At BP Logger, your privacy is our top priority. This Privacy Policy explains how we collect, use, store, and protect your personal and health information when you use our blood pressure tracking application.
Privacy-First Data Storage
By default, all your health data is stored exclusively on your device. You can use BP Logger without an account. We offer an optional account creation feature if you wish to back up your data and sync it across multiple devices.
The App uses an anonymous app-generated device identifier for guest users. If you create an account, we use your email for authentication and backup. We do not sell your data or share it for advertising purposes.
When you use BP Logger, you voluntarily provide health-related information, including:
Account creation is optional. You can use the App as a guest, or create an account to back up your data.
This identifier is not linked to your identity, email address, or any personal information.
We automatically collect certain technical information to ensure the App functions properly:
If you opt in to analytics in the App settings, we collect anonymized usage data to improve the App:
Important: Analytics data is strictly anonymous and does not include your blood pressure readings, medications, notes, or any personal health information. We use PostHog and Langfuse for this purpose.
You can opt out of analytics at any time in Settings → Data & Privacy.
What we collect when you contact us
When you submit feedback or contact us through the App or our website, we collect the information you provide (e.g., your email address and message). To protect the service and prevent abuse, our backend also automatically logs limited technical information associated with the submission, including your IP address, your browser or device user-agent, and basic request metadata (such as content length).
This information is used solely for operational purposes like rate limiting, spam and abuse prevention, and monitoring service health. It is stored alongside your feedback in our support system (Firebase) and is not used for advertising or sold to third parties.
We use the information we collect for the following purposes:
Storage and Backup Options
By default, your health data is stored exclusively on your device in a local SQLite database. If you choose to create an account, your health data is encrypted and backed up to our secure cloud servers (Firebase) to enable synchronization across your devices and prevent data loss if you lose your device.
✓ No Data Selling
We do not sell, rent, or trade your personal or health data. We do not share your blood pressure readings, medications, or notes with advertisers or third-party marketers. If you create an account, your email address is used solely for authentication and service-related communication.
We only share your information in the following limited circumstances:
We work with trusted third-party vendors to provide specific services:
Important: None of these vendors receive or have access to your blood pressure readings, medications, notes, or family member data. These vendors are contractually obligated to use your information only for the services they provide to us and to protect your data.
We may disclose your information if required by law or in response to:
You have full control over your data. You can exercise the following rights at any time:
You can view all your stored blood pressure readings, medications, and notes directly in the App.
Use the "Export my data" feature in Settings → Data & Privacy to download your complete health history as a CSV file.
You can edit or delete individual readings, medications, and family member profiles at any time within the App.
To permanently delete your health data:
Important: If you are using the App as a guest, uninstalling the App permanently removes all your data from your device. If you have an account, ensure you delete your account before uninstalling if you wish to remove data from our servers.
Go to Settings → Data & Privacy and toggle off "Share anonymized analytics" to stop sending usage data.
You can withdraw your consent to data processing at any time by uninstalling the App. This will permanently delete all your locally stored health data. You can also opt out of optional features like analytics at any time in the App settings.

BP Logger is operated from the United States. If you are located outside the United States, your data may be transferred to, stored, and processed in the United States.
