Privacy Policy

1. Introduction and scope

Effective date: October 28, 2026

Singletto Inc. ("Singletto," "we," "us," or "our") is a materials science company based in Seattle, Washington. We develop the Oxafence™ material technology and products that incorporate it.

This Privacy Policy explains how we collect, use, share, and protect personal information when you visit singletto.com and any other website that links to this policy (the "Sites"), buy products from us directly, contact us, sign up for updates, or otherwise interact with us (together, the "Services").

This policy does not cover purchases made through third-party marketplaces or distributors, such as Amazon. Those purchases are governed by the marketplace's or distributor's own privacy policy. It also does not cover information we handle on behalf of business customers under a separate written agreement.

2. Information we collect

We collect information you give us, information collected automatically when you use the Sites, and information from third parties.

Information you provide to us

  • Contact and inquiry information: name, email address, phone number, company or organization, job title, and the content of messages you send us through forms, email, or customer support.

  • Order information: when you buy directly from us, your name, shipping and billing address, email, phone number, and order details. Payments are processed by our payment and e-commerce providers; we do not store full payment card numbers.

  • Marketing preferences: your email address and preferences if you subscribe to our newsletter or updates.

  • Feedback and evaluations: responses you choose to give in surveys, product evaluations, or pilot programs.

  • Business and partnership information: information you share when you contact us about distribution, partnerships, investment, or employment.

Information collected automatically

  • Device and usage information: IP address, browser type, device type, operating system, referring URL, pages viewed, links clicked, and the dates and times of your visits.

  • Approximate location: general location (such as city or region) derived from your IP address.

  • Cookies and similar technologies: see Section 5.

Information from third parties

  • Service providers that help us run the Sites, process orders, and manage customer relationships.

  • Analytics providers that tell us how the Sites are used.

  • Business contacts, distributors, and event organizers who share your contact information with us in a professional context.

3. How we use information

We use personal information to run our business and provide the Services, including to:

  • Process and ship orders, and handle returns, exchanges, and warranty questions.

  • Respond to inquiries and provide customer support.

  • Send transactional messages, such as order confirmations and shipping updates.

  • Send newsletters and product updates if you have opted in. You can unsubscribe at any time.

  • Understand how the Sites are used so we can improve content, design, and performance.

  • Evaluate and improve our products, including through surveys and evaluation programs you choose to join.

  • Manage business relationships with distributors, partners, investors, and government customers.

  • Detect and prevent fraud, abuse, and security incidents.

  • Comply with legal, regulatory, and recordkeeping obligations, and enforce our terms.

We may also create de-identified or aggregated information that does not identify you, and use it for any lawful purpose.

4. How we share information

We do not sell your personal information, and we do not share it for cross-context behavioral advertising. We share it only as described below.

  • Service providers: companies that perform services for us under contractual confidentiality obligations, such as website hosting, e-commerce and payment processing, email and productivity tools, customer relationship management, analytics, and shipping and fulfillment.

  • Distributors and fulfillment partners: when needed to fill an order or answer a product question you sent to us.

  • Professional advisors: lawyers, accountants, auditors, and insurers, under duties of confidentiality.

  • Legal and safety: when we believe disclosure is required by law, subpoena, or other legal process, or is needed to protect the rights, property, or safety of Singletto, our users, or others.

  • Business transfers: in connection with a merger, financing, acquisition, reorganization, or sale of all or part of our business, subject to customary confidentiality protections.

  • With your consent: for any other purpose we describe when we ask for your permission.

5. Cookies and tracking technologies

We and our service providers use cookies, pixels, and similar technologies to operate the Sites, remember your preferences, and understand how visitors use the Sites.

  • Essential cookies keep the Sites working, for example to maintain a shopping cart or security settings.

  • Analytics cookies help us measure traffic and see which pages are useful. We use Squarespace Analytics and Google Analytics. You can opt out of Google Analytics by installing Google's opt-out browser add-on.

You can manage non-essential cookies through the cookie banner on the Sites, and you can block or delete cookies in your browser settings. Blocking some cookies may affect how the Sites work. Where required by law, we honor browser-based opt-out signals such as Global Privacy Control.

6. Data retention and security

We keep personal information only as long as we need it for the purposes in this policy, unless a longer period is required or allowed by law. For example, we keep order records as needed for tax, accounting, and warranty purposes, and we keep marketing contact information until you unsubscribe or ask us to delete it.

We use reasonable administrative, technical, and physical safeguards to protect personal information, including access controls and encrypted connections. No system is completely secure, so we cannot guarantee the security of information sent to or stored by us.

7. Your choices and rights

Marketing emails. You can unsubscribe using the link in any marketing email or by contacting us. We will still send transactional messages about your orders.

Privacy rights. Depending on where you live, you may have the right to:

  • Know or access the personal information we hold about you.

  • Correct inaccurate personal information.

  • Delete personal information, subject to legal exceptions.

You may use an authorized agent where the law allows; we may ask for proof of the agent's authority. If we deny your request, you may appeal by replying to our decision, and we will respond within the time required by law.

8. Children, international users, and third-party links

Children. The Services are not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has given us personal information, contact us and we will delete it.

International users. The Services are intended only for people in the United States. We do not market or sell to people in other countries, and we process and store information in the United States.

Third-party sites. The Sites may link to websites we do not control, such as online marketplaces, distributor sites, and social media. We are not responsible for their privacy practices, and we encourage you to read their policies.

9. Changes to this policy and contact us

We may update this Privacy Policy from time to time. When we do, we will change the effective date at the top. If we make material changes, we will give notice on the Sites or by email before the changes take effect.
