Terms & conditions

These terms govern your use of this site and the PIN early-access program. Please read them alongside the research disclaimers below.

1. Research and development status

PIN, developed by Breath IQ, is currently in the research and technology stage. Any capabilities, indicators, form factors, timelines and business models described on this site represent goals and intended direction, not shipped features or committed products.

Nothing on this site should be interpreted as a promise that a specific product, feature or health indicator will be delivered, or delivered on any particular timeline.

2. Not a medical device or medical advice

PIN is not a medical device and has not been cleared or approved by any regulatory authority. Nothing presented here is a diagnostic claim or medical advice.

Any wellness insight is separate from a medical claim. Any future diagnostic capability will follow appropriate clinical evidence and a defined regulatory pathway before it is offered as such.

3. Early access

Joining the early-access list registers your interest and does not create any obligation to purchase, nor an obligation by Breath IQ to provide a product or service. Access, if offered, may be limited and offered at our discretion.

We will use the email you provide to contact you about research updates, prototypes and availability. You can ask to be removed at any time.

4. Forward-looking statements

Statements about future products, capabilities, markets and business models are forward-looking and subject to change as research progresses. Actual outcomes may differ materially.

5. Contact

For questions about these terms, reach out through the early-access form on the home page.
