Privacy policy

Last updated: October 23, 2026

This Privacy Policy explains how we collect, use and share personal information when you visit or buy from biothm.com (the "Site").

Information we collect

  • Information you give us: your name, email address, phone number, shipping and billing addresses, order details, and the content of messages, reviews, newsletter sign-ups or affiliate applications you send us.

  • Payment information: card payments are handled by our third-party payment processor. We do not store full card numbers.

  • Information collected automatically: device and browser information, IP address, approximate location, pages viewed, referring website and how you use the Site. We collect this with cookies and similar technologies (see "Cookies and your choices").

How we use it

  • To process orders, arrange shipping, and handle returns, refunds and warranty claims

  • To communicate with you about your orders and answer your questions

  • To prevent fraud and keep the Site secure

  • To understand how the Site is used and improve it

  • To send marketing emails if you have agreed or where the law allows. You can unsubscribe at any time.

  • To show and measure advertising, according to your cookie choices

  • To comply with legal obligations

Where EU or UK law applies, our legal bases are: performing our contract with you, our legitimate interests (such as fraud prevention and improving the Site), your consent (for example for non-essential cookies and marketing), and legal obligations.

How we share it

We do not sell your personal information for money. We share it only as needed with:

  • our e-commerce platform provider (Shopify), which hosts the Site and processes orders

  • payment processors

  • shipping carriers and logistics partners

  • providers of customer-support chat, product reviews, email and affiliate tools

  • analytics and advertising partners, such as Google

  • authorities or professional advisers, where required by law or to protect our rights

Cookies and your choices

We use cookies that are needed for the Site to work, such as your cart and selected currency, as well as analytics and advertising cookies.

  • EU and UK visitors: analytics and advertising cookies are only used if you accept them in our cookie banner. You can change your choice at any time.

  • US visitors, including California residents: use the "Your Privacy Choices" link in the footer to opt out of the sale or sharing of your personal information for targeted advertising. We also honor Global Privacy Control (GPC) browser signals where required by law.

You can also block or delete cookies in your browser settings.

International transfers

We and our service providers may process your information outside your country, including in Hong Kong, mainland China and the United States. Where the law requires it, we use appropriate safeguards, such as standard contractual clauses.

How long we keep it

We keep personal information only as long as needed for the purposes above, including to meet legal, tax and accounting requirements. After that, we delete or anonymize it.

Your rights

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

  • access, correct or delete your personal information

  • receive a copy of it

  • object to or restrict certain processing

  • withdraw your consent

  • opt out of the sale or sharing of your information for targeted advertising
