Privacy Policy

Last Updated: September 14, 2026

At PercentageCalculator.dev, accessible from https://percentagecalculator.dev, we are committed to protecting your privacy and delivering a frictionless browsing experience. This Privacy Policy describes how we handle information when you visit and use our website.

1. Data Processing & Privacy First

PercentageCalculator.dev is built as a client-side utility:

  • Calculation Inputs Processed Locally: We do not collect, record, or store your mathematical inputs. All calculations, numbers, and formulas are executed entirely in your browser using local JavaScript. No calculation values are ever transmitted to or stored on our servers.
  • No User Accounts: You can use this utility without creating an account, logging in, or providing any personal identifiable information (PII).

2. Analytics & Telemetry

We believe in an open web without intrusive tracking:

  • This website does not use cookies.
  • Our telemetry does not read or write to your local browser storage.
  • We do not track your browsing behavior across third-party websites or build personal profiles.
  • We collect only high-level, aggregate telemetry (such as total page visits and referring sites) to measure performance and uptime. This measurement is completely cookieless, stores no personal information, and discards IP addresses so individual visitors cannot be identified.

3. Infrastructure & Hosting Logs

Our hosting and edge infrastructure records standard server access logs (including request timestamps and technical diagnostic data) strictly for network security, DDoS mitigation, and server performance. This data is processed transiently and is never combined with analytics.

4. Third-Party Disclosures & Advertising

We do not sell, rent, or monetize your personal information. We do not run programmatic advertising networks, tracking pixels, or third-party behavioral profiling scripts.

5. Children’s Privacy

PercentageCalculator.dev is an educational calculation utility and does not collect personal information from children or adults alike.

6. Updates to This Policy

We may periodically update this policy to reflect modifications to our site architecture or infrastructure. Any revisions will be published on this page with an updated revision date.
