When something leaves your computer

Every request to our licence server also carries the app's version number. The app never sends files, folders, passwords or card details.

Licences and our licence server

• The computer identifier is a code the app works out on your computer from your Windows installation and system drive. It contains no name and no files, and it changes if Windows is reinstalled. Because it can be linked to a licence, we treat it as personal data, even where we only keep it encrypted.
• Your name is optional. If you write one, we use it only to greet you in our emails, exactly as you wrote it. If you don't, we greet you by your email address.
• Using your licence on another computer. You give the licence email in the app, and, if that email has a licence, we send a code to it, so only whoever reads that email can use the licence. An email without a licence gets nothing. The email shows the computer's name in Windows, so you can tell which computer asked. The code is valid for 10 minutes, only once, and we keep it only as a fingerprint (a hash), never as the code itself. Each code request and each wrong code is kept with the email and the computer identifier for 30 days, for the hourly limits and the one-hour block after six wrong codes.
• Buying. You pay on a Stripe page. The seller is Sold through Link, LLC, of the Stripe group: it receives your payment details, country and address directly, under its own privacy policy, and sends you the receipt and the invoice. From Stripe we keep, for each payment, your email, your country, the amounts (with the tax and any refund), the type of payment and its status, and the computer it was for. Never your card details, and not the name or VAT number you may give on the payment page. A refunded purchase cancels its licence.
• What we keep for a licence: your email, the name you gave us (if any), your country and language, the plan and its dates, what you paid, the identifiers and Windows names of the computers it is used on (three, or more if you bought more), the keys issued for them, the emails we sent you, a history of what was done to the licence and by whom (issued, used on a computer, released, details corrected), and your answers about promotions, with the date, the channel and the version of the text, as proof of what you chose.
• Requests. The app talks to our licence server when you open the PREMIUM window, check your licence or activate it. If this computer has a licence, it also confirms it whenever needed. For each of these requests we keep the time, what was asked and the answer, with the computer identifier encrypted, for support and to stop abuse. It never includes your IP address.
• Visits. When the app talks to our server at your request (the prices, the licence status, the data we hold), we note one visit per computer, however many requests it makes in that visit. We keep the computer identifier only encrypted, the kind of computer (normal or giveaway), the first and last visit, and how many visits came from each country (in the United States, from each state) and from each version of the app. We use it only to count where our visitors come from and how often they come back, never to know who you are: we only ever look at totals, and we never link a visit to a licence or a purchase. A computer's line is deleted once it has not visited for 12 months; the totals by day, week, month and year, by country, by US state and by version of the app, stay, and they carry nothing about any computer.
• Usage statistics. When the app starts, it sends a random number of this installation, created by the app and not taken from your computer or from you, with the app's version, edition and language. The server works out the country (in the United States, the state) from the connection and does not keep the IP address. We keep each installation's line, with the number encrypted, until it has sent nothing for 12 months; after that only totals remain. You can turn this off in About → Send usage statistics.
• Where our users are, roughly. The first time a computer contacts our server, the server works out an approximate area from the connection (country, region, nearest town) and adds one to a count for that area and month. The count is not linked to your computer or to you. The IP address is read only for that moment, to find the area and the country (and, in the United States, the state) for Visits, and for the limits per address it is kept in memory for at most an hour and never written down. The area comes from a database kept on our own server: IP geolocation by DB-IP. For a mobile connection, the area is usually the operator's, not yours.
• The giveaway edition. Before anything is sent, the app tells you exactly what will be sent, and you can refuse. If you agree, we keep only this computer's identifier and the time of activation, so we know how many activations there were and so you can upgrade to the full Premium later at a special price. If you refuse, nothing is sent.
• Emails. We send them from explorerfocus@intrepidparallel.com, through our company's Microsoft 365. There are two kinds:
  • about your licence: the codes, the keys, and the reminders 30 days, 7 days and on the day a licence for a period ends (licences never renew by themselves). These come with the licence. A copy of each, except the codes, is kept in our company mailbox for about 2 years;
  • promotions (news and offers about ExplorerFocus and the other mBrothers programs): only if you tick the box when you give us your email. The box is never ticked for you. Each email has a link to stop them, and without the box ticked we never write to you about anything but your licence.
• Backups. Our licence data is copied every day, and each copy is kept for 30 days. We also keep the three most recent full copies, on a computer of our management and in our company's Microsoft 365 (OneDrive), both encrypted.

