Privacy Policy Teena App

Last updated 26 November 2026

Thank you for your interest in our online services, including our Teena app. We take the protection of your data very seriously and want you to feel safe when using our online services.

There are laws and regulations that protect you and your data on the Internet. These are commonly referred to as data protection. The aim of data protection is to protect you from the risk of unauthorised persons knowing and using your data or passing it on without your express consent.

We comply with data protection laws such as the General Data Protection Regulation (abbreviated to GDPR) and the German Federal Data Protection Act (BDSG).

In the following section we explain which of your data we process, for what reason and in accordance with which legal provisions.

Minors

If you are under 18 it is very important for us that you inform your parents if you wish to use our online services. And if you are under 16, you will need your parents’ permission before you can use our online services. This can also be others with parental authority, such as grandparents or legal guardians.

Data Controller

As defined by the GDPR and other national privacy protection laws of the member states of the European Union and Switzerland, in regard to data collected by the Apps, the "Controller" is Valley Electronics AG, Wengistrasse 2, 8004 Zurich, Switzerland. Represented by the Director, Natalie Rechberg-Egly.

Contract

In order to fulfill the obligations arising from a contractual relationship with you, we process your personal data to the extent necessary for the performance of the subject matter of the contract.

Within this framework of the contractual relationship between you and us, health data such as your body temperature, menstruation, etc. may also be processed. For such processing, we need your explicit consent. By submitting this data, you are granting us that consent.

The data will be deleted at the latest after the termination of the contractual relationship or at any time at your request, provided that we do not have any retention obligations for that data (e.g., in the case of complaint or feedback).

You may opt out of the privacy policy at any time by deleting your account or deleting the App.

The basis for the data processing is the performance of a contract or of pre-contractual measures in connection with the processing of health data (Article 6(1)(b) GDPR in conjunction with Article 9 GDPR).

If you give us your express consent to process personal data for specific purposes (e.g., disclosure to third parties, evaluation for marketing purposes, or advertising via email), the lawfulness of this processing is based on your consent in accordance with Art. 6 (1) (a) GDPR. Consent that has been given can be revoked at any time with effect for the future.

Where necessary and legally permissible, we process your data beyond the actual contractual purposes in order to fulfill legal obligations in accordance with Art. 6 (1) (c) GDPR. In addition, processing may take place to safeguard our legitimate interests or those of third parties, as well as to defend and assert legal claims in accordance with Art. 6 (1) (f) GDPR. If necessary, we will inform you separately, stating the legitimate interest, insofar as this is required by law.

Enquiries

If you send us personal data by contact form, e-mail, telephone, fax or other means, your data will be stored for the purpose of processing the enquiry and for the event of follow-up questions. We do not share this data with third parties without your consent.

The data will be deleted after processing the request or at the latest after termination of the contract, unless we have a legal obligation to retain your enquiry.

The basis for data processing is your consent and the fulfilment of a contract or pre-contractual measures (Article 6(1)(a) or (b) GDPR).

This also applies analogously to enquiries sent to our external data protection officer.

App

All of your data is safe with us. To use the app you do not need to provide any personal information, such as name or email address.

This keeps you anonymous and safe. No data can be traced back to you as a person, no advertising and no data sharing with third parties.

App and Teena

If you sync Teena with the Teena app, your app account is registered to your Teena serial number, which only you can know. 

During the login process you are provided a recovery key. This recovery key in combination with the serial number will allow you to recover the data in case you lose your phone.

Log files

We use ‘log files’ to collect and store information that you transmit to us automatically when using our online services. This data includes the browser type, browser version, app version, the operating system used, the original website, date, time, computer name, IP address and other platform data.

If technical problems arise, e.g. relating to security, these logs are evaluated. This data will be deleted as soon as possible, and at the latest after twelve months.

The basis for the data processing is the fulfilment of a contract or pre-contractual measures and also the legitimate interest of you and us to protect our online services in the best possible way (Article 6(1)(b) and (f) GDPR).

Statistics

Separately from personal data, we collect statistical data documenting the use of our online services. These procedures help us determine, for example, which parts of our offering are used most frequently.

At no time do we monitor you specifically as an identifiable individual.

The basis for data processing is a legitimate interest in improving our online services (Article 6(1)(f) GDPR).

Extensions

We use technologies from partners to extend our online services. This process involves processing personal data such as your IP address. Under no circumstances is your health information shared with our technology partners. The following technology partners are used in our online services:

Research and product improvement

 We would like to process your data for scientific research and product improvement. Your personal data will be anonymised for this purpose.

The basis for data processing is your consent.  (Article 6(1)(a) GDPR).

Legal obligations

The processing of your personal data is necessary to comply with our legal obligations (such as in respect of tax levies or criminal investigations). This may also include the disclosure of data to third parties (e.g. public prosecutors, courts or tax authorities).

The basis for data processing is the fulfilment of a legal obligation. (Article 6(1)(c) GDPR).

Disclosure

As a matter of principle, we only use your personal data within our company. In the event that we outsource certain parts of data processing (‘commissioned processing’), we contractually oblige the commissioned processors to use personal data only in accordance with the requirements of data protection laws and to ensure the protection of the rights of the data subject.

Internet

The protection of your data is our most important and central concern. Unfortunately, complete protection is not possible when transmitting data via the Internet, and therefore a residual risk remains despite all due care. If you are concerned about this, you should not use our online services.

We have however implemented a number of security mechanisms, such as encryption of your data, to protect your personal information and other data from third parties. We are constantly and actively working to further improve the protection of your data.

Rights

Certain data processing operations can only be performed with your explicit consent. You can revoke a consent previously granted at any time. An informal message to us by e-mail is sufficient for this purpose. The lawfulness of the data processing carried out prior to the revocation remains unaffected by the revocation.

Within the framework of the applicable legal provisions, you have the right to information about your stored personal data, its origin and recipients and the reason for data processing, free of charge and at any time, and also the right to the correction, blocking or deletion of this data where applicable. For this purpose, or if you have other questions concerning personal data, you can contact us at any time.

You have the right to have data that we process automatically on the basis of your consent or in performance of a contract passed to you or a third party in a current, machine-readable format. If you request the direct transfer of the data to another data controller, this will only be done to the extent that it is technically feasible.

You have the right to complain to the competent supervisory authority.

Changes

We reserve the right to change our privacy policy at any time if this becomes necessary as a result of new technologies, legal regulations or restructuring measures. You can always find the current version in our online offerings.
