Offlog
Your tasks. Your devices. Nobody else's.
Off the cloud, still logged.
A free, open-source, local-first task manager. No account, no telemetry,
no subscription, ever. Runs in the browser, as a native Android app, and
as a Windows desktop app — all three share the exact same codebase and
sync with each other over your own network.

Real captures of the Windows app — no mockups, no Lorem Ipsum. On a phone
the same data gets its own layout, with Home, Today, Agenda and Search tabs.
Why this exists
Every task manager I tried wanted a subscription for things that should
be free — a due date, a reminder, more than three projects. The ones that
didn't were overloaded instead, buried under features built for a growth
chart rather than for me. And all of them wanted my data on their
servers.
That last one has no workaround. A task list is a fairly complete map of
a person's life, and I didn't want mine living on a company's
infrastructure, one business-model change away from becoming their asset.
Offlog is the opposite of all three: the basics are free because
everything is free, the feature list stays small on purpose, and your
data never leaves the machines you own. Your phone and your PC talk to
each other directly over your own Wi-Fi — no cloud in the middle, no
account, nothing held back behind a paywall. It works fully offline
either way.
It's a personal tool, given away as-is. The same model works for a small
trusted group on one network — a family, a couple of people in one office
— but it is not a multi-tenant product: no per-user permissions, no
accounts, and sync only ever happens on your own local network.
What it does
Organizing
- Spaces hold projects; each project has its own statuses
- Board and List views per project, with saved filters and
multi-column sort
- Agenda — deadlines across every project, as a grouped list or a
month calendar
- Focus (the Focus tile on the phone's Home tab) — pick up to 3 tasks for today.
A deliberate commitment, not an auto-generated list nobody trusts
Tasks that hold real detail
- Notes, priority, due date, a reminder independent of it, checklists,
tags, your own fields, and file attachments up to 10 MB
- Dependencies — mark a task as blocked by another. Circular chains
are refused
- Recurring tasks reset in place instead of spawning duplicates, and
handle month-end and DST correctly
- Every change to a task is recorded, so you can see its History
Finding things
- Ctrl+K searches titles, notes, tags, checklist text and attachment
filenames — and tells you where it matched
- Ctrl+N adds a task from anywhere, parsing dates,
#tags,
!priority and @project out of what you type
Not losing things
- Soft delete with undo everywhere, plus a Recycle bin
- Backup and restore including attachments, fields and tag colors — a
restore brings back the workspace, not just the text
- Automatic local backups, last 7 kept
- A database check-and-repair tool for orphaned tasks and invalid states
- An optional App Lock: a PIN, fingerprint or face unlock on Android,
and a recovery code shown once, to copy or (on the phone) share. Lose both PIN and code and there is no way
in — there is no server to prove who you are to
Sync — the actual point
Most local-first apps stop at "sync works if you run your own server."
That's a real barrier for anyone who doesn't want to. Offlog's Windows
app is the server: it bundles
NyxDB — a small
CouchDB-protocol server written for this project — configures itself on
first launch, and your phone finds it automatically over the network.
Pairing is a six-digit code shown on the PC. No typed IP addresses,
no credentials sent before pairing, and if your PC's address changes the
phone re-finds it instead of making you pair again.
Synced tasks are end-to-end encrypted (AES-256-GCM). The key is made
by your PC and handed over inside the pairing, so there is nothing to
remember. The sync server stores only scrambled data. The Wi-Fi
connection itself is plain HTTP; a server you run yourself gets readable
data. Details in docs/security.md §3.
Everywhere else
- Light, dark, high contrast, and a reduce-motion setting every animation
actually respects
- Keyboard-operable throughout; WCAG AA contrast
- Android: a layout made for the phone, portrait and landscape; a
home-screen widget with Focus, Quick Add and Home buttons; notification
actions; hardware back button
- Windows: lives in the tray,
Ctrl+Alt+O from anywhere, native
notifications and save dialogs, automatic updates
Status
In daily use since 1 August 2026, and actively maintained.
The plan it was built to is complete — that was the goal, not a stopping
point. Bugs found in real use get fixed, dependencies get updated,
security reports get answered.
Every release runs a zero-warning build, a clean type check and
1325 tests through CI. It has been
through 30 structured
maintenance audits against a written checklist of blind spots earned
from real shipped bugs — what each one found.
What's next: the phone layout gets a final check on a real phone
before it is released, and the Play Store listing is waiting on Google's
review. Peer-to-peer sync between phones was
investigated and closed — Android blocks every route to it, and the
reasoning is written down in docs/decisions.md so it
does not get reopened on a hunch. Sync still runs through a self-hosted
host on your own network.
