Privacy Policy

Last updated: November 2, 2026

This is how MINDO KIDS handles information about your child and about you, in plain English. It is also our notice to parents under the Children's Online Privacy Protection Act (COPPA).

1. Who we are

MINDO KIDS is a homework app for kids in grades 2–7. It helps them sit down and start: it breaks homework into small steps, runs a timer with breaks, and lets them raise an owl named Gus. The app is at app.kids.mindo.club and the website is at kids.mindo.club.

MINDO KIDS is operated by Rivka Erlanger, a sole proprietor registered in Israel ("MINDO KIDS," "we," "us"). Rivka is the only operator that collects or keeps information through MINDO KIDS. You can reach us at:

• Email: privacy@mindo.club
• Mail: Rivka Erlanger (MINDO KIDS), 34 Sderot HaEmoraim, Beit Shemesh 9920479, Israel
• Phone: +972-52-716-1835

2. Children and parental consent

MINDO KIDS is made for children, so we treat everyone who uses the kid side of the app as a child, whatever their age. A 13-year-old gets the same protections as a 7-year-old.

Everything starts on your device

When your family starts using MINDO KIDS, your child's nickname, homework, stars and Gus are saved only in the browser on that device. Nothing your child types leaves the device. The only thing the app sends is the anonymous usage counts described in section 5, which COPPA allows without consent.

Cloud save needs your consent

Cloud save keeps your child's progress safe if you change phones, clear the browser, or want a second parent to see it. To turn it on, a parent goes to the Parent Zone and enters their email address. Then:

• We email you a notice that explains what will be saved and asks for your consent.
• You confirm in that email. Only then does anything about your child leave the device.
• About a day later we send a second email confirming your consent, with a link to withdraw it if it wasn't you or you change your mind.
• If you don't confirm within 14 days, we delete your email address and nothing about your child is uploaded.

You can agree to cloud save without agreeing to any sharing with third parties. We don't share your child's information with third parties at all (see section 7). We never ask a child for more information than the activity needs, and no feature depends on giving us more.

Kids can't post anything publicly in MINDO KIDS, and there is no chat, messaging or social feature. Kids never see prices or purchase buttons. Only a parent can subscribe, from the Parent Zone or our website.

3. What we collect

About your child (on the device; in the cloud only after your consent)

• Profile: a nickname, the grade, and, if you choose, how Gus should refer to them.
• Homework: the subject, pages or problem numbers, and an optional short description in the child's own words (for example, "write a paragraph").
• Tests: the date, the topics, and how the child felt it went afterward ("went well," "so-so," or "was hard"). Never grades or scores.
• Progress: stars, Gus's stage, Gus's outfits and furniture, mini-games played, and time spent on tasks.
• Settings you choose, such as shorter steps or the name of a reward.

Please don't type a last name, school, address, phone number or anyone else's private details into the nickname or homework boxes. They're meant for things like "math, page 42."

About you, the parent

• Your email address, when you turn on cloud save or sign in. If you sign in with Google, we also receive the name and profile photo on your Google account.
• Consent records: when we sent the notice, when and how you confirmed, which version of this policy you saw, and any withdrawal.
• Your email address from an ad form, if you ask for our link through a form in one of our ads on Facebook or Instagram. Meta runs that form and sends us your email address and which of our ads you used. The form never asks about your child.
• A gift code, if you enter one we gave you.
• Subscription details from Paddle, our payment reseller, if you subscribe: plan, status, renewal date, country, and Paddle's customer and subscription numbers. We never receive or store your card number (see section 12).
• What you write to us, if you email us.

Collected automatically

• The anonymous usage counts described in section 5.
• Page-view totals from Vercel Web Analytics on our website and app. It uses no cookies. Vercel says it recognizes a visit by a hash of the request that is discarded after 24 hours, and we see only totals.
• IP addresses and similar technical data in our providers' server logs, which they need to deliver the service and keep it secure.

4. What we never collect

Last names, birthdays, photos, videos, voice recordings, school names, location, contacts, advertising IDs, or access to the microphone or camera. We don't collect health information or diagnoses. Your child's daily mood check-ins stay on the device and are never sent to us.

5. Anonymous usage counts (persistent identifier)

To see where kids get stuck and to make the app better, the app counts general actions: the app opened, a child profile was made, a task started or finished, a break was taken. The first time the app opens, it makes up a random number (like k3x9q2a7mf) and keeps it in the browser. Each count is sent with that random number and a few plain facts: the action's name, the grade number, timing (such as how many minutes a step took), and whether it's a phone or a computer.

We also record, in the same way: where the device first came from (a tag in one of our links, the name of the website that sent it, or a gift code), the browser and operating system type (for example, "Safari on iPhone"), and error messages when something breaks in the app. We clean error messages so they don't contain names, emails or anything a child typed.

What we use it for. Under COPPA, this random number is a "persistent identifier." We use it only to support the internal operations of MINDO KIDS: to count how many devices reach each step, to make time estimates realistic, to find and fix errors, to understand which of our links bring families in, and to keep the service secure.

How we make sure it's used for nothing else:

• It's random. It isn't built from anything about your child or your device.
• It's never sent together with your email, your child's nickname, anything your child typed, or your child's mood, and it isn't linked to your cloud save.
• The app can only add counts. It can't read them back. Only Rivka can see them, for the purposes above.
• We never use it to contact anyone, to show ads, to build a profile of a child, or to treat a particular child differently, and we never share it.

