Terms of Service

1. Eligibility & Account

WindFolder is intended for players aged 3 and older. By using the Service, you represent and warrant that:

• You are at least the minimum age required by the laws of your jurisdiction to enter into a binding agreement.
• If you are under 18 years of age, you have obtained verifiable consent from your parent or legal guardian.
• You are not barred from using the Service under applicable law.

WindFolder integrates with Google Play Games Services and Apple Game Center for leaderboard and achievement features. By signing in with your gaming account, you also agree to the respective platform's terms of service. Your gaming profile data (display name, avatar) may be visible on public leaderboards.

2. License to Use

Subject to these Terms, WindFolder Studio grants you a limited, personal, non-exclusive, non-transferable, revocable license to install and use WindFolder solely for your personal, non-commercial entertainment purposes.

This license expressly excludes the right to:

• Sell, sublicense, or commercially exploit any part of the Service or its content.
• Copy, distribute, publicly display or perform the game or its assets outside of normal in-app use.
• Modify, translate, adapt, or create derivative works based on WindFolder or any of its assets (including but not limited to plane sprites, weather effects, UI elements, audio tracks, and source code).
• Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of WindFolder.
• Remove or alter any proprietary notices, labels, or marks in or on the Service.

3. Intellectual Property

All content within WindFolder — including without limitation all 2D paper plane sprites (a large and growing collection of unique designs), weather visual effects (fog, sandstorms, rain), buff and debuff icon artwork (Feather Glide, Magnet, Turbo Dash, Future Path, Origami Crane, Eraser Shield, Wet Paper, Frozen Tail), tornado and balloon obstacle artwork, the crystal currency icon, background layer artwork, UI designs, sound effects, background music, the WindFolder logo, the game engine code, physics systems, and all associated documentation — are the exclusive intellectual property of WindFolder Studio, protected under applicable copyright, trademark, and trade secret laws.

The WindFolder name, logo, and all related marks are trademarks of WindFolder Studio. You may not use these marks without our prior written permission.

Unauthorized reproduction, distribution, public performance, public display, or extraction of any game asset is strictly prohibited and may result in civil and/or criminal liability.

4. Game Content & Gameplay Rules

WindFolder is an endless paper plane runner. Core gameplay rules are as follows:

• Objective: Guide your paper plane as far as possible, avoiding obstacles (ground, balloons, terrain), collecting coins, and using power-up buffs.
• Physics System: The plane's flight is governed by simulated aerodynamics including horizontal velocity (v_x), vertical velocity (v_y), stall mechanics, and tilt angles. These systems are defined by us and may be adjusted through updates.
• Buffs: Beneficial collectibles (Feather Glide, Magnet, Turbo Dash, Future Path, Origami Crane Companions, Eraser Shield) provide temporary advantages with defined durations. Their mechanics may be rebalanced in future updates.
• Debuffs: Detrimental collectibles (Wet Paper, Frozen Tail) apply temporary negative physics effects. They are part of the intended game design.
• Hazards: Obstacles, the ground, and hot air balloons cause crashes. A crash ends the current run unless a protective buff (Origami Crane or Eraser Shield) is active.
• Crystals: In-game currency earned through gameplay. See Section 5 for details.

We reserve the right to modify, adjust, or remove any game mechanic, buff, debuff, plane, or feature at any time through updates, without prior notice.

5. In-Game Currency & Virtual Goods

WindFolder features an in-game currency called Crystals (💎) used to unlock paper plane skins, cosmetic upgrades, and optional buff items within the game. You understand and agree that:

• No Real-World Value: Crystals and all virtual goods (unlocked plane skins, upgrades) are virtual items with no real-world monetary value. They cannot be exchanged for cash, redeemed for any monetary value, or transferred outside of the game.
• No Ownership: You do not own any virtual item or currency. You are purchasing a limited license to access and use virtual items within the Service. WindFolder Studio retains all ownership rights.
• Non-Transferable: Virtual goods and Crystals are non-transferable between accounts and may not be sold, gifted, or traded to other players.
• No Guarantee of Availability: We do not guarantee the continued availability of any specific virtual good, plane skin, or in-game feature. We may modify, retire, or discontinue any virtual item at any time.
• Loss on Termination: Upon termination of your account or the Service, all accumulated Crystals and virtual items are forfeited with no compensation.

6. In-App Purchases & Refund Policy

WindFolder may offer optional in-app purchases (IAP) allowing you to acquire Crystals or special in-game bundles using real money, processed through the Google Play Store or Apple App Store.

• All Sales Are Final: All in-app purchases are final and non-refundable, except where required by applicable consumer protection law or the applicable app store's refund policy.
• Authorized Purchases: By making a purchase, you confirm the transaction is authorized. Parents and guardians are responsible for monitoring and controlling in-app purchases made by minors using their accounts.
• Refund Requests: For refund requests, contact the relevant app store (Google Play or Apple App Store) directly, as WindFolder Studio does not process refunds directly. You may also contact us at support@windfolder.game for assistance.
• Pricing: Prices for in-app purchases are displayed in the app at the time of purchase and may vary by region due to currency exchange rates, taxes, or applicable fees.
• No Pay-to-Win: WindFolder is designed so that all gameplay-relevant content can be earned through normal gameplay. In-app purchases are limited to cosmetic plane skins and Crystal packs. No purchase provides an unfair competitive advantage.

7. Advertising

WindFolder may display third-party advertisements served through Google AdMob and similar platforms. By using the Service, you agree to the display of such advertisements. You understand that:

• Advertising SDKs may collect certain non-personal device data (device type, OS version, ad interaction data) as described in our Privacy Policy.
• You may see reward-based advertisements that, when voluntarily viewed, grant in-game Crystals or other benefits. Viewing such ads is always optional.

8. User Conduct & Fair Play

You agree to use WindFolder for lawful purposes only and in a manner that does not infringe the rights of others. When using the Service, you agree not to:
