Privacy
You can read everything here without an account, and the default reading experience works without any personal data.
Anonymous by default
Reading is anonymous. Preferences such as reading depth can stay in your browser only. Where a session is used for optional features, it exists to serve those features, not to build a profile you did not ask for.
You control optional features
Optional measurement is off unless you allow it, and performance timings carry no question text, no selected text, and no addresses. Settings and account surfaces let you review and change these choices at any time.
Retention is bounded and stated
Operational records have explicit retention bounds: performance samples and assistant interactions are short-lived, and reader reports are kept only as long as a correction or response process needs them. Free text in reports is redacted before storage.
