Privacy Policy - Sliding

Effective Date: August 13, 2026

Welcome to Sliding. This Privacy Policy explains how we collect, use, and disclose information when you play our mobile game.

1. Information We Collect

We collect only what the game needs in order to work.

a. Account information

Sliding uses Firebase Authentication (a Google service) to give each player an account. When you sign in, Google provides us with a unique account identifier. We use this identifier solely to link your game progress to you and to make sure that only you can modify your own records.

b. Information you choose to provide

Display name: the name you choose is shown next to your score on the public leaderboard and to other players you compete against. Please do not use your full legal name or any information you would not want other players to see.

c. Gameplay information

Progress and scores: your total stars, completed stages, weekly score, and the time your record was last updated. This is stored in Google Firebase so that your progress survives a change of device and can appear on the leaderboard.
Multiplayer sessions: when you play a head-to-head race, the game creates a temporary room holding the puzzle setup, each player’s account identifier, and each player’s progress and finish time. This exists only for the duration of the match.

d. Information collected automatically by third parties

Device Information: device type, operating system version, and advertising identifiers (such as the Google Advertising ID).
Approximate Location: a coarse location derived from your IP address, used by advertising partners to serve regionally relevant ads. We never access your precise GPS location.

We do not collect your phone number, contacts, photos, calendar, files, or precise location.

2. Information Visible to Other Players

Please be aware that the following is public to every signed-in player of the game: your chosen display name, your total stars, your weekly score, and your number of completed stages. Nothing else about you is shown to other players — in particular, your email address is never displayed.

3. Third-Party Services & Advertising

Our app is free to play, and to support its development we use Google AdMob to display advertisements. AdMob may collect and use data (such as advertising identifiers) to serve personalized ads based on your interests. We also use Google Firebase (Authentication and Realtime Database) and Google Play Services for core app functionality.

If you are located in the European Economic Area, the United Kingdom, or Switzerland, you will be asked for your consent before any personalized advertising data is used. You can change your choice at any time from the privacy options available in the app’s settings.

For more information on how our partners handle your data, please review their privacy policies:

4. How We Use Your Information

The collected information is used strictly to:

Save your progress and restore it when you sign in on another device.
Display leaderboards and run head-to-head matches.
Make sure that only you can modify your own scores.
Serve relevant advertisements to keep the game free for everyone.

We do not sell your information, and we do not share it with anyone other than the service providers named above.

5. Children’s Privacy

Our game is designed for a general audience and is not intended for children under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we will delete it immediately from our servers.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We advise you to review this page periodically for any changes. Any modifications are effective immediately after they are posted on this page.

8. Account & Data Deletion

In accordance with Google Play’s Data Safety and account deletion policies, you may delete your account and all associated data at any time.

Or request deletion by email: write to info@leadermas.com with the subject “Account Deletion Request”, stating the display name shown on your leaderboard entry. We will action the request within 30 days.
What is deleted: your authentication account, your leaderboard entries (both all-time and weekly), and any multiplayer records associated with you.
Local data: uninstalling the app removes all data stored on your device.
Data Retention: we keep your leaderboard record for as long as your account exists. Temporary multiplayer rooms are discarded after the match. Residual anonymous advertising data held by our partners is generally deleted within 90 days.
