Privacy and security

How Fluxmail protects your email: no stored bodies, encrypted metadata, blocked trackers, and zero-retention AI.

Fluxmail is built so your email stays yours. This page covers what's stored, what isn't, and how the AI handles your mail.

Your email bodies aren't stored on our servers

When you open a message, Fluxmail fetches it from Gmail and caches it on your device for speed and offline reading. The body of your mail is not kept on Fluxmail's servers. The one exception is content you're actively working with, like a draft you're writing or a message queued to send later, which has to be held until it's saved or delivered.

Metadata is encrypted

To keep the app fast, Fluxmail does store some message metadata on its servers, such as subject, sender, and labels. That metadata is encrypted at rest, and we don't read it.

AI that doesn't keep your data

We only use AI models and providers that have Zero Data Retention, meaning they don't keep your data or train on it.

Trackers are blocked

Plenty of emails have tracking pixels that report back to the sender when and where you opened them. Fluxmail blocks these by default, so nosy people can't snoop on you while you read your email.

Certified

Fluxmail is CASA Tier 2 certified and has passed an independent security review according to Google's strict enterprise-grade security standards.

You stay in control

  • Fluxmail never deletes your mail for you. Sorting, prioritizing, and archiving move things around; they don't destroy anything.
  • Actions that are hard to undo, like trashing or marking spam through Flux AI, ask for your approval first.
  • Your emails stay in Gmail and you can always access them there if you ever decide to stop using Fluxmail. However, you may need to migrate certain things that we store ourselves, like drafts or snoozed emails.
