Privacy Policy

Who we are

Cindrel ("Cindrel", "we", "us") is a product of Cindrel LLC, a Wyoming limited liability company. Cindrel provides a non-custodial software interface to smart contracts deployed on Robinhood Chain. We do not take custody of your funds, hold your private keys, or operate as a bank.

You can contact us about privacy.

You use Cindrel without an account

Using the Cindrel app requires no sign-up, no email, and no name. You interact with the smart contracts directly from your own self-custodial wallet. Because there is no account, there is no account profile for us to build, store, or lose.

• We do not require or collect your name, email address, phone number, or government identity to use the app.
• We do not run advertising or behavioral-tracking pixels, and we do not sell or rent personal data — ever.
• We cannot access your wallet, your seed phrase, or your private keys, and we never ask for them.

Information involved when you use the app

A small amount of data is unavoidably involved in delivering a web app that reads a public blockchain:

• Public on-chain data. Your wallet address and its transactions are public on Robinhood Chain by nature. When you connect a wallet, the app reads your address and on-chain position through blockchain RPC endpoints to display your balances. This data lives on a public ledger we do not control and cannot alter or delete.
• Technical delivery data. Like any website, our hosting and content-delivery infrastructure processes basic request metadata (such as IP address, timestamp, and browser type) to serve pages and protect against abuse. This is standard server logging, not profiling.
• Local storage. The app may store small amounts of data in your browser (for example, interface state) so it works correctly. This is not used for advertising or cross-site tracking.

Third-party services

Cindrel relies on a few third parties to function. Each has its own privacy practices, and where they receive data (such as your IP address) they act as independent controllers or as our processors:

• Hosting and content delivery — serve the website and process request logs for delivery and security.
• Blockchain RPC providers — endpoints for Robinhood Chain that receive your requests when the app reads or submits on-chain data.
• Wallet providers — the self-custodial wallet you choose (for example, a browser wallet) is governed by that provider’s own terms and privacy policy.
• Font delivery — a third-party font service may receive your IP address in order to serve typefaces.
• Card issuing partner (future). When the Cindrel card becomes available, identity verification (KYC) will be performed by a regulated third-party card issuer under its own privacy policy and legal obligations. Cindrel does not carry out that verification, and any identity documents you provide for a card are handled by that partner, not stored by Cindrel as part of the app.

How the data is used

The limited data described above is used only to operate, secure, maintain, and improve the app, and to comply with applicable law. It is not used for advertising, and it is not sold.

Sharing

We do not sell personal data. We share the limited data described above only with the service providers listed above so the app can function, and where we are legally required to do so (for example, in response to a valid legal request), or to protect the rights, safety, and security of users and the service.

Security

We design the app to minimize the data at stake — the strongest protection is not collecting information in the first place. We apply reasonable technical measures to the systems we control. No method of transmission or storage is perfectly secure, and the security of your funds ultimately depends on you keeping your wallet and private keys safe. We can never recover a lost key or reverse an on-chain transaction.

Your choices and rights

Because we hold little or no personal data about you, there is usually nothing tied to an identity for us to retrieve or erase. Where applicable data-protection law gives you rights over any personal data we do process, you may contact us to exercise them, and we will respond as required by law.

Eligibility and international use

Cindrel is intended for users who are at least 18 years old and who are not located in, or residents of, any jurisdiction where use of the app is prohibited or restricted, and who are not subject to applicable sanctions. The app is not directed to children, and we do not knowingly collect information from anyone under 18.

Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. Material changes will be reflected here; your continued use of the app after an update means you accept the revised policy.
