How to Exercise Your California Rights
To exercise any of the rights above, contact us at GDPRDPO@circlesecurity.ai or call our toll-free number, 1-888-899-0452.
We will need to verify your identity before processing your request. To do this, we will generally ask for enough information to match you with the information we hold about you. If we need additional information to identify you, we will let you know.
We may decline a request to know, delete, or correct personal information where we cannot verify your identity or locate your information in our systems, or as otherwise permitted by law.
If an authorized agent submits a request on your behalf, no information will be disclosed until the agent's authority has been reviewed and verified. We may ask for additional information, such as your written authorization, to confirm it.

Data Security
The security of your personal information is very important to us. We use physical, electronic, and administrative safeguards designed to protect it.
However, no transmission of information over the internet is completely secure, and we cannot guarantee the security of personal information transmitted to our website. Any transmission of personal information is at your own risk. We are not responsible for the circumvention of any privacy settings or security measures on the website.
SSL/TLS encryption. This website uses SSL/TLS encryption to protect information in transit, such as the inquiries you send us. You can recognize an encrypted connection when your browser's address bar shows "https://" and a lock icon. Encryption helps protect the information you send us from being read by third parties while it is in transit.
Contact Form
If you submit our contact form, we collect your name, email address, and business name to respond to your inquiry and any follow-up questions. We do not share this information without your permission, except with the service providers that operate our website.
We retain the information you submit through the contact form until you ask us to delete it, withdraw your consent to its storage, or it is no longer needed for its purpose (for example, after we have answered your request). Mandatory statutory provisions, including required retention periods, are not affected.
Blog Subscription
To subscribe to our blog, you need to provide a valid email address. We do not collect any other information. We use your email address only to send you new blog posts and do not pass it on to third parties, other than the service providers that help us send them.
We keep your email address until you unsubscribe, at which point it will be deleted.
Jurisdiction Specific Terms: European Union and United Kingdom
Role under the GDPR. "GDPR" means the General Data Protection Regulation (EU) 2016/679 ("EU GDPR") and, for individuals in the UK, the EU GDPR as retained in UK law ("UK GDPR"). Circle Security is the controller of the personal information processed in connection with this website, because we use it for our own purposes as described in this Privacy Policy.
Personal data. For users in the EU or UK, references to "personal information" in this Privacy Policy include "personal data" as defined in the EU GDPR and UK GDPR. Personal data is information about an individual who is directly identified, or can be identified, from that information.
Legal bases for processing. The EU GDPR and UK GDPR require us to have a legal basis for each purpose for which we use your personal information. Our legal bases are:
- Where processing is necessary for our legitimate interests and your interests and fundamental rights do not override them ("Legitimate Interests").
- Where we need to comply with a legal or regulatory obligation ("Compliance with Law").
- Where we have your specific consent for the processing in question ("Consent").
Purpose: Legal basis
- Responding to contact form inquiries: Legitimate Interests
- Sending blog posts to subscribers: Consent
- Security: Legitimate Interests
- Compliance with law and cooperation with authorities: Compliance with Law
- Protection and enforcement of rights: Legitimate Interests
- Further uses: The original legal basis, if the further use is compatible with the purpose for which the personal information was collected
International transfers. We may share your personal information with third parties located outside the EU, the European Economic Area ("EEA"), or the UK. Whenever we transfer your personal information outside these regions, we ensure a similar level of protection by implementing at least one transfer mechanism recognized under the EU GDPR and UK GDPR, such as the European Commission's Standard Contractual Clauses (EU) or an International Data Transfer Agreement (UK).
Your Rights (EU and UK)
If you are in the EU or the UK, you have the following rights regarding how we collect, use, and disclose your personal information as a controller:
- Right of Access. You may request access to the personal information we hold about you.

- Right to Erasure ("Right to be Forgotten"). You may request that we delete your personal information in certain circumstances.
- Right to Restrict Processing. You may request that we restrict processing of your personal information.
- Right to Data Portability. You may request that we transfer your personal information to another organization, where technically possible.
- Right to Object. You may object to the processing of your personal information, including for direct marketing.
- Right Not to be Subject to Automated Decision-Making. You have the right not to be subject to decisions based solely on automated processing, including profiling, that produce legal effects concerning you.
To exercise any of these rights or to complain about how we handle your personal data, contact us at GDPRDPO@circlesecurity.ai or 1-888-899-0452.
Retention (EU and UK)
We retain personal information for as long as necessary to fulfill the purposes for which we collected it, including to satisfy legal, accounting, or reporting requirements, to establish or defend legal claims, or to prevent fraud. To determine the appropriate retention period, we consider the amount, nature, and sensitivity of the information, the potential risk of harm from unauthorized use or disclosure, the purposes of processing and whether we can achieve them by other means, and applicable legal requirements. Our retention periods are documented in our retention schedule.
Complaints
If you would like to complain about our use of your personal information or our response to your requests, you may contact us or submit a complaint to the data protection regulator in your jurisdiction.
