How syncing works#

The tablet syncs with Inkhold exactly as it would with Supernote’s Private Cloud: Inkhold speaks the same protocol, learnt by watching a real tablet. Two ways start a sync.

• By hand, from the tablet’s top bar: the tablet walks its folders, compares each file with the server’s, and sends or fetches what differs.
• Auto Sync: the tablet keeps a connection open to Inkhold. It sends each change as you make it, and Inkhold tells it about changes made elsewhere, in the browser or on another tablet, within a second or two.

Deleting syncs too#

The tablet remembers every file it synced. When a file it remembers is gone from the server, it takes that as “deleted in the cloud” and deletes its own copy. So deleting in the browser deletes on the tablet at its next sync, and deleting on the tablet moves the file into Inkhold’s recycle bin, where it can be brought back.

The diagram shows what the tablet does with a file it remembers syncing but can’t find on the server: deleted, unless the server turns out to be a different library.

That rule is why a new or restored server is dangerous to a tablet: every file missing from it would look deleted. Each Inkhold library has its own identity, so a tablet that signs in to a different one forgets what it synced before and starts from scratch, merging and uploading instead of deleting. Copying the tablet first is still the safe way.

Conflicts#

When the same notebook changed on both sides, the tablet keeps both: it saves one under a new name, ending in _CONFLICT_ and a time, beside the other. Nothing is overwritten.

To-Do and Digest#

The tablet’s To-Do and Digest apps sync separately. To-Do sync works and is off until you turn it on; Digest isn’t implemented.
