How we work

German users need an app with consent screens that meet GDPR and the BDSG before they reach the second screen. The app also needs an AVV in place with every analytics, crash-reporting or push-notification vendor that touches personal data, and from June 2025 it needs accessibility that meets the BFSG for covered app categories such as banking.

We design onboarding, permission requests and payment flows around those specifics from the start, then deliver remotely with test builds shared regularly and reviews scheduled inside CET/CEST hours.

Market

What Germany buyers expect from this work

Every third-party SDK that touches personal data needs an AVV behind it
Analytics, crash-reporting and push-notification vendors typically process personal data on your behalf, which means a data processing agreement needs to be in place with each one under GDPR Article 28. We map which SDKs the app uses and confirm an AVV exists or is signed before the app ships.
German-language onboarding is expected, not optional, for a consumer app
German consumer apps are generally expected to onboard users in German, with English as a secondary option where relevant. We build the localization layer around that expectation from the first release rather than shipping English-first and translating later.
Payment integration means SEPA, PayPal and Klarna, not just cards
German shoppers commonly reach for SEPA direct debit, PayPal or Klarna before a credit card. We integrate the combination that matches your product and processor rather than defaulting to a card-only checkout that leaves out the options German customers expect.
BFSG accessibility reaches banking and other covered apps from June 2025
Where an app falls under the BFSG's scope, typically banking and other covered digital services, we build to WCAG-aligned mobile accessibility patterns as part of the UI work rather than a post-launch remediation project.
A commercial app carries the same Impressum expectation as a website
German legal guidance treats an app offered commercially the same as a website for Impressum purposes under the Digitale-Dienste-Gesetz, which means operator identity and contact details need to be reachable from within the app, not just from a linked website. We add an accessible legal or about screen with the required disclosures as part of the build rather than assuming a store-listing link satisfies the requirement.
In-app tracking SDKs need TDDDG consent before they initialize, not just Apple's prompt
Apple's App Tracking Transparency prompt covers cross-app tracking on iOS, but the TDDDG's consent requirement is broader, covering analytics and similar tracking technology on both iOS and Android. We gate SDK initialization behind that consent rather than relying on the ATT prompt alone to cover German requirements.

Compliance we plan for

GDPR and the BDSG for personal data collected or processed by the app
AVV in place with analytics, crash-reporting and notification vendors handling personal data
European Accessibility Act / BFSG for covered app categories from June 2025
TDDDG-aligned consent for tracking technology used within the app

How the engagement runs

We map which third-party SDKs the app depends on during discovery and confirm AVV coverage for each one that processes personal data. Development runs in sprints with regular test builds, and reviews are scheduled inside CET/CEST hours.

Invoicing is in EUR against delivery milestones, settled by SEPA transfer, and the codebase, store listings and signing credentials stay under your control throughout.

FAQ

Frequently asked questions

Do we need a data processing agreement with our app's analytics provider?

Generally yes, if the analytics provider processes personal data from German or EU users on your behalf, GDPR Article 28 requires an Auftragsverarbeitungsvertrag with them. We map which SDKs in the app touch personal data and confirm AVV coverage exists before launch.

Should our app onboard users in German by default?

For a consumer app targeting the German market, yes, German-first onboarding with English as a secondary option is the expectation. We build the localization layer around that from the first release.

Can you integrate Klarna and SEPA direct debit into our app's checkout?

Yes. We integrate the combination of SEPA direct debit, PayPal, Klarna and card payments that fits your product and payment processor, since German customers commonly expect at least one of these alongside cards.

Does our banking app need to meet BFSG accessibility requirements?

If it falls under the BFSG's scope, which includes banking apps, yes, from June 2025. We build to WCAG-aligned mobile accessibility patterns as part of the UI implementation so the requirement is met at launch.

How do you handle App Store and Play Store submission for a German launch?

We handle store listing content in German and English where relevant, along with privacy-label disclosures that accurately reflect the app's data collection and any AVV-covered third-party processing.

Does our app need an Impressum, or is that only for websites?

German legal guidance treats a commercial app the same as a website for Impressum purposes, so operator identity and contact details need to be reachable from within the app itself. We add an accessible legal or about screen with the required disclosures as part of the build.

Does Apple's App Tracking Transparency prompt cover our German consent obligations?

Not entirely. ATT covers cross-app tracking on iOS specifically, while the TDDDG's consent requirement is broader and applies to analytics and similar tracking technology on both iOS and Android. We gate SDK initialization behind TDDDG-aligned consent rather than relying on the ATT prompt alone.

Do in-app subscription prices need to show German VAT?

Yes, whether billing runs through the App Store, Play Store or a direct processor, the displayed price and receipt need to reflect VAT, currently 19% standard rate with a 7% reduced rate for certain categories. We confirm which billing path applies and build the price and receipt display to match rather than assuming the platform handles it correctly by default.
