At Gritty Kids LLC, we prioritize the privacy and well-being of children using our products and services, including our App. We implement multiple safeguards to protect children and only collect personal information when voluntarily provided by their parents or guardians. We ensure that parents have access to and control over the information they provide.
At Gritty Kids LLC (“Gritty Kids”, “we”, or “us”), we cherish the trust you place in us and are committed to creating a safe and enjoyable online environment for family members of all ages.
The App is owned and operated by One4Yes, LLC (“One4Yes”) under an official license from Gritty Kids. References in this policy to “we” or “us” in connection with the App therefore include One4Yes acting as the operator under that license. One4Yes handles the information practices described below on the same terms.
This privacy policy applies to our mobile application (the “App”), our website, and any other interactions you may have with us, covering our handling of personal information concerning identifiable individuals. This policy does not cover anonymous or business information.
The policy is applicable globally, with additional details provided for residents of the European Economic Area, the United Kingdom, Switzerland, and California.
By using our App, our website, or sharing information with us, you consent to the information handling practices described in this Privacy Policy.
We do not collect biometric or health data, nor personal information about your child through our App, unless you, as their parent or guardian, voluntarily provide it.
We collect limited usage information when you, as a parent, download and use the App. We generally do not require personal information about your child, and the App does not ask for any name, email address, age, photo, or other personal detail about you or your child in order to play.
When you subscribe for services through our App, Apple or Google may share information with us if you have consented to that sharing through your App Store or Google Play account. We may collect additional information if you contact our support team or otherwise communicate with us about the App.
If you enter your email address on our website to download a free printable or to hear about updates, we store that email address and nothing else about you. We use it to send you the printable and occasional Gritty Kids news. Our emails are delivered by Resend, an email service provider, which processes your address only to send them. We do not sell or share your email address. These forms are meant for parents and teachers, not children. To stop the emails or have your address deleted, reply to any of our emails or write to app@grittykids.com.
Subscription payments made inside the App are processed through the Apple App Store on iOS, Google Play on Android, and the Amazon Appstore on Fire devices. We do not collect or see your payment information. We only receive a unique anonymous Subscriber ID issued by the store, along with the receipt and entitlement information needed to grant access to subscription content.
Purchases made on our website are processed by RevenueCat’s web billing service using Stripe, with Stripe acting as the merchant of record. Stripe collects your email address, your payment card, and the billing details needed for the payment and for sales tax. We never see your card number. We receive your email address, your country, and the details of what you bought (the plan, the price, and the date), which we use to provide your subscription, to answer support requests, and to measure our advertising as described below.
If you buy a group licence for a school or homeschool program, we store the delivery email address and the program or school name you give us at checkout, so that we can send you your unlock codes and resend them if you ask. That is the only personal information we hold for these orders. We do not collect anything at all about the families you pass a code to: redeeming a code tells us only that an anonymous install claimed it, and never who they are. Payment is processed by Stripe and we do not see your card details. You can ask us to delete your email address at any time by writing to app@grittykids.com, and we remove it automatically two years after every code on the order has been used.
We use RevenueCat, a third-party subscription management service, to validate purchases and manage subscription entitlements inside the App. The RevenueCat software development kit (SDK) embedded in the App independently transmits the following to RevenueCat’s servers when you interact with subscriptions: an anonymous RevenueCat-issued user identifier, the App Store or Google Play purchase receipt for the transaction, your current subscription and entitlement status, the product identifier and price, your device model, operating system version, App version, language, and country. For purchases inside the App, RevenueCat does not receive your name, email, or payment card details. For purchases on our website, RevenueCat also receives the email address you enter at checkout, because it runs that checkout for us. RevenueCat never receives any information about your child. RevenueCat’s use of this information is governed by its own privacy policy.
The App does not collect device serial numbers, advertising identifiers (Apple’s IDFA, Google’s Advertising ID / AAID), the Android Build Serial, MAC address, IMEI, or any other persistent platform-issued hardware identifier.
To group anonymous analytics events from the same installation of the App, we generate a random universally unique identifier (a UUID, which we call the “install ID”) the first time the App launches and store it in the App’s local storage on the device. The install ID is not tied to your subscription, your Apple or Google account, your device, or any personal information. It is reset automatically when the App is uninstalled, and a new random ID is generated on reinstall.
We also record the operating system the App is running on (“ios” or “android”) so we can interpret usage trends. This is not a personal identifier.
The App sends anonymous gameplay events to our own servers (operated for us by One4Yes) so we can understand how the App is used and improve it. These events are not linked to any identifiable individual. The fields we record for each event are:
We do not collect anything about who the player is, what they look or sound like, where they are, what they type, or what is on their device. We do not use this information to advertise to you or your child, and we do not sell it.
