What you type in the tools
Medicines, symptoms and destinations you enter are processed in your browser. They are not sent to our servers and we do not store them. Do not enter your name or other personal details into the search boxes.
Advertising
The free version shows ads from Google AdSense. Google and its partners use cookies to show ads and measure them, and may show ads based on your visits to this and other websites. You can turn off personalized ads at Google Ad Settings, and read how Google uses data at How Google uses information from sites that use its services. Ad-free subscribers do not load Google's ad code at all.
Ad-free plan
Payments are handled by Stripe; we never see your card number. We keep your Stripe customer id in a signed cookie on your device so the site knows to hide ads. If you ask for a sign-in link, we use your email only to look up your plan in Stripe and send the link.
Cookies we set
- adfree: only for subscribers, to switch ads off. Lasts up to 13 months.
- Browser storage that counts pages viewed this visit, so the ad-free reminder shows at most once a week.
