Affiliate links
Amazon purchase links include an affiliate tracking tag. When you follow a link, Amazon handles the visit under its own privacy and cookie policies. A manufacturer link also takes you to an external website with its own policies.
PRIVACY
Privacy policy
Which Safe is an informational buying guide. The current site does not provide visitor accounts, a newsletter subscription, or contact forms. The selector and planning tools run in your browser; the site code does not send your answers to a server or save them to a user profile.
Hosting and security
The hosting and security services delivering the site may process technical request information, such as IP addresses and browser details, and may use security cookies. This is separate from the local selector answers described above. The site’s application code does not currently include an analytics tracker.
Your choices
You can read the guides without using the tools or following a purchase link. Use your browser’s privacy and cookie settings to manage site data, and review the destination’s privacy notice before interacting with an external service.
Future changes
If the site adds analytics, subscriptions, or other collection features, this notice will need to describe them. This page was reviewed October 29, 2026.
