Delete your data — Splitmate

Splitmate is an Android app for splitting bills with friends, made by Quizuncle, and currently given out through a Google Play closed test. This page sets out every way to delete the data it holds. It is written so that you can follow it whether or not you have the app in front of you.

There are four routes, and they remove different amounts. They are listed cheapest first. If you want the short answer: emailing us is the only route that erases data from our server, and everything above it removes less than that. There is a table at the end showing which route removes what.

Two things to know first

1. Email us before you clear the app’s data, not after. Splitmate has no login: no email address, no password, no phone number and no user directory. The only thing that identifies your copy of the app is an anonymous identity generated when you first installed it, and that identity is stored inside the app’s own data. Once you clear that data or uninstall the app, it is gone from your phone, and we may have no way left to work out which entries in the database were yours.

2. Expenses you logged as Just me cannot be recovered. They were never uploaded anywhere, so there is no copy of them to restore. Clearing the app’s data or uninstalling the app destroys them permanently. That is the same fact stated twice: nobody else can ever see them, and nobody can ever get them back for you.

Route 1 — Remove everything on your phone

You do not need the app open, and you do not need us.

To wipe the data and keep the app: open Android Settings → Apps → Splitmate → Storage & cache → Clear storage. On some phones the last two steps are called Storage and Clear data.
To remove the app as well: press and hold the Splitmate icon, choose App info, then Uninstall. Uninstalling clears the data on the way out.

This removes, from that phone:

every expense you logged as Just me, permanently and with no copy anywhere;
the local copy of every group you are in, with its members, expenses, settlements and chat history;
your display name, your profile picture and every app setting;
any invite code the app had stored for a group you shared;
the anonymous identity this installation was using, and with it the phone’s way back into any group it had joined.

This removes nothing from the server. Specifically, it leaves behind:

your display name, avatar colour and profile picture in every group you were in — the other members still see them;
every expense and settlement you added to a group, and every message you sent;
the entry recording that your identity was a member of each of those groups.

If you signed in with Google before doing this, reinstalling the app and signing in again brings your groups and chats back, because the identity comes back with the sign-in. Your Just-me expenses do not come back, because they were never sent anywhere to come back from.

Route 2 — Remove entries inside the app

Two things inside a group can be removed by anyone in it, and both of them travel to everybody else’s phone.

Removing a member

Open the group, open its member list, and use Remove beside the person. The app asks you to confirm first.

There is one thing it will not let you do. Once you have marked which member of a group is you, your own row carries no Remove button — taking yourself out of a group is not an action the app offers, and there is nowhere else in it that does. If that is what you want, it is an email request; see route 4.

Removing somebody takes them out of the balances and stops them being included in new splits. That is the whole of it, and the rest is worth spelling out because it is easy to assume otherwise:

It does not reach their phone. The device they joined the group on keeps the copy it already has, and goes on receiving the group’s updates and its chat.
Their display name, avatar colour and profile picture stay in the group’s records on the server, marked as removed rather than erased.
Their share of past expenses stays exactly where it is, along with every expense and settlement they added. It has to: the group’s history would stop adding up without it.

Deleting an expense

Deleting an expense takes it out of the balances and hides it from every member. The record underneath — its description, its amount and its note — stays on the server behind a marker that says it was deleted. That marker is what carries the deletion to everyone else’s phone, which is why it cannot simply vanish.

There is no “leave group” button, and no way to delete a whole group from inside the app. Nothing in the app ends your own device’s membership on the server, and nothing in it removes a group’s records. If either of those is what you want, it is an email request — see route 4.

Route 3 — Delete your chat messages

Press and hold your own message in a chat and choose Delete for everyone. The option only appears on a message you sent, and only while it has not already been deleted.

This is the one action in the app that erases content from the server. The text is removed — not hidden, not flagged — for every participant, and their copies update as soon as their phones connect.

What stays behind is an empty marker: the message’s id, who sent it, and when. It has to stay, so that the deletion reaches a phone that was offline at the time and so that the conversation does not renumber itself for everybody else. The marker carries none of what you wrote.

Two things it cannot reach. A notification already delivered to somebody’s phone carries the text of the message, and deleting the message afterwards does not recall it. And anything anyone copied or captured on their own screen is theirs, not ours.

Messages other people sent are theirs to delete, because only a sender can delete their own message. Ask them, or ask us at route 4.

