Privacy Policy

The app has no accounts. You do not register, you do not sign in, and you never give us a name, an email address or a phone number to use it. Nothing in the app is tied to an identity.

Everything you type is written to a database inside the app on your own device: • Filament and printer profiles (names, prices, power draw, purchase price) • Saved calculations, including the figures they were made with • Your settings (language, currency) • A counter of how many quote PDFs you created this month This data is not uploaded anywhere. We cannot see it, and we cannot recover it for you.

Quote PDFs are generated on your device. The file is written to the app's temporary folder and then handed to the iOS share sheet, where you decide what happens to it — send it to a customer, save it to Files, or discard it. It is never uploaded to us.

Subscriptions are sold and billed by Apple. Your payment details never pass through the app and we never see them. To know whether your subscription is active, the app uses RevenueCat, a subscription management service that validates Apple's purchase receipts. RevenueCat receives an anonymous identifier generated for your installation and the status of the purchase. It does not receive your name, your email address or any of the data you entered in the app. RevenueCat acts as our processor; see revenuecat.com/privacy.

The free tier may show advertisements delivered by Google AdMob. To serve them, Google may process device identifiers, including the advertising identifier, along with technical data such as device type and coarse region. On iOS this only happens with your permission: the system asks whether the app may track you, and if you decline, ads are served without the advertising identifier. You can change this at any time in iOS Settings under Privacy & Security. See policies.google.com/technologies/ads for how Google uses this data. Subscribers see no advertisements at all.

The app contains no analytics SDK. We do not track how you use it, which screens you open or what you calculate. Apple provides us with aggregate, anonymous App Store statistics such as download and crash counts. These cannot be traced back to an individual user.

The app is a business tool for people selling 3D prints. It is not directed at children under 13, and we do not knowingly collect data from them.

Because your data stays on your device, you are in control of it: • Delete individual profiles or saved calculations in the app • Delete the app to remove the database and everything in it Under the GDPR and the Turkish KVKK you have rights of access, rectification and erasure. In practice we hold no personal data to hand over or erase, but you are welcome to write to contact@emresozen.dev with any question about this.

If the app starts doing something new with data, this page changes with it and the date at the top is updated. Material changes will also be noted in the App Store release notes.

Questions about this policy or about how the app handles your data: contact@emresozen.dev. You can also use the support form at emresozen.dev/apps/support.
