# Papermint Studio > Papermint Studio is an independent studio making small, private, pay-once apps for iPhone, iPad and Mac. No ads, no tracking, no accounts and no subscriptions. The apps do their work on the device; the one exception is Sketchy, which sends a page description or a chosen photo to draw it and then discards it. Papermint makes one focused app at a time and finishes it properly. Every app follows the same rules: - Private by design: no ads, no tracking, no selling of data. Transcription, photo analysis and search run on the device. Sketchy is the one app that uses a server: the description you type, or the one photo you pick, is sent to draw the page and then discarded. - Never a subscription: pay once, or top up as you go. - No accounts: nothing to sign up for. - Native to each platform: built with Apple's own frameworks for iPhone, iPad and Mac.
