Encrypted sovereign storage with access-controlled sharing and transparency-log provenance. Every upload, every share, every access — Merkle-anchored and independently verifiable. Your files. Your jurisdiction. Your proof.
Files are encrypted in your browser before upload. The server never sees plaintext. Encryption keys are derived from your ECDH-P384 identity — the same key infrastructure used across all ObligationSign verticals.
Share files by encrypting to a recipient's public key. No shared passwords. No link-based access. Recipients must prove key ownership to decrypt. Every share is a governance decision.
Every upload, download, share, and deletion produces a transparency leaf. File integrity is provable without exposing content. Storage operations are auditable by anyone.
Every version of every file is Merkle-anchored. Roll back to any point in time with cryptographic proof that the version is authentic and untampered.
Choose where your data is stored. Jurisdiction metadata is recorded in the transparency log. Prove to regulators exactly where data resides and who has accessed it.
Same Cloudflare Access login, same transparency log, same billing, same key registry. Sovereign Drive is a vertical on the ObligationSign platform — not a separate product.
