This covers the In Her Rhythm © app and this website. It is written to be read, not to be survived.
The short version. Almost everything you put into the app stays on your phone. There are no accounts and no logins. On this website, the only thing collected is your name and email, and only if you type them in yourself. Nothing is ever sold, and there are no advertising trackers anywhere.

The following is stored on your device only and is never transmitted to us or anyone else:
Because this never leaves your phone, we cannot see it, access it, or recover it. If you delete the app, it goes with it.
The app offers optional one-time purchases: individual chapters and a full-walk bundle. Purchases are handled by Apple and by RevenueCat, Inc., which we use to validate and restore purchases across your devices. RevenueCat processes an anonymous purchase identifier, receipt information from Apple, and basic device and app information needed to deliver and restore what you bought. It is not used to identify you personally and it is not sold.
How they handle payment data: Apple Privacy · RevenueCat Privacy.
You can read every page of this site without giving anything. The only information collected is what you choose to type into a form.
Form submissions are stored by Netlify, who host this site. Netlify also keeps standard server logs, which include IP addresses, for security and abuse prevention. See Netlify's privacy policy.
If you tick the box on the quiz, or subscribe directly, your name and email are added to the In Her Rhythm © letters, which are sent through Substack. That means Substack holds your email address and can see whether you opened something. See Substack's privacy policy.
If you do not tick the box, you are not added. Either way, every letter has an unsubscribe link at the bottom, and using it removes you immediately and permanently. You never have to ask me.
This site does not use advertising or tracking cookies. It stores one small thing locally in your own browser: a note of which month you last saw the monthly message, so you are not shown it twice. It never leaves your device, it identifies nothing about you, and clearing your browser data removes it.
This site and the app link out to a free community space on Facebook, to the podcast on Spotify, Apple Podcasts, YouTube and Substack, to booking through Acuity Scheduling, and to the App Store. Once you follow one of those links you are with that service under its own terms and privacy policy. None of them receive your app data or your journalling.
In Her Rhythm © is intended for adults. It is not directed to children under 13, and we do not knowingly collect information from children.
You can ask what I hold about you, ask for a copy of it, ask for it to be corrected, or ask for it to be deleted. Email me and I will do it, usually the same week. There is no form and no process, it is just me.
If anything changes in a way that affects your privacy, for example if accounts, cloud sync or analytics are added in future, this page and the date at the top will be updated before that version ships.
