Privacy Policy

Last updated: March 2026

1. Information We Collect

MARNYL is designed with privacy in mind. We collect minimal data:

Wallet Address — Your public blockchain address when you connect your wallet. This is inherently public on the blockchain.
Display Name — If you voluntarily set a colonist name, it is stored in our database linked to your wallet address.
Transaction Data — All purchase transactions are recorded on the Base blockchain and are publicly visible.
Analytics — We use Yandex.Metrica to collect anonymous usage statistics (pages visited, device type, browser). No personal data is tracked.

2. Information We Do Not Collect

Email addresses
Real names or identity documents
Private keys or seed phrases
IP addresses for identification purposes
Location data

3. How We Use Your Information

Display your owned plots on the map
Show your display name to other users
Generate your unique Martian avatar from your wallet address
Improve the platform based on anonymous analytics

4. Blockchain Data

All NFT ownership data is stored on the Base blockchain and is publicly accessible. This includes your wallet address, purchased plots, and transaction history. Blockchain data cannot be deleted or modified — this is a fundamental property of blockchain technology.

5. Cookies

We use minimal cookies and localStorage to:

Remember your wallet connection preference
Store your display name locally
Analytics cookies (Yandex.Metrica)

6. Third-Party Services

Base / Ethereum — Blockchain network for NFT transactions
Yandex.Metrica — Anonymous website analytics
Wallet providers — MetaMask, Coinbase Wallet, etc. are third-party services with their own privacy policies

7. Data Security

We take reasonable measures to protect the data we store. However, no internet transmission is completely secure. Your wallet security is your responsibility — never share your private keys.

8. Children

MARNYL is not intended for users under 18 years of age. We do not knowingly collect data from minors.

9. Changes

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date.
