Privacy Policy

1. What we process

The Service has no sign-up, no personal forms and no account system. We only process what is strictly necessary to operate the site:

• League of Legends game data — a pseudonymous player identifier (PUUID), in-game Riot ID, region, current rank and LP, and ranked match history for the last 60 days (champion pool, score, role, items, runes). This data is obtained from the public Riot Games API and cached on our backend.
• Language preference — your chosen UI language is stored in the i18n_redirected cookie. It is essential and used only to keep the language switcher consistent between visits.
• Server technical logs — your IP address and User-Agent are recorded by our hosting provider (Vercel) for rate limiting and troubleshooting.

2. Purposes and legal basis

Game data is displayed to power rankings of one-trick players, their statistics and builds. The legal basis is our legitimate interest in offering an analytics service on top of public game data that Riot Games itself makes available through its API and official clients.

The language cookie and server logs are processed on the basis of our legitimate interest in keeping the Service operational and secure.

3. Third parties

We do not sell your data and do not share it with advertising networks. The Service relies on the following processors:

• Riot Games, Inc. — source of game data. Our backend is the only party that talks to the Riot API and no visitor identifiers are forwarded in those requests.
• Vercel Inc. — hosting for the frontend and the backend API. Vercel retains technical logs (IP, User-Agent, request path) for a short period.
• Neon (Neon Inc.) — managed PostgreSQL where we cache game data. The database is hosted in the EU (eu-central-1).

4. Cookies

The Service currently uses a single essential cookie, i18n_redirected , to remember your chosen language. It does not track you and is not shared with third parties. You can delete it via your browser; on the next visit the site will fall back to the default language (English).

We may introduce web analytics in the future. If we do, we will update this policy, name the provider and, where appropriate, add a consent prompt before any non-essential cookies are set.

5. Data retention

• Match data is stored on a rolling 60-day window and is automatically replaced by newer matches.
• A player snapshot (Riot ID, region, rank, LP) is refreshed periodically and stored as a single current value — we do not keep a history of previous snapshots.
• Technical Vercel logs follow the provider’s retention (typically up to 30 days).

6. Your rights

Because the Service works with pseudonymous public game statistics, most visits do not involve processing of data that uniquely identifies you as a private person. That said:

• If you are a LoL player whose Riot ID appears in the Service, you may ask us to delete your data from our cache by writing to [CONTACT_EMAIL].
• You may request a copy of data we hold about you.
• Please note: deleting data from our cache does not delete it from Riot Games — that is only possible via Riot Support.

7. Children

The Service is not directed at people under 13, and we do not knowingly collect data about children. If you believe a child’s data is present in our cache and should be removed, please contact us.

8. International transfers

Our processors (Vercel, Neon, Riot Games) may handle data on servers outside your country. We pick providers that publicly commit to mainstream data-protection standards.

9. Changes to this policy

We may update this policy. The “Effective” date at the top of the page always reflects the current version. We will try to mark material changes prominently.
