Warmer — Privacy Policy

Last updated: 1 October 2026

Warmer is a word-guessing game for Android developed by MLB Solutions ("we", "us"). This policy explains what data the app handles and with whom it is shared.

No accounts

Warmer does not require an account and we never ask for your name, email address, or contacts. All gameplay data (guesses, results, achievements, streaks, spark balance) is stored only on your device and is deleted when you uninstall the app. If you use the optional leaderboards, a small amount of data is shared as described in "Leaderboards" below, including your approximate location at country level.

Third-party services

The app uses the following Google services, which may collect data as described in the Google Privacy Policy:

• Google AdMob — shows optional rewarded video ads (for example, to earn sparks or unlock practice games). AdMob may process device identifiers (such as the advertising ID), IP address, and coarse ad-interaction data to serve and measure ads. In the European Economic Area and the UK you will be asked for consent before any ads are shown, and you can choose non-personalized ads.
• Google Play Billing — processes optional in-app purchases of sparks. Payment details are handled entirely by Google Play; we never see your payment information.
• Firebase Remote Config — fetches app configuration values (such as prices and feature flags). It uses a randomly generated installation identifier, not tied to your identity.
• Firebase Analytics — may collect anonymous usage and diagnostic events (such as puzzles played and crashes) to help us improve the game.
• Firebase Firestore, Firebase Authentication (anonymous) and Firebase App Check — power the optional leaderboards. When leaderboards are enabled the app signs in anonymously (a random identifier, not linked to your identity), verifies the install with Google Play Integrity, and stores one leaderboard record for you in Firestore. See "Leaderboards" below.

Leaderboards

Leaderboards are optional. While they are enabled, the app publishes a single record for you to a ranking that is visible to all players. That record contains:

• your weekly score ("Embers");
• your country, derived from your mobile network or SIM, or from your device language — never from GPS or precise location;
• a name: your Google Play Games display name, or a randomly generated handle (for example "Ember-4821") if you are not signed in to Play Games or you turn off "Show my Play Games name";
• a random anonymous identifier and a technical Play Integrity token used only to keep out fake or tampered clients.

The record is stored with Google Firebase (Firestore) and refreshed as you play. A record that is not updated for about four months is deleted automatically.

You are in control in the app's Settings:

• Appear on leaderboards — turn this off and your record is deleted and nothing further is submitted, anywhere, until you turn it back on;
• Show my Play Games name — turn this off to compete under the random handle instead of your Play Games name.

Achievements and leaderboard scores are also shared with Google Play Games Services and shown in your Play Games profile.

International data transfers

The services listed above are operated by Google and may process data outside your country of residence, including in the United States. Where this involves transferring personal data from the European Economic Area, the UK, or Switzerland, Google relies on the European Commission's Standard Contractual Clauses (SCCs) as the transfer mechanism. See the Google Privacy Policy and Google's data processing terms for details.

Children

Warmer is a general-audience word game and does not knowingly collect personal information from children.

Data deletion — Warmer

This section explains how to request deletion of any data associated with the Warmer app (developer: MLB Solutions).

How to request deletion

1. Uninstalling the app immediately and permanently deletes all data stored on your device — gameplay history, guesses, achievements, streaks, and spark balance. No further action is needed for this data; nothing is retained on any server.
2. Leaderboard data can be deleted by you at any time, in the app: Settings → turn off "Appear on leaderboards". This deletes your leaderboard record and stops any further submission.
3. For the limited third-party data described below (advertising/analytics identifiers, or any leaderboard record you cannot remove yourself), email lstamenov.mlb@gmail.com with the subject line "Warmer data deletion request". If it concerns analytics, include the analytics ID shown in Settings → "Request analytics data deletion". We will process the request within 30 days and confirm by email once complete.

What is deleted and what is retained

• On-device gameplay data (guesses, results, achievements, streaks, spark balance): deleted immediately on uninstall. Nothing is stored off-device.
• Advertising identifiers (collected by Google AdMob when ads are shown): deleted upon request as described above; no additional retention period.
• Anonymous analytics/diagnostic events and installation identifiers (collected by Firebase Analytics and Firebase Remote Config — not tied to your name, email, or any personal identity): deleted upon request as described above; our configured analytics retention period otherwise applies (2 months) before automatic deletion.
• Leaderboard record (weekly score, country, name/handle, anonymous identifier, stored in Firebase Firestore): deleted immediately when you turn off "Appear on leaderboards" in Settings, or on request; a record left untouched is also deleted automatically after about four months.
• Purchase records for in-app purchases are held by Google Play Billing under Google's own retention policy, not by us — see the Google Privacy Policy to request deletion of that data directly from Google.

Changes

If this policy changes, the updated version will be published at this address.
