Who we are

This privacy policy applies to Resin Calculators (resincalculators.com), a free educational website providing calculators and resources for resin crafters.

For questions about this privacy policy, please contact us at support@resincalculators.com.

What data we collect and why

Information you provide directly

Contact form submissions: If you contact us via email or contact form, we collect:

• Your email address (to respond to you)
• Your name (if you provide it)

How we use it: Only to respond to your inquiry. We don't add you to mailing lists or use your email for marketing. We keep correspondence for up to 1 year for reference, then delete it.

Calculator input data

Calculator inputs: When you use our calculators, you enter project dimensions, amounts, and other values.

How we handle it: All calculator operations happen in your browser only. We do not transmit, store, or have access to your calculator inputs or results. Your project data is private and stays on your device.

Automatically collected data (analytics)

We use Google Analytics in privacy-friendly mode to understand how people use our site. This helps us improve calculators and identify issues.

What we collect:

• Pages you visit and time spent on site
• Which calculators you use (not the values you enter)
• Browser type, device type, and screen size
• Referring website (how you found us)
• General location (city/country level, not precise)
• Anonymized IP address (last digits removed for privacy)

What we DON'T collect:

• Your full IP address (we anonymize it)
• Personal identifying information
• Calculator inputs or results
• Cross-site tracking data
• Advertising IDs or profiles

What we never collect

We do NOT collect:

• User accounts or login credentials (we don't have accounts)
• Payment information (the site is free)
• Social security numbers, financial data, or sensitive personal information
• Precise geolocation or GPS data
• Biometric data
• Health information

Cookies and tracking technologies

What are cookies?

Cookies are small text files stored on your device by websites you visit. They help websites remember information about your visit.

Cookies we use

We use minimal cookies:

Google Analytics cookies: These track anonymous usage statistics to help us improve the site. We've configured Google Analytics with:

• IP anonymization enabled
• Advertising features disabled
• User-ID tracking disabled
• Data sharing with Google disabled

No advertising cookies: We do not use cookies for advertising, remarketing, or cross-site tracking.

Third-party cookies

When you click affiliate links to external sites (Amazon, retailers, etc.), those sites may set their own cookies. We have no control over third-party cookies. Review their privacy policies for details.

Controlling cookies

You can control cookies through your browser settings:

• Block all cookies: Most browsers allow you to refuse all cookies. The calculators will still work.
• Delete cookies: You can delete cookies at any time through browser settings
• Third-party cookies: You can block third-party cookies while allowing first-party cookies

Blocking Google Analytics cookies means we won't know you visited, but all calculators will function normally. We respect your choice.

Third-party services and data sharing

Services we use

We use these third-party services to operate the website:

Google Analytics: Anonymous usage statistics. Google's privacy policy: https://policies.google.com/privacy

Cloudflare Pages: Website hosting and content delivery. Cloudflare's privacy policy: https://www.cloudflare.com/privacypolicy/

Affiliate networks: When you click affiliate links, the destination site may track the referral. We don't control their privacy practices.

We don't sell or rent your data

We never sell, rent, or trade any user data to third parties. We don't have much data to sell anyway—by design.

When we might share data

We may disclose information only in these limited circumstances:

• Legal requirements: If required by law, court order, or legal process
• Safety concerns: To prevent fraud, abuse, or harm to people or property
• Business transfer: If the website is sold or merged, data may transfer to new owner

How we protect your data

Security measures

We implement reasonable security measures to protect data:

• HTTPS encryption: All traffic to our site uses secure HTTPS connections
• Secure hosting: Website hosted on Cloudflare's secure infrastructure
• Limited data collection: The best security is not collecting data in the first place
• No user accounts: No passwords or credentials to be compromised

No system is 100% secure

While we take reasonable precautions, no internet transmission or electronic storage is completely secure. We cannot guarantee absolute security of data.

Children's privacy

Our website is intended for general audiences. We do not knowingly collect personal information from children under 13.

Resin crafting involves chemicals and tools that require adult supervision. If you're under 13, please use this site only with parent or guardian permission.

If we discover we've collected data from a child under 13, we'll delete it immediately. If you believe we have data from a child, please contact us.

International users and data transfers

This website is operated from the United States. If you access the site from outside the U.S., your information may be transferred to, stored in, and processed in the United States.

U.S. data protection laws may differ from those in your country. By using this website, you consent to the transfer of information to the U.S. and processing under U.S. law.

We comply with GDPR requirements for European users and handle data according to privacy-protective standards regardless of location.

Do Not Track signals

Some browsers include "Do Not Track" (DNT) features. Currently, there is no industry standard for responding to DNT signals.

We respect your privacy choices. If you use privacy tools like browser tracking protection or analytics blockers, they will prevent our analytics from collecting data, and we respect that.

Changes to this privacy policy

We may update this privacy policy from time to time to reflect changes in our practices or legal requirements. Changes will be posted on this page with an updated "Last updated" date.

For significant changes, we may provide more prominent notice (such as a banner on the homepage).

Your continued use of the website after changes constitutes acceptance of the updated privacy policy.

We encourage you to review this policy periodically to stay informed about how we protect your privacy.
