Best private and local planner apps (2026)

What we looked for

Three questions decided the order: does your data live on your device by default, does it actually plan (a real calendar or weekly view, not just notes that can hold a task), and is the privacy story honest. The popular cloud planners are here too, clearly labelled, so you can see what convenience costs you.

The catch for the whole category: the most private apps are often the weakest planners, and the slickest planners are usually full cloud services. NotePlan comes closest to being both at once, and even it has caveats.

• Storage: does your data live on your device as the primary copy, ideally in a portable, readable format
• Planning: is there a real weekly or calendar surface, or is it a notes app you bend into a planner
• Honesty: open source and default encryption are bonuses; vague absolute claims ('no cloud', 'never leaves your device') are a red flag
• Longevity: can you export and leave, and does your data survive the app shutting down

NotePlan: the best genuinely-local actual planner (Apple only)

NotePlan is the rare app here that is both local and a proper calendar-driven planner. Each day is a plain Markdown note on your device, and it does real time-blocking, scheduled and recurring tasks, and forwards unfinished items. It two-way syncs with Apple Calendar and Reminders and supports Google Calendar. If you want plain-text ownership and a planner that plans, on Apple hardware, this is the pick.

• Pros: true daily and weekly planner with time-blocking; notes are plain Markdown files you own; sync runs through your own Apple iCloud, not NotePlan's servers; two-way Apple Calendar and Reminders sync
• Cons: Apple-only natively (Windows and Android get only the cloud web app, which undercuts the offline pitch); no app-level end-to-end encryption (it relies on iCloud, so enable Apple Advanced Data Protection if you want E2E); AI summaries and voice transcription send content to OpenAI when used; subscription-only and closed source
• Price: no permanent free tier; about $99.99/year (roughly $8.33/month) or about $12/month, with a 7-day trial
• Best for: Apple-ecosystem users who want a real calendar planner with Markdown ownership and are comfortable with iCloud sync

WeekToDo: the simplest free, fully-local weekly planner

WeekToDo is the only app on this list that is a purpose-built weekly planner and is fully local with no account at all. The core view is a seven-day layout of columns mixing a calendar concept with task lists. There is no server and no cloud component, so there is no central place your data can leak from. The trade-off is that the privacy comes from having no cloud, not from encryption, and that absence of a cloud also means no sync.

• Pros: genuine weekly planner with drag-and-drop between days, subtasks, recurring tasks, colour labels and reminders; completely free; open source (GPL-3.0); no account and no servers
• Cons: no cross-device sync (on the roadmap but not shipped), so your week lives on one device and you move it by manual export and import; no app-level encryption; no native mobile apps (mobile is via the website); it is list and column based, not an hourly time-blocking grid; development has slowed, with the last tagged desktop release in February 2024
• Price: completely free, no paid tier
• Best for: someone who wants a clean, free, single-device weekly planner and does not need sync

Super Productivity: the most defensible open-source local pick

If you want the cleanest 'truly local and open' story with real planning, Super Productivity is the strongest answer. It is MIT-licensed, works offline by default, needs no account, sends no telemetry, and is free with no paid tier. It combines a day and schedule planner, time-boxing, Pomodoro and built-in time tracking. Sync is optional and you control it: a local file, your own WebDAV (such as Nextcloud), or Dropbox, with optional user-key AES end-to-end encryption on the synced data so the provider only ever sees encrypted blobs.

• Pros: open source (MIT) and auditable; offline by default, no account, no telemetry; optional E2E encryption on sync where you hold the keys via your own WebDAV or local file; excellent for developers via Jira, GitHub and GitLab issue sync; free
• Cons: the local store itself is not app-encrypted (it relies on disk encryption), so losing your only device with no backup means losing the data; sync is hands-on to set up rather than seamless; the UI is utilitarian and can feel busy; mobile, especially iOS, is less mature than desktop; lighter on long-range calendar layouts than dedicated calendar planners
• Price: free and open source, no premium tier; an optional hosted encrypted sync service exists for people without their own WebDAV
• Best for: technically comfortable users, especially developers, who want a free, open, offline deep-work planner with no account

Logseq and Obsidian: powerful text-driven planning you assemble yourself

Both Logseq and Obsidian are genuinely local and private by default: no account required, no telemetry by default, and your notes sit on your machine as plain files. Neither is a turnkey drag-and-drop calendar. They are knowledge tools you build planning on top of, and both are excellent at text and task-driven weekly planning rather than visual time-blocking.

