1. Overview

These Terms of Service ("Terms") govern your use of OchiJump, a mobile platformer game ("Game") developed and published by TwinPixelsLab ("we," "us," or "our").

OchiJump is designed exclusively for devices compatible with the Solana Mobile ecosystem (including the Solana Seeker). By downloading, installing, or playing the Game, you agree to these Terms in full.

2. Acceptance of Terms

By accessing or using OchiJump in any way, you confirm that you have read, understood, and agree to be bound by these Terms and our Privacy Policy. If you do not agree with any part of these Terms, do not use the Game.

3. Eligibility

• You must be at least 18 years of age to use the Game. If you are between 13 and 17 years old, you may use the Game only with the express consent and supervision of a parent or legal guardian.
• The Game is not intended for children under 13. We do not knowingly permit children under 13 to use the Game.
• You must have access to a compatible device and a self-custodied Solana wallet to use in-game purchase features.

4. Game Description

OchiJump is a single-player mobile platformer game. Gameplay is entirely local — the game runs on your device with no connection to TwinPixelsLab servers during play.

The Game includes optional in-game content (additional locations, visual skins, and game modes) that can be unlocked via purchases on the Solana blockchain. All base gameplay is available without any purchase.

5. Wallet Connection & Non-Custodial Nature

OchiJump integrates with your Solana wallet via the Solana Mobile Wallet Adapter (MWA) protocol. We never have access to your private keys or seed phrase. Wallet authorization happens directly between the Game and your device-resident wallet application.

• We cannot recover your wallet or funds if you lose access.
• We cannot reverse, cancel, or refund any on-chain transaction on your behalf.
• The security of your wallet is entirely your responsibility.

6. In-Game Purchases

6.1 How Purchases Work

When you purchase in-game content, the transaction occurs directly between your Solana wallet and our on-chain smart contract (Program ID: DmxfvDvSkm6XEnt7VXMGjpTpt9vkFu7j3vQNbHg8Ds8w on Solana Mainnet-beta). TwinPixelsLab is not an intermediary in this payment.

6.2 Nature of Virtual Goods — Important: These Are NOT NFTs

All in-game purchases are stored as state data in a Program Derived Address (PDA) on the Solana blockchain, linked to your wallet's public key. You are purchasing a non-transferable license to access virtual content within the Game — not a digital asset.

• You do not receive an NFT, cNFT, or any SPL token.
• Unlocked content will not appear in your wallet's token or NFT gallery.
• Unlocked content cannot be sold, transferred, or listed on any marketplace.

6.3 No Refunds

All purchases are final and non-refundable. Because transactions are confirmed and settled on the Solana blockchain, they are technically irreversible. By initiating a purchase, you acknowledge and accept that no refunds will be issued.

6.4 Purchase Failure

If a transaction is rejected by the network, no SOL will be deducted and the item will not be unlocked. If a transaction appears confirmed on-chain but content is not unlocked in-game, please contact us at the address below.

7. Network Fees

Each Solana blockchain transaction requires a small network fee (denominated in lamports). These fees are paid directly to the Solana validator network and are not revenue for TwinPixelsLab.

8. Risk Disclosure

You acknowledge and accept the following inherent risks:

• Price Volatility. The value of SOL can fluctuate significantly.
• Transaction Failure. Network congestion or insufficient balance may cause a transaction to fail.
• Smart Contract Risk. Smart contracts may contain unforeseen bugs or vulnerabilities. Use of on-chain features is at your own risk.
• Wallet Loss. If you lose access to your Solana wallet, your unlocked in-game content may be permanently inaccessible.

9. Intellectual Property

All content within OchiJump — including graphics, audio, game design, code, and the OchiJump name and logo — is the exclusive intellectual property of TwinPixelsLab. You are granted a limited, non-exclusive, non-transferable, revocable license to use the Game for personal, non-commercial purposes only. You may not copy, modify, distribute, reverse-engineer, or use the Game's assets for any commercial purpose without our written consent.

10. Prohibited Conduct

You agree not to use cheats, exploits, bots, or unauthorized third-party tools; attempt to interfere with the Game or our smart contracts; use the Game for fraudulent or illegal activity; or impersonate TwinPixelsLab or any other entity.

11. Disclaimer of Warranties

THE GAME IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, TWINPIXELSLAB DISCLAIMS ALL WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL TWINPIXELSLAB BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF THE GAME. OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM SHALL NOT EXCEED THE TOTAL AMOUNT YOU PAID FOR IN-GAME PURCHASES IN THE 90 DAYS PRECEDING THE CLAIM.

13. Governing Law

These Terms are governed by and construed in accordance with the laws of Ukraine, without regard to its conflict of law provisions. Any disputes shall be subject to the exclusive jurisdiction of the courts located in Ukraine.

