Notelock: Notes, To-Do & Diary

Notelock is a private notes and to-do app that keeps everything on your own phone, behind a PIN. Write notes, tick off tasks, get reminders — with no account, no sign-in and no cloud. Most notes apps ask you to hand your thoughts to a server. Notelock does not have one. Your notes, tasks and settings live in an encrypted database on this device, and the app works with no internet connection at all. WRITE ANYTHING - Plain notes or tick-box checklists, whichever the moment needs. - Headings, bold, italic, bullets and numbered lists. - Ready-made templates for meetings, journals and shopping lists. - Colour-code your notes and file them with tags. - Connect ideas: type [[a note title]] to link two notes, and see every note that links back. - Version history, so an earlier draft is never really gone. - Archive notes to clear your list without deleting, and a Trash that lets you undo a delete. STAY ON TOP OF YOUR DAY - Add a task in plain English — type "Call the dentist tomorrow 5pm urgent" and the date and priority are filled in for you. - Due dates, priorities, sub-tasks and repeating tasks. - Put a reminder on any note or task and get a notification when it matters. - A daily digest that tells you what is coming up. - A focus timer for getting one thing finished. - A Today screen for what is due, overdue and recently edited. - A month calendar of your notes, tasks and reminders. - Search every note, task and tag at once. - An insights screen showing your writing and task-completion streaks. LOCKED, NOT JUST HIDDEN - A PIN opens the app. Fingerprint and face unlock are optional. - The app can re-lock the instant you switch away from it. - Lock a single sensitive note so it stays hidden even inside the app. - Note content is blurred in the app switcher, and screenshots can be blocked. - Reminders can be set to reveal nothing on your lock screen. - Everything is stored with AES-256 encryption on the device. - No ads, no analytics, no tracking, no data collection. YOUR DATA, YOUR MOVE - Export every note and task to one password-protected file, and import it to restore or move to a new phone. - Because there is no cloud sync, that export is the only way your data leaves the device — and only when you choose to make it. TOOLS THAT DO THE BORING PART - Working offline with no account needed: summarise a note, suggest a title, suggest tags, pull out action items, find dates and turn them into reminders, tidy up spacing and capitalisation, turn text into a bullet list or a checklist, and show word count and reading time. - An assistant screen where you can search your notes and create notes, tasks and reminders just by typing what you want. - Optional cloud writing tools are turned off by default. They work only if you paste in your own API key from a third-party AI service you have signed up for and pay for separately. Notelock does not provide, include or sell a key, and nothing leaves your device unless you add one and use those specific tools. BUILT FOR EVERYONE - Full screen reader support, adjustable text size, light and dark themes. No trial, no subscription, no in-app purchases. Every feature above is included.
