📚 How Browser Storage Works
What is Browser Storage?
Browser storage is a mechanism that allows web browsers to save data on your computer. While traditional web applications store data on servers, browser storage enables saving your input content directly on your own computer. This online notepad utilizes browser storage to provide auto-save functionality.
localStorage vs sessionStorage
There are two main types of browser storage. This online notepad uses <strong>localStorage</strong>, which persists data even after closing the browser, whereas <strong>sessionStorage</strong> automatically deletes data when the browser tab is closed.
| Feature | localStorage | sessionStorage |
|---|---|---|
| Data Retention | Persists until browser clear | Deleted when tab closes |
| Cross-tab Sync | Shared within same domain | Independent per tab |
| Capacity | Typically 5-10MB (browser-dependent) | Typically 5-10MB (browser-dependent) |
| Use Cases | User settings, draft saving | Temporary session data |
Data Security
- Stored locally on your computer: Browser storage saves data on your computer, so there's no risk of data being intercepted over the internet. Content you enter in this online notepad is saved only on your computer.
- Delete by clearing cache: For enhanced security, you can reliably delete saved data by clearing cache and local storage from your browser settings.
- Private browsing behavior: Browser storage may be disabled in incognito or private browsing mode. We recommend regularly downloading important notes as files.
- Cross-device access: Browser storage is device-independent, so data is not synced between different computers or smartphones. If using the same browser (e.g., Chrome on multiple devices), some features may sync only if browser sync is enabled.
- Privacy protection without server transmission: This online notepad does not send user input to any server. Your privacy is maximally protected, and your note content is never seen by anyone.
Browser Storage Capacity and Limits
Most browsers allocate 5-10MB of storage per domain. This capacity is sufficient for text-based notes, but if you need to store very large amounts of text (tens of millions of characters), we recommend regularly downloading to manage capacity.
Security Measures Implemented in This Tool
- Client-side processing only: All processing runs in your browser, so data is never transmitted over the network.
- HTML escaping: Input text is properly escaped to protect against XSS (Cross-Site Scripting) attacks.
- HTTPS communication: ToolMarche is protected by HTTPS, so all communication between browser and server is encrypted.
❓ Frequently Asked Questions
Q: My notes are not being saved
A: Local storage may be disabled in your browser settings, or you may be using private browsing mode. Check your browser settings to enable local storage. We recommend regularly downloading important notes.
Q: I want to sync notes across multiple devices
A: Browser storage is device-independent, so syncing is not enabled by default. To share across devices, download the text and save it to cloud storage, or consider using a cloud-based note app.
Q: Where are my saved notes stored?
A: They are stored in browser local storage. The specific location varies by browser, but you can check it using the browser developer tools (F12 key).
Q: Will I lose my notes if I clear browser cache?
A: Yes, clearing browser cache will also clear local storage, and your saved notes will be lost. Always save important notes using the download feature.
