What we collect
Account email, name, certificate metadata (filename, hash, owner name), and usage statistics. We do not collect file contents in hash-only mode.
Zero-knowledge vault
Vault files are encrypted client-side before upload. Encryption keys never leave your device. We store only ciphertext.
Blockchain data
Only SHA-256 hashes are embedded in Bitcoin transactions or submitted to proof services. Hashes cannot be reversed to recover file contents.
Data retention
Certificates and account data are retained while your account is active. You may request deletion by contacting support.
