Last updated 10 November 2026 · Flight Wiki is run by Nightingaley, Singapore · Contact info@nightingaley.com
Flight Wiki helps you search flight prices, watch them and map your trips. We collect as little as we can, never sell your data, and you can delete everything at any time.
What we store, and why
| Data | Why | Where |
|---|---|---|
| Google account name, email and photo (only if you sign in) | Your account; sending the price alerts you ask for | Google Firebase |
| Preferences, price watches, past trips you confirm | To save your setup across devices and check prices for you | Google Firebase (Singapore region) |
| Push notification token for your device | To send app notifications you turned on | Google Firebase |
| A random visitor ID, the pages you view and actions like searching or watching, and the website that sent you | Counting visitors and improving the app. No IP addresses or advertising IDs are stored. | Google Firebase |
If you don't sign in, your settings, watches and trips stay in your browser only.
Personalisation
Flight Wiki uses the routes you look at, watch and share here, and the hour you usually visit, to order your home page, suggest trips for you and time your price emails. It stays in Flight Wiki and your own account (in your browser only, if you are not signed in); nothing is sold or shared. Turn it off, or forget what it learned, under Account, Personalisation.
Services that process your requests
- Flight prices: the route, dates and cabin you search are sent to our flight data provider (SerpApi / Google Flights results, or Duffel) to get prices. No personal details are sent.
- Trip agent and price analysis: your question, and if you are signed in your preferences and watches, are sent to Anthropic (Claude) to write an answer. They are not used to train models.
- Email alerts: sent through Resend to your account email.
- Booking: links open airline and booking sites. What you do there is covered by their privacy policies. Some links (such as Trip.com and Expedia) are affiliate links: they carry our partner ID so we may earn a commission if you book, at no extra cost to you. No personal details are added to these links.
Importing past trips from Google (optional)
If you choose Gmail or Google Calendar on the My travels page, Google asks for read-only permission. Your emails and calendar events are read in your browser only to find flight bookings; they are never sent to or stored on our servers, and the access expires after about an hour. Only the trips you keep (from, to, date) are saved. The same applies to Google Timeline and calendar files you upload.
Flight Wiki's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Location
"Use my location" finds your nearest airport in your browser. Your location is not sent to us.
Keeping and deleting your data
We keep your account data until you delete it. Visitor counts are kept for up to 13 months.
Delete your account: in the app, open Settings → Delete my account. This permanently removes your account, preferences, watches, trips and notification tokens. Or email info@nightingaley.com from your account's email address and we will delete it within 30 days.
Children
Flight Wiki is not directed at children under 13 and we do not knowingly collect their data.
Changes
We will update this page if anything changes, and note the date at the top.
