Privacy Policy

Great news: in order to work, DaisyDisk doesn’t need to collect your personal data, and we try really hard to avoid that as much as we can. It’s just a disk tool, after all! 😀

To analyze your disk space usage, DaisyDisk scans metadata of your file system — namely, file names and sizes (without content) — and all data stays on your local computer. Nothing is sent out to the network.

We do use some bits of information about you for things like license management, and we want to be clear about what data we need and why.

Personal data we use

In free trial mode:

  • Your email address. We create a record for you in our database when you activate the free trial or buy a license, and store your license under that email. You can retrieve your license on our website using that email. Besides, we may occasionally use it to communicate with you regarding your use of the app, such as trial expiration, important product changes, availability of new features or versions of the app. (You can unsubscribe any time.)
  • Your computer’s hardware ID. It’s just an anonymous unique number of your computer, which our server uses to limit the number of Macs where you can install the license, according to our EULA.

In registered mode:

  • Your full name. Your name is engraved into your license key, and is used for verification when you register your license.
  • Your country code. When you buy a license, we get your country’s 2-letter code from our payment processor (currently FastSpring or Paddle) and keep it in our database, to be able to account on local regulations such as GDPR.
  • Besides, we’ll most likely have your external IP address, because it’s part of every client-to-server request in the Internet.

None of the above data is exposed online or passed to third parties, we use it solely for our internal license management purposes.

Marketing communication (optional)

We may occasionally use your email address (and your name if we have it) that you give us when you purchase a license or activate a free trial, to send you personalized notices and reminders about important updates, promos and time-limited discounts for our products. Besides, once in a while, we may send some hand-picked deals, which we arrange with fellow Mac developers and that we have assessed will be beneficial to you as a customer. You can unsubscribe from any or all our emails at any moment, using the unsubscribe link in each email.

Our website

Beside the app itself, we also have a website that serves as a store and a showcase for our product. Building an efficient website is not easy and requires us to track a lot of aggregate metrics of our audience, such as – which referrers people mostly come from, what they are looking for, which pages they like the most etc. Then we use this data to optimize our website for the audience. Like majority of websites, we currently use Google Analytics. When you come to our website, Google Analytics uses cookies in your browser to save and look up if you were there before, using a randomly generated, anonymous user ID. (But it can NOT identify your other personal data such as name, email etc.)

Our online advertising

Just like any other online business we have to buy ads on other websites, particularly on Facebook, Twitter and Google Seach. To make our ad budget more efficient, we want to target our ads only to people who already visited our website. This technique is called “remarketing” and works using another cookie. Similar to Google Analytics, whenever you visit our website, a randomly generated, anonymous user ID is saved in your browser and also passed to Facebook, Twitter and Google. When you afterwards visit Facebook, Twitter or Google Search, they will look up the cookie in your browser and therefore find out whether you might be interested in our ads on their platform.

Google, Facebook and Twitter in this case act as third-party “data processor”, which means they get anonymous user data from us, but they guarantee (using a special agreement) not to reduce the privacy promise we’re making to our own customers. The data is not exposed online and is used only for our business functions.

If you are in the EU, we will ask your consent before saving any tracking cookies in your web browser (as required by the GDPR).

Accepting payments from you

Being a small indie company, we prefer to outsource our store checkout to a well-established third party service, such as FastSpring or Paddle. They do for us all the heavy lifting of supporting different payment systems, international transactions, country-specific tax collection, fraud prevention and so on. In order to accept a payment from you, they will need to identify you using your personal data – they may ask your separate consent when you enter the checkout, with their own privacy policy. After the checkout it sends us your full name, email address and country code in order to create and deliver the license to you (see “Personal data we use” above).

How long do we keep your data?

Because we sell lifetime licenses for our apps, we also keep the data without limitation in time, unless you ask us to forget about you.

Can we forget about you?

Sure, if you want your data to be removed from our records, just send us a request to In response, we can send you all your data that we have and/or remove it from our database.

Who are that “we” after all?

We are Software Ambience Corp., an international company registered in Panama, with headquarters in Kyiv, Ukraine. Please feel free to get in touch with us via if you have any questions! 😎
