About Lock Notes: Personal Diary
Keep a personal notebook for your thoughts, diary entries, ideas and everyday lists. Lock Notes gives your writing its own space, with a passcode and supported biometric unlock to control access.
WRITE THE WAY YOU THINK
Give long notes structure with headings, bold and italic text, lists and checklists. Add photos directly into your writing, keep a simple journal, or capture an idea before it slips away.
FIND WHAT MATTERS
Search your notes and find text inside an open note. Automatic saving keeps your edits as you write and when you leave the editor. A clean layout keeps the focus on your text.
TAKE YOUR WRITING WITH YOU
Export notes as TXT or formatted PDF, share the notes you choose, and print a copy. Use exports for a personal archive, a draft to continue elsewhere, or a list to share.
RECOVER AN ACCIDENTAL DELETION
Recently Deleted keeps removed notes for up to 30 days, so you can restore one before it is permanently deleted.
CHOOSE HOW YOU WORK
Write with local storage, adjust the appearance, and use a light or dark interface. Optional cloud synchronization is available with Premium and a compatible cloud account.
From a short memo to a longer personal journal, keep your writing easy to find and comfortable to read.
