Your app cannot touch anyone else’s
Each app runs in its own sealed container with its own hard limits on processor, memory and processes. A runaway app slows itself down and nothing else.
Safety
Safety and your data
Most of this you should never have to think about. It is here so you can check.
The parts that matter to you
Nothing is exposed directly
No app is reachable except through our front door, which handles the certificates. There is no open port waiting to be found.
Card details never reach your app
Paying always happens on the payment provider’s own page. Your app is not permitted to collect a card number, a CVC or bank details, or to send them anywhere. That is enforced where the app is generated, not checked afterwards.
Your keys are yours
Anything sensitive you supply — a merchant key, a signing password — is stored in your own project, never in our database, and never in a backup of it. We record the name of what you supplied, never the value.
Signing out really signs out
Resetting your password ends every existing session immediately, with no grace window — which is the entire point if you are resetting because somebody else got in.
Uploads cannot become attacks
A file you upload is stored under a fresh name we choose, served with a type we set ourselves, and anything that is not a plain image is sent as a download rather than shown.
And you can always leave
Ask, and you get a single file: your app’s working files, its entire history, and a script that starts it on an ordinary machine with two commands. It does not need us, our tooling or our accounts to run.
That is deliberate and structural. The whole platform is designed to run on one machine with no proprietary pieces on the critical path, which is the same property that makes your copy portable.
