Privacy policy
Kaviqa collects the information needed to run accounts, subscriptions, saved preferences, flight research, and — where Kaviqa booking is available and you complete a purchase through it, acting as your booking agent through Duffel — the booking itself.
This includes account email, authentication identifiers, saved routes, airline preferences, search inputs, billing customer identifiers, and operational logs needed to diagnose searches and keep the service reliable. If you book a flight through Kaviqa, it also includes passenger details entered for that booking: full name, date of birth, contact details, and, where the airline requires it for the fare, passport or other identity document details.
Payments
Payments (subscriptions, and flight tickets bought through Kaviqa) are processed by Stripe. Kaviqa stores Stripe customer and subscription identifiers and, for a flight booking, the payment amount and card brand/last four digits Stripe reports back — never full card numbers.
Service providers
Kaviqa uses the following providers to run the service. Each processes data under its own terms and policies. Some of them store or process information outside Australia.
- Cloudflare — account, database, and authentication storage, including account sessions and Google sign-in when you choose it.
- Supabase — retained read-only historical data and a recovery copy from Kaviqa’s previous account, database, and authentication storage.
- Stripe — subscription and flight-ticket payment processing.
- Duffel — when you book a flight through Kaviqa, Duffel is the platform Kaviqa uses to place and manage that order with the airline; it receives the passenger and booking details needed to issue the ticket.
- Kiwi — fare search for some results. If a result sends you to Kiwi to complete a booking, the details you enter there go directly to Kiwi, not through Kaviqa.
- Awin — the affiliate network behind Kaviqa’s Kiwi links. Following a Kiwi link passes through an Awin tracking link, which records the click and any resulting Kiwi booking so Kaviqa can earn a commission. Kaviqa does not send Awin your name, email address or passenger details.
- Google — Google Flights pages for some live fare research (search details, not passenger identity), and Google sign-in if you use it to log in.
- DeepSeek — an AI model Kaviqa uses for some route planning. It only ever receives search details (route, dates, cabin); Kaviqa does not send it passenger identity or payment information.
- Resend — sends booking confirmation, receipt, and status emails, which include your booking details and passenger names. It also sends the confirmation and deal emails you ask for under Deal emails.
- PostHog — product analytics (pages viewed, search usage), tied to an anonymous identifier rather than your name. See Cookies and similar technologies for when it runs. If you have agreed to deal emails, Kaviqa also uses that activity (for example the deals you open and the routes you search) to choose which deals to email you; see Deal emails.
- Meta — advertising measurement (Meta Pixel and Conversions API) on public pages and for new memberships. See Cookies and similar technologies for when it runs and what it receives.
- Vercel and Railway — hosting for Kaviqa’s website and search/booking backend; all traffic and stored data passes through their infrastructure.
Trip booking requests
If you send a request on the “We book it for you” page, Kaviqa uses what you enter (your name, email address, where you want to go and, if you say, when, plus anything else you choose to write about the trip) and the campaign tags in the page’s address, only to contact you about that trip. Anything you tell us about who is travelling, such as family or accessibility details, is used only to plan the trip. The request is emailed to our team through Resend, and is not stored in our website database; the email is the record. We email you a confirmation that contains none of the details you entered, and to stop repeat confirmation emails we hold a one-way hash of your email address for 24 hours (the address itself is not kept for this).
Who sees it, and for how long. Only the Kaviqa team reads request emails. They are kept only as long as needed to plan and support your trip, and are deleted after your trip or within 12 months of your request, whichever comes first. You can ask support to delete yours sooner.
If you have agreed to analytics cookies, Kaviqa also counts that a request was sent. That count carries no name, email address or trip details.
Deal emails
If you use “Email me deals” on the Best deals pages, Kaviqa stores your email address, the departure city you chose, the page you signed up on, any campaign tags in that page’s address (utm_source and similar), the date and the wording you agreed to, and a hashed copy of a private link code. Kaviqa does not store your IP address with the sign-up.
What we send. First one email with a link to confirm your address. Until you tap it, you are not subscribed and nothing else is sent. After that, occasional emails with the best deals from the city you chose. These are marketing emails; they are separate from the booking and account emails above, and you do not need to subscribe to book or to use Kaviqa. If you gave your email address in a sign-up box that said we would also email you occasional deals, we send those deal emails only once you have confirmed the address by creating your Kaviqa account from the link in the email we sent you; an address nobody has confirmed gets no deal emails. If you asked us to watch a route and confirmed it, the occasional deal email is part of what you agreed to, for as long as that watch is on. Kaviqa members may also get them. You can stop them at any time.
How we choose which deals. When you have agreed to deal emails, we use your activity on Kaviqa to choose which deals to email you. That means the deals you open and tap, the routes you search, and the departure city you chose. It is only counted while analytics is allowed for you (see Cookies and similar technologies). Kaviqa links the analytics ID of your browser, or of your account, to your email address, builds a short summary of your interests (such as the places and cabin you look at), and sends an email when a new deal fits it, when a deal you opened has ended, or the day after you searched a route and left. We send you at most one such email every two days and three a week, and not between 9 pm and 7 am Sydney time. We delete the summary within a day of you unsubscribing. Prices in these emails are what we saw at the time shown, not a live quote.
How to stop. Every deal email has an unsubscribe link, and mail apps that support it show their own Unsubscribe button. Either takes effect at once, with no login. You can also email support@kaviqa.com. After you unsubscribe we keep the address and the unsubscribe date so we do not email you again by mistake. A sign-up through the “Email me deals” form that you never confirmed is not used for anything, other than the advertising measurement described next.
Advertising measurement. Where advertising measurement is allowed for you (see Cookies and similar technologies), Kaviqa tells Meta that a sign-up happened, with a one-way hash of your email address and your IP address so Meta can match it to the ad that led you here. Meta is told when you give your address, whether or not you later confirm it. If you have declined, nothing is sent. If you have not chosen, nothing is sent until you press Allow in the places that need your permission first; elsewhere it is sent unless your browser sends Global Privacy Control. Pressing Allow overrides Global Privacy Control.
