Beta privacy information

Updated November 2026. BondStreak is currently a free, limited private beta. You may use a sample-only demonstration without registering. With a verified email/password account, you may save nicknames, bond holding amounts, draw-eligible amounts (if known), winnings and optional winning bond numbers. Do not enter your NS&I login, account number, full legal name or bank credentials.

Technical operation

The website is hosted on Firebase Hosting, a Google service. As with most websites, the hosting provider may process technical request data such as IP addresses to deliver the service and maintain security. Firebase Authentication is used for login and password reset; Google Cloud Firestore stores each account's records with per-user access controls. We do not currently run advertising analytics or payment processing, and no card details are requested.

Your data and control

Your saved data is retained while your account is active. You can export JSON or CSV from Data & help and permanently delete your account and saved records there. Password reset and verification emails are sent by Firebase Authentication. We will update this notice before paid launch with verified contact details, retention practices and any relevant processing information.

Contact for the closed beta

For privacy questions not resolved by your account controls, contact the beta organiser who invited you. The operator's full identity and a direct privacy contact must be published before inviting external testers to enter personal data.
