How do I cancel?
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
Only your company's owner can cancel, under Einstellungen (settings) in the Firma & Tarif (company & plan) tab, with Abo kündigen (cancel subscription). The cancellation takes effect at the end of the current month, or at the end of the free trial if you're in one. Until then you keep working as usual and can withdraw the cancellation. Cancelling covers your whole company with all its OTTO accounts.
How it works
The owner is whoever created the company in MargenOptimierer, or whoever that person transferred ownership to. The process has four to six pages, and nothing is cancelled until the last click.
- Under Einstellungen, in the Firma & Tarif tab, click Abo kündigen at the bottom of the Zahlung (payment) card.
- The first pages show what you've achieved or set up with MargenOptimierer and what you lose by cancelling. On each one, click Weiter zur Kündigung (continue to cancellation).
- On the Warum möchtest du kündigen? (why do you want to cancel?) page, choose your reason, write at least 30 characters in the field below it and click Weiter zur Kündigung.
- If the next page offers you a free month and you don't want it, click Weiter zur Kündigung there as well.
- On the last page, type your company's name and tick Ich habe verstanden. (i understand.)
- Click Vorteile aufgeben und kündigen (give up benefits and cancel). If you'd rather stay, click Doch bleiben (stay after all) instead.
Example: Cancelling on 27 October 2026
If you cancel on 27 October 2026, your subscription ends on 31 October 2026. The last invoice, for October, comes on 16 November 2026. If you're still in the free trial on 27 October 2026 and it ends on 5 November 2026, your subscription ends on 5 November 2026 and no invoice comes.
What applies after you cancel
Free month or joint setup
If none of your OTTO accounts has had a free month yet, a page offers you one. If you claim it with Gratismonat sichern (claim free month), nothing is cancelled, and on your next invoice you pay neither base price nor ad share. If you're still in the free trial and it ends before the last day of the month, you also pay nothing for the remaining days of that month and the whole month after it. If your numbers don't show any improvement yet or you choose „Zu kompliziert“ (too complicated) as your reason, MargenOptimierer also offers to set up your account together with you for 30 minutes, free of charge. If you click Gemeinsam einrichten, 30 Minuten (set up together, 30 minutes), nothing is cancelled, and MargenOptimierer contacts you by email.
What happens to your data
The last page says „Deine Daten werden unwiderruflich gelöscht.“ (your data will be irrevocably deleted.) When your subscription ends, your access ends too, and you no longer see any numbers in the app.
Withdrawing your cancellation
Until your subscription ends, a notice with the date appears at the top of every page in the app. Click Kündigung zurücknehmen (withdraw cancellation) there, and your subscription continues as before. An admin can withdraw it too, not only the owner.
