Data collection

Providing this website requires the processing of personal data, such as your IP address. This processing is necessary in order to retrieve the content displayed on this website (including its functions) and for reasons of IT security measures.

The processing of your personal data for the provision of this website is carried out on the basis of our overriding legitimate interest (Art. 6(1)(f) GDPR). In order to provide this website, it is technically necessary for us to process certain personal data (e.g. the IP address).

As part of the required balancing of interests, we have weighed your interest in confidentiality against our interests in providing this website. Your interest in confidentiality is outweighed in each case. Otherwise, we would not be able to provide you with this website.

We use service providers to provide our website. For this purpose, we transmit personal data to these service providers. These service providers are contractually obliged by us to exercise the same care in handling personal data as we do ourselves.

Mailing list

On our website you can enter your email address to join our mailing list and receive news and announcements about our software. For this purpose we process your email address, the language setting used at the time of signup, and the time of signup.

The legal basis for this processing is your consent (Art. 6(1)(a) GDPR). Providing your email address is voluntary; without it we cannot send you any news.

You can withdraw your consent at any time with effect for the future. The unsubscribe link at the end of every email is sufficient, as is an informal message to contact@dihedron.net. The lawfulness of the processing carried out up to the withdrawal remains unaffected. Following your withdrawal we delete your email address from the mailing list.

These emails are sent via Resend, Inc. as a processor; see the section “Data transfers to third countries”.

Software update check

On startup, the “Blick” and “Zeiger” programs each make a single request to our server (blickeditor.com) to check whether a newer version is available. For technical reasons this transmits your IP address, without which no response could be delivered. The IP address is processed solely to answer the request and is neither stored nor linked to any other data. The software transmits no further data, in particular no usage data and no information about your system.

The legal basis for this processing is our legitimate interest (Art. 6(1)(f) GDPR) in being able to inform you about available updates, in particular security updates.

Zeiger’s access to the Apple Photos library

On macOS, the “Zeiger” software can show your Photos library if you allow access in System Settings. The photos are shown only locally on your device. Zeiger transmits neither photos nor information about your library to us or to third parties. If photos are stored only in iCloud, macOS downloads them through Apple’s Photos interface; Apple carries out this processing under its own privacy policy. You can withdraw access at any time in System Settings under “Privacy & Security > Photos”.

Embedded YouTube videos

On our home page we embed videos from the YouTube platform. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. We use YouTube’s privacy-enhanced mode (youtube-nocookie.com).

When you visit our website, only a preview image is shown at first. Our server retrieves this preview image and the details of the current video from YouTube itself at regular intervals; no visitor data is transmitted in the process. Loading the page therefore transmits no data to YouTube.

The video is loaded from YouTube only when you click the preview image. YouTube then receives in particular your IP address, the address of our website, and technical information about your browser and device. YouTube may also store or read information in your browser (e.g. cookies or local storage). If you are logged in to a Google account, YouTube can associate the playback with that account.

The legal basis is your consent, which you give by clicking the preview image (Art. 6(1)(a) GDPR, Section 25(1) TDDDG). We do not store this decision; on every page visit the video is loaded only after a new click. You can withdraw your consent at any time with effect for the future by stopping playback and deleting the information stored by YouTube in your browser settings.

Once the video has loaded, Google processes the data under its own responsibility. Google also processes data in the USA; Google LLC is certified under the EU-US Data Privacy Framework. For more information, see Google’s privacy policy: policies.google.com/privacy.

Beyond that, we do not transfer your personal data to countries outside the EU or the EEA or to international organisations, unless expressly stated otherwise in this privacy notice.
