That's a Day? is a small app for discovering the fun, quirky holidays happening today. It works without an account, and most of it works without sending us anything at all. This page describes exactly what the app does collect, what it doesn't, and how to have anything removed.
It covers both the iPhone and iPad app and the Android app. The two are built separately and the platforms differ in real ways, so wherever the behaviour is not the same, this page says which is which rather than describing one and hoping the other is close enough.
| What | When | Where it goes |
|---|---|---|
| Email address | Only if you enter it in "Stay in the loop" | Our database (Google Firebase). Stored with the date you submitted it and a note that it came from the app — nothing else. |
| Usage events | Automatically, while using the app | Google Firebase Analytics |
| Advertising data | When an ad is shown (free version only) | Google AdMob. On iPhone and iPad your advertising identifier is included only if you allow tracking when the app asks. On Android there is no such prompt, so it is included unless you have turned it off in Android's settings. |
| Approximate location | Only when you tap "Use my location" | Never sent to us. Rounded first, then sent to the service that runs the search: Apple Maps on iPhone and iPad, a public OpenStreetMap query service on Android. |
| Purchases | If you subscribe to Pro | Handled entirely by Apple on iPhone and iPad, and by Google Play on Android. We never see your payment details. |
The app offers to email you occasional updates. That prompt is optional and dismissable, and the app is fully usable if you never enter an address. If you do, we store the address, the date, and the fact that it came from the app. It is not linked to your usage of the app, because the app never sends us an identifier that would allow that. To have it deleted, email us — see Contact.
The app records how it is used, so we can tell which parts are worth improving. That includes which screens are opened, which holidays are tapped, how far you get through onboarding, whether you allowed notifications, and whether a purchase succeeded. These events are not linked to your email address, and the app does not set a user ID.
The free version shows ads through Google AdMob. Pro subscribers see no ads at all.
The advertising identifier works differently on the two platforms, because the platforms are built differently. It is worth reading the part that applies to you.
Once you have used the app a few times, iOS will ask whether That's a Day? may track you across other companies' apps and websites. It is asked once, and not on your first visit. That prompt controls access to your device's advertising identifier (IDFA):
You can change your mind at any time in iOS Settings › Privacy & Security › Tracking.
There is no equivalent prompt, and we do not show one. Android has no App Tracking Transparency; the advertising ID is a device-level setting rather than a per-app permission, so a prompt from us would not actually control anything. In practice that means the identifier is available to ads in the app unless you have turned it off yourself:
On both platforms you will see a Google consent form, covering how Google may use data to personalise ads. On iPhone and iPad it appears before the tracking prompt described above. Your answer is recorded by Google.
To change that answer: on iPhone and iPad, use Settings › ad privacy choices inside the app — that row appears only where such a choice applies. The Android app does not yet carry that row; until it does, you can reset the choice by clearing the app's storage (Android Settings › Apps › That's a Day? › Storage), or by writing to us at the address in Contact and we will tell you where it has got to.
Either way, Google processes data to serve and measure ads under its own policy — see how Google uses information from sites or apps that use its services.
Some holidays show a "Where to celebrate" section with places near you. This is the only feature that uses location, and it is entirely opt-in.
The search itself has to run somewhere, and that differs by platform:
If you would rather not share a location at all, both apps let you type a postcode or ZIP code instead. We do not store it. It is turned into coordinates by the platform's own geocoder — Apple's on iPhone and iPad, Android's built-in one on Android — and then used exactly as above.
You can withdraw location access at any time: on iPhone and iPad in Settings › Privacy & Security › Location Services, and on Android in Settings › Apps › That's a Day? › Permissions › Location. The rest of the app works normally without it.
If you allow notifications, daily and weekly reminders are scheduled on your device — by iOS on iPhone and iPad, and by Android's own scheduler on Android. Their content never leaves your phone, and we do not operate a push server on either platform.
We use a small number of third parties, and each has its own policy:
Depending on where you live, you may have rights to access, correct, or delete personal information we hold, or to object to its processing. Because the only personal information we hold is an email address you chose to give us, those requests are usually a one-line email away. Write to us at the address below and we will action it.
That's a Day? is a general-audience app. It is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has submitted an email address to us, contact us and we will delete it.
Email addresses are kept until you ask us to remove them. Analytics events are retained according to Google Firebase's default retention period for the project. We retain nothing about your location, because we never receive it — the map services described above handle those requests under their own policies.
Questions, deletion requests, or anything else about this policy:
If this policy changes in a way that affects what is collected, we will update the date at the top of this page. The app's behaviour and this page are meant to describe each other exactly; if you ever find them disagreeing, the discrepancy is a bug — please tell us.
