Yes. There are no ads, no subscriptions, and no in-app purchases. Coins in the game are play money and can't be bought with real money.

Ages 7–17. When your child enters their age, Dimefinch unlocks lessons made for their age group (7–10, 11–14, or 15–17). Older kids can still replay the younger lessons.

Tap the 🔒 lock in the top-right corner of the home screen and answer the math question. There you can see your child's progress, change their age group, check for updates, or reset progress.

Open the grown-ups area (🔒 on the home screen) and tap the correct age. Lessons update right away, and no progress is lost.

No. Dimefinch has no accounts, ads, or tracking. The nickname and progress are stored only on the device. See our Privacy Policy.

Not yet. Because we don't collect any data, progress lives only on the device it was created on. Deleting the app or switching phones starts a fresh game.

We speed up interest so kids can watch compound growth happen in days instead of years. The app explains that real banks pay interest per year, usually much less.

New lessons and fixes download automatically when the app opens. Your child may see a "New stuff is ready!" banner. Tap it to restart into the new version. You can also tap Check for updates in the grown-ups area.

In the grown-ups area, tap Reset all progress. This erases coins, lessons, and items on that device and can't be undone.

No. Market Mania uses made-up companies and play money to teach ideas like risk and diversification. It is not investment advice.
