Privacy Policy

Last updated: June 2026

1. Information We Collect

RentCostCalc.com is designed with your privacy in mind. All calculations are performed locally in your web browser. We do not collect, store, or transmit any personal information to our servers through the calculator tools.

However, we do use third-party services that may collect information:

• LocalStorage: Your calculator inputs may be saved in your browser's localStorage to improve your experience (so you don't have to re-enter data). This data never leaves your device.
• Google AdSense & Google Funding Choices CMP: We use Google AdSense to display advertisements and Google Funding Choices to provide a GDPR-compliant consent banner. Google may use cookies and similar technologies to serve ads based on your visits to this and other websites. You can manage your ad personalization and consent choices through the cookie banner or by visiting Google Ads Settings.
• Chart.js (CDN): We load Chart.js from a CDN to render calculator charts. No personal data is collected by Chart.js.

2. How We Use Information

We do not use any personally identifiable information (PII) because we do not collect it. The site is designed to be privacy-first: all calculations are performed locally in your browser, and your inputs are stored only in your browser's localStorage. We do not transmit any personal data to our servers.

3. Cookies

This site uses cookies and similar technologies for the following purposes:

• LocalStorage: To save your calculator inputs locally (not a cookie, but similar purpose). This data never leaves your device.
• Advertising cookies and identifiers: Google AdSense and Google Funding Choices may use cookies and similar technologies for ad personalization, measurement, and fraud prevention. You can review and change your consent choices at any time through the cookie banner.

You can control cookies and localStorage through your browser settings. Most browsers allow you to refuse or delete cookies and clear localStorage. However, some features of the site may not function properly without localStorage.

4. Third-Party Services

We use the following third-party services:

• Google AdSense & Google Funding Choices: We display ads through Google AdSense and use Google Funding Choices to manage consent for users in the EEA/UK and other regions requiring GDPR-style consent. Google Privacy Policy.
• Chart.js (CDN): For rendering calculator charts. No personal data is collected by Chart.js.

5. Your Rights (CCPA & GDPR)

California Residents (CCPA)

Under the California Consumer Privacy Act (CCPA), California residents have the right to:

• Know what personal information is being collected about them
• Know whether their personal information is sold or disclosed and to whom
• Say no to the sale of personal information
• Access their personal information
• Request deletion of their personal information
• Not be discriminated against for exercising their CCPA rights

Since we do not sell personal information and do not collect PII on our servers, these rights are largely handled by Google and other third-party services we use. You can opt out of ad personalization via Google Ads Settings or the cookie consent banner.

European Residents (GDPR)

Under the General Data Protection Regulation (GDPR), EU residents have the right to:

• Access their personal data
• Rectify inaccurate personal data
• Erase their personal data ("right to be forgotten")
• Restrict processing of their personal data
• Data portability
• Object to processing

Since we do not collect PII on our servers, there is no personal data to access or delete. For advertising-related data processed by Google, we display a Google Funding Choices consent banner that allows you to accept or decline personalized advertising cookies and other data uses in accordance with GDPR and IAB TCF requirements. For questions, contact us at the email below.

6. Data Security

All calculations happen locally in your browser. We do not transmit or store any personal information on our servers. However, no method of transmission over the Internet or electronic storage is 100% secure. We strive to use commercially acceptable means to protect any data, but we cannot guarantee absolute security.

7. Children's Privacy

This site is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us and we will delete it.

8. Changes to This Policy
