A program that stays onIt doesn't open any strange windows: it switches on a private address inside your Wi-Fi, and that's the address you open on your phone.
STC Prime · Software que Trabaja en tu Casa
Download it free.
Make your first item inside.
It installs in a minute, you pair your phone and you watch a whole item come out. If you like it, the first month of any plan is €1 (≈ $1.08 — billing runs in euros; the dollar figure is approximate and varies with the exchange rate), paid inside the program itself, not here. Cancel whenever you like.
What you need
Three things. None of them new.
-
A Windows computer you can leave switched on.
It's the one doing the work while you take the photos. It doesn't need to be new: if it can run a browser, it can run this.
-
Your phone on the same Wi-Fi.
Your phone is the camera. There's no app to install: it opens an address, you enter a code and you're in.
-
Your own account for the photo processing.
It's the BYOF model (bring your own fuel): we supply the engine, and your rental only supplies the fuel, at cost with no markup from us. We've already chosen and tested the provider; there's nothing to look for. You connect it once, in Settings, the program walks you through it in a few minutes, and the connection stays encrypted on your computer. You see the month's total on your screen.
What it is
Not a website. Your own workshop.

You shoot. It changes the room.Your photos come in over Wi-Fi. The item that comes out is yours: the logo, the colour, the creases, and the stain if there is one. The only things replaced are the floor and the light.

And along the way, it calculates the priceWhile it builds the photos, it works out what that item costs new in your country and gets a second-hand price from that, and writes the title and the description for you. Back on your phone, everything's there with its own copy button.
Where your photos travel
From your phone to your computer. Without passing through us.
This is the whole route, with nothing hidden. Your phone talks to your computer over your own network, like sending something to the printer at home. The photo processing is done through the GPU rental, not ours: not a single photo reaches us.

All that comes up here is one number: how many items you've done this month.
Not a photo, not a price, not a brand name.
That's why it works in a warehouse with modest Wi-Fi: all that crosses your network is five photos, already shrunk on the phone, and a listing.
Day one
From download to your first listing.
You do it once and never touch it again. The times are the real ones, not the ones that sound good.
-
Open the file you downloaded 1 min
It's an installer: next, next, done. The first time, Windows will ask whether you trust it; exactly which button to press is explained below.
-
The program opens and shows you two things right away
An address like 192.168.0.14:8000 and an eight-character code. The window stays open: it's the one that receives the photos, so it doesn't close while you work.
-
Connect your provider once
It's who supplies the fuel for the photo compute: you pay it to them, at cost with no markup from us, and you see it on your screen. Which one, we've already decided: a reliable one, the one every item on this site was made with. The program walks you through it in Settings, it takes a few minutes and it's not repeated; the credentials stay encrypted on your computer. Without this, it receives photos but builds none.
-
Open that address on your phone and type in the code 30 sec
Once, and for good, on that phone. The code is there so nobody else on your Wi-Fi can open the address and see your items. And to keep it handy: Share → Add to Home Screen. Now it's just another app.
-
Pick up an item and take its photos 2 min
Laid flat on the floor, shot from above. Front, back, the neck label, and the tape measure across the width and along the length. One more only if the item has a flaw to show. The program reads the size off the label and the measurements off the tape; all you choose is the condition.
-
Hit send and move on to the next one no waiting
This is the part where you don't stand around watching. The computer gets on with that item while you photograph the next one, and it chains them together on its own. The app shows you which step each one is at.
-
Back on your phone, it's ready a few minutes
The five photos, each with a button to save it to your gallery, and the title, description and price, each with its own copy button. Open Vinted, paste, publish. Next.
What it doesn't do
Three things it refuses to do.
It's not that it can't: they're off-limits on purpose, and they're what makes a buyer trust the rest of the listing.
-
It doesn't hide flaws
If the item has a stain, the stain shows in the photo. A buyer who sees it declared trusts everything else; a buyer who finds it when opening the parcel sends it back.
-
It doesn't make up measurements
The number the buyer sees is the one on your tape measure, in your photo. No one estimates it by eye. If you don't take the measurement, that number doesn't exist.
-
It doesn't promise the item will sell
The price is estimated from retail value and the second-hand proportion in your country (across 114 countries, without consulting any website). It is a realistic market benchmark, not a chance of selling that nobody can know.
Windows Defender SmartScreen Notice
Does Windows tell you the file is suspicious?
What you download is a clean and secure installer: a single file, Instalar-STC-Prime.exe. Double-click it, click Next through to the end, and STC Prime is ready, with a shortcut on your desktop. Nothing to unzip.
When you open it, Windows shows a blue screen that says “Windows protected your PC”. That's completely normal, and it happens to any new independent program that doesn't have a paid commercial certificate yet: it isn't a virus and poses no risk. Here's how to get past it in two quick clicks, and only the first time:
1
1. Click “More info”
On the blue warning screen, click the underlined link that appears below the main text.
2
2. Click “Run anyway”
A new button will appear at the bottom right. Click it and the installer will start right away.
Windows protected your PC
Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.
App: Instalar-STC-Prime.exe
Publisher: Unknown publisher

2nd click
Run anyway
Don't run
If your antivirus (Windows Defender, Avast, AVG...) asks too, click Allow. It only happens the first time and won't appear again.
Before it happens
It downloads compressed, and the first time macOS will ask you something.
It's a compressed folder, not a single file. Double-click what you've just downloaded to unzip it: STC Prime.app appears inside.
And when you open it, macOS will show a warning. That's normal, and it happens to any program that doesn't come from the official store: it isn't a virus. Here's how to open it, and only the first time:
- Don't double-click. Right-click (or Control-click) STC Prime.app and choose Open.
- On the warning that appears, click Open again.
Something stuck? Write to us from Settings → Help, inside the
program, and we'll look into it.

The challenge
Don't take our word for it. Check it on your disk.
Everything this site says fits into three steps you do yourself, free, on your own machine. Not one of them goes through our servers.
-
01 · Download it to your disk.
The program, free, with no account and no card. A single file that stays on your computer. Without the provider connected it receives photos but builds nothing: it tells you so itself.
-
02 · Process a real item.
Five photos from your phone. We supply the engine; your rental only supplies the fuel, at cost with no markup from us. What gets spent, you see on your screen.
-
03 · Look at the result on your hard drive.
The folder, the five photos, the listing and the price, and the receipt for what you've spent at the GPU provider. Every number on this site is right there, in ordinary folders, for you to measure yourself.
If it doesn't win you over, close the program and that's that. You owe us nothing, and your photos have never left your home.
