The short version. The DevCleaner app runs on your Mac and does its work locally. It does not have accounts, does not collect personal data, and the only thing it ever sends is a single anonymous number after a cleanup (how many bytes were freed) to power the public counter, which you can switch off in Settings.
The website, like most sites, uses analytics and an advertising pixel. That part involves cookies and third-party services (Google, Microsoft, Reddit). The details, and how to opt out, are below.
DevCleaner is an independent project operated by David Tereba, based in Prague, Czech Republic. For anything in this policy, including any request about your data, contact hello@devcleaner.app.
This policy covers both the DevCleaner macOS application and the website at devcleaner.app. They are treated separately below because they behave very differently.
DevCleaner is a desktop utility. Scanning your disk, calculating sizes, and deleting caches all happen locally on your Mac. The contents of the files it finds, their paths, and the tools you use never leave your computer.
devcleaner.app/api/stats.php. That single number is added to a global total shown on the homepage. No identifiers, no file paths, no tool names, no IP address is stored with it. You can turn this off entirely in Settings → General → Privacy.The app has no account system, no login, no advertising, and no third-party analytics SDKs. It does not track how you use it.
When you visit devcleaner.app we use a small set of third-party services to understand traffic and to measure the effect of advertising. These set cookies and may receive your IP address, browser/device information, and the pages you view.
| Service | Purpose | Data involved | Their policy |
|---|---|---|---|
| Google Analytics 4 | Aggregate traffic and usage statistics | Cookies (_ga), truncated IP, pages viewed, device/browser |
policies.google.com |
| Microsoft Clarity | Heatmaps and aggregated session insights to improve the site | Cookies, interaction events, device/browser | privacy.microsoft.com |
| Reddit Pixel + Conversions API | Measure ad performance and build advertising audiences | Cookies (_rdt_uuid), a click id, hashed IP, user agent, the fact that a page or download happened |
reddit.com/policies |
| Google Fonts | Serving the site's typefaces | IP address (when fonts load from Google's servers) | policies.google.com |
| Web hosting | Serving the site and downloads | Standard server logs (IP, user agent, time), kept briefly | — |
When you download the app, the request passes through a small counter that increments a total number of downloads. It stores only a running count. It does not store your IP address or build a profile of you.
We advertise DevCleaner on Reddit. To know whether those ads actually lead to downloads, we use the Reddit Pixel (in your browser) together with Reddit's Conversions API (on our server). When you arrive from a Reddit ad, a click identifier is stored in a cookie; if you later download the app, our server reports that download to Reddit so the ad can be credited.
Where personal data such as your IP address or email is sent to Reddit through the Conversions API, it is hashed (irreversibly scrambled) before it leaves our server. This data is used for ad measurement and to build audiences for future ads. You can limit ad personalisation in your Reddit account settings.
The cookies on this site come from the analytics and advertising services listed above. None of them are required for the site to function, they exist to measure usage and advertising. You can block or delete cookies in your browser settings at any time; the site will still work.
For visitors in the European Economic Area, we process website data on these bases under the GDPR:
The anonymous freed-space number sent by the app is not personal data, as it cannot be linked back to you.
Google, Microsoft, and Reddit are based in the United States, so using their services means some data is processed outside the European Economic Area. These providers rely on recognised transfer mechanisms such as the EU–US Data Privacy Framework and Standard Contractual Clauses.
If you are in the EEA or UK, you have the right to access, correct, delete, restrict, or object to the processing of your personal data, to data portability, and to withdraw consent at any time. To exercise any of these, email hello@devcleaner.app.
You also have the right to complain to a supervisory authority. In the Czech Republic this is the Office for Personal Data Protection (Úřad pro ochranu osobních údajů).
DevCleaner is a tool for developers and is not directed at children. We do not knowingly collect data from children.
If this policy changes, the new version will be posted here with an updated date at the top. Material changes will be reflected in the app's release notes or on the site.
