3. General Information and Mandatory Information
Data Protection
The operators of these pages take the protection of your personal data very
seriously. We treat your personal data confidentially and in accordance with the
statutory data protection regulations and this privacy policy. When you use this
website, various personal data is collected. Personal data is data with which
you can be personally identified. This privacy policy explains what data we
collect and what we use it for. It also explains how and for what purpose this
happens. We point out that data transmission on the Internet (e.g., when
communicating by e-mail) can have security gaps. Complete protection of data
against access by third parties is not possible.
Information on the Responsible Party
The responsible party for data processing on this website is:
Ümit Sevim
Thomas-Mann-Strasse 11 90513 Zirndorf
Email: support@mathapex.app
The responsible party is the natural or legal person who alone or jointly with
others decides on the purposes and means of processing personal data (e.g.,
names, email addresses, etc.).
Storage Duration
Unless a more specific storage period has been specified within this privacy
policy, your personal data will remain with us until the purpose for data
processing no longer applies. If you assert a legitimate request for deletion or
revoke consent for data processing, your data will be deleted, unless we have
other legally permissible reasons for storing your personal data (e.g., tax or
commercial retention periods); in the latter case, deletion will take place
after these reasons no longer apply.
General Information on the Legal Basis for Data Processing on This Website
If you have consented to data processing, we process your personal data on the
basis of GDPR Article 6(1)(a) or Article 9(2)(a), if special data categories
according to Article 9(1) GDPR are processed. In the case of explicit consent to
the transfer of personal data to third countries, data processing is also
carried out on the basis of GDPR Article 49(1)(a). If you have consented to the
storage of cookies or access to information on your device (e.g., via device
fingerprinting), data processing is additionally carried out on the basis of
TTDSG § 25(1). Consent can be revoked at any time. If your data is required for
contract fulfillment or for the implementation of pre-contractual measures, we
process your data on the basis of GDPR Article 6(1)(b). Furthermore, we process
your data if this is necessary to fulfill a legal obligation on the basis of
GDPR Article 6(1)(c). Data processing may also be carried out on the basis of
our legitimate interest according to GDPR Article 6(1)(f). The relevant legal
basis in each individual case is informed in the following paragraphs of this
privacy policy.
Information on Data Transfer to the USA and Other Third Countries
We use tools from companies based in the USA or other data protection-wise
non-secure third countries. If these tools are active, your personal data may be
transferred to these third countries and processed there. We point out that no
data protection level comparable to the EU can be guaranteed in these countries.
For example, US companies are obliged to hand over personal data to security
authorities without you as a data subject being able to take legal action
against this. It cannot therefore be ruled out that US authorities (e.g.,
intelligence services) process, evaluate, and permanently store your data
located on US servers for monitoring purposes. We have no influence on these
processing activities.
Revocation of Your Consent to Data Processing
Many data processing operations are only possible with your express consent. You
can revoke consent you have already given at any time. The legality of the data
processing carried out until the revocation remains unaffected by the
revocation.
Right to Object to Data Collection in Special Cases and Against Direct
Advertising (Article 21 GDPR)
IF DATA PROCESSING IS CARRIED OUT ON THE BASIS OF ARTICLE 6(1)(E) OR (F)
GDPR, YOU HAVE THE RIGHT AT ANY TIME TO OBJECT TO THE PROCESSING OF YOUR
PERSONAL DATA FOR REASONS ARISING FROM YOUR PARTICULAR SITUATION; THIS ALSO
APPLIES TO PROFILING BASED ON THESE PROVISIONS. THE RESPECTIVE LEGAL BASIS ON
WHICH PROCESSING IS BASED CAN BE FOUND IN THIS PRIVACY POLICY. IF YOU OBJECT,
WE WILL NO LONGER PROCESS YOUR AFFECTED PERSONAL DATA UNLESS WE CAN
DEMONSTRATE COMPELLING LEGITIMATE GROUNDS FOR PROCESSING THAT OVERRIDE YOUR
INTERESTS, RIGHTS, AND FREEDOMS, OR THE PROCESSING SERVES TO ASSERT, EXERCISE,
OR DEFEND LEGAL CLAIMS (OBJECTION PURSUANT TO ARTICLE 21(1) GDPR).
IF YOUR PERSONAL DATA IS PROCESSED FOR DIRECT ADVERTISING, YOU HAVE THE RIGHT
TO OBJECT AT ANY TIME TO THE PROCESSING OF PERSONAL DATA CONCERNING YOU FOR
THE PURPOSE OF SUCH ADVERTISING; THIS ALSO APPLIES TO PROFILING TO THE EXTENT
THAT IT IS RELATED TO SUCH DIRECT ADVERTISING. IF YOU OBJECT, YOUR PERSONAL
DATA WILL SUBSEQUENTLY NO LONGER BE USED FOR THE PURPOSE OF DIRECT ADVERTISING
(OBJECTION PURSUANT TO ARTICLE 21(2) GDPR).
