Children's privacy

Last updated: 10 November 2026 · version 2026-11-10

Draft: this text is awaiting legal review. This note will be removed when the final version is published.

This page is written especially for parents and guardians. Wunderstrike is a football game for players of all ages, and it was designed with children's safety in mind from the start. Below we explain what information about your child we process, why, and what you can control.

1. In short

  • No free chat; only 12 short preset messages.
  • No matching with strangers; online matches only with mutually approved friends.
  • No advertising ID, ad SDKs, analytics SDKs, location, contacts or microphone.
  • Children under 13 cannot use online and social features without parental consent.
  • We do not ask for real names. There are currently no real-money purchases in the game.

2. How we ask for age

In the game: before friends features or the photo feature are used for the first time, we ask once for the birth year only. We do not ask for the full date of birth. We store: birth year, the declaration (under 13 / 13 or over) and the time of the declaration. The single-player part of the game can be played without being asked for age.

For the beta sign-up (website): the form asks for an age bracket (18+ / 13–17 / under 13).

3. Under 13: parental consent

In the game

  • When a child wants to turn on friends features, the game shows a 6-digit code valid for 10 minutes.
  • A parent opens Wunderstrike on their own device and enters the code using a profile declared as 18 or over.
  • The parent is then linked to the child's account and automatically becomes their friend.
  • We store: the parent's game user ID, the consent time and (if withdrawn) the withdrawal time.
  • The parent can withdraw consent at any time; online/social features are then turned off.

For the beta sign-up

  • For an under-13 sign-up we ask for a parent's e-mail address and a parental consent box.
  • The verification link is sent to the parent's e-mail, not the child's. The child is added to the beta only if the parent approves via that link.
  • If the parent does not approve, the unverified sign-up is deleted after 30 days.

4. Ages 13–17

In the game, players aged 13 and over can use friends features without a parent code. For the beta sign-up, we ask 13–17-year-olds to confirm that a parent knows about the sign-up. We recommend that parents read this page together with their child.

5. What under-13s cannot do without parental consent

  • create or enter friend codes,
  • send or receive preset messages,
  • send or accept match invites,
  • use the photo-to-player feature.

Single-player matches and the offline parts of the game can be played without consent.

6. Friends and communication

  • Adding a friend requires a 6-digit friend code (or a QR code containing it) that is valid for 24 hours and single-use. Codes are typically shared between people who know each other or sit side by side.
  • Friendships need mutual approval; up to 100 friends. Friends can be removed and blocked.
  • There is no player search, no public lobby and no random matchmaking.
  • There is no free typing; only 12 preset messages (e.g. "Good game!") can be sent.
  • Friends see the display name, which is at most 16 characters and passes a word filter. We recommend not using a real name.

7. Ads and sponsor billboards

The game has no ad SDK and no advertising ID; your child is not shown personalised or behavioural ads. The billboards in the stadium may only show sponsor campaigns selected as suitable for children. Selection is based on a coarse region, not on the individual. For children under 13, region information is not stored; it is only used for that request. Impressions are counted in aggregate per day, billboard slot, campaign and coarse region, without any user ID.

8. Purchases

The game has stars, earned by playing. Diamonds, to be bought with real money, are planned but not available yet, and there is no purchase code in the game. If purchases are added in future, they will be cosmetic only, give no gameplay advantage, and we plan to put a parental gate (adult check) in front of them. We will update this page when this changes.

9. Photo-to-player feature

  • Requires the age entry; under 13 requires parental consent.
  • Only the face area of the chosen photo (max 128×128 pixels) is cropped and sent to our server.
  • The server keeps the photo in memory only, scales it to 64×64 and sends it to the PixelLab service to create a pixel portrait. The photo is not written to disk or logs and is discarded as soon as the job is done.
  • Only the generated 64×64 pixel portrait is kept. Up to 3 portraits per day.
  • The photo is not used for face recognition or identification.
  • Without internet, only a simple placeholder is drawn on the device.
  • PixelLab's own retention and location: [doğrulanacak: PixelLab saklama süresi / konumu; şartlarına göre görseller kullanıcıya aittir ve model eğitiminde kullanılmaz].

Please remind your child to use only their own photo, or photos they have permission to use.

10. What you can do as a parent

  • See: as a linked parent you appear as your child's friend and see their display name and profile. To request a copy of the data we hold about your child, write to destek@wunderstrike.com.
  • Withdraw consent: in the game, through the parent link, at any time.
  • Delete the account: on your child's device, PROFILE → delete account (two steps), or write to destek@wunderstrike.com.
  • Delete the beta sign-up: write to hello@wunderstrike.com.

We may ask some verification questions to make sure the request really comes from the parent. Deleted data also disappears from backups within 30 days at the latest.

11. Principles we follow

For children's privacy, we use the common principles of rules such as the US COPPA and the child-related provisions of the EU GDPR as a guide: minimal data, parental consent, no behavioural advertising, no contact with strangers, and easy deletion. We do not claim any certification or membership of an official approval programme. Which laws apply in which country: [hukukçu doğrulayacak].
