# Privacy information — NUMO DUEL

Source: http://localhost:3000/privacy/

This Markdown companion summarizes the current product's data handling and is **not a substitute for a legally reviewed operator privacy policy**.

## Local practice

Local game preferences, practice history, progress and achievements can be stored on your device. Clearing browser/app storage can remove this information.

## Online accounts and matches

When configured, account access uses Supabase Auth with persisted session and refresh tokens. Optional email-based account features depend on the Supabase provider configuration. Authenticated multiplayer results and ranking statistics use a connected backend and Supabase PostgreSQL. Local solo or AI sessions do not become verified global ranking results.

## Avatars

The game can generate a processed illustrated avatar from a selected image. When cloud avatar storage is available, the processed image may be stored privately and shown to current opponents or as part of an opted-in public profile. Original selected photographs are not meant to be uploaded as profile images.

## Controls and deletion

Players can edit visible profile details and some privacy preferences, reset or export local data, and access account deletion in the app. Deletion requirements may depend on outstanding matches and backend configuration.
