1. Scope
This Privacy Policy explains how Coderic Technologies (“Coderic Technologies”, “we”, “us”, or “our”) handles information when you use the Calculas mobile application (the “App”), its calculator and conversion tools, and links opened from the App.
2. Information we collect
Calculas does not require registration and does not intentionally collect your name, email address, contacts, photos, precise location, microphone recordings, camera data, payment information, or account credentials.
| Information or activity | How it is handled |
|---|---|
| Calculator inputs and results | Processed on your device. They are not sent to Coderic Technologies. |
| Converter inputs and results | Processed on your device for standard unit conversions. |
| Conversion history and favourites | Used to show history and favourites inside the App. The current implementation keeps this information in local app memory and does not send it to our servers. |
| Currency conversion request | When currency rates are refreshed, the App requests public exchange-rate data from open.er-api.com. The request contains currency/rate information, not your calculator history or personal profile. |
| Technical information | We do not operate analytics, advertising, crash-reporting, or user-profiling services in the current version of Calculas. The exchange-rate provider or your network/operator may process technical data such as an IP address as part of ordinary internet communication. |
3. How we use information
We use information only to:
- perform calculations and unit conversions;
- display your recent conversion history and favourites locally;
- retrieve current currency rates when you use the currency converter;
- open the Coderic Technologies and Coderic Studio websites when you choose a website link; and
- respond to privacy or support requests that you voluntarily send to us.
4. Sharing and third-party services
We do not sell, rent, or share your calculator inputs, conversion history, or favourites with advertisers or data brokers.
The currency converter can contact the following third-party endpoint to obtain exchange rates:
Endpoint: open.er-api.com
Purpose: currency exchange-rate data
Data sent by Calculas: the rate request; no account, calculator history, or personal profile is intentionally included.
Third-party services may process technical data under their own privacy policies. You should review the applicable third-party terms before using live currency rates. If the request fails, Calculas can use fallback rates bundled with the App.
5. Website links
Calculas may open these websites when you tap a link:
Those websites are operated separately and may have their own privacy policies, cookies, analytics, or contact forms. This policy does not govern information you submit directly on those websites.
6. Local storage, retention, and deletion
Calculas does not currently maintain a cloud account or central database for your calculations. Local history and favourites remain available according to the App’s local storage lifecycle and can be deleted using the App’s controls or by clearing the App’s data/uninstalling the App through your device settings.
Information you send to us by email or through a website contact form is retained only as long as reasonably necessary to respond, provide support, resolve disputes, and meet applicable legal obligations.
7. Security
We use reasonable technical and organisational measures appropriate to the App’s limited data practices. No internet transmission or electronic storage method can be guaranteed to be completely secure. Because standard calculations and histories are processed locally, they are protected primarily by the security of your device and operating system.
8. Children’s privacy
Calculas is a general-purpose utility and is not directed at children under 13 (or the minimum age required in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us so we can investigate and delete it where appropriate.
9. Your rights and choices
Depending on where you live, you may have rights to request access to, correction of, deletion of, or information about personal data you have voluntarily sent to us. You can also stop currency-rate requests by not using the currency converter or by disabling the App’s network access through your device controls. To make a privacy request, contact us using the website links below.
10. International use
If you use live currency rates, your request may be routed through networks or service providers located in countries other than your own. The App itself does not create a user account or transfer your local calculator history to us.
11. Changes to this policy
We may update this Privacy Policy when the App’s features, third-party services, or legal requirements change. We will update the effective date above and publish the revised version at the location where this policy is made available. Your continued use of the App after an update means the updated policy applies to your use going forward.
