This website

This website uses no cookies, no analytics or advertising tools and loads no content from third-party servers (system fonts only). However, when you visit it, our hosting provider processes the technical access data required for delivery and security; see “Hosting”.

If you change the language using the switch, your choice is stored locally in your browser (localStorage). It is used only to display the site in your chosen language and is not transmitted to us.

Hosting

The website is hosted by Unaxus (unaxus.de), acting as a service provider on our behalf. When you visit, technical access data (in particular IP address, date and time, page requested, browser and system information) is processed in server log files. The purpose is secure and stable operation of the website; the legal basis is Art. 6(1)(f) GDPR. The type and duration of storage are governed by the Unaxus privacy information: unaxus.de/agb. We do not analyse this data.

The app “Blutdruck-Tracker”: local use

The app stores all data (readings, photos of the device display, set-up devices) locally on your device. It has no account, no ads, no data collection, no third-party SDKs and does not open network connections by itself. There is no cloud sync of its own and no connection to Apple Health. We receive no data from you in this way.

Name and date of birth (optional): In Settings you can enter your name and date of birth for the PDF export. This information is also stored only locally on your device and appears only in PDFs that you create and share yourself.

Backups: App data may be part of the iOS device backup you have set up (e.g. iCloud backup or computer). This depends on your system settings and is processed by Apple, not by us.

Deletion: You can delete individual readings and set-up devices in the app. Deleting the app removes its local data, including set-up devices, from your device.

Camera and photos: The camera is used only for photos of the device display. Photos are selected through the iOS system picker; the app receives only the image you choose.

Sharing and PDF export

PDF exports leave the device only when you share them yourself via the share sheet. You choose the recipient and the transmission channel; they are responsible for any further processing.

Setting up a device

If your blood pressure monitor is not recognized automatically, you can set it up in the app. There are two ways:

1. Set it up yourself with the camera: you mark on a photo of the display where the values are and test until it works. This happens entirely on your device; no data is transmitted to us. The device you set up stays stored on your device until you delete it yourself.

2. Send photos of the device display to the developer: the app opens a prepared e-mail draft to development [at] trynogga [dot] com. It may contain a photo of the display, recognized and entered values, app version, iOS version, device model and app language. Before opening the draft, the app shows a notice; by sending the e-mail you give your consent; you see the full content before sending, and the app sends nothing automatically.

The photo and values may be health data. We process them only if you send them, and solely to support your device in the app. The legal basis is your explicit consent (Art. 6(1)(a), Art. 9(2)(a) GDPR). It is voluntary; without it the app remains fully usable, and manual entry works with any device. You can withdraw it at any time with effect for the future by e-mail.

The data received by e-mail (photo, values, technical details, your e-mail address) is not passed on and is deleted within three months of receipt, including attachments and mailbox. The device support we create on that basis (layout and structure of the display, manufacturer and model) contains no readings and no personal data. It becomes a permanent part of the app and is available to all users; it is not deleted.

Contact form and support requests

If you write to us via the contact form or by e-mail, we process the data you provide (name, e-mail address, message) to answer your request. The form is processed by a script on the website’s server that forwards the message to us by e-mail; nothing is stored in a database. The legal basis is Art. 6(1)(b) or (f) GDPR and your consent (Art. 6(1)(a)). We delete the request once it is closed, at the latest after three months, unless statutory retention duties apply. Please do not send us health data.

Your rights

You have the right of access, rectification, erasure, restriction of processing and data portability under the GDPR. Where we process data based on legitimate interests, you may object on grounds relating to your particular situation. You can withdraw any consent at any time; the lawfulness of processing before withdrawal is not affected. You also have the right to lodge a complaint with a supervisory authority (competent: the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia).
