FastMath Privacy Policy
Effective 1 October 2026
In short: FastMath is a math game. It has no accounts and no servers of its own, and it never asks for your name, email, photos, contacts or location. Your scores, level and settings stay on your device. Players under 13 see no ads and nothing is collected from them. Players 13 and over may see ads from Google, which collects some device and usage data as described below.
Who can use FastMath
When you first open FastMath it asks for your birth year to choose the right puzzles and settings. We use it only to place you in an age group (under 13, 13–17, or 18 and over) and then discard it. We do not store your birth year. Only the age group is kept, on your device.
- Under 13: no ads, no Game Center, no tracking. Purchases and changes to the age group are behind a "grown-ups only" check. The advertising software is never started.
- 13 to 17: ads are shown, but only non-personalized ones. FastMath tells Google the player is under the age of consent and does not show the tracking prompt.
- 18 and over: ads may be personalized, subject to your choices below.
Information stored on your device
FastMath keeps the following on your device only, so the game can work:
- Your age group, level and experience points, scores, streaks, achievements and statistics.
- Your settings (theme, sound, haptics, which operations you practice).
- A short list of recent mistakes, for the optional Premium "review mistakes" screen.
This information is not sent to us. Deleting the app deletes it. "Reset progress" in Settings erases it too.
Game Center (13 and over)
Players 13 and over can sign in to Apple's Game Center to post scores to leaderboards and earn achievements. This is handled by Apple under Apple's Privacy Policy; FastMath receives no personal information from it. Game Center is never turned on for players under 13.
Purchases
FastMath Premium and Remove Ads are one-time purchases through Apple's App Store. Apple processes the payment and we never see your payment details. FastMath checks with Apple whether your Apple ID owns a purchase, so that "Restore Purchases" works.
Advertising (players 13 and over)
Free players aged 13 and over may see ads from Google AdMob (the Google Mobile Ads SDK and Google's User Messaging Platform). Google may collect these data from your device to show and measure ads:
| Data | Used for |
|---|---|
| Device identifiers, including the advertising identifier (IDFA) if you allow tracking | Advertising, analytics |
| Approximate location (derived from IP address) | Advertising, analytics, consent |
| Ad interactions and app usage (for example, ads viewed or tapped) | Advertising, analytics |
| Diagnostics (crash, performance and other diagnostic data) | Analytics, advertising |
For adults, Apple's App Tracking Transparency prompt lets you choose whether Google may use your advertising identifier to track you across apps. If you choose not to allow it you'll still see ads, but they won't be personalized using that identifier. You can change this in iOS Settings › Privacy & Security › Tracking.
Where the law requires it (for example in the EEA, UK and Switzerland), FastMath asks for your consent before ads are personalized. You can change your choice any time in FastMath › Settings › Ad privacy choices.
Google's use of this data is governed by Google's Privacy Policy and how Google uses information from sites or apps that use its services. Players who buy Premium or Remove Ads do not see ads.
Children
FastMath is a general-audience game that children can enjoy. For players under 13 it collects no personal information, shows no ads, starts no advertising or analytics software, and leaves online features off. If you believe a child has been given access to ads or online features by choosing an incorrect birth year, a parent can change the age group in Settings, or email us and we will help.
Your choices
- Turn off tracking or ad personalization in iOS Settings or FastMath's Settings.
- Buy Remove Ads or Premium to stop all ads.
- Reset progress, or delete the app, to remove everything stored on your device.
Changes
If this policy changes, we'll update it here and change the date at the top.
