5. Confidentiality and Data Handling.
Draft v3 · Reviewed by Legal · 2024-09-12
Each party shall maintain the confidentiality of all proprietary information disclosed by the other under this Agreement. The receiving party agrees to limit access to confidential material to employees and contractors with a demonstrable need to know, and to apply the same standard of care it uses for its own confidential information of like importance.
The indemnification provisions in Section 8.2 apply to any breach of this clause.1
Data Processing
Customer data covered by this Agreement is processed in accordance with the Data Processing Addendum dated September 1, 2024. Service Provider may engage subprocessors at its discretion. Subprocessor changes require thirty (30) days written notice.
For the avoidance of doubt, this Agreement does not transfer ownership of any data, model weights, or training artifacts to Service Provider.2
Renewal
This Agreement renews automatically for successive one-year terms unless either party provides written notice of non-renewal at least sixty (60) days prior to the end of the then-current term.
Most PDF tools treat your documents like leverage — upload gates, watermarks, accounts, and subscriptions. Open Satchel treats them like your files. Because they are.
01
Files live in your filesystem. We open them on your machine. Nothing about normal PDF editing needs an internet connection.
02
Text edits, page operations, redaction, forms, signatures, and export workflows are built for real PDFs instead of teaser-mode demos.
03
The public editor is free under AGPL. Organizations that need non-AGPL terms, signed builds, support, SDK, source, or OEM rights can license those separately.
01FILESYSTEM
Open Satchel reads PDFs from your disk and saves edited PDFs where you choose. There's no library, no inbox, no walled garden. Move a file in Finder, it moves in Satchel. Delete it in the terminal, it's gone — no orphaned cloud copy to clean up later.

No telemetry. No “anonymous usage data.” No account. No cloud sync. No AI features that require sending your contracts, your manuscripts, or your medical records to someone else's server. The app works the same with the network unplugged.

05QUESTIONS, ASKED
Is there really no cloud component at all?
Correct. The app makes zero outbound network requests in normal operation — not even for “checking for updates” unless you explicitly trigger it. You can verify with Little Snitch, tcpdump, or your firewall of choice.
How do I sync files between devices, then?
However you sync the rest of your files: iCloud Drive, Dropbox, OneDrive, Syncthing, git, a USB stick, or nothing at all. Open Satchel does not need an account system to edit a PDF.
What about iOS or Android?
Not for V1. The launch target is the desktop editor first: macOS, Windows, and Linux.
Is the app open source?
Yes — Open Satchel is licensed under the GNU AGPL-3.0-only, an OSI-approved copyleft open-source license. A separate commercial license is available for organizations that need rights AGPL doesn't grant (closed-source embedding, private modifications, procurement / support agreements).
Will edited PDFs work in Acrobat / Preview / etc.?
The goal is standard PDFs that open in normal readers. Some advanced workflows have known limitations, and those are documented honestly instead of hidden behind marketing copy.
Who makes this?
Open Satchel is built in Kingston, Jamaica. We started it out of a stubborn dislike of PDF tools that treat local documents like bait.
Because it is. Open Satchel V1 is a free local-first PDF editor for macOS, Windows, and Linux. Commercial licensing is available for organizations that need non-AGPL terms, SDK/source access, OEM rights, signed builds, procurement docs, or support.
