留住对话本身，而不只是一份备份。
Message Album 是一款原生 macOS 应用，每次将一段“信息”对话导出为可搜索的私密离线存档：双方的每一条消息、每一个附件，以及一份带校验和的清单。所有数据都不会离开你的 Mac。
What it does
Both sides of the conversation
Not a roll of screenshots. Every message sent and received, in order, with timestamps, attachments and the sender's name where it can be resolved.
Every attachment, at original quality
Photos, videos, voice notes, stickers and documents are copied into attachments/ untouched, not re-encoded or downscaled.
Reads iPhone and iPad backups
Point it at a Finder backup stored on this Mac, encrypted or not, and export a thread that never synced to the Mac's own Messages library.
Names and faces, resolved locally
For one-to-one threads, a phone number or email becomes that person's name and contact photo, read from Contacts on this Mac and embedded only in the export.
Immutable, checksummed snapshots
Each export is a new timestamped folder carrying SHA-256 checksums for everything in it. Re-exporting a conversation never overwrites an earlier archive.
Repeat exports cost almost nothing
When the destination already holds an earlier archive of that thread, byte-identical attachments are cloned rather than copied. On APFS, exporting a large conversation again adds almost no disk.
Warnings instead of silent gaps
Attachments that were never downloaded to this Mac, and Apple-private payloads that cannot be decoded, are recorded as explicit warnings in the manifest rather than quietly dropped.
Built to outlive the app
The exported reader uses no framework, CDN, external font or server, and the archive schema is versioned and independent of Apple's private database format.
