_ **Smart Sync — end-to-end encrypted sync for Obsidian, with LAN acceleration** _

_Hi everyone, I’m the developer of Smart Sync. I wanted to share how I approached syncing Obsidian across devices, and I’d love to hear how you use it and what feedback you have._

_The pain point first: I’d jot down a note on my phone, then sit down at my computer and open Obsidian — and still be waiting for it to sync over, with attachments being the slowest part. What I wanted was simple: make an edit and have it arrive near-instantly, no plaintext sitting in the cloud, and no self-hosted sync stack to babysit._

_My approach has three parts:_

1. _ **Encrypt before upload.** Notes are encrypted on your device with AES-256-GCM before being sent to cloud storage — the cloud only ever holds ciphertext. Your login key and your encryption passphrase are two separate keys._

2. _ **LAN acceleration.** When your phone and computer are on the same Wi-Fi, they transfer directly over the local network instead of detouring through the cloud, which makes the first full sync and large attachments noticeably faster._

3. _ **More than notes.** Plugins, settings, themes, hotkeys and bookmarks can each be synced as well, with version history and a recycle bin. New devices join with a 6-digit pairing code._

_Extra features include: password encryption for an individual note, or even just part of a note’s content; folder sorting, with notes pinned to the top or bottom; a standalone search feature; optional launch at startup; and background running. Feedback is very welcome — it directly shapes what gets improved next._

_Your data: stored on Cloudflare R2, end-to-end encrypted — the server stores ciphertext only. The app server runs on Oracle Cloud in the United States._

_Pricing: the free plan gives you 50 MB — get one vault fully syncing first, then decide whether you need more space._

_Install: it’s live in the official Community plugins directory — Settings → Community plugins → Browse, search “Smart Sync” (current version 1.1.8)._
