The short version. We collect only what's needed to send you The Four newsletter and, in the app, to search flights. FourFlights never takes your payment and never asks for passport or card details — when you book, you do it on a trusted partner's site. We don't sell your data and we don't show ads.
This policy covers the FourFlights website and newsletter ("The Four") and the FourFlights iOS app ("FourFlights," "we," "us"). By using them you agree to this policy.
The Four newsletter
Your email address. When you subscribe, we store your email with MailerLite, our email service provider, and use it for one thing: sending you The Four. Unsubscribe with one click in any edition and we stop; you can also ask us to delete your address entirely.
Replies. If you reply to an edition, your message goes to Peter's inbox and is used only to answer you and improve the newsletter.
Affiliate links. Some flight links in the newsletter and on this site are affiliate links (via Travelpayouts/Aviasales). If you book through one, we may earn a small commission at no cost to you — it never changes your price.
The app: information we collect
Search details. The origin, destination, dates, and number of travelers you enter, so we can find flights for you.
App-integrity data. We use Apple's App Attest to confirm requests come from a genuine, untampered copy of the app. This helps prevent fraud and does not identify you personally.
Limited on-device data. Some non-sensitive preferences (for example, recent searches) may be stored locally on your device to improve your experience. We do not collect or store your payment, passport, or travel-document details — we never ask for them.
Booking happens with our partner. The app shows you flights but does not sell tickets or take payment. When you choose to book, we send you to a trusted booking partner, and any details you enter — traveler information, payment — are provided to them and handled under their privacy policy, not ours.
How we use your information
To send you The Four, if you subscribed.
To search for flights and show you results and prices.
To provide customer support and respond to your messages.
To detect and prevent fraud and keep the service secure.
To meet legal and accounting requirements.
How your information is shared
We share information only as needed to provide the service: with MailerLite to deliver the newsletter; with Apple for app-integrity checks; with our booking partner only when you choose to visit their site to book; and when required by law or to protect our rights and users' safety.
We do not sell or rent your personal information, and we do not use it for advertising.
Data retention
We keep newsletter addresses until you unsubscribe or ask us to delete them. We don't keep booking or payment records, because booking happens on our partner's site. We minimize the personal information we store.
Your choices and rights
You can contact us to access, correct, or delete the personal information we hold about you. Depending on where you live (for example, under GDPR in Europe or the CCPA in California), you may have additional rights over your data. To make a request, email support@fourflights.app.
Children
FourFlights is not directed to children, and we do not knowingly collect personal information from children under 16. If you believe a child has provided us information, contact us and we will delete it.
Security
We never collect your card or passport details, requests to our servers are verified with Apple App Attest, and we deliberately minimize the personal data we store. No method of transmission or storage is 100% secure, but we work to protect your information.
Changes to this policy
We may update this policy from time to time. We will post the updated version here and change the date at the top.
