Your searches, the suggestions while you type, and the new tab page. Only while Shodhya is your search engine; you can pick another in Settings → Search.

ublockorigin.github.io, ublockorigin.pages.dev, cdn.jsdelivr.net, raw.githubusercontent.com, malware-filter.gitlab.io, malware-filter.pages.dev, curbengh.github.io, publicsuffix.org, pgl.yoyo.org. The lists of ads, trackers and malware sites to block; nothing about you is sent. Switching uBlock Origin off stops them.

Installing an extension from the Chrome Web Store, and update checks for the extensions you installed from it.

The Widevine module some streaming sites need. Only after you turn on protected content in Settings → Privacy; turning it off deletes it.

The live caption and translation models, downloaded once, after Tark tells you the size, the first time you turn on captions or Translate (or from Settings → Live captions), without cookies. Captions and translations are made on your Mac: no audio or text is sent anywhere. The captions history (☰ Earlier) is kept in memory only, never on disk, and goes when you turn captions off, leave the site or close the tab.

On macOS 26, captioning English, Spanish and the other languages macOS handles uses the Mac's own speech recognition and Translation; the first time, macOS downloads that language from Apple. Tark sends Apple nothing.

This site. Tark asks for gettarka.com/appcast.xml once a day to see whether there is a new version, and downloads it from here. The request carries only Tark's version, like any download; no system profile, nothing else about you.

The ad and tracker lists, signed, which Tark checks before using them. Once a day on Wi-Fi, every three days on mobile data.

The Indian-language suggestions' model and word lists, downloaded once after you say yes (on Wi-Fi unless you choose "Download now"). The suggestions are worked out on your phone; what you type is never sent for them.

For the APK from this site only: once a day Tark reads the small index of the newest version, with nothing about you or your phone. Installed from Google Play, Tark never checks: Play updates it.
