Platform imports
Connect Steam, or let Prysm check which games are installed on your Android phone, and your library arrives with hours played. Xbox is coming.
What you see
Prysm shows how many games it found and how many it matched before it asks for anything. Imports always finish in full, so you see your whole library first.
Steam
You sign in on Steam's own page, and Prysm never sees your Steam password. It takes three steps: start, sign in at Steam, then return to the app and finish.

Import
owned games and hours
The app opens Steam, and Steam hands control back through a prysm:// link.
The import reads your owned games and playtime. Steam app ids join to the catalog directly, because IGDB stores them. Where the exact Steam app is an edition or remaster, the import follows IGDB's parent link to the main game. Your Steam profile's game details must be public, and the app explains how to change that when they aren't.
Android
There is no sign-in at all. The app asks Android which games from a known list are installed, on the device, and sends only the matches. Nothing leaves the phone except the list of matched games.
Xbox
Xbox is coming.
How well it matches
About 83 to 85 percent of the games you actually play land in the catalog. That was measured on 14 September 2026 against a real 4,652-game Steam library: 123 of the 148 games ever played resolved.
Across everything owned the figure is much lower, because Steam libraries fill up with bundle and giveaway apps nobody opens. So the app talks about played games.
Re-importing is safe
Reconnecting doesn't duplicate games and doesn't reset your hours.
Limits
Nintendo has no owned-games API, so it can't be imported. The Prysm Pro page covers what happens to a library over the free limit.
