Mestor

Privacy notice

Last updated: 8 November 2026

Draft: the text has yet to be reviewed by a lawyer.

Mestor is built to work on your device: the colour and image calculations run in your browser. Here is what happens to data, in plain words.

Who the controller is

Data controller: Ivan Antonino Pace, e-mail nk1530htu@mozmail.com.

What stays on your device

Reference images and photos of the paste are processed in the browser and are not uploaded to any server.

Your preferences (language, medium, chosen tubes, calibrated tubes) are saved in your browser’s local storage (localStorage) on your device. They are not sent to us. You can delete them at any time by clearing the site’s data in your browser settings. This is technical storage, needed to provide the features you ask for, so it does not require consent (Art. 5(3) of the ePrivacy Directive, Art. 122 of the Italian Privacy Code).

Cookies and analytics

Mestor uses no cookies, no analytics and no advertising or profiling tools. The fonts are hosted on our own site: your browser does not contact third-party services to load them.

Website hosting

The site is hosted by Cloudflare, Inc. (Cloudflare Workers). To deliver the pages and protect them from abuse, Cloudflare processes technical data such as your IP address, browser type and the time of the request, as a processor. The legal basis is our legitimate interest in running the service securely (Art. 6(1)(f) GDPR). Cloudflare may process these data outside the European Union, with the safeguards the GDPR requires; retention and details are in Cloudflare’s privacy policy (cloudflare.com/privacypolicy). We do not turn on Cloudflare visit logs or analytics.

Voice commands

In easel mode you can choose to turn on voice commands. They use your browser’s speech recognition: depending on the browser (Chrome, for example), the audio may be sent to the browser vendor’s servers and handled under its terms. Mestor does not receive the audio. The browser asks for permission to use the microphone, and you can withdraw it at any time.

Reading recipes aloud uses your device’s speech synthesis.

Accounts, payments and online saving

There are no accounts, payments or online saving today. When they arrive (with the Pro plan), this notice will be updated before they go live, stating the data processed, the providers involved and the retention periods.

If you write to us

If you e-mail us, we use your address and your message only to reply, and keep them as long as needed to handle the request.

Automated decisions

We make no automated decisions about you and do no profiling. Recipes are colour calculations that run on your device.

Your rights

You have the right to request access, rectification, erasure, restriction and portability of your data, and to object to processing, by writing to the address above. You also have the right to lodge a complaint with the Italian data protection authority (Garante per la protezione dei dati personali, garanteprivacy.it) or with the authority of the country where you live.

Children

The service is not directed at children under 14.

Changes

If we change this notice, we update the date at the top. Significant changes are announced on the site.
