What stays on your device
Your age, sex, pregnancy status, health conditions, prescribers, pharmacies, start dates and symptoms are used only inside your browser. We don’t have a server that receives them, we don’t have accounts, and we don’t store your list anywhere. (Ads are covered below.)
If you tick “Remember my list on this device,” your list is saved in your browser’s local storage on that device only. “Clear everything” removes it. We also remember that you’ve read the notice at the start, so it isn’t shown every time.
What is sent, and to whom
To look a medicine up, your browser sends the medicine name (and the ingredient names we find) to:
- the U.S. National Library of Medicine’s RxNav service (rxnav.nlm.nih.gov), to find the ingredients and drug classes; and
- the FDA’s openFDA service (api.fda.gov), to read the drug labels and recall reports.
Those requests come from your browser, so those government services see your IP address, as with any website. Nothing else about you is sent with them.
Advertising and cookies
This site shows ads to stay free. Third-party vendors, including Google, use cookies to serve ads based on your visits to this site and other sites. Ad partners may store and read cookies in your browser and may use web beacons, IP addresses or other identifiers to collect information while serving and measuring ads.
Google’s use of advertising cookies lets it and its partners serve ads based on your visits here and elsewhere. You can learn how Google uses this information at How Google uses information from sites or apps that use our services, and you can turn off personalized ads in your Google ad settings.
We don’t send your medicine list, conditions, prescribers or symptoms to any advertiser. The ad partners run their own code on the page and see what they see on any website they serve: your IP address, their cookies and the page address.
Fonts
Pages load fonts from Google Fonts, which sees your IP address when the font is downloaded.
