Privacy policy

Last updated: November 1, 2026 · Publisher: Marko Nedic software

This policy covers all versions of the app: CAD Touch Lite for Windows from the Microsoft Store, the Android app from Google Play, and CAD Touch for iPhone and iPad from the App Store (the same app also runs on Mac computers with Apple silicon). Where the versions differ, the paragraph starts with "Windows", "Android" or "iPhone and iPad".

Summary

CAD Touch Lite does not collect, store or share any personal data. Your drawings are opened and processed only on your own device.

This is true for all versions. The app itself sends nothing unless you choose to share something, except what the app stores need for purchases: on Android, Google Play handles the subscription, and in versions that offer it, Google's billing component inside the app also sends technical diagnostic data to Google; on iPhone and iPad, the App Store handles the subscription (see "Purchases and subscriptions"). None of this reaches us; when something is bought, we only receive the stores' sales reports, described below.

Your drawings

Windows: DWG and DXF files you open are read locally. When a DWG file is opened for the first time, a converted DXF copy is saved in your Documents folder (Documents\CAD Touch Lite) so it can be reopened quickly. You can delete these copies at any time from the app or from File Explorer. No drawing, file name or file content is ever uploaded anywhere.

Android: You open a drawing with Android's file picker, or from another app with "Open with" or "Share"; the app gets access only to the file you choose. So that you can reopen it and keep notes on it, the app normally saves a copy of the file in its own folder on your device (the location is shown in the app under About) and keeps a prepared copy in its cache so that it opens again quickly. The original file is only read, never changed. Drawings are read entirely on your device: no drawing, file name or file content is uploaded anywhere. If you open a file from a cloud drive, that drive's app downloads it; CAD Touch Lite itself does not connect to the internet to open drawings.

iPhone and iPad: You open a drawing with the Files picker, or from another app with "Open in" or "Share"; the app gets access only to the file you choose. The app saves a copy of the file in its own folder, which you can see in the Files app under On My iPhone (or On My iPad) › CAD Touch › Drawings, and keeps a prepared copy in its cache so that it opens again quickly. The original file is only read, never changed. Drawings are read entirely on your device: no drawing, file name or file content is uploaded anywhere. If you open a file from iCloud Drive or another cloud service, that service downloads it; CAD Touch itself does not connect to the internet to open drawings.

Notes and pictures

Windows: Notes you pin to a drawing, and the pictures you attach to them, are stored only on your device, in a folder beside the converted drawing (Documents\CAD Touch Lite). "Take photo" opens the Windows Camera app; the app itself does not use the camera. A note leaves your device only when you choose Share, Print or Save, and then it goes only where you send it. Removing a drawing from the app moves its notes to the Recycle Bin.

Android: Notes and their pictures are stored only on your device, in the app's folder beside the drawing copy. "Take photo" opens your device's camera app, which hands the photo to CAD Touch Lite; the app has no camera permission and cannot use the camera by itself (some camera apps also keep their own copy in your gallery). "Add picture" opens Android's photo picker, and the app receives only the pictures you select. The app keeps its own copy of each picture as a JPEG without location (GPS) or other metadata. If a photo cannot be added to a note, the app keeps it in your gallery folder Pictures/CAD Touch (on Android 8 and 9, in the app's folder) and tells you where it is. A note leaves your device only when you choose Share, Print, Save picture, Save as PDF or Copy text, and then it goes only where you send it. Drawings you remove from the app, and pictures you delete, go to the app's own trash and are deleted permanently after 30 days.

iPhone and iPad: Notes and their pictures are stored only on your device, in the app's Drawings folder beside the drawing copy. "Take photo" uses the camera inside the app, so the first time iOS asks whether CAD Touch may use the camera; the app uses it only while you take a photo for a note, and you can turn this off at any time in Settings › CAD Touch. "Add picture" opens Apple's photo picker, which needs no permission: the app receives only the pictures you select and cannot see the rest of your photo library. The app keeps its own copy of each picture as a JPEG without location (GPS) or other metadata, and it does not save photos to your photo library. A note leaves your device only when you choose Share, Print, Save picture, Save as PDF or Copy text, and then it goes only where you send it. Drawings you remove from the app go to the app's own trash and are deleted permanently after 30 days.

Measurements

Android, iPhone and iPad: Measurements you keep on a drawing (distances, perimeters, areas, diameters and point coordinates, in versions that save them) are stored only on your device, in the app's folder beside the drawing copy, together with that drawing's notes. They are saved as a small text file with the measured points in the drawing's own coordinates; the drawing file itself is never changed. Measurements that are not saved (without Pro the app keeps only one, and never saves it) stay on the screen only while the drawing is open and are never written to storage. Measurements are not uploaded anywhere. You can tap a measurement and delete it, or delete all measurements of a drawing; removing a drawing from the app moves its saved measurements to the app's trash together with its notes, where they are deleted permanently after 30 days.

