Changelog

Every release of Synclet. A version is year.month.release — 2026.8.1 is the first release of August 2026 — so the number tells you how old your build is at a glance.

2026.8.1

The first release, and an early one.

What it does

SFTP and WebDAV. An SFTP server’s host key is pinned the first time Synclet sees it, and if it ever changes the run stops rather than carrying on — on a home network, a key that changed by itself is exactly what an interception looks like. WebDAV covers Nextcloud, ownCloud and anything generic.

Pairs: a folder on the phone, a folder on the remote, and a direction — upload or download. The local folder is granted through the system picker, so Synclet never asks for a storage permission and the grant survives a reboot.

Addresses that follow the network. A remote is not one address: your NAS is one thing at home and another from outside. Synclet keeps a list and uses the first that answers, which it works out by trying to connect — no location permission, no reading the name of your Wi-Fi. When nothing answers, the run is postponed, not failed: a NAS you cannot reach from a café has not gone wrong.

A schedule that says what it means. Android’s floor for background work is fifteen minutes and Doze can stretch it to hours. Synclet tells you that where you pick the interval, instead of promising a cadence the phone will not honour.

A dry run, which is where you should start: it lists what would move before anything does.

What it deliberately does not do yet

Nothing is ever deleted — not on the phone, not on the remote, whatever you configure. Mirroring is only safe with the guards that go with it: a first run that never deletes, and a stop-and-ask when a run is about to remove a large part of the target. An unplugged drive and “I deleted everything on purpose” look identical to a sync engine, and only one of the two is recoverable. It arrives when those guards do.

Two-way sync waits for the same reason: telling new on this side from deleted on the other needs a memory of the last run, and without it two-way loses files.

Also not here yet: SMB, SCP, FTP, the cloud providers, and exact scheduling.

Small things that matter

A file modified in the last thirty seconds is skipped — it may still be being written. Uploads land under a temporary name and are renamed once complete, so a half-written file never appears under its real name. Passwords live in an encrypted store of their own and are left out of backups.
