Right to restriction of processing

Where processing of your personal data has been restricted, these data may, with the exception of storage, only be processed with your consent or for the establishment, exercise or defence of legal claims or for the protection of the rights of another natural or legal person or for reasons of important public interest of the Union or of a Member State.
If processing has been restricted under the above conditions, you will be informed by the controller before the restriction is lifted.

Right to erasure

You can obtain from the controller the erasure of your personal data without undue delay and the controller shall have the obligation to erase these data without undue delay where one of the following grounds applies:

  1. your personal data are no longer necessary in relation to the purposes for which they were collected or otherwise processed;

b) Exceptions

There is no right to erasure if processing is required for the establishment, exercise or defence of legal claims.

Right to information
If you have established the right to rectification, erasure or restriction of processing in relation to the controller, the controller is obliged to notify all recipients to whom your personal data has been disclosed of this rectification or erasure of the data or restriction of processing unless this proves impossible or would involve a disproportionate effort.
You have the right to be informed of these recipients by the controller.

Right to data portability
You have the right to receive your personal data, which you have provided to the controller, in a structured, commonly used and machine-readable format. You also have the right to have the right to transmit those data to another controller without hindrance from the controller to which the personal data have been provided, where

  1. the processing is based on a consent pursuant to point (a) of Article 6(1) GDPR or point (a) of Article 9(2) GDPR or on a contract pursuant to point (b) of Article 6(1) and;
  2. the processing is carried out by automated means.
In exercising this right, you also have the right to have the relevant personal data transmitted directly from one controller to another, where technically feasible. Freedoms and rights of other people may not impaired as a result of this.
The right to data portability shall not apply to processing of personal data that is necessary for the performance of a task carried out in the public interest or in the exercise of official authority vested in the controller.

Right to object
You shall have the right to object, on grounds relating to your particular situation, at any time to processing of your personal data which is based on point (e) or (f) of Article 6(1) GDPR, including profiling based on those provisions.
The controller shall no longer process your personal data unless the controller demonstrates compelling legitimate grounds for the processing which override your interests, rights and freedoms or where it serves the purpose of establishment, exercise or defence of legal claims.
Where your personal data are processed for direct marketing purposes, you shall have the right to object at any time to processing of your personal data for such marketing, which includes profiling to the extent that it is related to such direct marketing.
Where you object to processing for direct marketing purposes, your personal data shall no longer be processed for such purposes.
In the context of the use of information society services, and notwithstanding Directive 2002/58/EC, you may exercise your right to object by automated means using technical specifications.

Right to withdrawal of the declaration of consent under data protection legislation

You shall have the right to withdraw your declaration of consent under data protection legislation at any time. The withdrawal of consent shall not affect the lawfulness of processing based on consent before its withdrawal.

Automated individual decision-making, including profiling
You shall have the right not to be subject to a decision based solely on automated processing, including profiling, which produces legal effects concerning you or similarly significantly affects you. This shall not apply if the decision:

  1. is necessary for entering into, or performance of, a contract between you and the controller;
  2. is authorised by Union or Member State law to which the controller is subject and which also lays down suitable measures to safeguard your rights and freedoms and legitimate interests; or
  3. is based on your explicit consent.
However, these decisions may not be based on special categories of personal data referred to in Article 9(1) GDPR, unless point (a) or (g) of Article 9(2) applies and suitable measures to safeguard your rights and freedoms and legitimate interests are in place.
With regard to the cases referred to in points (1) and (3), the controller shall implement suitable measures to safeguard your rights and freedoms and legitimate interests, at least the right to obtain human intervention on the part of the controller, to express your point of view and to contest the decision.

Right to lodge a complaint with a supervisory authority
Without prejudice to any other administrative or judicial remedy, you shall have the right to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, place of work or place of the alleged infringement if you consider that the processing of your personal data infringes the GDPR.
The supervisory authority with which the complaint has been lodged shall inform the complainant on the progress and the outcome of the complaint including the possibility of a judicial remedy pursuant to Article 78 GDPR.
