A Private App Builder. No Cloud.
No account. No cloud. No telemetry. The App Factory doesn't send your work anywhere because there is nowhere for it to go.
Most "private" software is private by policy — the vendor promises. The App Factory is private by architecture: there is no server it could send anything to, because there is no server at all. It's one HTML file running in your browser. Cut the network cable and watch it not notice.
Privacy by architecture, not by promise
A promise can be broken by a policy update, an acquisition, or a court order. A design decision cannot. When the app has no way to reach the internet, no legal jurisdiction and no business model can extract your data from it.
What "no account" means in practice
No signup. No email. No cookies to accept. You open the file and it works — the way a spreadsheet worked before every piece of software decided it needed to know your name.
Where your data lives
In your browser, in the file, on your machine. You can export it to JSON any time. You can back it up the way you back up anything else that matters. Nothing else has a copy.
Frequently asked
Do I need to sign up?
No. There is no signup because there is no server to sign up to. Open the file and use it.
Are there cookies or trackers?
None. No analytics, no pixels, no fingerprinting. The download contains only the app.
Where is my data stored?
In your browser's local storage on the machine you're using. Nothing syncs. Back it up yourself via the export button.
What if the App Factory disappears?
Everything you have already built keeps working. The file is on your disk. You don't need us to keep the lights on.
