Offline-First, Private Diagramming

Your drawings stay on your device

ArchBoard has no accounts and no backend. Scenes are saved in your browser's IndexedDB as you draw, so closing a tab never loses work and nothing is uploaded. There are no third-party trackers, and optional network features, such as searching an online icon set, are off by default and clearly labelled.

What local storage means for you

Browser storage belongs to one browser profile on one device. Clearing site data or using a different browser starts you with an empty workspace. The editor asks the browser to treat the data as persistent and shows when storage is low, but a backup is the only real protection.

Back up and move work

Use the backup action in the scenes panel to download every scene, folder and image as one file, and import it on another browser to restore. Individual scenes can be exported as PNG or SVG with the scene embedded, so the picture itself can be opened again for editing. A periodic reminder nudges you if you have not backed up recently.

Working without a connection

Fonts, icons and the editor itself are served from the same origin, so drawing, exporting and version history work without a network once the page has loaded. Features that need a network, such as an online icon search, fail quietly and never block editing.

Practical habits

Treat the browser workspace as a working copy rather than an archive. Export a backup whenever you finish something important, keep exported files in your normal storage, and name scenes so they can be found by search later. If you share a computer, remember that anyone using the same browser profile can open your scenes, so use a separate profile or clear site data when you are done.
