The Sealed Vault
A message hidden by time and secret
If a trusted person needs access before the unlock date in an emergency, they can bypass the time lock by correctly answering this question — but they will still need the passphrase to decrypt the vault.
Secret Question Secret Answer The answer is hashed with SHA-256 — only its fingerprint is stored, never the raw text.Attachments

The Sealed Vault
A secure, time-locked document vault. Your content is encrypted in your browser before it ever reaches the cloud — no one, not even this app, can read it without your passphrase.
Time Lock
Set a date before which the vault cannot be opened — even with the correct passphrase.
Passphrase
A secret passphrase encrypts all content. Without it, the vault is permanently unreadable.
Emergency Override
An optional secret Q&A that lets a trusted person bypass the time lock — but still needs the passphrase.
File Attachments
Attach PDFs, images, and documents. Each file is encrypted before upload.
How It Works
1Create an account and sign in
2Write your message and attach any files
3Set a passphrase and an unlock date
4Optionally set an emergency override question
5Seal the vault — everything is encrypted in your browser
6Share the Vault ID and passphrase with your trusted person via separate channels
7When the time comes, they enter the passphrase and the vault opens
Sealing a Document
Sealing encrypts your message and locks it until your chosen date and time.
Message Content
Type or paste the text you want to seal. Encrypted with AES-256-GCM before saving.
Vault Name
A memorable label (e.g. "Letter to My Children"). Visible to recipients who look up the vault.
Secret Passphrase
The key that encrypts everything. Share it via a separate secure channel — never in the same message as the Vault ID.
Unlock Date & Time
The earliest moment the vault can be opened. The open button is blocked until this time passes.
⚠ Passphrase Warning: There is no passphrase recovery. If you lose it, the vault contents are permanently inaccessible. Store it safely.
💡 Tip: After sealing, note your Vault ID — you will need it to share the vault with your trusted recipient.
File Attachments
Attach multiple files to any vault. Each file is encrypted with your passphrase before upload.

📊 Excel (.xls, .xlsx)
📋 PowerPoint (.ppt, .pptx)

How to Attach Files
1In the Seal tab, scroll to the Attachments section
2Click the zone to browse, or drag and drop files directly
3Files appear in a list — click ✕ to remove any before sealing
4When you seal, each file is encrypted then uploaded with a progress bar
5After opening the vault, click ⬇ Download per file to decrypt and save it
🔒 Security: Files are encrypted in your browser before upload. Firebase only holds unreadable ciphertext.
Opening a Vault
Two conditions must both be met before a vault can be opened.
Time Lock Lifted
Current date and time must be past the unlock date.
Correct Passphrase
The exact passphrase used when the vault was sealed.
Standard Opening
1Click the Open the Vault tab
2Select your vault from the dropdown
3Confirm the time lock shows ✔ lifted
4Enter the passphrase and click Attempt to Open
5Your message and attachments appear below
Emergency Override (time-locked vaults)
1Expand the ⚠ Emergency Override section
2Answer the secret question
3Enter the passphrase above
4Click Override Time Lock & Open
⚠ Note: The emergency override bypasses the time lock only — the passphrase is always required.
Security & Encryption
No one — including this app — can read your content without the correct passphrase.
Algorithm
AES-256-GCM — military-grade symmetric encryption for both text and file attachments.
Key Derivation
PBKDF2 with SHA-256 and 200,000 iterations — makes brute-force attacks extremely slow.
Where encryption happens
Entirely in your browser via the Web Crypto API. Your passphrase and plaintext never leave your device.
Emergency answer
SHA-256 hashed before saving. The raw answer is never stored anywhere.
Firebase Firestore
Stores vault name, unlock date, and encrypted ciphertext only. Never the passphrase or plaintext.
Firebase Storage
Stores encrypted file blobs only. Permanently unreadable without the passphrase.
Reseal & Rotate
After opening a vault, the owner can change the passphrase, reset the time lock and update the emergency override in one step. All content and attachments are re-encrypted with the new passphrase. The old passphrase becomes permanently invalid immediately.
Two-person principle
For maximum security, give the passphrase to one trusted person and the emergency override answer to a different trusted person. Neither can open the vault alone — both must collaborate in an emergency.
🔒 Zero-knowledge design: Even if Firebase were compromised, your vault contents would remain encrypted and unreadable.
⟳ After emergency access: If your vault was opened via emergency override, consider using Reseal & Rotate immediately to issue a new passphrase and reset the time lock — especially if you believe the old passphrase may have been compromised.
Frequently Asked Questions
What if I forget my passphrase? ▾
There is no recovery. Without the passphrase, the vault contents are permanently inaccessible — even to app administrators. Always store it safely.
Can I change the passphrase after sealing? ▾
Yes — use the Reseal & Rotate feature. Open the vault with your current passphrase, then click "⟳ Reseal & Rotate" in the Vault Management section. You can update the passphrase, time lock and emergency override all at once. The old passphrase becomes permanently invalid immediately.
Can I change the unlock date after sealing? ▾
Yes — use Reseal & Rotate. Open the vault, click "⟳ Reseal & Rotate" and set a new unlock date. You must also confirm your passphrase and set a new one as part of the rotation.
What should I do after emergency access is used? ▾
We strongly recommend using Reseal & Rotate immediately after an emergency override is used. This lets you issue a new passphrase, reset the time lock and update the emergency override — ensuring the vault is fully secured again with fresh credentials.
Can I edit a sealed vault's contents? ▾
No. Once sealed, contents are encrypted and cannot be modified. Delete and re-create if needed.
Can multiple people be trusted recipients? ▾
Yes — share the same Vault ID and passphrase with as many trusted people as needed. Each needs their own account.
Can a trusted recipient delete my vault? ▾
No. Only the vault owner can delete or reseal it. Trusted recipients can only read it.
Is the app available on mobile? ▾
Yes — works in any modern browser on any device. No installation required.
What happens to attachments when a vault is deleted? ▾
Both the Firestore record and all Firebase Storage file attachments are permanently deleted immediately.
Are attachments re-encrypted during Reseal & Rotate? ▾
Yes — every attachment is downloaded, decrypted with the old passphrase and re-uploaded encrypted with the new one. This ensures all vault content is protected by the new credentials.
Is there a storage limit? ▾
Firebase Storage includes 5GB free — far more than enough for personal use. Individual attachments are capped at 20MB each.
