Safeguards described in the project

✅ Integrity check

Every piece and the finished file are verified with a SHA-256 fingerprint.

🔄 Automatic retry

A piece that fails is retried up to 3 times.

🔍 Gap detection

Missing pieces are noticed and re-requested.

📱 Mobile care

Large files on phones (over 50 MB) are held in on-device storage to avoid memory problems.

📶 Family mode

Warns when a device is on mobile data instead of the shared WiFi.

Why this page is different: the first showcase shows how a person uses the app. This one shows what happens behind the scenes to protect each delivery. Source: project README.
