Keep the file beside the moment that explains it.
Premium file attachments place documents and other regular files inside the same private entry or Article instead of leaving their context in another app.

Files become part of the record
DiaryThreads accepts regular files that the system file picker can provide, subject to the documented count and size limits. A private app copy prevents the diary entry from depending on a temporary external file-provider URL.
Files sit beside the text, media, date, replies, and quotes that give them meaning.
Preview where the system can, preserve where it cannot
Supported formats open with the system Quick Look experience. When a format has no inline preview, the file remains available through system share and export actions.
Optional Premium private iCloud sync can carry eligible protected copies between supported devices after the user explicitly enables it.
Adding files is Premium; keeping your files is durable
Premium is checked when new files are added. If Premium later expires, existing attachments remain accessible for viewing, sharing, exporting, and deletion.
Ordinary entries and Articles have separate limits so a long-form record can carry a larger research or project bundle without hiding the boundary.
Questions about this topic
Which file types can I attach?

Are attachments uploaded to a DiaryThreads server?

Will I lose existing files if Premium expires?
No. Existing attachments remain viewable, shareable, exportable, and deletable. Adding new files requires verified Premium.
