We do not collect or transmit any personal information.
Everything you do in our apps — your progress, your settings, your saved data — stays on your device.
There are no accounts, no sign-in, no analytics, no advertising and no tracking of any kind.
The only exception is a purchase. In apps that offer one, purchase information is sent to Apple and to our purchase-management provider so that your purchase can be restored. Nothing that identifies you personally is sent.
This policy applies to all apps published by Kanishi Studio, including:
First Move Maths
初手 (Shote) series — Maths, Physics, Chemistry, Arithmetic, Numerical Reasoning
Nothing. We do not collect your name, email address, location, contacts, photos, device identifiers or any other personal information.
The data our apps create — your learning records or game progress, your answer history, your bookmarks and your settings — is stored only on your device, and is never sent anywhere.
Your data is not shared with anyone, because it never leaves your device. We use no analytics service, embed no advertising SDK, and carry out no behavioural tracking or profiling. Our apps work fully offline.
The one exception is purchases. In apps that offer a purchase, we use RevenueCat together with Apple to complete the purchase, to restore it if you reinstall or change device, and to check whether it is active. What is sent is limited to which product was purchased, whether a purchase exists, and an anonymous identifier generated automatically for that purpose. No name, email address or other personally identifying information is sent, and none of it is used for advertising or tracking. RevenueCat's handling of that information is governed by its own privacy policy.
Export. Where an app offers it, you can save your data as a file on your device from the settings screen.
Deletion. "Reset data" in the settings screen erases everything the app has stored. Deleting the app does the same.
Because your data lives only on your device, moving to a new device means carrying your exported file across.
Where an app offers a purchase, it is a one-time purchase made through the App Store. Payment and billing are handled by Apple under Apple's own privacy policy. Our apps keep only an "unlocked or not" flag on your device and never receive your payment details.
Our apps are written for a general audience, including school-age students. Because we collect no personal information from anyone, no additional information is obtained regardless of age. Purchases go through the App Store's parental approval and Family Sharing mechanisms.
We may revise this policy from time to time. Significant changes will be noted in the store description of the apps concerned.
