Your privacy, in short

Arc Squads · Last updated: 30 August 2026

Arc Squads is for anyone aged 13 and over. This page answers the questions people actually ask about their information, in as few words as we can manage. Nothing here is dumbed down — it is the same truth as the full privacy policy, just faster to read.

If a single line of it annoys you or does not make sense, email hello@arcsquads.com and a real person will answer.

What do you know about me?

Less than most apps. Here is the lot.

What we have	Why we have it
Your email address	It is your account. We email you a 6-digit code to let you in. There is no password to forget.
Your handle — the name you pick	So your friends know which one is you.
Your date of birth	You type it in once when you sign up so we can check you are 13 or over. No one else using the app ever sees it.
Your arc — the rules you set, the day you started, and which days you ticked	It is the whole point of the app.
Any note you type on a check-in	Because you wrote it and you want it kept. Nobody in your squad can see it.
Your squad — which one you are in, and the embers you send	To show you your squad and pass on the encouragement.

We do not ask for your real name, your phone number, your address, or a photo. The app cannot open your camera or your photos at all. There are no adverts in Arc Squads, nothing follows you around the internet, and we do not build a profile of you or sell anything about you to anybody. Not ever. That is not a promise we are being generous about — the app simply has none of that stuff in it.

Things that stay on your phone and never reach us

Your weight goal — see below.
Your gym programme and the ticks you make against it.
Your step count, if you switch on Apple Health. The app only reads today's steps to show you a number. It is switched off unless you turn it on, it is never sent to us, and it never ticks a rule for you.
Your settings — dark or light, when your day starts, the order of your rules.
What time of day you usually tick. Your phone works that out by itself so reminders arrive at a sensible hour. It stays on the phone.

Who can see my check-ins?

Only the people in your squad, and only a thin slice of it.

Your squad can see:

your handle
which days you showed up — the date, and nothing else
the day your arc started
which weekdays are your rest days, so a rest day never looks like a fail
embers you send them

Your squad cannot see:

your email address or your date of birth
what your rules actually are
which rules you ticked on a given day — one or six, it looks the same to them
any note you wrote
your stats
your weight goal

Put simply: a friend can see that Tuesday counted. A friend cannot see what you did on Tuesday. And days you skipped or missed are not sent to us at all — only the days you tick leave your phone.

Leave a squad and the sharing stops from that moment.

Can you see my weight goal?

No. If you set a target weight, it stays on your phone. It is not sent to us, it is not shown to your squad, and there is no version of it on our computers for anyone to look at, leak, or hand over.

The catch is real and you should know it: because it only lives on that phone, it will not follow you to a new one.

We built it that way on purpose. Anything about your body deserves extra care, and the safest thing to do with information you do not need is to never collect it.

Who else gets my information?

A few companies help run the app. None of them are allowed to use your information for their own purposes, and none of them are advertisers.

Who	What they get
Supabase	Keeps the app's information safe on their computers — your email, handle, arc, check-ins and squad.
Resend	Your email address, so your 6-digit sign-in code arrives.
Apple	Only if you pay for something. Apple takes the money. We never see your card — or your parents' card.
RevenueCat	Checks whether you have paid. It gets your account number, which is a long string of letters and numbers, not your email or your handle.
Sentry	If the app crashes, it gets a note saying what broke, your phone model and your iOS version. We never attach your name, email or handle to it, and we have told Sentry not to record your IP address.
Expo	The tool we use to build the app. It gets nothing about you.
ImprovMX	Passes on emails you send to hello@arcsquads.com so they reach our inbox.

Your information is kept in the United Kingdom. Some of those companies work in the EU and the United States too.

Can I get rid of it all?

Yes, and you do not have to ask us first.

Take a copy first if you want one. Settings → Export hands you everything we hold about you as a file you can keep.
Then delete it. Settings → Account → Delete my account. It asks you twice, and then your account, your arc, your check-ins, your handle and your squad membership are gone from our computers. There is no undo, and there is no secret copy.
Or just clear this phone. Clear data on this device wipes the phone and leaves your account alone.

You can also email hello@arcsquads.com and we will do it for you. You can ask us to show you what we hold, fix anything that is wrong, or stop using it. Those are your rights in law, not favours. We aim to reply in a few days, and we have to reply within a month.

What if someone is horrible to me?

You have two buttons in the app, and you never need a reason to use either.

Block. They vanish from your view and you vanish from theirs. They are not told.
Report. This tells us. You pick a reason and you can add a short description of what happened. It comes to a real person, not a robot. We can take things down, pull someone out of a squad, or close their account for good.

When you report someone, we keep what you wrote and who you reported until we have dealt with it. We do not tell them it was you.

A squad is meant to be a small group of people you actually know. If someone in it is frightening you, or if anything you see makes you feel unsafe, please also tell an adult you trust. In an emergency in the UK, call 999. If you are struggling and want to talk to somebody who is not us, Samaritans are free on 116 123, any time of day or night.

How do I complain?

Email hello@arcsquads.com and say what we got wrong. Tell us plainly. We will try to put it right.

If we do not, you can go over our heads. The ICO — the Information Commissioner's Office — is the UK organisation whose job is checking that people like us handle your information properly. Complaining to them is free, and you are allowed to do it yourself at ico.org.uk.

You can ask a grown-up

You are allowed to want help with this. Show this page to a parent or carer and ask them what they reckon. If you would rather they emailed us instead of you, that is completely fine — write to hello@arcsquads.com and we will answer either of you. Asking is not a fuss and it does not annoy us.

Arc Squads is made by one person in Scotland. The email above is not a call centre. It is him.

The long version

Everything above is the short form. The full privacy policy has the detail — the legal reasons we are allowed to hold each thing, exactly where it is stored, and what happens if something ever goes wrong. The Terms of Use cover the rest: what is free, what costs money, and the rules for how to treat the people in your squad.
