Starday Privacy Policy

Last updated: 5 September 2026

Starday is a routine and reward app for families, made by gosu.team ("we", "our", "us"). This policy explains exactly what the app stores, why, and how to get rid of it. It covers the Starday iPhone app, the Starday Android app and the Starday web app.

1. The short version

There are no accounts. We never ask for an email address, a phone number, a password or a date of birth.
There is no advertising, no analytics and no tracking of any kind in Starday. We do not profile anyone and we never sell or rent data.
We store the things you type into the app — your child's display name, their tasks, rewards, points and mood entries — so the family can share one board across devices.
You can delete it yourself at any time from inside the app, or ask us to.

2. What we store

A family in Starday is identified by a 6-character family code, not by a person. Under that code we store:

The child's display name and avatar, as typed in by whoever set up the profile. A first name or a nickname is all the app needs.
Tasks and routines — titles, icons, schedules, deadlines and whether each one is done.
Rewards you add to the shop, rewards your child has claimed, and their points balance.
Mood entries — the emoji a child taps for a given day, if they use that feature.
A parental passcode, stored only as a non-reversible hash. We cannot read or recover the passcode itself.
An anonymous device identifier created by Firebase so the app can talk to the database. It is not linked to you, your device's advertising ID, or any account.
The date the family was created, which is used to work out how many free days of the rewards shop are left.

If you buy a subscription, our payments provider also records that a purchase happened and its renewal status, linked to the family code.

3. What we do not collect

To be unambiguous, Starday does not collect or receive:

email addresses, phone numbers or postal addresses
your child's age or date of birth
location of any kind, precise or approximate
contacts, photos, files, calendar entries or messages
advertising identifiers, or any data used for advertising
analytics, usage statistics, behavioural profiling or crash telemetry

There is no advertising SDK, no analytics SDK and no third-party tracker in any version of the app.

4. Children's privacy

Starday is built to be used by children, with a parent or guardian setting it up and controlling it behind a passcode.

We do not knowingly collect personal contact information from a child. The app has nowhere for a child to enter an email address, a phone number or a real-world address.
The only thing a child's profile needs is a display name. We recommend using a first name or a nickname rather than a full name.
Everything a child enters — tasks, rewards, moods — stays within the family and is visible only to devices that have the family code.
A parent or guardian can view, change or delete all of it at any time from the Parental Zone.
We never show children advertising, and we never show prices or a purchase screen to a child. Subscriptions live behind the parental passcode.

If you believe a child has given us information we should not hold, email [email protected] and we will delete it.

5. How we use it

We use the data above for one purpose only: to make the app work — to show your family's board, keep devices in sync, award and deduct points, and unlock Pro features for subscribers.

We do not use it to advertise, to profile you, to train models, or to build any picture of you beyond the app itself.

6. Who else handles it

We use a small number of service providers who process data on our behalf and are not permitted to use it for their own purposes:

Google Firebase — anonymous sign-in and the database that stores your family's board.
RevenueCat — keeps track of whether a family has an active subscription.
Apple, Google and Stripe — process payments when you subscribe, each under their own privacy policy. We never see your card details.

That is the complete list. We do not sell, rent or share your data with anyone else, and we do not share it for advertising.

7. Where it is stored

Family data is stored in Google Firebase in the European Union (europe-west1). All traffic between the app and our services is encrypted in transit with HTTPS/TLS.

8. About the family code

Please read this one. The family code is what links devices to a family, and it works like a shared key: anyone who has your family code can see and change that family's board.

Treat it like a password. Share it only with people you want to have access — your own household — and do not post it publicly. If a code is shared more widely than you intended, the safest fix is to delete the profiles and set up a fresh family, which gives you a new code.

The 4-digit parental passcode is a gate on the app's interface to keep children out of the parent area. It is not a security boundary against an adult who already has the family code.

9. Keeping and deleting data

We keep a family's data for as long as the family exists. There is no inactivity expiry, so nothing is deleted behind your back.

You can delete it whenever you like:

In the app — Parents → Family → delete a child's profile. This permanently removes that child's name, avatar, tasks, rewards, points and moods.
By email — write to [email protected] with your family code and we will delete the whole family for you.

Full instructions are on our Delete your Starday data page.

Deleted data may remain in encrypted backups for up to 30 days before those roll over. Records of purchases are kept by our payment providers for as long as tax and accounting law requires.

10. Your rights

Depending on where you live, you may have the right to access, correct, export or delete the data we hold, to object to or restrict how we use it, and to complain to your local data protection authority.

Because Starday has no accounts, the quickest route for all of these is to email [email protected] with your family code. We answer within 30 days.

11. Changes to this policy

If we change what we collect or how we use it, we will update this page and change the date at the top. Significant changes will be announced in the app.
