How to keep your to-do list truly private

What makes a to-do list app actually private, and how Nydhei keeps your tasks encrypted end-to-end, tracker-free, and yours alone.

Your to-do list is one of the most personal documents you own. It holds health appointments, money worries, gift plans, job applications: a running transcript of your life. Yet most task apps treat that record as data to mine, synced in plaintext, scanned for “insights,” and monetized with trackers.

A private to-do list app should meet a higher bar. Here’s what to look for, and how Nydhei is built to clear it.

What “private” should actually mean

End-to-end encryption, on by default. Your tasks should be locked on your device before they sync, so the company running the servers cannot read them. That’s different from “encryption in transit,” which only protects the pipe.
No tracking or ads. If the app is free and ad-supported, your task titles are the product.
No forced account. Privacy starts with not having to identify yourself at all.
A clear, published list of what is and isn’t encrypted. Vague “bank-level security” claims are a red flag.

How Nydhei keeps your list private

Nydhei is private by default, not as a paid add-on or a buried setting.

Everything you write is end-to-end encrypted: task titles, descriptions, subtasks, note content, list items, even category and tag names. Only your devices hold the keys. See exactly what’s covered in End-to-end encryption.
No account required. Open the app and start planning. Your work stays on your device. Signing in is optional and exists only to enable encrypted sync. Start here: Welcome to Nydhei.
You hold the recovery key. Sync across devices is protected by a recovery phrase that only you know. Nydhei can’t read your data and can’t reset your key.

Try it in two minutes

Install Nydhei and choose Continue without signing in: no email, no name.
Create your first task (here’s how).
When you’re ready to sync a second device, sign in and link the device. Encryption travels with you.

Your plans stay yours. That’s the whole point.
