Security
Your inbox, to yourself.
Read-only, encrypted, and easy to switch off. Here's exactly how we keep it that way.
01
Read-only access
Subzero only requests permission to read. We can't send, delete or change your email.
02
Encrypted, server-side tokens
Access tokens live on our servers, encrypted at rest, and never touch your browser.
03
Minimal data
We keep the fields that make the app work — price, plan, provider, renewal date. Not your inbox.
04
Row-level security
Your data is fenced off in the database. No one else can see it, ever.
05
One-click disconnect
Disconnect and wipe every imported record from Settings whenever you want.
