Desktop app

The Datyo desktop app shares the same account and cloud capabilities as the web app (Spaces, chat analysis, dashboards, scheduled jobs, and more), and adds local data analysis on top: both files and databases can stay on your own computer or intranet, and raw data is never uploaded to the cloud. Available for macOS and Windows.

Download & install

Version	For	Download
macOS (Apple Silicon)	M-series Macs	Download DMG
macOS (Intel)	Intel Macs	Download DMG
Windows (x64)	64-bit Windows 10/11	Download installer

macOS install:

1. Download the DMG for your chip and open it;
2. Drag Datyo into the "Applications" folder;
3. Before the first launch, complete the one-time unlock below.

Windows install:

1. Download Datyo-Setup-x64.exe and double-click to run;
2. If a blue "Windows protected your PC" prompt appears, click More info → Run anyway (the app is fine, it's just not code-signed);
3. Follow the wizard (choose an install dir; desktop and Start-menu shortcuts are created by default).

macOS shows "'Datyo' is damaged and can't be opened" on first launch?

This is macOS blocking a non-notarized app (the app itself is fine). Fix it once:

Open "Launchpad → Other → Terminal", paste this command, and press Enter:

xattr -cr /Applications/Datyo.app

Then open it normally by double-clicking.

About auto-update

Both the macOS and Windows desktop apps support in-app auto-update: when a new version is available, a prompt appears at the bottom-right; click "Update and restart" to download and relaunch to the new version in-app — no need to re-download the installer.

Not sure which chip you have?

Click the Apple menu (top-left) → About This Mac: "Apple M1/M2/M3/M4" means Apple Silicon; "Intel" means Intel.

Relationship to the web app

• Identical cloud capabilities: Spaces, chat analysis, charts, dashboards, datasets, scheduled jobs, etc. sync with the web app, and data is shared;
• Desktop adds local-data capability (below), which the web app lacks;
• The UI is optimized for desktop: a global left nav (Chat / Datasets / Dashboards), landing straight in chat after sign-in.

Local data: it never leaves your machine

The desktop app can use local files and intranet databases as sources, doing parsing and querying on your own computer:

Local files

Import CSV / TSV / JSON / Parquet / Excel (xlsx, xls) under Datasets → New dataset → Local. Each non-empty Excel sheet becomes its own dataset. Files are parsed and queried by the built-in local engine and are not uploaded to the cloud.

Direct local database connection

Also under the Local tab, choose MySQL or PostgreSQL, enter the connection info → test → pick the tables to analyze. Queries run from the desktop directly over your local network to the database, not through cloud APIs; connection info is stored only on your machine.

How does AI keep data on-device?

Local datasets also support natural-language questions and "AI-generated field descriptions". These two features send only field names and types to the cloud to generate SQL or description text — no data content is sent — and the generated SQL runs on your machine.

Using local data in a Space

A Space's "space data" can reference both local data and cloud datasets, clearly distinguished by badges:

• Data marked Local exists only on this computer; click to open local analysis (overview / sample data / analyze);
• The chat experience is identical for local and cloud: whether you ask about cloud data, a local dataset, or a mix, the same cloud Agent drives the same flow (reasoning → SQL → execute → natural-language read-out → chart). When local data is involved, every SQL the Agent generates runs on your computer (mixed queries download the needed cloud data locally first, then JOIN locally), so local raw data never leaves your machine; aggregated results are sent back to the cloud so the Agent can interpret and chart them;
• Data marked Cloud works the same as the web app and can be analyzed in chat directly.

All data import and creation happens on the "Datasets" page; "space data" only references data that already exists.

FAQ

Is the desktop app paid? The desktop app itself is free; cloud capabilities (AI chat, SQL generation, etc.) are billed per your account's pricing, same as the web app. Local parsing and querying run on your machine and don't consume cloud quota; only generating SQL / field descriptions counts as a normal AI call.

Does local data sync to other devices? No. Local data (file references, database connections, field descriptions) is stored only on the current computer; switching devices requires re-importing.

Is Windows supported? Yes. Download the Windows (x64) installer under Download & install above. It has the same features as the macOS version (cloud capabilities + direct local file / database connection) and also supports in-app auto-update. If SmartScreen blocks the first run, click "More info → Run anyway".
