No renewal surprises. One payment locks in your capsule until it's time — whether that's next week or 10 years from now.
No credit card needed. Create your first text capsule, set a delivery date up to 30 days away, and we handle the rest.
Dead Man's Switch, Self-Destruct mode, Panic Button, and Surprise Mode — built for every scenario that matters.
