Why your task app shouldn't need an account
Most to-do apps ask you to sign up before you can write a single task. Here's the case for local-first, and how Trayzero keeps every task on your device.
Published · 2 min read
Open almost any task manager and the first screen asks for an email. Before you've captured a single thought, your data has a home on someone else's server. We took the opposite default: Trayzero has no account, no server, and no cloud. You open the app and start.
What "local-first" actually means here
Every task, project, and note you create lives in a local SQLite database inside the app's private storage on your phone. There is no Trayzero backend for it to sync to — because there is no Trayzero backend at all. Your backup is a plain JSON file that you export and keep yourself.
That has three consequences worth being explicit about:
- No sign-up. Nothing to verify, no password to forget, no "continue with Google" that quietly links your tasks to an ad profile.
- No tracking. There are zero analytics SDKs in the app. Crash reporting is opt-in and off by default — you turn it on, or it never runs.
- It works offline, always. A plane, a tunnel, a dead Wi-Fi router: none of it touches your ability to capture and process. The app was never reaching out in the first place.
The trade-off, stated honestly
Local-first isn't free of cost — it just moves the cost somewhere we think is healthier. There's no magic "log in on a new phone and everything's there." You move your data with a backup file you control. We think owning that file beats renting access to your own tasks, but it's a real difference and you should know it going in.
It also means we can't see how you use the app. No funnels, no heatmaps. We read store reviews and reply to feedback instead. Slower, coarser — and the price of not watching you.
Why this fits Getting Things Done specifically
GTD asks you to trust your system enough to get everything out of your head and into it. That trust is easier to give a system that can't lose your data to an account lockout, a discontinued sync service, or a subscription you forgot to renew. A tray you fully own is a tray you'll actually empty.
If that's the kind of task app you've been looking for, Trayzero is free on Google Play and the App Store.

Local-First vs. Cloud-Based Productivity Apps: A Data Sovereignty Comparison
Local-first productivity apps store data on your device in formats like SQLite, giving you full ownership and offline access. Cloud-based task managers centralize data on vendor servers, enabling real-time collaboration but creating dependency. The core trade-off is data sovereignty versus collaborative convenience. Local-first apps like Trayzero, Obsidian, and Things 3 respond instantly and often use one-time purchase models, while cloud services like Todoist rely on subscriptions and network connectivity.
