Privacy policy
Effective date: July 23, 2026 · Last updated: July 23, 2026
TrimWatt is an independent informational website operated from Switzerland. It is a non-commercial publication: there is no online store, no service sold, no contract concluded on the site, no user accounts, and no forms. This policy describes how the site actually works today.
What we collect today
We do not collect personal data through this website. There is no newsletter form, no sign-up, no account, and no contact form — so there is nothing for you to submit and nothing for us to store. The calculators run entirely in your browser: the values you enter are never transmitted to us and are never saved.
Our hosting provider (Vercel) processes standard technical request data — such as IP address, browser type, and the page requested — to deliver the site and protect it against abuse. We do not use that data to build a profile of you, and we do not combine it with anything else.
Cookies, analytics and advertising
This site sets no cookies of its own, and it currently runs no analytics tool and no advertising programme. The blocks marked “Advertisement” are empty layout placeholders — no ad network is connected and no ad or marketing cookie is served through them.
Fonts and images are served from the site itself, so loading a page does not call a third-party font or media service. If we ever add analytics or advertising, we will name the providers here and update this policy before switching anything on.
Affiliate links
No affiliate programme is active, and there are no affiliate or tracking links anywhere on the site. If that changes, we will say so here and in our affiliate disclosure beforehand.
Your rights
Because we do not collect personal information directly through the website, there is normally nothing for us to access, correct, or delete on your behalf. Limited technical request data may be processed by our hosting provider, Vercel, as described above. If you have a privacy question, you can email privacy@trimwatt.com.
As the site is operated from Switzerland, we aim to act consistently with the Swiss Federal Act on Data Protection; visitors in the EU/EEA retain the mandatory protections available to them under the GDPR. Nothing here removes protections you are entitled to under the law of your own country.
Changes
We will update this policy before activating any newsletter, analytics, advertising, or affiliate service — not after. The effective and last-updated dates above will change when we do.
