Cloud sync folders

Frayo has no cloud or account of its own. Every capture is a plain file in one folder you pick. Pick a folder that iCloud Drive, Google Drive, Dropbox or OneDrive already syncs, and your captures are on every Mac.

Pick the folder

Settings › Library › Folder.

Pictures (the default: Pictures › Frayo), iCloud Drive, Google Drive, Dropbox or OneDrive (a folder named "Frayo" inside it; only services installed on your Mac are listed), or Choose Folder… for any folder.
Frayo copies everything to the new folder, checks every copy, then saves new captures there. The old folder is not changed: delete it yourself in Finder once you have checked the new one. You can cancel while it copies.
On your other Macs, pick the same folder.

What's in the folder

Your captures, as normal files. A project is a subfolder.
A hidden .Frayo folder (lowercase) with, for each capture, an id, which Mac took it, its saved and bookmarked marks, and the file name it links to.
Not the text Frayo reads from screenshots, not the window titles, and not the app, window and page address used for bug reports: those stay on the Mac that took the capture. Search on another Mac works once it has read the text itself, and automatic titles show only on the Mac that took the capture. A name you give a capture is its file name, so it syncs.

If the folder is shared with other people in iCloud Drive, they see every capture and its name. Settings says so.

Two Macs

New captures from another Mac appear in the Library when the sync app delivers them. In iCloud Drive, a capture that is not on this Mac yet downloads when you open it.
Each Mac only ever moves its own unsaved captures to the Trash, so one Mac cannot delete what another keeps.
Renaming or moving a file in Finder keeps its name and saved mark in Frayo (in iCloud Drive; some other services drop that link, and the file then counts as one you added yourself).

Google Drive

Frayo uses the "My Drive" folder of the account. If your Mac uses another language and "My Drive" has a different name, Frayo uses the first folder it finds in that account.

Tips

If iCloud is set to "Optimise Mac Storage", older files download on demand.
If the folder cannot be created, you see "Couldn't use that folder" with the reason.
