01 / Overview

Privacy Policy

This Privacy Policy applies to the Knowledge Log mobile application and related services operated by Hübner GmbH (the “Service Provider”).

Core privacy principle: Knowledge Log does not collect, log, or store personal information through normal use of the Application, and registration is not required.

This Privacy Policy is effective as of 3 September 2026.

02 / Information

What information does the Application obtain?

The Application does not collect, log, or store personal information when you download and use it. Registration is not required.

If the Application is used with an active internet connection, technical protocol data such as an ephemeral IP address may be transmitted as part of ordinary network connectivity. Hübner does not retain this information or use it for tracking.

03 / Location

Precise location information

Knowledge Log does not collect precise real-time location information from your device.

04 / Third Parties

Do third parties receive information?

Because the Application does not collect personal information through normal use, Hübner does not share such information with third parties.

05 / Data Retention

Data Retention

Hübner does not retain personal data from normal use of Knowledge Log on its servers.

Knowledge Log does not require user accounts, does not create server-side user profiles, and does not keep a server-side history of ordinary in-app activity.

Facts, optional notes, categories, favorites, streak history, active learning days, progress statistics, activity history, and related preferences stored locally on your device remain under your control and are not retained by Hübner as personal data on its servers.

If you voluntarily contact Hübner outside normal app use, for example by email, information you provide may be retained only as needed to respond to your request, comply with applicable legal obligations, resolve disputes, or protect legitimate business interests.

06 / Data Deletion

Data Deletion

There is no Hübner account or server-side personal-data profile to delete for ordinary use of Knowledge Log.

Where Knowledge Log stores facts, notes, categories, favorites, streak history, activity history, statistics, or similar information locally on your device, you can remove that information using controls available in the Application, by clearing the Application’s local storage through your device settings, or by uninstalling the Application.

If you voluntarily provided personal information to Hübner outside normal app use, such as by sending an email, you may request deletion by contacting support@hubner.ink. Requests will be handled in accordance with applicable law.

07 / Children

Children

The Application is not intended for children under 13 years of age, or such higher minimum age as required by applicable law. Hübner does not knowingly solicit personal data from children or market the Application to them.

08 / Security

Security

Because Knowledge Log does not collect personal data through normal use, the risk of exposure of such data through Hübner systems is limited. No technical system is completely secure, and reasonable safeguards are applied to systems and any information lawfully held.

09 / Data Breach

Data Breach Notification

If a security incident affects personal information that you voluntarily provided to Hübner, appropriate steps and notifications will be provided where required by applicable law.

10 / Changes

Changes to this Privacy Policy

Hübner may update this Privacy Policy from time to time. Material changes will be reflected by publishing an updated version with a revised effective date.

Previous versions may be requested by contacting Hübner.
