Privacy Policy

Single Hand Studio ("we," "us," or "our") is an independent developer and publisher of apps and games for Solana Mobile. This Privacy Policy explains how we handle information on this website, when you contact the studio, and in our work as a publisher.

We do not sell personal information, we do not use it for advertising, and we will never ask for your wallet seed phrase, recovery phrase or private keys.

Each of our apps has its own privacy policy, linked from its store listing, that explains what the app collects and how that information is used. For anything that happens inside an app, the app's privacy policy applies instead of this one.

• Solana Crystal Miner: Privacy Policy
• Wherewhy: Privacy Policy
• WalkinRunner: in development. Its privacy policy will be published with its store listing.

This website is informational. It has no user accounts, it does not ask you to connect a wallet, and it does not use advertising or analytics cookies or third-party tracking scripts.

Like most websites, our hosting provider automatically processes technical request data, such as your IP address, browser and device information, the page requested, the referring page and the time of the request, to deliver the website, keep it secure and diagnose problems.

If you open a Solana Crystal Miner invite link, the referral code in the link is used only to show the invite on the page.

When you email us or contact us on social media, we receive your email address or account name, your message, any attachments, and any details you choose to include, such as the app you are using, your device or a public wallet address.

We use this information to reply to you, investigate and fix problems, and keep a record of the conversation. Never send your seed phrase, recovery phrase or private keys; we will never ask for them.

• Provide, maintain, secure, and improve this website
• Respond to support requests and communicate with you
• Detect and prevent abuse, fraud, and security issues
• Comply with legal obligations and enforce our Terms of Service

We share information only as needed to run this website and our support channels:

• Vercel, which hosts this website
• Google, which provides our support email inbox
• X, if you contact us there; X's own privacy policy applies to that platform
• Legal authorities, successors, or advisers where required by law, security needs, or a business transfer

We do not sell personal information for money. We do not knowingly share personal information for cross-context behavioral advertising.

Where our apps interact with the Solana blockchain, wallet addresses, transaction signatures, token movements, and NFT records are public by design and may persist indefinitely.

We cannot delete, alter, or hide data that has already been written to the Solana blockchain or stored by third-party wallets, indexers, marketplaces, RPC providers, explorers, or other independent services.

This website does not set cookies for advertising or analytics. Our apps may store information on your device to work properly; each app's privacy policy explains what it stores.

Hosting request data is kept by our hosting provider for a limited period. Support correspondence is kept for as long as needed to resolve your request and keep a record of it, and you can ask us to delete it.

For data held by an app, including account deletion, see that app's privacy policy. Deletion never removes public blockchain data.

We use reasonable technical and organizational safeguards to protect information. No internet, wallet, blockchain, or storage system is completely secure.

We and our service providers may process information in the United States, Ireland, the European Union, and other countries where infrastructure, support, or service providers operate. Where required, we rely on appropriate transfer mechanisms or lawful exceptions.

Depending on your location, you may have rights to request access, correction, deletion, portability, restriction, objection, withdrawal of consent, or information about how we collect, use, retain, and share personal information.

California residents may have rights to know, delete, correct, opt out of sale or sharing, and limit certain uses of sensitive personal information where applicable. We do not sell personal information or share it for cross-context behavioral advertising.

To exercise these rights, contact us using the details below. We may need to verify your request before fulfilling it. Some requests may be limited by public blockchain data, security needs, or legal obligations.

This website is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us and we will take appropriate steps.

Individual apps may set a higher minimum age in their own privacy policy or store listing.

We may update this Privacy Policy from time to time. Updated versions become effective when posted unless a different effective date is stated.
