Privacy Policy

1. Information we collect

We collect the following categories of information when you use the Service:

• Account information you provide: your name, email address, password (stored in hashed form), organization or lab name, and any profile information you choose to add.
• Content you submit to the Service:samples, prep recipes, etchants, micrographs and other images, studies, equipment records, notes, and any other lab data you enter (collectively, your "Content").
• Communications you send us, including support requests, bug reports, and feedback.
• Information collected automatically when you use the Service: your IP address, browser type and version, device and operating-system information, referring and exit pages, pages and features accessed, sign-in events, timestamps, and similar diagnostic, analytics, and security logs.
• Cookies and similar technologies necessary to authenticate your session and to operate the Service securely. We do not use third-party advertising cookies or behavioral-advertising trackers.

2. How we use information

We use information for the following purposes:

• to provide, operate, maintain, secure, support, and improve the Service;
• to authenticate you and protect the integrity of accounts, Content, and the Service;
• to develop new features, products, and services;
• to respond to your support requests and other communications;
• to send you transactional and operational messages, including account, security, billing, and product updates;
• to detect, investigate, and prevent fraud, abuse, security incidents, and violations of our Terms of Use or applicable law;
• to comply with our legal obligations and to enforce our agreements; and
• to inform Pace Technologies' product development, marketing, and sales activities, as further described in the next section.

3. Pace Technologies and Materials Prep

Pace Technologies Corporation, the company that operates Materials Prep, also designs, manufactures, and sells metallography sample preparation equipment, consumables, and related products. The same Pace Technologies that operates Materials Prep also operates that hardware business; they are not separate companies, and there is no transfer of information between separate legal entities involved.

We may use the information described in Section 1, including account information and Content, to inform Pace Technologies' product, marketing, and sales activities. Specifically, we may use this information to:

• understand which equipment, consumables, materials, and methods are commonly used across our user base, in order to inform our product development and roadmap;
• consider how you use Materials Prep when deciding which Pace Technologies products, resources, or guidance might be useful to share with you, and when; and
• guide our customer-support and customer-success efforts.

This use is internal to Pace Technologies. We do not disclose your information, your Content, or any insights derived from them to any third party for that third party's own use, and the limits in Section 4 apply.

In practice, we keep direct outreach occasional and try to make it relevant to the work you do. If you receive a commercial email from Pace Technologies, you can unsubscribe at any time using the link included in that message. Unsubscribing does not affect transactional and operational messages necessary to provide the Service.

4. How we share information

We do not sell, rent, lease, or trade your information or your Content. We do not share your information or your Content with any third party for that third party's own purposes, including for that party's own marketing, advertising, analytics, or model training. We do not co-market with anyone using your information.

The only parties outside Pace Technologies that process your information do so as our service providers, under written contract, solely on our behalf and only to the extent necessary to operate the Service. They are not permitted to use your information or your Content for their own purposes. Our current service providers are:

• Supabase: database, authentication, and file storage.
• Vercel: application hosting and content delivery.
• Resend: transactional and operational email delivery.

We may update this list as our infrastructure evolves; the categories of permitted recipients (operational service providers acting on our behalf) will not change without notice.

We may also disclose information if we reasonably believe disclosure is required by law, legal process, or governmental request, or is necessary to protect the rights, property, or safety of Pace Technologies, our users, or the public, or to investigate suspected fraud, abuse, or violations of our Terms of Use. If Pace Technologies, Materials Prep, or substantially all of the assets of either is acquired by or merged with another entity, your information may be transferred as part of that transaction; we will notify you in advance of any such transfer.

5. Data retention and deletion

We retain your information for as long as your account is active and for a reasonable period thereafter to satisfy backup, audit, security, and legal requirements. Backups and operational logs may persist for additional time after deletion in accordance with their retention schedules. We may also retain de-identified or aggregated information indefinitely.

You may request deletion of your account by emailing us at the address below. We will process the request within a reasonable time. Some information may be retained where required by law or to protect our legal interests.

6. Security

We protect information using TLS in transit, encryption at rest, row-level security in our database, signed URLs for stored images, and access controls within Pace Technologies. No system or method of transmission over the internet is perfectly secure, and we cannot and do not guarantee the absolute security of your information.

7. Active development; risk of data loss

The Service is in active and ongoing development. Data formats, storage layouts, and features change frequently, and bugs, regressions, migrations, and outages can result in unintended changes to or loss of Content. You are responsible for maintaining your own backups and exports of any information you cannot afford to lose. We disclaim, to the maximum extent permitted by applicable law, liability for any such loss or alteration.

8. Your choices

You may review and update most account information by signing in to the Service. You may request deletion of your account by emailing pace@metallographic.com. You may unsubscribe from non-essential commercial email at any time using the link included in any such message. You may stop all messages from Pace Technologies (other than what is required to close out your account) by deleting your account.

Depending on where you live, you may have additional rights under applicable privacy law (such as rights to access, correct, port, or delete your information, or to object to certain uses). You may exercise any such rights by emailing us at the address below.

9. International users

Materials Prep is operated from the United States. If you access the Service from outside the United States, you understand that your information will be processed in the United States and other jurisdictions where we and our service providers operate, which may have data protection laws that differ from those of your country.

10. Children

Materials Prep is not directed to anyone under 16, and we do not knowingly collect information from children. If you believe a child has provided information to us, please contact us so we can delete it.

11. Changes to this Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes, we will provide notice through the Service or by email before they take effect. The "Effective" date above will always reflect the current version. Your continued use of the Service after changes take effect constitutes your acceptance of the updated Privacy Policy.
