Information we collect
We store your email address, sign-in sessions, subscription identifiers and status, watchlists, notification destinations, API key hashes and usage counters. We also store research preferences, saved screens, AI requests and results, custom prompts, team memberships and invitations, and support messages you submit.
Stripe collects and processes payment details. Tokyo Tape stores billing identifiers and subscription status, not full card numbers. Public filing information comes from EDINET and may contain information about filers and holders.
How we use information
We use this information to authenticate you, provide research and team features, send requested notifications, process subscriptions, respond to support requests, prevent abuse and diagnose service failures.
Service providers and destinations
Microsoft Azure hosts the application and backups in Japan East. Resend delivers email using its Tokyo sending region. Stripe processes billing. Providers may process operational or account data in other countries under their own terms.
AI features use Anthropic Claude. Filing excerpts and your research question or screening request are sent for processing. Do not include confidential information or personal information that is unnecessary for the research request.
If you configure Slack or a webhook, requested filing notifications are sent to that destination. People who control or can access that destination may see them.
Optional sign-in methods
If you choose Google or Apple sign-in, we receive your provider account identifier, email address and any profile information you share. The provider processes your sign-in under its own privacy policy. Accounts are linked only after you sign in to your existing Tokyo Tape account.
For passkeys we store the credential identifier, public key, device metadata and usage counter. We do not receive your fingerprint, face scan or device PIN. You can remove registered passkeys in Account settings.
Cookies and security
We use cookies for sign-in and security, and local browser storage for your theme preference. Access to the production host and backups is restricted; connections use HTTPS, and backup storage is encrypted. No system is entirely risk-free.
Retention and deletion
Account settings and research history are retained while your account exists. You can remove notification channels and request account deletion from Settings. Active subscriptions must be ended before account deletion. Deletion removes your application account and associated records; it does not erase independent provider records needed for billing, disputes or legal obligations.
Backups are separate from the live database. Azure backup objects expire after 30 days and may remain recoverable for a further 7 days under soft deletion. Deletions must be reconciled before a backup is restored to live service.
Your choices
You can manage alerts and unsubscribe from alert emails. To request access, correction, deletion or a restriction of personal information, email takahashi@layersecurity.jp. We may ask you to verify ownership before acting. Rights required by applicable law are preserved.
Updates
We will update this page when our practices change and provide notice of material changes where required.
