MyCache is a family savings app. Parents keep a savings account for their children, balances earn interest, allowances post automatically, and kids can check in from the web, an iPhone, an iPad, or an Apple Watch.
Getting started
How do I set up a family? Download MyCache and create an account. You'll be the first parent, and you can invite the rest of your family from the Family tab.
How do I add my child? Open the Family tab and choose Add someone. If your child has an email address, they'll get an invitation to sign in with. If they don't, MyCache gives you a sign-in code to read out to them instead — children don't need an email address to use the app.
My child doesn't have a phone. Can they still use it? Yes. They can sign in on any device, including a shared family iPad or a web browser, using the code you give them.
Signing in
I've forgotten my password. Tap Forgot password? on the sign-in screen and we'll email you a link. It's valid for one hour.
I didn't get the email. Check your spam folder first. If it still hasn't arrived, email support@arc3ventures.com and we'll help.
It says my email isn't confirmed. We send a confirmation email when you sign up, containing a six-digit code and a link — either one works. It's valid for 24 hours. If yours has expired, choose Resend on the sign-in screen to get a new one.
My child's sign-in code doesn't work. Codes are single-use. A parent can create a fresh one from the Family tab, under the child's name.
Money, interest, and allowances
Is this real money? No. MyCache keeps a record of money you already owe your child — pocket money, birthday money, chores. No real funds move, and MyCache is not connected to any bank, card, or payment service. Paying your child is still something you do yourself.
When is interest added? On the first of each month. You choose the rate, and you can change it whenever you like — past months keep the rate that applied at the time.
Can I backdate a deposit? Yes. Deposits and withdrawals can be dated in the past, as far back as your child's birthday, and MyCache recalculates the balance and all the interest that follows.
What happens if the balance goes below zero? Nothing breaks — a balance can go negative. No interest is charged on an overdrawn account.
Can I change the currency? Yes, in Family settings. The currency is the symbol your family's money is shown in; it doesn't convert any amounts.
Requests and goals
How does my child ask to spend? From the Requests tab. You'll get a notification, and you can approve or decline, with a note if you'd like to explain. Nothing leaves the account without a parent approving it.
What are goals? Things your child is saving for. MyCache shows how close they are and what spending the money today would really cost once you count the interest they'd give up.
What are coins? Small awards for saving habits — a first interest payment, a year without a withdrawal. They're earned, never bought, and nothing in MyCache is for sale.
Privacy and your data
What do you store? Your family's names, email addresses where you've given them, and the savings records you enter. Nothing more. We don't use advertising, analytics, or tracking services, and we never sell data.
Full details are in our Privacy Notice and Terms of Use.
How do I delete my account? In the app, open your profile from your picture in the top corner, then choose Delete account. You'll confirm with your password — or, if you sign in with a code, by typing your own name.
What gets deleted depends on who you are:
- A child or a second parent removes only their own account.
- If you're the parent who created the family and there's another parent, they become the owner and only your account is removed.
- If you're the only parent, the whole family and all of its records are deleted with you.
Deletion is immediate and cannot be undone. If you'd rather we did it for you, email support@arc3ventures.com from the address on the account.