Data we collect

Windows: None. The app contains no analytics, tracking, advertising or crash-reporting services, and it does not require an account with us.

Android: The same applies. Versions that offer the Pro subscription contain the Google Play Billing Library, a component made by Google, which sends technical diagnostic data about the billing component to Google (see "Purchases and subscriptions"). Because Google counts data that a component inside an app sends as data collected by that app, the app's Data safety section on Google Play lists it as diagnostics. We do not receive it. Separately, if you have allowed your device to share usage and diagnostics data with Google, Android may report crashes and freezes of your apps, including this one, to Google, and Google shows developers these reports in Google Play Console. That is a setting of your device, not part of the app.

iPhone and iPad: None. The app contains no analytics, tracking, advertising or crash-reporting services and no third-party code that sends data; the app's own code makes no internet connections. Purchases go through Apple's StoreKit, which is part of iOS (see "Purchases and subscriptions"). The app's App Privacy section on the App Store therefore says "Data Not Collected". If you have chosen to share analytics with app developers in Settings › Privacy & Security › Analytics & Improvements, Apple may share crash reports and usage statistics with us in anonymous form; that is a setting of your device, not part of the app.

Android test versions: If you take part in a test of the Android app, we know the e-mail address of the Google account that you gave us for the test list or that joined our test group, and we use it only to run the test. Google Play tells testers that it collects certain data about their use of a test version and shares it with the developer; in Google Play Console we see statistics such as installs and crashes, and the feedback you choose to send us.

Purchases and subscriptions

Windows: Subscriptions, the free trial and the one-time purchase, when they become available, are sold and managed by the Microsoft Store. Payment information is handled by Microsoft under the Microsoft Privacy Statement. The app only asks the Microsoft Store whether you own one of them; we do not receive your payment details.

Android: Measuring and notes are the paid Pro features. When the subscription is available in the version you have (test versions may have everything unlocked), it is sold and managed by Google Play, and payment information is handled by Google under the Google Privacy Policy. The app asks Google Play whether your Google account has an active subscription and stores the answer on your device (whether Pro is active and when this was last checked), so that measuring and notes keep working for up to 14 days without a connection to Google Play. We do not receive your name, e-mail address or payment details. You can cancel the subscription at any time in the Google Play app under Payments & subscriptions → Subscriptions.

Android: Google Play gives every developer reports about the sales of their apps. For each order they contain the order number, date, product, price and taxes, the device model and the buyer's country, and for some orders the region, city and postal code. They contain no names or e-mail addresses. We use these reports only for accounting and taxes and keep them as long as tax and accounting rules require. If you contact us about a purchase and give us its order number or the e-mail address of your Google account, we can look up that order in Google Play Console, for example to refund it.

iPhone and iPad: Measuring and notes are the paid Pro features. The subscription is sold and managed by Apple through the App Store, with your Apple Account; payment information is handled by Apple under the Apple Privacy Policy. The app asks the App Store whether your Apple Account has an active subscription and stores the answer on your device (whether Pro is active and when this was last checked), so that measuring and notes keep working for up to 35 days without a connection to the App Store. We do not receive your name, e-mail address or payment details. Apple gives developers sales reports with totals per product, country and date, without names or contact details. Refunds are requested from and decided by Apple. You can cancel the subscription at any time in Settings › your name › Subscriptions.

Android: Versions that offer the subscription contain the Google Play Billing Library, Google's component for purchases in apps. It sends technical diagnostic data about its own work to Google over an encrypted (HTTPS) connection. Google does not publish exactly what this data contains. The app never passes your drawings, notes, measurements or pictures to it. Google processes this data under the Google Privacy Policy; we do not receive it and cannot see or delete it.

Permissions

Android: Versions without the subscription ask for no permissions at all. Versions with the subscription have these permissions, all of which Google's billing component requires: "Google Play billing service", "full network access" and "view network connections" (the last two are used only by Google's billing component; the app's own code makes no internet connections), plus one internal permission that only this app itself can use. The app has no permission for the camera, microphone, location, contacts or your files: photos come from your camera app or the photo picker, and drawings from the file picker or from the app you open them from.

iPhone and iPad: The only permission the app asks for is the camera, and only when you tap "Take photo". It does not ask for access to your photo library, location, contacts, microphone or other apps' files.

Settings stored on your device

Windows: The app stores a few local settings (chosen language, measurement units per drawing, list of recently opened drawings) and a cache that lets drawings you have already opened reopen faster. All of it is kept in your user profile and never leaves your device.

