Reliquum

Reliquum is a vault for letters across time. Seal a letter, a voice note, a photo, or a video for the person you'll be — in a year, a decade, or the next time you stand somewhere that matters.

— KEY FEATURES —

Seal Compose a letter, record audio, capture a photo or video. Address it to your future self, or to someone else.

Unlock condition Choose a date and time, or pin a place on the map. The relic stays encrypted on your iPhone and unreadable until the moment arrives — even to you.

Reveal When the moment comes, Reliquum guides you through a slow, ceremonial reveal. Hold to break the seal, then read.

Share with someone Seal a letter for a friend, a partner, a child. Hand them the encrypted file through iMessage, AirDrop, Mail, or any share sheet. A short code, exchanged out of band, unlocks the file on their end.

Find what matters A search field, simple filters, and a drafts section let you slip back to a thought from last week without scrolling through a year.

Private by design Everything stays on your device, encrypted with hardware-backed keys and gated by Face ID. No account. No server. No analytics. Optional iCloud Backup (off by default) lets you migrate to a new device — iCloud Drive only ever holds encrypted content.

— USE —

Reliquum is intended for personal use only. It is not intended for professional use.
