Privacy Policy

CaLinkr respects your privacy. This policy explains what data we collect and how we use it.

1. Data We Collect

We store the following data in our database: link titles, descriptions, prices, and creator wallet addresses (public blockchain data). For purchases, we store the transaction hash and optionally the buyer wallet address if a connected wallet was used.

2. Blockchain Data

All Cardano transactions are publicly visible on the blockchain. We do not control or obscure on-chain data. Wallet addresses are pseudonymous public identifiers — not personal data in the traditional sense.

3. No Tracking

We use Vercel Analytics for anonymous page view statistics. No cookies are set, no personal profiles are built, and no data is sold to third parties.

4. Third-Party Services

We use Blockfrost to verify on-chain transactions (subject to their privacy policy) and Railway for database hosting.

5. Data Deletion

Creators can delete their links and associated data at any time via the Dashboard. Transaction records on the Cardano blockchain cannot be deleted as they are immutable.
