Your balance protects you.
So it never leaves you.
Alertproof works because nobody else knows your balance. Sending your alerts to someone else’s server would give away the very thing that protects you. So we don’t.
Stored on your device only
Your account number, balance and alerts live in your browser’s storage on your own phone or laptop. There is no Alertproof account and no Alertproof database.
AI that runs at home
With Gemma on your laptop, alerts are read on your machine and never cross the internet. It even works with your data switched off.
We never touch money
Alertproof can’t see your bank account, can’t move money, and never asks for your PIN, password, BVN or OTP. Anyone who asks for them is not us.
If you use online Gemma
On a phone without a laptop, Alertproof can send the text of one alert (or one screenshot) to Gemma hosted by Google, through our small server function. The function passes it through and keeps nothing: no logs of alert text, no database. Your balance chain and book still stay on your phone. You can switch online reading off in Setup at any time.
What Alertproof can’t protect against
- Someone who has seen your latest alert knows your balance. Don’t show your alerts to customers, and don’t post them in group chats.
- A missed alert (a charge, a debit) breaks the chain. Alertproof says so and asks you to set your balance again. It doesn’t guess.
- Reversed transfers. A real transfer can occasionally be reversed by a bank later. Alertproof proves the alert is real, not that a bank won’t reverse it.
Open source, so you don’t have to trust us
Every line of Alertproof is public under the MIT licence: the rules, the prompts, the tests and the evaluation. Read the code on GitHub.
