Privacy Policy
Vintage IQ is a wine vintage chart. It does not ask you to create an account, it does not collect personal information, and it does not show ads. This page explains exactly what the app and this website do with data.
1. Who this policy covers
This policy applies to the Vintage IQ mobile app for iOS and Android (the "App") and to this website at vintage-iq.web.app (the "Site"). Together they are the "Service". "We", "us" and "our" refer to the publisher of Vintage IQ.
2. What the App collects
The App collects no personal data. Specifically, the App does not:
- require or offer user accounts, sign-in, or registration;
- ask for your name, email address, phone number, location, contacts, photos, or any other personal information;
- include advertising, advertising identifiers, or ad networks;
- include analytics, crash-reporting, or tracking SDKs;
- sell, rent, or share any information about you with third parties.
3. Network requests the App makes
To show you a live chart, the App fetches two things over the internet:
- Chart data from a published Google Sheet (hosted by Google), downloaded as a plain CSV file.
- App configuration from a single public document in Google Cloud Firestore (part of Google Firebase), which tells the App where the chart lives and whether it is temporarily in maintenance.
These are ordinary, anonymous HTTPS requests. As with any internet request, Google's servers receive your device's IP address and standard request headers in order to respond. We do not attach any identifier to these requests and we cannot see who made them. Google's handling of such requests is governed by the Google Privacy Policy.
4. Data stored on your device
The App keeps a small amount of information on your phone only, so that it works offline and remembers your preferences:
- a cached copy of the most recently synced chart and configuration;
- your appearance preference (System, Light, or Dark).
This data never leaves your device. Deleting the App removes it.
5. What the Site collects
This Site uses Google Analytics for Firebase to understand how many people visit and which pages they view. This is standard, aggregated web analytics. It may set cookies or use similar technologies and collects information such as your approximate location (derived from IP address), device and browser type, pages viewed, and referring site. Google Analytics is configured with IP anonymisation where available, and we do not use it to identify individual visitors.
You can opt out of Google Analytics across all websites with the Google Analytics opt-out browser add-on, or by blocking cookies in your browser. The Site works fully without analytics.
The Site is hosted on Firebase Hosting, which, like any web host, keeps short-lived server logs (including IP addresses) for security and operational purposes.
6. Children
Vintage IQ is about wine and is intended for adults of legal drinking age in their country. It is not directed at children, and we do not knowingly collect any information from anyone under 18. Because the App collects no personal data at all, there is nothing for us to delete; if you believe a child has used the Site and left analytics data, contact us and we will help.
7. Your rights
Depending on where you live, you may have rights under laws such as the GDPR (European Union and United Kingdom) or the CCPA (California) to access, correct, delete, or restrict personal data about you. Because the App holds no personal data about you, and the Site holds only aggregated analytics, there is usually nothing to act on. You are nonetheless welcome to contact us with any request, and we will respond within 30 days.
8. Security
All network traffic between the App, the Site and their data sources uses HTTPS. The data sources themselves are read-only to the public and cannot be modified from the App.
9. Changes to this policy
If we change the way the Service handles data, we will update this page and the effective date at the top. Material changes, such as adding analytics to the App, will be called out clearly here and in the App's release notes.
