01Where is my data stored?
In the app’s private storage on your device. No Studio501 account is required, the Internet permission is absent and nothing is sent to a Studio501 server.
02What is the daily puzzle?
A puzzle identical for all players on a given date. Finishing each day keeps your streak going.
03Why do hints explain instead of just filling in?
To teach the reasoning: a hint shows why a digit fits a cell. If a digit you placed is wrong, it can also tell you.
04How do I install an update?
For an app installed through Google Play, an update may be offered when the app opens. Follow Google Play’s displayed flow, or update the app from the Play Store as usual.
05How do I ask for help?
