Racket is a Telegram Mini App for running and playing racket-sport tournaments (badminton, tennis, padel). This policy explains exactly what we store, why, on what legal basis, and how to get it deleted.
Who is responsible for your data
The data controller is IP Efremova A. V. (an individual entrepreneur registered in Russia), the operator of Racket ("we", "us").
- Email: club@badmclub.ru — use this for any privacy request. It works even if you have deleted your Telegram account.
- Telegram (fastest): @racket_app_bot —

What we collect, why, and on what legal basis
We do not ask you to create an account or a password. You sign in with Telegram, and we receive only what Telegram passes to a Mini App. "Legal basis" below refers to Article 6 of the GDPR, for users to whom it applies.
| Data | Why | Legal basis |
|---|---|---|
| Telegram user ID, username, name, profile photo | To identify you, show you in draws and standings, and send you tournament notifications | Contract — performance of the service you asked for (Art. 6(1)(b)) |
| Language | To show the app in your language | Contract (Art. 6(1)(b)) |
| Optional profile you fill in yourself: city, gender, age, playing level, playing hand | To seed draws fairly and help organisers group players. All optional — leave them blank and the app still works | Contract (Art. 6(1)(b)) |
| Your tournaments, registrations, match results and rating | This is the product: brackets, standings and ratings cannot exist without it | Contract (Art. 6(1)(b)) |
| Venue location you enter — the venue name, address and the map coordinates (latitude/longitude) you pick for a tournament | To show other players where the tournament is played. This is the venue's location that an organiser chooses on the map — not your device's location. Racket never asks your browser or phone for your position and never tracks where you are | Contract (Art. 6(1)(b)) |
| Telegram Stars purchases (charge ID, amount, tier, refund status) | To grant the cosmetic Profi badge, to honour refunds, and to keep the accounting and tax records we are required to keep | Contract (Art. 6(1)(b)) for granting the badge; legal obligation (Art. 6(1)(c)) for retaining the payment record for accounting and tax duties |
| IP address and request logs — IP, timestamp, user agent, the request made — processed by our hosting provider Cloudflare | Unavoidable in serving any web request. Used to keep the service up, block abuse and attacks, and debug errors | Legitimate interest (Art. 6(1)(f)) — securing and operating the service |
We do not collect your phone number, email address (unless you write to us), contacts, or payment card details, and we do not collect your device's GPS or browser geolocation. We do not use advertising or analytics trackers, and we do not sell or profile your data.
Payments
The optional Profi and Profi Trainer badges are bought with Telegram Stars. The payment is processed by Telegram — we never see or store card details. We store only the charge identifier Telegram returns, the tier and the amount, so we can grant the badge, refund it if you ask, and satisfy our accounting duties.
Who we share it with
We do not sell your data and do not share it with advertisers. It is processed only by the infrastructure that runs Racket:
- Telegram — sign-in, notifications, and Stars payments (Telegram's Privacy Policy)
- Cloudflare — hosting, application logic, database and request logs (Cloudflare's Privacy Policy)
Other players see what you would expect them to see in a tournament: your name and photo, your registrations, your results and your rating. A tournament's venue and map pin are visible to anyone who can see that tournament.
International transfers
Racket runs on Cloudflare's global network and Telegram's servers, so your data is processed on servers outside the European Economic Area, including in the United States. Where personal data of EEA/UK users is transferred, it is covered by the Standard Contractual Clauses adopted by the European Commission, which our providers incorporate into their data-processing terms.
How long we keep it
- Your profile: while you use Racket, and then for up to 24 months of inactivity (no sign-in, no registration, no match). After that it is deleted automatically, on the same anonymise-and-detach basis described below.
- Tournament results and ratings: kept for as long as the tournament record exists, because a bracket with players removed is no longer a truthful record of what happened. After your deletion your entry appears anonymised (see below).
- Stars payment records: retained for 5 years after the transaction, because accounting and tax law requires it. They survive account deletion, but hold nothing beyond the charge ID, tier, amount and date.
- Cloudflare request logs: short-lived, retained by Cloudflare per its own policy (days, not years) and used only for security and debugging.
Your rights
You can ask us to:
- Access a copy of your data, and port it — receive it in a structured, machine-readable format (Art. 20)
- Correct anything inaccurate
- Delete your account (see below)
- Restrict processing, or object to processing we carry out on the legitimate-interest basis — that is, the security and debugging logs (Art. 21)
Write to club@badmclub.ru, or message
@racket_app_bot with /support. We answer
within 30 days and charge nothing.
If you believe we have handled your data wrongly you have the right to lodge a complaint with a supervisory authority — in the EEA, the data protection authority of the country where you live or work (list of authorities); in the UK, the ICO.
Deleting your account
You can delete your Racket account at any time:
- in the app: Profile → Delete my account, or
- by email to club@badmclub.ru, or
- by sending
/supportto @racket_app_bot.
Deletion is anonymise-and-detach: your profile — name, username, photo, city, gender, age, level, playing hand — is removed, and you are detached from your registrations. Where a completed tournament's record must stay intact, your entry is anonymised rather than erased (it shows as a former player with no identifying details), so the bracket and other players' results remain correct. Stars payment records are kept for the legally required period as described above. The deletion cannot be undone; signing in again creates a fresh, empty account.
Children
Racket is not directed at children. You must be at least 13 years old to use it — or 16, if the law of your country sets a higher minimum age for consent to online services. If we learn that a younger child has an account, we delete it. Telegram's own minimum age also applies.
Changes
If this policy changes materially we will update this page and the date above.
