Kidney Care by nephroblogger (Android app and web app) · Last updated: 27 October 2026 (version 1.1.3)
Who we are
Kidney Care is a kidney health education app provided by nephroblogger, a consultant nephrologist and medical educator. In this policy, "we" and "us" mean the provider of Kidney Care.
In short
- Everything you record in the app (health tracker entries, quiz scores, reminders, bookmarks) is stored only on your own device.
- None of it is sent to us, to a server or to any third party. We cannot see it.
- You can delete all of it at any time with the Delete all my data button (Home → My Health, and Health Tracker).
- There are no accounts, no sign-in and no registration.
- There is no analytics, no tracking, no advertising and no cookies. The Android app contains no Google Play Services or advertising components.
- The Android app works fully offline. Its screens, learning library and images are stored inside the app.
Health data you choose to record
The Health Tracker lets you record, if you wish, the date, blood pressure, weight, creatinine, eGFR and urine albumin values. It is optional, and the first time you open it you are asked for your consent.
- Where it is stored: in the app's private storage on your device (local storage). It is not uploaded or backed up by us. The Android app does not take part in Android cloud backup.
- Who can see it: only you, and anyone who can unlock your phone and open the app. Please use your phone's screen lock.
- Trend charts are drawn on your device from those entries.
- Reports: the PDF and CSV reports are created on your device. They contain no name or personal identifier. They leave the app only if you tap Share or Save and choose where to send or save the file. What happens to a file after you share it is up to you and the app you chose.
- Deleting: each entry can be deleted on its own. The Delete all my data button removes every tracker entry, quiz score, reminder, bookmark, lesson progress, your consent and your settings from the device, and cancels scheduled reminder notifications. Uninstalling the app also removes the data.
Please do not type your name, ID numbers or other identifying details into any text box. The app does not ask for them.
Quiz, reminders and bookmarks
- Quiz: your scores, the date of each quiz and which questions you answered correctly are stored on your device so you can see your progress. They can be reset in the quiz progress page or deleted with Delete all my data.
- Reminders: the reminder text, date, time and repeat setting you enter are stored on your device and scheduled with the phone's own alarm system. The Android app asks permission to show notifications (Android 13 and later) and to restart reminders after the phone reboots. Reminders are an organiser only: the app gives no treatment advice. Please keep the reminder text short and free of personal details, because it appears in the notification. Reminders are never sent to a server.
- Bookmarks: the pages you bookmark in the Learn library are stored on your device.
Other things the app keeps on your device
- Which mode you chose (clinician, or patient and public), and your language choice. These are kept until you clear the app's data or change them.
- That you accepted the disclaimer, and the symptoms or findings you selected. These are kept only for the current session.
- Numbers you type into the educational calculators. They stay on the page while you look at that calculator and are not saved or uploaded. (If you tap "Save this eGFR to my Health Tracker", only that eGFR value is copied into a tracker entry that you then review and save.)
- How far you have read in a dialysis lesson (a module id and a step number only).
- Which general concerns you ticked on the appointment-prep checklist (concern ids only, for the current session).
- In the web version only, a copy of the app's own files so it can work offline.
You can remove all of this at any time with Delete all my data, by clearing the app's data in your phone settings, or by uninstalling the app.
Hosting (web version only)
The Android app runs from files stored inside the app and does not need to contact a server to work. The web version's pages are static files served from a web host over a secure (HTTPS) connection. Like any website, the host's servers receive standard technical information needed to deliver the pages (such as your IP address, device or browser type, and the time of the request), and may keep it briefly in server logs for security and reliability. We do not use this information to identify you, and we do not combine it with anything else.
Optional links (web version) and author profiles
In the Android app the About page lists optional links to the author's public social profiles; they open in your browser and are not needed to use the app. The app itself sends nothing to them.
In the web version only, at the end of the results, the app shows an optional WhatsApp link under the words "For personal guidance". You do not need to use it, and the app works fully without it. The main next step the app recommends is always to see your nearest nephrologist, or to go to emergency first if a warning sign applies.
If you tap the link, it opens WhatsApp (wa.me/923035529659) with a short neutral message already typed for you ("Hello, I would like some personal guidance about a kidney concern."). The app itself sends nothing and does not pass on your selections or any other information. A message is sent only if you choose to press send in WhatsApp. Anything you share in WhatsApp is handled under WhatsApp's own privacy policy, not this one.
Links to other websites
The app links to trusted sources of medical information and guidance, such as the NHS, NIDDK, NICE and KDIGO. These open in your browser, and those websites have their own privacy policies.
Children
Kidney Care is intended for adults (18 and over). It is not directed at children, and it does not knowingly collect information from anyone.
Medical education only
This is a medical education session, not personal advice. The app gives general information for education. It does not diagnose, and it does not replace a doctor who knows you. If you feel seriously unwell, call your local emergency number or go to the nearest emergency department.
Changes to this policy
If the app changes in a way that affects your privacy (for example, if analytics or accounts were ever added), this page will be updated before the change, with a new date at the top.
