Privacy Policy

Dunlin is a local-first to-do app. Your tasks live on your device. We collect as little as possible and never sell your data or use third-party advertising or analytics trackers. Last updated 15 June 2026.

What we store, and where

Everything you create — projects, steps, recurring upkeep, and your settings — is stored on your device. If you don't sign in, none of it leaves your phone.

Optional account & sync

Signing in (with Sign in with Apple) is optional. If you do, your tasks are synced to your private cloud record so they're backed up and available on your other devices. Sync is stored with Google Firebase (Firestore) and is readable only by your account. We store your account identifier and, if Apple provides it, your name and email — used only to run your account.

AI features

When you use “Organise this” or “Break it down”, the text you provide (your brain-dump, or a project's title and notes) is sent to our server and on to Anthropic's Claude API to generate suggestions, then returned to you. It is processed only to produce that result and is not used to train models. If you don't use these features, no task text is sent anywhere.

Microphone & speech

Voice capture is opt-in and only runs while you hold the mic. It uses Apple's Speech Recognition to turn your speech into text; per Apple, that audio may be processed on your device or by Apple. We don't record, store, or transmit your audio ourselves — we only receive the resulting text, which you then choose to keep.

What we don't do

No advertising, no third-party analytics or tracking SDKs, no selling or sharing of your data, no location tracking.

Deleting your data

You're in control. Delete any item in the app (with undo). To remove your cloud account and synced data entirely, use Account → Delete account — this permanently deletes your cloud record and account. Data stored locally on your device is removed by deleting the app.
