1. How We Author & Check Grammar Content

Every grammar guide on GermanLogic maps directly to the 9-module, 78-topic CEFR curriculum (A1 to C1) inside the GermanLogic Android app. Explanations are written in plain English from the perspective of an adult learner, highlighting the structural logic behind German cases, verb-second (V2) word order, separable prefixes, and modal particles rather than forcing rote memorization alone.

2. Fact-Checking DACH Practical & Expat Guides

Practical articles covering German, Austrian, and Swiss life—such as Anmeldung, tax classes, health insurance, rail passes, and work permits—cite official primary sources (including gesetze-im-internet.de, make-it-in-germany.com, bamf.de, auswaertiges-amt.de, bundesnetzagentur.de, verbraucherzentrale.de, oesterreich.gv.at, and ch.ch) inside an explicit Sources & verification box on those civic and administrative guides showing when the facts were last checked.

3. Corrections & Updates

When municipal fees, tax thresholds, or German spelling recommendations change, we update the relevant guide and reflect the verification date transparently in the article header and sitemap. Readers can report corrections anytime via contact@reinlogic.com.
