Privacy Policy — Kids Flashcards: 13 Languages (formerly Kiddie Flashcards)

Last updated: September 27, 2026

Which app and developer this policy covers

This privacy policy applies to the following Android application and its developer, as listed on Google Play:

• App name: listed on Google Play as "Kids Flashcards: 13 Languages", previously "Kids Flashcards: 9 Languages" and originally "Kiddie Flashcards". This policy covers the app under any of these names; the listing and package are unchanged.
• Package name / application ID: com.yzy.kidsflashcards
• Google Play listing: play.google.com/store/apps/details?id=com.yzy.kidsflashcards
• Developer name (Google Play developer account): yzyy, an individual developer based in Singapore
• Contact email: yzyapps99@gmail.com

Kids Flashcards: 13 Languages ("the app"), formerly named Kiddie Flashcards, teaches young children animals, plants, the alphabet, numbers, colours, shapes and the world around them, in up to 13 spoken languages, using picture flashcards, sounds, quizzes and short illustrated stories. This page explains what data the app handles and who it is shared with. The app is provided by yzyy, an individual developer based in Singapore ("we", "us").

Summary

• The app is made for children. Its declared target age groups on Google Play are 5 and under and 6–8, so it is subject to Google Play's Families policy and we design it accordingly.
• No account is needed. The app never asks a child or a parent for a name, email address, phone number, photo or any other personal detail. The only way we ever learn who you are is if a parent chooses to email us feedback (see below).
• The app requests no runtime or sensitive Android permissions — nothing that Android asks you to approve. It uses only normal permissions: network access (internet and network state) — used by Google Play billing, by the anonymous analytics and crash reporting described below, and by older copies of the app that still download pictures from Firebase Storage; the current version packages every picture, sound and story inside the app — and Google Play's billing permission, used for the one-time Pro unlock below. Google's libraries add a few more normal permissions: Firebase Analytics adds a wake lock (so a batch of usage counts can finish sending), the Google Play install referrer (which tells us the app came from Google Play) and the Privacy Sandbox attribution permission; the advertising ID permissions are removed and the advertising ID is not used. An Android support library also adds one private permission that only the app itself can hold.
• The app shows no ads. Google AdMob was removed completely in version 2.2.0. There is no advertising SDK left in the app, and no advertising identifier is collected.
• There is one optional purchase. A single, one-time "Pro" unlock opens the rest of the card catalogue. There is no subscription and no other charge. It is bought through Google Play's own billing sheet, behind a parental gate, and the app never sees or stores any payment details.
• The app sends anonymous usage counts and crash reports through Google Firebase so that it can be fixed and improved.
• We do not sell data, and we do not operate any servers of our own.

Children's privacy and the Families policy

Because the app is directed to children under 13, we take these positions and have configured the app to enforce them in code, not merely to promise them:

• We do not knowingly collect personal information from children. The app has no fields in which a child could enter personal information, no profile and no chat. Its one purchase sits behind a parental gate, so a child cannot reach the payment sheet unaided.
• There is no advertising of any kind. The app contains no ad SDK, shows no ads, and builds no advertising profile from a child's use of it. Versions up to 2.1.3 did show child-directed, non-personalised ads through Google AdMob; that was removed entirely in version 2.2.0.
• The analytics SDK is prevented from collecting the advertising identifier and from sending ad-personalisation signals (google_analytics_adid_collection_enabled=false and google_analytics_default_allow_ad_personalization_signals=false).
• We aim to comply with applicable children's privacy laws, including the US Children's Online Privacy Protection Act (COPPA) and, for children in the EU/EEA and UK, the General Data Protection Regulation (GDPR).

If you are a parent or guardian and believe the app has collected information about your child that you would like removed, email yzyapps99@gmail.com and we will act on it — see Your choices and how to reach us below.

