No personal data retained.
Last updated: October 21, 2026
Privacy Overview
Checklist Pro is designed without user accounts or server-side personal profiles. Wissing Holding does not collect or retain personal user data through normal use of the app.
Information Collection
Checklist Pro does not require registration, sign-in, passwords, names, email addresses, phone numbers, or profile creation. We do not operate a personal-data account database for normal app use.
App Data & Local Storage
Lists, tasks, notes, progress information, preferences and related app content are intended to remain on the user's device. Wissing Holding does not receive or store this content on a company server through normal app use.
Website Data
This static website has no accounts, forms, user profiles or application database. Standard infrastructure-level request logs may be processed by the hosting provider according to its own operational and legal requirements.
Third-Party Services
The website links to Google Play. When you follow that link, Google's own privacy terms apply.
Data Retention
No personal user data is retained by Wissing Holding through normal use of Checklist Pro. We do not maintain user accounts, cloud profiles, or a server-side database containing your task lists, notes, progress information or app preferences.
If you voluntarily contact us by email, that correspondence may remain in our email system only as long as reasonably necessary for communication, support, legal compliance or legitimate administrative purposes.
Data Deletion
Because Wissing Holding does not maintain a server-side personal profile for Checklist Pro, there is normally no account data on our systems that requires deletion.
App content stored locally can be removed using the app's controls where available or by removing the app data from your device. If you voluntarily contact us by email, you may request deletion of personal information contained in that correspondence where legally applicable by emailing support@wissingholding.site.
Children
Checklist Pro is not designed to collect personal information from children, and Wissing Holding does not knowingly operate a user-profile database for children or adults through normal use of the app.
Policy Changes
This policy may be updated if the product, website or legal requirements change. The current version will be published here with an updated date.
