SealNote Privacy Policy

Effective date: 12 November 2026

SealNote is a notes app for iPhone, iPad and Mac. This page says what happens to your data when you use it.

In short

Your notes are encrypted on your device before they are written to disk or sent to iCloud.
They are stored on your devices and in your own iCloud. SealNote has no server of its own.
The developer does not collect, receive or sell any data about you, and cannot read your notes.
The app contains no ads, no analytics, no tracking and no third-party code that sends data anywhere.

What the app stores, and where

Notes, notebooks, tags and attachments. Everything you write or attach is encrypted on the device with AES-256-GCM. The encrypted files are kept on your device and, if you use sync, in the private part of your iCloud account, through Apple's CloudKit service. Text that the app recognises in your pictures and PDFs for search is produced on the device and stored encrypted together with the attachment.

Encryption keys. The key that opens your notes is created on your device and kept in your iCloud Keychain, which Apple encrypts end to end. You can also write down a recovery key. Neither is ever sent to the developer. If you lose both the keychain and the recovery key, nobody can restore your notes — the developer included.

Sign in with Apple. The app uses Sign in with Apple to know which person is using it. The identifier Apple gives the app, and your name and e-mail address if you choose to share them, are stored only on your device, to show which account is signed in. They are not sent to the developer.

Shared notebooks. When you share a notebook, its encrypted contents are placed in a shared part of your iCloud that the people you invite can open. Invitations are sent and accepted through Apple's sharing screens. The notebook has an encryption key of its own, which is passed to each participant encrypted for that person. So that others can do this for you, the app publishes a public encryption key in the app's iCloud database. That record holds a public key and an anonymous iCloud identifier; it contains no name, no e-mail address and nothing from your notes.

Camera, microphone and Face ID. The camera and microphone are used only when you take a photo or record a video for a note; the result goes straight into the encrypted note and is not saved to your photo library. Face ID or Touch ID is used to unlock the app; the app never sees your biometric data.

What the developer collects

Nothing. The app does not send usage statistics, crash reports, identifiers or content to the developer or to anyone else. Apple may give the developer anonymous, aggregated figures such as download counts and crash totals if you have agreed to share them with developers in your device settings; they do not identify you and contain nothing from your notes.

Apple's services

Sync, sharing, sign-in and the keychain are provided by Apple and are covered by Apple's own privacy policy: https://www.apple.com/legal/privacy/. Data in iCloud is stored by Apple in encrypted form; because SealNote encrypts notes before they leave your device, what Apple stores for the app is unreadable without your key.

Deleting your data

You can delete any note, notebook or attachment in the app; items in the trash can be removed permanently. Settings has a command that deletes all of your SealNote data — from the device and from your iCloud. Deleting the app from a device removes the data on that device only. You can also remove the app's data in your iCloud storage settings.

Children

The app is not directed at children and collects no data from anyone.

Changes

If this policy changes, the new version will be published on this page with a new effective date.
