Privacy Policy

Last updated: October 12, 2026

This Privacy Policy describes how Idle Runner ("the Game", "we", "us") collects, uses, and shares information when you use our mobile application and this website.

Data controller: BLACKBYTE sp. z o.o., ul. Wdzięczna 24, 61-313 Poznań, Poland (KRS 0000930720, NIP 7773380847, REGON 520353701). Contact for questions and data requests: contact@idlerunner.app.

Where a rule differs between app versions, it is marked. Everything not marked applies to every version of the Game.

1. Information We Collect

• Game Progress: Your save data (upgrade levels, currency balances, achievements) is stored locally on your device. If you sign in with an account, a copy is stored on our servers, transmitted over an encrypted connection (TLS).
• Recent Backup (no account needed): To protect players from losing progress when the operating system clears the app's local data, the Game may also upload a copy of your save tied to a random device identifier, even if you have not created an account. This backup is kept for a rolling 10 days from your last sync and is then deleted automatically. It is used only to restore your progress, for aggregate statistics, and to detect save-file manipulation. You can request its deletion at any time - from the in-game settings (where available) or by contacting support with your device identifier.
• Device Information: We may collect device model, OS version, and a random anonymized identifier for analytics and crash reporting.
• In-game economy diagnostics: To protect your progress and detect fraud, we keep a first-party record of changes to your in-game diamond balance (what was spent, earned or granted, and the resulting balance), tied to your account or a random device identifier. It is kept for up to 180 days and is deleted when you delete your account or your account-less backup.
• Ad Data: Ads are served through the Unity LevelPlay mediation platform, which requests ads from advertising networks (currently Google AdMob, Meta Audience Network, Unity Ads and Liftoff). These partners may collect device identifiers and usage data in accordance with their own privacy policies. We show a GDPR/UMP consent dialog before any ad data is collected.
• Public Ranking: The Game has a public leaderboard. It shows your in-game nickname, a random pseudonymous player ID, your hero, your rank/category/world, and your best-wave score. Your email, account ID, currency balances, purchases, and full save data are never shown publicly.
  • From version 1.4.0: the leaderboard is ON by default, for accounts and for players without an account, and the Game tells you so the first time you open that version. If you had already chosen to stay off the board, that choice is kept.
  • Earlier versions: the Game showed a consent dialog before you could take part in the leaderboard.
  • In every version you can turn it off at any time in Settings. Turning it off removes you from the public board (your underlying progress is unaffected and is kept until account deletion).
• Website: This website uses Google Analytics to measure visits to its pages (pages viewed, approximate region, device and browser type). Google may set cookies for this purpose; see Google's privacy policy below.

2. How We Use Information

• To save and restore your game progress.
• To display relevant advertisements.
• To improve game balance and fix bugs via aggregated analytics.
• To operate the public leaderboard, including moderation and abuse prevention.

3. Third-Party Services

The Game uses the following third-party services that may collect data:

• Unity LevelPlay (ad mediation) — Privacy Policy
• Google AdMob — Privacy Policy
• Meta Audience Network — Privacy Policy
• Unity Ads — Privacy Policy
• Liftoff — Privacy Policy
• Firebase Analytics & Crashlytics — Privacy Policy
• Google Analytics (this website) — Privacy Policy

4. Payment Data

All in-game purchases are processed by the app store you use (Google Play or the Apple App Store). We do not collect, store, or have access to your credit card number, CVV, or other sensitive payment credentials. We receive only a purchase confirmation and the purchased item details from the store to fulfill your order.

5. Children's Privacy

The Game is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us so we can delete it.

6. Data Retention & Deletion

Local game data can be deleted by uninstalling the app or using the in-game "Reset Progress" option. Cloud Save data is deleted upon account deletion request.

The account-less Recent Backup (see section 1) is kept for a rolling 10 days from your last sync and is then deleted automatically, together with any of your device-linked data derived from it. We may keep anonymous, aggregated statistics that do not identify you or your device. You can also have your backup deleted immediately - from the in-game settings (where available) or by contacting us with your device identifier (shown in the game's support screen). An optional in-game display name you set without an account is stored alongside the device identifier and is removed the same way.

7. Your Rights

Depending on your jurisdiction (GDPR, CCPA), you may have the right to access, correct, or delete your personal data. Contact us at the address below.

8. Changes to This Policy

We may update this policy from time to time. The updated version will be indicated by the "Last updated" date at the top.
