PRIVACY POLICY

INTRODUCTION

Our Privacy Notice describes our practices concerning data that you provide or that we may collect about you through the Services, and your consent to our use of data in compliance with our Privacy Policy.

Personal information is important to you. It is our goal to collect and use data consistent only with your consent, and as allowed or required by law and only for the time that we need your personal information. Thank you for entrusting your data with us. We promise to take your trust seriously and we hope to meet your expectations of data privacy.

We will collect your personal information as follows in order to send you the Draganfly newsletter and other exciting information about us. If you register on our website, then we will ask you for: your email information, business name, and general company description. We will also ask you if you are interested in becoming a partner or client.

CONSENT

We will inform you clearly which data we want to collect and how we want to use it so you can give informed consent. We do not use pre-ticked boxes and we ask you to positively show us your consent by ticking a box. You may withdraw consent at any time. If you wish to withdraw your consent or unsubscribe from any of our communications, you may contact us at: [email protected]. We will keep a record of when and how we get consent from you so that we can be accountable. It is our practice to regularly review consents to check that the relationship, the processing, and the purposes are consistent.

THESE ARE DATA PRIVACY RIGHTS THAT WE TAKE SERIOUSLY:

TO BE INFORMED ABOUT YOUR DATA

We collect your data to make our interactions smoother, and we will advise you of the purpose for which we collect personal data. We will ask for your permission if we want to use your personal information for another purpose. We will collect your personal information fairly, lawfully, for legitimate purposes only and where appropriate, only with your knowledge and consent.

Where your data is located:

We will advise you where your data is located and how we transfer your data as part of the services that we provide to you.

We protect your data and identity. We confirm that only you are accessing our website and services. Draganfly uses Amazon Website Services(AWS) with strong data protection policies [IS THIS TRUE?] . We will store your data at a AWS repository at our server and we can access or process that data from our US vendor. We will take all possible reasonable security safeguards against loss, unauthorized access, destruction, or improper disclosure of personal information.

If you are located internationally, cross border data transfers could occur if you conduct business in the future with Draganfly. This means that in order to execute our transactions, we will send or retrieve data across a border. Our trans-border data flows will be protected under secure principles that do not create obstacles to developing economic relations. We will transfer your personal data to fulfill a contract that we enter together with you, for example, to process a payment or other lawful purposes. Remember, that you can withdraw consent for marketing purposes at any time, but that we transfer data as part of a contract for services.

Account registration: If you register for an account with Draganfly, we will ask you for the following information: name and email address. We will send you updates on our business status. We will not expose you to advertising on our website.

ACCESS

You have the right to ask us for information that we have about you, and in most cases, we will try to do this for no charge. If there is a burdensome amount of information, then we will ask you for a nominal, reasonable fee. We will try to satisfy your request in under 30 days, which is the time that we have under law. If we are unable to fully comply with your request, you can appeal to the data supervising authority, and you must do that within thirty (30) days. We will, of course, try our best to deliver the data to you before that timeline.

RECTIFICATION

It is important for us to keep your trust, and so we will take care to keep your data accurate and to up to date. If you inform us of a change, then we will take steps to amend that data as soon as is reasonably possible. We want to make sure that any data we have about you is lawfully kept and that it is accurate.

ERASURE

You may ask us to delete your data and withdraw consent at any time. We will honor this request as allowed by law. After a reasonable, legal period of time, we will not keep your data. So, for example, if we end up doing business together through a contract, we will only keep the contract specific information as long as the pertinent laws require.

RESTRICT PROCESSING

At any time, you can inform us that you want us to restrict processing and we will satisfy that request as soon as reasonably possible. Some types of processing are required for us to continue our relationship with you. In those cases, you will be informed that it is not possible to restrict processing as requested and continue to be a client of Draganfly. Of course, we will always follow relevant laws about electronic record retention.

PORTABILITY

If you give electronic personal data either by 1) consent to store your data or 2) we enter into a contract with each other, then you can request us to provide you with machine-readable data of your account information. In the case that we would process your data via automated means, you would also have this right, called the Right to Portability.

RIGHT NOT TO BE SUBJECT TO AUTOMATED DECISION-MAKING INCLUDING PROFILING

Our technology does not employ automated decision making according to artificial intelligence. We protect you from that concern.

OBJECT

If you are a resident of the European Economic Area, the UK, or Switzerland, and you are not satisfied with our data processing methods, you may complain to the data privacy authority where you live.