Logseq is the cleaner open-source story. It is fully open source (AGPL-3.0), and its automatic daily journals plus TODO, SCHEDULED and DEADLINE markers and built-in queries give you a basic weekly task and agenda workflow out of the box, more than vanilla Obsidian. The 2025 to 2026 caveat: the new SQLite 'DB version' is in beta with explicit data-loss warnings, and the DB and Markdown file formats are not interoperable. The stable file version still stores portable plain-text Markdown or Org files.

Obsidian is closed-source but far more polished, with a deeper plugin ecosystem. Its planning is a do-it-yourself assembly of free community plugins (Periodic Notes, Tasks, Calendar, Day Planner and Dataview) that becomes genuinely capable once configured, with a real learning curve and ongoing maintenance. The core app is free for all use including commercial work, with a commercial licence encouraged but optional.

• Logseq pros: fully open source and auditable; local plain-text files; better instant planning than vanilla Obsidian via journals and queries; optional official sync is end-to-end encrypted
• Logseq cons: smaller, slower-moving ecosystem and team; the DB-version rewrite is in beta with data-loss warnings and migration uncertainty; no native calendar grid or two-way external calendar sync; the strict outliner model does not suit everyone
• Obsidian pros: free including commercial use; extremely polished and extensible; the plugin-built planning stack rivals dedicated planners once set up; vault is portable plain text you fully own
• Obsidian cons: the core editor is closed source; planning is build-it-yourself, not native; no native at-rest vault encryption and no native two-way calendar sync; plugins are third-party code with broad vault access
• Price: both have a free, fully usable core. Logseq's official E2E sync is paid (and as of early 2026 still effectively in sponsor/beta access via Open Collective, with free Git, iCloud, Dropbox or Syncthing sync the practical default). Obsidian Sync is $4-5/month and Publish $8-10/month, both optional
• Best for: people who want a private, plain-text knowledge base with planning baked in (Logseq) or a polished, highly extensible vault they wire into a powerful planner (Obsidian)

Anytype: the strongest encryption story, a workspace you shape into a planner

Anytype has arguably the strongest privacy story of the local set: zero-knowledge end-to-end encryption by default, an encrypted local database on your device, and a sync layer (any-sync) you can self-host so nothing touches Anytype's servers. As a planner it is a private, Notion-style workspace rather than a turnkey daily planner. It has Calendar and Kanban views, Tasks as a type, tags and relations, so you can build a weekly board, but there is no time-blocking grid, reminders are weak, and it imports calendar events rather than syncing two-way.

• Pros: zero-knowledge end-to-end encryption on device and in sync; local-first storage; self-hostable sync node; flexible databases and views for knowledge work plus light planning; a real free tier
• Cons: not a dedicated planner (no time-blocking, weak reminders, calendar import only, weekly review is hand-built); the licence is source-available (Any Source Available License 1.0, non-commercial), not OSI open source; built-in AI is still in early prototyping and not shipped as of 2026; free network and backup storage is small (about 1GB) unless you self-host or pay
• Price: free tier at $0 with E2E encryption and unlimited local objects; paid plans are annual-only, $99/year (Builder) and $299/year (Co-Creator), roughly $8 to $25 per month equivalent
• Best for: privacy-maximalist users who want one encrypted, local workspace for notes, databases and light planning, and are happy to build their own calendar and weekly-review setup

Org-mode and TaskPaper: the power tool and the minimalist (both very local)

Two more belong here for the right person. Org-mode in Emacs is the most powerful fully-local planning engine of the lot: TODO state machines, SCHEDULED and DEADLINE timestamps, a powerful Agenda view that aggregates across files, repeaters and clocking, all in plain .org files you own. Privacy is essentially perfect because nothing leaves your machine. The cost is usability: it is Emacs-bound with a steep learning curve, no first-party mobile, and sync and encryption are do-it-yourself.

TaskPaper is the opposite end: a one-time-purchase Mac plain-text outliner where your tasks live in a single human-readable file you control. It is maximally private and future-proof, but it is light as a planner (no calendar, no time-blocking, no reminders engine) and Mac-only.

• Org-mode: free and open source (GPL); the deepest local agenda and scheduling engine here; plain .org files with optional GPG encryption. Gated behind Emacs; not approachable for non-technical users
• TaskPaper: about $24.99 one-time, no subscription; a single plain-text file you own outright; dead simple and portable. Too light for full weekly planning; macOS only with no first-party mobile or sync
• Best for: Org-mode suits technical users who want the most powerful vendor-free agenda; TaskPaper suits Mac users who want a future-proof local to-do outliner they buy once

Notes apps that can hold tasks: Joplin and Notesnook

These two come up constantly on privacy lists, and they are excellent privacy notes apps, but be clear-eyed: neither is a planner. They have task and checklist notes, due dates and reminders, but no native weekly-calendar or time-blocking view. You can run a weekly note, but you are improvising a planner, not using one.

