Mathlings: Geometry & Measure (Android, package com.tapforgestudios.mathlingsgeometry)
TapForge Studios · contact@tapforgeapps.com
Effective October 14, 2026

What stays on the device

Each player profile holds a first name or nickname, an age (4–14) and a chosen buddy, plus game progress: stars, coins, stickers, trophies, the Shape Town buildings, saved Art Studio pictures and minutes played per day. Settings (units of measure, language, sound, reminder, daily time limit, paper size) are stored too. All of this lives only in the app's private storage on the device. It is never sent to us or to anyone else. Android's own device backup may include it if the family has backup turned on in the phone's settings; that backup is governed by Google's policies, not ours.

What we do not do

• No advertising and no advertising ID (the app removes the AD_ID permission).
• No analytics, crash-reporting or tracking services.
• No accounts, sign-in, chat, or sharing between users.
• No location, camera, microphone, contacts or photos access.
• No links, purchases or emails a child can reach: these are all behind a grown-up check.

Purchases

The optional one-time unlock is bought through Google Play. Google processes the payment under Google's privacy policy; we receive no payment details. The app asks Google Play only whether the unlock was bought. If a school discount code is entered, only an internal identifier (not the code, and nothing about the family) is stored on the device.

Read-aloud, notifications and printables

Questions are read aloud with the phone's own text-to-speech engine. The optional daily reminder is a local notification scheduled on the device. Printable worksheets are created on the device; they leave it only if a grown-up chooses to print or share them.

Problem reports

If the app closes unexpectedly, it can prepare a report for a grown-up to send by email. The report contains the app version, the phone model and Android version, the step the app was on and technical error details. Player names are not included; at most it lists which special (non-English) letters appear in them, as character codes, to help fix font problems. Nothing is sent unless a grown-up chooses to send the email.

Children's privacy

The app is designed for children and complies with the Google Play Families Policy, COPPA (US), GDPR-K (EU/UK) and similar laws: we do not knowingly collect personal information from anyone. Because nothing leaves the device, there is nothing for us to access, correct or delete; removing a player in Grown-ups ▸ Progress, or uninstalling the app, erases their data.

Changes and contact

If this policy changes, we will update this page and its date. Questions: contact@tapforgeapps.com · tapforgeapps.com
