⭐ PLUME+ (optional)
━━━━━━━━━━━━━━━━━━━━
Your first 3 documents each month are free, and the batch comes back on the 1st. To sign as much as you want: a 1-month pass (one-time purchase, no auto-renewal), an annual subscription, or a lifetime license with a single payment. The pass doesn't renew: nothing to cancel. The annual subscription can be cancelled anytime from Google Play → Payments & subscriptions. No account required in the app; one-tap purchase restore.

Plume is built for freelancers, parents, tenants, associations — everyone who signs contracts, leases, quotes or consent forms and refuses to send their documents to someone else's server.

📥 Download Plume and sign your first document within the minute.
