Under Pressure is not a medical device and does not diagnose, treat, cure, or prevent any medical condition.
The short version
Under Pressure keeps a logbook of blood pressure readings you type in yourself. Those readings stay on your device. The application has no account, no sign-in, no analytics, no advertising, and no network permission at all. It cannot send anything anywhere, because the operating system will not let it open a connection.
Nothing is collected. Nothing is shared. Its Play Data Safety form names no data type, because there is none to name.
What is stored, and where
Everything you enter (readings, the times you took them, any note you attach, your reminder times and your protocol series) is written to a database inside the application's own private storage on your device. Other applications cannot read it. It is not copied anywhere else, and there is no server to copy it to.
Removing the application removes that database with it.
What leaves the device, and only when you send it
Two things can leave, and both of them are actions you take:
- Export. You choose export, the application writes a CSV or a summary document, and the system's own share sheet asks you where it should go. The application hands the file to whichever app you pick and has no part in what happens after that.
- Health Connect. If you turn it on, readings you have already entered are written to Android's Health Connect store, which is on your device and under your control. The permission this application holds is write only: it never reads what other applications have put there, and it has never asked for the permission that would let it.
Neither is automatic and neither happens in the background. If you never use them, nothing ever leaves.
What the application asks the system for
Four permissions, and each one is for a feature you can see:
- Notifications, asked for the first time you turn on a reminder, so a reminder can appear.
- Exact alarms, so a reminder lands at the time you set rather than whenever the system gets to it.
- Start after reboot, so your reminders survive a restart.
- Write blood pressure to Health Connect, asked for only if you open that room and turn it on.
There is no INTERNET permission. Two permissions that a bundled library
would otherwise have added, one for reading network state and one for foreground
services, are explicitly removed from the manifest, so they do not appear on the
application's permission list either.
Children
Under Pressure is for adults keeping their own logbook. It is not directed at children and collects nothing from anyone.
Changes
If this text ever changes, the version published on alangaudet.dev is the one that applies, and the date at the top of it says when it last moved.
