Privacy Policy

1.Introduction

At OyZinciri, your privacy is a top priority. This platform is designed to provide a secure, decentralized, and transparent voting experience while protecting your personal data and digital identity. This Privacy Policy outlines how we handle and protect your data during your interaction with the OyZinciri platform.

2.Data We Do NOT Collect

Due to the decentralized nature of this platform, OyZinciri does not collect or store any personal information, such as:

• Names
• Emails
• Phone numbers
• IP addresses

Your identity remains anonymous unless explicitly provided by you for specific services.

3.Blockchain Data Transparency

All voting activities and results are stored on the Ethereum blockchain (Sepolia testnet). This ensures transparency and auditability but also means that certain data (like wallet addresses and transactions) are publicly viewable on the blockchain.

4.Use of External Services

The platform interacts with several third-party tools and services to improve functionality. These include:

• •Infura – to securely connect to the Ethereum network
• •Etherscan – to provide public visibility on transaction status
• •Pinata & IPFS – to store and access uploaded files in a decentralized way
• •React Dropzone – for file uploads, processed locally before being pushed to IPFS
• •React Toastify – for frontend notification purposes, no data is collected by it

5.Cookies and Tracking

OyZinciri does not use cookies or browser tracking tools. All interactions occur directly through your browser and wallet connection (e.g., MetaMask). We do not track or log your browsing behavior.

6.Wallet Authentication

Authentication in OyZinciri is conducted via wallet signature (e.g., MetaMask). We do not have access to your private key or seed phrase at any time. You are responsible for the security of your wallet and private keys.

7.File Uploads & Content

Any files uploaded (e.g., for supporting a vote) are pinned on IPFS using Pinata. These files are stored on decentralized nodes and may be publicly accessible through IPFS gateways if someone has the file hash. Avoid uploading sensitive or personal files.

8.Data Protection & Security

OyZinciri employs industry-standard practices to protect data and smart contract interactions:

• •All interactions are encrypted via HTTPS
• •Smart contracts are protected using OpenZeppelin security libraries
• •Access control for administrative operations is enforced through the blockchain logic

9.Your Rights

Since we do not store your personal data, there is no personal information we can edit, delete, or share. However, you have full control over your blockchain wallet and transaction history.

10.Changes to This Policy

This Privacy Policy may be updated from time to time as the platform evolves. When we do, the "Effective Date" at the top will be updated. We recommend reviewing this page periodically.
