Privacy
KidDay is used by parents to plan a morning with a small child. That means the data is about a family, so there is less of it than you might expect, and this page says exactly what there is, why we hold it, and how long for.
Who runs KidDay
KidDay is made and run by one person, not a company. There is no business behind it, no investors, no staff, and no revenue of any kind — it is free because it costs almost nothing to run, not because you are the product.
That is worth saying plainly, because "we will never sell your data" is a promise every app makes and few can back. Here there is nothing to sell it for: there is no advertising in the product, no ad network is ever contacted, no affiliate links, and no paid tier. If that ever changes, this page changes first and you will be asked to agree again.
Because it is a personal project rather than a registered business, there is no company address to print here. The way to reach a human is privacy@kiddayout.com, and it is read by the person who built it. If a regulator or a legal process requires identifying details, they will be given.
The short version
- Signed out, we hold nothing that identifies you. The app works signed out.
- We never sell your data, never share it for advertising, and run no third-party analytics.
- We hold a nickname and a birth year for a child — never a full name, never a date of birth, never a photograph.
- You can delete your history or your entire account yourself, in two taps, immediately.
What we hold, and why
Each row says what it is for. If a purpose ends, so does the reason to hold the data.
| What | Why we hold it |
|---|---|
| Your email address | To send the sign-in link. It is the only direct identifier in the system. |
| A nickname and birth year for each child | To judge whether a session suits your child's age. A year is enough; a date of birth is not needed and is not asked for. |
| Your home area, rounded to about 1.1 km | To judge whether something is close enough to get to. We round on arrival and keep only the rounded value. |
| Your settings | Notification time, how far you will drive, whether you prefer free things, categories you have muted. |
| What you were shown, and what you marked | So the plan stops offering the same storytime every morning. |
| Notes you write | To help other parents judge a place. Every note is public to other parents — there is no private note, and the box says so before you type. A note appears with your first name and your child's age, like "— Sam, parent of a 4yo", for up to a year. |
| A push subscription | Only if you turn the morning notification on. |
| A random id your browser makes for itself | Hashed with the date before storage, so we can count how many devices opened the app on a day. Not a fingerprint: nothing about your device goes into it, and clearing site data resets it. |
| That you agreed to these terms, and which version | Because an agreement nobody can evidence is not an agreement. |
Children
This is the section that matters most, so it is not buried.
- The account belongs to the parent or guardian. The service is designed for, and directed to, adults planning an outing.
- We do not knowingly collect anything from a child. Everything we hold about a child was typed by their parent.
- What we hold about a child is a nickname you choose and a birth year. No full name, no date of birth, no photograph, no location of the child, no contact details.
- A child's information is never used for advertising, never sold, and never shared for anyone else's purposes.
- Deleting your account removes your children's details immediately and permanently. You do not have to ask us.
- If you believe a child has given us information directly, write to privacy@kiddayout.com and we will delete it.
What we do not do
- No advertising, no ad networks, no marketing profiles, no data sold or shared for money.
- No third-party analytics, no social pixels, no session recording.
- No third-party code at all. The app has no runtime dependencies, and the two typefaces are served from this site rather than from a font CDN, so opening a page does not disclose your address to anyone else.
Who else is involved
These are the only outside services. If we add one, this list changes before it starts.
| Who | What they see | Where |
|---|---|---|
| Cloudflare | Hosting and the database — everything above. | United States |
| Resend | Your email address, to deliver the sign-in link. | United States |
| Anthropic | Public event listing text, and anything you type into the ask box. Not your email address, not your children. | United States |
| Open-Meteo | The city's forecast. No personal data. | — |
| OpenStreetMap | Map tiles are fetched by your browser, so OpenStreetMap can see your IP address when you open the map. Every other page avoids this. | — |
| Google Maps | Only if you tap for directions, which opens Google in a new tab. Nothing is sent until you tap. | — |
Your data is stored in the United States. If you are reading this from elsewhere, that is where it goes.
Machines that decide things
Which three things you are shown is chosen by a ranking program, not a person, using your child's age, the weather, distance and what you have already been shown. The sentence at the top of your morning is written by a language model from those picks. Neither decision has a legal or similarly significant effect — the worst outcome is a dull suggestion — and you can change the age, the settings, or ignore it entirely.
Text you type into the ask box is sent to Anthropic to be interpreted. It is not used to train anyone's model.
Cookies
Two, both first-party, neither for tracking. A session cookie that keeps you signed in, and a small flag recording that you have opened the app before so you are not shown the introduction again. No advertising or analytics cookies are set, so there is no consent banner to click.
How long we keep it
A nightly job enforces every line of this, and it can be run on demand.
- A sign-in link: 15 minutes, and it works once.
- Being signed in: 30 days, then you sign in again.
- A plan you shared by link: 7 days, then the link stops working and the copy is deleted.
- Answers to questions asked in the ask box: 2 days.
- Counters that stop one person overloading the service: 2 days.
- A note you deleted: removed entirely after 30 days.
- What was shown to you and what you marked: 400 days. Its influence on your plan fades over about 60 days regardless.
- The hashed device counts: 35 days.
- Your account and your children's details: until you delete them.
Your rights, and how to actually use them
Two of these are buttons in the app, under You. Neither needs to go through us, and neither waits on us.
- Delete my history removes everything you have saved, done, been shown, and written.
- Delete my account removes all of that plus your email address, your children's nicknames and birth years, your home area, your settings, your push subscription and any plans you have shared. It is immediate and it cannot be undone.
For anything else — a copy of what we hold, a correction, or a question about any of it — write to privacy@kiddayout.com. We will answer within 45 days, and tell you sooner if the answer needs longer. If you are unhappy with how we handled it, reply and say so: a different person will look at it again, and we will tell you the outcome. Depending on where you live you may also complain to your data protection authority or attorney general, and nothing here takes that away.
We will not charge you, and we will not treat you differently, for using any of this.
If something goes wrong
If we discover a breach that puts your information at risk, we will tell affected parents without undue delay and in any case within the time our law requires, say what happened and what we are doing, and notify the regulators we are required to notify. We will not wait for certainty about the cause before telling you there is a problem.
Changes
The date at the top changes when this page changes. If a change materially affects what you agreed to, we will ask you to agree again rather than assume.
Getting in touch
Write to privacy@kiddayout.com for anything on this page, including a copy of what we hold about you. A person reads it.
