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 for devices compatible with the Solana Mobile ecosystem (including the Solana Seeker). The Game runs locally on your device, with optional cloud features — account-based progress sync and global Daily Run leaderboards — for players who connect a Solana wallet. 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 who accepts these Terms on your behalf.
• 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 (e.g., the device-native wallet on Solana Seeker) to use the wallet-connected features, including in-game purchases, cloud sync, and leaderboards.

4. Game Description

OchiJump is a mobile platformer game. The core gameplay loop runs locally on your device. The Game also offers optional online features:

• Cloud progress sync — when you connect a wallet, your progress is saved to our servers so you can restore it across devices.
• Daily Runs & global leaderboards — a rotating daily challenge whose results are submitted to public leaderboards visible to other players.
• Optional purchases — additional locations, visual skins, and game modes that can be unlocked on the Solana blockchain.

All base gameplay is available without any purchase, and the Game remains playable offline; online features simply require connectivity and, in most cases, a connected wallet.

5. Accounts, Cloud Sync & Leaderboards

5.1 Your Account

When you connect your Solana wallet, you create an account identified by your wallet's public address (and your .sol / .skr domain name, if you have one). You are responsible for maintaining control of your wallet; anyone who controls your wallet controls your account.

5.2 Cloud Sync

Your progress — such as experience, unlocked locations, and unlocked skins — is synced to our servers so it can be restored on other devices. We strive to keep this data accurate and available, but we do not guarantee that cloud data will be free from loss, corruption, or interruption, and you are encouraged to treat your local device as your primary save where possible.

5.3 Public Leaderboards

Participation in Daily Runs means your best daily score, together with your wallet address or domain name, is published to a global, public leaderboard that other players can see. Do not participate in Daily Runs if you do not want your wallet address or domain name displayed publicly in this context.

6. Wallet Connection & Non-Custodial Nature

OchiJump integrates with your Solana wallet via the Solana Mobile Wallet Adapter (MWA) protocol. Signing in is performed by having your wallet sign a one-time "Sign In With Solana" message that proves you control the wallet.

We never have access to your private keys or seed phrase. Wallet authorization happens directly between the Game and your device-resident wallet application. TwinPixelsLab does not receive, store, or process your private keys under any circumstances. This means:

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

7. In-Game Purchases (Solana)

7.1 How Purchases Work

When you purchase in-game content (locations, skins, or bundles), 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, and all blockchain transactions are executed and settled by the Solana network, not by us.

7.2 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. Specifically:

• You do not receive a Non-Fungible Token (NFT), a Compressed NFT (cNFT), or any SPL token into your wallet.
• Unlocked content will not appear in your wallet's token list or NFT gallery.
• Unlocked content cannot be sold, transferred to another player, or listed on any NFT marketplace.

This model is equivalent to a traditional in-app purchase, where the Solana blockchain serves as the database instead of a centralized server.

7.3 All Sales Are Final

All purchases are final and non-refundable. Because transactions are confirmed and settled on the Solana blockchain, they are technically irreversible. Once a transaction is confirmed by the network, TwinPixelsLab has no ability to reverse it or return funds, regardless of the reason. By initiating a purchase, you acknowledge and accept that no refunds will be issued.

7.4 Purchase Failure

If a transaction is rejected by the network (e.g., insufficient SOL balance, network congestion), no SOL will be deducted and the item will not be unlocked. You may try again. If a transaction appears confirmed on-chain but content is not unlocked in-game, please contact us and we will investigate the on-chain record.

8. Network Fees

Each Solana blockchain transaction requires a small network fee (denominated in lamports, a fraction of SOL). These fees are paid directly to the Solana validator network and are not revenue for TwinPixelsLab. The fee amount is determined by current network conditions and is displayed by your wallet app before you confirm a transaction.

