SplitWithUs

Privacy policy

Last updated November 9, 2026

SplitWithUs has five calculators, for trip expenses, for a trip with a guest of honor, for restaurant and bar bills, for roommates moving out, and for the fuel on a road trip, and all of them run in your browser. This policy explains what data exists when you use it, where it goes, and how long it stays. In short: the settlement you enter stays on your device unless you choose to create a share link, and the site shows Google ads, which use cookies.

What you enter

Trip names, people's names or nicknames, receipts, amounts, currencies and dates are processed in your browser. They are not sent to our server while you work. We do not ask for an email address, an account, or real names; nicknames work just as well.

Share links

When you press "Share to the group chat", the settlement is stored on our server so the link can be short. What is stored: the trip name, the names you entered, each receipt (title, kind, amount, currency, date, who paid, who shared it, home currencies), the day of the newest reference rate when the link was made, and the exchange rates the settlement used (one rate per currency for each day a receipt was paid). For a trip with a guest of honor it also stores who the guests of honor are, which kinds of receipt the group treats them to, and any receipt you switched. For a restaurant or bar bill it is the names, the currency, and for each place its name, who was there, each item (name, price, how many, who had it), discount, service charge, tax, tip, who paid and the receipt total if you entered one. For a move-out it is the names, the currency, the settling-up day, each person's move-in and move-out days and room rent if entered, each bill (name, kind, amount, whether it is an estimate, real amount if entered, the days it covers, who paid, how it is split), what each person put into the deposit and each deduction (what, amount, shared space or whose room) with who gets it back, and each shared item (name, price, day bought, years it lasts, owners, agreed value and what happens to it). For a road trip it is the names, the currency, miles or kilometers, the driver relief setting, each leg (name, distance if entered, who rode, who drove), each fuel line (name, who paid, the leg, and either the amount or the distance, fuel efficiency and price used to estimate it) and each toll or parking line (name, amount, who paid, who shared it). It is stored with a random ten-character id and nothing else: no IP address, no cookie, no account. The data sits in Cloudflare D1, a database run by our hosting provider.

  • Anyone who has the link can open the settlement. Share it only with the people it concerns, and do not put sensitive details in receipt titles or item names.
  • Stored settlements are deleted automatically 365 days after they were created.
  • To delete one earlier, email us the link at [email protected].
  • If the share service cannot be reached, the link carries the settlement itself after the "#" sign instead. Browsers do not send that part of a web address to our server, and pages that open a shared link load no ads, so it is not passed to an ad network either.

Storage in your browser

We do not set cookies of our own. The calculator uses your browser's storage for convenience only:

  • sessionStorage keeps the trip you are working on for the current tab, and is cleared when the tab closes. The trip page and the guest of honor page each keep their own.
  • localStorage keeps your last issued settlement on this device, one for each of those two pages, so you can reopen it later. The "Forget it" button, or clearing your browser's site data, removes it.
  • localStorage also keeps the restaurant night you are working on, so you can finish it the next day. "Start a new night", or clearing your browser's site data, removes it.
  • localStorage also keeps the move-out you are working on, so you can come back when the last bill arrives. "Start over", or clearing your browser's site data, removes it.
  • localStorage also keeps the road trip you are working on, so you can finish it later. "Start over", or clearing your browser's site data, removes it.
  • localStorage also remembers that the short opening scene on the trip calculator has played, so it starts folded on your next visit. Clearing your browser's site data resets it.

Exchange rates are downloaded from this site. Your browser does not contact any rate provider.

Advertising and cookies

This site shows ads served by Google AdSense, except on pages that open a shared link (addresses starting with /s): an ad request includes the full page address, and there the address carries the settlement or its link id. The page-not-found, contact, terms and editorial policy pages load no ads either. Google and its partners use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on those visits. You can opt out of personalised advertising in Google Ads Settings (adssettings.google.com), and opt out of some third-party vendors' use of cookies at aboutads.info. Google explains how it uses information from sites that show its ads at policies.google.com/technologies/partner-sites.

Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent through a Google-certified consent message before personalised ads are shown. Visitors in US states with privacy laws can limit how their data is used for ads through the same Google settings.

Services that receive technical data

  • Cloudflare hosts the site. Like any web host it receives your IP address and browser details to deliver pages and block abuse. See the Cloudflare privacy policy.
  • Cloudflare Web Analytics counts page views and visits so we can see how busy the site is. It works without cookies, does not fingerprint your device, and does not follow you to other sites. See Cloudflare Web Analytics.
  • Google AdSense, as described above.

When a calculation is finished, the page adds one to a daily count of which tool was used and a rough source of the visit (for example "search", "direct" or the name of an AI assistant). Nothing you entered, no name, amount or address, is part of it.

We do not sell personal information, and we do not use analytics that follow you across sites.

Do Not Track

There is no common standard for how websites should respond to a browser's Do Not Track signal, so this site does not change its behaviour when it receives one. Our own pages do not track you. Google's advertising follows its own policies and the ad choices described above.

Children

SplitWithUs is not directed at children under 13, and we do not knowingly collect information from them.

Changes and contact

If this policy changes, the date at the top changes with it. Questions or requests: [email protected].
