Privacy Policy
Short version: no account, no login, no server. Everything the app remembers stays on your own device. The ads are Google's, and most of this page is about that.

The short version
Element of the Day has no account, no login and no server. Everything the app remembers about you — the theme you picked, how you did on the quizzes — is stored on your own device and is never sent anywhere.
The app is free because it shows ads, and those ads are served by Google. Google collects some information in order to do that. That is the only third party involved, and this policy is mostly about what it does and how to limit it.
1. Who this is from
Element of the Day is an iOS app published by HYL Technology Solutions ("we", "us"), based in Canberra, Australia. If you have a question about anything below, write to ryanhyl.working@gmail.com and we will answer.
2. What stays on your device
The app stores the following in a private container on your device, shared only between the app and its home screen widget. None of it is transmitted to us or to anyone else, and we have no way of reading it:
- Which of the six themes you have chosen, and — if you are using a themed trial — when that trial ends.
- Your daily quiz history: which answers you gave and whether they were right.
- Which ad style you have chosen in About ▸ Ads.
- Small bookkeeping flags, such as whether the app has been opened before and which day it last showed an ad.
There is no analytics service in the app, no crash reporting service, and no advertising or tracking library other than Google's, described below. We do not collect your name, email address, location, contacts, photos, or anything you type.
Deleting the app deletes all of it. There is nothing left behind for us to remove, and nothing for you to request.
3. Advertising
Ads in Element of the Day are served by Google AdMob. To serve and measure them, Google may collect and process:
| What | Why |
|---|---|
| Your device's advertising identifier (IDFA) | To choose ads and to measure whether they worked. Only if you allow tracking — see below. |
| IP address | To work out roughly where you are, so ads are in the right country and language, and to prevent fraud. |
| Device and app information | Device model, operating system version, language, and the fact that the ad came from this app. |
| Ad interactions | Which ads were shown, how long for, and whether they were tapped. |
Google acts as an independent controller of this data, not as our processor. What it collects and how long it keeps it is governed by Google's own terms:
- Google Privacy Policy
- How Google uses information from sites or apps that use its services
- Ad technology providers Google may share data with
We ourselves receive only anonymous, aggregated totals from Google — how many ads were shown across all users and what they earned. Nothing in those reports identifies anyone.
Your choices about ads
- App Tracking Transparency. The first time you open the app, iOS asks whether Element of the Day may track you across other companies' apps and websites. Saying no is fine — the app works exactly the same and you still see ads, they are just chosen from context rather than from your interests. You can change your answer at any time in Settings ▸ Privacy & Security ▸ Tracking.
- Consent (UK, EU and EEA). If you are in the UK, the EU or the wider EEA, a Google consent form appears before any ad is requested, letting you accept or refuse personalised advertising and see which partners are involved. Your answer is remembered, and you can change it later from the same form.
- Reset or limit the advertising identifier in Settings ▸ Privacy & Security ▸ Apple Advertising.
- Remove ads entirely by subscribing to Element of the Day Plus. With Plus active, no ad is requested and no ad SDK data is sent at all.
4. Purchases
Element of the Day Plus is an auto-renewing subscription sold through Apple's App Store. Apple handles the payment; we never see your card details, billing address or Apple Account. The app asks Apple only one question — whether this device currently holds an active subscription — and stores the answer nowhere.
Apple's handling of that transaction is covered by the Apple Privacy Policy. You can manage or cancel a subscription in Settings ▸ Apple Account ▸ Subscriptions.
5. Who this app is for
Element of the Day is not directed to children under 13 and we do not knowingly collect any information from them. It is written for secondary-school and university students and for anyone else with an interest in the periodic table.
Because a meaningful share of that audience is under 18, we cap the maximum ad content rating for this app at Google's “Teens” level — set both in our AdMob account and in the app's own ad requests, so the limit holds either way. Ads rated for mature audiences, including alcohol, weapons and sexual content, are never served here. Where a user is identified as being below the age of digital consent in their country, Google serves non-personalised ads only.
If you believe a child under 13 has used the app and you would like to raise a concern, please write to us at the address above.
6. Legal bases, if you are in the UK or EU
- Consent — for personalised advertising and for use of the advertising identifier. This is what the consent form and the tracking prompt are for, and you may withdraw it at any time by the routes listed above.
- Legitimate interests — for serving non-personalised ads, measuring them in aggregate, and preventing ad fraud, which is what keeps the app free.
- Performance of a contract — for processing a subscription you have chosen to buy.
7. Your rights
Depending on where you live, you may have the right to access, correct, delete, or export personal data held about you, to object to processing, and to complain to a regulator.
Because we hold no personal data about you at all, there is nothing for us to produce, correct or delete — deleting the app removes everything the app itself stored. Requests relating to data Google holds should go to Google, using the links above; we can point you in the right direction but we cannot act on its systems.
In the UK you may complain to the Information Commissioner's Office; in the EU, to your national data protection authority. In Australia, to the Office of the Australian Information Commissioner.
8. If you are in California
We do not sell your personal information for money. However, allowing personalised ads may count as "sharing" personal information for cross-context behavioural advertising under California law. Declining the App Tracking Transparency prompt, or subscribing to Plus, opts you out of that entirely.
9. Data retention
We retain nothing, because we receive nothing. Data held by Google is retained according to Google's own retention schedules, set out in its privacy policy.
10. Changes to this policy
If this policy changes in a way that matters, the date at the top changes with it and the new version replaces this page. Continuing to use the app after that means the new version applies.
