Terms of Use

Last updated: November 5, 2026

Browser version

The browser game (timestables.inudev.org) is free, needs no account and has no round limit. That will not change: the web version stays free.

Mobile apps

The Android and iOS apps are free to download and include 5 free rounds per day. An optional “Bubble Math Premium” subscription unlocks unlimited play. The free round counter resets every day.

Subscription and payments

Weekly and yearly subscriptions are available. Prices in your local currency are shown in the store before you buy. Payment is charged by Google Play or the App Store when you confirm the purchase. The subscription renews automatically for the next period until you cancel it in your store settings, at least 24 hours before the end of the current period. Cancelling does not refund a period already started. Only a parent or guardian may confirm a purchase.

Refunds

Refunds are handled by the store where you bought (Google Play or the App Store) under its rules. You can also write to us and we will help with the request.

Restoring purchases

An active subscription can be restored on a new device with “Restore purchases” on the subscription screen, using the same store account.

Acceptable use

The game is meant for children learning the times tables under the care of a parent or teacher. Do not copy, distribute or resell the app or its content, or bypass the limit or payment mechanisms.

Liability

We work to keep the game running well, but provide it “as is”. Game progress is stored only on the device and can be lost if app data is cleared. Nothing here limits consumer rights you have by law.

Changes

We may change these terms and the subscription price; a new price only applies after you agree to it in the store. The current version is always on this page.
