Registration and management of children’s accounts

We process display names and email addresses, together with participation type and age group. For new accounts, WordPress stores a password verification value. Existing accounts retain their password and permissions. Email confirmation is required before the matching service can be used.

Adults confirm that they are at least 18. For children, an adult authorised legal representative manages the account using their own email address. We store that adult’s name, the child’s first name or nickname, the age group and the declaration of authority to represent the child, including any required consent from other persons with parental responsibility. One account represents one player in both sports. We collect neither identity documents nor an exact date of birth. Age and authority to represent the child rely on self-declarations; email confirmation is not an identity or parenthood check.

For participation, we store the request time, final email confirmation time, declaration version, confirmed details and the participation information linked at that time. Changes to participation details take effect only after a new email confirmation. They close affected active game proposals.

Sport profiles and matching

We store the sport, self-assessed playing level, optional tennis performance rating (LK) and selected venues. General days of the week and times of day are optional preferences. Neither a specific date nor a time is required to search for partners. Matching takes account of similar playing levels, the same age group and shared venues. Time preferences affect only the order of suitable groups and do not exclude other suitable players. Games already accepted are taken into account when specific dates are proposed. The groups are under 10, ages 10–13, ages 14–17 and adults aged 18 or over. There is no public profile directory.

During a search, confirmed, signed-in participants can already see compatible players‘ display names and playing levels, shared venues and indications of shared voluntary time preferences. There is no public profile overview. A specific date is stored only when a game proposal is sent.

For a game proposal, we store the accounts involved, who sent that proposal, sport, age group, venue, date, start and end time, confirmations, cancellations, status and any reported reservation. Participating accounts receive fellow players‘ display names and levels, together with shared game and status information. Account IDs are also transmitted technically. The extension does not display a parent’s name, full profile or email address to fellow players. David and authorised people with administration permissions can view the private participation and date overview containing account, profile, proposal and status details. They may cancel active proposals but cannot replace a participant’s consent.

Proposals are calculated automatically. The system makes no decision with legal or similarly significant effects: everyone decides for themselves whether to participate. For children, the adult managing the account confirms the date.

Legal bases

We process the account, profile, matching and game-date details, and necessary notifications required for the requested free participation agreement, to prepare and perform that agreement under Article 6(1)(b) GDPR. For minors, their legal representative participates on their behalf. Reading this privacy information and accepting the participation terms does not constitute blanket consent to data processing.

Where necessary, we process the adult caregiver’s contact and representation details under Article 6(1)(f) GDPR. Our legitimate interests are participation managed by a legal representative, secure communication and the protection of minor participants. The data is limited to the details needed for these purposes and is not published in fellow-player views.

Preventing misuse and documenting confirmed declarations are based on Article 6(1)(f) GDPR. Legitimate interests are protecting accounts and the service and ensuring that participation and representation details can be traced. We take particular account of children’s protection and limit the scope, visibility and storage of data to the respective purpose.

Messages, hosting and technically necessary functions

Confirmation links, new game proposals, status changes and scheduled reminders are sent to the account’s own email address; for children’s accounts, to the adult managing the account. The extension does not disclose email addresses to other players. It has no chat, sends no booking requests to venues and does not book courts. A reservation report is information supplied by whoever sent that proposal. David also receives notifications of newly confirmed participation and changes to flexible game proposals. Details are available in the private administration overview.

The installation uses the existing STRATO web hosting. WordPress sign-in and security functions require technical session data and functional cookies. The partner matching extension contains no advertising tracker of its own. Its images and font files are served by the website itself. Hosting and email services may process technical data when pages are accessed and messages sent. When contacting the provider by email, the information about Outlook.com/Microsoft in the general privacy policy also applies. This statement concerns correspondence with the provider and does not describe every participant’s email provider.

To protect the registration form, we limit confirmation requests per email address, per internet address and overall. For this purpose, identifiers calculated from the IP address using a secret key are stored, rather than plain-text IP addresses in our own form counter. These identifiers remain personal data. The counter protects only our registration form, not all WordPress sign-ins or password resets.

Retention and deletion

Unused confirmation links remain valid for a maximum of 24 hours. They cannot be used afterwards; technically expired entries are removed by WordPress cleanup. This also applies to participation and parent details temporarily stored before confirmation. Email-address request counters expire after five minutes; IP-related and global counters expire ten minutes after the last accepted request.

Profiles, parent and age details and participation confirmations are stored for the duration of the participation provided. You may end participation or request deletion at any time. On request, matching data is removed through the privacy tools and affected active proposals are closed. Deleting a WordPress account is a separate process, so ending matching does not remove other account functions without being asked.

Game proposals are removed from the matching records 30 days after the proposed game ends, regardless of status. Cleanup runs during matching operations or through WordPress cron. If there are no visits or cron is not running, actual removal may be delayed. Invalid historical dates are retained for investigating errors.

Deleting data on the website does not remove delivered emails from participants‘ mailboxes. Completed contact enquiries to the provider are subject to the three-month period after completion specified in the general privacy policy, unless further lawful retention is necessary. Hosting logs and backups follow the agreed hosting retention periods and backup cycles. Removal from active matching records does not automatically delete every existing backup.

Your rights

Subject to the statutory requirements, you have rights of access, rectification, erasure, restriction and data portability. For processing based on Article 6(1)(f) GDPR, you may object on grounds relating to your particular situation. An objection will be assessed taking the specific circumstances into account. Where processing relies on separate consent, you may withdraw it for the future.

Send requests to davidschtennis@outlook.com. WordPress privacy tools allow your own matching data to be exported and removed. For children, the legal representative submits the request; children retain their own data protection rights. The website needs the stated mandatory details to associate participation and calculate suitable proposals. Without them, this matching service cannot be used.

You may lodge a complaint with a data protection supervisory authority. For private businesses in Bavaria, the Bavarian State Office for Data Protection Supervision is one point of contact.

A simple explanation for children

We store your first name or nickname, age group, playing level and, if you wish, general time preferences. You agree on a specific date on the website only after searching for partners. Your parent manages the account and receives the emails. Other players see only what they need for the shared game proposal. They cannot see your parent’s name or your email address. If you have questions or no longer want to take part, speak to your parent or write to David together.
