Privacy Policy

Short version: the tools on UNQIRO process the files you select and the text you enter in your browser, on your device. These contents are not uploaded to us. If you allow it, UNQIRO also counts which tools are used, whether they finish and which links between the tools and the Format Lab are followed, without anything from your files or text. Like every website, the pages themselves are delivered over the internet, here through Cloudflare, which processes technical data of each request.

Local processing of files and text

When you select a file or enter text for one of the tools, the processing is performed by code running in your browser. Depending on the tool, this can be, for example, an image, a PDF, an audio or video file, a Windows program or library file, an icon file, structured data or plain text. UNQIRO does not intentionally transmit the contents of the selected file to a UNQIRO server or to any other file-processing service. The contents of files and text processed by the tools are not sent to a processing server. UNQIRO has one small server-side endpoint, for the optional usage statistics described below; it never receives the contents of your files or text.

The file tools can also inspect program, library and application package files, for example Windows EXE and DLL files (and related Windows files such as MUN files) and Linux AppImage packages, as well as icon files such as ICO and ICNS. These files are read only as data: the supported file structures and icon resources are parsed in your browser to extract the icons. UNQIRO does not execute or launch the software or load its code; an AppImage is never run. For large program or package files, only the parts needed to find the icons are read. Their contents are not intentionally sent to a UNQIRO processing server.

The utility tools work the same way. Text and structured data you enter or paste, for example JSON, CSV, Base64 or URL-encoded text, are processed by code running in your browser. QR codes are generated there from the content you enter, and UUIDs, timestamp conversions and hashes are created there as well. A file you select for the hash generator is read in your browser to calculate its hash. UNQIRO does not intentionally transmit these contents to a UNQIRO server or to any other processing service, and they are not intentionally included in the ordinary website requests described below.

While a tool works, your browser may temporarily hold your text or data derived from your file in its memory, for example decoded image data, PDF pages, decoded audio samples, the parts of a program file that were read, the finished result and temporary links to it (object URLs), including memory used by background workers and WebAssembly code. This stays in your browser and is released when you remove the file or clear the text, choose another file or close the page. A result is only kept on your device when you download it or copy it to the clipboard.

You can check this in your browser's developer tools: in the network tab, no request carrying your file or your text appears while you use a tool. If you have allowed usage statistics, you will also see small requests to /analytics/event. Each contains only the event, the name of the tool, for example compress-image, and for a link between a tool and the Format Lab also the name of the Format Lab page, for example zip/cannot-open.

Program code loaded for the tools

Some tools load additional program code when you use them, for example the PDF engine, the media library for audio and video files, or the MP3 encoder (JavaScript and WebAssembly). These files come from unqiro.tools itself, like the pages. Loading them is an ordinary download of program code to your browser; it does not send your file anywhere. The open-source components involved are listed on the open-source page.

Website delivery through Cloudflare

UNQIRO is hosted on Cloudflare Pages, and DNS and all web traffic to unqiro.tools are handled by Cloudflare (Cloudflare, Inc. and its affiliates). When you open a page, your browser connects to Cloudflare's network. To deliver, secure and operate the site, Cloudflare processes technical information about each request. Depending on the Cloudflare service and logging involved, this can include your IP address, the requested address and resources, the time of the request, your browser's user agent and other request metadata. Files you select for the tools are processed locally and are not intentionally included in these ordinary website requests.

According to its privacy policy, Cloudflare acts as a processor on behalf of its customers for customer logs, and as a controller for some other data it processes, for example to secure its network. Cloudflare operates a global network, so request data may be processed outside the European Union, including in the United States. For such transfers Cloudflare states that it participates in the EU-U.S. Data Privacy Framework and otherwise relies on standard contractual clauses. Details are in the Cloudflare privacy policy.

Cloudflare shows the operator overviews of traffic and security events for the site in its dashboard, based on this request data. This is not a tracking script. Apart from the optional usage statistics described below, which stay off unless you allow them, no analytics code runs on the pages.

Cloudflare also asks browsers to report failed connections to the site (network error logging). If your browser supports this and a connection fails, it may send an error report to Cloudflare with technical details such as the address, referrer, request method, protocol, error type and timing. According to Cloudflare, it derives network, country and metro area from the client IP address when such a report arrives, keeps that IP address only in memory for the duration of the request and does not log it in the network error logging pipeline; Cloudflare states that it does not store personally identifiable information from these reports.

