LM Media LLC (“we,” “us,” “our”) operates the mobile application
impossible MATH (the “App”). This page explains what
information the App collects, how it’s used, and the choices you have.
Information we collect
impossible MATH is designed to collect as little personal information as
possible. The App collects only the following:
Display name and country code — only if you choose
to submit a leaderboard entry. The name you type and the
two-letter country code you select are sent to our leaderboard
backend (Google Firebase Firestore) so other players can see
your standing on the global leaderboard.
An anonymous device identifier — a per-install UUID
generated locally and used solely to allow you to update your
own leaderboard entry. It is not linked to your Apple ID, email,
or any other personal information we hold.
In-app purchase status — whether you have purchased
the optional “Remove Ads” upgrade. This is handled by Apple’s
StoreKit. We do not see your payment details.
Game Center achievements — when you authenticate
with Apple Game Center, your unlocked achievements are reported
to Apple. We do not separately store this information.
Information we do not collect
We do not collect your real name, email address, phone number, or
precise location.
We do not request access to your contacts, photos, microphone, or
camera.
We do not track you across other apps or websites.
Advertising
The App displays banner advertisements provided by Google AdMob.
AdMob may collect a limited set of advertising identifiers and device
information for the purpose of serving and measuring ads. You can
review Google’s privacy practices at
policies.google.com/privacy.
If you purchase the “Remove Ads” upgrade, the App stops requesting
ads and the AdMob SDK is no longer invoked while ads are removed.
Data we share
We share data with the following service providers, and only to the
minimum extent necessary to operate the App:
Google Firebase / Firestore — stores leaderboard
entries (display name, country code, completion date,
achievements).
Google AdMob — serves banner advertisements.
Apple Inc. — Game Center achievements,
In-App Purchase processing, App Store delivery.
We do not sell, rent, or trade personal information to anyone for
marketing purposes.
Children
impossible MATH is rated 4+. We do not knowingly collect personal
information from children. The leaderboard submission is optional and
asks only for a free-form display name and country code; we recommend
parents supervise the use of the leaderboard feature.
Your choices
You can play the entire game without ever submitting a leaderboard
entry.
You can request deletion of any leaderboard entry tied to you by
emailing impossiblemath@lmmediallc.com
with the display name and country you submitted.
You can disable personalized advertising in iOS Settings →
Privacy & Security → Tracking.
Security
All network communication uses HTTPS / TLS. Leaderboard data is
stored in Google Firebase, which is governed by Google’s standard
security practices.
Changes to this policy
If we change this policy materially, we will update the “Last
updated” date above and, where required, post a notice in the App.
