What is technically possible
We do retain conversation metadata for 30 days after confirmed death — participants, timestamps, message counts, attachment hashes (but not the attachments themselves). With a court order specifically authorising the disclosure of metadata under your jurisdiction's equivalent of the Stored Communications Act, NexudeIT can produce that metadata to a court or law-enforcement agency within the 30-day window. After 30 days, all ciphertext is permanently deleted from primary storage, and our backup-rotation cycle purges replicas. That deletion is irreversible.
So — if you need to establish "was my late spouse in contact with this person between these dates?", that's possible with the right legal process inside the 30-day window. If you need to read the conversation, that is permanently and physically impossible.
