Privacy Policy

Effective: March 1, 2023.

Key Information

Purpose and who we are

The purpose of this Privacy Policy is to describe how Ivan Saldikov or our subsidiaries collects, uses, and shares information about you through our online interfaces (e.g., websites and mobile applications) owned and controlled by us, including but not limited to stdiff.io (referred to herein as the "Site"). Please read this Privacy Policy carefully to understand what we do. If you do not understand any aspects of our Privacy Policy, please feel free to contact us at Contact Us page. Your use of our Site is also governed by our Terms of Service. Terms used but not defined in this Privacy Policy can be found in our Terms of Service.

What Information this Privacy Policy Covers

This Privacy Policy covers information we collect from you through our Site. Some of our Site’s functionality can be used without revealing any Personal Data, but for features or Services related to the Content Offerings, Personal Data is required. In order to access certain features and benefits on our Site, you may need to submit, or we may collect, "Personal Data" (i.e., information that can be used to identify you and which may also be referred to as “personally identifiable information” or “personal information”). Personal Data can include information such as your name, email address, IP address, and device identifier, among other things. You are responsible for ensuring the accuracy of the Personal Data you submit to stdiff.io. Inaccurate information may affect your ability to use the Site, the information you receive when using the Site, and our ability to contact you. For example, your email address should be kept current because that is one of the primary manners in which we communicate with you.

What You Agree to by Using Our Site

We consider that the legal bases for using your personal information as set out in this Privacy Policy are as follows:

Which legal basis applies to a specific activity will depend on the type of personal information used and the context in which it is being used.

If we rely on our (or another party’s) legitimate interests in using your personal information, we will undertake a balancing test to ensure that our (or the other party’s) legitimate interests are not outweighed by your interests or fundamental rights and freedoms which require protection of the personal information. We may process your personal information in some cases for marketing purposes on the basis of your consent (which you may withdraw at any time as described below).

If we rely on your consent for us to use your personal information in a particular way, but you later change your mind, you may withdraw your consent by visiting your profile page and clicking the box to remove consent and we will stop doing so. If you withdraw your consent, this may impact the ability for us to provide some of our Services to you.

What Information We Collect

We gather the following types of information about users through the Site:

1. Information relating to your use of our Site. When users come to our Site, we may track, collect, and aggregate information indicating, among other things, which pages of our Site were visited, the order in which they were visited, when they were visited, and which hyperlinks were clicked. We also collect information from the URLs from which you linked to our Site. Collecting such information may involve logging the IP address, operating system, and browser software used by each user of the Site. We may be able to determine from an IP address a user’s Internet Service Provider and the geographic location of their point of connectivity. Location data may be used to route your traffic to the nearest regional server to reduce latency and improve your experience. We may also use cookies and web beacons when you visit our Site.

2. Personal Data provided directly by you or via third parties. We collect Personal Data that you provide to us when you register for an account, update or change information for your account, purchase products or Services, complete a survey, sign-up for email updates, participate in our public forums, send us email messages, and/or participate in Content Offerings or other Services on our Site. We may use the Personal Data that you provide to respond to your questions, provide you the specific Content Offering and/or Services you select, send you updates about Content Offerings or other stdiff.io events, and send you email messages about Site maintenance or updates.

Disclosure to stdiff.io Operations and Maintenance Contractors. We use various service providers, vendors, and contractors (collectively, "Contractors") to assist us in providing our Services to you. Our Contractors may have limited access to your Personal Data in the course of providing their products or services to us, so that we in turn can provide our Services to you. These Contractors may include vendors and suppliers that provide us with technology, services, and/or content related to the operation and maintenance of the Site or the Content Offerings.

We do not endorse and are not responsible for the privacy practices of these Third Party Sites.

Retention of Personally Identifiable Information

We keep your Personal Data for no longer than necessary for the purposes for which the Personal Data is collected and processed. The length of time we retain Personal Data for depends on the purposes for which we collect and use it and/or as required to comply with applicable laws and to establish, exercise, or defend our legal rights.

Confidentiality & Security of Personally Identifiable Information

We will use industry standard physical, technical, and administrative security measures to keep your Personal Data confidential and secure, and will not share it with third parties, except as otherwise provided in this Privacy Policy, or unless such disclosure is necessary in special cases, such as a physical threat to you or others, as permitted by applicable law. Because the Internet is not a 100% secure environment, we cannot guarantee the security of Personal Data, and there is some risk that an unauthorized third party may find a way to circumvent our security systems or that transmission of your information over the Internet will be intercepted. It is your responsibility to protect the security of your login information. Please note that e-mail communications are typically not encrypted and should not be considered secure.

Updating or Deleting Your Personal Data

You have certain rights in relation to your Personal Data. You can access your Personal Data and confirm that it remains correct and up-to-date, choose whether you wish to receive material from us or some of our partners, and request that we delete or provide you with a copy of your personal data by logging into the Site, selecting ‘Settings’ from the dropdown in the top right, and scrolling down to find the appropriate option. If you would like further information in relation to your rights or would like to exercise any of them, you may also contact us via Contact Us page.

We try to answer every request promptly where possible, and provide our response within the time period stated by applicable law. Keep in mind, however, that when deleting your Personal Data there may be residual information that will remain within our databases, access logs, and other records, which may or may not contain your Personal Data. Please also note that certain Personal Data may be exempt from such requests in certain circumstances, which may include if we need to retain your Personal Data to comply with a legal obligation. When you email us with a request, we may ask that you provide us with information necessary to confirm your identity.

Changing Our Privacy Policy

Please note that we review our privacy practices from time to time, and that these practices are subject to change. Any change, update, or modification will be effective immediately upon posting on our Site. We will notify you of any material change to this Privacy Policy by posting a notice on our Site’s homepage for a reasonable period of time following such update or by sending an email to the email address associated with your user account, and by changing the effective date (located at the top and bottom of this page). Be sure to return to this page periodically to ensure familiarity with the most current version of this Privacy Policy.

Any use or access by anyone under the age of 18 is prohibited, and certain regions and Content Offerings may have additional requirements and/or restrictions. In line with this belief, we do not knowingly collect or maintain Personal Data on our Site from persons under 18 years of age, and no part of our Site is directed to persons under 18 years of age. If you are under 18 years of age, then please do not use or access this Site at any time or in any manner.
