Thank you for choosing Gluco: Blood Sugar Tracker ("the App"), developed and operated by DT Hotel Ltd ("we", "us", "our"). We are deeply committed to maintaining our users' privacy through an ethical culture built on transparency, security, and trust.
Securing your personal information while you use our mobile application is one of our core principles. This Privacy Policy is designed to help you understand how we collect, use, disclose, and safeguard your information when you download, install, or use the App, as well as when you communicate with us via email or other electronic means.
Please read this policy carefully. By downloading, registering, or using the App, you consent to the collection, storage, and processing of your information as described in this Privacy Policy. If you do not agree with our policies and practices, please do not download, register, or use the App.
The information we collect depends on your usage of the App and your active participation in its features. We do not collect personal data as a mandatory requirement for basic, offline features to function.
We collect information that you voluntarily enter into the App when tracking your health metrics, creating an account, or contacting us for support. This information may include:
Account Details: User name, Email address.
Health and Demographic Metrics: Age, Gender, Weight, Height, and blood sugar log inputs.
Third-Party Login Data: If you choose to log in using a third-party platform (such as Google Sign-In), we may receive specific profile details from that provider, including your account name, email address, and public profile picture.
When you download, access, and use the App, it may automatically collect certain device and diagnostic data to ensure stability and proper functional delivery:
Device Information: We automatically identify the type of mobile device, operating system version, and unique device identifiers to deliver the optimized version of the App and provide appropriate technical support.
Analytics: We use third-party analytics tools, such as Google Analytics, to help us measure usage trends and traffic patterns. This data is collected in aggregate form and is used solely to improve our App's user experience.
Log and Crash Data: In the event of an error or crash within the App, diagnostic data called "Log Data" is collected through third-party crash reporting services. This may include your device's Internet Protocol (IP) address, device name, operating system version, the specific configuration of the App at the moment of the crash, and the time and date of the occurrence.
We guarantee that any personal or technical information collected will strictly be used to:
Deliver, maintain, and optimize the features of the App.
Respond to your support queries, feedback, or legal inquiries.
Prevent technical issues, crashes, or security vulnerabilities.
We do not sell, rent, or trade your personal data to third parties for commercial gains. Your data will never be used to market unrelated products. We will only disclose your data if required by law, such as to comply with a subpoena, court order, or similar legal process.
The security and privacy of your data are paramount to us. We adhere to generally accepted industry standards to protect your personal information during transmission and after we receive it. However, please be aware that no method of electronic transmission or mobile storage is 100% secure, and we cannot guarantee its absolute security.
Our storage and retention periods depend entirely on your chosen tracking method:
Local Storage (No Account): If you use the App without signing in to a cloud account, all of your logged health metrics are stored strictly on your physical device. Uninstalling the App will result in the immediate and permanent deletion of this data.
Cloud Backup (With Third-Party Account): If you register or log in using a third-party account, your log data is securely backed up on our servers to allow cross-device synchronization. This data is retained only for as long as necessary to provide you with active backup services.
You have the right to request the deletion of your personal data at any time.
In-App Deletion: You can delete your account and associated synchronized logs directly within the App's settings.
Email Deletion Request: You may contact us directly at dongtienhotel@gmail.com with the subject line "Data Deletion Request". We will process your request and permanently purge your data from our active servers within 30 days.
To ensure global compliance and protect our users, we respect and provide the following fundamental rights:
Right of Access: You have the right to receive confirmation of whether we are processing your personal data, and to request a copy of that data.
Right to Rectification: You can update or correct inaccurate or incomplete profile data and health logs directly in the App at any time.
Right to Withdraw Consent: Where data processing is based on your consent, you may withdraw your consent at any time. This will not affect the lawfulness of any processing carried out before your withdrawal.
Right to Erasure (The "Right to be Forgotten"): You can request that we completely erase your personal data from our systems under legally valid circumstances (e.g., if the data is no longer necessary for the purpose it was collected).
The App may contain links to external web platforms or integrate third-party developer software development kits (SDKs). These third-party services are governed by their own respective privacy policies:
Google Play Services: https://policies.google.com/privacy
AdMob / Google Ad Services: https://support.google.com/admob/answer/6128543?hl=en
Google Analytics: https://policies.google.com/privacy
We encourage you to review the privacy practices of any third-party services you interact with. We bear no liability or responsibility for the content, privacy policies, or actions of third-party platforms.
Gluco: Blood Sugar Tracker is intended for use by individuals who are at least 14 years of age or older. We do not knowingly collect, solicit, or maintain personal information from children under the age of 14.
If we discover that a child under 14 has registered for an account or provided us with personal information, we will take immediate action to delete that information from our records. If you are a parent or guardian and believe that your minor child has provided us with personal information, please contact us immediately at dongtienhotel@gmail.com.
We may update this Privacy Policy from time to time to reflect changes in our data practices, features of the App, or updated legal requirements. Any modifications will be posted directly within this document, and the "Last Updated" date at the top of this page will be updated accordingly.
