Privacy Policy
Stamped keeps your trips on your device unless you share them. No tracking, no ads, and an account only if you want to share. Documents you add are read by Claude, Anthropic’s AI, only once you allow it, aren’t kept, and are never shared. It sends anonymous install and usage counts, and you can turn them off.
On your device
Besides your trips, the app saves only its own settings, such as your passport country and whether reminders are on. We can’t see them, and deleting the app removes them.
Your trips and documents
The screenshots, photos and PDFs you add, and the trips read from them, are kept on your device, encrypted while your iPhone is locked. Profile → Delete All Trips removes them, as does deleting the app.
Before the first document is read, the app asks whether it may send your documents to Claude. Until you say yes, nothing is sent; you can change your answer any time in Profile → Read Documents with Claude.
To read a document, the app sends it over an encrypted connection to our reading service, which passes it to Anthropic’s Claude and returns the bookings it finds. Our service doesn’t store the document or what was read from it, and logs only that a request was made. Anthropic processes it under its commercial terms: it isn’t used to train models and is deleted after a short retention period. Only the documents you choose are sent, one at a time.
Trip names, photos and flight status
To name a trip and show a photo of where it goes, the app sends only the places, the month and the trip’s length to our service, which asks Claude for a name and Unsplash for a photo. On the day of a flight, it sends only the flight number, date and departure airport to our service, which asks AeroDataBox where the flight is at. Nothing about you goes with them, and answers are shared between everyone asking about the same place or flight.
When a hotel booking comes without an address, the app looks the hotel’s name and city up in Apple Maps, on your device, so the address is there for arrival forms. Apple’s privacy policy covers that search.
Sharing trips
Sharing is optional. To share a trip or join a friend’s, you sign in with Apple. We receive an identifier Apple makes for Stamped alone and, the first time only, the name you choose to share; we never see your Apple password, and you can hide your email from us entirely, since we don’t ask for it.
When you share a trip, its name, the city its photo is of and its bookings (flights, stays, trains and so on, with their times, references, travellers and prices) are stored on our service so the people you invite can see them. Your visas, passport, insurance and the files bookings were read from are never shared. Anyone with an invite link can open the trip; with a view-only link, they can’t change it. The web page a link opens for people without the app shows only the plan, without references, names or prices. The picture a link shows in Messages and other apps has the trip’s name, dates, cities and the first names of the people in it.
Stop sharing a trip and it’s deleted from our service for everyone. Leave a friend’s trip and the bookings you added go with you. Profile → Delete Account deletes your account and everything you shared, straight away.
Anonymous usage counts
So we know how many people use Stamped and which parts they use, it sends two small messages to our server: one when it’s first installed, and at most one a day while it’s in use. Each says whether it’s the iPhone or Mac app, whether it came from the App Store or TestFlight, and which versions of the app and of iOS or macOS you run. The daily one also carries totals of what was done since the last, such as how many documents were added or trips opened, and the names of the features you have on, such as reminders. Our server notes the country the message came from and keeps no IP address, and stores the totals apart from the country. There is no identifier, so we can count installs but never tell who or which device. Nothing from your trips or documents is ever sent: no names, places, dates or references.
To stop them, turn off Share Usage Counts in Profile.

If you share analytics with developers, Apple may send us anonymous crash reports. Downloads are handled by Apple; we never see payment details.
If you email us, we use your address only to reply.