Joplin is offline-first and open source (AGPL), storing Markdown in a local database. Its critical nuance: end-to-end encryption is opt-in, not on by default, so if you sync via Dropbox or OneDrive without enabling it, the provider can see your notes. Sync itself is optional and you choose the backend (local folder, Nextcloud, WebDAV, S3, self-hosted, or paid Joplin Cloud). Notesnook is the encryption-forward one: zero-knowledge end-to-end encryption is always on and not optional, the clients are open source (GPL-3.0), and the sync server is self-hostable. Its free tier is genuinely usable with unlimited notes and devices, capped on storage.

• Joplin pros: offline-first, open source, flexible sync backends, free if you self-host or use Dropbox/Nextcloud/WebDAV. Cons: E2EE is off by default (trips up people who assume synced notes are private); not a planner without community plugins
• Joplin price: app is free; optional Joplin Cloud sync from about EUR 2.99/month (around EUR 2.40/month billed yearly) for 2GB, up to Pro tiers; all fees avoidable by self-hosting or using your own cloud drive
• Notesnook pros: always-on zero-knowledge end-to-end encryption (XChaCha20-Poly1305 with Argon2), open-source clients, self-hostable sync, a real free tier with unlimited notes and devices. Cons: no calendar or week view and no plugin ecosystem to add one; rich-text rather than plain Markdown, so less portable as raw files; free-tier storage caps are tight
• Notesnook price: free tier (with storage caps); paid Essential about $1.99/month, Pro about $6.99/month, Believer about $8.99/month (pricing was recently restructured, so ignore older sources quoting a single $4.99 Pro plan)
• Best for: people who want secure notes that can also hold to-dos, not a structured weekly planner

The popular cloud planners, named for contrast

These are capable and in some cases best-in-class planners, but they are cloud-only with no local-storage mode, so we list them only so you can see the trade. If your priority is keeping data on your machine, these are not the pick.

A middle group deserves a fairer note: Reflect and Amplenote are cloud apps but offer end-to-end encryption of note content, which puts them a step above plain cloud to-do apps. They still require an account and store data on their servers, so they are E2E cloud, not local.

• Todoist: cloud-only on AWS, AES-256 at rest, SOC 2, but no end-to-end encryption and no local mode. Strong task planner
• TickTick: cloud-only on AWS, vendor-managed encryption, no E2E, no local mode. Feature-rich (calendar, habits, Pomodoro)
• Sunsama: cloud-only guided-planning service that aggregates your other cloud accounts; best planning ritual, least local; no E2E
• Akiflow: cloud-only command-centre aggregator; no local mode and no end-to-end encryption (it does have native iOS and Android apps)
• Motion: cloud plus AI auto-scheduling; the most cloud and AI-dependent option; no local, no E2E
• Tana and Capacities: cloud-only by design with explicitly no local-only storage; Capacities is EU-hosted with server-side encryption; neither offers E2E
• Reflect and Amplenote: E2E-encrypted cloud (better than plain cloud), but still account-based and server-resident, not local

Where asambl fits (and where it does not)

Full disclosure: this guide lives on asambl's site, so here is the honest placement. asambl is a desktop Life OS for macOS and Windows, and your vault of notes and plans stays on your machine as local files (SQLite and Markdown) that you can export. In the storage sense it belongs with the local set.

But it is not a fully-offline tool, so it does not belong at the top of a 'local' list. Weekly planning in asambl uses a cloud call to its managed AI (hosted on Azure OpenAI). With AI switched off you get structured templates, not auto-drafted plans. Apps like Obsidian, Logseq, Super Productivity, WeekToDo and Org-mode are more local than asambl, because they need no cloud at all.

asambl's actual edge is different. It genuinely drafts your week (real planning automation) while keeping the vault on your machine. When AI is on, only the prompt for that one request goes to the managed endpoint and it is not stored long-term; semantic search and embeddings run on your device. There is no bring-your-own-key and no provider choice. If you want a polished desktop planner that does the drafting for you and keeps the vault local, and you are comfortable that planning uses a cloud AI you can switch off, asambl is worth a look. If you need a tool that works with no network at all, choose one of the fully-local picks above. asambl is free during its beta, which opens on 27 June 2026.
