Privacy Policy

This policy explains what information 401kcalc.app may receive, how it may be used, and the choices available to visitors.

Last updated: September 25, 2026

1. Scope

This Privacy Policy applies to the 401kcalc.app website and its calculator tools. 401kcalc.app is operated as an independent educational resource. This policy does not govern third-party websites or services that you visit independently.

2. Information you provide

The calculator does not require an account. When you enter planning information, such as salary, age, balance, contribution rate, or employer match details, that information is processed in your browser to calculate the scenario you requested. Please do not enter account numbers, Social Security numbers, passwords, or other sensitive personal information.

If you email 401kcalc.app, we may receive your email address, the contents of your message, and related delivery metadata. Do not send confidential financial or account information by email.

3. Browser storage and share links

Calculator settings may be stored in your browser’s local storage under the key 401kcalc_inputs_v1. This storage remains on your device unless you clear it or use browser controls that remove site data.

Some calculator inputs may be encoded in the page URL so that a scenario can be shared or restored. A shared URL can therefore contain financial planning inputs. Review a URL before sharing it, and avoid sharing links containing information you do not want another person to see.

CSV exports are generated in your browser. The exported file may contain salary, contribution, and projected financial values; its handling after download is outside our control.

4. Technical information

Our hosting provider may process standard technical information such as IP address, browser and device information, requested pages, timestamps, and error logs to deliver the site, maintain security, and diagnose problems. This information is handled as part of operating the website and may be retained according to the provider’s operational and security practices.

5. Fonts, advertising, and analytics

The site currently loads the Inter font from Google Fonts. When your browser requests that font, Google may receive technical information such as your IP address and browser information under Google’s own privacy terms.

The site may display advertising placeholders or advertising content. If advertising or analytics providers are enabled, they may use cookies, device identifiers, or similar technologies to serve or measure content. We will update this policy when a provider is added and the specific practices are known. Any provider-specific collection should also be governed by that provider’s privacy policy.

6. How information may be used

Information may be used to operate and secure the website, respond to inquiries, maintain the calculator, understand aggregate usage, improve content, and comply with legal obligations. We do not sell personal information.

7. Cookies and local storage

The calculator can function without advertising cookies, but browser local storage may be used to remember calculator inputs. Third-party font, advertising, or analytics services, if enabled, may use their own cookies or similar technologies. You can control cookies and site data through your browser settings; disabling storage may remove saved calculator scenarios.

8. Security and retention

We use reasonable technical and organizational safeguards designed to protect information, but no method of transmission or storage is completely secure. We retain information only as long as reasonably needed for the purposes described here, to resolve inquiries, to maintain security, or to meet legal requirements.

9. Your choices

You can clear browser site data, avoid sharing scenario URLs, and choose not to send email. Depending on where you live, you may have rights to request access, correction, deletion, or restriction of personal information. Contact us to make a request; we may need to verify your identity before responding.

10. Children

This website is intended for adults seeking retirement planning information. It is not directed to children, and we do not knowingly collect personal information from children through the calculator or email contact.

11. Changes to this policy

We may update this policy as the website, providers, or legal requirements change. The date at the top of this page identifies the latest version. Continued use of the website after an update means the revised policy applies from that time forward.