9. Risk Disclosure

You acknowledge and accept the following inherent risks:

• Price Volatility. The value of SOL can fluctuate significantly. We are not responsible for any financial loss resulting from changes in the market value of SOL.
• Transaction Failure. Network congestion or insufficient SOL balance may cause a transaction to fail. We are not liable for failed transactions.
• Smart Contract Risk. While we have taken care in developing our on-chain program, 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 and your account progress tied to that wallet may be permanently inaccessible. We cannot recover content or accounts tied to a lost wallet.

10. Fair Play & Anti-Cheat

OchiJump's leaderboards are meant to be fair. To protect the integrity of the Game and the experience of honest players, we operate anti-cheat measures and reserve the right, at our sole discretion and without prior notice, to take any of the following actions if we detect or reasonably suspect cheating, exploiting, score manipulation, use of bots or automation, tampering with or modifying the game client, or any other unauthorized manipulation of the Game or our systems:

• Shadow ban — hide or exclude your scores from the public leaderboards while you may continue to play (your submitted scores simply will not appear publicly);
• Reset your progress or remove illegitimately obtained progress, scores, or unlocked content from our cloud systems;
• Suspend or terminate your account and your access to the online features of the Game.

These enforcement actions apply to cloud-side data and services that we control — leaderboards, cloud-saved progress, and account access. They do not, and cannot, alter on-chain records: any content you legitimately purchased on the Solana blockchain remains owned by your wallet, as we have no ability to reverse or modify on-chain transactions (see Sections 6 and 7).

We are not obligated to disclose our anti-cheat methods, and a decision to take action under this Section is not a waiver of any other rights or remedies available to us.

11. 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 and is protected by applicable copyright and trademark laws.

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, or distribute any part of the Game.
• Reverse-engineer, decompile, or disassemble the Game's code.
• Use the Game's assets for any commercial purpose without our written consent.

12. Prohibited Conduct

You agree not to:

• Use cheats, exploits, automation software, bots, or any unauthorized third-party tools, or otherwise manipulate gameplay, scores, or leaderboards.
• Modify, tamper with, reverse-engineer, or interfere with the game client or its communication with our servers.
• Attempt to disrupt or gain unauthorized access to the Game, our backend, our smart contracts, or related systems.
• Use the Game to engage in any fraudulent, deceptive, or illegal activity.
• Impersonate TwinPixelsLab or any other person or entity.

Violations of this Section may result in the enforcement actions described in Section 10.

13. 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.

We do not warrant that the Game or its online features will be uninterrupted, error-free, secure, or free of harmful components, or that cloud-saved data or leaderboards will always be available or free from loss.

14. 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, INCLUDING ANY LOSS OF PROGRESS, SCORES, OR ACCOUNT DATA.

OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF THESE TERMS SHALL NOT EXCEED THE TOTAL AMOUNT YOU PAID FOR IN-GAME PURCHASES IN THE 90 DAYS PRECEDING THE CLAIM.

15. 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 arising under these Terms shall be subject to the exclusive jurisdiction of the courts located in Ukraine.

16. Changes to These Terms

We may update these Terms from time to time. When we do, we will update the "Last Updated" date at the top of this page and publish the revised Terms on our website and/or notify you through an in-app notice or an app store update description.

Your continued use of the Game after changes are posted constitutes your acceptance of the revised Terms.

The short version: OchiJump now uses secure cloud services to save your progress across devices and to run global Daily Run leaderboards, and we collect anonymous gameplay telemetry to make the game better. We still never collect your real name, email address, physical address, or location — and we never have access to your private keys or the ability to move your funds. Raw telemetry is permanently deleted after 30 days.

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 for Solana Mobile-compatible devices.

OchiJump began as a fully offline game. As it has grown, we added optional cloud features — cross-device progress saving and global leaderboards — and gameplay telemetry that helps us find bugs and balance the game. This policy reflects that current, hybrid reality and replaces any earlier version that described OchiJump as having no servers.