Route 4 — Ask us to erase your data from the server

Email splitmate@quizuncle.com with the subject Delete my Splitmate data. A person reads it; there is no form and no account to sign into.

What to put in the email

Because Splitmate has no login, the hard part is matching your request to the right rows. Help us do that:

Your Splitmate ID, if your version of the app has one. Open Settings and look for a Copy my Splitmate ID row; if it is there, tap it and paste the value into the email. This is the most reliable thing you can send, and on its own it is enough.
If your version has no such row, tell us instead: the name of each group you want your data removed from, the display name you used in it, and roughly when you joined. If you still have a group’s invite code, include that as well — it identifies the group exactly.
What you want removed — your own details only, or everything in a group that can be traced to you.
If you signed in with Google, say so and give the address, so we can find the sign-in record too.

Please send this before you clear the app’s data. Once the app’s data is gone, your Splitmate ID is gone with it, and a description of a group may be all either of us has left to go on.

What we remove

your member entry in each group you name, with the display name, the avatar colour and the profile picture in it;
the entries that record your device’s membership of those groups, and your own private index of which groups you are in;
your notification token, so that phone stops being addressable;
the text of chat messages you sent, and your entry in each conversation;
your Firebase sign-in record, including the Google email address, the name and the link to the profile picture held against it, if you used the optional Google sign-in;
the whole group, its chat and its invite code, where you are its only member — or where every member of it asks us together.

What we will not or cannot remove

Expenses and settlements in a shared group, at one member’s request. A bill you paid is what tells the other members what they owe; deleting it would silently change their balances and their history. Those rows are as much their record as yours, so we will not delete them on one person’s say-so. If the group agrees, we will remove the group entirely.
Messages other people wrote. Those are theirs, on the same reasoning.
Anything already on somebody else’s phone. Every member’s device keeps its own copy of the group it belongs to. We can delete the server’s copy; we cannot reach into another person’s phone, and neither can the app.
A notification that has already been delivered, or anything anybody saved, copied or captured on their own screen.

How long we take

We reply within 7 days to confirm what we have been able to match, and complete the deletion within 30 days of that confirmation. We will tell you what was removed and what was not, and why. The only reason we will come back with a question is that we could not identify your data from what you sent.

Which route removes what

Every kind of data Splitmate holds, and what removes it. “On your phone” means the copy in the app’s private storage on your own device; “on the server” means the copy in the Google database that members of a group share. The privacy policy lists exactly what is in each.

Data	On your phone	On the server
Expenses you logged as Just me	Route 1	Never sent there
App settings: theme, currency, your name	Route 1	Never sent there
Your display name in a group	Route 1	Route 4
Your profile picture and avatar colour	Route 1	Route 4
Whether you appear in a group’s balances and new splits	Route 2	Route 2
Expenses and settlements you added to a group	Route 1 removes your copy	Route 4, and only with the group’s agreement
Chat messages you sent	Route 1 removes your copy	Route 3, or Route 4
Chat messages other people sent	Route 1 removes your copy	Their own Route 3, or Route 4 with the group’s agreement
Your anonymous Splitmate identity, and its membership of a group	Route 1	Route 4
Your notification token	Route 1	Route 4, or automatically once Google reports the phone unreachable
Your Google email and profile details, if you signed in	Route 1 ends the session	Route 4
A group’s invite code, and the whole group	Route 1 removes your copy	Route 4, if you are the only member or the group asks together
Your email address, if you used the notify form on this website	The app never has it	Email us — see the notify list. Deleted after the launch either way.

This website

This site keeps one cookie, qu_theme, holding the word dark or light so the page matches the theme you picked. It is not an identifier and nothing tracks you here. Clearing your cookies removes it — see the privacy policy.

The notify list

There is one form on this site: the box on the home page for being told when Splitmate has a public release. If you used it, we hold the email address you typed, the moment it arrived, and a short label recording which form it came from. Nothing else — no IP address, no browser details, no cookie — and it is not connected to any Splitmate install or to any group.

To come off it, email splitmate@quizuncle.com and say so. Send it from the address you gave us, or tell us what that address was; there is no identity to match here, so this is the quickest request on the page and we remove the whole record.

It also goes without you asking. The list exists for one announcement, after which everyone who does not say they want to stay on it is deleted — the privacy policy states that in full.
