All AI processing is performed on servers located within the European Union. Your brand data and content inputs are processed by AI models solely to deliver the Service features you request. We do not use your content to train general-purpose AI models.

2.3 Service improvement and analytics

We may use your personal information to analyze your usage of the Service, improve the Service, improve the rest of our business, help us understand user activity on the Service, including which pages are most and least visited and how visitors move around the Service, as well as user interactions with our emails, and to develop new products and services.

We use Google Analytics for this purpose. You can learn more about Google Analytics and how to prevent the use of Google Analytics relating to your use of our sites here: https://tools.google.com/dlpage/gaoptout.

2.4 Research and development

We may use your personal information for research and development purposes, including to analyze and improve the Service and our business and to develop new products and services. As part of these activities, we may create aggregated, de-identified and/or anonymized data from personal information we collect. We may use this aggregated, de-identified and/or anonymized data and share it with third parties for our lawful business purposes, including to analyze and improve the Service and promote our business. We will not attempt to reidentify any such data.

2.5 Marketing and advertising

We, our service providers and our third-party advertising partners may collect and use your personal information for marketing and advertising purposes:

• Direct marketing. We may send you direct marketing communications and may personalize these messages based on your needs and interests. You may opt-out of our marketing communications as described in the Your Choices section below.
• Interest-based advertising. Our third-party advertising partners may use cookies and similar technologies to collect information about your interaction with the Service, our communications and other online services over time, and use that information to serve online ads that they think will interest you. This is called interest-based advertising. We may also share information about our users with these companies to facilitate interest-based advertising to those or similar users on other online platforms. You can learn more about your choices for limiting interest-based advertising in the Your Choices section of our Cookie Policy.

2.6 Compliance and protection

We may use your personal information to:

• Enforce the Terms of Service that govern the Service.
• Prevent, identify, investigate and deter fraudulent, harmful, unauthorized, unethical or illegal activity, including cyberattacks and identity theft.

2.7 With your consent

In some cases, we may specifically ask for your consent to collect, use or share your personal information, such as when required by law.

2.8 Retention

We generally retain personal information to fulfill the purposes for which we collected it, including for the purposes of satisfying any legal, accounting, or reporting requirements, to establish or defend legal claims, or for fraud prevention purposes. To determine the appropriate retention period for personal information, we may consider factors such as the amount, nature, and sensitivity of the personal information, the potential risk of harm from unauthorized use or disclosure of your personal information, the purposes for which we process your personal information and whether we can achieve those purposes through other means, and the applicable legal requirements.

Specific retention periods:

• Active account data: retained for as long as the account is active.
• Personal data after account deletion: deleted within 30 days.
• Billing and financial records: 10 years (as required by German commercial law, HGB Section 257, AO Section 147).
• Application and activity logs: 90 days.
• AI processing debug logs: 30 days.
• Backup archives: 90 days.

When we no longer require the personal information we have collected about you, we may either delete it or anonymize it. If this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible. If we anonymize your personal information (so that it can no longer be associated with you), we may use this information indefinitely without further notice to you.
