Privacy Policy
This policy explains how SopidoCalc, operated by SopidoTech LTD, handles information when you use sopidocalc.com. It should be read together with the Cookie Policy and Privacy & Cookie Choices.
Calculator inputs
Most deterministic calculators run in your browser. SopidoCalc does not intentionally transmit or store those calculator inputs on its server by default. A particular tool that needs external data may make a network request to a named provider; the page should identify that dependency and the information needed for the request.
Information you send to us
If you use the contact form, we process the name, email address, subject and message you submit so we can receive, secure and respond to your enquiry. We may also process limited technical data needed to prevent abuse, such as an IP-derived rate-limit identifier and Cloudflare Turnstile verification information. Do not send passwords, payment-card details, medical records or other highly sensitive information through the general contact form.
Technical logs and security
Our hosting provider and security services may create normal server, access, error and security logs containing information such as IP address, timestamp, requested URL, user agent and response status. These logs are used for availability, troubleshooting, abuse prevention and security. We aim to retain only what is reasonably necessary for those purposes.
Cookies, local storage and preferences
SopidoCalc may use essential storage for security and preference functions, including a short-lived contact-form session and a privacy-choice record. Optional analytics or advertising storage should not be activated merely because you visited the site. See the Cookie Policy for categories and the current status of optional technologies.
Cloudflare and contact protection
The contact form is designed to use Cloudflare Turnstile. Turnstile processes technical signals to distinguish legitimate submissions from automated abuse. A public site key is shown to the browser; the private secret remains server-side and the returned token is validated with Cloudflare before a message is accepted.
Advertising and Google technologies
SopidoCalc may use Google AdSense or other advertising services in the future. If enabled, Google and its partners may use cookies, local storage, device identifiers or similar technologies to deliver, measure and protect advertising, subject to applicable law and the visitor’s consent choices. Personalized advertising must not be enabled for EEA, UK or Swiss users unless the required Google-certified consent management process is active. Advertising is not required for the calculators to function.
Legal bases and international processing
Where data-protection law requires a legal basis, processing may rely on consent, steps requested by you, legitimate interests such as security and service operation, or legal obligations, as applicable to the situation and jurisdiction. Hosting, security, mail and advertising providers may process information in countries different from yours and may use lawful transfer mechanisms where required.
Retention
Calculator inputs are not stored by default. Contact messages may be retained for as long as reasonably needed to respond, keep necessary business records, resolve disputes or meet legal obligations. Security and rate-limit records should be kept for the shortest practical period consistent with abuse prevention and troubleshooting.
Your choices and requests
Depending on your location, you may have rights to request access, correction, deletion, restriction, objection or portability, or to withdraw consent. Visit Data Request / Deletion for the request process. You can also revisit Privacy & Cookie Choices.
Contact and complaints
Privacy questions can be sent to info@sopidocalc.com. If a privacy law gives you the right to complain to a supervisory or data-protection authority, that right is not limited by this policy.
What this release stores in your browser
| Record | Data and purpose | Duration and control |
|---|---|---|
| Currency reference cache | sopidocalc_fx_v1: followed by a currency pair. Stores the reference rate, rate date and time saved. It does not contain your conversion amount. | A rate is eligible for fallback for seven days. An expired or invalid pair is deleted when a fallback lookup checks it; other records remain until replaced or cleared. Clear cached rates at any time. |
| Optional-feature preference | sopidocalc_consent_v1 records “all” or “essential.” It is not an advertising identifier or a certified consent-management record. | Remains until you change it, clear it in Cookie choices, or remove site data. |
| Optional contact-form session | A PHP session cookie holds an opaque session identifier; server-side session data holds a CSRF token and a one-time submission status. It is used only when the PHP contact service is enabled. | The browser session and the hosting server’s session-expiry settings control its lifetime. Clearing cookies ends your current form session. |
Calculator input fields and generated CSV or PNG files are processed locally. SopidoCalc does not upload exports automatically. Your browser or operating system may retain downloaded files, clipboard contents or restored form state under its own settings.
Currency reference requests
Currency conversion requests a source and destination currency pair from Frankfurter at api.frankfurter.dev. The amount is multiplied locally and is not included in that rate request. Like other network services, the provider can receive the browser’s IP address and ordinary request metadata. A cached fallback is labeled with its date and cache status. Frankfurter service information.
Google advertising data
This release loads no AdSense or Google Analytics tags. If Google advertising is enabled later, Google and other third parties may place or read cookies, use web beacons, collect IP addresses, device identifiers and other information associated with ad delivery, measurement and fraud prevention. Information can also be used for personalization where permitted and consented to. The site will identify active providers and apply the required consent choices before activation.
