Privacy Policy

Last updated: November 9, 2026

Momo's Coloring Club (the "Service") is run by Penggwin LLC ("we", "us"). This policy explains what information we collect, how we use it, and the choices parents have. We built the Service for families, so we collect as little as we can.

The short version

Only adults (18+) can create accounts. Kids use profiles that a parent creates, with no email or password.
We don't show third-party ads, sell personal information, or use tracking or analytics tools.
Payments go through Stripe. We never see or store full card numbers.
Parents can delete a child's profile, saved pages or the whole account at any time from the grown-up area.

Information we collect

From parents (account holders)

Account details: your name, email address and password. Passwords are handled by our sign-in provider (Google Firebase Authentication), and we can't see them.
Grown-up lock settings: whether a PIN is required and a scrambled (hashed) version of the PIN. We don't store the PIN itself.
Subscription details: your plan, its status, renewal or trial dates, and a customer ID from Stripe. Stripe collects your payment card and billing details directly.
Messages you send us, for example a support or privacy request.

About children (entered by a parent)

Child profiles: a first name or nickname and a profile color. We suggest using a nickname.
Activity inside the Service: favorite pictures and, with Plus, the colored pages a child saves to My Gallery, along with the date saved.

We don't ask children for their email address, phone number, photo, location, or any other contact information. Children can't chat with or message anyone through the Service, and nothing they make is shown publicly.

Collected automatically

Technical information: like any website, our hosting and server providers receive your IP address, browser and device type, and the time of requests. We use this only to run, secure and fix the Service.
Storage on your device: the site stores a few small settings in your browser, such as which child last colored and how long the grown-up area stays unlocked. For offline use, it also keeps the app, library pictures and your family's profile information on the device, and holds pages saved without internet until they upload. You can remove the pictures in Grown-ups → Account → Offline coloring. None of this is used for advertising or tracking.

How we use information

To provide the Service: sign-in, kid profiles, favorites, My Gallery, downloads and printing.
To process subscriptions, free trials, renewals, refunds and cancellations.
To send account and billing messages, such as receipts, trial reminders and renewal reminders.
To keep the Service safe, prevent abuse, and fix problems.
To comply with the law.

We don't use children's information for advertising, and we don't build profiles of children for marketing. The only promotions in the free version are our own messages about Plus.

Who we share information with

We don't sell or rent personal information. We share it only with service providers that help us run the Service, under contracts that limit how they can use it:

Google (Firebase and Google Cloud): hosting, sign-in, database, file storage and server functions. Data is stored in the United States.
Stripe: payment processing and subscription billing. See Stripe's privacy policy at stripe.com/privacy.
Google Cloud Vertex AI (Gemini): creates AI drawings from the picture ideas kids type (see "AI drawings" below).
Google Fonts: provides the site's typefaces and receives your IP address when fonts load.

We may also share information if required by law, to protect the safety of a child or anyone else, or as part of a sale or transfer of the business. In a sale or transfer, this policy would continue to protect the information.

Children's privacy (COPPA)

The Service is intended for children to use with a parent's involvement. Under the U.S. Children's Online Privacy Protection Act (COPPA):

Only a parent or guardian 18 or older can create an account. The parent sets up each child's profile.
We collect only the child information listed above, and only to provide the Service.
A parent can review a child's information and saved pages in the Service at any time, change a profile name, and delete a profile, saved pages or the entire account.
A parent can ask us to stop collecting a child's information. The simplest way is to delete the child's profile, which removes the profile, favorites and saved pages.
You can also contact us at the address below to review or delete your child's information.

If you believe a child has created an account without a parent, please contact us and we will delete it.

How long we keep information

Account, profile and gallery information is kept until you delete it or delete your account.
When you delete your account, we delete your login, kid profiles, favorites and saved pages, and cancel any subscription.
Stripe keeps payment and transaction records as required by tax and financial laws. Server logs and backups may keep limited information for a short time before they are deleted.

Your choices and rights

Access and correct: view and change your name and kid profiles in the grown-up area.
Delete: delete saved pages, kid profiles or your whole account under Grown-ups → Account → Delete account.
Billing: update your card, see receipts or cancel under Grown-ups → Account.
Requests: email us to request a copy of your information or to exercise any other privacy right you have under the law where you live, including Colorado. We'll respond within the time the law requires, and we won't treat you differently for making a request.

Security

We use encrypted connections (HTTPS), access rules that keep each family's data separate, and trusted providers for sign-in and payments. No system is perfectly secure, so please use a strong, unique password and keep it private.

AI drawings

Kids can describe a picture (for example, "a turtle having a birthday party") and the Service creates a coloring page from it.

What's sent: only the picture idea, wrapped in our kid-safe drawing instructions, is sent to Google's Gemini image model through Google Cloud (Vertex AI) to make the drawing. No name, email or account details are sent with it.
Safety checks: before anything is sent, we check ideas and block famous characters, brands, personal information such as emails, links and phone numbers, and topics that aren't right for kids. Google's safety filters also apply.
What we keep: the idea text and the finished drawing are saved in your family's account so your child can color it later. They're private to your family and never shown publicly. Delete them anytime from the Create tab, or by deleting the child's profile or your account.
Training: under Google Cloud's terms for this service, Google doesn't use this data to train its AI models.
Counting: we keep a monthly count of drawings made by each family and each child per day, to apply plan limits.

Please remind kids not to type real names or other personal details into their ideas.

Club Highlights (sharing with other families)

Only a grown-up can share. Sharing a saved page needs the grown-up check, and a confirmation explains what other families will see.
What other families see: the colored page, the picture's name, the date, and the first letter of the child's profile name. Never the full name, your account details or anything else.
Who sees it: only signed-in Club families, after one of our team reviews and approves the page. Shared pages are never public on the web or on social media.
Removing: remove a shared page anytime in Grown-ups → Kids. Deleting a child's profile or your account removes everything that profile or account shared.

Guests

Visitors can color a few pictures without an account. We don't collect any personal information from guests, and nothing a guest colors is saved by us.

New features

Before any new feature collects or shares information in a new way, we'll update this policy and, where the law requires, ask for a parent's consent.

Changes to this policy

We'll post any changes here and update the date at the top. If a change is significant, we'll notify account holders by email or in the Service before it takes effect.
