Privacy Policy

Last updated July 19, 2026

Overview

This Privacy Policy explains how Wonderline collects, uses, discloses, retains, and protects information when you use Wonderline, including the Wonderline mobile apps, websites, subscriptions, support workflows, SMS features, and family profile tools.

Because Wonderline is used by families, we try to limit data collection to what we need to operate the product, support households, process subscriptions, manage messaging, improve reliability, prevent abuse, and comply with law.

Categories of personal information we collect

We collect identifiers and account data such as name, email address, authentication-provider identifiers, user ID, subscription identifiers, billing-related customer IDs, phone numbers, and support communications.

We collect family-profile information you choose to provide, such as child names, profile details, household configuration, the adults you add to your account, and other content you submit to personalize the service.

We collect content and activity data such as prompts, chat messages, AI interaction history, SMS consent records, records of the people you add and their invitations, message metadata, feature usage, and account settings. This can include child-related or household information that a parent, guardian, or authorized user includes in free-text submissions even if that information was not entered into a dedicated profile field.

We collect internet, device, and technical data such as IP address, device identifiers, browser type, app version, crash or diagnostic information, and basic service logs needed to secure, operate, and troubleshoot the product.

On our website, we collect advertising and measurement identifiers, such as the cookie identifiers set by the Meta pixel, so we can measure whether our advertising is working. See "Advertising and measurement" below.

If you enable notifications, we collect a device push token (for example, an Expo push token) so we can deliver reminders and character message notifications to your device. You can turn notifications off in your device or app settings.

Sources of information

We collect information directly from you when you create an account, purchase a subscription, create family profiles, contact support, enable SMS, connect sign-in providers, or otherwise use Wonderline.

That direct collection can include information you type into chats, prompts, support messages, onboarding questions, SMS and account-sharing setup flows, and other open-text inputs. As a result, information about a child or household member may come from what a parent or guardian voluntarily writes in Wonderline, not only from structured profile forms.

We also receive information from third parties that support the service, such as authentication providers, app stores, payment processors, cloud providers, messaging vendors, error-monitoring and diagnostics tools, and other service providers acting on our behalf.

How we use information

We use personal information to provide and maintain Wonderline, personalize family experiences, authenticate users, process billing, manage subscriptions, enable SMS texting and account sharing, respond to support requests, and communicate service-related updates.

We also use information to improve reliability and product quality, monitor performance, investigate fraud or abuse, moderate safety risks, enforce our terms, comply with legal obligations, and protect Wonderline, our users, and the public.

Children and COPPA-related information

Wonderline is a tool for parents and other adults. It is not directed to children under 13, and accounts may only be created by adults 18 or older. Children do not use the app.

Wonderline parent accounts may provide information relating to children in their household. We expect parents or legal guardians to submit only the information reasonably necessary for the intended family experience.

Child-related information associated with a Wonderline account may be provided directly in profile fields or may be inferred from what a parent or guardian enters into chats, prompts, support communications, onboarding responses, or other interactions with Wonderline.

If Wonderline is subject to the Children's Online Privacy Protection Act for a particular use case, the parent or guardian account holder is the person authorized to provide consent, review the child-related information associated with the household account, request deletion, and withdraw consent for further collection where applicable.

If you believe we collected child-related information without proper authorization, contact us immediately at info@wonderlineapp.com so we can investigate and take appropriate action.

AI and service providers

To operate Wonderline, we may send account, chat, and family-context data to service providers that help us provide authentication, hosting, cloud functions, database storage, subscriptions, payment processing, SMS delivery, customer support, AI response generation, and error monitoring.

Representative providers we currently rely on include Google Firebase and Google Cloud (authentication, hosting, database, and cloud functions), OpenAI (AI response generation and content moderation), Twilio (SMS delivery), RevenueCat together with the Apple App Store and Google Play (mobile subscriptions), Stripe (web billing), Sentry (error monitoring and diagnostics), Cloudflare (website traffic measurement and email routing), and Meta (website advertising measurement, as described under "Advertising and measurement"). These providers act on our behalf and may change over time as the service evolves.

That means prompts, messages, and related family-context information may be processed by third-party providers acting on our behalf so the service can function. We do not intend to use optional analytics or model-improvement settings beyond what is needed to operate the service unless and until we update our practices and provide any required notices or choices.

How we disclose information

When you add another adult to your account, we make your family's information available to them inside Wonderline — including your child profiles, your conversations with the characters, Nice Meter history, and family memories. That disclosure happens because you chose to add them, it lasts until you remove them, and you can remove them at any time from the People screen.

We disclose information to vendors and service providers that process information on our behalf for hosting, infrastructure, authentication, database storage, billing, messaging, customer support, and similar operational needs.

We may disclose information when required by law, to respond to lawful requests, to protect rights and safety, to investigate fraud or abuse, to enforce our agreements, or in connection with a merger, financing, acquisition, bankruptcy, or sale of some or all of our assets.

If California privacy law applies to your use of Wonderline, we do not sell personal information for money. The advertising measurement described under "Advertising and measurement" may qualify as "sharing" personal information for cross-context behavioral advertising under California law. You can opt out of that sharing from the "Do Not Sell or Share My Personal Information" page linked in our website footer, by sending a Global Privacy Control signal, or by contacting us at info@wonderlineapp.com.

Advertising and measurement

We advertise Wonderline on third-party platforms, including Meta (Facebook and Instagram). To understand which advertising works, our website uses the Meta pixel, which sets a cookie in your browser (for example, one named _fbp) and reports events such as viewing a page, creating an account, and starting a subscription.