Right to Lodge a Complaint with the Competent Supervisory Authority
In the event of violations of the GDPR, data subjects have the right to lodge a
complaint with a supervisory authority, in particular in the Member State of
their habitual residence, their place of work, or the place of the alleged
infringement. The right to lodge a complaint exists without prejudice to other
administrative or judicial remedies.
Right to Data Portability
You have the right to have data that we process automatically on the basis of
your consent or in fulfillment of a contract handed over to you or to a third
party in a common, machine-readable format. If you request the direct transfer
of the data to another responsible party, this will only be done insofar as it
is technically feasible.
Right to Information, Correction, and Deletion
Within the framework of the applicable legal provisions, you have the right at
any time to free information about your stored personal data, its origin and
recipient, and the purpose of data processing and, if applicable, a right to
correction or deletion of this data. For this purpose and for further questions
on the subject of personal data, you can contact us at any time.
Right to Restriction of Processing
You have the right to request the restriction of processing of your personal
data. For this purpose, you can contact us at any time. The right to restriction
of processing exists in the following cases:
-
If you dispute the accuracy of your personal data stored by us, we usually
need time to verify this. For the duration of the verification, you have the
right to request the restriction of processing of your personal data. -
If the processing of your personal data was/is unlawful, you can request the
restriction of data processing instead of deletion. -
If we no longer need your personal data, but you need it to exercise,
defend, or assert legal claims, you have the right to request the
restriction of processing of your personal data instead of deletion. -
If you have lodged an objection pursuant to Article 21(1) GDPR, a balancing
of your and our interests must be carried out. As long as it has not yet
been determined whose interests prevail, you have the right to request the
restriction of processing of your personal data. -
If you have restricted the processing of your personal data, this data
may—apart from its storage—only be processed with your consent or for the
assertion, exercise, or defense of legal claims or for the protection of the
rights of another natural or legal person or for reasons of an important
public interest of the European Union or a Member State.
SSL or TLS Encryption
This site uses SSL or TLS encryption for security reasons and to protect the
transmission of confidential content, such as orders or inquiries that you send
to us as the site operator. You can recognize an encrypted connection by the
fact that the address line of the browser changes from “http://” to “https://”
and by the lock symbol in your browser line. If SSL or TLS encryption is
activated, the data you transmit to us cannot be read by third parties.
Objection to Advertising Emails
The use of contact data published within the framework of the imprint obligation
for the transmission of not expressly requested advertising and information
materials is hereby objected to. The operators of the pages expressly reserve
the right to take legal action in the event of the unsolicited sending of
advertising information, such as spam emails.
4. Data Collection on This Website
Contact Form
If you send us inquiries via the contact form, your details from the inquiry
form, including the contact details you provided there, will be stored by us for
the purpose of processing the inquiry and in case of follow-up questions. We do
not pass on this data without your consent. The processing of this data is based
on GDPR Article 6(1)(b) if your request is related to the fulfillment of a
contract or is necessary for the implementation of pre-contractual measures. In
all other cases, the processing is based on our legitimate interest in the
effective processing of inquiries addressed to us (GDPR Article 6(1)(f)) or on
your consent (GDPR Article 6(1)(a)) if this has been requested; consent can be
revoked at any time. The data you enter in the contact form will remain with us
until you ask us to delete it, revoke your consent to storage, or the purpose
for data storage no longer applies (e.g., after your request has been
processed). Mandatory legal provisions—in particular retention periods—remain
unaffected.
Inquiry by Email, Telephone, or Fax
If you contact us by email, telephone, or fax, your inquiry, including all
resulting personal data (name, inquiry), will be stored and processed by us for
the purpose of processing your request. We do not pass on this data without your
consent. The processing of this data is based on GDPR Article 6(1)(b) if your
request is related to the fulfillment of a contract or is necessary for the
implementation of pre-contractual measures. In all other cases, the processing
is based on our legitimate interest in the effective processing of inquiries
addressed to us (GDPR Article 6(1)(f)) or on your consent (GDPR Article 6(1)(a))
if this has been requested; consent can be revoked at any time. The data you
send to us via contact requests will remain with us until you ask us to delete
it, revoke your consent to storage, or the purpose for data storage no longer
applies (e.g., after your request has been processed). Mandatory legal
provisions—in particular statutory retention periods—remain unaffected.
