Beta terms

Updated November 2026. BondStreak is a free, experimental beta. The demonstration uses fictional sample amounts. Registered users may store their own manually entered draw history. Do not rely on calculations in BondStreak alone when making financial decisions.

Not an official service

BondStreak is not affiliated with, endorsed by, or operated by NS&I. It does not automatically check prize results or provide financial advice. Premium Bonds results, terms and draw eligibility must be verified with NS&I.

Your inputs

The unauthenticated demo is temporary and resets when reloaded. Verified beta accounts can save data with Firebase. You are responsible for the accuracy of entries and backups; the product is provided as-is during testing. Never enter bank or NS&I login credentials.

Future subscriptions

No subscriptions, payment collection or paid features are active in this beta. Commercial terms will be published separately before offering a paid service.
