OpCheck Privacy Policy
Effective Date: January 01, 2025
Safeguard Analytics is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our mobile application for gas sensor management and calibration via Bluetooth.
1. Information We Do NOT Collect
OpCheck is designed to work entirely offline and locally on your device.
We do not collect, store, transmit, or have access to any of the following:
- Personal information (name, email address, phone number, etc.)
- Location data
- Device identifiers (beyond what’s temporarily needed for Bluetooth pairing)
- Sensor readings or calibration data after the session ends
- Usage analytics, crash reports, or diagnostic data sent to us
- Any other information that could identify you or your device over time
All device details, calibration processes, sensor data, and calculations happen exclusively on your device. No information is sent to our servers (because we do not operate any servers for this app) or to any third party.
2. Bluetooth Usage
The only hardware communication the app performs is Bluetooth Low Energy (BLE) connection to your gas sensor device for the purpose of:
- Discovering the sensor
- Reading current sensor values
- Writing calibration parameters
This communication occurs directly between your mobile device and the gas sensor — we do not act as an intermediary and we never receive this data.
Bluetooth permissions are requested only when you actively choose to connect to a sensor. You can revoke this permission at any time through your device settings.
3. Third-Party Services
OpCheck does not integrate any third-party analytics, advertising, crash reporting, or cloud services (such as Firebase, Google Analytics, Appsflyer, etc.).
If your app store platform (Google Play or Apple App Store) collects any data during download, installation, or update, that is governed by the respective platform’s privacy policy — not by us.
4. This Website
This section applies to safeguardanalytics.com, not to the OpCheck app. When you visit our website we record standard, non-identifying analytics: the pages viewed, the page you arrived from, any campaign tags in the link you followed, your approximate country, and your device type. We also perform a reverse-IP lookup that identifies the organization or internet provider whose network a visit came from — this tells us that a company visited, never who you are.
We do not store your IP address. It is converted into a one-way daily code used only to count unique visits, and that code cannot be traced back to you or linked across days. Our website also uses Google Analytics, the LinkedIn Insight Tag, and Apollo website visitor analytics for the same company-level and aggregate measurement purposes.
If you would prefer your visits not be recorded, most browsers offer tracking protection and you may also contact us to request removal.
5. Children’s Privacy
Our app is not directed to children under the age of 13 (or 16 in some jurisdictions). We do not knowingly collect any information from children.
6. Your Rights
Since we do not collect, store, or process any personal data, there is no personal data for you to access, correct, delete, or port.
You can stop all interaction with the app at any time by simply uninstalling it.
7. Security
Because no personal data is collected or transmitted, the main privacy risk is minimized. We still follow industry-standard secure coding practices for Bluetooth communication to protect against common vulnerabilities during the local sensor connection.
8. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. The updated version will be posted within the app and/or on our website (if any). We recommend reviewing this page periodically. Changes are effective when posted.
