Privacy Policy
We designed OneCalc so your files and calculations stay on your device.
1. Information we collect
OneCalc does not require an account. We do not collect names, email addresses or payment details unless you voluntarily contact us.
Basic, aggregated usage analytics (page views, device type, approximate region) may be collected to improve the service.
2. Your files
Image, document, audio, video, archive, QR and OCR conversions run entirely in your browser. Files are never uploaded to our servers and are discarded from memory when you leave the page.
3. Local storage
Preferences such as theme, favourites and recent conversions are stored in your browser's local storage. You can clear them at any time from your browser settings.
4. Third-party services
Live currency rates are fetched from a public exchange-rate API. Fonts may be served from a public CDN. These providers may log standard request metadata such as IP address.
5. Cookies
OneCalc does not use advertising or tracking cookies. Any cookies present are strictly functional.
6. Your rights
Because we hold virtually no personal data, there is generally nothing to export or delete. If you have contacted us by email, you may request deletion of that correspondence at any time.
7. Contact
Questions about this policy, or requests to access or delete any data associated with you, can be sent to onecalcapp@gmail.com. We respond to privacy requests within 30 days.
