About Data Protocol and TackNote.app

In their own words, as submitted to SaaSHub.

Data Protocol
TackNote.app

No description of Data Protocol yet.

TackNote is a Mac sticky-note app with a twist: every note pins to the exact thing you're working in — a specific window, browser tab, document, folder, chat, or task — and only appears when you're there. Switch away and it tucks out of sight; come back and it's waiting, right where you left it....

Questions & Answers

As answered by people managing Data Protocol and TackNote.app.

Which are the primary technologies used for building your product?

TackNote.app's answer:

A native macOS app built in Swift and AppKit, with CloudKit for optional end-to-end-encrypted iCloud sync. No web wrappers, no third-party trackers

What makes your product unique?

TackNote.app's answer:

Most sticky notes just pile up on your desktop. TackNote pins each note to the exact thing you're working in — a window, browser tab, document, folder, chat, or task — and shows it only when you're there. Switch away and it tucks out of sight; come back and it's waiting. The right note, in the right place, automatically.

Why should a person choose your product over its competitors?

TackNote.app's answer:

Context-aware — notes follow your windows, tabs, and docs instead of cluttering the desktop - Private by design — end-to-end encrypted, notarized by Apple, no account required - Fair pricing — 14-day free trial (no card), then a one-time $24.99, no subscription - Native Mac app — fast and light, not an Electron wrapper - Plus checklists, voice notes, reminders, projects, and 12 themes.

How would you describe the primary audience of your product?

TackNote.app's answer:

Mac users who juggle multiple projects, research, or workflows and want quick reference notes tied to context — developers, writers, researchers, students, and anyone tired of a desktop buried in stale stickies or one endless note list.

What's the story behind your product?

TackNote.app's answer:

Early one morning I needed to remind myself to push a sandbox site to production, but not at peak traffic, so it had to wait. I had nowhere clean to put the reminder. My only option was a floating sticky note that would get buried under all my open windows the second I started working.

Then it hit me: what if I could tack the note to the push window itself? So, the next time I opened it, the reminder would be right there waiting!

That's TackNote. Every note pins to the exact window, tab, or document it's about, and shows up only when you're there.
