The fine print
Privacy policy
What we collect, how the AI assistant uses it, who else sees it, and how to delete it.
last updated 1 october 2026 · applies to sharetravel.app and the share app
01
What we collect
Your account. Your phone number, first and last name, date of birth, and, if you add one, your email address.
Your trips. The trips you take part in, the messages you send in trip chats, your votes and picks, the plans you build, and any links you share into Share.
Bookings and payments. The traveler details a booking needs (name, date of birth, title, email, and phone number), the bookings you make, what you have paid, and any record of what you owe or are owed by people on your trips.
Travel details, only if you add them. Your home airport, travel style, pace, preferred climate, accommodation and dining preferences, dietary needs, TSA PreCheck number, passport country and expiry date, and airline and hotel loyalty program numbers. Dietary needs can reveal religious beliefs or health information. We use these details to tailor what Share suggests, and you can change or clear them in Profile at any time.
Your device. A push notification token so we can send you notifications, and a record of which device signed in.
People you invite.When you add someone to a trip, you can type their number or choose them with your phone's contact picker. The app only sees the one contact you choose and never reads your address book. We receive that person's phone number, not their name. If they are not on Share yet, we keep the number with the invitation and send them a text message through Twilio with your name, the trip's name, and a link to join.
Support. What you send us when you email us or report content.
The website. If you join the waitlist, the email address and phone number you submit, optionally your first name, and how you reached the site.
02
What we do not collect
We never see or store full payment card numbers. Card details go directly to Stripe, and we keep only a token plus the card brand and last four digits.
We do not collect your device's location. We do not sell your personal information, share it with advertisers, or use it to track you across other companies' apps and websites.
03
How we use it
To run Share: signing you in, showing your trips to the people on them, suggesting plans, searching for and booking travel, taking payment, sending booking confirmations and notifications, and keeping track of who owes whom.
To keep Share safe: verifying phone numbers, preventing fraud and abuse, and reviewing reports of objectionable content.
Waitlist emails are used only to send you an invite and occasional updates. Every email includes a way to unsubscribe. Your waitlist phone number is used only so Share can message you on iMessage. Reply stop and it stops.
04
The AI assistant
Share's assistant is powered by third party AI models, provided by Anthropic and, as a fallback, OpenAI. When someone in a trip asks the assistant something, by mentioning it, replying to it, or answering one of its questions, we send it what it needs to answer: recent messages in that trip, the full names of the people on it, the home airport of each member who has added one, and the trip's details and plans, such as dates, budget, availability, and the places being discussed. In a trip where you are the only member, every message you send is treated as a message to the assistant.
When you save or share a link into Share, we send the link, its title and description, and anything you typed with it to the AI model to work out which place it is about.
These providers process this data to generate the assistant's replies on our behalf, under their commercial terms, which do not allow them to use it to train their models.
05
Who sees your information
People on your trips see your name, your messages, your votes and picks, and the bookings you share with the group.
Service providers receive only the data needed to do their job for us: Twilio (verification texts), Stripe (payments), Duffel (flights and stays, including the traveler details the airline or hotel needs), Anthropic and OpenAI (the AI assistant), Resend (email), Apple and Expo (push notifications), Google (maps), OpenStreetMap (finding places by name), and our hosting providers, Railway and Vercel.
Travel providerssuch as airlines and hotels receive the traveler details a booking needs. If you tap through to Viator to book an experience, you leave Share and Viator's privacy policy applies to what you give them there.
When the law requires it, or to protect the safety of our users or the public, we may disclose information to authorities.
06
Keeping and deleting your information
We keep your information while your account is open. You can delete your account at any time from Profile in the app. When you do, we:
- remove your name, phone number, date of birth, and email address from your account;
- delete your travel details, loyalty program numbers, saved links, friends list, notification settings, and any invitations you sent that nobody has accepted;
- delete your saved cards at Stripe;
- remove your availability and home airport from the plans of the trips you were on;
- and sign you out on every device.
Messages, votes, and picks you made in a trip stay visible to its other members, shown as coming from a deleted user. Reports you filed, and reports filed about you, are kept so we can keep Share safe.
We keep records of bookings and payments for as long as we need them for tax, accounting, dispute, and other legal obligations, even after you delete your account.
To delete a waitlist entry, or for any other request about your data, email hello@sharetravel.app.
07
Security
Information is encrypted in transit, sign in uses one time codes sent to your phone, and access to production data is limited to the people who need it to run Share. No system is perfectly secure, so please tell us at hello@sharetravel.app if you think something is wrong.
08
Age and region
Share is for people aged 18 and over, and we do not knowingly collect information from anyone younger. Share is currently offered in the United States only.
09
Changes to this policy
If we change how we handle your information, we will update this page and its date. For a material change, we will also let you know in the app or by email before it takes effect.
