Business information from public sources

To make the Vendor Network useful from day one, we may create a profile for a stone business that has not joined yet, using publicly available business information, such as its name, town and country, website, products, photos, and office phone number or email address. To find a contact email the business publishes, we may use a web search service that reads its website and other public pages about it. We may email that address to invite the business to claim its profile; every such email has an unsubscribe link, and we stop when asked. The business can claim the profile and take it over, or ask us to correct or remove it.

• To provide and maintain the marketplace
• To connect stone buyers and vendors
• To process RFQs, listings, and messages
• To manage Premium subscriptions, credits, and listing boosts
• To verify business identities and prevent fraud
• To run the AI tools you choose to use, such as Compare with AI and Trade Intelligence
• To answer your support tickets and contact-form messages
• To produce aggregated analytics that help us improve the Platform
• To send service notifications and updates
• To comply with legal and regulatory obligations

• Everyone: Your public business profile (business name, town and country, vendor types, description, and photos) and your published listings can be seen by anyone who visits LithoPrime, including visitors who are not signed in and search engines.
• Premium members: Contact people and the office phone number and email address on a vendor profile are shown only to signed-in Premium members who choose to reveal them.
• The people you deal with: RFQs and buying requests are shown to vendors so they can respond, and chats and direct messages are shared with the users they are addressed to.
• Service providers: The companies listed in the next section process data on our behalf to run the Platform.
• Legal requirements: We may disclose information when required by law, court order, or government regulation.
• Business transfers: If LithoPrime is merged, acquired, or sells its assets, user data may be transferred as part of that transaction.

We use these providers to run LithoPrime. Each one only receives the data it needs for its job.

Hosting

Vercel runs the website. Our database runs on our own server in Germany.

File storage

Backblaze B2 stores the photos and documents you upload.

Email

ZeptoMail (by Zoho) delivers our emails, such as sign-in codes and notifications.

Payments

Dodo Payments processes payments for Premium plans, credit packs, and add-ons.

AI tools

Exa and xAI receive the text you enter into our AI tools (Compare with AI, Trade Intelligence, writing a buying request with AI, and the Freight Calculator) to produce the answer. Exa also reads public web pages for us, for example to find the contact email a business publishes.

Analytics and ads

Google Analytics, Google Ads, Meta, and LinkedIn, only if you choose "Accept all" in the cookie banner. See our Cookie Policy.

We use industry-standard security measures, including password hashing (bcrypt), encrypted connections (HTTPS/TLS), session-based authentication, and role-based access controls. However, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.

We keep your account data for as long as your account is active. If you ask us to delete your account, we will remove your personal data within 30 days, except where the law requires us to keep it (for example, tax records). Aggregated and anonymised data may be kept indefinitely for analytics.

LithoPrime connects buyers and vendors around the world, and our database is hosted in Germany. Some of the service providers above process data in other countries, including the United States and India. Where the GDPR or similar laws require it, we rely on appropriate safeguards such as standard contractual clauses.

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

• Access, correct, or delete your personal data
• Receive your data in a portable format
• Object to or restrict certain processing
• Withdraw consent where we rely on it
• Lodge a complaint with a data protection authority

You can download a copy of your data, or ask us to delete your account, from Settings → Your data in your dashboard. For anything else, email privacy@lithoprime.com or contact us.

We use essential cookies for sign-in, security, and remembering your cookie choice. With your consent ("Accept all" in the cookie banner), we also use analytics cookies to understand how the site is used, and advertising cookies from Google, Meta, and LinkedIn to show LithoPrime ads to people who have visited the site. You can change your choice at any time with "Cookie settings" at the bottom of every page. The full list is in our Cookie Policy.

Our marketing emails (news, offers and invitations, not account or security emails) contain a small image and links that tell us whether the email was opened and which links were clicked. We use this to see which emails are useful and to send fewer that aren't. Turning off images in your email app stops the image from loading, and the unsubscribe link in every such email stops these emails altogether.

LithoPrime is a business platform for people aged 18 or over (see our Terms of Service). We do not knowingly collect data from anyone under 18.

We may update this Privacy Policy from time to time. We will tell registered users about material changes by email or a notice on the Platform. If you keep using LithoPrime after a change, you accept the updated policy.

For privacy questions, email privacy@lithoprime.com, use our contact form, or open a support ticket from your dashboard.
