Privacy Policy
Effective date: November 10, 2026Last updated: November 10, 2026
Qistone, Inc., a Delaware corporation (“Qistone”, “we”, “us” or “our”), operates the website at qistone.io (the “Website”). This Privacy Policy explains what personal information we collect through the Website, how we use and share it, and the choices and rights you have.
This policy applies only to the Website. Our products, Qistone, Qinnect and Qinn, are covered by their own privacy policies, available within each product. By using the Website, you acknowledge the practices described here.
The Website is intended for business users and is not directed to individuals under 18. We do not knowingly collect personal information from anyone under 18. If we learn that we have, we will delete it. If you believe someone under 18 has given us personal information, contact us at privacy@qistone.io.
1. Information We Collect
Information you give us. When you fill out a contact or demo-request form, subscribe to updates, apply for a job, or email us, we collect what you provide, such as:
- Name, email address, phone number, company and job title
- The content of your message or inquiry
- Job application details, such as your resume, education and work history
Please do not include sensitive information in a job application, such as government ID numbers or health information, unless we specifically ask for it.
Information collected automatically. When you visit the Website, we and our service providers automatically collect:
- Device and browser information, such as IP address, browser type, operating system and language
- Usage information, such as pages viewed, links clicked, referring URL, and time and date of visits
- Approximate location, derived from your IP address
Information from others. We may receive information about you from business partners, event organizers, or publicly available professional sources, for example when you attend an event we sponsor.
Information about other people. If you give us personal information about someone else, such as a colleague you refer to us, you confirm that you have their permission to do so.
We do not request sensitive personal information through the Website, such as government identifiers, precise geolocation or health data.
2. How We Use Information
We use personal information to:
- Respond to your inquiries and demo requests, and provide information about Qistone, Qinnect and Qinn
- Send newsletters and marketing emails you have signed up for
- Review job applications
- Operate, maintain, secure and improve the Website, and understand how visitors use it
- Measure and improve our marketing campaigns (with your consent where required)
- Detect, prevent and address fraud, abuse and security incidents
- Comply with legal obligations and enforce our terms
Email communications. If you sign up for updates, we may send you newsletters, product news about Qistone, Qinnect and Qinn, and event invitations. Email frequency varies. You can unsubscribe at any time using the link in any email or by contacting us at privacy@qistone.io. Subscribing is never required to use the Website. We will still send non-marketing messages, such as replies to your inquiries.
Text messages (SMS). If you give us your mobile number and agree to receive texts, we may send you service-related messages, such as replies to inquiries and meeting reminders. We send marketing texts only with your prior express written consent, which is not a condition of any purchase. Reply STOP to opt out at any time, reply HELP for help, or contact privacy@qistone.io. Message and data rates may apply, and message frequency varies. Wireless carriers are not liable for delayed or undelivered messages.
5. Retention
We keep personal information only as long as needed for the purposes in this policy. Typically:
- Inquiry and contact records: 24 months after our last interaction
- Newsletter and marketing data: until you unsubscribe
- Job applications: 12 months after the position is filled or closed
We may keep information longer when the law requires it or to establish or defend legal claims. We then delete or anonymize it.
6. Security
We use reasonable administrative, technical and physical safeguards to protect personal information, including encryption in transit and access controls. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
7. Your Privacy Rights
Everyone. You can unsubscribe from marketing emails using the link in any email, and manage cookies as described in Section 3. You can also contact us to access, correct or delete your information.
California residents. Under the California Consumer Privacy Act, as amended (CCPA), you have the right to:
- Know what personal information we collect, use and disclose, and request a copy of it
- Correct inaccurate personal information
- Delete personal information, subject to legal exceptions
- Opt out of the sale or sharing of personal information for targeted advertising
- Limit the use of sensitive personal information. We do not request or use sensitive personal information through the Website in a way that would give rise to this right.
- Not be discriminated against for exercising these rights
In the past 12 months, we collected these categories of personal information: identifiers (such as name, email address and IP address), professional or employment information, education information (from job applications), internet or other electronic network activity, and approximate geolocation. We collected them from the sources in Section 1, for the purposes in Section 2, and disclosed them to the recipients in Section 4. We “shared” identifiers and internet activity with advertising partners for cross-context behavioral advertising. We do not sell personal information, and we do not knowingly sell or share the personal information of anyone under 18.
California job applicants receive a separate notice describing how we handle applicant information when they apply.
Residents of other U.S. states. Residents of other states with comprehensive privacy laws may have similar rights. If we deny your request, you may appeal by replying to our decision. If your appeal is denied, you may contact your state Attorney General.
EU, UK and Swiss residents. Qistone, Inc. is the controller of personal information collected through the Website. We rely on these legal bases: your consent (for non-essential cookies and marketing, including measuring campaign effectiveness, where required), our legitimate interests (operating and improving the Website and responding to business inquiries), steps taken at your request before entering into a contract, and compliance with legal obligations. You have the right to access, correct, delete, restrict or object to processing of your personal information, to data portability, and to withdraw consent at any time. We do not use personal information collected through the Website for automated decision-making that produces legal or similarly significant effects.
How to make a request. Email privacy@qistone.io or submit a request through our contact form at qistone.io/contact-us (select “Privacy request”). To opt out of the sale or sharing of personal information, use the “Your Privacy Choices” link in the Website footer or turn on Global Privacy Control in your browser. We will verify your identity before acting on a request (except opt-out requests) and respond within the time the law requires. You may use an authorized agent, and we may ask for proof of their authority.
Complaints. If you believe we have mishandled your personal information or breached a privacy law, contact us at privacy@qistone.io with details of your concern. We will investigate and respond in writing with the outcome and any steps we will take. You also have the right to complain to a privacy regulator or data protection authority.
8. International Transfers
Qistone is based in the United States, and we process information in the U.S. and other countries where our service providers operate. When we transfer personal information from the EU, UK or Switzerland, we use appropriate safeguards such as the European Commission’s Standard Contractual Clauses.
9. Third-Party Links
The Website may link to third-party websites and services. We are not responsible for their privacy practices, and we encourage you to read their privacy policies.
