Privacy policy | TKDchecker

Who we are

TKDchecker.com is part of the Beltchecker network of sites, where martial artists list their rank and training history and the community helps verify it. This policy explains what personal data we collect, why, who helps us process it and what your rights are.

The Beltchecker sites are run by Globetrotters Sports ApS, a Danish company (CVR 45285103), which is responsible for your data.

Questions or requests about your data: write to [email protected].

What we collect

Account details: name, nickname, email address, birth date, gender, country and city, and your login history.
Your profile: profile picture, rank and promotion history, academies, instructors, competition results, training notes, attendance and anything else you add.
Verification uploads: a selfie holding a handwritten note, and a photo of a document that shows your name.
What you do on the site: votes on profiles, forum posts, messages, comments and likes.
Orders: what you bought, your shipping address and the payment status. Card details go straight to the payment provider; we never see or store them.
Technical data: IP address, browser and device type, and pages visited, kept in server logs and used for security and statistics.

What is public

Beltchecker is a public register. Your name, profile picture, rank, promotion history, academies and verification status can be seen by anyone and found by search engines. So can votes on profiles and forum posts. Messages are private between you and the recipient. Verification uploads are never public.

Why we use it

To run your account and show your profile (our agreement with you).
To verify ranks and identities and keep fake profiles out (our legitimate interest, and the purpose of the service).
To deliver orders such as certificates and ID cards, and to keep the records bookkeeping law requires (agreement and legal obligation).
To send login codes, notifications and, if you have not opted out, news from Beltchecker (agreement and legitimate interest; you can switch emails off in your settings).
To keep the site secure and understand how it is used (legitimate interest).

Verification and AI

Verification uploads are checked by our moderators. To help them, each upload is also checked by an AI service (Anthropic's Claude), which compares your selfie with your profile picture and reads the name on your document. The AI only gives a suggestion; a person always makes the decision.

Name documents are deleted from our servers as soon as they have been checked. Selfies are kept so moderators can compare later uploads. The AI service does not use your images to train its models and deletes them after a limited time (normally up to 30 days).

Who helps us

We do not sell your data. We share it only with services that help us run the site, and only what each one needs:

OVH: hosts our servers and database (France).
Cloudflare: delivers and protects the site.
Mailgun: sends our emails.
Stripe and PayPal: take payments. Academies that sell memberships on Beltchecker use their own Stripe account.
InstantCard: prints and mails plastic ID cards you order (name, rank, academy, photo and shipping address).
Anthropic: the AI check of verification uploads described above.
Google Analytics and Meta (Facebook) pixel: visitor statistics and measuring our ads.
Progressier: lets you install the site as an app and receive push notifications if you allow them.

Some of these companies are based in the United States. Where data leaves the EU, it is covered by the EU-US Data Privacy Framework or the European Commission's standard contractual clauses.

Cookies

We use the cookies the site needs to keep you logged in, remember your settings and protect forms.

Google Analytics and the Meta pixel, which set cookies for visitor statistics and ad measurement, are only loaded if you say yes in the small cookie box. Your answer is remembered for a year.

How long we keep it

Your profile stays until you ask us to delete it. Name documents are deleted as soon as they have been checked. Order and payment records are kept as long as bookkeeping law requires. Server logs are deleted after two weeks.

Children

Young members can have a profile. To protect them, walls, messages and comments are switched off on their profiles.

Your rights

You can see, correct and download your data, ask us to delete it, object to how we use it, and withdraw consent at any time. Most of your profile can be edited directly in your settings. For anything else, including deleting your account, write to [email protected].

If you think we handle your data wrongly, you can complain to the data protection authority in your country.

Changes

When we change this policy, we update the date at the top. Larger changes are announced on the site.