Why we use your data

• To give you the licence you bought or activated, including the giveaway licence, to send you its codes, keys and reminders, and to check it when you ask and whenever needed to confirm it (the contract between us).
• The request records, to support you and stop abuse; and the visits and the area counts, to know where our users come from and how often they come back (our legitimate interest). You can ask us to delete any of these.
• The codes and their limits, to protect the licences from misuse (our legitimate interest).
• What you write to us, to answer you and follow up (our legitimate interest).
• Promotions, only with your consent, which you can withdraw in any of them.
• The usage statistics, to know how many installations use the app, in which versions, languages and countries (our legitimate interest). You can turn them off in About → Send usage statistics.

How long we keep it

Our server deletes what has reached its limit once a day, by itself. Anonymising removes your email, your names, the names of your computers, the text of the emails and the codes; the licence keeps working.

Where it is stored

Our licence server is in the Netherlands, in the European Union, and its daily backups stay on it. Our emails are sent from our company's Microsoft 365, where our mailbox also is (Brevo, in the European Union, only as a backup). The three encrypted full copies are kept on a computer of our management and in our company's Microsoft 365 (OneDrive). Payments are handled by Stripe and by Sold through Link, LLC, under their own privacy policies. Stripe, Link, GitHub, Hugging Face, Microsoft and the other services named in the table above may handle data outside the European Union, under their own safeguards.

Your rights

You can ask us to see, correct or delete your data, to stop using it, or to receive a copy of it. Write to explorerfocus@intrepidparallel.com and we will answer within one month. If we delete a licence record, we can no longer send codes for it, renew it or move it to another computer, and for the giveaway the special price is lost.

Everything else stays on your computer

The app stores its settings, your configured folders and trees, and your saved connections locally, in your Windows user profile. This information never leaves your device except in the cases above.

Cloud connections (Dropbox, OneDrive, Google Drive)

Connecting a cloud account is optional. When you do:

• Authentication uses the provider's official OAuth 2 flow (with PKCE). You sign in on the provider's own page; the app never sees your password.
• The app receives an access/refresh token that grants access to your own account only. The token is stored locally and encrypted with Windows DPAPI; it is never sent to us or any third party.
• All file operations happen directly between your computer and the provider's API. Your files do not pass through us.

Permissions requested, and why:

• Dropbox — account_info.read (show which account is linked), files.metadata.read (browse folders/files), files.content.read (preview/open/download), files.content.write (upload, create folders, rename, move, delete your files).
• OneDrive (Microsoft Graph) — Files.ReadWrite and offline_access, to browse and manage your own OneDrive files and keep the connection working between sessions.
• Google Drive — the Drive scope, to browse and manage your own Drive files.

You can disconnect at any time inside the app, and you can revoke access entirely from your provider's account/security settings (Dropbox connected apps, Microsoft account apps, Google account third-party access).

Remote servers (SFTP / FTP / FTPS / WebDAV)

If you add a remote server, its host, username and credentials are stored locally and encrypted with Windows DPAPI. Connections are made directly from your machine to that server. We never see your servers or credentials.

Local files

The app reads and writes the files and folders you choose to work with, on your own device, just like Windows Explorer. Nothing is uploaded anywhere unless you explicitly perform an upload to a destination you connected. Previews are rendered without going to the network: a document that points at remote content does not fetch it.

Encrypted vaults

A vault is a set of encrypted files in a folder you choose, on your own disk. The password and the recovery words stay on your machine — they are never sent anywhere, and we cannot open a vault for you.

Giving a vault a drive letter needs the Dokany driver. If you let the app install it, the installer is downloaded from that project's own releases on GitHub, and installing it is a separate confirmation.

Photos and location

The photo X-ray, “Near…”, reading the text of an image and finding faces to cover them all happen on your computer, without internet. Only “Show on map…” goes out: it asks first, and only then sends the photo's coordinates to OpenStreetMap to draw the map. When a photo has a location, every box that saves a copy asks whether the location goes with it.

Listen and write

The ear, which writes down what is said, and the translator work on your computer. They don't come with the program: the first time you use them, the app asks for permission and downloads them once. The models come from Hugging Face, and the engines that run them come from GitHub and nuget.org. Each file is pinned to a version and checked after it is downloaded. As with any download, those sites see the request. After that, the sound, the text and the translations never leave your computer, and no internet is needed.

Software updates

The app can check for new versions by fetching a small version.json file hosted on GitHub Pages. This is an ordinary web request and sends no personal data. You can turn automatic checks off in the app's settings.

This website

This website is hosted on our own server, in the Netherlands, and uses no cookies. We count visits and clicks on the download buttons without cookies and without keeping your IP address. The program itself is downloaded from GitHub.

Data sharing

We do not sell or rent your data. Apart from our licence server, the email service and the counting described above, the only parties your data reaches are the services you connect to, directly.

Children

ExplorerFocus is a general-purpose utility and is not directed at children under 13.

Changes

If this policy changes, the new version is posted here with a new date. If the change affects data we already keep, we tell you in the app.
