Legal Notice

Service and contact

Opti-LZ Labs is a beta web application available at optilz.com. General, privacy, correction, copyright, trademark, restaurant-data, and complaint requests can be sent to optilz.support@gmail.com.

Beta and commercial status

Real-money purchasing is currently unavailable and blocked by the server. The current release does not claim trademark registration, professional legal clearance, regulatory approval, medical-device status, or endorsement by any restaurant or platform provider.

Verified operator identity, geographic address, company or trade-register information, tax information, competent authority details, and any legally required dispute-resolution disclosures have not yet been provided for publication. They must be completed and professionally reviewed before commercial launch or activation of paid purchasing. No missing value has been invented on this page.

Third-party identification

Apple, Google, Stripe, restaurant, grocery, and product names are used only where needed to describe compatibility, sources, or factual listings. Unless expressly stated with verified evidence, Opti-LZ Labs is not an official partner of those organizations.

Opti-LZ Labs Calculator uses locally bundled open-source MathLive, CortexJS Compute Engine, Math.js, Function Plot, and their compatible dependencies under the licences identified in Third-Party Notices. Guided formulas and local data-analysis routines are implemented in Opti-LZ Labs code without a paid computation service. Optional currency facts are attributed to the European Central Bank. No third-party calculator design or commercial calculator source code is copied.

Policies

Read the Privacy Policy and Terms of Service for the implemented data, health, calendar, location, restaurant, purchase, refund, export, and deletion behavior.
