Who we are

BP Sugar Diary is published on Google Play by Sangachadwam, an independent studio in India. Contact: support@sangachadwam.in.

What the app keeps, and where

The app keeps what you type: BP (top number, bottom number, pulse), sugar values with the date and time of each reading, the names of the people you keep diaries for, your reminder times and your settings. This is health information. It is stored only in the app's private storage on your phone.

We never ask for your phone number, contacts, location, photos, camera, microphone or Health Connect. The app cannot read your machine or meter; you type every number.

The words the app shows (Normal, High …) are worked out on the phone each time; nothing is sent anywhere to work them out.

Permissions the app asks for

Notifications, only when you switch a reminder on: to show your reminders. The app also uses the permission that brings your reminders back after the phone restarts.

Internet and network state: only to load the ad, and to skip it when you are offline. Advertising ID: used by the ad SDK (see Ads below). Vibration: touch feedback. Nothing else: no contacts, photos, files, location, camera, microphone, phone or exact alarms.

The Call 108 button opens your phone's dialer with the number filled in. The app cannot place the call by itself; you press call.

Internet use

The diary works fully offline. The app uses the internet only to show the ad and for Google Play services such as app updates.

We run no analytics or crash-reporting service in the app.

Ads

BP Sugar Diary shows one banner ad from Google AdMob at the bottom of the history page — never while you write a reading, never on the screen that tells you a reading needs action, and never before your first reading is saved.

To show ads, the Google Mobile Ads SDK collects your device's advertising ID, device information, your approximate location from your IP address, app interactions (such as an ad being shown or tapped) and diagnostics. Google receives this data. It does not include your readings or names.

Ads are not personalised unless you agree in the consent form. We block ad categories for health and medical products, drugs and supplements, weight loss, loans and dating.

You can reset or delete your advertising ID in Android settings at any time.

Backups

You can save a backup file of your diaries from the app. The file is saved where you choose (phone storage, Google Drive or elsewhere). We never receive it.

Android's own backup may copy the app's data to your Google account, as it does for most apps. You control this in Android settings.

When you share

A PDF, image or CSV goes only to the person or app you choose in your phone's share sheet. After that, their privacy policy applies.

Notifications

If you turn on a reminder, the app asks for permission to show notifications. Reminders are set on the phone; no message passes through us.

This website

This website sets no cookies, runs no scripts and uses no analytics. It is hosted on Cloudflare Pages, which keeps standard server logs.

Children

The app is meant for adults (18 and over) and is not directed at children.

Deleting your data

Because your readings are on your phone, you delete them yourself: one reading, one person's diary, or everything. To remove everything at once, uninstall the app or clear its storage in Android settings. Backup files are deleted where you saved them, and Android's backup is deleted from your Google account. You can reset your advertising ID in Android settings.

How to delete your data

Changes

If this policy changes, we update this page and its effective date before the app changes.
