Privacy Policy

Version 1.2 · effective 26 October 2026

Privacy at a glance

Origin Labs s.r.o., Company ID No. (IČO) 28204352, registered office Wichterlova 2372/8, Libeň, 182 00 Praha 8, Czech Republic, operates and publishes Nutrinaut Tools. Privacy questions and rights requests can be sent to [email protected].

Calculator inputs are processed inside your browser and are not submitted to the Nutrinaut Tools application server. We use no calculator account, database, paid AI API, analytics service, error-tracking script or embedded social-media content in this version.

Local device data

Optional preferences and recipe worksheets

The “Privacy & cookie settings” dialog may store the value nutrinaut_privacy_notice_v1 in localStorage when you choose “Save & close.” It records only that the notice was acknowledged. Clear it in the same dialog or with your browser’s site-data controls.

Recipe Yield / Grocery saves one input worksheet in localStorage under nutrinaut.recipe-workspace.v1 only when you choose “Save in this browser.” It can contain ingredient names, amounts, nutrition values, finished yield, portion size, pantry amounts, packaging, prices, assumptions and example labels. Calculated results are not saved in that JSON worksheet. Later edits are not saved automatically, and nothing is uploaded to an account or server.

“Restore saved copy” reads those inputs only when requested and clears any old result; calculate again after restoring. “Clear worksheet & saved copy” clears the open worksheet and removes that saved key. Browser site-data controls can also remove it. This is not an account backup or storage encrypted by this tool; someone with access to the same browser profile may be able to read it. Use a private device for private values. Clearing browser data can remove the saved copy.

JSON imports are read locally, not uploaded. Exported worksheet JSON contains entered values and example labels; a TXT receipt or copied checklist can also contain results and assumptions. Downloads and clipboard copies happen only when you request them. They can contain private values: share them only when you intend to share those values. Clearing the worksheet does not delete files already downloaded or copies outside this page.

Infrastructure

Operational request data

The hosting and CDN layer receives an IP address and request data to deliver and secure a page. Operational or security logs may include IP address, time, requested path, response status, user-agent, referrer and security events. The application does not create its own visitor-log database or use these records for advertising profiles.

Infrastructure records are handled under the providers’ configured security and retention settings and may be processed outside your country with appropriate safeguards. Origin Labs limits access to people who need it for security, availability or incident investigation.

Contact

Email you choose to send

The site offers a public email link, not a web form. Your email provider and Origin Labs’ provider process the address, subject and message you send. We use it to answer the request and retain the conversation only as long as needed for follow-up, legal obligations and a reasonable record of corrections or privacy requests. Please do not send sensitive health information.

Third-party advertising

Current status

Nutrinaut Tools currently does not load third-party advertising scripts or set advertising cookies.

If Google AdSense is enabled after approval, third-party vendors including Google may place or read cookies or use similar technologies to serve and measure ads, including ads informed by prior visits where permitted. Before that change, this policy will identify the enabled providers and purposes, link to Google Ads Settings and Google’s partner-sites explanation, and provide any additional vendor choices.

For visitors in the EEA, United Kingdom and Switzerland, advertising will not be enabled until a Google-certified consent management platform is in place where required. The permanent privacy settings control will then let visitors consent, decline, manage or withdraw the relevant choices.

Calculator inputs and health or fitness information are not used to select personalised ads or create advertising audiences.

Your choices and rights

Access, correction, deletion and objection

Depending on where you live, you may have rights to access, correct, delete, restrict or object to processing, and to receive portable data. Because calculator inputs never reach us, we cannot retrieve them. For email or operational-data questions, contact us using the address above. You may also complain to your local data-protection authority.

The site is intended for adults and is not designed to collect children’s personal information. Reasonable technical and organisational measures protect the limited data in scope, but no internet transmission is risk-free.
