Quillday is not a Quillday.com membership. There is no Quillday account and no public feed. Your pages, photos, and optional audio live on this iPhone, iPad, and Apple Watch — with an encrypted copy in your own iCloud that Land Tech cannot open. What makes Quillday different • Time Capsule letters you seal until a date you choose (the notice never quotes the letter) • A real Apple Watch companion: speak or type a short page, mood check-in, optional Health snapshot after you save — pages land in the free journal on iPhone • Encrypted backup in your iCloud Documents, sealed with a key only your Apple ID holds • Quillday Plus can merge iPhone and Mac through your CloudKit vault — if both devices edited the same page offline, Quillday keeps both versions as a Conflicted copy instead of overwriting • Ask your journal and Companion stay on this device by default; an optional key you paste only sends excerpts after you confirm Send • Import history from other journal apps, then keep writing here Write today • Pages with headings, lists, and emphasis, plus a title, date, and time • Photos from the camera or library, including photos from this day after you tap that action • Tags, favorites, pins, search, and a calendar • Optional place and weather when you add them • Passcode and Face ID or Touch ID lock • Daily writing reminder if you turn it on • Export as text (.txt or .md), PDF, JSON, or CSV • Passphrase-encrypted .qday archive you can share or restore • Merge two journals into one, or move a page to another journal Free on this device One journal with photos, tags, search, calendar, lock, local export, a daily prompt, a writing streak, and On This Day (including an optional morning notice).

Quillday Plus (optional yearly subscription) • Unlimited journals • Audio and video attachments • Templates and the full prompt library • Encrypted cloud sync and merge across your Apple devices • Writing insights and year in review • Mood charts from your local check-ins • Private companion and Ask with a key you paste (on device by default) • Life stories and Time Capsule letters • Print a book from a journal • Extra widgets and Watch complications beyond the free write-today tile Payment is charged to your Apple ID.

Quillday also keeps one encrypted copy in your own iCloud so a reinstall brings your pages back — sealed with a key only your Apple ID holds, which we never receive. Weather uses Open-Meteo only after you add a place. An optional model key you paste may send a short pack of recent notes, or Ask matching excerpts, to the AI provider you choose — only after you confirm Send in the app. Land Tech does not host your diary and cannot recover a lost passphrase. A native Mac client is a separate Mac App Store binary and is not this iPhone download.
