Start Capsule ↗
STEP 1 · SET UP YOUR SAFE

Pick up to three trusted people—such as a family member, partner, or trusted friend—who should receive your capsule if you stop checking in. Their contact details stay private, and they never get alerts while you are active.

STEP 3 · SAFETY TIMER & RELEASE

Finalize Release Rules
Set your schedule and stay safe.

Set how often you check in (such as once a week or once a month), and choose a grace period for travel or poor cell service. When you are satisfied with your setup, activate the capsule and follow the required check‑in schedule.

CAPSULE FEATURES

Five Locks (Bitty Capsule)

Start Capsule ↗
LOCK 01 · PIN PASSCODE

Pin Passcode
Only those with the PIN can decrypt.

Your capsule is sealed in your browser with AES-256 GCM before anything is saved. The key is derived from your PIN, so without it the contents stay unreadable — to us and to everyone else.

Browser-Enforced AES-256 GCM Zero-Knowledge Vault Works Offline

ENCRYPTION LAYER AES-256 GCM
Sealed locally · PIN required to decrypt
LOCK 02 · EXPIRATION TIMER

Expiration Timer
Choose when it opens — or when it dies.

Schedule the reveal. A countdown can hold your capsule until a future date, release it for a limited window, then lock it away again when time runs out.

Countdowns, Delayed Reveals, Date Ranges Auto-Locks When Time Is Up Nothing Left Behind

LOCK 03 · BURN ON READ

Burn on Read
Single-use contingency drops.

Set the capsule to self-destruct after a single opening. The decryption key is purged the instant it is read, so the link can never be opened a second time.

LOCK 04 · CHAINED LINKS

Chained Links
Box A → Box B → Box C, staged reveals.

Chain capsules together so each one unlocks the next. Perfect for sequenced instructions, staged reveals, or a journey that must be followed in order.

LOCK 05 · VOICE AI

Voice AI
Configured on its own dedicated slide.

Give your capsule a voice. Pick the tone, then let a configurable voice read your final message aloud the moment it is released — the words land harder when they are spoken.

Configurable Voice & Tone Reads Your Message at Release Optional Layer

“Hi — if you are hearing this, it is time. Everything you need is inside.”