What data the app handles

The app itself asks for nothing about you. The data below is collected automatically by the Google services listed in the next section, and matches the Data safety declaration on the app's Google Play listing:

• Crash logs — if the app crashes, a report containing the device model, Android version and a diagnostic stack trace is sent so the defect can be found and fixed.
• Diagnostics — basic performance and error information of the same kind.
• App interactions — anonymous, aggregated counts of which screens, card categories and features are used, so that the app can be improved. These are tied to a random installation identifier, not to a person.
• Device or other identifiers — a random, app-specific installation identifier (the Firebase installation ID and the analytics app instance ID) that lets the services below tell one installation from another, so a crash report and the usage counts around it belong together. It is not the device's advertising identifier — the app does not collect that one — and it is discarded when the app is uninstalled.
• Purchase history — if a parent buys the one-time Pro unlock, the app records that the purchase completed, as one more anonymous usage event of the kind above. It is the bare fact that a purchase happened: no card details, no name, no receipt and no amount ever reach us, because Google Play handles the payment itself.
• IP address — like any internet request, the analytics, crash-reporting and billing calls described above carry the device's IP address to the Google service being contacted (as do the picture downloads that older copies of the app still make). An IP address can indicate approximate location such as a country or city; the app never requests, reads or transmits the device's GPS location, and holds no location permission at all.

None of this includes a child's name, voice, photographs or any content created in the app, because the app collects none of those things.

Third-party services used by the app

The app includes the following Google services, which collect data independently of us and under their own terms. Google's handling of that data is described in Google's privacy policy at policies.google.com/privacy.

• Google Play Billing — handles the one-time Pro unlock. The payment happens inside Google Play under Google's own terms; the app is told only whether the purchase succeeded, and never receives or stores payment details.
• Google Analytics for Firebase — records the anonymous usage events described above, with advertising-identifier collection and ad-personalisation signals switched off.
• Firebase Crashlytics — records crash and error reports.
• Firebase Storage — no longer used by the current version. Every picture, sound and story is packaged inside the app as of version 2.2.1, so the app makes no file-download requests and the Storage SDK is not present in it. Older copies still installed on a device continue to download pictures and audio from Storage until they update; those are ordinary file downloads that carry the device's IP address to Google, and no information about the child is uploaded either way.
• Google Play In-App Review — no longer used by the current version. As of version 3.0.0 the app never shows Google Play's in-app review prompt and never calls that service. Rating the app is now an option in the parent area, behind a parental gate, that simply opens the app's Google Play page; any review you choose to write there is handled by Google Play, not by the app.

We can see the reports these services produce in Google's own dashboards, in aggregate form. We do not receive, store or have any way to look up an individual child's data, and we do not combine this information with anything else.

What the app does not do

• It does not sell or rent data to anyone.
• It does not show ads of any kind, personalised or otherwise.
• It does not ask for or hold location, microphone, camera, contacts, storage or photo permissions.
• It has no login, no user profile, no chat and no user-generated content. The "share" button only passes a short message and a link to the app to Android's own share sheet, where you choose what to do with it; nothing about your use of the app is included and nothing is sent to us.
• It has no subscriptions and no recurring charges. The only way to spend money in the app is the single one-time Pro unlock described above.

If you email us feedback

The app has a feedback option intended for parents. It does not send anything by itself: it opens your own email app with a message already addressed to yzyapps99@gmail.com, and nothing reaches us unless you decide to send it. If you do send it, we receive your email address and whatever you write. We use that only to reply to you and to fix what you reported, we do not add you to any mailing list, and we delete the correspondence once it is no longer needed. Please don't include personal details about your child in it — we don't need any to help you.

Data retention

The crash reports and anonymous usage events are held by Google under Firebase's own retention settings and are deleted according to them. We keep no separate copy of any of it, and we have no database of our own. Uninstalling the app stops all further collection.

Your choices and how to reach us

• The app does not use the device's advertising identifier at all, so there is nothing to reset for it. The anonymous installation identifier described above is discarded when you uninstall the app.
• Uninstalling the app ends any further data collection by it.
• Parents and guardians may email us to ask what has been collected about their child, or to ask us to delete it. Because the data described above is not tied to a name or an account, please tell us the approximate date and the device model so we can ask Google to locate and delete the matching records. We will reply within 30 days.

Changes to this policy

We may update this policy from time to time. Any new version will be posted on this page with an updated "Last updated" date. If a change materially affects children's data, we will make the change before or at the same time as the app update that causes it.
