Jack Apps/Privacy
Privacy
All apps. Last updated 14 September 2026.
True of every app here: what you enter stays on your device, we collect
nothing, and the only thing that ever leaves is a purchase.
Common to every app
- No account. There is no sign-in, no email address, no profile. We could
not identify you if we wanted to, and we hold no database of users.
- No server of ours. Your entries are written to storage on the device and
read only by the app. Nothing is uploaded, backed up to us, or synced between devices.
- No measurement. No analytics, no advertising, no crash reporter, no
attribution, no tracking across apps or websites.
- Nothing sold or shared. There is nothing to sell, and no one to share it
with.
- Purchases are the exception. Payment is handled by Apple's App Store, and
RevenueCat, Inc. is the layer that tells the app whether a purchase is active. RevenueCat
receives the transaction and a randomly generated identifier for the installation, never
anything you typed into the app. Its policy is at
revenuecat.com/privacy. We never see your
payment details.
This website
Static HTML. It sets no cookies, runs no scripts, and loads no fonts, images or trackers
from anywhere else, which is why it is typeset in whatever font your device already has.
Nothing is logged beyond the request log the host keeps in the ordinary course.
Your rights
Because your records never leave your device, you exercise them directly: export or delete
them in the app, or delete the app to erase everything at once. There is nothing held by us
for anyone to access, port, correct or erase. For purchase records held by Apple or
RevenueCat, write to us and we will pass the request on.
Each app in detail
The apps store different things, so each has its own policy, and each is what its App
Store listing points at:
