Privacy policy for Dartcaster
Last updated: 12 November 2026
In short
- You do not need an account. We have no server of our own and we do not receive your game data.
- Camera images are processed on your phone and never leave it.
- Players, scores and statistics are stored only on your phone.
- If you choose a free evening with short videos, Google AdMob shows those videos. Google processes data about your device when it does. Where the law requires it, we ask for your consent first. Your answer does not affect the free evening.
- A purchase is handled entirely by Apple.
1. Who is responsible
Tim Geerlings makes the app Dartcaster and is responsible for the processing of personal data described in this policy (the controller under the GDPR).

2. What stays on your phone
Camera. With camera scoring, your iPhone films the dartboard. The app looks for the board and the darts in those images, on the phone itself. The images are not stored as photos or video and are not sent anywhere, including to us. The app does store the set-up of your board on your phone, with a small greyscale image of the board only. That lets it recognise your board next time and notice when the camera has moved. The app only asks for camera access when you choose camera scoring. You can withdraw access at any time in the iOS settings.
Players, scores and statistics. The names you enter, the scores, the throws and the statistics (such as averages and checkouts) are kept in a database inside the app, on your phone. Your settings, whether you have unlocked camera and TV and your ad consent choice are also stored on your phone. We do not receive this data. If you back up your iPhone to iCloud, it is included in that backup; Apple handles that.
Microphone and speech recognition. The app does not use the microphone or speech recognition and does not ask for access to them. If voice control arrives later, we will update this policy first.
Location. The app does not ask for your location.
3. The scoreboard on your TV (Chromecast)
When you tap the cast icon, the app looks for a Chromecast or a TV with Chromecast built-in on your Wi-Fi. iOS first asks for permission to use the local network. The scoreboard goes from your phone to the TV over your own network, with the players' names and the score.
- The TV page. The Chromecast loads the scoreboard page from our web host Cloudflare. As with any website visit, the web host sees the IP address of your network; player names and scores are not sent to the web host. Cloudflare processes these log files on our behalf and keeps them under Cloudflare's data processing terms.
- This website. dartcaster.nl is also hosted by Cloudflare, which sees your IP address when you visit. The website itself sets no cookies, does not measure visitors and loads nothing from other parties.
- Google. The TV page loads Google's Cast software and a font from Google Fonts. Google sees the IP address of your network when it does.
- The Cast software in the app. The Google Cast software in the app sends Google technical data about casting: a device ID, data about faults and how the cast button is used. Google uses it to make Cast work and to improve it. According to the software's own privacy declaration (its privacy manifest), Google does not link this data to you and does not use it to track you.
- Your Chromecast or TV is otherwise covered by its maker's terms.
4. Short videos for a free evening (Google AdMob)
Camera scoring and the TV scoreboard are free for an evening (until 6 am) if you watch about a minute of short videos. These videos are Google AdMob ads. They appear only on your phone, never on the TV, and only when you tap "Watch the videos" yourself. Only then does the app start Google's ad software.
Two questions first.
- If you are in the European Economic Area, the United Kingdom or Switzerland, the app first shows Google's consent form (based on the IAB TCF standard). There you choose whether Google and its partners may store and read data on your phone and whether ads may be tailored to you.
- Then iOS asks whether the app may track you across apps and websites owned by other companies (App Tracking Transparency). If you allow it, Google receives your iPhone's advertising identifier. If you do not, Google does not receive it.
Your answers only decide which ads you see. You get the free evening in every case, even if no video loads. If you close a video before it ends, you can try again.
What Google collects. According to Google, its ad software (the Google Mobile Ads SDK) may collect:
- a device ID, such as your iPhone's advertising identifier (only if you allow tracking) or an identifier that only applies within this app or this developer's apps;
- advertising data, such as which ads you have seen;
- an approximate location, derived from your IP address;
- how you use the app and the ads, such as taps and video views;
- performance and crash data, such as launch time and crash logs.
Google uses this data to show and measure ads, to prevent fraud, to improve its services and, only if you consent, to tailor ads to you. Without that consent, Google shows ads without a profile, based on the app and your approximate location, and uses identifiers only for things like counting views, as far as the law allows.
