Encrypted by design
Your vault is encrypted on the device. Security keys stay inside the application core.

01 · THE FOUNDATION
A place to think.
Not to worry.
Everything TextSandbox does starts with one principle: your data is not the product.
Offline first
Write, search and organize without an account or an internet connection.
Optional Cloud Sync
Sync encrypted data across devices only when you choose to enable it.
Version history
Review revisions, restore earlier work and keep your writing safe from mistakes.
Recovery by design
A one-time Recovery Key gives you a safe path back when a password is forgotten.
Built for text
Tabs, Markdown preview, search, attachments and a calm editor for daily work.
02 · YOUR DEVICES, YOUR FLOW
Sync on
your terms.
New device? Sign in, verify with your Master Password and restore an encrypted vault. No plaintext. No compromise.
