Privacy

What the app knows about you.

Last updated 18 August 2026 · applies to DynDnsPulse 1.2.0 for macOS, iOS and iPadOS

Who is responsible

The controller for this website and for the app, in the sense of the GDPR, is:
Thomas Pallus, Talstraße 25a, 51399 Burscheid, Germany
Email: info@business.pallus.io
Full provider identification: legal notice

What is stored, and where

Your provider credentials, meaning API tokens, keys and passwords, are stored in the system keychain on the device. The rest of your setup, meaning which providers are enabled, the hostnames and the check interval, is stored in a configuration file inside the app's own container on the device.

The update history is stored on the device as well. It is there so you can see what happened and when.

What leaves the device, and to whom

• To an IP lookup service: a request that returns your current public IP address. The service can see that address and the fact that a request was made, as it can for any visit from your connection.
• To the DNS providers you configured: the update request itself. That means your hostname, the new IP address, and the credentials that provider requires. This goes to the provider you chose, over HTTPS, and it is the whole purpose of the app.

Those are the only outbound connections the app makes for its own work. There is no server belonging to the developer in the path.

What is not collected

• No account, no sign-in, no email address.
• No analytics, no usage statistics, no crash reporting service.
• No advertising identifiers, no third-party trackers.
• No cloud sync of your configuration or your credentials.

Exported configuration files

Since version 1.2.0 you can export your setup to a file. Including credentials in that file is optional. When you do include them, they are encrypted with a passphrase you choose, using AES-GCM, and the app never writes an API token to a file in plain text. Without that passphrase the file cannot be restored, and the passphrase cannot be reset.

Once an exported file leaves the app it is an ordinary file in your care. Where you store it and who can read it is up to you.

Demo mode

Demo mode uses sample providers and sample addresses. It performs no real DNS updates and needs no credentials.

This website

This site is a handful of static files. It sets no cookies, stores nothing in your browser, and loads nothing from a third party: the fonts are served from this site, not from Google, so no request about you goes anywhere else. There is no analytics, no advertising and no tracking pixel.

The site is delivered by Cloudflare Pages. Like any web host, Cloudflare receives the data your browser sends in order to answer the request, including your IP address, the page requested, the time, and your browser's user agent, and keeps it briefly in server logs for operation and security. Cloudflare acts as a processor for the operator of this site.

From those server logs Cloudflare produces aggregate traffic figures the operator can see: how many pages were opened, roughly from which countries, and which sites linked here. That happens on Cloudflare's side, from records the request creates anyway. No script runs in this page for it, nothing is stored on your device, and single visitors are not followed from page to page.

The links to the App Store and to GitHub are ordinary links. Nothing is requested from those sites until you click one, and then their own privacy terms apply.

Your rights and how to reach a person

Because no personal data is collected on a server, there is nothing held about you to request, correct or delete. Everything the app stores is on your own device, and removing the app removes it, apart from credentials that a removed provider left in the keychain, which Settings reports and lets you clear deliberately.

You can still write and ask. For anything about your data, email info@business.pallus.io. You also have the right to complain to a data protection supervisory authority.

For bugs and feature requests, open an issue on GitHub; that is the faster route for those.
