Lockday

about

description

Lockday is a private planner for tasks, calendar and habits: post-quantum encrypted, offline-first, with a decoy PIN, no tracking and no Google services. ## Features - **Views and lenses.** See your tasks as a list, a Kanban board or a calendar, and plan your day hour by hour in the Planner. **Lenses** (beta) collect tasks from several projects into one saved view. - **Phones, tablets and foldables.** - **Recurring tasks.** Repeat daily, weekly, monthly, yearly, or on the second Tuesday of every month. Or aim for 3 times a week on any days you like. - **Tasks, events and time blocks.** Check off what you finish and place the rest on your calendar. - **Projects, sections and labels**, with priorities, deadlines, durations and subtasks. - **Templates.** Save a list of tasks as a template and add it all again in one tap. - **Home screen widget.** Add, edit, complete and delete tasks right from your home screen. - **Search and bulk actions.** Reschedule, move, label, complete and more on many tasks at once. - **Works offline.** Work on a flight, in the subway or with weak signal. Everything syncs when you're back online. - **Habit tracking** with streaks, heatmaps and history. (Pro) - **File attachments:** 10 GB of encrypted storage, files up to 100 MB. (Pro) ## Encryption Your data is encrypted on your device with AES-256-GCM. Keys are protected with a post-quantum hybrid of X25519 and ML-KEM-768. Our server stores your data but cannot read it. It sees only what it needs to sync and run your account: random IDs, timestamps, which item is in which project, your username and your Pro status. - **Decoy PIN and panic PIN.** A decoy PIN opens a normal-looking workspace, while your real tasks stay hidden and encrypted. A panic PIN also deletes your real data from the device. - **Biometric or PIN lock** with auto-lock. - **Shared projects.** Collaborators get the key only to that project and see nothing else. (Pro to share, free to join) - **No account required** to use Lockday on a single device. - **No email or phone number to sign up.** - **Sign in with a passkey.** You can create an account with no password at all. - **Two-factor authentication.** Sign in with two of your password, a passkey or a code from an authenticator app. ## This build has no Google code No Play Services, no Firebase, no Play Billing. Notifications arrive through Lockday's own push server with nothing extra to install. The same signed APK is on [lockday.net/download](https://lockday.net/download) with its SHA-256 next to it. ## Free forever. Pro for more power. Every privacy and security feature is free, including sync across devices. The free plan covers 5 projects and 10 labels with unlimited tasks. Pro lifts those limits and adds habit tracking, file attachments and project sharing, as a monthly or annual plan or a one-time lifetime purchase, paid by card or in Bitcoin on-chain. No ads, no trackers, no selling your data. How the encryption works in full: [lockday.net/security](https://lockday.net/security)
