We use Umami, a privacy-friendly, self-hosted web analytics tool. Umami collects anonymous, aggregated usage statistics only (page views, time on page, referrer, device type). No cookies are set, no IP addresses are stored, and no cross-device tracking takes place. Identification of individual visitors is not possible.

4. Yuzen CRM iOS App

The Yuzen CRM iOS app processes personal data as follows:

Contact data: The app accesses the native iPhone address book (Contacts.framework). Contact data is not transmitted to our servers and remains exclusively on the user's device.

CRM data (leads, activities, pipeline): Leads, activities, pipeline settings, and email templates are synchronized with our PocketBase backend and stored on German servers (Hetzner). Transmission is encrypted (HTTPS).

AI features:

No third-party AI APIs are used. All AI-related cloud calls go exclusively to our own backend (yuzu.chat). The legal basis is Art. 6 (1)(b) GDPR (performance of a contract).

App analytics: The app uses Aptabase, a privacy-friendly, self-hosted analytics tool. Our Aptabase instance runs on our own infrastructure (Hetzner, Germany). Only anonymous, aggregated usage statistics are collected (e.g. app launches, features used). No personal data, no device IDs, and no cross-device tracking are recorded. The legal basis is Art. 6 (1)(f) GDPR.

Email sending: Emails are sent through the native iPhone Mail app (MessageUI). We have no access to email content or send history.

User account: On registration we store your email address and a hashed password. The legal basis is Art. 6 (1)(b) GDPR (performance of a contract).

7. User Obligations

The user agrees to use the app only for lawful purposes and not to store any content that violates applicable law. The user is responsible for the security of their login credentials.

8. Limitation of Liability

The Provider's liability is limited to intent and gross negligence. In cases of slight negligence, the Provider is only liable for a breach of material contractual obligations (cardinal duties), limited to the foreseeable damage typical of the contract. This does not apply to damages resulting from injury to life, body, or health.
