Is JOSEPHA safe?

Low risk

JOSEPHA sends the current page URL and location/account metadata to Firebase and PostHog during price searches.

When a price search starts, JOSEPHA reads the current page URL and writes it to a Firestore best-price request with language, country, device distinct ID, and signed-in user ID when available. It also records a PostHog event with the URL, and on first run it contacts ipwhois.pro to derive and cache the user's country from their IP address.

Where it sends data
