Your personal diary, and nobody else’s. No account, no ads, and nothing leaves your phone unless you ask. Write about your day, add a photo, track your mood, and keep it all. PRIVATE, NOT MERELY ENCRYPTED • No account. Nothing to sign up for, nothing to sign in to. • No analytics, no trackers, no advertising inside the app. • Most diaries keep your writing on a server. This one has no server to keep it on. • A diary with a lock: Face ID, Touch ID or a passcode, with Scriptum Complete. WRITE IT YOUR WAY • A line or a thousand words, whatever the day needs. • Make it a photo diary: add a picture to remember the day by. • A simple mood tracker: tap one of five faces for how the day felt. • Note where you were, when that is part of it. • Missed a day? Open the calendar and write it whenever you like. • Light or dark paper, to suit the hour. • Stuck for words? A prompt is there if you want one. • A gentle reminder at the time you choose, which eases off instead of nagging when you have been away. ON YOUR HOME SCREEN • The widget shows the date and whether you have written today. • It never shows a word you wrote. That stays inside. FIND IT AGAIN YEARS LATER • Search everything you have ever written. • Every photo in your diary in one place, month by month, and every voice note too. • A calendar of the days you wrote, and the days you did not. • Open any date and read it exactly as you left it. AND STILL IMPOSSIBLE TO LOSE • A copy of your diary is kept in your own iCloud, so deleting the app does not take it with it. • Nothing is sent to us. The copy sits in your iCloud Drive, where you can see it. • Or save the whole diary, words and photographs, as one file only you hold. • Coming from Day One or Daylio? Bring your entries with you. ON IPHONE AND IPAD • On iPad your diary is laid out as a single sheet of paper, with room to write. • Each device keeps its own diary, and you can bring your iPhone’s pages across. SCRIPTUM COMPLETE An optional upgrade, for when the free diary is not enough. Try it free for a week. • Lock your diary behind Face ID, Touch ID or a passcode. • Speak instead of typing, and have a rambling entry tidied into something you will want to reread. • Keep voice notes on a page, and hear the day again in your own voice. • Up to ten photos on a page, arranged for you. • Every sticker pack, and ink to sketch over the paper. • Colour the whole app to suit you. • Turn your diary into a printable book, typeset page by page. Scriptum Complete is a monthly or yearly subscription. The yearly plan starts with a free week for new subscribers. Payment is charged to your Apple Account when the free week ends, or at purchase without one. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your Apple Account settings.
