Privacy

CalcShelf is designed around simple, privacy-light calculators.

• For basic calculators, raw inputs/results are not stored, logged, placed in URLs, or sent to analytics.
• Calculations run in your browser where practical.
• We do not send raw calculator inputs or result values to analytics.
• No account is required to use the basic calculators.

Future email reports, ads, or affiliate features will require separate review so they do not break this promise.

Copy, print, and export features

Some richer calculators include local-only actions such as copying a summary or printing the page. Those features are meant to help you move the result into your own notes without sending the raw numbers to CalcShelf. If a future feature sends a report by email, saves a scenario, or shares a link with embedded values, it should be clearly labelled and opt-in.

Why this matters

Calculator inputs can reveal budgets, debts, home-buying plans, business revenue, project costs, infrastructure details, or other sensitive context. CalcShelf’s default is to make the page useful without turning those numbers into stored data.
