Privacy
Last updated 26 September 2026
In short
Your check-ins stay on your device. No account, no analytics, no ads, no server that receives what you write. Your answers are never sent to me, so there is nothing for me to read. While the app is in the TestFlight beta, Apple gives me the email address you join with — that part is below.
What the app stores
Your answers, the days they belong to, and your settings — all of it in the app's own database on your device, protected by your phone's own encryption.
Check-in durations go through Apple's logging system, so the app can be kept quick to fill in. Question names and durations are logged; answers never are. Those logs stay on your device.
iCloud sync
Off until you turn it on. With it on, your check-ins go to your own private iCloud database, where your answers are encrypted — Apple can't read them either. The dates are not encrypted, so a record of which days you logged, and which days you recorded a dose, is readable there.
Turning it off stops syncing and leaves what is already in iCloud. You can delete that from iCloud in the Settings app. Signing out of iCloud removes the synced copy from that device.
Apple Watch
The watch holds today's questions and answers, and any day it has finished but not yet handed over, and passes them to your iPhone directly. Nothing goes anywhere else.
Apple Intelligence
Summaries are written by a model running on your device. There is no server fallback: when it can't run, there's no summary.
Exporting
Export makes a CSV file and you choose where it goes. Once it leaves the app it isn't protected by it. The app says so at the moment you export.
The TestFlight beta
Joining the beta is between you and Apple. Apple gives me the email address you join with, and the name on it if you give one, so that I can see who is testing; I don't use it for anything else and there is no mailing list. If you send feedback or a build crashes, Apple sends me that too — the feedback you wrote, a screenshot if you attach one, and the crash, along with your device model and iOS version. None of that contains your check-ins.
This is the only part of Fluidity where anything reaches me. It ends when the app leaves the beta.
This site
Static pages on Cloudflare. No cookies, no analytics, no trackers, and no form to fill in. Cloudflare briefly records the addresses that connect, as any host does; I never see them.
Children
The app is not aimed at children under 13 and collects nothing from anyone.
Changes and contact
If this changes, the date above changes too. Anything affecting what leaves your device will be said in the app first.
