Introduction
This privacy policy (“Privacy Policy”) applies to all visitors and users of lightdash.com website and lightdash.cloud hosted services, Lightdash Community Slack and Lightdash Github project (https://github.com/lightdash) (collectively, the “Website” or “Websites”) and self-managed installations, which are offered by Telescope Technology Limited, Telescope Technologies Inc. and/or any of its affiliates (“Lightdash” or “we” or “us”) and describes how we process your personal data in connection with those Websites or self managed installations, customer events and demos, and how we collect information. It also tells you how you can access and update your personal data and describes the data protection rights that may be available under your country’s or state's laws. Please read this Privacy Policy carefully. By accessing or using any part of the Websites or self-managed installations, you acknowledge you have been informed of and consent to our practices with regard to your personal data.
Lightdash is an open source project and collaborative community, as well as a company. This means that some portions of our Websites (i.e. Lightdash Community Slack and Lightdash Github project), including information you voluntarily provide, will be public-facing for the open sharing of innovative developments, ideas, and information that makes our collaborative community so great. While we are committed to open sharing, we strive to respect the privacy of individual community members and will minimize the information we collect and share. If you do not want to share your information, including personally identifiable information, with other community members and the public, please be thoughtful as to how you interact with our Websites and what information you provide through the Websites (for example, through creating a public profile, project contributions, comments, and blog posts).
Unless otherwise stated, we act as the data controller for the data processing operations described in this Privacy Policy. We may provide additional information about our privacy practices in other places, for example, when we ask you to provide personal data in connection with a particular service or when you apply for a job with us.
This website is not intended for children, and we do not knowingly collect data relating to children.
We may update this Privacy Policy from time to time at our discretion and in particular to reflect any changes in applicable laws. If we do so, and the changes substantially affect your rights or obligations, we shall take commercially reasonable measures to notify you. Otherwise, you are responsible for regularly reviewing this Privacy Policy so that you are aware of any changes to it.
What Information Lightdash collects and why
Information from website visitors
Like most website operators, Lightdash automatically collects i) technical information about your device including your device's internet protocol (IP) address; and (ii) information about your visit to our Websites (the referral URL, the content viewed and the content interacted with). We collect this information to better understand how visitors use our Websites, to improve our Websites and experience for visitors, and to monitor the security of the Websites. For logged-in users to Lightdash Cloud deployments we also collect profile data, contact data, authentication data, support / communication data, payments data (if applicable). Lightdash also collects information about application usage using our own software and through conversations between you and Lightdash employees, to help us understand how to make the deployments more useful for different categories of users.
Usage data information from self-managed Lightdash instances
Lightdash automatically collects profile data and information about usage from each self-managed Lightdash instance. It is possible to opt out of your personal information being transferred. We never collect information on the contents of your connected databases, connection settings, database queries executed, or their results. Lightdash tracks the usage of these instances at an aggregate level. It is also possible to prevent this through modifying the code, which is made available to you.
Use of Google User Data
If you connect your Google account to your Lightdash instance, we may access certain Google user data through the Google Workspace APIs or Photos API to provide core functionality of our services. Any use of raw or derived data obtained through the Google Workspace APIs will adhere to the Workspace API User Data and Developer Policy, including Limited use of user data requirement. Any use of raw or derived data obtained through the Google Photos APIs will adhere to the Photos API User Data and Developer Policy including and the Limited use of user data requirement.
Lawful use of your personal data
We will only use your personal data where we have a lawful basis to do so. How we use your personal data depends on why we have collected it. The lawful purposes that we rely on under this Privacy Policy are:
consent (where you choose to provide);
performance of our contract with you or your employer or colleague;
compliance with legal requirements; and
legitimate interests. When we refer to legitimate interests, we mean our legitimate business interests in the normal running of our business which do not materially impact your rights, freedom, or interests.
Who do we share your data with?
For our legitimate interests, we may share your personal data with any service providers, sub-contractors, and agents that we may appoint to perform functions on our behalf and in accordance with our instructions, including payment providers, IT service providers, accountants, auditors, and lawyers. We shall provide our service providers, sub-contractors, and agents only with personal data that reasonably require to provide the service for us and if we stop using their services, we shall request that they delete your personal data or make it anonymous within their systems.
In order to comply with our legal obligations, under certain circumstances we may have to disclose your personal data under applicable laws and/or regulations, for example, as part of anti-money laundering processes or to protect a third party’s rights, property, or safety.
For our legitimate interests, we may also share your personal data in connection with, or during negotiations of, any merger, sale of assets, consolidation or restructuring, financing, or acquisition of all or a portion of our business by or into another company in which case we will send a notice to our users.
Your rights
You have a number of rights under applicable data protection legislation. Some of these rights are complex, and not all of the details have been included below.
Right to rectification: You can request us to correct errors in the personal data that we process for you if it is inaccurate, incomplete, or out of date.
Right to restriction of processing: In certain circumstances, you have the right to request that we restrict the processing of your personal information.
Right to be forgotten: You have the right at any time to request that we delete the personal data that we hold for you, where it is no longer necessary for us to hold it. However, whilst we respect your right to be forgotten, we may still retain your personal data in accordance with applicable laws.
Right to stop receiving marketing information: You can ask us to stop sending you information about our services.
You will not have to pay a fee to access your personal data (or to exercise any of the other rights). However, we may charge a reasonable fee if your request is clearly unfounded, repetitive, or excessive. Alternatively, we could refuse to comply with your request in these circumstances.
We may need to request specific information from you to help us to confirm your identity and ensure your right to access your personal data or to exercise any other right. This is a security measure to ensure that personal data is not disclosed to any person who has no right to receive it. We may also contact you to ask you for further information in relation to your request so we can deal with it promptly.
We try to respond to all legitimate requests within one month. Occasionally it could take us longer than a month if your request is particularly complex or you have made a number of requests. In this case, we will notify you and keep you updated.
If you have any complaints in relation to this Privacy Policy or otherwise in relation to our processing of your personal data, please tell us. We shall review and investigate your complaint and try to get back to you within a reasonable time. You can also contact the Information Commissioner, see www.ico.org.uk or if you are based outside of the United Kingdom, please contact your local data protection authority.
Retention of personal data
We will retain personal data in accordance with applicable laws.
If we have received your personal data because you are an employee of a customer, we shall retain your personal data until we no longer work with your employer, except where we are required to retain personal data for a particular period of time to comply with legal, auditory, or statutory requirements, including requirements of HMRC in respect of financial documents.
In some circumstances you can ask us to delete your data: see ‘Your rights’ above for further information.
In some circumstances we will anonymize your personal data (so that it can no longer be associated with you) for research or statistical purposes, in which case we may use this information indefinitely without further notice to you.
General
If any provision of this Privacy Policy is held by a court of competent jurisdiction to be invalid or unenforceable, then such provision shall be construed, as nearly as possible, to reflect the intentions of the parties and all other provisions shall remain in full force and effect.
This Privacy Policy shall be governed by and construed in accordance with the law of England and Wales, and you agree to submit to the exclusive jurisdiction of the English Courts.