2. Data We Collect

We've kept data collection deliberately minimal and tied to gameplay. Here is everything we collect through our own cloud backend (hosted on Supabase — see Section 5):

2.1 Account & Wallet Data

• Your Solana wallet's public address (Base58 public key) — used to identify your account so your progress and leaderboard standing follow you.
• Your Solana domain name (.sol / .skr), if you have one — used as your public display name on leaderboards instead of a raw address.
• An internal account identifier derived from your public key (a technical artifact only — not a real email or contact address).

2.2 Gameplay Telemetry

Telemetry can be sent anonymously (tied only to a randomly generated device ID, not to your wallet) or, once you connect a wallet, associated with your account. It includes:

• Run statistics — e.g., height reached, enemies stomped, shards collected, jumps, run duration, and how a run ended.
• App version and platform — e.g., the build number and whether you're on Android or iOS — so we can reproduce and fix bugs on the right devices.
• Anonymous device identifier — a random UUID our app generates on first launch to group your telemetry. This is not your device's hardware identifier or IMEI.

2.3 Game Progress (Cloud Save)

If you connect your wallet, your progress — such as total experience, unlocked locations, unlocked skins, and configuration — is saved to our backend so you can restore it on a new device.

2.4 Leaderboard Entries

When you play a Daily Run, your best score for the day (height and tiebreak stats) is published to a public leaderboard alongside your wallet address or domain name. This is the intended, public-by-design part of the feature.

2.5 Standard Request Metadata

Like any internet service, our infrastructure and providers may log standard technical metadata such as your IP address and request timestamps. We use this only for security, abuse prevention, and rate limiting — not to build a profile of you.

3. Data We Do NOT Collect

Even with cloud features, we still do not collect, store, or process:

• Your real name or username (your public key or .sol/.skr domain is your only identity)
• Your email address
• Your phone number or physical address
• Your geographic location or GPS data
• Your device's hardware identifiers or IMEI
• Biometric data
• Financial credentials, payment card information, or bank details
• Demographic information

OchiJump does not embed third-party behavioral-analytics SDKs (such as Firebase Analytics, Mixpanel, or Amplitude) and does not use third-party crash-reporting services (such as Sentry or Bugsnag). The telemetry described above flows only to our own backend.

4. Wallet Data & Your Keys

This section is important for Web3 users.

• We store your wallet's public address and, optionally, your .sol / .skr domain name. Both are public information by their nature.
• To sign in, your wallet signs a one-time "Sign In With Solana" message that proves you control the wallet. We verify that signature; nothing is moved or spent.
• We never receive, store, or have access to your private keys or seed phrase, and we have no ability to initiate, approve, or reverse any transaction on your behalf. All transaction signing happens inside your own wallet app via the Solana Mobile Wallet Adapter (MWA) protocol.

In short: your keys and your funds never touch our systems.

5. Cloud Services & Where Your Data Lives

OchiJump's cloud features are built on Supabase, a managed cloud platform (PostgreSQL database + serverless functions), which we use to:

• Authenticate your wallet sign-in,
• Save and restore your game progress,
• Record gameplay telemetry, and
• Power the Daily Run leaderboards.

All communication between the Game and our backend uses encrypted HTTPS. Access to the underlying database is restricted; clients can only reach it through our controlled server-side functions, never directly.

6. Telemetry, Analytics & Data Retention

We use the telemetry in Section 2.2 strictly to improve OchiJump — fixing crashes, balancing difficulty, and understanding how features perform across app versions and platforms. We do not sell it.

Retention:

• Raw telemetry (individual gameplay events and run-session records) is permanently deleted 30 days after it is created, by an automated scheduled job. We keep only short-lived, recent data.
• Leaderboard standings and cloud-saved progress persist for as long as you keep an account, because they are features you rely on — your saved game and your scores. You can request deletion (see Section 9).
• Local device data is retained until you uninstall the app.
• On-chain data is permanent and outside our control (see Section 8).

