Celatum Reviews & Product Details

Celatum is a desktop application designed to detect and anonymize personal data within documents, operating entirely on the user's local infrastructure. Tailored for professionals such as lawyers, fiduciaries, and healthcare providers who are bound by strict confidentiality obligations, Celatum ensures that sensitive information is processed securely without reliance on cloud services. The application employs an AI-powered detection system capable of identifying over 50 types of personal identifiers, including names, email addresses, social security numbers, physical addresses, phone numbers, IBANs, and dates of birth. This comprehensive detection runs efficiently on standard CPUs, eliminating the need for specialized hardware like GPUs. A key feature of Celatum is its pseudonymization capability. It replaces real identifiers with consistent, document-scoped placeholders (e.g., "Person A," "Organization 1"), preserving the readability and coherence of the document while masking actual identities. For workflows requiring reversibility, Celatum allows users to export pseudonym key files, facilitating the restoration of original data when necessary. Celatum supports a variety of file formats, including Word (.docx), PDF, Excel (.xlsx), plain text, Markdown, and CSV files. Users can process individual files or batch entire folders, with the output maintaining the original format and ready for filing, sharing, or publication. Operating entirely offline, Celatum ensures that documents never leave the user's device. This design eliminates the risks associated with data transmission to third-party servers, making it suitable for air-gapped environments and aligning with data protection regulations such as the Swiss Federal Act on Data Protection (FADP) and the General Data Protection Regulation (GDPR). The application provides a review and control interface, allowing users to examine each detected identifier before any changes are applied. Users can enable or disable specific findings, add custom terms, and adjust labels, granting full control over the anonymization process. For scenarios requiring the reversal of anonymization, Celatum offers de-pseudonymization. By utilizing the key file generated during pseudonymization, users can restore original identifiers. This key file remains on the user's device and is accessible only by the user, ensuring secure and reversible anonymization suitable for internal reviews, legal proceedings, or audit trails. Built with privacy by design, Celatum ensures that document processing remains compliant with data protection laws. No data transfer occurs, and there is no involvement of third-party processors or cross-border data flows. Additional security measures include secure memory zeroing, AES-256 encrypted license data, an append-only audit log, and the absence of telemetry. Celatum also supports the creation of reusable templates. Users can save pseudonymized documents as .piia templates, which can later be repopulated with real or alternative data. This feature is particularly useful for court filings, case studies, and recurring document workflows. In terms of security, Celatum has been independently assessed. Following a penetration test conducted in June 2026, OneConsult AG, a cybersecurity firm based in Zurich, issued an independent security statement in July 2026, affirming the application's robust security posture. Overall, Celatum offers a comprehensive, secure, and user-friendly solution for professionals seeking to anonymize sensitive documents without compromising data privacy or compliance requirements.
