Tail Sniffer is free for verified aviation professionals and will stay that way. It runs on a small independent budget that covers ADS-B data, hosting, email delivery, and storage.
If the tool has been useful to you and you'd like to chip in, any contribution is genuinely appreciated. Zero pressure — the product is exactly the same whether you contribute or not. A contribution is voluntary support for the project and does not create a membership, subscription, guaranteed service level, priority support, or special access rights.
Payments are processed securely by Stripe. The Tail Sniffer never sees your card details.
Contributions are voluntary and non-refundable. They do not purchase premium monitoring rights, guaranteed alerts, priority treatment, or ownership over product decisions. Roxstar Labs is not a registered 501(c)(3), so contributions are not tax-deductible.
