Chatsward is a UK-based company specialising in WhatsApp evidence for legal purposes: professionally formatted PDF documents with a recorded chain of custody, and DeepCheck, its proprietary digital fingerprint analysis for examining the integrity of an export.
With metadata for legal use
Our WhatsApp PDF service goes far beyond presentation. Each export is given a SHA-256 hash for the chain of custody and an RFC 3161 trusted timestamp fixing exactly when it was uploaded. Its metadata is captured and stored, making it DeepCheck-ready for examination at any later date.
A verification pack accompanies every PDF, and a public portal allows anyone handed the document to check it against our records.

WhatsApp export analysis
DeepCheck scans a WhatsApp export for anomalies. It reads its digital fingerprint and surfaces anything that needs to be reviewed.
A screenshot carries no verifiable provenance. A full examination of the handset is thorough, but slow and expensive. DeepCheck sits between the two: a lightweight anomaly check on the export itself — a broad array of integrity checks across the archive, its media and the chat text — in seconds.
DeepCheck is currently available to registered account holders only.
We prepare and examine. The court decides.
Chatsward reports what an export’s metadata shows and what it is consistent with; what that means for a case is for the court to decide. The same service, and the same findings, set out plainly — whether the reader is a solicitor, an HR team or an individual preparing their own evidence.
Upload your native WhatsApp export and your chat is converted into a paginated PDF, preserving every message, timestamp and image. You receive a SHA-256 hash for the chain of custody, a trusted timestamp pinpointing exactly when you uploaded, and your export is DeepCheck-ready — its metadata locked for future integrity analysis.
Guidance for individuals →Generation establishes a fixed, timestamped baseline — a structural fingerprint and SHA-256 hashes bound to an RFC 3161 token — against which an export's integrity can later be examined. Prepared with disclosure in mind; built to withstand a notice to prove under CPR 32.19. Subscription accounts add DeepCheck and a dashboard that keeps every generation, PDF and report on one record.
For solicitors and firms →Anyone can check a Chatsward PDF against our records — whether we generated it, and whether it has been changed since — without an account.
