✦Grammar Breakdown
KeineGebühr,wennduinnerhalbdesZeitfenstersänderst.
Negation with kein-
‘Keine’ is the feminine form of ‘kein’ used to negate a feminine noun like ‘Gebühr’.
Noun gender
‘Gebühr’ is feminine, so the article and adjective take the ‘-e’ ending in the accusative.
Subordinate clause with wenn
‘wenn’ introduces a conditional clause; the verb moves to the end (‘änderst’).
Genitive after innerhalb
‘innerhalb’ governs the genitive case, therefore ‘des Zeitfensters’ (neuter, genitive).
Second‑person singular verb
‘ändern’ conjugated for ‘du’ is ‘änderst’ – note the umlaut and the -st ending.

Keinen Gebühr, wenn du innerhalb des Zeitfensters änderst.
‘Gebühr’ is feminine; the correct negation is ‘keine’, not the masculine ‘keinen’.
innerhalb des Zeitfenster änderst
‘innerhalb’ requires the genitive case, so the noun must take the -s ending: ‘Zeitfensters’.
wenn du innerhalb des Zeitfensters ändern
In a ‘du’ clause the verb must be conjugated: ‘änderst’.

Cultural Tip
In German business communication the choice of ‘du’ vs. ‘Sie’ signals the level of formality. ‘Du’ is informal and common in apps, startups, and among younger customers. If you’re addressing a formal audience, switch to ‘Sie’: ‘Keine Gebühr, wenn Sie innerhalb des Zeitfensters ändern.’ Also, German contracts often specify exact time windows, so the phrase is a standard reassurance.
