ClosedInk is built on the Base44 platform. Base44 acts as a data processor and maintains SOC 2 compliance for infrastructure security.
Completed signed documents and their audit trails are retained indefinitely for legal validity, unless the Partner or signer requests deletion in accordance with applicable law. Uncompleted envelopes (drafts, expired, voided) may be purged after 90 days of inactivity.
Partner users must provide explicit consent before using ClosedInk for e-signatures. If a user revokes consent, their data will not be used for new signature requests. Previously completed signed documents remain legally valid and are retained per our retention policy. Users may request data deletion by contacting their Partner application administrator or ClosedInk support.
All documents are encrypted in transit (TLS 1.3) and at rest (AES-256). Signing sessions are authenticated via unique, time-limited tokens. Audit certificates include SHA-256 hashes for tamper detection. API access is restricted to Partner-authorized API keys.
