OpenZen
Change log
On 7 September 2026, product descriptions, platform details, data processing information and language versions were revised. Earlier blanket claims that all five apps used the same proprietary AI were incorrect and have been replaced with version-specific information.
Availability
LifeZen, HelpZen and MedZen are publicly available for iOS and Android. DocZen 1.0 and JobZen 1.2 are available in the German App Store. DocZen 1.1 is prepared; JobZen Android has been submitted for a closed test.
| App | Availability | Data processing |
|---|---|---|
| LifeZen | iOS 1.1 · App Store · Publicly available | Android 1.0.3 · Google Play · Publicly available | From iOS 1.1 and Android 1.0.3, LifeZen sends the selected photo, language and, where applicable, location information over an encrypted connection to OpenZen AI 2B on self-managed infrastructure in Germany. Older versions use an external AI service. No account is required. |
| HelpZen | iOS 1.1 · App Store · Publicly available | Android 1.2.0 · Google Play · Publicly available | Search and distance calculations run in a directory on your device. Updates come from OpenZen over HTTPS. iOS uses Apple MapKit; Android uses MapLibre with OpenFreeMap. Map services may receive connection data and the requested map area. Search does not call generative AI. |
| MedZen | iOS 1.4 · App Store · Publicly available | Android 1.1.2 · Google Play · Publicly available | MedZen searches an on-device database and orders results by distance. Updates come from OpenZen over HTTPS. iOS uses Apple MapKit and may offer system translation; Android uses OpenStreetMap-based maps. Location and map services may process connection data. Search and sorting do not need generative AI. |
| DocZen | iOS 1.0 · App Store · Publicly available DocZen 1.1 for iOS and Android is prepared but has not been publicly released. | Published iOS version 1.0 sends selected document content to an external AI service. Processing exclusively in Germany does not apply to that version. Prepared version 1.1 recognises text on the device using Apple Vision or Android ML Kit and sends recognised text, target language and page number over an encrypted connection to OpenZen AI 2B in Germany. Images and PDFs stay on the device in this new architecture. |
| JobZen | iOS 1.2 · App Store · Publicly available JobZen Android 1.2.0 has been submitted to Google for a closed test. Approval is pending. | Search sends the postal code or coordinates, radius, selected KldB codes, employment and language filters, and app language to the JobZen server in Germany. CVs are not processed and people are not assessed by AI. Favourites and settings stay local. iOS uses Apple system features for optional translation; Android uses ML Kit. |
Outstanding checks
Outstanding work includes full testing on real devices, language quality, accessibility, continued directory freshness and complete documentation of retention periods and provider agreements. Checking backups technically does not replace a full failover test.
