Private tools. Your data stays yours.

Notes, a password vault, invoices, QR and barcode tools, and a browser footprint viewer. No server, no tracking: everything is stored in your own cloud storage.

Tools

• Notes — Quick notes and a knowledge base in one place, organised in folders and saved as plain Markdown files.
• Vault — Passwords, two-factor codes and identity documents, encrypted on your device with a master password or passkey.
• Invoices — Issue invoices as PDF or DOCX, e-mail them and keep the whole registry yourself.
• Codes — Make and read QR codes and barcodes in every common format, offline.
• Dev Tools — JSON, JWT, Base64, hashes, timestamps, regex and more developer utilities, all offline.
• Assistant — A private AI chat that runs on your own device: the model is downloaded once and nothing you type leaves it.
• Digital Footprint — See what your browser tells every website you visit.