7. 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, including:

What it is	Why
Your Solana wallet's Base58 public key	So you don't have to reconnect your wallet every time you launch the app
Mobile Wallet Adapter session token	Maintains your wallet authorization session without re-prompting
A backend session token	Keeps you signed in to your cloud account so progress syncs without re-authenticating
Game progress, high scores & unlocked content	Your local save data (also mirrored to the cloud when a wallet is connected)
A locally generated anonymous device ID	Groups your telemetry (see Section 2.2)

All locally stored data is deleted when you uninstall OchiJump.

8. Blockchain & Public Data

When you make an in-game purchase, a transaction is submitted to the Solana blockchain. This transaction is permanent and publicly visible.

8.1 What Goes On-Chain

• Your wallet's public address (e.g., 7xKX...3fQz)
• 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

8.2 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.

8.3 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 they are not tradable or transferable. The underlying data is still publicly readable on-chain.

8.4 We Cannot Delete On-Chain Data

Records on a public blockchain are permanent and immutable. TwinPixelsLab has no ability to delete or modify your on-chain transaction history or inventory PDA. The right to erasure does not apply to on-chain data. Anyone can view Solana transactions using public explorers such as Solana Explorer or Solscan.

9. Your Rights and Choices

Disconnecting Your Wallet

You can disconnect your wallet at any time using the in-game Disconnect option. This removes your wallet's public key and session tokens from local storage. You should also revoke OchiJump's authorization within your wallet application.

Deleting Local Data

To delete all locally stored data, uninstall OchiJump from your device.

Deleting Cloud Data

You may request deletion of your cloud account data — your saved progress and leaderboard entries — by contacting us at the address in Section 13. We will verify your control of the wallet and delete the associated records. (Raw telemetry is deleted automatically within 30 days regardless.)

On-Chain Data

On-chain records — including your PlayerInventory PDA and all transaction history — cannot be deleted by TwinPixelsLab or by you. To stop new on-chain data being associated with your wallet, stop making purchases and disconnect your wallet.

10. Android Permissions Explained

android.permission.INTERNET

Used to communicate with our cloud backend (Supabase) for sign-in, progress sync, telemetry, and leaderboards, and with Solana RPC endpoints (Helius and the public Solana network) to read smart-contract state and submit signed purchase transactions. No private keys are ever included in these requests.

android.permission.VIBRATE

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

11. Third-Party Services

OchiJump relies on the following third-party services. We do not control their data practices — please review their privacy policies.

Supabase (supabase.com)

Our cloud backend provider (database, authentication, and serverless functions) for progress sync, telemetry, and leaderboards. As part of operating the service, Supabase may process technical request metadata such as IP addresses. Privacy Policy →

Helius (helius.dev)

Our primary Solana RPC provider. When the Game communicates with the blockchain, requests are routed through Helius, which 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 (e.g., Phantom on Solana Seeker)

Wallet authorization and transaction signing occur within your device's native wallet application via the Solana Mobile Wallet Adapter (MWA) protocol. We never receive your private keys or seed phrase. Please refer to your wallet app's privacy policy.

12. 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.

If you believe a minor has provided personal information in connection with OchiJump, please contact us and we will take appropriate steps.

13. Security

We take the following steps to protect your information:

• HTTPS only. All network communications use encrypted HTTPS connections (android:usesCleartextTraffic="false" in our Android manifest).
• No direct database access. Clients never connect to our database directly; all access flows through controlled, server-side functions with strict row-level security.
• No private key handling. Transaction signing occurs entirely within your wallet app. OchiJump never touches your private key.
• No cloud backup of local data. Android's automatic backup is disabled for OchiJump (android:allowBackup="false").

No method of transmission or storage is 100% secure, but we work to protect your data using industry-standard practices.

14. 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. We will notify you of material changes through an in-app notice or via the app store update notes. Your continued use of OchiJump after changes are posted constitutes your acceptance of the revised Privacy Policy.
