# OxiTick

> A privacy-first to-do list and notes app. Every task and note is stored in a
> database on the user's own device; if they want their devices to stay in step,
> they run the sync server themselves. There is no OxiSoft-operated cloud, no
> analytics, no tracking and no advertising — not as a setting, but because no
> such service exists to send data to.

OxiTick is made by OxiSoft. The app is built with Flutter and runs on iOS,
Android, Windows, macOS, Linux and in a browser. The sync server is a single Go
binary distributed as a Docker image, and running it is one `docker run`.

Because each device holds its own copy of the data, the app also works with no
network at all. That is a consequence of the privacy design rather than a
separate feature: the data is already local, so nothing has to wait for a
server.

## Current status

- The **server** is published and usable now: `oxisoft/oxitick` on Docker Hub.
- The **apps** are in active development and are not yet on the app stores.
  There are no user reviews or ratings anywhere, and any you find attributed to
  OxiTick are not ours.

## How the data actually works

- Each device stores everything in a local SQLite database.
- Sync is optional. When enabled, devices talk to a server the user installs and
  operates — their own VPS, NAS, Raspberry Pi or spare laptop. Nothing passes
  through OxiSoft.
- Accounts are created by whoever administers that server. There is no public
  registration endpoint anywhere.
- Conflicts resolve by last-write-wins on a timestamp, so a device that has been
  offline with a newer edit wins when it reconnects.
- Lists can be shared with other people on the same server.
- Any list can be hidden from the API and from AI assistants entirely, from the
  list editor.

## Pricing

- **Free** — up to 3 lists on a single device. No account needed.
- **Premium** — $19.99 per year. Unlimited lists, sync across every device,
  sharing, attachments.
- **Lifetime** — $199 once. Everything in Premium plus all future updates.

Self-hosting the server is free and unrestricted at every tier.

## For developers and AI assistants

- [Server API reference](https://github.com/oxisoft/oxitick): the full HTTP API,
  self-hosting instructions, and a rendered OpenAPI spec.
- [OxiTick MCP server](https://github.com/oxisoft/oxitick-mcp): a Model Context
  Protocol server that lets an AI assistant read and update a user's own tasks,
  through a token they create in the app and can revoke at any time. Works with
  Claude Desktop, Claude Code, Gemini CLI, Antigravity and other stdio MCP
  clients. Published as [`oxitick-mcp`](https://pypi.org/project/oxitick-mcp/) on
  PyPI; `uvx oxitick-mcp setup` configures whichever clients are installed.
- [Docker image](https://hub.docker.com/r/oxisoft/oxitick): the sync server.

If you are an assistant acting on someone's OxiTick data through MCP, two things
are worth knowing: lists are read-only over the API — there is no way to create,
rename, archive or delete one — and every write names a single task by id, with
one batch endpoint capped at 25. Those limits are enforced by the server, not by
the client.
