Data format and leaving
Where Forsion keeps your data, what format each file is in, and how to open it without Forsion.
Where your data lives
| Where you use it | Notes | AI conversations |
|---|---|---|
| Desktop (macOS, Windows) | A folder you choose (your vault) | A local database on your computer; on our servers when you use a cloud session |
| Forsion Web | Your account's cloud vault | Run and stored on our servers |
| Android | Cloud vault by default; can switch to a local vault on the phone | Run on our servers, or through your own computer |
When you sign in on desktop, the cloud vault syncs to a separate local folder. Your main local vault is not uploaded as a whole.
What each file is
| Content | File | Format |
|---|---|---|
| Notes | .md | Plain Markdown, with properties in the frontmatter |
| Databases | .db | JSON text (not SQLite) holding the columns and every row; calendar events are stored in databases in your vault too |
| Whiteboards | .excalidraw.md | The same format as the Excalidraw plugin for Obsidian |
| Canvases | Still .md | A canvas is a way of showing a note; it can also be exported as JSON Canvas |
| PDFs and images | The original files | Kept as they are in the folder |
AI conversations and agent memory
On desktop, local conversations are stored in a database in Forsion's data folder on your computer (~/.forsion/tangu). Each agent's memory is a set of Markdown files in that folder that you can open and edit. Without an account, all of this stays on your computer; once you sign in, memories and logs sync to your account after each turn.
If you stop using Forsion
- Your notes, databases and whiteboards are all in your vault folder. Copy it; there is no export step.
- AI conversations and agent memory are in Forsion's data folder (
~/.forsion/tangu). Back that folder up too if you want to keep them. - Open
.mdnotes in any text editor or in Obsidian. - Keep drawing
.excalidraw.mdwhiteboards in Obsidian with the Excalidraw plugin. .dbdatabases are JSON text that any text editor or script can read, but the structure is Forsion's own, so other apps will not show them as tables.- When you sign in on desktop, the cloud vault syncs to a local folder that you can copy the same way.
What we collect and how we use it is set out in the privacy policy. More detail is in the docs center under Data and privacy.
