Your book stays yours.

Access

• Invite-only. Every account is approved by us; sign-in is by single-use, time-limited email links. No passwords to leak.
• Sessions are bound to secure, HTTP-only cookies on app.investrejo.com. The research API is not reachable from the internet; only the application server talks to it.

Your positions

• Positions you enter in Book X-ray are visible only to your account. They are not shared with other users, not used to train models, and not written to logs.
• You can delete your positions, or your account and all its data, at any time.

Infrastructure

• Hosted on a dedicated server in the European Union. All traffic is encrypted with TLS; HSTS is enforced.
• Nightly encrypted backups with seven-day retention.
• This website uses no cookies and no third-party trackers; page views are counted on our own server without identifiers.

Research integrity

• Every claim keeps its verbatim quote and source link. Supplier relationships are marked verified only when we opened the source page ourselves.
• We do not bypass access controls on third-party websites. Where a site refuses automated access, the relationship is shown as cited, not verified.
• We publish the calibration and track record of our own methods, including results that did not work.
