Privacy Policy

1. Who we are and what this covers

BuildMate Calc is an iPhone calculator for feet, inches, fractions and common jobsite conversions. This policy explains how we handle information from the BuildMate Calc app, this website and optional support communications. For privacy questions or deletion requests, contact bluesolarc@gmail.com.

2. What stays on your device

Core calculations, calculation history, saved items and preferences are stored locally on your iPhone using Apple's standard device storage. We do not receive them unless you deliberately include them in a support message, copy them or export them yourself. You can clear local calculation history from the app's Settings screen.

3. What we do not collect automatically

We do not require an account and do not use advertising identifiers, cross-app tracking, third-party advertising SDKs or analytics SDKs. We do not collect your contacts, precise location, photos, microphone data, payment-card information, calculation history or saved measurements in the background. We do not sell or share personal information for advertising.

4. Feedback and support diagnostics

When you voluntarily choose the in-app feedback or email-support option, we may receive the information you enter, such as your email address, subject, message and any attachment or screenshot you choose to send. To help us reproduce and fix a reported problem, the feedback flow may also include limited technical details: your device model, iOS version, BuildMate Calc version and build number, app language or region, and the date and time of the report. We call these “support diagnostics.”

Support diagnostics are collected only with your feedback submission; they are not collected while you simply use the calculator. They are used only to respond to you, investigate the reported issue, maintain app reliability and prevent support abuse. Do not include passwords, payment details, government IDs, client information or other sensitive material in a support message.

5. How feedback is sent and shared

Feedback is sent by email to bluesolarc@gmail.com. Your email provider and ours process the message as part of delivering email, under their own privacy terms. We do not disclose support messages or diagnostics to advertisers or data brokers. We may share the minimum information necessary with a service provider only when needed to operate email, secure the service or comply with law, and only subject to appropriate confidentiality and data-protection obligations.

6. Purchases

Pro is a one-time, non-consumable in-app purchase. Apple processes payment, billing and purchase restoration. We do not receive or store your payment-card number or other payment credentials. A local purchase status may be kept on your device so Pro features can remain available and be restored.

7. Retention and deletion

Local app data remains on your device until you delete it or remove the app. We keep support emails and associated diagnostics only for as long as reasonably necessary to resolve the request, maintain a support record, protect the service or meet legal obligations. You may ask us to delete a support conversation and its associated diagnostics by emailing bluesolarc@gmail.com from the address used to contact us. We may need limited information to verify and complete the request, and may retain information where law requires it.

8. Your choices and rights

Feedback is optional and is not required to use the calculator or unlock Pro. You can choose not to send a support message, remove optional details before sending it, and request access to, correction of or deletion of information in a support conversation. Depending on where you live, you may have additional privacy rights. To exercise them, contact us at bluesolarc@gmail.com. We do not sell or share personal information for cross-context behavioral advertising.

9. Security and international processing

We use reasonable administrative and technical measures appropriate to the small amount of information we handle. No method of electronic transmission or storage is completely secure. Because email and its service providers may operate internationally, a support message may be processed in countries other than the one where you live.

10. Children's privacy

BuildMate Calc is a general-purpose utility and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has sent us a support message, contact us and we will take appropriate steps to delete it.

11. Changes to this policy

We may update this policy when our data practices, the app or applicable requirements change. We will post the revised policy here and update the “Last updated” date. If a change materially affects how we use feedback information, we will provide additional notice where appropriate before applying it.
