About Flex Exchange
Built by engineers for everyday traders. No fluff, just the parts that matter.
What we do — today
- Spot trading with a straightforward, engineering-first stack.

- Plain fees. No hidden “gotchas” in the UI. What you see is what you trade.
Principles that guide our work
Privacy by default
Authentication uses server-side sessions, not tracking cookies. We avoid collecting data we don’t need.
Clarity over marketing
Pages and dialogs are written to be understood. If something affects your funds, we say it plainly.
Operational transparency
Status updates and maintenance notices go out on our official channels so everyone gets the same info.
Built for everyone
We aim for tools that are useful to newcomers and power users alike—without gatekeeping.
How sessions work (no cookies)
Your login is maintained with short-lived server-side session IDs transmitted over HTTPS. We don’t rely on browser cookies for authentication. If a session looks idle or risky, it’s rotated or ended.
Security at a glance
- Encryption in transit (TLS) and restricted access to production systems.
- Separation of duties and least-privilege for services that touch funds.
- Optional two-factor authentication for accounts that enable it.
What we won’t claim
- No guaranteed returns, VIP shortcuts, or special treatment.
- No promises about unshipped features or timelines.
- We will never ask for your seed phrase or private keys.
- We don’t DM first. If someone does, assume it’s not us.
