MolDraw Snip privacy policy

In short

MolDraw Snip only looks at a page when you start a capture. It sends the small image you select to Mathpix to recognise the structure, then opens the result in MolDraw. It has no MolDraw server of its own, no analytics and no tracking, and it never sells or shares your data.

What the extension accesses

• A screenshot of the visible tab, taken only when you click Capture molecule, press the shortcut or use the right-click menu. It is cropped to the box you drag, and the rest of the screenshot is discarded.
• Your Mathpix app_id and app_key, which you enter yourself.
• Your settings: where to open structures (moldraw.com or a local editor) and whether to open them automatically.

It does not read page text, form fields, cookies, passwords or browsing history, and it does nothing on pages where you do not start a capture.

Where data goes

• Mathpix. The cropped image is sent over HTTPS to api.mathpix.com with your own API keys, so Mathpix can return the structure. Mathpix handles it under the Mathpix privacy policy and your Mathpix account settings.
• MolDraw. When you open a result, the recognised structure (molfile, InChI or SMILES, not the image) is put into a moldraw.com link. Molfiles go in the part of the URL after #, which browsers do not send to the server. Using moldraw.com is covered by the site privacy policy.
• Nothing is sent anywhere else.

What is stored

• Your Mathpix keys and settings are kept in Chrome's extension storage (chrome.storage.sync). If you use Chrome sync, Chrome syncs them across your own devices. MolDraw never receives them.
• On pages that block in-page capture, such as some PDFs, the screenshot is held briefly in local extension storage so the crop tab can show it. It is deleted as soon as the crop tab opens.
• Removing the extension deletes everything it stored.

Permissions and why they are needed

• activeTab: take the screenshot of the tab you are capturing, only after you start a capture.
• scripting: show the drag-to-select box on that tab.
• storage: remember your Mathpix keys and settings.
• contextMenus: add “Capture molecule with MolDraw” to the right-click menu.
• Access to api.mathpix.com: send the cropped image to Mathpix.

Limited use

MolDraw Snip's use of the data it receives complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. The data is used only to turn your selection into a structure. It is not used for advertising, is not sold, and is not read by people.
