Storage & backup

Organizer is local-first: there's no account and no server. Your data never leaves your device unless you export it. This page explains where it's kept and how to keep it safe.

Where your data lives

Organizer stores your timelines automatically on this device — there's no setup step and nothing to choose. It uses the Origin Private File System (OPFS) when your browser supports it, falling back to IndexedDB otherwise. Either way:

• ✅ Nothing to set up — Organizer just works the moment you open it.
• ✅ Works fully offline.
• ⚠️ Tied to this browser on this device. It is not synced to other machines, and clearing your browser's site data will remove it. Keep exports as your safety net.

Settings → Backend shows "App storage on this device," and Clear all data wipes it if you ever need a clean slate.

Backing up with Export / Import

Export is how you make a portable backup.

Export

Settings → Backup → Export downloads all your data — timelines, entries, and attachments — as a single JSON file. Keep it somewhere safe.

Organizer shows a gentle "No backup · Export now" nudge in the header if you haven't exported in over a week.

Import

Settings → Backup → Import, choose a previously exported .json file, then pick how to bring it in:

• Replace all data — wipes current data and restores the file exactly. Use when recovering a backup or moving to a new device.
• Merge (skip duplicates) — adds anything from the file that you don't already have, leaving your existing data untouched. Use to combine two sets of timelines.

WARNING

Replace all data is destructive — it discards whatever is currently stored. If in doubt, export your current data first, then import.

Moving to a new device

1. On the old device: Settings → Backup → Export.
2. Transfer the JSON file to the new device.
3. On the new device: open Organizer, then Settings → Backup → Import → Replace all data.
