Every field, one by one

Field	What it holds	Can identify you?
`Field`	What it holds	Contains anything identifying you?
`prompt`	The text you sent, cleaned and truncated.	No
`response_a / response_b`	Both model replies, in full.	No
`model_a_id / model_b_id`	Which models answered. Hidden from you until after you vote.	No
`winner_id`	Which side you chose, or null for a tie.	No
`both_bad`	1 when you flagged both responses as unusable.	No
`category`	The prompt category, from a fixed list.	No
`temperature / max_tokens`	The sampling settings the battle ran under.	No
`style_preset / style_prompt`	The style you chose. Your own words, so treat it as yours.	Yes, if you typed it
`client_ip`	Your IP address at the time of the vote. Truncated to 45 characters.	Yes
`vote_feedback`	Why you picked that side, from a fixed list of reasons.	No

What is never collected

No accounts, no login, no email address.
The application sets no cookies of its own and runs no analytics. The reference pages (this one, blog, FAQ, About, leaderboard) load a third-party ad tag; the battle, comparison, direct chat, shared battle and admin pages load no third-party JavaScript at all.
No prompt is shared with anyone for any purpose other than calling the two models.
The model provider does receive your prompt and the conversation history, because that is what answering it requires.

Getting the data out

Everything lives in one SQLite file, so an export is a file copy. Stop the web server first, or copy the file and the -wal and -shm files beside it.

# a consistent snapshot
sqlite3 database.db ".backup 'arena-snapshot.db'

# or the schema and rows as SQL
sqlite3 database.db .dump > arena.sql

# just the votes
sqlite3 -header -csv database.db \
  "SELECT id, model_a_id, model_b_id, winner_id, both_bad, category, temperature, voted_at FROM votes"

To drop everything and start over, delete database.db and reload schema.sql. To upgrade an existing database instead, run php migrate.php.
