Privacy Policy
Last updated: September 14, 2026
This privacy policy applies exclusively to the iOS app Wortivo – not to the Krümelmarkt platform that technically hosts this page.
1. Data controller
The controller responsible for data processing under the General Data Protection Regulation (GDPR) is:
Sebastian UeberwolfKonstantinstraße 274
41238 Mönchengladbach
Deutschland
Telefon: +49 2166 9978839
E-Mail: info@krümelmarkt.de
2. No user account
Wortivo requires no registration and no user account. Using the app collects neither your name, nor an email address, nor a password.
3. Local storage of vocabulary and learning progress
Your collections, vocabulary, and learning progress (e.g. box assignment, due repetitions) are stored exclusively on your device. None of it is transmitted to the operator’s servers.
4. Camera and photo access
Wortivo only requests access to the camera or photo library when you yourself start a photo import to scan a vocabulary page. Without that user-initiated action, the app does not access your camera or photos.
5. Text recognition (OCR)
Recognizing word pairs in a photo uses Apple’s Vision framework entirely on your device. The photo and the recognized text are never sent to the operator’s servers or to any third party. After recognition, you can review and correct every row before saving.
6. Voice input
When you dictate vocabulary, Wortivo uses Apple’s speech recognition on-deviceby default – your audio never leaves your device. If no offline speech model is installed for the selected language, Wortivo offers to process that one recording online via Apple’s speech recognition service instead. If you choose to do so, Apple processes that audio under its own privacy policy – Wortivo itself never receives or stores that audio.
7. In-app subscriptions and payment processing
Wortivo Pro is an optional subscription purchased exclusively through Apple’s in-app purchase system (StoreKit). Payment processing is handled entirely by Apple; Wortivo and its operator never receive or process any payment or card data. Billing, management and cancellation happen through your Apple account (Settings → Apple Account → Subscriptions).
8. No advertising tracking, no analytics SDKs
Wortivo uses no advertising networks, no personalized advertising, and no third-party analytics or tracking services. No user profiles are created.
9. Required device permissions
Wortivo requests the following permissions, each only when needed:
- Camera – to scan vocabulary pages.
- Photo library – to scan vocabulary pages from selected photos.
- Microphone – to dictate vocabulary.
- Speech recognition – to convert dictated vocabulary into text.
If you decline a permission, the remaining features of Wortivo (e.g. manual entry) remain fully usable.
10. Deleting local data
You can delete individual vocabulary entries, entire collections, or your learning progress at any time directly in Wortivo. Uninstalling Wortivo removes all of the app’s locally stored data from your device.
11. Your rights
Because Wortivo does not transmit personal data to the operator, there is typically no stored user data at the operator to report on. Regardless, under the GDPR you have the right to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and objection (Art. 21). For questions, reach us at info@krümelmarkt.de. You also have the right to lodge a complaint with a data protection supervisory authority.
12. Minimum age
Wortivo is designed for a broad audience of vocabulary learners. Since no personal data is collected, using the app itself carries no particular data-protection risk for minors.
13. Further information from Apple
Since Wortivo relies on Apple’s own services for voice input and in-app purchases, you can find additional information directly from Apple:
