Privacy policy
We sell nothing, have no accounts and ask you for nothing. Here is the whole of it anyway.
Last updated September 2026
This covers breathigen.com. It is written to be read rather than skipped, so it is shorter than most and there is no table of defined terms.
All of it in a paragraph
This is a small publishing site: nothing to log into, nothing to buy here, no form anywhere. The sole piece of personal data that ever reaches us is an email address, and only because you typed it. The rest is headcount.
What is collected
If you email us
Your address and the contents of your message. Kept while the conversation is open, used to reply, deleted when it is done. You are not added to any list.
If you only read
Our host keeps ordinary server logs — a truncated IP address, the page requested, a timestamp, the browser string and the referring page. Every web server does this and it is how we find out something has broken.
We may count page views in aggregate using privacy-respecting analytics. We care which pages get read, not who read them, and no visitor profiles are built.
What is never collected
- Payment details. You never pay us, so no card ever reaches us.
- Names, addresses or phone numbers. There is no form here that asks.
- Health information. We do not ask what you take or why, and would rather not know.
- Anything belonging to a child. This is adult reading and is not aimed at under-18s.
Cookies
No advertising cookies and no cross-site trackers are set by this site. Affiliate links may carry a parameter in the URL so the seller can credit the referral — that parameter identifies the referring site, not you, and is read by them rather than stored by us.
Once you click through
Follow a buy button and you are immediately on another company’s site, governed by their privacy policy rather than this one. Name, address, card — whatever their checkout collects goes to them and never travels back here. Their policy is linked from the checkout and deserves a minute before you hand anything over.
Who else sees anything
Our hosting provider, because the site has to run somewhere, and an analytics provider if one is in use. Neither receives personal information from us and neither may sell what they process on our behalf. We would disclose information if a valid legal order required it, and would tell you wherever we were permitted to.
Your rights
Depending where you live you may be able to ask what we hold, have it corrected or deleted, or object to it being processed. Email hello@breathigen.com and we will deal with it. For almost every reader the honest answer is that we hold nothing, because you have never sent us anything.
Changes
If this policy changes materially the date at the top of the page changes with it. We keep no mailing list, so that date is the only notice we are able to give.
