Privacy Policy
Last updated: November 14, 2025
1. Introduction
This Privacy Policy ("Policy") describes how the sTFuel Protocol ("Protocol", "we", "us", or "our") collects, uses, and protects information when you interact with the Protocol's smart contracts, website, and services (collectively, the "Services"). By using the Services, you agree to the collection and use of information in accordance with this Policy.
This Policy is governed by Swiss law and complies with the Swiss Federal Data Protection Act (FADP) and the General Data Protection Regulation (GDPR) where applicable.
2. Information We Collect
2.1 Blockchain Data
The Protocol operates on public blockchain networks. All transactions, wallet addresses, and interactions with smart contracts are publicly visible on the blockchain. We do not control or have the ability to delete this information, as it is permanently recorded on the blockchain.
- Wallet addresses
- Transaction hashes and amounts
- Smart contract interactions
- Blockchain transaction history
2.2 Website Usage Data
When you visit our website, we may collect certain information automatically:
- IP addresses
- Browser type and version
- Device information
- Pages visited and time spent
- Referral sources
2.3 Wallet Connection Data
When you connect your wallet to interact with the Protocol, we may access:
- Public wallet addresses
- Token balances (read-only)
- Transaction signing requests (processed locally in your wallet)
We do not have access to your private keys, seed phrases, or any other sensitive wallet information. All transactions are signed locally in your wallet and we never store or transmit private keys.
3. How We Use Information
We use the collected information for the following purposes:
- To provide and maintain the Services
- To process transactions and smart contract interactions
- To improve and optimize the Protocol and website
- To analyze usage patterns and Protocol performance
- To ensure security and prevent fraud
- To comply with legal obligations
4. Data Storage and Security
Blockchain data is stored on decentralized networks and cannot be deleted or modified. Website usage data may be stored on servers, which we take reasonable measures to secure. However, no method of transmission over the internet or electronic storage is 100% secure.
We implement appropriate technical and organizational measures to protect your information, but we cannot guarantee absolute security.
5. Third-Party Services
The Protocol may integrate with third-party services, including:
- Wallet providers (e.g., MetaMask, WalletConnect)
- Blockchain networks and nodes
- Analytics services
- Hosting and infrastructure providers
These third parties may collect information in accordance with their own privacy policies. We are not responsible for the privacy practices of third-party services.
6. Your Rights Under Swiss Law
Under Swiss data protection law, you have the following rights:
- Right to Information: You have the right to request information about the personal data we process about you.
- Right to Rectification: You can request correction of inaccurate data.
- Right to Erasure: (limited): You may request deletion of data, subject to legal and technical limitations (blockchain data cannot be deleted).
- Right to Object: You can object to certain processing activities.
- Right to Data Portability: You may request a copy of your data in a structured format.
Important: Due to the immutable nature of blockchain technology, data recorded on the blockchain cannot be deleted, modified, or rectified. We can only assist with data that is stored off-chain.
7. Data Retention
Blockchain data is permanently stored and cannot be deleted. Off-chain data will be retained only as long as necessary to fulfill the purposes outlined in this Policy, comply with legal obligations, resolve disputes, and enforce our agreements.
