1. Introduction

This Cookie Policy explains how ChainPortal ("we," "our," or "us") uses cookies and similar technologies when you visit our platform. It explains what these technologies are and why we use them, as well as your rights to control our use of them.

2. What Are Cookies?

Cookies are small text files that are placed on your device when you visit a website. They are widely used to make websites work more efficiently and provide information to website owners.

3. Types of Cookies We Use

3.1 Essential Cookies

These cookies are necessary for the Platform to function properly. They enable core functionality such as maintaining your session, remembering your preferences, and ensuring security. These cookies cannot be disabled.

Session management cookies
Authentication cookies
Security cookies

3.2 Functional Cookies

These cookies allow the Platform to remember choices you make (such as your preferred blockchain ecosystem or theme preferences) to provide enhanced, personalized features.

3.3 Analytics Cookies

We use analytics cookies to understand how visitors interact with our Platform. These cookies help us improve our service by collecting anonymous information about usage patterns. They are set only if you consent to them, and analytics is disabled by default until you do.

3.4 Advertising Cookies

Some pages carry advertising. Sponsorships that we sell and host ourselves set no cookies at all and involve no third party. Where a slot is instead filled by our advertising network (A-ADS), the advert is delivered from that network inside a sandboxed frame, and the network may set its own cookies for frequency capping and click measurement under its own privacy policy.

We do not control those cookies, and we do not share your wallet address, transaction history or any account data with advertisers or with the ad network. Third-party advertising is served only if you consent to it.

4. Cookies We Do Not Use

ChainPortal does not use:

Social media cookies
Cookies that identify you across other websites
Cookies that link your wallet address or on-chain activity to advertising profiles

We do not sell your personal information. Advertising cookies set by our ad network are described in section 3.4 above; they belong to that network, are used for frequency capping and click measurement, and are served only with your consent.

5. Third-Party Cookies

Some third-party services we integrate with may set their own cookies. These include:

Wallet providers (MetaMask, WalletConnect, etc.)
RPC providers
IPFS services (if you choose to use them)
Google Analytics, if you consent to analytics cookies
A-ADS (a-ads.com), our advertising network, if you consent to advertising cookies

We do not control these third-party cookies. Please refer to the respective privacy policies of these services for more information.

6. Local Storage

In addition to cookies, we use browser local storage (IndexedDB) to store your transaction history and preferences locally on your device. This data is never transmitted to our servers unless you explicitly choose to sync your data.

7. Managing Cookies

See what cookies you have and delete them individually
Block third-party cookies
Block all cookies from specific sites

Delete all cookies when you close your browser

Please note that blocking or deleting cookies may impact your ability to use certain features of the Platform. Essential cookies cannot be disabled as they are necessary for the Platform to function.
