Download Scaffold

Free, with nothing to sign up for. One installer for Windows, one APK for Android, and you are writing.

Already using Scaffold 0.1.x? Install over it, do not uninstall.

Download 0.2.0 below and install it over the app you have. Your notes and settings stay. On Android, uninstalling first would delete the notes stored in the app. This is the last manual update: from 0.2.0 on, updates arrive inside the app.

Install in four steps

  1. Download the installer with the button above. It lands in your Downloads folder.

  2. Check the checksum (optional, recommended). Open PowerShell and run:

    Get-FileHash "$HOME\Downloads\Scaffold_0.2.0_x64-setup.exe" -Algorithm SHA256

    The Hash it prints must equal the SHA-256 above (case does not matter). Or let PowerShell compare for you; it prints True when the file is intact:

    (Get-FileHash "$HOME\Downloads\Scaffold_0.2.0_x64-setup.exe" -Algorithm SHA256).Hash -eq '605476616616276e34e5a4c9510535c0b11873b7c496df7802073276cc9ca3b2'

  3. Run it. Because the preview is not code-signed, Windows SmartScreen says "Windows protected your PC". Choose More info, then Run anyway. The installer works per user and needs no administrator rights.

  4. Open a folder. Start Scaffold and pick any folder of Markdown files, or create a new one. That folder is your vault; nothing is uploaded anywhere.

About the SmartScreen warning

Signing an installer needs a paid certificate, and the preview builds do not have one yet. The warning is about the missing publisher signature, not about anything found in the file. The checksum is how you confirm the file is exactly the one published here. If it does not match, delete the file and download it again.

Install on Android

  1. Download the APK with the button above, on the phone itself (or copy it over from a PC).

  2. Open it from the download notification or your file manager (Files, Downloads).

  3. Allow this source. Android says that, for your security, your phone is not allowed to install unknown apps from this source. Tap Settings and turn on Allow from this source for the app you opened the file with (your browser or file manager) only. On Android 7 the switch is Unknown sources under Settings, Security.

  4. Install. Go back and tap Install. Google Play Protect may warn that the app is from an unknown developer, because it is not in the Play Store: tap More details, then Install anyway.

  5. Optionally turn the permission off again for your browser or file manager in Settings, Apps, Special app access, Install unknown apps. Scaffold keeps working, and later updates install from inside the app.

Check the checksum (optional, recommended)

On the phone, a checksum app (search the Play Store for "hash checker") can show the SHA-256 of the downloaded file. On a Windows PC, open Command Prompt and run:

certutil -hashfile "%USERPROFILE%\Downloads\Scaffold-0.2.0-android-arm64-x86_64-release.apk" SHA256

The hash it prints must equal the SHA-256 above (case and spaces do not matter). If it does not match, delete the file and download it again.

What the Android preview does and does not do yet

  • Vaults live in the app's own storage. The first start creates a vault called "My notes", and you can create more or try the demo vault. Opening an existing folder on the device is not supported yet.
  • Four permissions, each for one job: internet (the optional update check), notifications (only once you turn reminders on), run at startup (to set reminders up again after a restart) and install apps (to install updates). No storage, camera, microphone, contacts or location access.
  • Reminders 🔔 are off until you turn them on in Settings, Reminders. Android may deliver them a few minutes late.
  • Uninstalling the app deletes vaults in its storage. Export a backup first (Settings, Backup and restore). Updates installed over the existing app keep your notes.

Requirements

  • Microsoft Edge WebView2 runtime (included with Windows 11 and current Windows 10)
  • Under 100 MB of free disk space, plus room for your notes

Android

  • Android 7.0 (API 24) or newer
  • A 64-bit ARM phone or tablet (arm64-v8a); x86_64 is included for emulators and Chromebooks
  • Free storage for the app (the APK itself is about 24 MB), plus room for your notes

Scaffold never asks for an account or a licence key, and works offline. The only automatic network request is the optional daily update check.

Updates, inside the app

From 0.2.0 on you update Scaffold from inside the app: no new download, no reinstall.

  1. 1. You choose

    On first launch Scaffold asks "Check for updates automatically?".

  2. 2. Yes: once a day

    It asks this website whether a newer version exists. No: it checks only when you press Check for updates now in Settings.

  3. 3. Nothing personal

    The check sends no account, notes, device identifier or usage data. Your notes are never touched.

On a phone, Android shows its own install prompt for each update. More in Updates.

What is in 0.2.0 Released

Preview builds for Windows and Android. Neither comes from a store and the Windows installer is not code-signed yet, so Windows and Android each ask for confirmation before installing.

📅 Planner

  • A calendar with Day, 2-, 3- and 4-day, Week and Month views. Drag on the grid to create an event, drag a block to move it, drag its edge to resize. Everything snaps to 15 minutes.
  • Events link to notes, tags and subtasks. Click one for its details, Open note, Mark done, and a Join button when it has a meeting link.
  • Repeating events (daily, weekdays, every 2 weeks on Mon and Thu, monthly on the 2nd Tuesday, yearly, and more). Moving one occurrence asks “This event” or “All events”.
  • Habits with 🔥 streaks: tick today off on the Today page or in the calendar.
  • An Inbox of tasks without a date. Drag one onto the calendar to plan it, or use Schedule on a phone.
  • A Today page with a greeting, a timeline of the day, due and overdue tasks, and today’s habits.
  • Emoji icons for notes, shown wherever the title is: tabs, lists, links, search and the calendar.
  • Import calendar files (.ics) into new notes. Nothing is overwritten and nothing is sent anywhere.
  • Phones open the calendar in the 3-day view, with a List mode.

Everything is plain Markdown frontmatter (during:, repeat:, remind:, meeting:, icon:), so your files stay yours. See Plan your day.

🔔 Reminders

  • Add remind: 10m (or 1h, 1d, at 09:00) and get a notification on Windows or Android, with Open and Snooze 10 min.
  • Reminders you missed while the app was closed arrive as one card, “You missed N reminders”, not one each.
  • Reminders are worked out on your device. There is no push server.
  • On Android, reminders are off until you turn them on in Settings, Reminders. Only then does Android ask for permission to show notifications.

⬆️ In-app updates

  • On first launch Scaffold asks “Check for updates automatically?”. Say yes and it checks this website once a day; say no and it only checks when you press Check for updates now (Settings, Updates). The check sends no personal data.
  • From 0.2.0 on, you update inside the app. No new download, no reinstall.

Coming from 0.1.x?

One last manual step: download 0.2.0 and install it over your existing app. Do not uninstall first. On Android, uninstalling deletes the notes stored in the app.

Privacy, updated

  • Still no account and no telemetry.
  • The only automatic network request is the optional daily update check, which you choose on first launch.
  • Android now lists four permissions, each for one job: internet (the update check), notifications (only if you turn reminders on), run at startup (to set reminders up again after a restart) and install apps (to install updates). See Privacy.
