Arrowgami Privacy Policy

Arrowgami is a puzzle game for iPhone and iPad made by by Nu. This policy explains what data is involved when you play, who handles it and what choices you have. In short: your progress stays with you and in your iCloud. In leagues and on the daily challenge's times, others see the name you show and your results. The only ads are videos you start yourself. They come from Google AdMob, and Google only personalises them with your consent.

Last updated: 2026-10-05

Arrowgami has no user account and no servers of its own. Your progress stays on your device and in your own iCloud account, and we have no access to it. Only for leagues and the daily challenge's times does the app create entries with Apple, which you can delete at any time.

1. Who is responsible

The controller for the app under the Swiss Federal Act on Data Protection (FADP) and, where it applies, the EU General Data Protection Regulation (GDPR) is:

  • by Nu
  • Ueberlandstrasse 1, 8600 Dübendorf, Switzerland
  • Email: hello@bynu.ch

2. What stays on your device

Your progress (level, streak, awards, best times and play statistics) is stored locally on your device. The widgets read it on that same device. None of this is sent to us or to anyone else. If you share a solved picture and choose Save Image, iOS asks whether the app may add images to your photos; it can't read them.

From version 1.1, if you turn the evening reminder on, iOS asks whether the app may send notifications. The app schedules the reminders on your device only; nothing is sent for them.

The App Clip (from version 1.1) lets you play a challenge without installing the app. It sends no data to us or to Arrowgami's database. If you solve the daily challenge in it, it keeps the day and your time on your device, and Arrowgami takes them over if you install the app afterwards.

3. Sync through iCloud

If you're signed in to iCloud, the app keeps your progress in step across your devices through iCloud key-value storage. The data lives in your own iCloud account with Apple, and we can't see it. Apple's Privacy Policy applies. You can turn sync off in the app under Settings › iCloud Sync.

4. Leagues and the daily challenge's times

If you're signed in to iCloud and leave leagues on, you play in a group of up to 30 players each week. As soon as you clear your first arrows in a week, the app creates an entry for it in Arrowgami's public database with Apple (CloudKit). It contains:

  • an identifier that Apple issues for Arrowgami only. It doesn't reveal your name, your Apple ID or your email address
  • the name you choose under Settings › How Others See You: your Game Center nickname, a name of your own, or a made-up one such as "Dachshund 42"
  • a country's flag, if you choose one
  • your league, your group, the week and your points that week (the arrows you cleared, weighted by play mode)
  • from version 1.1, the level you've reached. We only look at it in aggregate, to see where players get stuck
  • when the entry was created and last changed

The players in your group see your name and your arrows in the week's table. Technically any copy of Arrowgami can read these entries; only you can change or delete your own. As the provider, we can see the entries in Apple's CloudKit console and delete them, for example in case of abuse. We don't link them to any other data.

The app checks a name of your own for offensive words before saving it. Other players can hide a name on their devices or report it to us. Reporting opens an email to us with the name and the entry's identifier; in case of abuse we delete the entry.

You can turn leagues off in the app under Settings › Leagues, which deletes all your league entries. Without an iCloud account you don't take part in leagues.

The daily challenge's times (from version 1.1)

The first time you solve the daily challenge on its day, the app creates an entry with your time in the same database, as long as you leave Settings › How Others See You › Share My Daily Times on. It holds the same identifier, your name and your flag as above, the day and your time in seconds. Others see the day's fastest times and the times of their league group; you see where your time stands. If you turn sharing off, the app deletes all your times. Without an iCloud account no time is shared.

5. Game Center

If you're signed in to Game Center, the app reports your medals and cups as achievements and your records to leaderboards with Apple. You decide what others see of you in iOS Settings under Game Center. Apple's Privacy Policy applies.

Game Center friends (from version 1.1)

If you turn on Settings › How Others See You › Game Center Friends, iOS first asks whether Arrowgami may read your Game Center friend list. The list stays on your device; the app neither uploads nor stores it. While the switch is on, your league entry and your daily times also hold your Game Center player ID, an identifier Apple gives out only for this developer's games. Friends who have turned the switch on too can then recognise your entries and see you marked in their league and among their daily times. If you turn it off, the app removes the player ID from your entries.