Android: The app stores its settings (language, display unit, units per drawing, light or dark background), the list of drawings in its folder, the place you were looking at while another app is in front, a few technical notes (for example how long drawings took to load, to estimate the next loading time) and, in versions with the subscription, whether Pro is active. All of it stays in the app's storage on your device. The app does not use Android's cloud backup. If you move to a new phone with Android's device-to-device transfer (Android 12 and newer), your drawings, notes, measurements, pictures and settings can be copied to the new phone as part of that transfer.

iPhone and iPad: The app stores its settings (display unit, units per drawing, light or dark background), the list of drawings in its folder, the place you were looking at if iOS closes the app in the background, a few technical notes (for example how long drawings took to load) and whether Pro is active. The language is the one you choose for the app in iOS Settings or in the app. All of it stays in the app's storage on your device. If you back up your device to iCloud or to a computer, iOS includes the app's drawings, notes, measurements, pictures and settings in that backup, as it does for other apps; caches are not backed up.

Ratings

Windows: The app may occasionally ask whether you would like to rate it. The rating window belongs to the Microsoft Store; what you write there is sent to Microsoft, not to us.

Android: The Android app may ask once whether you would like to rate it, after you have made a few notes, using Google Play's own rating window; Google decides whether that window appears. In the released app, what you write there goes to Google, not to us, and the app does not learn whether or how you rated it. In a test version of the app, Google shares your rating and comment privately with us as test feedback. If you write a review on Google Play, Google publishes it under your Google profile name, and we can read it and reply there.

iPhone and iPad: The app may ask once whether you would like to rate it, after you have made a few notes, using Apple's own rating window; Apple decides whether that window appears, and the app does not learn whether or how you rated it. The "Rate on the App Store" button in About opens the App Store. Ratings and reviews you write there go to Apple, which publishes reviews under your App Store nickname.

Keeping and deleting your data

Android: We run no server and keep no data about you, apart from Google Play's sales reports and, if you take part in a test, your test e-mail address (both described above); ask us and we remove you from a test list. Everything the app stores is on your device and stays there until you delete it:

• In the app: remove a drawing from the list to delete its copy together with its notes, measurements and pictures. Removed items stay in the app's trash for 30 days and are then deleted permanently. To delete a single measurement, tap it and choose "Delete measurement"; you can undo this for a few seconds, after that it is gone.
• Everything at once: in Android Settings → Apps → CAD Touch Lite → Storage, choose "Clear storage" (on some devices "Clear data"). This immediately deletes all drawing copies, notes, measurements, pictures, settings and caches of the app.
• Uninstalling the app deletes all of it as well, unless you choose to keep the app's data when Android asks (Android 10 and newer).
• Pictures kept in your gallery folder Pictures/CAD Touch, and files you saved or shared elsewhere, are not part of the app's storage; delete them in your gallery or file manager.
• Data held by Google (your subscription, your payments and the billing component's diagnostic data) is kept and deleted under the Google Privacy Policy; you can manage your Google data in your Google Account.

iPhone and iPad: We keep no data about you, apart from Apple's sales reports (described above). Everything the app stores is on your device:

• In the app: remove a drawing from the list to delete its copy together with its notes, measurements and pictures. Removed items stay in the app's trash for 30 days and are then deleted permanently. To delete a single measurement, tap it and choose "Delete measurement".
• In the Files app you can also see and delete the drawings and their notes under On My iPhone (or On My iPad) › CAD Touch › Drawings.
• Everything at once: delete the app (touch and hold its icon, then Remove App › Delete App). This deletes all drawing copies, notes, measurements, pictures, settings and caches of the app. Copies inside an older iCloud or computer backup are deleted when that backup is replaced or deleted.
• Data held by Apple (your subscription and your payments) is kept and deleted under the Apple Privacy Policy; you can manage it at privacy.apple.com.

Security

Android: The app keeps your drawings, notes, measurements and pictures in its own folder on your device. On Android 11 and newer, other apps normally cannot open that folder; on older versions, apps that you have allowed to access your device's storage can read it. On every version, a computer connected to the device by USB can see it. Settings and the subscription status are kept in the app's private storage. We run no server that receives your data.

iPhone and iPad: The app's files are kept in its own container, which other apps cannot open; you can see the Drawings folder in the Files app. Settings and the subscription status are kept in a part of the app's storage that the Files app does not show. iOS encrypts the app's data with your device passcode (Data Protection).

This website

This website is a static page hosted on GitHub Pages. It sets no cookies and runs no analytics or advertising scripts. As with any website, the hosting provider (GitHub) receives your IP address and browser details when a page loads, and Microsoft receives a request when the "Get it from Microsoft" button image loads.

If you arrive through a link that carries a campaign tag (for example ?cid=…), the tag is added to the Microsoft Store link you click, so that Microsoft's reports can show us, in total numbers only, which source sent visitors. The tag is not stored on your device.

Children

The app does not knowingly collect any information from anyone, including children.

CAD Touch Lite is a tool for working with technical drawings and is not directed at children.

Your rights

You can ask us what information we hold about you (normally none, apart from the store sales reports described above), and ask us to correct or delete it where the law allows; sales records may have to be kept for tax purposes. You can also complain to the data protection authority of your country (in Serbia: the Commissioner for Information of Public Importance and Personal Data Protection).

Changes

If this policy changes, the updated version will be published at this address with a new date.
