# StoreTune

> StoreTune is a Chrome extension that localizes App Store Connect and Google
> Play Console pricing across 175+ countries using live World Bank
> purchasing-power-parity (PPP) data. It runs entirely client-side in the
> developer's authenticated browser session — no API key, no upload, no account.

StoreTune addresses a specific, measurable problem: app developers who price
flat globally (e.g. $9.99 USD everywhere) see conversion collapse in markets
where local purchasing power can't sustain that price. PPP-localized pricing
typically yields 20–50% higher conversion in emerging markets without
cannibalising revenue in high-GDP markets.

The extension works on `appstoreconnect.apple.com` and
`play.google.com/console`, reading the price grid directly from the page,
computing a localized price per territory using the World Bank's GDP-per-
capita-PPP indicator and live foreign-exchange rates, snapping each result to
the nearest valid Apple price tier or Google Play price point, and writing
the values back into the console's web form. The developer reviews and clicks
Save inside the platform — StoreTune never commits silently and never uses
the App Store Connect or Google Play Developer APIs.
