Privacy

What this site knows about you.

Last updated 19 August 2026

Short version: this website does not ask you for anything, and the tracker beta keeps your journal in your own browser until you decide otherwise.

This website

  • No account is required to read anything here.
  • No advertising, and no data sold or shared with advertisers.
  • If you submit the email form, your email address is sent to the form provider and forwarded to me by email. It is used to send occasional updates and nothing else. Every message includes an unsubscribe link, and you can ask me to delete your address at any time.
  • Web fonts and styles are served from this domain and from a public CDN. Those requests carry your IP address to the CDN in the ordinary way that loading any web page does.

Fill this in before publishing: if you run analytics (Plausible, Fathom, GA4) or any embedded third-party script, name it here and say what it collects. If you run none, say so explicitly — that is worth more to this audience than most features.

The tracker beta

  • Without an account: your fasts, meals, measurements and notes are stored locally in your browser. They are not transmitted to a server. Clearing your browser storage deletes them, and they do not follow you to another device or browser.
  • With an account: your journal is stored on the server so it can move between devices and into the full app later. It is associated with your email address.
  • Export and delete: you can export your journal from settings at any time, and you can ask for your account and its data to be deleted by emailing david@poeventuresllc.com.

Health information

Fasting, weight, glucose and ketone entries are personal health information, and they are treated that way. They are not sold, not shared with third parties for marketing, and not used to profile you. I am not a covered entity under HIPAA, so this is a commitment I am making rather than a regulation I am subject to — which is exactly why it is written down here.

Children

This site is not intended for anyone under 18 and accounts are not knowingly created for children. Extended fasting is not appropriate for children or adolescents.

Changes

If this policy changes in a way that affects what happens to your data, the date at the top will change and the change will be described here.