14. Changes to These Terms

We may update these Terms from time to time. We will update the "Last Updated" date at the top of this page and publish the revised Terms on our website. Your continued use of the Game after changes are posted constitutes your acceptance of the revised Terms.

The short version: OchiJump has no backend servers. We do not collect your name, email address, location, or any personal identifiers on our own systems. Almost everything stays on your device. The one exception is the Solana blockchain — it is public by design.

1. Who We Are

This Privacy Policy describes how TwinPixelsLab ("we," "us," or "our") handles information in connection with OchiJump, a mobile platformer game available exclusively for Solana Mobile-compatible devices.

2. Data We Do NOT Collect

We do not operate backend servers or databases. As a result, we do not collect, store, or process:

• Your name, username, or email address
• Your phone number or physical address
• Your geographic location or GPS data
• Device identifiers (IMEI, advertising ID)
• Biometric data or financial credentials
• Behavioral analytics or usage telemetry

OchiJump contains no analytics SDKs, no advertising SDKs, and no crash-reporting services.

3. Data Stored Locally on Your Device

OchiJump stores a small amount of data in your device's local storage using the react-native-mmkv library. This data never leaves your device and is never transmitted to TwinPixelsLab servers.

Key	What it is	Why
ochi_wallet_pubkey	Your Solana wallet's Base58 public key	So you don't have to reconnect your wallet every launch
solana_auth_token	Mobile Wallet Adapter session token	Maintains your wallet authorization session
Game progress & high scores	Your in-game records and unlocked content state	Local save data

All locally stored data is deleted when you uninstall OchiJump.

4. Blockchain & Public Data

4.1 What Goes On-Chain

When you make an in-game purchase, a transaction is submitted to the Solana blockchain. This transaction is permanent and publicly visible. The following information is recorded on-chain:

• Your wallet's public address
• The item(s) purchased (encoded as bits in your PlayerInventory account)
• The SOL amount transferred to the OchiJump treasury wallet
• The timestamp of the transaction

4.2 Your PlayerInventory PDA Is Public

Your in-game item inventory is stored in a Program Derived Address (PDA) account managed by the OchiJump smart contract (Program ID: DmxfvDvSkm6XEnt7VXMGjpTpt9vkFu7j3vQNbHg8Ds8w). This account is tied to your wallet's public key and is readable by anyone who queries the Solana blockchain.

4.3 These Are NOT NFTs or Tokens

Your purchased items are stored as technical state records in the PDA — they are not NFT tokens, cNFTs, or SPL tokens. They will not appear in your wallet's token or NFT gallery and are not tradable or transferable.

4.4 We Cannot Delete On-Chain Data

The nature of a public blockchain is that records are permanent and immutable. TwinPixelsLab has no ability to delete or modify your on-chain transaction history or inventory PDA. The right to erasure (right to be forgotten) does not apply to on-chain data.

Anyone can view Solana transactions using Solana Explorer or Solscan.

5. Android Permissions Explained

android.permission.INTERNET

Used exclusively to communicate with Solana RPC endpoints (Helius and the public Solana mainnet) to read the state of the OchiJump smart contract, fetch your existing item inventory, and submit signed purchase transactions. No personal data is included in these requests.

android.permission.VIBRATE

Used to provide haptic feedback during gameplay. No data is collected through this permission.

6. Third-Party Services

Helius (helius.dev)

Our primary Solana RPC provider. Helius may log your IP address and request metadata. Privacy Policy →

Solana Foundation (Public RPC)

Used as a fallback RPC endpoint. Similar logging may apply. Privacy Policy →

Device Wallet App

Wallet authorization and transaction signing occur within your device's native wallet application via the Solana Mobile Wallet Adapter (MWA) protocol. OchiJump communicates with your wallet using a local device intent — we never receive your private keys or seed phrase.

7. Children's Privacy

OchiJump is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. Users between 13 and 17 may use the Game only with parental or guardian consent.

8. Your Rights and Choices

Deleting Local Data: Simply uninstall OchiJump from your device.

Disconnecting Your Wallet: You can disconnect your wallet at any time using the in-game Disconnect option. You should also revoke OchiJump's authorization within your wallet application.

On-Chain Data: On-chain records cannot be deleted by TwinPixelsLab or by you. To stop new on-chain data being associated with your wallet, simply stop making purchases and disconnect your wallet.

9. Data Retention

• Local device data is retained until you uninstall the app.
• On-chain data is permanent by the nature of the Solana blockchain.
• We retain no personal data on our servers because we have no servers that store user data.

10. Security

• HTTPS only. All network communications use encrypted HTTPS connections.
• No cloud backup. Android's automatic backup is disabled (android:allowBackup="false").
• No private key handling. Transaction signing occurs entirely within your wallet app.

11. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by the updated "Last Updated" date at the top of this document. Your continued use of OchiJump after changes are posted constitutes your acceptance of the revised Privacy Policy.