Clearing the browser's data deletes the random number, and the app makes a new one.

6. How we use information

• To run the app: save progress, sync it across your devices, and show your child's homework, stars and Gus.
• To give you the Parent Zone and the weekly report.
• To ask for and record your consent, and to honor your choices.
• To send you service emails: sign-in codes, consent notices, and important changes. We send marketing emails only if you ask for them, and every one has an unsubscribe link.
• To email you our link, tips for getting started, and news about MINDO KIDS, if you asked for them through a form in one of our ads.
• To manage your subscription and gift codes.
• To improve and fix the app, and to keep it secure.
• To meet legal duties.

We don't use your child's information for advertising, for marketing to your child, to build profiles, or to train artificial intelligence. There is no AI in MINDO KIDS. We don't look at your child's saved content unless you ask us for help and we need to check something to give it.

7. Who we share it with

We don't sell, rent or trade information about your child or you, and we don't share it for advertising. We don't disclose your child's information to third parties.

We use a few service providers that run parts of the service for us. Each is bound by its contract with us to use the information only to provide its service to us and to keep it secure:

Forms in our Facebook and Instagram ads. Some of our ads include a short form where a parent can ask us for the link to MINDO KIDS. Meta Platforms runs that form under its own privacy policy and passes us your email address and which ad you used. We use them only to email you the link, tips for getting started, and news about MINDO KIDS. Every one of these emails has an unsubscribe link. We send nothing back to Meta: not your email address, not whether you started, and nothing about your child. There is no Meta pixel or other Meta code on our English site (kids.mindo.club/en) or in the app.

We may also disclose information if the law requires it, to protect the safety of a child or others, or to protect the security of the service. If MINDO KIDS is ever transferred to a new owner, these promises go with it, and we'll tell you first and ask for new consent where the law requires it.

8. Your rights as a parent

At any time, you can:

• Review the information we have about your child.
• Get a copy of it in a file.
• Correct it.
• Delete it: one child or your whole account.
• Stop further collection. We turn off cloud save for your family, and your child can keep using the app on the device only.
• Withdraw your consent, which turns off cloud save and deletes your child's cloud copy.

How: In the app, the Parent Zone lets you see and change your child's information and remove a child, which deletes that child's progress from the cloud too. The link in our consent confirmation email withdraws consent. For anything else, or if you prefer, email privacy@mindo.club from the email address on the account, or call or write to us (section 1). We'll check that the request comes from the account holder and answer within 30 days, usually much sooner. Deleting a whole account is completed within 30 days.

We never charge for these requests, and we won't treat you differently for using them.

9. How long we keep it

We keep information only as long as we need it for the reason we collected it, and never indefinitely. This is our data retention policy:

What's saved only on your device stays there until you remove the child in the app or clear the browser's data.

10. Security

We follow a written information security program that fits a small service holding children's information. Information travels over encrypted connections (HTTPS) and is encrypted at rest by our database provider. Database rules let each family reach only its own information, the app's public key can't read anyone's saves, and administrator access is limited to Rivka. We review risks at least once a year and only use providers that commit in writing to protect the information.

No system is perfectly secure. If a security incident puts your information at risk, we'll notify you and the authorities as the law requires.

11. Cookies and device storage

We don't use tracking cookies, advertising pixels, or third-party analytics that follow you across websites. The app uses the browser's own storage to keep your child's progress, the random number for usage counts, and, if you signed in, your sign-in session. Our checkout page, which you reach only from the Parent Zone, loads Paddle's payment script. It uses its own cookies to take payment and prevent fraud. It also loads ProfitWell (now Paddle Retain), Paddle's own tool for its subscription services, such as recovering failed payments. Neither runs in the app your child uses. Because we don't track you across sites or sell information, there is nothing extra to opt out of; we still treat a browser's Global Privacy Control signal as an opt-out.

12. Payments

Subscriptions are sold by Paddle.com Inc., our reseller and merchant of record. Paddle collects your email, billing country, ZIP code and payment details at checkout, and handles payment, sales tax, receipts and refunds under Paddle's privacy notice. Paddle tells us your plan and subscription status so the app knows what's included. We never see or store your full card number. Paddle never receives information about your child.

13. State privacy rights

Depending on your state, you may have the right to know what we collect, to get a copy, to correct or delete it, and to opt out of the sale or sharing of personal information, targeted advertising and profiling. We give every parent these rights, whatever their state, the same way as in section 8. We don't sell or share personal information, including of anyone under 16, and we don't use your or your child's information for targeted advertising or profiling. If we turn down a request, you can appeal by replying to our answer, and if you're still not satisfied, you can contact your state attorney general. California residents: we don't share personal information with others for their direct marketing.

14. Where information is stored

MINDO KIDS is run from Israel. Cloud saves are stored in Frankfurt, Germany, and our providers may process information in the United States and other countries where they operate, under the protections described above.

15. Changes to this policy

If we make a material change, we'll update the date at the top and tell parents by email and in the app before it takes effect. If a change affects your child's information in a way you haven't agreed to, we'll ask for your consent first.

16. Contact us