For these ads, Google is an independent controller. How Google handles your data is described in Google's privacy policy and on the page "How Google uses information from sites or apps that use our services" (links below). You can manage your ad settings with Google at myadcenter.google.com.
5. The purchase
If you unlock camera and TV for good, you buy that through the App Store. Apple processes the payment. We do not receive your name, email address or payment details. The app only asks Apple whether this Apple ID already owns the purchase, for example when you tap "Restore purchase". How Apple handles your data is described in Apple's privacy policy.
6. If you email us
If you email support@dartcaster.nl, we use your email address and what you write to answer your question. We keep the email until your question has been dealt with and for at most 12 months after that, in case you come back to it.
7. Legal bases
| What | Legal basis (GDPR, Article 6(1)) |
|---|---|
| Ads tailored to you | Consent (a). For storing and reading data on your phone, also consent under Article 11.7a of the Dutch Telecommunications Act (the national rule based on the ePrivacy Directive). |
| Ads without a profile | Our legitimate interest in offering the free evening (f). Where the law requires consent for the use of identifiers, we ask for it through Google's form. |
| Keeping your consent choice | Legal obligation to be able to show that you consented (c, with Article 7(1) GDPR). |
| The purchase and "Restore purchase" | Performance of the contract (b). |
| Cast data and the log files of the TV page | Our legitimate interest in making the scoreboard work on your TV (f). |
| The log files of the website | Our legitimate interest in keeping the website online and secure (f). |
| Your email to us | Our legitimate interest in answering your question (f). |
We do not process the data that stays on your phone (section 2): we never receive it.
8. How long
- On your phone: until you delete the app. All of the app's data is then removed from your phone. An iCloud backup follows Apple's rules.
- The free evening: ends at 6 am.
- Your consent choice: on your phone, until you change it or delete the app.
- At Google: according to Google's retention policy. In its advertising log files, Google removes part of the IP address after 9 months and cookie information after 18 months.
- At Apple: according to Apple's privacy policy.
- Log files of the TV page and the website: under Cloudflare's data processing terms.
- Your email to us: until your question has been dealt with, then at most 12 months.
9. Sharing and transfers outside Europe
We share data only with the parties in this policy: Google (ads, Cast, Google Fonts), Apple (the purchase) and our web host Cloudflare (the TV page and the website). We do not sell data. These parties must protect your data at least as well as this policy describes. Google does so under the Google Ads Controller-Controller Data Protection Terms (which cover AdMob) and its privacy policy, Apple under its privacy policy.
Google and Apple may process data outside the European Economic Area, including in the United States. Google states that it complies with the EU-U.S. Data Privacy Framework and, where required, uses the European Commission's Standard Contractual Clauses. Apple describes how it does this in its privacy policy.
10. Your rights
You have the right to access, correct, delete, restrict and transfer your data and to object, and you can withdraw consent at any time.
- Data on your phone is under your control. If you delete the app, it is gone.
- Changing your ad consent: in the app under Settings > Privacy > Ad consent. Turn tracking on or off in the iOS settings: Settings > Privacy & Security > Tracking.
- Data held by Google: Google has its own tools to see and delete your data; see Google's privacy policy.
- Data held by us: we only have your email, if you emailed us. Ask via support@dartcaster.nl; we reply within one month.
If you disagree with how we handle your data, you can complain to the Dutch Data Protection Authority, the Autoriteit Persoonsgegevens (autoriteitpersoonsgegevens.nl), or to the supervisory authority in your own country.
11. Children
Dartcaster is not aimed at children under 13. We do not ask anyone's age. In the EU, the age from which you can consent yourself to ads tailored to you is between 13 and 16, depending on your country (16 in the Netherlands; Article 8 GDPR). If you are younger, choose not to consent in the form, or ask a parent. You get the free evening either way. If we find out that a child under 13 has emailed us, we delete that email.
12. Security
Your game data is stored on your phone and protected by iOS security, such as your passcode. Connections to Google and Apple are encrypted.
13. Changes
If the app changes, for example when voice control is added, we will update this policy. The date at the top shows when it last changed. For a significant change we will also say so in the app or in the App Store update notes.
