Privacy notice
Privacy, public play and football data
This notice explains which personal data the game uses, why it is needed, what becomes public and how to request access, correction or deletion.
Account and game data
What the game stores
The game stores your username, a securely hashed password, fantasy-team name, squad, line-ups, transfers, chip choices, scores and gameweek history. It also stores the session and security information needed to keep you signed in and protect forms.
Technical data
Logs and essential cookies
Requests can create security and diagnostic logs containing an IP address, request path, time, response status and browser information. Essential session and CSRF cookies support login and protect account actions. The game does not use advertising or analytics cookies.
Public visibility
What anyone can see
Leaderboards and public team pages are available without signing in. Your username, fantasy-team name, points, rank, transfer costs, chip use and locked gameweek selections can therefore be viewed by anyone on the internet.
Your password and selections that have not yet been locked for a gameweek are not published. Choose a nickname and team name that do not reveal information you want to keep private.
Purposes
Why the data is used
Personal data is used to create and secure accounts, operate the fantasy competition, enforce deadlines, calculate and publish results, investigate faults or abuse, maintain backups and respond to account requests.
Hosting
Who processes the data
Render provides the application hosting, managed PostgreSQL database, network delivery, service logs and backups as a processor for the operator.
The configured hosting location is Frankfurt, Germany. Data may therefore be processed outside Switzerland when that location is abroad, subject to Render's contractual terms and the safeguards required by applicable data-protection law.
No advertising, analytics or third-party error-monitoring service is enabled.
Retention
How long data is kept
Account and fantasy-game data is retained while the account exists. Application logs are retained for up to 30 days. Database backups are retained for up to 90 days, so deleted information may remain in protected backups until those backups expire.
Limited records may be kept longer when reasonably necessary to investigate abuse, protect legal claims or meet a legal obligation.
Your rights
Access, correction and deletion
You may ask for access to your personal data, correction of inaccurate data, deletion of your account or a portable copy where applicable. Send the request to the privacy contact above. The operator may ask for information needed to verify that the account belongs to you.
Deleting an account removes its active profile and fantasy records. Copies in backups disappear within the backup-retention period unless continued retention is legally required.
The football data
Where match information comes from
The player pool, schedule and scoring record are assembled from football-data sources that are separate from account data.
- Players and squadsTransfermarkt.ch is used as a reference for player and club information.
- Fixtures and official resultsSwiss Football League publications are the reference for the schedule and official results.
- Match events and statisticsThe configured SFL feed and, when explicitly enabled, Sportmonks provide match statistics used for fantasy scoring.
Line-ups, assists and statistics may be corrected after the final whistle. Fantasy points can be recalculated to follow the final published record.
These services retain their respective data and brands. They do not operate, sponsor or endorse this game.
Independent project
Made by supporters, not the league
Challenge League Fantasy is an unofficial, non-commercial fan project. It is not affiliated with the Swiss Football League, its clubs, Transfermarkt or Sportmonks. Third-party football data may be delayed, corrected or incomplete.
