Harbor Fax VS PrivacyNotes

Harbor Fax's answer

Regular people stuck needing a fax machine in 2026. That means patients sending records to a doctor's office, people dealing with insurance or benefits paperwork, folks handling legal or HR documents, and small businesses that fax occasionally but don't want a full subscription. If you care about where your sensitive documents end up, it's for you.

PrivacyNotes's answer:

People who want their private life in one private place: notes, plans, passwords, a journal and health records. It fits independent professionals who keep sensitive material, such as lawyers, journalists, therapists, doctors, developers, researchers and founders. It also fits anyone who is tired of paying for five apps that each hold one part of their life.

Harbor Fax's answer

Python and Flask for the backend, Telnyx for T.38 fax delivery, Stripe for one-time payments, and ReportLab for PDF handling. It's self-hosted on Oracle Cloud ARM infrastructure behind nginx, with no third-party trackers.

PrivacyNotes's answer:

React, TypeScript, Vite and Tailwind CSS.

Harbor Fax's answer

Harbor Fax doesn't keep your documents. Your file gets sent over T.38, a fax-specific protocol built for reliable transmission, and is wiped once delivery finishes. There's no account to create, no subscription, and no fax history sitting on a server waiting to leak. You pay one flat price per send, and that's the whole relationship.

PrivacyNotes's answer:

PrivacyNotes keeps your notes, tasks, passwords, journal, files, calendar, contacts and bookmarks in one app, with mood and medication tracking. Everything is encrypted on your device with XChaCha20-Poly1305, under a key from a 12-word recovery phrase. Most privacy apps do one of these jobs and charge for it every month. PrivacyNotes does all of them, and Pro is a one-time purchase. The apps are open source, so anyone can check what they do.

Harbor Fax's answer

Most online fax services want a monthly plan for something people do a few times a year, and they hold onto every page you send. Harbor Fax is $2.99 per send with no signup and no recurring charge. It's built for the person who has to fax a medical form, a benefits claim, or a legal document and doesn't want that paperwork stored by a company they'll never use again.

PrivacyNotes's answer:

Three reasons:

• One app, not a stack of subscriptions. Standard Notes, Day One, Daylio and Bitwarden each cover one part of your life. PrivacyNotes covers all of them, with one price, paid once.
• Encrypted on your device. Your notes are always encrypted, on your device and on the way to our servers in Zurich, Switzerland. With self-custody, the server holds nothing that opens your notes.
• Open source, no ads, no trackers. The apps and the encryption code are published for review, and there is no ad, tracker or analytics of what you write anywhere in the app.

Harbor Fax's answer

I spent about 20 years in healthcare operations, and fax is still everywhere in that world. I watched patients struggle to get forms to offices, and saw how much private information passed through fax services that held onto it. Harbor Fax is part of Harbor Privacy, a small suite of privacy-first tools I started building in 2026. The idea was simple: send the fax, delete the file, keep nothing.

PrivacyNotes's answer:

PrivacyNotes started from a simple frustration: staying organized meant spreading your life across half a dozen apps, each with its own monthly bill. We wanted one place for notes, tasks, a journal, files and passwords, encrypted on your device, and paid for once instead of forever. So we built the encryption first, made it the base of every feature, and published the apps as open source so the promise can be checked, not just believed. Everything else grew from one rule: your data is yours.

Harbor Fax's answer

Individual consumers sending medical, insurance, and legal documents

PrivacyNotes's answer:

We do not keep a customer list to show, and that is on purpose. You can sign up with only a 12-word phrase, with no email and no name, and the app has no trackers and no analytics. So we do not profile the people who use it. A privacy product that watched its users closely enough to name them would miss its own point.
