Common questions
Where is my Practice progress saved?
Progress is saved on the device you practice on. It doesn't move between devices, and it isn't sent to us. To start over, open Practice and use the Reset progress button. Clearing your browser's website data or deleting the app also removes it.
Which iPhones can run the 345pi app?
The iPhone app needs iOS 15 or later.
Do I need an account?
No. 345pi doesn't use accounts or sign-in, so there is no password to reset.
How do I report a wrong answer or a bug?
Email info@345pi.com with the page or problem you were on, what you expected, and what happened. Tell us whether you were using the website or the app, and on which device. A screenshot helps.
