The F-Droid store on Android does that. If nothing is mentioned, the application does not track. For applications with tracking, a tracking anti-feature label is shown under the section "This app has features you may not like". Other labels exist, like "has non-free addons", or "the app contains non-free parts upstream". For an example of such a label: https://f-droid.org/fr/packages/org.mozilla.fennec_fdroid/ https://f-droid.org/fr/packages/org.mozilla.fennec_fdroid/ It makes me think that a catalog like OpenFoodFacts but for software with such anti-features listed could be an idea.
