These terms govern your use of the Kestrel mobile app and the Kestrel sidecar (together, “Kestrel”), provided by Pingnest. By installing or using Kestrel you agree to them. If you do not agree, do not use Kestrel.
Kestrel is a client for your own self-hosted Frigate NVR. It connects directly to hardware you own and operate. Kestrel is an independent project and is not affiliated with or endorsed by the Frigate project. You are responsible for your own server, cameras, network, and for complying with all laws that apply to your recording and monitoring (including notice/consent requirements where you live).
The core app — live view, recordings, review, settings, sidecar pairing and fully-local notifications — is free. Kestrel Pro unlocks the optional cloud push relay, which delivers alerts to your phone while the app is closed (see the Privacy Policy for exactly what it transmits). Cloud push is off until you enable it.
Use Kestrel only with servers and cameras you own or are authorized to access. Do not use it to break the law, infringe others’ privacy, disrupt the service, or attempt to abuse the cloud push relay (for example, relaying through it without a valid subscription). We may suspend access that abuses the relay.
The sidecar, the installer and this website are open source under the Apache License 2.0 and are governed by that license. These terms cover the mobile app and the hosted cloud push relay.
Kestrel is provided “as is,” without warranties of any kind. It is a tool for viewing and being notified about your own system; it is not a certified security or life-safety service, and cloud delivery is best-effort and can be delayed or dropped by third-party push networks. Do not rely on it as your sole safety mechanism.
To the maximum extent permitted by law, Pingnest is not liable for indirect, incidental, or consequential damages, or for any loss arising from missed, delayed, or undelivered notifications, or from your use of or inability to use Kestrel. Nothing here limits liability that cannot be limited by law.
We may update these terms; material changes will be reflected by the “last updated” date above and, where appropriate, noted in the app. Continued use after a change means you accept the updated terms.
