Privacy policy

Last updated 2026-11-11

PartyXpense is provided by PartyXpense ("we"). This policy says what we collect when you use the PartyXpense app and this website, why, who else touches it, and what you can do about it. The short version: we collect what is needed to run parties and split costs between the people you choose, we do not sell personal information, and we do not show ads.

What we collect

  • Account. The email address or phone number you sign in with, the name you choose to display, an optional username, and an optional photo. If you set a security question, we store the question and a one-way hash of your answer.
  • What you put into parties and groups. Party details (name, date, place, description, background image), invitations and RSVPs, chat messages, polls and votes, lists of things to bring, itineraries, vendor notes, photos you post, and the expenses, receipts, pots and payments you record. People in the same party or group can see what you add there; that is the point of the app.
  • Payment handles. If you add a Venmo, PayPal, Cash App, UPI or similar handle, people you share a group with can see it so they can pay you. PartyXpense does not process payments and never sees your bank or card details.
  • Contacts, only on your device. If you allow it, the app compares phone numbers in your address book with PartyXpense accounts to find friends. Numbers are hashed on your phone before they are compared, and your address book is not uploaded or stored as a list.
  • Location, only when you use a feature that needs it. Suggesting places and showing public parties near you uses your location at that moment. If you turn on live location for a party, people in that party can see where you are until you turn it off or two hours pass. We do not track location in the background.
  • Calendar. If you ask the app to add a party to your calendar, it writes those entries. It does not read your other events.
  • Purchases. If you buy a pass or subscription, Apple or Google handles the payment. We receive a record that a purchase was made (product, date, an anonymous transaction id) so we can unlock what you bought. We do not receive your card number.
  • Notifications. A push token for your device, so we can deliver reminders you have not switched off.
  • Answers from an invite link. If you answer an invitation on this website without an account, we store the name you typed, your answer, how many people you are bringing, and a phone number or email only if you chose to give one. The party's hosts can see these. A random key is kept in your browser so you can change your answer.
  • Tickets, check-in and booths. If you are going to a party you get a ticket code, shown as a QR code. When a host scans it we record that you arrived and when, so hosts can see who has checked in. For an event with a price we also record that the host confirmed your payment at the door, and the amount. If your ticket is scanned at a vendor's booth we record that visit; the vendor sees your first name and how many people are with you, and a count of visits, never your contact details.
  • Hosts of public events. When a host accepts the public event terms we record their account, the party, the version of the terms and the time, and we keep that record after the party or the account is deleted, for as long as we may need it to deal with a legal claim.
  • Anonymous usage data. Unless you switch it off in the app (You, then App), the app sends which screens are opened, how long they stay open, and short codes for errors and unfinished forms. It includes your device's country and time zone setting and an age range only if you chose one. It carries no account, name, party, message or amount, and it is not linked to you. A random code that changes each time the app starts groups events from one session.
  • Technical logs. Our hosting providers keep standard server logs (IP address, time, request) for security and troubleshooting.

How we use it

  • To run the service: showing your parties to the people in them, delivering messages and reminders, and working out who owes whom.
  • To keep it safe: rate limits, abuse reports and blocks, and investigating misuse.
  • To improve it: the anonymous usage data above tells us which screens confuse people.
  • To unlock purchases and answer support requests.

We do not sell or rent personal information, and we do not use it for advertising.

The assistant and receipt scanning

If you use the in-app assistant, translate a message, or scan a receipt, the text or image you submit is sent to an AI model provider to produce the result. It is sent for that request only. Do not put information in an assistant request that you would not want processed this way. Vendor searches are sent to a web search provider without your identity.

Who else processes data for us

  • Supabase: database, sign-in, file storage and server functions.
  • Apple and Google: push notifications and in-app purchases.
  • RevenueCat: purchase records, once purchases are enabled.
  • Vercel: hosting for this website, and page-speed measurement on its home, help, privacy and terms pages (how fast the page loaded, the kind of device and browser, the country; no cookies, and nothing that identifies you). Invitation and booth pages are not measured.
  • An AI model provider and a web search provider for the assistant features described above, and an SMS provider for sign-in codes if you use a phone number.
  • Map and place suggestions come from OpenStreetMap-based services, which receive the text you type and an approximate location.

We may also disclose information if the law requires it, or to protect someone's safety.

What other people can see

  • People in a party or group see what you post there and your display name and photo.
  • Your email and phone number are not shown to other members, with one exception: when a host or co-host of a party you are going to scans your ticket at the door, they see your name, how many people you are bringing, and your phone number and email, so they can confirm it is you. Someone who already knows your exact username, email or phone can find your profile unless you switch that off in the app.
  • Invite pages on this website show the party, its host's name and how many people are coming. They never show guest names, chat or money. Hosts can hide the guest count.
  • Public parties appear to anyone browsing the app with their city, date and price. The street address is shared only with guests the host accepts.

How long we keep it

  • Your account and what you added stay until you delete them or your account.
  • Deleting your account removes your profile, sign-in details and device tokens. Expenses and messages you added to shared groups remain for the other people in those groups, shown without your contact details, because they are part of their records too.
  • Vendor contact details are removed 180 days after an event ends. Read-only itinerary links stop working 30 days after the event.
  • Anonymous usage data is deleted after about 13 months.
  • Answers given from an invite link are deleted with the party, or sooner if a host removes them.

Your choices and rights

  • See and change your profile in the app. Delete your account in the app: You, then Account, then Delete account.
  • Switch off notifications, contact matching, location, calendar access and anonymous usage data at any time, in the app or in your phone's settings.
  • Ask us for a copy of your data, to correct it, or to delete it, by writing to calculatehq@gmail.com. Depending on where you live (for example the EU, UK or California) you may have further rights, including to object to processing or to complain to your data protection authority. We will not treat you differently for using these rights.

Children

PartyXpense is not directed to children under 13 (or the age required in your country), and we do not knowingly collect their personal information. If you believe a child has given us information, write to calculatehq@gmail.com and we will delete it.

Security

Data is encrypted in transit. Access to each party and group is enforced on the server so that only its members can read it, and files are stored privately except invite backgrounds, which are public so that invitations can show them. No system is perfectly secure; if we learn of a breach affecting you we will tell you as the law requires.

International use

Our providers may store and process data in the United States and other countries, which may have different data protection rules from yours.

Changes

If we change this policy in a way that matters, we will say so in the app or on this page before the change takes effect.
