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.
• Posts — Write a post and share it with a short link that lasts as long as you choose, up to a month. Each post stays a file in your own storage.
• Huddle — Chat with others directly, device to device: invite them with a link, and nothing passes through a server.
• 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.
• Files — Your files on this device, in clouds and on servers: browse, share, archive and encrypt them, plus PDF and metadata tools.
• Books — Read e-books, PDFs and comics your way, with highlights and notes, and pick up where you stopped on any device.
• 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.
• Footprint — See what websites and apps can learn about your device.
• Sensor Lab — Your phone as measuring instruments: level, sound meter, tuner, compass, speedometer, heart rate and more, with live graphs and recordings.
