Support Guidance
If you require support regarding the Sentinel Eligibility Checker, email mikey@mikeywhiston.dev with your enquiry. The Sentinel Eligibility Checker does not process or collect any personal data.
Privacy Policy
Sentinel Eligibility Checker (“the App”) respects your privacy. This Privacy Policy explains how information is handled when you use the App.
Information We Collect
Sentinel Eligibility Checker does not collect, store, transmit, or share any personally identifiable information (PII).
The App does not collect:
- Names or contact details
- Email addresses
- Phone numbers
- Location data
- User accounts
- Advertising identifiers
- Tracking information
- Analytics data
- Personal or sensitive information
On-Device Processing
Sentinel Eligibility Checker is designed around local, on-device processing.
Ticket eligibility checks, ticket interpretation, and validation logic are performed directly on your device. Information entered or scanned into the App is processed locally and is not uploaded to external servers.
Data Storage
The App does not create user profiles or maintain databases containing personal information.
Data used during an eligibility check is temporary and is not retained after processing unless explicitly stored by iOS as part of normal application functionality (such as app preferences).
Third-Party Services
Sentinel Eligibility Checker does not use:
- Advertising services
- Analytics platforms
- Tracking frameworks
- Data brokers
- External user databases
No information is sold, rented, or shared with third parties.
NFC and Ticket Data
If supported by your device, Sentinel Eligibility Checker may use device capabilities such as camera scanning or NFC reading to interpret transport ticket information.
Ticket data is processed locally on your device for the purpose of performing eligibility checks. The App does not transmit ticket information to external services.
Children’s Privacy
Because Sentinel Eligibility Checker does not collect personal information, it does not knowingly collect data from children or any other users.
Security
Since Sentinel Eligibility Checker does not collect or transmit personal information, there is no stored personal data held by the App requiring external protection.
The App relies on Apple’s built-in security features and platform protections.
Changes to This Privacy Policy
This Privacy Policy may be updated periodically to reflect changes to the App or applicable requirements. Any changes will be published on this page.
