Acier was designed from day one so your inventory stays yours. It lives on your iPhone and in your own iCloud account, and we do not keep a copy.

/// Core Principles

Four commitments built
into how Acier works.

P.01

Your inventory stays with you

Everything you catalog lives on your iPhone and in your own iCloud account. Acier does not keep a copy on its servers, so there is nothing of yours for us to read, lose, or hand over.

Any time, any plan
P.02

Photos analyzed, not stored

When you ask Acier to identify an item, the photo travels over an encrypted connection and is analyzed. Acier never stores it on our servers, and it is never used to train a model.

P.03

Your policy, redacted first

Before a policy is read, Acier looks for the insured's name, street addresses, and dates of birth and removes them on your phone, on scanned and photographed pages too. A page it cannot check is never sent. The PDF itself stays on your device, and the Underwriter Agent conversation is kept there too.

No always-on cameras

Unlike security camera systems, Acier only uses your camera during scans you start. No background recording, no live feeds, no cloud-stored footage. When you're done scanning, the camera is off.

/// Operational Practices

Beyond architecture,
the day-to-day discipline.

01 / 06

Sign in with Apple

No password to create, reuse, or leak. Apple handles sign-in, and you can hide your email with a relay address.

02 / 06

Face ID lock

Turn on Face ID or Touch ID to lock the app. Biometrics are handled by Apple on your device; Acier never receives them.

03 / 06

Approximate location only

Our servers round your property's coordinates to about 100 meters before any flood, wildfire, or earthquake lookup. The Underwriter Agent gets only your city, state, and ZIP code, never your street address.

04 / 06

Regular security reviews

Code-level security audits before releases, covering sign-in, account separation, and how AI requests are handled.

05 / 06

Token rotation

Sessions use short-lived tokens with automatic refresh-token rotation, so a stolen token expires quickly and cannot be reused.

06 / 06

Account deletion

Delete your account in the app and the records we hold on our servers are permanently removed within 30 days. Apple purchase ids are kept, with no link to your account, so a purchase is never credited twice.

/// A Different Posture
