How to choose a blood pressure app that keeps your readings private
A blood pressure log builds into a detailed health record: readings, pulse, the times you measure and, over months, a clear picture of your heart health. The point of keeping it is to share it with your doctor — on your terms. These checks show whether an app lets you do that without handing the record to anyone else first.
The checks
1. Does it make you create an account?
An account means a copy of your identity — and usually your data — on someone else's server. Many apps ask for one only to sync or to market to you. If the app works fully without signing up, there is one less place your information can leak from.
2. Where are your entries stored?
Look for a plain statement that data stays on your device, and for what happens when it does not: which server, in which country, encrypted or not. "Stored securely in the cloud" still means stored by someone else.
3. Does it contain trackers or advertising code?
On Android you can look any app up on Exodus Privacy (reports.exodus-privacy.eu.org), which lists the analytics and advertising code inside it. Zero is the number to look for. Advertising code in an app that holds sensitive records is a red flag.
4. What does the privacy policy say about sharing?
Search it for "share", "partners", "advertising", "affiliates" and "sell". A trustworthy policy for a personal-records app is short, specific and has little to say under those words.
5. Can you get your data out — and does it disappear if you stop paying?
You should be able to export everything in a standard format such as CSV or PDF at any time. Some apps lock your history behind a subscription; a fair one never takes away what you already recorded.
6. Which permissions does it ask for?
A tracker for one kind of record has no reason to want your contacts, location or microphone. Every permission it does not need is a door that does not have to be open.
How PressureKept answers these checks
What you record lives in an encrypted database on your own device. There is no account to create, no analytics watching you, and no server of ours holding a copy — so there is nothing for us to leak, sell or lose. Export your data whenever you like; nothing you have already written down disappears if you stop paying.
- Two taps and done — the app remembers the arm and position you used last.
- See the trend — 7-, 30- and 90-day averages, an AM/PM split, and a systolic/diastolic chart.
- Standard category colours — AHA-style labels shown for information, never as a diagnosis.
- Reminders to measure, scheduled on your own device rather than sent from a server.
- A doctor-visit PDF or CSV, written on your phone and shared only through the share sheet you open.
- Optional encrypted backup to a private folder in your own Google Drive — off unless you switch it on.
