We collect only your email address, registered tickers, your time horizon selection, your display language, and the timestamps of those settings. We never collect payment details, your name or address, IP address logs, or cookie-based tracking. We never share or sell your personal data to third parties.
Data is stored in AWS's managed database (DynamoDB); nobody without your invite token can access it. That said, this is a personal project and has not undergone a large-scale security audit. No passwords or other sensitive credentials are required — your email address alone is enough to use the service.
We may show non-personalized ads or affiliate links on the site in the future, but even then we will not deliver ads that identify or track individuals.
This service is intended for residents of Japan and the United States. Residents of the EEA, UK, and Switzerland are not supported.
You can delete your registration data yourself, instantly, at any time via your access link ("Delete account" on the main screen). If you've lost your access link or have another disclosure request, please reach us via the contact form.
