Spell Pong (“the app”) is made by SpellGamez. Contact: info.spellgamez@gmail.com. The app is a word game for adults learning vocabulary in English, Spanish or Portuguese.

Playing on your own

Your scores, settings (game mode, chosen word list and topic), daily challenge results and the words you have learned stay on your phone, unless you create a player profile (below). Uninstalling the app or clearing its data deletes them.

Player profile (optional)

To keep your progress on another phone, you can sign in with Google. We then store, in Google Firebase (Cloud Firestore, United States): the name of that Google account, and for each word list how many times you spelled each word. Only you can read it.

My words › Profile › Delete profile deletes it, together with your sign-in account and any shared lists you joined. The words kept on the phone stay.

Usage statistics (Google Analytics for Firebase)

To see where the game is too hard or too easy, the app sends usage events: a game started (level, mode, word list), a word finished (level, number of letters, mistakes, seconds), a level reached, a game paused or continued, a game over (score, words, time), a daily challenge or a practice finished, the share button used, and a list added. Google adds a random app-instance ID, device model, Android version, app version and country (from the IP address, which isn’t stored). These events never include names, email addresses, nicknames or anything you type. In the EEA, UK and Switzerland your choice in Google’s consent form applies to them too. Google’s policy: firebase.google.com/support/privacy

Online classes (optional)

Online classes use Google Firebase (Cloud Firestore, Authentication and Cloud Functions), with data stored in the United States.

Teachers sign in with their Google account. We store:

• the name and email address of that Google account, and the teacher name they type;
• their word lists (classes) and each class’s join code;
• whether they have an active Teacher plan.

Students join a class with a code and a nickname they choose. They don’t give an email or create a password: the app signs them in anonymously with a random ID. We store:

• the nickname and which classes they joined;
• the results of games played on a class’s word list: score, level, game mode, and for each word how many mistakes were made and how long it took.

Who sees it: a class’s teacher sees the nicknames and results of the students in that class. Students see their own results, not their classmates’. Nobody else, including other teachers, can read a class.

Deleting your data

• Players: My words › Profile › Delete profile.
• Teachers: Custom lists › Delete account deletes their classes (with all students’ results in them), their profile and their sign-in account.
• Students: My lists › Delete my shared-list data removes them from every class and deletes their results. Leaving one class removes them from it.
• Teachers can delete a class at any time; its results go with it.
• Without the app: see how to delete your account, or write to info.spellgamez@gmail.com.

Deleting an account doesn’t cancel a Teacher plan subscription: cancel it in Google Play › Payments & subscriptions.

Sharing by message

You can share a word list or a game’s results through your phone’s share menu (for example WhatsApp or email). You see the message before sending it and choose who receives it; that message doesn’t pass through our servers.

Advertising (Google AdMob)

The app shows optional rewarded ads and, at most once per session, a full-screen ad. Google AdMob may collect your device’s advertising ID, IP address and information about ad interactions to show and measure ads. In the EEA, UK and Switzerland we ask for your consent first (Google’s consent form); you can change your choice at any time with Privacy options at the bottom of the menu. Google’s policy: policies.google.com/technologies/ads

Crash reports and app integrity (Google Firebase)

If the app crashes, Firebase Crashlytics sends a crash report: device model, Android version, app version and technical details of the error, with a random installation ID. It doesn’t include names, word lists or results. Firebase App Check asks Google Play Integrity whether the app is a genuine copy, to keep the service free of abuse.

Purchases (Google Play)

The Teacher plan is a Google Play subscription. Payment is handled by Google; we never see card details. Our server asks Google Play whether a teacher’s subscription is active and links the purchase to their teacher account. Manage or cancel it in Google Play › Payments & subscriptions.

Children

Spell Pong is made for adults learning a language. It is not directed at children under 13 (or the minimum age in your country), and we don’t knowingly collect their data. Teachers: please use online classes only with adult learners. If we learn that a child’s data was collected, we delete it; tell us at info.spellgamez@gmail.com.

Security and retention

Data is sent encrypted (HTTPS) and protected by access rules: each person can only read what is theirs or their class’s. We keep online data until you delete it as described above; crash reports and usage statistics are kept by Google for the periods set in its policies.

Your rights

You can ask what data we hold about you, correct it, or have it deleted, at info.spellgamez@gmail.com. If you are in the EU you can also complain to your data protection authority.

Changes

We’ll update this page and the date above when the app changes how it handles data.
