Privacy & licence
The short version: what you build stays on your device. We count visits with Google Analytics, and you can switch that off below.
Your work stays with you
BioLender runs entirely in your browser. Your scenes, figures and settings are saved on your own device (in the browser's storage), and every picture, PowerPoint, SVG, PDF or 3D file is made on your computer. Nothing you build is uploaded to us. Clearing your browser's data for this site deletes your saved work, so keep copies of anything important (Save project, or export a .biofig figure project).
When BioLender goes online
Some library items load real data the first time you use them. Your browser then contacts that service directly, and the service sees the request (for example the protein or molecule name you searched for) and your IP address, under its own privacy policy:
| Service | Used for |
|---|---|
| RCSB Protein Data Bank | Protein and virus structures, PDB search |
| AlphaFold Protein Structure Database (EMBL-EBI) | Predicted human protein structures |
| PubChem (NCBI) | Molecules and molecule search |
| Human Reference Atlas (HuBMAP) | Reference organs |
| Wikimedia Commons | Reference photos |
Downloaded data is kept in your browser so it works offline afterwards.
Visit statistics (Google Analytics)
To learn how many people use BioLender and which parts they use, our pages load Google Analytics (the Google tag, measurement ID G-J4L5R3YKVT). It records things like the pages you open, your device and browser type, your approximate region and how long you stay, and it sets cookies (named _ga) to recognise a returning browser. It does not receive your projects, your figures or anything you type into BioLender. Google handles this data as described in Google's privacy policy.
The switch is remembered in this browser. If your browser sends Global Privacy Control, analytics never loads. You can also use Google's opt-out browser add-on.
Cookies
BioLender itself sets no cookies. The only cookies are Google Analytics' _ga cookies described above, and only while analytics is on.
Licence: using what you make
Pictures, figures, slides, videos and 3D files you make with BioLender are yours to use in your own work — papers, theses, posters, presentations, teaching and websites.
Some library items are built from open scientific data whose licence asks for a credit line. When your figure uses one of them, include its credit; in the 3D Studio, Figure credits lists the exact lines for what is in your scene.

Software
BioLender is built with three.js, three-mesh-bvh, three-bvh-csg and three-gpu-pathtracer (MIT), meshoptimizer (MIT), Lucide icons (ISC) and the Droid Sans typeface (Apache 2.0). The BioLender app and its hand-built library models are © the BioLender authors. Blender® is a trademark of the Blender Foundation; BioLender is an independent project and is not affiliated with it.
Good to know
BioLender's pictures are illustrations for communication and teaching. They are not drawn to exact scale unless an item says so, and they are not medical advice.
