Open DWG and DXF drawings. Accurately.
A fast, private drawing viewer. Model space and every layout, layers, measuring with snaps, markup and export. Your files never leave your device.
Coming soon to the App Store.

Draw on the drawing without changing the original file.
Export

Your drawings. Drawings are opened, measured, marked up and exported on your device. Cyanfold has no server and does not receive your files, file names or their contents.
No account. Cyanfold does not ask for your name, e-mail address or any sign-in.
Daily limit and purchases. The free-tier count is stored in your own iCloud Keychain, which we cannot read. Purchases are handled by Apple; the app checks them on your device.
Ads (iPhone and iPad free tier only). Ads are provided by Google AdMob. Google may collect device identifiers, IP address, approximate location and ad interactions to show and measure ads. The advertising identifier is used only if you allow tracking when iOS asks. Where the law requires it, you are asked for consent first, and you can change your choice in the app’s settings. See Google’s Privacy Policy. There are no ads on Mac or with Pro.
Crash reports. If you choose to share analytics with app developers in your device settings, Apple sends us anonymous crash reports.
Support e-mails. When you write to us, we receive what you send, including any drawing you choose to attach. We use it only to answer you and delete it when it is no longer needed.
Your rights. You can ask us to access or delete any data we hold about you by writing to [email protected]. Data on your device is removed when you delete the app.
Children. Cyanfold is not directed at children under 13.
Changes. If this policy changes, the new version will be published on this page.

Subscriptions. Pro is an auto-renewing subscription, charged to your Apple Account. It renews unless cancelled at least 24 hours before the end of the current period. You can manage or cancel it in your Apple Account settings.
Your files. Your drawings, markups and exports remain yours.
