Privacy Policy

App Name: Schulte Table - Focus Test

Developer: pilyeooong

Last Updated: October 22, 2026

1. Personal Information Collection

This app does not collect any personal information from users. No account registration, sign-in, or contact details are required. The only data sent to a server is the anonymous leaderboard record and the anonymous usage statistics, both described in section 3.

2. Local Data Storage

The app stores the following information locally on your device (using AsyncStorage). Except for the leaderboard record and the anonymous usage statistics in section 3, this data never leaves your device:

• Your recent game history and personal best completion times
• Daily Challenge completion and streak
• Your selected language, grid size, order and mode settings
• Pro purchase status (iOS only — the Android version has no in-app purchase)
• A random leaderboard identifier (see section 3)
• A random identifier for anonymous usage statistics (see section 3)

Uninstalling the app removes all locally stored data.

3. Anonymous World Leaderboard

When you finish a timed round in a ranked configuration (Classic variant, Classic mode, ascending order) or the Daily Challenge, the app sends the following to our server so your time can be placed on the world board:

• A random identifier generated by the app on first use (it is not your account, name, email, phone number or advertising ID, and it cannot be used to identify you)
• Which board the time belongs to (grid size, or the Daily Challenge date)
• Your completion time and number of mistakes

Purpose: operating the world leaderboard (showing top times and your place). Retention: the record is kept on the server as long as the leaderboard operates; only your best time per board is stored. Other players never see the identifier — the board shows a 4-character tag derived from it.

Leaderboard records are stored using Supabase, a cloud database service (https://supabase.com/privacy). Because the identifier is not linked to you, we cannot look up your record from any personal information; you may request deletion by contacting the address in section 8 with the 4-character tag shown next to your entry. If the server is unreachable, the game works normally and no data is sent.

Anonymous usage statistics

To improve the app, it sends part of its usage anonymously to our server (since 1.4.0). What is sent:

• That the app was opened
• For each finished round: its type (regular or Daily), grid size, completion time, whether it counts for the world board, and whether Pro was active when it ended
• That the round setup sheet on the home screen was opened
• That the Pro screen was shown and where it was opened from (iOS)
• Completed purchases — the product name only, with no payment information (iOS)
• That an interstitial ad was shown and at which point

Sent along with it: the platform (iOS or Android), the app version, and a random identifier the app creates for this purpose (separate from the leaderboard identifier). This information is not linked to any account, name or advertising identifier and cannot identify you. Purpose: analysing how the app is used (ads shown, rounds played, app opens). Storage: Supabase (the same service as the leaderboard above). Retention: kept while the service operates, with no automatic deletion. Because it is tied only to the random identifier and cannot be traced to a person, we cannot process requests to delete an individual's statistics.

4. Advertising

This app uses Google AdMob to display banner, interstitial and native advertisements. AdMob may collect device-level data such as:

• Device advertising identifier (IDFA on iOS, AAID on Android)
• IP address, device type, and operating system version
• General location derived from IP address
• Ad interaction data (impressions, clicks)

This data is collected by Google and used in accordance with Google's privacy policy: https://policies.google.com/privacy

The app does not show the App Tracking Transparency prompt and does not use the advertising identifier for cross-app tracking; ads are requested without that permission.

5. Children's Privacy

This app is suitable for all ages and does not knowingly collect personal information from children under 13.

6. Third-Party Services

The app uses the following third-party services:

• Google AdMob — for displaying advertisements
• Supabase — for storing anonymous leaderboard records and anonymous usage statistics
• Apple App Store — for processing the optional Pro purchase on iOS; we do not receive payment details

7. Data Security

The app transmits no personal information. Leaderboard records contain only a random identifier, board, time and mistake count, and usage statistics only the items listed in section 3; both are sent over HTTPS to a database that can only be accessed through validated server functions.