6. Ads from Google AdMob

To keep the game free, it offers videos from Google AdMob that you start yourself: for an extra hint, or to refill your hearts and carry on a level. Arrowgami shows no ads between levels. So that a video starts without waiting, the app loads one in the background; when it does, Google receives the data listed below, even if you never watch a video. This works through the Google Mobile Ads SDK built into the app. For users in Switzerland and the EEA the provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland; for everyone else it is Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.

What Google receives

  • IP address, and from it an approximate location (such as country or city, never a precise location)
  • Device and app information, such as device model, iOS version, language and app version
  • Advertising identifiers: your device's advertising ID (IDFA) only if you allow tracking; otherwise an identifier that is only valid within this app
  • Interactions with ads, such as which video was shown, watched or tapped
  • Diagnostic data about the ads SDK, such as crashes and load times

What Google uses it for

Google uses this data to serve ads, measure how often they are shown, prevent abuse and fraud, and settle payments with us. Personalised ads, meaning ads based on your interests, are only shown with your consent (see section 7). Without consent, Google shows non-personalised ads based only on context, such as the app and your approximate location.

More: How Google uses information from apps that use its services and Google's Privacy Policy. You can manage your ad settings with Google at myadcenter.google.com.

7. Your consent and how to change it

Before the first video starts, the app uses Google's consent form to ask whether Google may use data for personalised ads. After that, iOS asks whether the app may track you across other companies' apps and websites (App Tracking Transparency). Until you've answered, all ads are non-personalised. Both are optional, and the game works fully either way.

  • You can change or withdraw your ad consent at any time in the app under Settings › Ad Privacy Choices.
  • You can turn tracking off in iOS Settings under Privacy & Security › Tracking. Google then doesn't receive your device's advertising ID.
  • Your choice is stored only on your device.

8. Purchases through Apple

Purchases in the app, the streak freezer and, from version 1.1, the board themes and tips, are handled by Apple through the App Store. We never receive payment details, only confirmation that a purchase was made. Whether you own the board themes, the app reads from the purchase records on your device.

9. Crash reports from Apple

If you've agreed in iOS Settings to share analytics with app developers, Apple gives us anonymised crash reports and usage statistics. They don't identify you, and we only use them to fix bugs.

10. If you email us

If you email us, we use your address and message to answer you and delete them once they are no longer needed.

11. Legal bases

Leagues, the daily times and the Game Center connection are part of the game you use (Art. 6(1)(b) GDPR), and you can turn each of them off at any time. Personalised ads, and storing information on your device for them, are based on your consent (Art. 6(1)(a) GDPR). Non-personalised ads, fraud prevention and billing are based on our legitimate interest in funding the game through ads (Art. 6(1)(f) GDPR). Handling purchases is necessary to perform the contract (Art. 6(1)(b) GDPR). In Switzerland we process data in line with the principles of the FADP.

12. Transfers abroad

Google and Apple also process data outside Switzerland and the EEA, particularly in the USA; this includes league entries and daily times in CloudKit. Google LLC and Apple Inc. are certified under the EU-U.S. Data Privacy Framework and the Swiss-U.S. Data Privacy Framework. The providers also rely on the European Commission's Standard Contractual Clauses.

13. How long data is kept

Data on your device stays until you delete the app. Data in iCloud stays until you delete it from your iCloud account. League entries stay until you turn leagues off or ask us to delete them, daily times until you turn sharing off or ask us to. How long Google keeps advertising data is set out in Google's Privacy Policy.

14. Children

Arrowgami is suitable for all ages and made for a general audience, not specifically for children. Apart from league entries and daily times, which can be deleted at any time, we don't collect any data ourselves, including from children. Children under 16 should only agree to personalised ads with a parent's permission. Parents can change the consent and turn leagues and shared daily times off in the app at any time, and block tracking in iOS Settings or through Screen Time.

15. Your rights

You have the right to access, rectify and erase your data, to restrict or object to its processing, to data portability, and to withdraw consent at any time. You can delete your league entries and daily times yourself by turning leagues or shared daily times off. As they only carry an identifier and a name of your choosing, we can't match them to you without further details. Requests about advertising data are mainly for Google. We're glad to help: hello@bynu.ch. You can also complain to the Swiss Federal Data Protection and Information Commissioner (edoeb.admin.ch) or to the data protection authority in your EU country of residence.

16. Changes

If the app changes in a way that involves different data, we'll update this policy. The version published here applies, and the date at the top shows the last change.
