(SECUSO) Record condition, intensity, location, nature and time of your pain.
About this app
Privacy Friendly Pain Diary can help you track pain. It allows you to make daily diary entries recording your condition and the intensity, location, nature and time of the pain you feel, as well as the medication you take and additional notes. Records of your pain can help health professionals gain an insight into the pain you are experiencing.
The main view of the app is a calendar. A new diary entry can be added and existing diary entries can be viewed by selecting a day in this calendar. Diary entries can be exported to PDF. You have to specify a period of time for which the entries are to be exported. You also have the option to share that PDF.
Privacy Friendly Pain Diary has a daily reminder function. If enabled, it displays a notification reminding you to make a diary entry if you have not made one yet. You can set the time at which you want to be reminded in the settings.
How does Privacy Friendly Pain Diary differ from other similar apps? 1) Minimal permissions Privacy Friendly Pain Diary requires write access to your device’s storage if you wish to export your diary entries to PDF. All other features do not require any permissions.
2) Protection of privacy User data is not recorded, nor sent to any third party. The data you enter is only locally stored on your device.
3) No advertisements or tracking mechanisms Privacy Friendly Pain Diary distinguishes itself from many other applications in the way that it does not include any advertisements or tracking mechanisms. Advertisements can shorten battery life or consume mobile data, while tracking mechanisms can compromise privacy.
Privacy Friendly Pain Diary belongs to the group of Privacy Friendly Apps developed by the SECUSO research group at Karlsruhe Institue of Technology. Privacy Friendly Apps are Android applications which are optimized regarding privacy. Further information can be found here: https://secuso.org/pfa.

Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be org.secuso.privacyfriendlypaindiary is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.3.3 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Pain Diary (PFA) first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Pain Diary (PFA), and a listing is removed when the evidence for it stops holding up.
