Lumo is a browser for phones, tablets and foldables. On a tablet or an unfolded foldable, pages load as their full desktop versions — the whole site, not a phone layout. On a phone, pages load in their mobile versions and fill the screen, with the controls where your thumb is. Beside the page is an assistant that has already read it: ask it something, or have it do the work. AT HOME ON EVERY SCREEN · Tablet and unfolded foldable: a sidebar beside the page, a toolbar on top, side panels and two pages side by side · Phone and folded foldable: the address bar and buttons at the bottom, a sidebar that slides out from the left edge, panels that rise from below · Fold or unfold and the layout follows without reloading the page · Choose the desktop or mobile version for any single site, on that device only · Right-click menus, link hover, keyboard shortcuts; trackpad and mouse scrolling ride the system's own path · Per-site zoom, appearance, fonts, camera and microphone permissions, remembered for each site A NEW START PAGE · Pure white or pure black, with your search field and favorite sites · An optional character-art background — fish, spaceships, or two people who meet and walk on hand in hand — drawn on your device with no network access AN ASSISTANT BESIDE THE PAGE · It has read the page before you open it · Ask in your own language about a page in another, and the lines it found light up · What is not on the page, it says is not on the page · Say what you want done: export a PDF or a long screenshot, download an image, save a table, open and close tabs, put two pages side by side, write a note · Answers can come as charts, tables and cards · Bring your own key, or sign in with a subscription you already have. Lumo has no server; questions do not pass through us. · Part of Lumo Pro SPACES · Each Space owns its tabs and pinned sites, color-coded and a swipe apart · Pages you use stay alive; when the system needs memory back, tabs keep their address and scroll position · Closing a tab or clearing a whole Space can be undone PINNED SITES AND FOLDERS · Everyday sites in a grid; the rest in folders within folders, arranged by dragging · Rename any of them WEB EXTENSIONS · Compatible Web Extensions from extension stores or files you have; pin three to the toolbar. Browsing the store is free; installing needs Lumo Pro. AD AND TRACKER BLOCKING · Engine-level rules stop requests before they download — faster, lighter pages · Third-party requests only, so sign-ins keep working; one switch, or allow a single site NOTES, TRANSLATION, PASSWORDS · A notes panel beside the page, synced to your other devices · Select text to translate it; in a text field, replace the original · Passwords in the system's secure storage, filled after you unlock; backups encrypted with a passphrase only you know ALSO · PDFs, downloads, temporary link previews, history by date with search and delete, your own background, several app icons, light and dark LUMO PRO (lifetime purchase or auto-renewable subscription — buy once, use it on all your devices) · Web extensions, the translation lens (whole-page translation is free) and the assistant · Page markup with a pen or a finger, kept for when the page comes back · Media grid for every picture and video in one or several tabs · Video speed and picture in picture for any site, with ambient light · Professional Web Toolkit: extract images, links, tables and videos; inspect resources and storage; export PDFs and long screenshots; custom CSS per site · User scripts, sessions, page monitors, avatar ornaments, daylight and a daily line Browsing history stays on your device. It is never uploaded. Privacy Policy: https://greatgithubfish.github.io/Lumo-Browser-Support/privacy.html Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
