OptiFin is a browser-based collection of free calculators. No account or payment is needed, and calculator inputs are not saved to an OptiFin account or results database.
Calculator inputs are processed in your browser and are not submitted as calculator data.
OptiFin has no account system or database for storing calculator inputs and results.
Anonymous page-visit counts are recorded with GoatCounter; calculator inputs and results are never collected.
OptiFin does not require accounts and does not collect calculator inputs as submitted data. Avoid entering sensitive identifiers such as Social Security or bank account numbers into a calculator.
Calculations are performed in your browser. OptiFin does not send calculator inputs to a server for processing and does not collect results for analytics or benchmarking. Only anonymous page-visit counts are sent to GoatCounter.
OptiFin does not store calculator inputs or results in an account or results database. Inputs may remain temporarily in the active browser page; closing or reloading it may clear them.
We do not sell or share calculator inputs because they are not submitted to OptiFin. The website host receives technical requests needed to deliver the site; information may also be disclosed if required by law.
