Privacy Policy
Last updated: 4 September 2026
Information you provide
If you create an account, SFS Tools may process your email address and profile details you choose to provide. If you use cloud features, saved calculations, favorites and documents you explicitly upload may be stored for your account.
Browser-side tools
Many calculators and utilities are designed to run in your browser. A tool may use third-party browser libraries where needed to provide its function.
Account and cloud services
Authentication and cloud data are provided through Supabase. Data required for those features is sent to the configured Supabase project.
Your controls
You can remove individual saved calculations, favorites and uploaded documents through your account where those controls are available. For additional privacy or account requests, use the Contact page.
Security
Do not upload or share passwords, OTPs, secret API keys or other authentication secrets. No internet service can guarantee absolute security.
Financial information
Calculator results are estimates. SFS Tools does not guarantee lending, insurance, tax, legal or investment outcomes.
Changes
This policy may be updated as the service changes. The updated date on this page indicates the current published version.
