Privacy policy

Mudry Studio (“Mudry”, “we”) develops and distributes desktop software for Windows and operates the website at https://mudry.tech. For any privacy question, contact romanmodrytskyi@gmail.com.

Our applications do not transmit telemetry, usage statistics, crash reports, diagnostic information or update pings. There is no analytics SDK and no reporting endpoint of any kind.

The one exception is not ours: where an app offers an optional Pro upgrade, the purchase and its licence check are handled by the Microsoft Store, using Microsoft’s own systems and privacy policy. We receive no personal information from that process — only whether the current machine holds a licence.

All data an application processes — file names, folder structures, settings, history — is stored locally on your device and never leaves it. Uninstalling an application removes its settings from your machine.

You do not need to take our word for this. A firewall configured to log blocked connections will show no outbound traffic from our applications themselves.

We count pageviews so we know which articles are worth writing more of. It is our own software, running on our own server, and it stores no personal data:

• No cookies, and nothing stored in your browser for analytics. Nothing to consent to, so we do not ask.
• Your IP address is never stored. It is combined with your browser’s user-agent string and a secret that changes every day, then hashed. The result cannot be reversed into an IP address, and because the secret rotates daily it cannot be used to recognise you tomorrow.
• No third parties by default. No Google Analytics, and our own pageview counting shares nothing with anyone — the figures exist in one database that we run. The one exception is opt-in: if you consent to it, we load Google’s advertising tag to measure ad performance. See section 5 for exactly what that does.
• Referrers are reduced to a hostname. We record that you arrived from, say, google.com — never the full address, which can contain the words you searched for.
• Do Not Track is honoured. If your browser sends a Do Not Track or Global Privacy Control signal, nothing at all is recorded.

What this produces is a count of pages and visits. It cannot answer who you are, and we could not tell you even if asked.

Likes work the same way, with one deliberate difference. To stop the same browser liking an article repeatedly, the like is stored against a hash of your IP address and browser string that does not rotate daily — a rotating one would let the same browser like the same page again every morning. That value is still impossible to reverse into an IP address, is never linked to your pageviews or to anything else, and is used for nothing except answering “has this browser already liked this page?”. No cookie is set, and you can like anonymously without an account.

Beyond the opt-in advertising tag described in section 5, we run no other advertising scripts and set no other advertising cookies.

A single functional preference — your light or dark theme choice — is stored in your browser’s local storage. It never leaves your browser and is not readable by us.

Our hosting provider processes standard server request logs (IP address, user agent, requested URL, timestamp) as a necessary part of serving the site securely. These logs are used only for security and reliability, are not used to build profiles, and are retained for a short period.

If you email us, we receive your email address and whatever you write. We use it only to reply and to fix the problem you reported. We do not add you to any list without your explicit request.

If you use the contact form, your name, email address and message are stored in our database so the message is not lost, and so we can find it again when replying. This is the only place on this site that holds personal information, and it holds exactly what you typed — nothing is inferred, enriched or shared. Ask us to delete a message and we will.

If you subscribe to our newsletter, we store your email address for that purpose alone. Every message includes a one-click unsubscribe link, and unsubscribing deletes your address.

We distribute our applications through the Microsoft Store. When you download from the Store, Microsoft processes that transaction under its own privacy policy, which we do not control. We receive only aggregate, anonymous download counts from Microsoft — never information about individual users.

Optional in-app purchases (the Pro upgrade) are likewise processed entirely by Microsoft. We never see your payment details, billing address or Microsoft account — only whether a licence is present on the device.

Google Ads, opt-in only. If you consent — in the banner shown on your first visit, or later through “Cookie preferences” in the footer — we load Google’s advertising tag (gtag.js) to measure how our ad campaigns perform. This is the one part of this website that is not first-party: Google sets its own cookies and processes what it collects under its own privacy policy, not ours. The tag never loads before you say yes, declining changes nothing else about how the site works, and you can withdraw consent at any time — the footer link clears your stored choice and the tag stops loading on your next page view.

Outside of that one opt-in tag, we do not sell, rent or share personal information with anyone, and there is no data broker involved at any point.

Depending on where you live, you may have rights to access, correct, export or delete personal data we hold about you, and to object to its processing. Because we hold almost nothing — at most an email address you gave us — these requests are usually straightforward.

Email romanmodrytskyi@gmail.com and we will respond within 30 days.

Our software is not directed at children under 13, and we do not knowingly collect information from them. Since we collect no personal information through our applications at all, this is largely academic.

If this policy changes materially, we will update the date at the top of this page and note the change in our changelog. We will not retroactively reduce the protections described here for data already collected.
