Privacy Policy

Last updated: January 25, 2026

Nuts & Bolts - Guide ("we", "our", or "the App") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our mobile application.

        Summary: Our app works entirely offline. We do not collect, store, or transmit any personal data. The free version displays advertisements provided by Google AdMob.
    

Information We Collect

The App itself does not collect any personal information. All fastener reference data is stored locally on your device and the app functions completely offline.

We do not require:

Account registration or login
Personal information (name, email, phone number)
Location data
Contact information
Camera or microphone access

Advertising

The free version of the App displays advertisements provided by Google AdMob. Google AdMob may collect certain information to serve personalized ads, including:

Device identifiers (Advertising ID)
IP address
General location (country/region level)
App usage data related to ad interactions

This data is collected and processed by Google according to their privacy policy. You can learn more about Google's data practices at: https://policies.google.com/privacy

The PRO version of the App does not display advertisements and therefore does not involve any ad-related data collection.

In-App Purchases

The App offers a one-time PRO upgrade through Google Play. All purchase transactions are processed by Google Play and are subject to Google's privacy policy. We do not have access to your payment information.

Local Data Storage

The App stores the following data locally on your device:

Your favorites/bookmarks (if using PRO version)
App preferences (theme settings, unit preferences)
PRO purchase status

This data is stored only on your device and is not transmitted to any server. Uninstalling the App will remove all locally stored data.

Data Sharing

We do not sell, trade, or share any user data with third parties, except as described in the Advertising section above for the free version of the App.

Children's Privacy

The App is not directed at children under 13. We do not knowingly collect any personal information from children. The App contains no user-generated content or social features.

Data Security

Since the App operates entirely offline and does not collect or transmit personal data, there is no risk of data breach from our services. Your preferences and favorites are stored securely on your device.

Your Rights

Since we do not collect personal data, there is no personal data to access, modify, or delete from our systems. To remove locally stored app data, simply uninstall the App from your device.

To opt out of personalized advertising, you can:

Adjust your device's ad settings (Settings > Google > Ads)
Upgrade to the PRO version to remove all ads

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
