## What is Plume?

Sign your PDFs in 3 seconds — no account, no cloud, and your documents never leave your phone.

Plume is the simplest, most private way to sign: open a document, drop your signature, export. That's it. No sign-up, no server, no data collection.

WHY PLUME?

BLAZING FAST
• Your first document is free — no account needed, ever
• Open documents straight into Plume (Files, Mail)
• Draw your signature once, reuse it on every document
• It lands right on the page: drag, pinch, sign

100% PRIVATE, BY DESIGN
• Zero account, zero sign-up, zero cloud
• Your documents and signature NEVER leave your device
• No trackers, no ads, no analytics
• Photo signature background removal runs on-device

ALL YOUR FORMATS
• PDF, Word, Excel, images and text — converted to PDF on-device
• Automatic drafts: leave and pick up exactly where you were
• Optional certificate page attached to your signed PDFs
• Search, filter and share your signed documents

YOUR SIGNATURE, THREE WAYS
• Draw it with your finger — smooth, natural ink
• Type your name, styled in cursive
• Photograph it — the background is removed automatically

PLUME+ (optional)
Your first document is free. 7-day free trial on the annual subscription. To sign without limits: a monthly or annual subscription (best value), or a lifetime license. Cancel anytime in your App Store account settings. No in-app account required; one-tap restore.

Plume is built for freelancers, parents, tenants and small teams — everyone who signs contracts, leases, quotes or permission slips and refuses to upload them to someone else's server.

Download Plume and sign your first document within the minute.
