Glucio

Privacy Policy

Effective date: November 11, 2026

Glucio is a blood sugar diary for iPhone and Android. This policy explains what happens with your information. The short version: your health data stays on your phone, and we do not have a server that collects it.

Who we are

Glucio is developed and published by Sanjar Jabborov, an independent developer (“we”). Contact: sjabborov1204@gmail.com.

Data stored on your device

Your readings (blood sugar, date and time, fasting or meal, carbs and insulin if you enter them, tags and notes), HbA1c lab results, profiles, medications, reminders and settings are stored only in the app’s database on your device. We do not receive them. You do not need an account.

The system backup of your phone may include the app’s data, as for any app: on iPhone — an iCloud or computer backup, on Android — the Android backup to your Google account (end-to-end encrypted with your screen lock on recent Android versions). These backups are made and stored by Apple or Google for you, not by us; you control them in your phone’s settings.

Apple Health and Health Connect

If you turn it on, Glucio saves your own blood sugar readings to Apple Health (iPhone) or Health Connect (Android) and can read blood sugar readings back to restore your diary or to add readings from your meter’s app. This data is managed by Apple or Google on your device under their terms. Readings of other family profiles are never written there. Data read from Apple Health or Health Connect is used only to show it in your diary. It is never used for advertising, never sold and never shared with third parties.

Backup files, tables and reports

When you create a backup file, a CSV table or a PDF report, the file is created on your device and goes only where you send or save it (for example, Files, Google Drive, email or a messenger). Please keep these files safe: they contain your health data.

Photos of the meter screen (iPhone)

On supported iPhones, you can photograph your glucose meter’s screen. The number is recognized on the device by Apple Intelligence. The photo is not saved and is not sent anywhere.

No analytics, no ads

Glucio does not include advertising or third-party analytics, and it does not send usage data anywhere. If we ever add anonymous usage statistics, we will update this policy first, they will never include your readings or health data, and you will be able to turn them off in the app.

Purchases

Glucio Pro is sold through the App Store or Google Play. Payments are processed by Apple or Google; we do not receive your payment details. The app checks on your device whether Glucio Pro is active.

Reminders

Reminders are local notifications scheduled on your device. They are not sent through any server of ours.

Children

Glucio is not intended for children under 16, and we do not knowingly collect information from children.

Your choices and rights

You can edit or delete any reading in the app; deleted readings stay in “Recently deleted” for 30 days and are then erased. Deleting the app deletes its data from your device (copies you saved to Apple Health, Health Connect or backup files stay where you put them). Because we do not hold your health data, we cannot see, export or delete it for you — but you can always contact us with questions.

Changes

If this policy changes, we will update the date above and publish the new version on this page.
