Privacy Policy
Last updated 11 August 2026 App version 1.5 Package com.pulselog.diary
The short version
PulseLog is a blood pressure and glucose diary that runs entirely on your phone. There is no account and no server, and PulseLog's own code never sends your readings anywhere. The app does include Google Play's billing library for the optional one-time purchase, and that library carries Android's standard internet permission — but it is never used to transmit any of your health data. What you log stays exactly where you put it: on this device.
What we collect
Nothing. PulseLog does not collect, transmit, or have access to any of your personal or health information. Specifically:
- No account or sign-in of any kind — we never ask who you are.
- No analytics, crash reporting, advertising, or tracking libraries.
- No health data ever leaves the device from PulseLog's own code. The app carries Android's internet permission only because Google Play's billing library (used for the optional one-time purchase) requires it — never to upload your readings.
Where your data lives
Your readings, notes, tags, profiles, and any profile photos you add are stored only in PulseLog's private app storage on your device, using an on-device database. Nothing is synced, backed up to the cloud automatically, or visible to any other app.
Backups, exports, and reports
PulseLog can create a JSON backup, a CSV export, or a PDF report — but only when you explicitly ask for one. Each of these is saved to a location you choose, using your device's standard file picker. You decide where that file goes and who you share it with; PulseLog has no part in that beyond creating the file.
Purchases
PulseLog is free to use. Logging, history, reminders, charts, averages and backups do not cost anything and are not time-limited. A single optional one-time in-app purchase unlocks saving and sharing the PDF report, CSV export, 90-day trends, and multiple profiles.
That purchase is handled entirely by Google Play Billing. PulseLog only ever learns whether the purchase was completed — it never receives your card details, billing address, or any other payment information. That is handled by Google, under Google's own privacy policy.
Earlier versions of PulseLog included a three-day trial period. That trial has been removed. The app still writes a single first-launch timestamp to its private storage on your device — a harmless leftover from that feature — but nothing reads or acts on it any more. Like everything else, it never leaves your phone.
If you delete the app
Because your data lives only on this device, uninstalling PulseLog or clearing its storage removes everything permanently — there is no copy anywhere else to recover it from. If you'd like to keep your history, make a backup first from Settings before you uninstall.
Changes to this policy
If this policy changes, the update will be posted here with a new "last updated" date. Since the app itself never phones home, we'd also state any material change in the app's own release notes.
