Privacy Policy

1. Who we are

Build Specs is a mobile and web reference toolkit for jobsite professionals, published by Corvora ("we", "us"). This Privacy Policy explains what information the App processes and why.

2. Information we do not collect

We do not collect or process:

• Your name, email address, phone number, or any other contact information.
• Your precise or approximate location.
• Your contacts, photos, photo library, calendar, microphone, camera, or other device sensors.
• Face data, biometric face data, face geometry, facial landmarks, faceprints, face-recognition data, or biometric templates.
• Advertising identifiers (IDFA) or other cross-app tracking identifiers.
• Behavioral analytics or session recordings.

The App contains no third-party advertising networks and no marketing trackers.

3. Information stored on your device

The App stores the following information locally on your device, never sent to us:

• Your saved calculator inputs, layouts, and recent calculations (e.g. propane, water, voltage drop history).
• Your UI preferences (e.g. which mode of a calculator was last used).
• The timestamp of your first launch, used to track the 10-minute free preview window. This is stored in the iOS Keychain (or Android Keystore) so it persists across reinstalls.

Clearing the App's data or uninstalling the App will remove this information (with the exception of the first-launch timestamp, which intentionally persists in the Keychain to prevent abuse of the free preview).

Build Specs does not record user-created video, does not collect face data, and does not detect, analyze, identify, map, extract, or create biometric templates from faces. Because Build Specs does not collect face data or recordings, there is no face data or recording data for us to retain on our servers.

4. Subscription processing

To validate your subscription status, the App uses RevenueCat as a third-party subscription platform. RevenueCat receives an anonymous user identifier generated on your device, plus the receipt of any purchase you make, in order to confirm whether your subscription is active. RevenueCat's privacy policy is available at revenuecat.com/privacy.

The actual purchase transaction is handled by Apple through the App Store. Apple's handling of payment information is governed by Apple's privacy policy.

5. What we do not share

Because we do not collect personal data, we have nothing to sell, share, or rent to third parties. We do not exchange data with data brokers and do not participate in any cross-context behavioral advertising.

6. Children

Build Specs is intended for adult professionals and is not directed at children under 13. We do not knowingly collect any information from children.

7. Your rights

Because we do not store personal information about you on our servers, there is no account to access, correct, or delete. To remove the App's locally-stored data, uninstall the App. To cancel a subscription or request a refund, use your Apple ID Account Settings.

Residents of California (CCPA), the EU/UK (GDPR), and other jurisdictions with similar laws have the same effective rights — there is simply nothing for us to disclose, correct, or delete on the server side. If you have any questions, contact us at the address below.

8. Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date at the top of this page.
