Notes App

Keep multiple notes with titles, a searchable sidebar, auto-save to localStorage, Copy for the active note, and JSON export/import for backups — all in your browser like APK String Extractor keeping strings on-device. For checkbox tasks instead, use Todo List; for Markdown preview, see Markdown Previewer.

What this tool does

Notes App is a lightweight, offline-first scratchpad for anything that does not fit a checkbox list: meeting bullets, draft copy, snippets, or Markdown-style text you will paste into another app. Like APK Analyzer, nothing is sent to DroidXP — everything you type stays in localStorage on your device.

Privacy and storage

There is no account, no sync, and no server-side note storage. Data is scoped to this origin and your browser profile. If you need portability, use Export all to download JSON and store it wherever you trust — same backup mindset as downloading extracted strings from APK String Extractor.

Compared to Todo List

Todo List optimizes for tasks with done/active filters. Notes App optimizes for longer text, multiple documents, and a backup file workflow.

How to use the Notes App

  1. Step 1: Click New note — edit the title and body; changes save as you type.
  2. Step 2: Use Search to filter the sidebar; click a note to switch.
  3. Step 3: Copy note for a title + body block, or Export all / Import for backups.

Frequently Asked Questions

Does DroidXP upload my notes to a server?

No. Notes exist only in your browser — the same local-only stance as APK Analyzer and APK String Extractor. Content is stored in localStorage on your device unless storage is blocked or cleared.

Where are my notes stored exactly?

In your browser’s localStorage for this site origin (droidxp.com). Each browser profile has its own data. The tool does not add encryption beyond what the browser provides.

What happens if I clear site data or cookies?

localStorage for this origin is removed — your notes are gone unless you exported a JSON backup first. Use Export all regularly for anything you cannot lose.

Does private / incognito mode keep my notes?

Usually only for that session; closing the private window often wipes storage. Treat incognito as ephemeral and export before closing.

Can I sync notes across my phone and laptop?

Not from this page alone — there is no account or cloud sync. Use export/import to move a snapshot manually, or paste into your own sync service.

How is this different from the Todo List on DroidXP?

Todo List is checkbox tasks with filters. Notes App is for longer freeform writing, multiple named notes, search, and JSON backup.

Does this render Markdown?

The editor is plain text. You can write Markdown-style syntax for your own workflow and paste into a renderer elsewhere, or use a dedicated Markdown previewer on DroidXP.

Is there a size limit?

Browsers cap localStorage (often a few MB per origin). Very large notes or hundreds of notes may hit limits — export and archive old material.

Who can read my notes on this device?

Anyone with access to your unlocked profile can open DevTools or other pages on the same origin. Do not store secrets you would not keep in a plain local file.

What is in the JSON export?

A portable file with note ids, titles, bodies, and timestamps. Import merges by id — keep backups in a safe place outside the browser.
