Introduction
Keeplas is a life-continuity platform: a zero-knowledge vault that secures the digital and physical assets your loved ones will need if you ever cannot give them yourself.
Most "digital legacy" tools store your data in a way the provider can read. Keeplas does the opposite. Everything is encrypted on your device before it reaches our servers, and the keys never leave you. Even if our infrastructure were fully compromised, your vault stays sealed.
What you can do with Keeplas
- Store anything sensitive — credentials, documents, financial records, legal papers, health information, and free-form notes, organized into eight categories tuned for inheritance.
- Run a proof-of-life protocol — Life Check pings you on a cadence you choose (weekly, monthly, or quarterly) over WhatsApp and email. If you stop responding, your plan activates — but only after your trusted contacts confirm and a 72-hour grace period passes.
- Distribute access without a single point of failure — Social Recovery splits your master key into 5 shards across trusted contacts with Shamir Secret Sharing. A quorum you set (2-of-5 by default) can rebuild access; no single person ever can.
- Leave video and audio messages — encrypted recordings delivered to specific people on specific dates or life events.
How the architecture protects you
Every item is sealed with AES-256-GCM in your browser. The encryption key is derived from a 24-word recovery phrase via Argon2id — a memory-hard KDF that resists offline brute force. Keeplas never sees the phrase, never sees plaintext, and never holds anything that could unlock your vault on its own.
For inheritance, the master key is split with Shamir Secret Sharing into 5 shards. Each shard is wrapped with ML-KEM-768 (NIST FIPS 203, post-quantum), then sent to a trusted contact. Below the quorum, the shards reveal nothing — not even Keeplas plus a single contact can open your vault.
Who Keeplas is for
- Individuals putting together a real digital continuity plan for their family
- Couples and families coordinating shared finances, documents, and instructions
- Power users who want to verify, audit, or self-host the entire stack — Keeplas is AGPL-3.0 and the repo is public
