Privacy Policy

Last updated: August 20, 2026

This is a starting template, not legal advice. Before publishing, have it reviewed by a lawyer familiar with your jurisdiction (and GDPR/CCPA if you have EU or California visitors). It's written to accurately describe what CalcoTools actually does today — update it if the app's functionality changes.

Overview

CalcoTools ("we," "our," "the site") is a browser-based collection of calculators and converters. This policy explains what data is and isn't collected when you use it.

What we do NOT collect

  • No accounts, no sign-up required to use any calculator. There is no registration, login, or user profile.
  • No calculation data. Nothing you type into any calculator — salary figures, health measurements, passwords you generate, dates, or any other input — is transmitted to us or stored anywhere. It exists only in your browser's memory for as long as the page is open, and is discarded the moment you navigate away or close the tab.
  • No cookies. CalcoTools does not set or read browser cookies. (A cookie-preference banner is present anyway, in advance of any future feature that would need one — see the Cookie Policy.)
  • No third-party analytics or advertising trackers are currently embedded in the site.

What we DO collect

  • Per-browser usage counters, private to you. The site tracks how many times you've opened each tool and how many times you've visited the site, stored only in your own browser's local storage, to power a personal "recently used" list and this device's own display. These are not shared, aggregated, or visible to anyone else — a previous version of this policy incorrectly described them as shared/global counters; they are not, and never leave your device. You can clear them at any time from within the app or by clearing your browser data.
  • Your region preference (e.g. India or United States, for currency and unit defaults), stored the same way — locally, privately, only to remember your choice on return visits.
  • Your cookie-preference choice, stored locally with a timestamp once you interact with the preference banner.
  • Your email address, only if you join the waitlist. The "Go ad-free" button opens a form for CalcoTools Pro updates. If you submit it, your email address is sent to our email-list provider (configured via a form endpoint) to add you to that list — nothing else about your session is sent with it. We use it only to email you about CalcoTools Pro; we don't sell or share it. You can ask us to remove you at any time (see Contact, below).

Third-party services

Two features currently call external services directly from your browser:

  • Currency Converter requests live exchange rates from a public rates API (Frankfurter, which itself sources from dozens of central banks). The amount and currencies you're converting are sent to that service to compute the result; we don't see or log this.
  • Image to Text (OCR) downloads its text-recognition engine (software, not your data) from a public CDN the first time you use it. Your image itself is never uploaded anywhere — recognition runs entirely in your browser after the engine downloads.

The QR Code Generator previously sent entered text to a third-party image service; it no longer does — QR codes are now generated entirely in your browser.

Planned: server-side processing for two tools (not live yet)

Two tools in active development — Background Remover and PDF to Word — will need to briefly process your file on a server, because the conversions they do can't run in a browser. When they launch, this policy will be updated to state plainly, before you use them: what's uploaded, that it's automatically deleted within 60 minutes, that it's never used for any purpose beyond producing your result, and where it's processed. Every tool on the site is labeled either "🔒 Runs entirely in your browser" or "☁️ Processed on our servers" so this is always clear on the tool page itself, not just in this policy.

Advertising (not active yet)

The site reserves space for ads in its layout so that turning them on later won't shift content around, but no ad network is connected and no ad-related data is collected today. If that changes, this policy and the cookie-consent banner will be updated first, and ad-related cookies will default to declined until you actively accept them.

Data retention

Locally-stored data (recently-used tools, region preference, cookie choice) persists in your browser until you clear it or clear your browser data — we have no way to access, back up, or delete it remotely, because it's never sent to us. Waitlist email addresses are retained until CalcoTools Pro launches or you ask to be removed, whichever comes first.

Your rights

Because we don't collect most data at all, there's typically nothing to access, export, correct, or delete on our end beyond a waitlist email address, if you've given us one. If you have questions about what's described here, or want your waitlist email removed, contact us at [insert contact email].

Changes to this policy

We may update this policy as the site's features change. Material changes will be reflected in the "Last updated" date above.