We also send a limited set of these events to Meta directly from our servers using Meta's Conversions API. For a completed purchase, that transmission includes a one-way cryptographic hash of your email address, your IP address, your browser's user-agent string, Meta's advertising cookie identifiers if present, and the purchase amount and currency. We hash the email address before it leaves our systems: we do not send Meta your plain-text email address, your name, your children's names or profile details, or the contents of any chat, prompt, or message.

Meta uses this information to attribute purchases to advertising, to measure and improve ad delivery, and for its own purposes in accordance with its terms and policies. You can review how Meta handles this information in Meta's own privacy policy and Business Tools terms.

This advertising measurement applies to our website. Our mobile apps do not include advertising or attribution SDKs.

We switch advertising measurement off entirely for visitors in the European Economic Area, the United Kingdom, and Switzerland, so no advertising cookie is set and no request is made to Meta from those regions. We also honor the Global Privacy Control browser signal wherever it is sent.

You can opt out at any time from the "Do Not Sell or Share My Personal Information" page linked in our website footer, by contacting us at info@wonderlineapp.com, by using browser or device controls that block advertising cookies, or through the ad preference controls Meta provides. Opting out does not affect your account or your ability to use Wonderline.

SMS and phone number disclosures

If you enable SMS texting, we collect phone numbers, consent and opt-out records, message metadata, which person a number belongs to, and related account information needed to provide and secure those features. When you add someone else's phone number, you confirm you have their permission to do so; we record that confirmation, and that number must also reply to confirm before we text it again.

You or the phone-number owner can opt out of future texts by replying STOP where applicable. We may send a one-time, non-marketing confirmation of an opt-out request where permitted by law.

Retention

We retain information for as long as needed to provide the service, maintain family accounts, support subscriptions, secure the platform, resolve disputes, enforce agreements, and comply with tax, payment, accounting, audit, and legal obligations.

Retention periods vary by data type. For example, account records, billing records, logs, consent records, and support communications may be kept for different periods depending on operational and legal requirements.

Your privacy choices and rights

You can update some account information in the app, request deletion through the in-app delete-account flow, or contact us at info@wonderlineapp.com for privacy-related requests.

Depending on where you live, you may have rights to request access to, correction of, deletion of, or a copy of certain personal information, and to appeal a denied request where applicable. We may need to verify your identity before completing certain requests.

We will not discriminate against you for exercising applicable privacy rights, although some services may no longer function if necessary information is deleted.

California privacy disclosures

If the California Consumer Privacy Act or similar state law applies to your use of Wonderline, the sections above describe the categories of personal information we collect, the sources of that information, the business or commercial purposes for which we use it, and the categories of third parties to whom we disclose it.

Authorized agents may make requests on behalf of California residents where permitted by law, subject to verification and proof of authority.

Cookies, local storage, and similar technologies

Wonderline uses browser storage and similar technologies for two purposes: to operate and secure the service, and — on our website only — to measure the effectiveness of our advertising. We do not use these technologies to build profiles of children.

On the web, we use strictly necessary storage to keep you signed in (for example, browser local storage used by our authentication provider) and security technologies that protect the service from abuse and fraud, including Google reCAPTCHA and Firebase App Check, which may set a cookie or read device signals for that purpose. We also use Sentry to capture error and diagnostic information, which can include technical data such as an IP address, so we can detect and fix problems.

We use Cloudflare Web Analytics to count visits and see which pages people reach. It is cookieless: it sets no cookie, stores nothing on your device, does not track you across other websites, and reports only aggregate traffic information.

Our website also uses advertising and measurement cookies set by the Meta pixel, described under "Advertising and measurement" below. Unlike the technologies above, these are not strictly necessary to operate Wonderline.

Security

We use reasonable administrative, technical, and organizational safeguards designed to protect information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

International data transfers

Wonderline is operated in the United States, and we and our service providers may process information in the United States and other countries whose data-protection laws may differ from those where you live.

Where we transfer personal information from the European Economic Area, the United Kingdom, or Switzerland to a country that has not received an adequacy decision, we rely on appropriate safeguards for that transfer, such as the European Commission's Standard Contractual Clauses and the UK International Data Transfer Addendum, and, where applicable, on our providers' certification under the EU-U.S. Data Privacy Framework and its UK extension. Our key providers, including Google, OpenAI, and Stripe, offer these mechanisms. You may contact us at info@wonderlineapp.com for more information about the safeguards we use.

European Economic Area, United Kingdom, and Switzerland

If you are located in the European Economic Area, the United Kingdom, or Switzerland, this section applies to you and supplements the rest of this policy. For the processing it describes, the data controller is WonderNook Studios LLC.

We process personal information on the following legal bases: to perform our contract with you and provide the service you request (such as running your account, generating character responses, processing subscriptions, and delivering messages you enable); for our legitimate interests (such as securing the service, preventing fraud and abuse, improving reliability, and diagnosing errors), balanced against your rights and freedoms; to comply with legal obligations (such as tax, accounting, and responding to lawful requests); and, where we ask for it, with your consent, which you may withdraw at any time without affecting processing that already took place.

Subject to the conditions and exceptions in applicable law, you have the right to request access to your personal information; to correct inaccurate information; to erase your information; to restrict or object to certain processing, including processing based on our legitimate interests; to receive a portable copy of information you provided; and, where processing is based on consent, to withdraw that consent. Exercising these rights will not lead to discriminatory treatment, though some features may stop working if information needed to provide them is deleted.

To exercise these rights, use the in-app controls or contact us at info@wonderlineapp.com; we may need to verify your identity first. You also have the right to lodge a complaint with your local data protection authority (in the United Kingdom, the Information Commissioner's Office), though we would welcome the chance to address your concern first.

Changes to this policy

We may update this Privacy Policy from time to time. If we make material changes, we may notify you through the app, website, email, or another reasonable method and update the Last Updated date shown above.
