MarketingHub is an AI-powered content generation platform currently in beta/MVP phase. MarketingHub is accessible globally via the internet. We may offer the service in multiple jurisdictions subject to applicable laws. Our service processes user inputs to generate marketing content using third-party AI providers.
Account Information: Email address, name, company name (if provided), password (encrypted).
Billing Information: Payment details are processed by our payment provider Stripe. We store billing address and transaction history but not full credit card numbers.
Usage Data: Content inputs and outputs, usage metrics, feature interactions, error logs.
Technical Data: IP address, browser type, device information, session data stored via localStorage.
Communications: Support requests, feedback, email correspondence.
We work with the following subprocessors:
AI Training Representations: Our AI providers represent in their respective policies that inputs submitted via API are not used to train their models. We cannot provide absolute guarantees regarding third-party practices. For details, please review:
We will provide 30 days notice of material changes to our list of subprocessors via email or in-app notification.
We use localStorage (browser-based storage) for authentication and session management. This technical storage is essential for the service to function.
We do not currently use third-party advertising or tracking cookies. If we introduce optional analytics or marketing cookies in the future, we will provide advance notice and, where required by applicable law, request your consent before implementing such cookies.
We retain your data for as long as your account is active or as needed to provide services. After account deletion, we will delete or anonymize your data within 90 days, except where longer retention is required by law (e.g., German tax law requires 10 years retention for billing records).
We implement reasonable technical and organizational measures to protect your data, including:
No security system is impenetrable. While we strive to protect your data, we cannot guarantee absolute security.
In the event of a data breach affecting your personal information, we will notify you and relevant authorities as required by applicable law, typically within 72 hours of discovery.
You may update your account information at any time through your account settings. You may delete your account, which will initiate data deletion as described in Section 7.
As we operate from Germany and use global service providers, your data may be processed in various locations, including the United States. Where required, we rely on appropriate safeguards such as Standard Contractual Clauses for such transfers.
MarketingHub is not intended for users under 18 years of age. We do not knowingly collect information from individuals under 18.
We will notify you of material changes to this Privacy Policy via email or prominent in-app notice at least 30 days before the changes take effect. Continued use after changes constitutes acceptance.
This addendum applies if you are located in the European Economic Area, Switzerland, or the United Kingdom.
We process your personal data under the following legal bases (GDPR Art. 6):
You have the right to:
Exercising Your Rights: Email info@nextgenwebs.de with your request. We will respond within 30 days.
While we honor deletion requests, German tax law (AO Section 147, HGB Section 257) requires us to retain billing and accounting records for 10 years.
