Tinyfit: Kids Jigsaw Puzzles

Tinyfit is a learning game for kids ages 5 to 8 with jigsaw puzzles, sudoku, and word search. Made for kindergarten through 2nd grade, it's a good fit for early readers who are still learning letters and numbers: every digit, letter, and word is read aloud, so your child can play on their own.

Everything on screen is big, and every tap does one thing. No reading is needed to start a puzzle.

THREE GAMES
Jigsaw: a cheerful cartoon picture is cut into large pieces that wait in a tray under the board. There are 17 pictures: a cat, a dog, a cow, a chicken, a lion, a tiger, a sheep, a deer, a dragon, a fish, a bird, a car, a train, a ship, a rocket, a castle, and a robot. The picture shows faintly on the board, and a piece dropped near its spot snaps into place. When the picture is done, the voice says its name. Puzzles grow from 4 pieces to 6, 9, 12, and 16.

Numbers: sudoku for kids with digits they already know. It starts on 4x4 boards and adds 6x6 boards as your child goes along.

Words: a word search on 8x8 and 10x10 grids, built from word lists for ages 5 to 8. Each word is read aloud when it's found.

READ ALOUD, WITH CHEERS
A voice says each digit as it's placed, each letter your child taps, and each word as it's found. It speaks English, Turkish, or German to match the app, and English in any other language. It also cheers your child on after every solved puzzle.

NO PRESSURE, NO LOCKS
Each game is a numbered path, shown 20 puzzles at a time. Every puzzle is open from day one, and the next unsolved one is highlighted. There's no timer, no lives, no score, and no leaderboard.

Each solve earns 1 to 3 stars, never taken away. Stars depend only on hints: no hints earn 3, 1 hint earns 2, and 2 or 3 hints earn 1. Every puzzle has 3 hints. Mistakes never cost a star; in sudoku, a wrong digit turns red until it's changed, and the voice gently says "Not quite."

A PARENT AREA BEHIND A PIN
The first time the app opens, a grown-up chooses a 4-digit parent PIN before your child plays. Tap the lock on Tinyfit's main screen and enter the PIN to open the parent area:
- how many puzzles your child solved this week, and their streak
- separate switches for read aloud and sound effects
- the app language
- a way to change the PIN
- the voice pack status, the privacy policy, and the version
- open source licenses and picture credits

Your child never sees a settings screen or a language menu.

NO ADS, NOTHING TO BUY
Tinyfit has no ads. There are no in-app purchases, no subscription, no account, no sign-in, and no chat. The jigsaw pictures are public domain (CC0) illustrations, each credited in the app with its source and license.

WORKS OFFLINE
The first launch needs the internet once to download puzzles, pictures, and voice clips. After that, Tinyfit plays offline. The one exception: when you switch the app language in the parent area, Tinyfit downloads that language's voice and words right away, so that one download needs the internet.

YOUR CHILD'S DATA
Stars, solved puzzles, and the PIN stay on the phone and are never sent to us. If Google backup is on, Android includes them in the phone's Google backup, as it does for most apps; the PIN is saved as a one-way code, never as the digits.

The app downloads its puzzles, pictures, and voice clips and checks for updates. To find and fix bugs, Tinyfit uses Google's Firebase Crashlytics. Each time the app is opened, or reopened after 30 minutes or more in the background, it sends a short session record (device maker and model, Android version, and network type) with an installation ID. If the app crashes or freezes, it also sends a crash report: what went wrong in the code, the steps just before it, and the phone's memory use at the time. Google keeps this data for 90 days and then deletes it; we keep none of it on our own servers. Tinyfit never asks for the camera, microphone, location, contacts, or photos. It shows no ads and uses no advertising ID.
