Frequently asked questions

Does Prism Forge need an internet connection?
No. Everything — including the Daily Forge challenge — is generated on your device. Airplane mode is fully supported.
Where is my progress saved?
Locally on your device. It is included in your normal device backup, so restoring your iPhone from a backup restores your progress.
I lost my progress after deleting the app.
Deleting the app deletes its local save. Reinstalling starts fresh — there is no account or cloud save in this version.
How do the Daily Forge puzzles work?
Each calendar day seeds one puzzle, the same for every player, generated entirely on-device. Missing a day never punishes you.
Are there in-app purchases or subscriptions?
No. You pay once on the App Store and own the complete game.
Does the game collect any data?
The app collects no data. See the privacy policy for how voluntary support emails are handled.
