Question 1

Is it free?

Accepted Answer

Yes. The app, Lua downloads, fixes and your profile cost nothing. Premium is an optional $5/month.

Question 2

Do I need an account?

Accepted Answer

Not to start. Guests get 10 downloads per PC. Log in with Discord and join the server and the cap's gone. Denuvo activations always need the login.

Question 3

What does it do to Steam?

Accepted Answer

It adds the Lua and manifest files Steam needs to show a game in your library. Fixes and online-fixes are separate downloads on the game's page.

Question 4

How do Denuvo activations work?

Accepted Answer

Open the Denuvo Games tab and activate from the app. What you can activate depends on your tier; Premium gives you Bronze for 30 days.

Question 5

What's in Premium?

Accepted Answer

20 MB uploads, an app restyle by the dev, custom profile work, and Bronze-tier activations. $5 or ₹500 a month, approved within 24h.

Question 6

What data do you keep?

Accepted Answer

A hardware ID, IP and your Lua/fix/activation counts, so we can enforce the guest limit and stop abuse. If you log in, your Discord ID and synced library are stored for your profile. Profile and library can be set private any time.

Question 7

What's a profile?

Accepted Answer

A page at vesperdownloader.online/u/yourname with avatar, bio, links, background, music, Discord status and your library. Lay it out however you want with the free drag-and-drop builder.

Question 8

A fix doesn't work. Now what?

Accepted Answer

Post in the Discord. Support and fix requests live there.
