Privacy Policy
Last updated: 25 August 2026
This Policy explains what data we collect in the Vint Rankapp for iOS and Android and on the vintrank.net website (the "Service"), why we need it, who receives it, and how to delete it. By installing the app or using the website you agree to this Policy.
1. Who processes your data
The Service is run by the Vint Rank team ("we"). We decide why and how your data is processed, which makes us the data controller. You can reach us about anything in this Policy at support@vintrank.net — we reply within 30 days.
2. Data we collect
We collect only what the Service needs to work. There is no "tell us about yourself" form: almost everything below appears as a result of what you do — signing up, playing a match, entering a tournament.
| Category | Data | Purpose |
|---|---|---|
| Account | Email — or your Apple / Google identifier if you sign in with them | One-time-code login, account recovery, contacting you |
| Profile | Name, nickname, photo, city and country, description, favorite club, main discipline; phone number if you provide one | Showing your profile to other players, finding opponents, letting a club reach you about a booking |
| Game data | Rating and league, wins and losses, streak, match history, tournament entries, bookings, Vint balance and history | Running the rating, leagues, tournaments, clubs and wallet |
| Uploads | Profile photo, club photos and description, tournament titles and descriptions | Displaying them where you uploaded them |
| Device | Push token, platform (iOS / Android) and device interface language | Match and tournament notifications in the language you play in |
| Technical | IP address, device type and app version, crash reports | Security, abuse prevention, diagnostics |
| Analytics | Anonymized events: sign-up, match created, tournament entry and similar | Understanding which parts are used, and improving the product |
What we do not collect
- Payment or card data. The app is free, has no in-app purchases or subscriptions, and processes no payments.
- Precise (GPS) location. You choose your city and country yourself and can change them at any time.
- Contacts, messages or gallery contents — other than the photos you pick for your profile or a club page.
- Special categories of data (health, beliefs, biometrics). The Service has no use for them and will not ask.
3. Why we process data
Every purpose has a legal basis behind it:
| Purpose | Data used | Legal basis |
|---|---|---|
| Let you sign in and keep a profile | Account, profile | Performance of the Terms of Service — our agreement with you |
| Run ratings, matches, tournaments and bookings | Game data, profile | Performance of the Terms of Service |
| Send notifications about your matches and tournaments | Device | Your consent — the notification permission, which you can withdraw in device settings |
| Protect the Service from rating manipulation, fraud and attacks | Technical, game data | Our legitimate interest in a fair rating and a working Service |
| Understand how the app is used and improve it | Analytics, crash reports | Our legitimate interest; the data is anonymized |
| Answer your support requests | Account, your correspondence with us | Performance of the agreement and our legitimate interest |
4. Who we share data with
We do not sell your data and do not share it with advertisers. Some parts of the Service are run by processors, which receive only what their task requires and act on our instructions:
- Supabase — database, authentication and storage of uploaded files.
- Google Firebase — push notification delivery, anonymized analytics and crash reporting (Crashlytics).
- Resend — delivery of one-time login code emails.
- Vercel — hosting of the vintrank.net website.
- Apple and Google — if you sign in with their accounts. We receive an identifier and an email address, nothing more.
We also disclose data where the law requires it, or where it is needed to protect the rights and safety of players.
As for what other players see: your public profile — name and nickname, photo, city, rating, league, statistics and match history. Your email, phone number, push token and Vint transaction history are not visible to them. Parts of the public profile, such as your row in the leaderboard, are visible without signing in, including on the website.
5. Where data is stored
The database and uploaded files are stored on Supabase servers in the European Union (Frankfurt, Germany). Push notifications go through Google infrastructure and the website runs on Vercel infrastructure — both are international and may process data outside Kazakhstan, including in the United States.
By using the Service you consent to this cross-border transfer. We pick processors that protect data to the standard required by applicable law and process it only on our instructions.
6. How long we keep data, and how to delete it
While your account exists we keep your profile and game history — without them there is no rating to show and no head-to-head record to build.
You can delete your account yourself at any time: Profile → Settings → Delete account. Deletion happens immediately and cannot be undone:
- the account, including your email and phone number, is deleted — they can no longer be used to sign in;
- the profile is anonymized: name, nickname, photo, city, country, description and favorite club are erased;
- your devices' push tokens, your notification feed and your per-discipline ratings are deleted;
- clubs you owned stay in the catalogue without an owner — a club page describes the venue, not you.
Matches you played and tournament results remain — without your personal data, under an anonymized profile. Removing them would retroactively change your opponents' ratings and the brackets of tournaments that have already been played. Any Vint balance is forfeited on deletion.
Our hosting provider's database backups may hold already-deleted data for a limited time before being overwritten. Technical logs (IP addresses, crash reports) are kept by our processors for a limited period and then deleted automatically.
7. How we protect data
Data is transmitted over an encrypted connection (HTTPS/TLS). Access is restricted in the database itself by row-level security: another player cannot obtain your email, phone number or push token, even by calling the API directly. Ratings are calculated on the server only, so they cannot be changed from the app. Very few people have access to the data.
No service is perfectly secure, so please protect access to the mailbox and the Apple / Google accounts you sign in with.
8. Your rights
- Get a copy of your data and learn how it is processed.
- Correct inaccurate data — name, nickname, city, photo and description are editable right in your profile.
- Delete your account — in the app, as described in section 6.
- Withdraw consent: turn notifications off in device settings, or stop using the Service.
- Object to processing or ask us to restrict it.
- Complain to a data protection authority — in Kazakhstan, the authorised body for personal data protection; in the EU, the supervisory authority of your country of residence.
To exercise any of these rights, write to support@vintrank.net from the address on your account.
9. Children
The Service is not intended for anyone under 13, and we do not knowingly collect their data. If we learn that an account belongs to a child under 13, we delete it. If you believe this has happened, please tell us.
10. Website, cookies and analytics
The vintrank.net website uses strictly necessary cookies only: they store your interface language and your session if you are signed in. There are no advertising cookies or third-party trackers on the site.
We measure site traffic with Vercel Analytics and Speed Insights, which collect anonymized statistics and do not identify visitors. In the app, anonymized events are collected by Firebase Analytics; you can opt out by not using the app.
11. Changes to this Policy
We may update this Policy — for instance when the Service gains new features. The current version is always on this page, with the date of the last change at the top. We will announce material changes in the app.
