We handle only the information needed to run the journal.

1. Information processed

• Email address, display name, and account identifier from Google sign-in
• Trading records, notes, strategies, and emotional state entered by the user
• Chart images and annotations uploaded by the user
• CSV or Excel data selected for record import
• Connection, error, and device information used for security and service improvement

2. Purposes

• Authentication and per-account record storage
• Trading-journal statistics
• Security, troubleshooting, and product improvement

3. Storage and processors

Member information, trade records, and uploaded images may be stored and processed through Supabase. Guest data remains in browser storage. Vercel is used to deploy and deliver the service.

4. File import

Record import reads the file selected by the user in the browser and converts only values that can be verified. The complete file is not sent to an external AI service without separate notice. If a user chooses an external AI to format a file, that provider’s privacy terms apply.

5. Analytics, advertising, and billing

Vercel Web Analytics is used to understand visits. When advertising is enabled on public guides, Google AdSense may use cookies or similar technologies. AdSense ads are not shown inside the personal journal, trade-entry, sign-in, or checkout screens. Paddle may process information needed for payment, tax, subscription status, and refunds.

6. Retention and deletion

Information is deleted when it is no longer needed or when a valid deletion request is received, unless retention is required by law. Individual entries and all trading records can be deleted in the service. Signed-in users can delete their service account from the profile menu. An active paid Pro subscription must be canceled and reach the end of its paid period first.

Free trials are offered once per Google account. To prevent repeated trials after account deletion and re-registration, a keyed hash of the Google account identifier and trial-use history are retained after deletion while the trial offer remains available. This history does not include trading records or the original email address. Paddle processes the trial subscription and its ending status.

7. Requests

Questions about access, correction, deletion, or account deletion that cannot be completed in the service may be sent to jaeon3214@gmail.com.
