Every data flow
| What leaves the device | When | Kept? | Linked to a person? |
|---|---|---|---|
| Chess positions and search settings for analysis | Server or community-node analysis | No — processed in real time; node operators must not keep them | No |
| Finished game reviews and position evaluations (moves and evaluations only) | Review with a server access token | Yes, in the shared review store until evicted | No — keyed by a hash of the game |
| Daily usage counters of a player token (searches, engine time) | Analysis with a node or pool token | 90 days | Pseudonymous — the token, not a person |
| Nickname and moves of a friend game | Play a friend via a link | Server memory only, minutes to hours | No |
| IP address in the web server access log | Every connection | [14 days — OWNER: confirm], for security only | No; never used for location or profiling |
| lichess / chess.com username, lichess login | Import or lichess features, sent directly to lichess or chess.com | Not by DaisyChess | — |

- Contact info, health, financial info, location, sensitive info, contacts, browsing and search history, identifiers, purchases, diagnostics.
- Notes
- Positions sent for live analysis are processed in real time and not retained, so they are not “collected” in Apple's sense. The app uses only HTTPS, so it qualifies for the standard encryption exemption (no proprietary cryptography).
