Privacy Notice
This Privacy Notice explains how the Smart Challenge app (“the App”) handles your information. We take your privacy seriously — please read this notice before using the App.
1. Overview
The App is an on-chain data analysis tool built on the Solana blockchain. This notice describes what information is collected, how it is used, and the choices available to you.
2. Information We Collect
Wallet connection. The App supports connection through the Solana Mobile Wallet Adapter protocol, including the wallet built into Seeker phones. When connected, the wallet’s public key address and authorization token are stored in local storage on your device so that the connection can be restored automatically the next time you open the App. The App only obtains the wallet public key address for the purpose of querying public on-chain data. It does not access your private key or execute any transactions. You may at any time choose “Unbind Wallet” from the main menu to disconnect and clear the locally stored authorization information.
Leaderboard. When you use the scoring feature, your wallet address, publicly available on-chain transaction statistics (total transaction count and active days) and your scoring result may be uploaded to our servers to generate the leaderboard. This data is derived from public on-chain information and does not contain any private data. You may choose “Do not appear on leaderboard” in the main menu or privacy settings to disable leaderboard reporting. To protect infrastructure resources, we automatically reject obviously non-wallet addresses (such as token mints, contract or program addresses) from scoring and leaderboard requests.
Local storage. The App uses local storage on your device to save your preferences (language, theme, whether you participate in the leaderboard, announcement read status, wallet connection authorization token, etc.). This information is not uploaded to the cloud.
No personal identity data. The App does not collect any personally identifiable information (name, email address, phone number, etc.).
Donations. When you donate SKR tokens to the developer through the in-App donation feature, the App automatically verifies your donation transaction through Solana on-chain data. After successful verification, your wallet address, donation amount and transaction signature will be recorded on our servers to identify you as a donor and provide corresponding benefits (such as a donor badge and priority query access). The donation list displays only wallet addresses (partially hidden) and donation amounts, and does not contain any personally identifiable information.
3. How We Use Data
On-chain data queries are performed through multiple Solana RPC nodes, and the queried content is all public blockchain data.
The scoring algorithm runs entirely locally on your device and does not rely on any external server for computation.
Leaderboard data is used only to display user rankings and will not be used for any commercial purpose or shared with third parties.
Leaderboard-related reporting data is protected against tampering during transmission through encryption and signature verification, in order to prevent malicious forgery of data.
The App may fetch remote configuration and announcements from our servers solely for the purpose of showing you the latest information. This does not involve additional collection of your personally identifiable information.
Your wallet private key is always managed by your wallet application. The App cannot access your private key.
4. Third-Party Services
Solana RPC nodes (Helius, ChainStack, QuickNode, GetBlock, Tatum, etc.): used to query on-chain data.
Solana Mobile Wallet Adapter: used for secure communication with the wallet built into Seeker phones or other compatible wallets, in order to obtain the wallet public key address.
The App does not embed any advertising SDK or user tracking SDK.
5. Security Statement
All transactions must be confirmed and signed by your wallet application before they are executed.
The App does not assume responsibility for the results of on-chain transactions.
Please make sure you understand the irreversible nature of blockchain transactions.
6. App Updates and Announcements
The App periodically checks for updates. Update checks only obtain version information and necessary remote configuration, and do not collect any personally identifiable data.
The App may display an “announcement” popup once after installation or update, to show version changes, feature descriptions or important reminders. The announcement content is delivered by the server but will not contain your personally identifiable information.
App updates are distributed through the Solana dApp Store.
7. Changes to This Notice
We may update this Privacy Notice from time to time. Continued use of the App after an update means you accept the revised terms.