The App can send occasional push notifications about the service, for example a reminder that a free trial is ending or a notice that a new puzzle pack has been added. The first time you open the App, the operating system will ask whether you want to allow notifications. You may decline, and you can change your choice at any time in your device’s Settings.
If you allow notifications, the App receives a push notification token from Apple or Google and sends that token, along with the anonymous install ID and platform described above, to our own servers (operated for us by One4Yes) so we can deliver notifications to the App. The token is an opaque identifier issued by Apple or Google. It is not a name, email, age, or any other personal information about you or your child. It is reset when the App is uninstalled or notifications are disabled, and we delete tokens that the push service reports as no longer valid.
We use push notifications only for service messages of the kind described above. We do not use them for marketing to children, and we do not share or sell push tokens.
We want to be explicit about what the App does not access or transmit. The App does not collect or transmit:
The App also does not include any third-party analytics, advertising, crash reporting, or attribution SDKs (such as Firebase, Sentry, Crashlytics, Amplitude, Mixpanel, Segment, PostHog, or Datadog).
We may collect personal information through your interactions with our website or our social media accounts, for example if you submit a contact form or send us a message. This information helps us communicate with you, provide information you have requested, and understand usage of our website for analytics and ordinary business operations.
None of what this section describes exists in the App, and none of it collects information from children.
Website analytics. We count page visits on our own servers. We do not use Google Analytics or any other third-party analytics service. Visits are grouped using a code that changes every day, so we cannot follow a visitor from one day to the next.
Campaign cookie. On our checkout pages we set a single first-party cookie that records which marketing campaign brought you to us (the campaign tags in the link you followed and the referring site), so we can tell which campaigns lead to purchases. It stores no personal information and is not shared with third parties.
Meta advertising pixel. On the pages where you can buy Gritty Kids (our App page, our advertising landing pages, and the page you see after buying), we use a Meta (Facebook) advertising pixel. It tells Meta when you view the page, look at our prices, start a checkout, or start a free trial, so we can tell whether an advertisement worked. It is not used on our home page, our policy pages, our support page, our book pages, or any of our other content pages.
Purchase reports to Meta. When you buy or start a free trial through our website, our server reports it to Meta using Meta’s Conversions API. The report includes:
It never includes anything about your child. Meta’s use of this information is governed by its own data policy.
Your choices. Visitors in the EU, EEA, and UK, and visitors whose location we cannot determine, are asked first. If you decline, the campaign cookie is not set, the Meta pixel is not loaded, and nothing identifying is sent with a purchase. Anyone, anywhere, can opt out of sharing with Meta on our Your privacy choices page, and we treat a browser that sends the Global Privacy Control signal as opted out. If you opt out, we may still tell Meta that a sale happened, with the amount and plan only.
We do not sell personal information for money, and we do not lease it. We may share information with affiliates and service providers that help us operate the business (including One4Yes as the operator of the App under license, our hosting and infrastructure providers, RevenueCat for subscription management as described above, Stripe for website payments, and Apple, Google, and Amazon for payment processing), for legal reasons, or in response to lawful requests from authorities.
We also share the website purchase details described above with Meta to measure our advertising. Under some US state privacy laws, including California’s, this counts as “sharing” personal information for cross-context behavioral advertising, and may be considered a “sale”. You can opt out at any time on our Your privacy choices page. We do not share or sell any information about children.
We collect and use your information with your consent, which you can withdraw at any time. You can stop all gameplay analytics by uninstalling the App, which deletes the anonymous install ID from your device.
You have control over the information you provide and can manage subscription settings at any time through the Subscriptions area of your Apple ID or Google account. You may also contact us at any time to ask what information we hold and to request changes or deletion.
Your information may be accessible to law enforcement authorities outside your jurisdiction.
We protect your information with stringent security measures and retain it only as long as necessary.
You can delete your data at any time by deleting the App from your device. This removes the anonymous install ID and any other locally stored data. For questions about data deletion, contact us at app@grittykids.com.
You may request access to and correction of any personal information we hold.
Depending on where you live, you may have the right to know what personal information we hold about you, to get a copy of it, to have it corrected or deleted, and to opt out of its sale or sharing for targeted advertising. Residents of the EU, EEA, UK, and Switzerland may also object to our processing and withdraw consent at any time. We rely on your consent for the Meta pixel and purchase reports in those regions.
To opt out of sharing, use our Your privacy choices page or turn on the Global Privacy Control signal in your browser. For any other request, write to app@grittykids.com. We will not treat you differently for using any of these rights.
For any questions or concerns about our privacy practices, please contact us. For app specific questions, contact app@grittykids.com. For all other inquiries, contact info@grittykids.com.
We may update this policy and will notify you of any changes that affect parental consent requirements.
