Personal data within AIRONN HAVALANDIRMA SANAYİ ANONİM ŞİRKETİ is deleted, destroyed, or anonymized upon request by the data subject or ex officio in accordance with this destruction policy if the reasons stated in Articles 5 and 6 of the Law cease to exist.

The reasons stated in Articles 5 and 6 of the Law are as follows: a) Explicitly stipulated by laws. b) Necessity for protecting the life or physical integrity of the person who is unable to express consent due to actual impossibility or whose consent is not legally valid. c) Requirement for processing personal data of the parties to a contract if it is directly related to the establishment or execution of the contract. d) Necessity for the data controller to fulfill a legal obligation. e) The data subject has made their personal data public. f) Necessity for the establishment, exercise, or protection of a right. g) Processing of data is mandatory for the legitimate interests of the data controller, provided that it does not violate the fundamental rights and freedoms of the data subject.

3.2. METHODS OF DESTRUCTION

AIRONN HAVALANDIRMA SANAYİ ANONİM ŞİRKETİ deletes, destroys, or anonymizes personal data in accordance with the Law, other regulations, and the Personal Data Processing and Protection Policy, either upon request of the data subject or ex officio within the time frames specified in this Personal Data Retention and Destruction Policy.

The most commonly used deletion, destruction, and anonymization techniques by AIRONN HAVALANDIRMA SANAYİ ANONİM ŞİRKETİ are listed below:

3.2.1. Deletion Methods

Deletion Methods for Personal Data Held in Physical Format

• Redaction: Personal data in physical format is deleted using the redaction method. This involves removing personal data from documents by physically cutting it out where possible or making it unreadable with permanent ink in an irreversible manner.

Deletion Methods for Personal Data Stored in Cloud and Local Digital Environments

• Secure deletion via software: Personal data stored in cloud or local digital environments is deleted via digital commands in a way that prevents its recovery. Once deleted, these data cannot be accessed again.

3.2.2. Destruction Methods

Destruction Methods for Personal Data Held in Physical Format

• Physical destruction: Documents stored in physical format are destroyed using shredders in a way that prevents them from being reassembled.

Destruction Methods for Personal Data Stored in Local Digital Environments

• Physical destruction: This includes the melting, burning, or pulverizing of optical and magnetic media containing personal data to physically destroy the data.

• Degaussing: This method involves exposing magnetic media to a high magnetic field, thereby rendering the data unreadable.

• Overwriting: Data stored on magnetic and rewritable optical media is overwritten with random sequences of 0s and 1s at least seven times to prevent the recovery of old data.

Methods for Destruction of Personal Data Stored in the Cloud Environment

Secure Deletion from Software:

Personal data stored in the cloud environment is deleted using a digital command in a way that it can no longer be recovered. When the cloud computing service relationship ends, all copies of encryption keys necessary to make personal data usable are destroyed. Data deleted in this way becomes irretrievable.

3.2.3. Anonymization Methods

Anonymization is the process of making personal data unidentifiable or untraceable to any specific or identifiable individual, even if it is matched with other data.

• Removal of Variables:

This involves the removal of one or more direct identifiers in personal data that could be used to identify the individual. This method can be used both to anonymize the data or to remove information from personal data that is not relevant to the purpose of data processing.

• Regional Masking:

This involves the removal of identifiable information that may distinguish certain data within a dataset of anonymized personal data.

• Generalization:

This method aggregates personal data of many individuals, removing distinguishing information and converting it into statistical data.

• Lower and Upper Bound Coding / Global Coding:

Ranges for a specific variable are defined and categorized. If the variable does not contain a numerical value, closely related data within the variable is categorized. Values within the same category are then combined.

• Micro-Aggregation:

In this method, all records in the dataset are first ordered according to a meaningful sequence, then the entire dataset is divided into a specified number of subsets. Afterward, the average value for a variable of each subset is used to replace the individual value for that variable. This distorts indirect identifiers within the data, making it more difficult to relate the data to the individual.

• Data Scrambling and Distortion:

Direct or indirect identifiers in personal data are mixed with or distorted by other values to sever the link with the individual, causing them to lose their identifying characteristics.

AIRONN AIR CONDITIONING INDUSTRY INC. uses one or more of these anonymization methods according to the nature of the relevant data for anonymizing personal data. AIRONN AIR CONDITIONING INDUSTRY INC. may use K-Anonymity, L-Diversity, and T-Closeness statistical methods when applying these anonymization methods.
