Privacy Policy

The privacy of your data—and it is your data, not ours!—is a big deal to us. In this policy, we lay out: what data we collect and why; how your data is handled; and your rights with respect to your data. We promise we never sell your data: never have, never will.

This policy is split into sections. For your convenience, links to each of those sections is as follows:

• - What we collect and why
• - When we access or disclose your information
• - Your rights with respect to your information
• - How we secure your data
• - Data retention
• - Location of site and data
• - Changes & questions

This policy applies to all products built and maintained by SiliconFlow Inc. (Based in Singapore). This policy applies to our handling of information about site visitors, prospective customers, and customers and authorized users (in relation to their procurement of the services and management of their relationship with SiliconFlow). We refer collectively to these categories of individuals as "you" throughout this policy.

However, this policy does not cover information about a customer’s end users that SiliconFlow receives from a customer, or otherwise processes on a customer’s behalf, in connection with the services provided by SiliconFlow to the customer pursuant to an applicable services agreement (including the content of messages of customer end users ("End User Communications")). SiliconFlow processes End User Communications under the instructions of the relevant customer, which is the "data controller" or "business" (or occupies a similar role as defined in applicable privacy laws), as described in the applicable services agreement between such customer and SiliconFlow. SiliconFlow’s obligations as a "data processor" or "service provider" with respect to such information are defined in such services agreement and applicable data protection addendum and are not made part of this policy.

If you are a customer’s end user and you have questions about how your information is collected and processed through the services, please contact the organization who has provided your information to us for more information.

If you are a California resident, please click here to see our California Notice at Collection which includes additional disclosures as required by California law.

What we collect and why

Our guiding principle is to collect only what we need. Here’s what that means in practice:

Identity & access

When you sign up for a SiliconFlow product, we ask for identifying information such as your email address, name, and maybe a company name. That’s so you can personalize your new account, and we can send you product updates and other essential information. We may also send you optional surveys from time to time to help us understand how you use our products and to make improvements. With your consent, we may send you our newsletter and other updates. We may also give you the option to add a profile picture or similar personalization features that displays in our products.

We’ll never sell your personal information to third parties, and we won’t use your name or company in marketing statements without your permission either.

Billing information

If you sign up for a paid SiliconFlow product, you will be asked to provide your payment information and billing address. Credit card information is submitted directly to our payment processor and doesn’t hit SiliconFlow servers. We store a record of the payment transaction, including the last 4 digits of the credit card number, for purposes of account history, invoicing, and billing support. We store your billing address so we can charge you for service, calculate any sales tax due, send you invoices, and detect fraudulent credit card transactions. We occasionally use aggregate billing information to guide our marketing efforts.

Product interactions

We store on our servers the content that you upload or receive or maintain in your SiliconFlow product accounts. This is so you can use our products as intended, for example, to create deployments of your AI algorithms on our platform. We keep this content as long as your account is active.

General Geolocation data

We may log the full IP address used to sign up a product account and retain that for use in mitigating future spammy signups. We may also log all account access by full IP address for security and fraud prevention purposes, and we keep this login data for as long as your product account is active.

Website interactions

We collect information about your browsing activity for analytics and statistical purposes such as conversion rate testing and experimenting with new product designs. This includes, for example, your browser and operating system versions, your IP address, which web pages you visited and how long they took to load, and which website referred you to us. If you have an account and are signed in, these web analytics data are tied to your IP address and user account until your account is no longer active. The web analytics we use are described further in the Advertising and Cookies section.

Third-Party Services and Cookies

If you link, connect, or login to the SiliconFlow Platform with a third-party service (e.g., Google, Facebook, GitHub), you direct the service to send us information such as your registration, friends list, and profile information as controlled by that service or as authorized by you via your privacy settings at that service.

We also use persistent first-party cookies and some third-party cookies to store certain preferences, make it easier for you to use our applications, and perform A/B testing as well as support some analytics.

A cookie is a piece of text stored by your browser. It may help remember login information and site preferences. It might also collect information such as your browser type, operating system, web pages visited, duration of visit, content viewed, and other click-stream data. You can adjust cookie retention settings and accept or block individual cookies in your browser settings, although our apps won’t work and other aspects of our service may not function properly if you turn cookies off.

Voluntary correspondence

When you email SiliconFlow with a question or to ask for help, we keep that correspondence, including your email address, so that we have a history of past correspondence to reference if you reach out in the future.

We also store information you may volunteer, for example, written responses to surveys. If you agree to a customer interview, we may ask for your permission to record the conversation for future reference or use. We will only do so with your express consent.

When we access or disclose your information

We may disclose your information at your direction if you integrate a third-party service into your use of our products. For example, we may allow you, at your option, to connect your account on other platforms to SiliconFlow so that you can use SiliconFlow together with such third party platforms. Information that you transmit between SiliconFlow and third party platforms may be stored by both SiliconFlow and third party platforms.

No SiliconFlow human looks at your content except for limited purposes with your express permission, for example, if an error occurs that stops an automated process from working and requires manual intervention to fix. These are rare cases, and when they happen, we look for root cause solutions as much as possible to avoid them recurring. We may also access your data if required in order to respond to legal process (see "When required under applicable law" below).

To help you troubleshoot or squash a software bug, with your permission. If at any point we need to access your content to help you with a support case, we will ask for your consent before proceeding.

Aggregated and de-identified data.We may aggregate and/or de-identify information collected through the services. We may use de-identified or aggregated data for any purpose, including marketing or analytics.

When required under applicable law.All data infrastructure from SiliconFlow are located in the U.S.

• - Requests for user data. Our policy is to not respond to government requests for user data unless we are compelled by legal process or in limited circumstances in the event of an emergency request. However, if U.S. law enforcement authorities have the necessary warrant, criminal subpoena, or court order requiring us to disclose data, we must comply. Likewise, we will only respond to requests from government authorities outside the U.S. if compelled by the U.S. government through procedures outlined in a mutual legal assistance treaty or agreement. It is SiliconFlow policy to notify affected users before we disclose data unless we are legally prohibited from doing so, and except in some emergency cases.
• - Preservation requests. Similarly, SiliconFlow policy is to comply with requests to preserve data only if compelled by the U.S. Federal Stored Communications Act, 18 U.S.C. Section 2703(f), or by a properly served U.S. subpoena for civil matters. We do not disclose preserved data unless required by law or compelled by a court order that we choose not to appeal. Furthermore, unless we receive a proper warrant, court order, or subpoena before the required preservation period expires, we will destroy any preserved copies of customer data at the end of the preservation period.
• - If we are audited by a tax authority, we may be required to disclose billing-related information. If that happens, we will disclose only the minimum needed, such as billing addresses and tax exemption information.

Finally, if SiliconFlow is acquired by or merges with another company — we don’t plan on that, but if it happens — we’ll notify you well before any of your personal information is transferred or becomes subject to a different privacy policy.

If we are unable to verify you, we may be unable to respond to your requests. If you have questions about exercising these rights or need assistance, please contact us at [email protected]. If an authorized agent is corresponding on your behalf, we will need written consent with a signature from the account holder before proceeding.

Depending on applicable law, you may have the right to appeal our decision to deny your request, if applicable.
