Summary
3D Printing Toolkit is an offline calculator and troubleshooting-reference app for 3D printing. The app itself does not collect, store, or transmit any personal information. It has no user accounts, no sign-in, and no analytics. The entire catalog ships inside the app and works without a network connection.
The app does use two Google services that may process some data, described below.
Information the app collects
None directly. We do not ask for your name, email, location, contacts, photos, or any other personal data, and the app stores nothing about you on our servers (we operate no servers).
On-device data (Pro features)
If you use the optional Pro features, the app saves your filament profiles, printer profiles, and calculation results on your device only (in the app's private storage). This data never leaves your device, is not transmitted to us or anyone else, and is removed if you clear the app's data or uninstall the app.
Third-party services
Google AdMob (advertising)
The free version of the app shows banner ads through Google AdMob. To serve ads, the AdMob SDK may collect and process information such as your device's advertising identifier, device and app information, and approximate (coarse) location, in order to show and measure ads. This data is collected by Google, not by us. In the EEA/UK (and other regions where required) a consent prompt is shown before personalized ads are served, via Google's User Messaging Platform.

- How Google uses information from apps that use its services: policies.google.com/technologies/partner-sites
- AdMob / Ads: support.google.com/admob/answer/6128543
Ads are not shown to users who have purchased the Pro upgrade.
Google Play Billing (purchases)
The optional one-time "Pro" upgrade is processed by Google Play Billing. Your payment is handled entirely by Google; we never receive or store your card or payment details. Google's handling of that data is governed by Google's Privacy Policy.
Permissions
The app requests only:
- Internet and network state — used solely to load ads (free version).
Your choices
- Reset or limit ad tracking: you can reset your advertising ID or opt out of ad personalization in your device settings (Settings → Privacy → Ads on Android).
- Remove ads entirely: purchase the one-time Pro upgrade.
- Delete your saved data: clear the app's storage in device settings, or delete individual saved profiles/results inside the app.
- Region consent (EEA/UK): where required, a consent prompt is shown before personalized ads are served.
Children
The app is a general-audience tool and is not directed to children under 13. We do not knowingly collect personal information from children.
Data security
The app stores no personal data on any server. Saved profiles and results are kept in the app's private on-device storage. Any data exchanged with Google's ad and billing services is transmitted over encrypted (HTTPS/TLS) connections.
Data deletion
The app holds no account and stores no personal data on our servers, so there is nothing for us to delete. On-device saved data can be removed at any time by deleting items in the app or clearing the app's storage. For any privacy question or request, contact us at email us.
Changes
We may update this policy from time to time. Material changes will be reflected by updating the "Effective date" above and posting the revised policy at the same URL.
