This Privacy Policy explains in detail how Blood Sugar Tracker ("we", "our", or "us") collects, uses, stores, shares, and protects your information when you use our Android application ("App"). We are committed to protecting your privacy and being fully transparent about how your data is handled. This application is designed to help users track and manage their blood sugar levels in a simple and effective way. Because this involves health-related information, we understand that your data is sensitive, and we take extra care to handle it responsibly, securely, and lawfully.
By using the App, you agree to the collection and use of information in accordance with this Privacy Policy.
The data controller responsible for your information is CARTYZO LIMITED, the developer of Blood Sugar Tracker. If you have any questions, concerns, or requests regarding your personal data, you can contact us at digital.mall.team01@gmail.com. We have also appointed a Data Protection Officer (DPO) to oversee data protection matters. The DPO can be contacted at the same email address, and is responsible for ensuring that your data is handled in compliance with applicable privacy laws.
We collect different types of information depending on how you interact with the application. The primary type of data includes health-related information that you manually enter into the app, such as blood sugar readings, notes, tags, and timestamps. This data is essential for the core functionality of the app and is generally stored locally on your device unless otherwise stated.
In addition, we may collect technical and device-related information such as your device model, operating system version, app version, language settings, and unique identifiers like advertising ID. This information helps us ensure that the app functions properly across different devices.
We also collect usage and analytics data, which includes how you interact with the app, the features you use, session duration, and crash reports. This information helps us improve performance, fix bugs, and enhance the user experience.
Certain information is collected automatically when you use the app, including your IP address and interactions with notifications and background services such as reminders.
We use your information to provide and improve the functionality of the app. This includes storing and displaying your blood sugar records, generating insights based on your entries, and sending reminders to help you maintain your health routine. We also use data to analyze app performance, identify technical issues, and improve stability.
Your data may also be used to understand general usage trends, which allows us to improve features and usability. In some cases, we may process your data to comply with legal obligations. Importantly, we do not use your health data for advertising purposes.
We process your personal data based on several legal grounds depending on your location. The primary basis is your consent, which is given when you enter data into the app or grant permissions. We also rely on legitimate interest to improve the app, ensure its security, and provide a better user experience. In certain cases, we may process data to comply with legal obligations.
For users in regions such as the European Union (under GDPR) and Brazil (under LGPD), these legal bases apply in accordance with local regulations.
Our application requires certain Android permissions to function properly, and each permission is used only for a clearly defined purpose.
The POST_NOTIFICATIONS permission is used to send reminders and alerts directly to your device. These notifications help you remember to log your blood sugar levels and stay consistent with your health tracking routine. The notification content is generated within the app and is not shared externally.
The SCHEDULE_EXACT_ALARM permission allows the app to schedule reminders at precise times. This is particularly important for users who need to check their blood sugar levels or take medication at specific times. Without this permission, reminders may not be accurate.
The USE_FULL_SCREEN_INTENT permission is used to display urgent alerts in full-screen mode when necessary. This ensures that critical reminders are not missed, especially in situations where timely action is important. This feature is only used for essential notifications and never for advertising.
The SYSTEM_ALERT_WINDOW permission allows the app to display small overlays or floating reminders over other apps. This makes it easier for users to quickly log their data or view reminders without interrupting their current activity. We strictly ensure that this feature is not used for misleading purposes or to collect sensitive information.
The RECEIVE_BOOT_COMPLETED permission allows the app to automatically restart reminder services after your device is rebooted. This ensures that your scheduled reminders continue to work without requiring manual setup again.
The WAKE_LOCK permission allows the app to briefly wake your device to deliver important reminders on time. This ensures that alarms and notifications are not missed due to the device being in sleep mode. This permission is used efficiently and only when necessary.
All permissions are used solely to support the core functionality of the app, and you can control or disable them at any time through your device settings.
We do not sell your personal data to third parties. However, we may share limited non-sensitive information with trusted service providers such as analytics tools and advertising networks, strictly for the purpose of improving the app and maintaining its functionality. In certain situations, we may also disclose information if required by law or in response to valid legal requests.
You have the right to know whether your data is shared, what data is shared, and with whom it is shared.
We retain your data only for as long as it is necessary to fulfill the purposes described in this policy. Health data that you enter into the app is stored until you choose to delete it. Analytics data is typically retained for up to 24 months to help us analyze long-term trends. Technical logs and crash reports are stored for shorter periods to assist with debugging and performance improvements.
You have the right to request deletion of your data at any time.
Depending on your location, you have various rights regarding your personal data. Under the GDPR (European Union), you have the right to access your data, correct inaccuracies, request deletion, restrict or object to processing, request data portability, and lodge a complaint with a supervisory authority.
Under the CCPA (California), you have the right to know what personal data is collected, request deletion, opt out of the sale or sharing of data, and receive equal service without discrimination.
Under the VCDPA (Virginia), you have the right to access, correct, and delete your data, as well as opt out of targeted advertising and data sales.
Under the LGPD (Brazil), you have the right to confirm data processing, access and correct your data, request deletion or anonymization, withdraw consent, and file complaints with the Brazilian data protection authority (ANPD).
You have full control over your data within the app. You can edit or delete your entries at any time, disable permissions through your device settings, stop notifications, or uninstall the app to stop all data collection.
You can opt out of certain types of data processing by disabling permissions, turning off personalized ads in your device settings, or contacting us directly to request data deletion or restriction. These options give you flexibility in managing your privacy preferences.
We implement appropriate technical and organizational measures to protect your data from unauthorized access, loss, or misuse. While we strive to use commercially acceptable means to protect your information, no method of transmission or storage is completely secure.
This application is not intended for children under the age of 13, and we do not knowingly collect personal data from children. If we become aware that such data has been collected, we will take steps to delete it promptly.
In some cases, your data may be processed or stored outside your country. When this happens, we ensure that appropriate safeguards are in place to protect your data in accordance with applicable laws.
We may update this Privacy Policy from time to time to reflect changes in legal requirements or app functionality. Any updates will be clearly indicated by revising the "Last Updated" date at the top of this document.
If you believe that your data protection rights have been violated, you have the right to lodge a complaint with your local data protection authority. We also encourage you to contact us first so we can try to resolve your concern.
By using the Blood Sugar Tracker app, you confirm that you have read, understood, and agreed to this Privacy Policy.
