Cookies & Storage

How Yappr uses browser storage

No Tracking Cookies

Yappr does not use cookies for tracking, analytics, or advertising. We don't set any third-party cookies, and we don't participate in any ad networks or tracking systems. Your browsing activity on Yappr is not monitored or recorded.

What We Store Locally

For the app to function, we use your browser's built-in storage mechanisms. Here's exactly what we store and why:

Session Storage

Most Secure

Automatically cleared when you close the browser tab. Isolated to each tab.

Private Key

Your private key is stored here while you're logged in. This means:

Closing the tab logs you out automatically
Other tabs cannot access your key
The key is never written to disk
Refreshing the page keeps you logged in (same tab)

Local Storage

Persistent

Persists until manually cleared. Shared across tabs on the same domain.

Session Metadata

Your identity ID, cached profile data, and balance. This lets the app remember who you are when you reload the page (though you'll need to re-enter your key if you closed the tab).

App Preferences

Theme settings (dark/light mode) and other UI preferences.

Why This Design?

Security and convenience often conflict. We chose this approach because:

Private keys are sensitive. They should never persist on disk where malware or other users might find them. Session storage provides tab-isolated, memory-only storage.
Session continuity matters. We cache non-sensitive data in local storage so you don't have to fetch your profile every time you reload.
No external dependencies. We don't rely on external cookie services or authentication providers. Everything happens locally in your browser.

Clearing Your Data

You can clear all locally stored data by using your browser's "Clear site data" feature, or by logging out of the app. Clearing this data will log you out and remove all cached preferences. It will not affect your data on the blockchain.
