Privacy Policy

Who we are

Dummy Files (dummyfiles.com) is a free dummy file generator. Dummy Files is responsible for the data described here. Contact: contact@dummyfiles.com.

Your files never leave your browser

Every file is generated on your device with your browser. The file, its contents and the file name you type are never sent to us or to anyone else.

So that the download page can show a preview, your browser keeps the most recent file in its own storage (IndexedDB) and remembers which page you came from (session storage). This data stays on your device. The stored file is replaced when you generate a new one, and you can delete it at any time by clearing this site's data in your browser.

Analytics and cookies

We use Google Analytics 4 to understand how the site is used, for example which formats and sizes are popular and which pages people start from. It runs with Google Consent Mode, and you choose in the cookie banner:

• Before you choose, or if you reject: Google Analytics sets no cookies. It still receives cookieless pings, such as that a page was viewed and basic browser and device information, without an identifier that recognises you. Google uses them for aggregated statistics.
• If you accept: Google Analytics sets first-party cookies (_ga and _ga_*, kept for up to 2 years) to tell new and returning visits apart.
• Events we send: the file format, the requested size, the number of pages, rows or columns, the page path and short error messages. We never send the file name you type or any file content.
• Never used: advertising cookies, ad personalisation and Google signals are turned off.

Google processes this data as our processor and may transfer it outside the European Economic Area, under the EU-US Data Privacy Framework and standard contractual clauses. Google Analytics 4 does not store IP addresses. Event data is kept for the retention period set in our Google Analytics account (at most 14 months).

You can change your choice at any time with Cookie settings at the bottom of every page. Rejecting also removes the Google Analytics cookies from your browser.

Other storage on your device

• df_consent in local storage remembers your cookie choice, so the banner does not reappear.
• df_source in session storage remembers the page you generated from, for the Back link.
• The latest generated file in IndexedDB, as described above.

These are needed for the site to work and are never sent to us.

Hosting

The site runs on Cloudflare Workers. To deliver and protect the site, Cloudflare processes technical data such as your IP address and the requested URL, for example in security logs. This is based on our legitimate interest in running a secure website.

Feedback and email

When you send the feedback form ("Request feature"), we store what you choose and write: the topic, your message, your email address if you add one, and the page and file format you were on. This is saved in a Cloudflare D1 database and sent to our inbox via Cloudflare Email Routing. We use it only to improve the site and, if you gave an email, to reply. We delete feedback after 12 months.

To stop spam, we also keep a one-way hash of your IP address, made with a secret key, so the raw IP is never stored. It is used only to limit how many messages one visitor can send and is deleted after 24 hours.

If you email us directly, we use your address and message only to reply, and delete them when they are no longer needed.

Your rights

Depending on where you live (for example under the GDPR in the EU and UK, or the CCPA in California), you can ask for access to, correction or deletion of your personal data, restrict or object to its use, and withdraw consent at any time without affecting earlier processing. You can also complain to your data protection authority. We do not sell personal data. Write to contact@dummyfiles.com and we will reply within 30 days.

Changes

If this policy changes, we update the date at the top of this page. Questions are welcome at contact@dummyfiles.com or on the contact page.
