Classified tiers
Health, financial, and casual preference lanes with different encryption and export rules so sensitive data is not flattened into one bucket.
Sovereign storage
Keys, encryption, and audit in one vault.
Vault is encrypted storage with granular permissions, audit logs, and standard exports. It supports BYOK options and enterprise isolation patterns.
Dedicated product site
vault.4stax.comThis product has a dedicated site. If it is not live yet, join the waitlist for updates.
One-click revocation
Disconnect a vendor or integration and cut access without losing your personal archive or scrambling for exports after the fact.
Consent ledger
Append-style record of what left the vault, to whom, and under which purpose so “my data” stops being a black box.
Local-first path
Aligns with kontxt on npm: raw traces and vault stay on disk until you opt into cloud paths.
Encryption you can verify
Client-side options for high-sensitivity tiers and server-side key rotation. Vault contents are never used for model training unless you explicitly opt in.
Per-app and per-team rules
Map OAuth clients and internal services to scopes. See who read what, when, and from which integration, not a single “admin sees all” toggle.
Exit without drama
Scheduled exports, portable snapshots, and documented deletion flows so procurement and security reviews stay straightforward.
