UpNote

This is a community package of UpNote, maintained independently and unaffiliated with UpNote Pte. Ltd. It repackages the official Linux Debian package.

One thing is added inside the app: a small preloaded library (LD_PRELOAD) that reports a fixed process ID to the tray code. Every Flatpak app runs as process 2 in its own sandbox, so without it the tray icon competes with other sandboxed apps for the same name and may not appear. The real process ID is still used wherever the system checks it, and nothing else is changed.

UpNote is a note app for long-form writing: notes live in notebooks that nest as deeply as you like, and the editor mixes rich text with Markdown shortcuts.

• Nested notebooks, tags, links between notes and full-text search.
• Rich text editing with Markdown input, code blocks, tables, attachments and math.
• Focus mode, themes and a light or dark appearance.
• Import from Evernote, Apple Notes, Bear and Simplenote; export to Markdown, HTML, PDF or text.
• Sign in to sync notes with the other UpNote apps. Sync and some editing features are part of UpNote Premium, a paid subscription from the developer.

Permissions: this package grants network access for sign-in and sync, display and GPU access, notifications and a tray icon. Your home directory is not visible to it — notes are kept in the app's own data directory under ~/.var/app/com.getupnote.UpNote, and import and export go through the file chooser portal, which hands the app one file or folder at a time.

If you would rather give it a directory of its own — to keep exports somewhere fixed, or to reach a folder of files you import from often — grant that one directory yourself:

flatpak override --user --filesystem=~/Notes com.getupnote.UpNote

Review or undo what you have granted with "flatpak override --user --show com.getupnote.UpNote" and "flatpak override --user --reset com.getupnote.UpNote".
