MissCaps — Private Messages, Delivered Only If You Go Missing

Some messages should stay private until the right moment.

MissCaps helps you create encrypted time capsules for the people you trust. Write private messages, add photos or videos, choose recipients, and set your miss days. If you stop checking in past your configured threshold, MissCaps delivers your capsules to your chosen recipients.

It is a private emergency message system for words, memories, and instructions you do not want left unsent.

HOW IT WORKS

Create a capsule — write a private message, add photos or videos, and protect it with encryption.

Add recipients — choose who receives each capsule and set recipient verification.

Check in — use the manual activity button or read articles in the app to record activity.

If you go missing — after your configured miss days, MissCaps sends secure delivery links to your recipients.

Recipients verify — each recipient opens their unique link and verifies before accessing the capsule.

PRIVACY-FIRST BY DESIGN

Your content is encrypted on-device before upload. MissCaps is built so our servers store ciphertext rather than readable plaintext.

• AES-256-GCM content encryption

• RSA-2048 key wrapping

• PBKDF2-SHA256 key derivation

• Privacy PIN protection

• 8 one-time recovery codes for PIN reset if you saved them

• Zero-knowledge server architecture

BLOCKCHAIN PROOF

Blockchain proof on Solana adds a tamper-evident integrity layer.

MissCaps records a SHA-256 fingerprint for capsule integrity verification. Recipients can use the verification information to check that delivered content has not been changed.

SAFER DELIVERY CONTROLS

• Miss days — configure 7, 14, 30 days, or a custom period before delivery triggers.

• Warning emails — receive alerts before your miss-days threshold is reached.

• Secondary Confirmer — designate a trusted person to help reduce false triggers.

• Per-recipient delivery links — each recipient receives a unique secure link.

• Reading articles can count as check-in — a lightweight way to keep your capsules sealed for the day.

RECOVERY CODES

When you set a Privacy PIN, MissCaps generates 8 one-time recovery codes.

If you save your recovery codes, you can reset your Privacy PIN without losing encrypted data. If you lose both your PIN and your recovery codes, MissCaps cannot recover encrypted capsule content for you.
