Privacy Policy

Effective 18 August 2026

This policy describes how Seyrio handles personal information when you use the private flight Watch request service. The Terms of Use explain the service conditions.

1. Information you provide

For a Watch request, Seyrio currently asks for:

  • your email address;
  • the outbound origin airport;
  • the destination airport; and
  • exact departure and return dates.

2. Technical and security information

Hosting, network and security infrastructure may process standard technical details such as IP address, request path, browser or user-agent information, timestamps and diagnostic or security logs. The current Watch form does not use IP address as the identity of a Watch owner.

3. How information is used

Seyrio uses Watch information to:

  • receive, validate and manage a Watch request;
  • verify ownership of the email address;
  • send transactional messages about that request;
  • operate, secure and diagnose the service; and
  • prevent abuse and protect record integrity.

4. Verification and communications

Verification links are single-purpose, time-limited and designed to prevent trivial replay. Seyrio stores a derived hash of a verification token rather than the plaintext token. A verification link currently expires after 24 hours.

Verifying an email address does not activate automatic flight monitoring. Watch email is used for verification and other transactional Watch communication under the current product contract, not for marketing newsletters.

5. Service providers and sharing

Seyrio uses service providers that support the current Watch architecture:

  • Vercel for application hosting and runtime infrastructure;
  • Supabase for private Watch and operational database records;
  • Resend for verification and transactional Watch email delivery; and
  • flight-data providers for the route, date and search dimensions needed to obtain flight observations.

6. Sale and disclosure

Seyrio does not sell Watch personal information. Information may be disclosed to the providers above as needed to operate the service, or where disclosure is required to comply with law, protect the service or address security and abuse.

Under the current design, the Watch email address is not part of a flight-data provider request.

7. Retention

Seyrio keeps Watch requests, verification records and related operational records only for as long as needed for the purposes described above, record integrity, security and applicable obligations. Verification links expire after 24 hours.

A complete deletion schedule for unverified, verified, active, expired and cancelled Watch records has not yet been finalised. Until it is, records may remain in status-based storage rather than being automatically deleted on a promised date.

8. Your choices and rights

Depending on where you live, applicable law may give you rights to ask for access, correction, deletion, restriction or objection, or to make a complaint to a relevant authority. These rights are not absolute and may depend on the circumstances.

To ask a privacy question or make a request, contact communication@seyrio.com. We may need to verify that a request relates to you before acting on it.

9. International processing

Seyrio and its service providers may process information in more than one country. The exact processing locations depend on the provider and service configuration. This policy does not make claims about specific locations or transfer certifications that have not been verified.

10. Children

The Watch form does not ask for age, and Seyrio has not adopted a separate minimum-age rule for this service. Do not submit another person’s email address or travel request unless you are authorised to do so. Contact us if personal information was submitted without appropriate authority.

11. Changes and contact

We may update this policy as the Watch service or its data practices change. The effective date at the top identifies the current version. Questions about this policy may be sent to communication@seyrio.com.
