2. Data Processing in Our App

2.1. Collection, Processing and Use of Personal Data

The following personal data may be processed in the course of using our apps:

• Contact data of you and your customers
  (name, first name, address, telephone number, fax number, mobile number, email address)

• Images selected by you

• Your location data

The apps offer the possibility to record the measurement data measured by our measuring instrument, to process it for the creation of a report, to create the report itself and to integrate the measured values and other data into the report. All data retrieved from your end device and its use serve exclusively for the creation of reports. The legal basis is Art. 6(1)(b) GDPR.

The Saveris Installation App guides you through the installation of Testo Saveris devices and also offers Testo employees the possibility to create an acceptance report. In this report, the name, email address and signature of the Testo employee as well as the name, address of the installation site and email addresses of the customer are processed. The legal basis is Art. 6(1)(b) GDPR.

2.2. Contact

You have various ways of contacting us, including the contact form on our website, the telephone hotline and contact via email. In this context, we process data exclusively for the purpose of communicating with you. The legal basis is Art. 6(1)(b) GDPR. The data collected by us when using the contact form will be automatically deleted after your request has been fully processed, unless we still need your request to fulfil contractual or legal obligations (see section "Retention Period").

2.3. Integration of Your Contacts and Images into the Report
(does not apply to Saveris Installation App)

You have the option to include your contact data and images in the report. In doing so, the apps actively access your personal data (name, first name, address) from your contact list or images from your photo gallery after you have selected the contacts in advance. The legal basis is Art. 6(1)(b) GDPR.

All data/photos selected by you and inserted into the report are simply copied from the storage location of your end device into the report.

2.4. Use of Your Location Data
(does not apply to Saveris Installation App)

For the communication of our measuring instrument with measuring probes/other devices via Bluetooth, it may be necessary to collect your location data. You must therefore activate the location service on your device. This access to your location data is required exclusively for the functionality of Bluetooth communication. We will neither use your location data for any other purpose nor store it. The legal basis is Art. 6(1)(b) GDPR.

2.5 Data Processing in the Event of App Crashes

Description and scope
To improve the stability and reliability of our apps, we depend on crash reports from our users. Such crash reports contain anonymous technical information that helps us to reproduce the crash and understand its cause so that we can fix it in one of our next app versions.

Your IP address is processed for the transmission of this data. Your IP address is not stored or processed for any other purposes.

Purpose
The crash information is processed to analyse the crashes in order to improve the stability and reliability of the apps. The processing of your IP address serves the transmission of crash reports.

Legal basis
The legal basis for the processing of the data transmitted in the course of transmitting crash reports is Art. 6(1)(f) GDPR. Our legitimate interest is to improve the stability and reliability of the apps, to prevent crashes and thus to improve usability.

Right to object
You can object to the processing of crash information at any time by deactivating the transmission in the app settings.

2.6 Update Information

Description and scope
The end user is notified within the app, via push notification or email, about new updates, such as firmware updates for Testo devices.

Purpose
Sending information about (firmware) updates for the registered devices via in-app messaging or push notifications.

The legal basis is Art. 6(1)(f) GDPR. Our legitimate interest lies in product maintenance by providing (firmware) updates, which can fix software errors and provide new functions.

Right to object
You can object to update notifications at any time by deactivating them in the app settings.

2.7 Sending of Marketing Messages & Customer Satisfaction and Product Improvement Surveys

Description and scope
The end user is sent marketing information within the app via in-app messaging or outside the app via push notification or email about accessories for registered products, as well as further Testo products and services, and surveys on customer satisfaction and product improvement. The information may be based on the way the user uses functions in the app as well as location and language settings.

2.8 Analysis of Usage Behaviour

Certain actions performed by the user are logged and transmitted to give Testo the opportunity to develop a better understanding of how end users use the individual functions. Examples of this include: generating a report as CSV or PDF, using a specific measurement programme (volume flow, tightness test, ...) or individual button clicks. No personal data that you enter into the app is collected in this process.

Purpose
Improvement of the user experience.

Personal data
Usage behaviour, all measuring devices you have ever connected to the testo Smart app, unique identifier (ID)

Deletion of your data
You can have the data deleted at any time by completing and submitting the form at https://www.testo.com/en/contact/appsupport In the form, you must provide an ID with which we can identify your data record for deletion. This information is required because we do not link the analysis data with other data and therefore cannot identify you in any other way. You can find the ID in the testo Smart App under "Help and Information" > "Device Information".

3. Synchronisation with testo Smart Connect

Description and scope of processing
The testo Smart App offers you the possibility to connect to the cloud software testo Smart Connect, provided you actively use this function. In this context, you can create a user account or use an existing account.

In the course of synchronisation, the following data is processed in particular: account data such as username and email address, a unique user identifier (ID)

Information about your company and the persons acting on its behalf, data on the measuring instruments paired with the mobile device, administrative and measurement data, including data that you collect in connection with your own customers.

If you process personal data of your customers using the app and the connected measuring instruments, this is done under your own data protection responsibility. In this case, you are obliged to reflect the processing in your own privacy notice and, where necessary, to conclude a data processing agreement with Testo in accordance with Art. 28 GDPR.

Further information on data processing in testo Smart Connect can be found in the corresponding privacy policy.

Purpose of processing

The processing is carried out to provide the synchronisation function between the app and testo Smart Connect. This includes in particular:

• Management and organisation of the measuring instruments used

• Storage and synchronisation of measurement and administrative data

• Enabling the shared use of this data within your company

Legal basis
The processing is carried out on the basis of Art. 6(1)(b) GDPR, insofar as it is necessary for the provision of the synchronisation function.

Deactivation of synchronisation
You can end the synchronisation at any time by disconnecting the testo Smart App from testo Smart Connect. From this point on, no further data transfer will take place.

Retention period and deletion
You have the option at any time to delete synchronised data in testo Smart Connect and to close your user account.

4. Disclosure of Data

Use of Sentry (Error Analysis)

Description and purpose of processing
To ensure the stability and security of the app, we use the Sentry service of Functional Software, Inc., USA. Sentry is used to analyse technical errors and crashes in order to improve the functionality of the app.

In the course of error analysis, technical information is processed, in particular:

• Information about the device and operating system

• Time of the error

• Technical log data on the crash sequence

It is not the purpose of the processing to identify you as a user.

Data Protection Measures (Relay Server)
To protect your personal data, we use a so-called relay server. This acts as an upstream instance and ensures that in particular no IP address or other directly identifying data is transmitted to Sentry in the USA.

The relay server is operated within the European Union by Amazon Web Services EMEA SARL, Luxembourg. This architecture considerably reduces the risk of personal identification.

Third-country transfer
A transfer of data to the USA cannot be completely excluded. However, this is carried out exclusively in anonymised or pseudonymised form. In addition, appropriate safeguards pursuant to Art. 46 GDPR are used (in particular standard contractual clauses).

Legal basis
The processing is carried out on the basis of Art. 6(1)(f) GDPR. Our legitimate interest lies in ensuring the technical stability, security and continuous improvement of the app.

5. Retention Period

In principle, we store personal data only for as long as is necessary to fulfil the contractual or legal obligations for which we collected the data. After that, we delete the data immediately, unless we still need the data until the expiry of the statutory limitation period for evidentiary purposes for civil law claims or due to statutory retention obligations.

Your photos and contact data in the reports are not stored.

In addition, our apps can also write to your SD card/storage location on request. This allows you to save your actively selected data (measured values, reports, images, other data) on the SD card/in the storage location.

The IP address is only processed for data transmission. No further processing, and in particular no storage, takes place.
