NASmeister is an iOS app that lets you monitor and manage your own Synology NAS. This policy explains what data the app handles. NASmeister is not affiliated with Synology Inc.
When you add a server, its profile — display name, address (IP / hostname / QuickConnect ID), username, optional note and image — is stored locally on your device. Your password is stored only in the iOS Keychain. This information never leaves your device except to sign in to the NAS you specified.
The app communicates directly with the NAS at the address you provide (on your local network, via your own remote access, or via Synology QuickConnect). Your credentials and requests are sent only to that NAS. We do not receive, proxy or store this traffic.
If you turn on notifications for a NAS (DSM 7.2 or later), the app registers this device with our notification service at push.nasmeister.app and adds a webhook and a notification rule named “NASmeister” in DSM. When DSM reports an event, it sends the event message to that service, which forwards it to your device.
The service stores:
It does not store your NAS’s name, address, credentials or any content from your NAS. The app shows your NAS’s name in a notification from data on your device. The web server keeps an access log with the IP address of each request for up to 14 days, for security; the webhook token is removed from it.
Notifications are delivered through Google Firebase Cloud Messaging and Apple Push Notification service. The service runs on Oracle Cloud Infrastructure in Frankfurt, Germany, behind Cloudflare.
Turning notifications off for a NAS removes this device from it; when no device follows a NAS any more, its record, token and events are deleted, and the app removes the webhook and the rule from DSM. A device that follows no NAS is deleted after 30 days.
If you choose to back up your server list to iCloud, only server metadata (names, addresses, usernames, notes and dashboard layout) is stored in your personal iCloud key-value storage, managed by Apple. Passwords and images are not included. This backup lives in your Apple account; we have no access to it. You can delete it from within the app at any time.
To improve stability, the app may use Google Firebase (Crashlytics and Remote Config). If active, this collects crash diagnostics and basic technical information (such as app version, device model, operating system version and coarse locale). It does not include your NAS content, credentials or the contents of your server list. This data is used only to diagnose crashes and to configure app features.
Deleting a server in the app removes its stored data and its Keychain password. Deleting the app removes all local data. Notification data on our service is deleted as described under Push notifications. An iCloud backup, if created, can be deleted from within the app.
NASmeister is a utility app not directed to children.
