Overview
Sinefour Labs LLC (“Sinefour,” “we,” “us,” or “our”) operates sinefour.com (the “Site”). This Privacy Policy explains what personal information we and the services supporting the Site may collect, how it is used or shared, and how to contact us about it. It applies to the Site and inquiries sent to our published contact address, not to any future products or services governed by a separate notice.
Information we collect
Information you provide. If you contact us by email, we may receive your name, email address, organization, message contents, attachments, and any other details you choose to provide.
Website and device information. When you visit, our hosting, security, and network providers may process information such as IP address, approximate location derived from IP address, browser or device information, requested pages, timestamps, and diagnostic or security logs.
The Site is currently intended as an informational website. Its HTML does not include account registration, a payment form, a newsletter signup, or a contact form.
How we use information
We use information as reasonably necessary to operate, deliver, maintain, and protect the Site; respond to questions, research inquiries, and collaboration requests; manage related correspondence; investigate misuse or security incidents; comply with applicable law; and protect our legal rights.
When information is shared
We may disclose information to service providers that support Site hosting, content delivery, email, security, or related business operations. These providers process data under their own applicable terms and privacy practices. We may disclose information in response to valid legal process or where reasonably necessary to protect people, security, or legal rights. If the company undergoes a merger, financing, acquisition, reorganization, or asset transfer, relevant records may be disclosed or transferred subject to applicable law.
We do not sell personal information collected through this informational Site and do not use its HTML to serve targeted advertising.
Retention and security
We retain correspondence and associated records only for as long as reasonably needed to respond to inquiries, keep appropriate business records, resolve disputes, enforce agreements, or comply with legal obligations. Hosting and security data may be retained according to provider configurations and policies. We take reasonable steps to safeguard information, but no method of transmission or storage is guaranteed completely secure.

Depending on your location and applicable law, you may have rights to request access, correction, deletion, or other controls over your personal information.
