01

Local ID

Your browser generates a random 32-hex chain ID and stores it locally. No server involvement. No fingerprinting.

02

Session Log

Each transfer creates a ledger entry with route, file types, sizes, and SHA-256 hashes. Never filenames or contents.

03

Hash Chain

Each record includes the hash of the previous record, creating a tamper-evident, append-only chain backed by a Durable Object.
