Share Telegram Evidence with Limited Disclosure
Share only what's needed, the original stays untouched.
A handover is a separate signed extract: pick chats and people, hide identities or text, choose files and team notes. The manifest records what was kept, trimmed and left out.
Prepare the recipient's extract
- Exports → Handover extract: write the purpose, pick chats and a period, Load people of the chosen chats if you need named people.
- Everyone else: pseudonyms, left out, or as recorded. Text and files are separate switches; phones and emails can be masked.
- Case Board: nothing, bookmarks and slices, or cards with comments. Team names can be swapped for aliases.
- Download handover extract, open it, verify it, look through it before sending.
One original, a deliberate sharing copy
Synthetic example · identity illustration only
- Select. Include the case chat and identify the person the extract is about.
- Minimize. Choose how another participant appears in the sharing copy.
- Inspect. Open the generated archive's report and records before sending it.
- Share. Deliver the checked copy and communicate its trusted fingerprint separately.

Signed extract

A separate package linked to its source journal boundary
Use the controls together
| Control | Effect on the copy |
|---|---|
| People | Selected people stay named; others get pseudonyms or are left out. |
| Text | All text, only the selected people's and your account's, or none. |
| Files | Files of the selected people and your account, all shown files, or none. |
| Case Board | Nothing, bookmarks and slices, or cards with discussion. |
Read the text and files too: a pseudonym doesn't remove names written inside a message or attachment. If a selected file is missing, restore it or leave attachments out.
