About Perma
What is Perma?
Perma is a client-side encrypted cloud storage service with pay-once upload capacity. It provides immutable, write-once storage for personal documents and business archives.
What Perma does
Perma encrypts files in the browser before upload, ensuring that private keys remain stored locally on user devices. Files are saved to WORM (write once, read many) storage, making stored copies immutable so that files cannot be overwritten, edited, or altered. Instead of recurring monthly subscriptions, users prepay for upload capacity at €1 per GB or $1 per GB. Purchased capacity does not expire, and users can share file access through private sharing keys.
Who Perma is for
Perma is designed for individuals and businesses needing long-term archives and ransomware-resilient storage for contracts, records, and personal files without monthly subscription fees.
How Perma works
Users generate a private key on their device, purchase upload capacity upfront, encrypt files locally in the browser, and upload them to immutable write-once storage.