The legal basis for this processing is our legitimate interest in delivering the website reliably and securely (Art. 6(1)(f) GDPR).

Usage statistics

To learn which tools are actually used and whether they work, UNQIRO can count how often each tool is started and finishes, and how often the links between the tools and the Format Lab (our technical pages about file formats) are followed. This is optional and off until you allow it. After you have used a tool successfully for the first time, a short question below the tool asks whether you allow it. The use that led to the question is not counted, and nothing is counted if you choose No thanks or do not answer.

If you allow it, your browser sends a short message to unqiro.tools/analytics/event when a tool starts working on your request, when it finishes with a result, and when you follow the link from a Format Lab page to its tool or from a tool to a Format Lab page. The message contains only the event (tool_started, tool_completed, format_action or format_guide), the tool's name, for example extract-zip, and for the two link events the Format Lab page, for example zip/cannot-open. It does not contain your files or their contents, file names, paths, sizes or formats, the text you entered, results, error details, or any identifier for you, your browser or your visit. Page views, downloads and copying are not counted.

The message is received by a small program that Cloudflare runs for us (a Pages Function). It checks the message and stores only the event, the tool's name and, for the link events, the Format Lab page, together with a timestamp and a sampling value that Cloudflare's Analytics Engine adds itself. Like every request to the site, the message reaches Cloudflare with ordinary connection data, such as your IP address and details of your browser (see above). UNQIRO does not copy the IP address, browser details, country, referring page or any other request data into the usage statistics. The stored counts are kept for three months.

The usage statistics use no cookie and no identifier, and UNQIRO does not fingerprint your browser. We see how often each tool was started and finished and how often each link was followed; we cannot tell who used a tool, and we cannot follow anyone across pages or visits.

Your answer is kept in your browser (see Cookies and browser storage) so that you are not asked again. You can change it at any time with one click under Usage statistics at the bottom of every page. If you turn usage statistics off, no further messages are sent from that moment. Counts already stored contain no identifier, so they cannot be traced back to you or your browser, and we cannot find or delete individual entries.

We use usage statistics only after you have allowed them (§ 165 Abs. 3 TKG 2021 and, to the extent personal data are processed, Art. 6(1)(a) GDPR). You can withdraw your consent at any time with effect for the future (Art. 7(3) GDPR). Cloudflare processes this data for us as our processor under its data processing agreement; the information on transfers outside the European Union above applies.

Cookies and browser storage

UNQIRO does not set its own cookies and does not use session storage or IndexedDB. It keeps one value in your browser's local storage, and only once you have answered the usage statistics question: your choice, "allowed" or "denied", so that you are not asked again. It contains no identifier, no date, no tool history and nothing from your files or text, and it stays in your browser. If you clear this site's data in your browser, it is removed and you are asked again after your next successful use. In our checks, normal page responses from Cloudflare set no cookies either. Cloudflare's security features can set cookies that Cloudflare describes as strictly necessary in particular situations, for example after a security check of a suspicious request; see Cloudflare's cookie list.

Advertising and other tracking

UNQIRO does not show ads, uses no other analytics service and does not track you across websites. If this changes, this policy will be updated first, and consent will be asked for where it is required.

Contacting us by email

If you write to us, we use your email address and message to answer you and keep them only as long as needed for that conversation (Art. 6(1)(f) GDPR). Email sent to mail@sthb.me is received and stored through the email service of Proton (Proton AG, Switzerland); see the Proton privacy policy. Please do not attach files you do not want to share.

Your rights

Under the GDPR you have the right to access, rectification, erasure and restriction of processing of your personal data, the right to data portability and the right to object (Art. 15 to 21 GDPR). To exercise them, write to mail@sthb.me. You also have the right to lodge a complaint with a supervisory authority; in Austria this is the Austrian Data Protection Authority (Datenschutzbehörde).

Where we rely on your consent (usage statistics), you can withdraw it at any time under Usage statistics at the bottom of every page. Because the tools do not send your files or the text you enter to us, we hold no copies of them and cannot provide or delete any. The usage statistics contain no identifier, so we cannot find, provide or delete entries relating to a particular person.
