Magpie
Tamper-evident incident journal with encrypted, self-proving exports
新版本 0.5.1
New icon: two chain links, so Magpie no longer looks like Sepia and Blot.
People document disputes with a camera roll and a notes app, and months
later it proves nothing: files re-save, dates shift, entries vanish.
Magpie is an incident journal with receipts:
* Every entry (photo, note, file) is hash-chained to the one before it.
Edit, reorder, or delete anything and the chain breaks visibly.
* Everything is encrypted on your device with your passphrase. Locked
means unreadable, including to the app.
* Exports are plain zips carrying your files, the chain manifest, and a
small python script anyone can run to verify the record without Magpie.
* Share the one-line head hash early (email it to yourself, send it to
someone you trust) and the whole record is pinned to that moment.
This app requests no permissions. Photos come through the system camera,
and the operating system refuses every network connection. No accounts,
no analytics, no dependencies. GPL-3.0-or-later licensed.
Honest limits: tamper-evident is not court-admissible by itself, device
timestamps are claims until anchored, and there is no passphrase
recovery on purpose.
Runs on Android 9 and newer, with Android System WebView 84 or newer.
Android 9 has had no security fixes since January 2022, so on a phone that
old Magpie works, but the phone itself is easier to break into.

新版本 0.4.4
A journal with one entry now says "1 entry", the top bar fits on a phone screen, and Settings shows the version and who made the app. Magpie is now GPL-3.0-or-later.
新版本 0.4.3
Fix: a very large attachment could crash the app. Attachments are capped at 50 MB now, and larger files are refused with a message instead.
