Marketplace Waitlist

If you join the waitlist for our upcoming marketplace, we store your email address, country and ZIP code, the time you joined and the wording you agreed to. We use them only to tell you when the marketplace opens in your area.

You enter the email address yourself, and we send it a link to confirm it. You are added only after you confirm, and submitting the address is your agreement to this policy.
The legal basis is your consent (Art. 6(1)(a) GDPR). You can withdraw it at any time by writing to isitgold@marvinbuth.dev, and we will delete your entry.
We keep your entry until we have told you that the marketplace is open in your area, or until you withdraw your consent.

Website Language

Our website, isit.gold, is available in the same languages as the app.

Country lookup: On your first visit, our hosting provider (Vercel) tells the website which country your connection comes from, based on your IP address. Together with the languages your browser says you prefer, we use it once to suggest a language. We do not store or log it.
Language cookie: When you choose a language, in the dialog on your first visit or with the language switch, the website stores a cookie named NEXT_LOCALE. It contains only the code of the language you chose (for example "de"), is used only to show you the website in that language on later visits, and expires after one year. It is set only when you choose a language. You can change it at any time with the language switch, or delete it in your browser settings.
The cookie is strictly necessary to give you the language you asked for, so it does not require consent (§ 25(2) no. 2 TDDDG). The legal basis for the country lookup is our legitimate interest in showing you the website in a language you understand (Art. 6(1)(f) GDPR).

When you use our web app at app.isit.gold, including the free Value Checker, a banner asks whether we may measure how the page is used. Accept and Decline look the same, and the web app works the same with either choice.

Before you choose, and if you decline: we do not use Google Analytics or Google Ads measurement. Nothing is sent to Google measurement services and no measurement cookies are set.
If you accept: the web app uses Google Analytics (Firebase) and Google Ads to see how visitors use IsItGOLD? and which ad brought them here. Google sets cookies on your device (such as _ga and _gcl_au) and receives usage data: the steps you take in the Value Checker (for example opening the page, adding a photo, a finished or failed check, creating an account, signing up for the newsletter or the marketplace waitlist, opening the app), the result of your check (verdict, metal and confidence), the ID of your check, your user ID in our app (a random ID that guests have too), the country you choose for the marketplace waitlist, the campaign parameters of the link you came from (utm_source, utm_medium, utm_campaign, utm_content), the platform, and the technical data every request to Google carries, such as your IP address and browser details. We do not send your email address, name, photo or ZIP code to Google for this.
Google Consent Mode: all four signals (analytics storage, ad storage, ad user data and ad personalization) are denied until you accept, and denied again when you withdraw.
Your choice: it is stored in your browser, only on this device, with the time and the version of the banner text. You can change it at any time with Cookie settings on the start page of the Value Checker, in its account step or under Profile > Legal, which shows the banner again and stops the measurement. Clearing the site data of your browser also resets it.
Legal basis: your consent (§ 25(1) TDDDG and Art. 6(1)(a) GDPR). Withdrawing it does not affect what was processed before.
Campaign parameters on our servers: if you open the Value Checker through one of our ads, the parameters of the link (utm_source, utm_medium, utm_campaign, utm_content, utm_term, ref), the page you landed on and the website you came from are also saved with your check and, if you create an account, with your account, so that we can tell which ad led to it. This does not depend on the banner.
The mobile apps are described in the sections above.

Your Rights

Depending on your jurisdiction, you may have rights to access, correct, restrict, or delete your data. You may also:

Opt out of personalized ads by adjusting your device settings (Google/Android: Settings > Google > Ads > Opt out of Ads Personalization, iOS: Settings > Privacy > Tracking).
