Data collected

Account: email address and password (stored encrypted, never in plain text).
Trading journal: trades, notes, strategies, replay sessions and any content you enter in the app.
AI assistant: the messages you send to the assistant and the generated answers.
Audience measurement: anonymous visit statistics (Vercel Analytics, cookieless).
Product usage: the key steps of your journey in Kova (sign-up, first trade, import, upgrade to a paid plan), linked to your account, to improve how new members are welcomed. This data is never shared.
Files sent to support: when an import fails, the file you choose to send to the Kova team, so we can adapt the import to your format. It's deleted as soon as your request is handled, 30 days after sending at the latest.

Purposes

This data is used only to provide the service: display your journal and statistics, generate AI analyses, apply your plan's quotas and improve the product. Your data is neither sold nor rented to third parties.

Processors

Supabase Inc. — database and authentication.

Your data is kept as long as your account is active. Deleting your account deletes all associated data.
