NumChop — Privacy Policy

Effective date: July 21, 2026

NumChop ("the App") is a math-practice game for children published by RT Vishnubhotla Creations ("we", "us"). This policy explains what information the App handles and how, in plain language for parents and guardians.

Our approach: no accounts, no personal information

NumChop does not require or ask for a name, email address, birthdate, photo, or any other personal information. There is no sign-up, login, or user profile of any kind. A child can play immediately after installing the app.

Information stored on the device

The App saves the following data only on the player's own device, using standard local app storage. This information is never transmitted to us and we never see it:

• Coins earned and spent in the shop
• High score and best streak
• Selected blade trail, background theme, and school class/grade level
• Sound on/off preference

Uninstalling the App deletes all of this data. We have no ability to access, recover, or delete it on your behalf because it never leaves the device.

Advertising

NumChop shows optional rewarded video ads (powered by Google AdMob) only when a player chooses to watch one in exchange for an extra life — ads are never shown automatically or during gameplay. Because NumChop is directed at children:

• Every ad request is tagged as child-directed under COPPA, which instructs Google to disable ad personalization and interest-based targeting for our app.
• Ad content is restricted to Google's "G" (General Audiences) content rating.
• Before any ad is shown, a short "Ask a Grown-Up" screen requires an adult to solve a simple challenge, so a child cannot trigger an ad on their own.

Serving an ad requires Google's ad SDK to process technical identifiers (such as a non-personalized advertising or device identifier) on the device in order to select and display the ad and measure basic performance. We do not receive or store this information ourselves — it is handled by Google under its own privacy policy. You can read how Google Mobile Ads / AdMob handles data here: policies.google.com/technologies/ads and google.com/policies/privacy/partners.

What we don't do

• We don't collect names, emails, addresses, or contact lists.
• We don't use analytics or crash-reporting services.
• We don't allow in-app chat, comments, or any way for a child to contact another person through the App.
• We don't sell data — we don't have any user data to sell.

Children's privacy

NumChop is designed for children and is intended to comply with the Children's Online Privacy Protection Act (COPPA) and Google Play Families Policy requirements. Because the App collects no personal information and gates ads behind a parental gate with child-directed ad settings, no verifiable parental consent flow is required for the information described above. If you have concerns about your child's use of the App, please contact us using the details below.

Changes to this policy

If this policy changes, the updated version will be posted at this same page with a new effective date.
