Dropvel Privacy Policy

Effective date: 2026-11-01

Dropvel ("the app") is a free diabetes log provided by DDJ B1 ("we", "us"). You record blood glucose readings, insulin doses you have taken, carbohydrates, meal tags and notes; the app shows your readings against your own target range, averages and trends, an estimated A1c for reference, and can create a report you can show your care team. It has no account system, no login, no subscription and no server operated by us. Everything works offline. Dropvel is not a medical device and does not calculate or recommend insulin doses.

Your data

Your glucose readings, insulin entries, carbohydrate amounts, meal tags, notes, target ranges, units and settings are stored locally on your device.

• The app itself does not upload this data, and we never receive it.
• The advertising SDK described below may collect information as explained in that section. Your health entries (glucose, insulin, carbohydrates, notes) are not passed to the advertising SDK.
• If you use "Export CSV" or create a PDF report, the app writes a file containing your log to the location you choose with Android's file picker, or hands it to the app you choose through Android's share sheet. That file is controlled by you. "Import CSV" reads only the file you pick.
• If you use "Share", only the content you see (for example a report or a short message about the app) goes to the app you choose.
• Android's standard app backup may include app data in your own Google account backup if you have device backup enabled; that backup is controlled by you and Google, not by us.

Permissions

• Notifications — for optional reminders to log a reading. You can decline or turn them off; everything else keeps working.
• Run at startup — to restore reminders after the phone restarts or the time zone changes.
• Vibration — for reminder alerts, if you turn it on.
• Internet / network state / advertising ID — used by the advertising SDK described below. Some permissions declared by Google libraries (for example a foreground service used by system components) are not used by the app to read personal information.

Dropvel does not request location, contacts, camera, microphone, Bluetooth, phone call access, SMS, calendar or photo library permissions, or permission to draw over other apps. It does not connect to glucose meters or continuous glucose monitors.

Advertising and information collected automatically

The app displays advertisements provided by Google AdMob inside the app only (never in notifications or in the widget, and never on screens where you type, such as adding or editing an entry). Ads are limited to content rated for general audiences. To serve and measure ads and to prevent fraud, the AdMob SDK may collect and share with Google information such as your device's advertising identifier and other device identifiers, approximate location derived from your IP address, app interactions (for example ad views and taps), crash logs and diagnostics. This data is shared with Google as a third party for advertising, analytics and fraud prevention purposes. For more information see https://policies.google.com/technologies/partner-sites.

For users in the European Economic Area (EEA), the United Kingdom and other regions where required, the app presents a consent form via Google's User Messaging Platform (UMP) before personalized advertising data is used; if you decline, non-personalized ads are shown. You can change your choice from the app's Settings screen ("Ad privacy settings") and reset or limit ad personalization in your device settings.

Children

The app is not directed to children under 13, and we do not knowingly collect personal information from children.

Your rights

Your app data exists only on your device and in files or backups you control; uninstalling the app removes the app's own copies. You can edit or delete any entry inside the app at any time. Depending on your region (e.g. GDPR, CCPA), you may have rights regarding data processed by the advertising SDK; you can exercise ad-related choices through the consent form and your device's ad settings.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated effective date.
