Privacy Policy

The short version

• No accounts, no sign-in, no ads, no chat, no tracking, no links out of the app.
• Player names and all progress stay on your device, with a backup copy in your own iCloud if you are signed in.
• The app sends anonymous play statistics (counts only, with no identifier of the player, the device or the install) to our own server.
• When online, the app downloads extra levels and word banks from our own server.
• Purchases are handled entirely by Apple.
• No third-party analytics, advertising or crash-reporting software is in the app.

What stays on your device

The names the family types for each player, the chosen heroes, settings, progress, stars, coins, cards, and the answers given (used to choose the next questions and to show progress) are stored only in the app's own storage on the device. They are never sent to us or anyone else. Deleting a player in the app removes that player. Backups of your device made by Apple (iCloud or computer backups) may include this data under Apple's own terms.

iCloud backup

If you are signed in to iCloud, Mathaloria keeps a copy of its saved game (the players' names, their progress, answers and settings) in your own iCloud account using Apple's iCloud key-value storage, so progress survives reinstalling the app, a new device, or playing on both an iPhone and an iPad. Apple stores it in your iCloud under Apple's privacy policy; we have no access to it and it is not sent to us. Purchases are not part of it. If you are not signed in to iCloud, or turn iCloud off for Mathaloria, the game is saved on the device only, and deleting the app removes it.

Anonymous play statistics

To learn which levels are too hard, which topics are played and whether the game works well, the app sends small batches of play statistics over an encrypted connection (HTTPS) to our own server at content.mathaloria.com. Every record is from a fixed list, and every field is either a choice from the game's own lists or a number, for example: which Realm and level was played, the chosen topic, class and difficulty, won or lost, how long it took, how many answers were right or wrong (as counts), and how many errors the app ran into. Each batch also says the app's build number, the major iOS version (for example 18), whether it is a phone or a tablet, and the local day and hour of play.

The statistics never contain a name, anything typed, a question, an answer, a word asked, a location, an advertising identifier, a device identifier or model, or any identifier of the install. The only id is a random number made each time the app starts and thrown away when it closes. We cannot tell which device or child a record came from, so there is nothing we could link to a person, and nothing we could delete on request.

Retention: raw records are kept for at most one year (365 days), then only daily totals are kept. The data is never sold, shared or combined with other data, and never used for advertising.

Downloaded content

When the device is online, the app checks our server for new content packs (extra levels, word banks, seasonal events) and downloads small ones in the background. Packs are data and pictures only, never code. The request contains only the app's channel, platform and build number. Files are served from our server and its storage provider (Vercel Blob).

Our server and IP addresses

Like every server on the internet, ours sees the IP address a request comes from. We use it only in passing, to protect the server from floods of requests; we do not store it with the statistics. Our hosting provider (Vercel) keeps short-lived request logs under its own policy, and the statistics wait for us in a database at its storage partner (Upstash) until we collect them.

Purchases

The one in-app purchase (“Unlock the Full Adventure”) is made through Apple's App Store with StoreKit. Apple handles payment and your Apple account; we never see your payment details or your Apple ID. The app keeps only a note on the device that the unlock was verified.

Speech

Words are spoken by your device's own text-to-speech voice, on the device. The app never uses the microphone or the camera.

Children

Mathaloria is made for children and their families. We do not knowingly collect personal information from anyone, of any age. The anonymous statistics above contain no personal information. If you believe something personal reached us, write to us and we will look into it and delete it.

This website

mathaloria.com sets no cookies and uses no analytics, trackers or third-party scripts, and it asks for nothing about you. If you joined the beta before the launch, we keep the email you gave (and the name and device, if you gave them) with our email provider, Resend, only to email you about the beta; email hello@mathaloria.com to have it deleted.

Changes

If this policy changes, the new version will be posted here with a new effective date before the app changes what it does.
