About TheChemistTree

Sales 3,475
On Etsy since 2015

Chemistry connects people

Although formally educated as a scientist, Rovena Tey has always been creative. Since she was a little girl, she’s always been making things with her hands and learning art by doing.

Her science art focuses on the fascinating world of molecules and the fundamental fact that everything in the world is made up of chemicals -- our emotions, what we eat, what we smell, what we see, and even the things we touch. What started with chemistry has now grown to include math because the language of numbers is another way of explaining how the worlds works. Driven by curiosity about the everyday, the process starts with a bit of scientific wonder and cozying up in a nest of research papers before picking up the pen and paper to translate it into art. Her designs use vibrant colours and humour (puns), presenting a unique way of sharing her love of science + math with the world.

It’s called The Chemist Tree, a creative collection of fun paper + home goods for the inner nerd in all of us!

  • Rovena Tey

    Owner, Artist, Scientist

    Rovena studied science and became an artist by accident -- recycling a lab book cover by making a card. Learning chemistry better when professors drew structures by hand, she saw the art in chemical structures and The Chemist Tree was born.

Information I Collect:

To fulfil your order, you must provide me with certain information (which you authorised Etsy to provide to me), such as your name, email address, postal address, payment information, and the details of the product that you’re ordering. You may also choose to provide me with additional personal information (for a custom order, for example), if you contact me directly.

Why I Need Your Information and How I Use It:

I only use your information to customize your products.

Information Sharing and Disclosure:

Information about my customers is important to my business. I share your personal information for very limited reasons and in limited circumstances, as follows:

• Etsy. I share information with Etsy as necessary to provide you my services and comply with my obligations under both the Etsy Seller Policy and Etsy Terms of Use.

• Service providers. I engage certain trusted third parties to perform functions and provide services to my shop, such as delivery companies. I will share your personal information with these third parties, but only to the extent necessary to perform these services.

• Business transfers. If I sell or merge my business, I may disclose your information as part of that transaction, only to the extent permitted by law.

• Compliance with laws. I may collect, use, retain, and share your information if I have a good faith belief that it is reasonably necessary to: (a) respond to legal process or to government requests; (b) enforce my agreements, terms and policies; (c) prevent, investigate, and address fraud and other illegal activity, security, or technical issues; or (d) protect the rights, property, and safety of my customers, or others.

Data Retention:

I retain your personal information only for as long as necessary to provide you with my services and as described in my Privacy Policy. However, I may also be required to retain this information to comply with my legal and regulatory obligations, to resolve disputes, and to enforce my agreements. I generally keep your data for the following time period: 7 years.

Transfers of Personal Information Outside the EU:

I may store and process your information through third-party hosting services in Canada/US and other jurisdictions. As a result, I may transfer your personal information to a jurisdiction with different data protection and government surveillance laws than your jurisdiction. If I am deemed to transfer information about you outside of the EU, I rely on Privacy Shield as the legal basis for the transfer, as Google Cloud is Privacy Shield certified.

Your Rights

If you reside in certain territories, including the EU, you have a number of rights in relation to your personal information. While some of these rights apply generally, certain rights apply only in certain limited cases. I describe these rights below:

Access. You may have the right to access and receive a copy of the personal information I hold about you by contacting me using the contact information below.
Change, restrict, delete. You may also have rights to change, restrict my use of, or delete your personal information. Absent exceptional circumstances (like where I am required to store data for legal reasons) I will generally delete your personal information upon request.
Object. You can object to (i) my processing of some of your information based on my legitimate interests and (ii) receiving marketing messages from me after providing your express consent to receive them. In such cases, I will delete your personal information unless I have compelling and legitimate grounds to continue using that information or if it is needed for legal reasons.

Complain. If you reside in the EU and wish to raise a concern about my use of your information (and without prejudice to any other rights you may have), you have the right to do so by contacting Etsy directly.

How to Contact Me

For purposes of EU data protection law, I, Rovena Tey, am the data controller of your personal information. If you have any questions or concerns, you may contact me at hellochemisttree [!at] If you would like to contact me by snail mail, please e-mail me to obtain the mailing address.
