Privacy Policy
Sommelier is built to know as little about you as possible. No account, no email address, no advertising and no trackers.
Last updated: 10 August 2026This page in Nederlands · français
1. Who is responsible?
Patrick Leclair, developer of the Sommelier app, Belgium.
Contact: patrick@fast-solutions.group
2. There is no account
You can use Sommelier without registering. We ask for no name, no email address and no telephone number. We do not know who you are.
3. What stays on your device?
Almost everything. The following data is stored solely on your iPhone and is never sent to us:
- your cellar (bottles, vintages, quantities, purchase prices, notes);
- your search history and saved recommendations;
- your tasting notes and ratings;
- your taste profile.
This data is held in the app's secure storage. If you delete the app, it goes with it.
4. What does get sent?
Your request for a recommendation
When you ask for a recommendation, we send the following to our server: the description of your dish or wine, the photo you take of a label or wine list and — if you have enabled this — your taste profile and the relevant bottles from your cellar. Our server immediately forwards this to Anthropic, which carries out the analysis, and returns the answer to you.
We do not retain the content of your requests or your photos. They pass through our server only in order to be forwarded. Anthropic retains API inputs and outputs for a maximum of 7 days in order to detect misuse, and does not use them to train AI models.
Please do not take photos showing people or other private information: photograph only the label or the wine list.
An anonymous device number
On first launch, the app generates a random number. This is not an Apple ID and not an advertising identifier, and it cannot be traced back to you. We use it solely to count how many free recommendations you have left, to enforce the daily fair-use limit and to check your subscription status. If you delete the app, the number is gone; on a fresh installation you receive a new one.
Your subscription
Purchases are handled entirely through the App Store. We never see your payment details. To establish whether you have Premium, we exchange only the anonymous device number and your status ("active or not") with RevenueCat.
5. What we do not do
- No advertising and no ad networks.
- No third-party analytics or tracking software.
- No sale or rental of data to anyone.
- No building of profiles about you outside the app.
6. Legal basis (GDPR)
| Purpose | Legal basis |
|---|---|
| Providing the wine recommendation you request | Performance of the contract — Art. 6(1)(b) GDPR |
| Counting the free quota and the fair-use limit | Legitimate interest: preventing misuse and runaway costs — Art. 6(1)(f) GDPR |
| Checking subscription status | Performance of the contract — Art. 6(1)(b) GDPR |
7. Who else processes data on our behalf?
| Party | Role | Location |
|---|---|---|
| Cloudflare, Inc. | Our server and counters | Global network, edge processing (including the EU) |
| Anthropic PBC | AI analysis of your request | United States |
| RevenueCat, Inc. | Subscription status | United States |
| Apple Inc. | Distribution and payments | Ireland / United States |
For transfers outside the European Economic Area, we rely on the data processing agreements and the European Commission's Standard Contractual Clauses used by these suppliers.
8. How long do we keep anything?
| Data | Retention period |
|---|---|
| Content of your requests and photos | We do not retain it; a maximum of 7 days at Anthropic |
| Counter for your daily limit | 25 hours, then automatically erased |
| Counter for your monthly free recommendations | For as long as you use the app, and no more than 12 months after you last used it |
| Data within the app itself | Until you delete it or delete the app |
9. Your rights
You have the right of access, rectification, erasure, restriction of processing, objection and data portability. Because we keep no account, we cannot identify you by your name or email address — do write to us and we will explain what is possible in your case.
The quickest way to erase everything relating to you is to delete the app from your device. Doing so removes your local data and your anonymous device number, and leaves the counters on our server no longer linked to anything.
If you are unhappy with how we handle your data, you may lodge a complaint with the Belgian Data Protection Authority, Rue de la Presse 35, 1000 Brussels — dataprotectionauthority.be.
10. Recommendations generated by artificial intelligence
The wine recommendations in Sommelier are generated by an AI model, not by a human sommelier. Like any AI system, it can get things wrong: please verify important information yourself, particularly before making a purchase. Sommelier offers advice on taste, not medical or nutritional advice.
11. Age
Sommelier is about wine and is not intended for minors. We do not knowingly collect data from children.
12. Changes
Whenever this policy changes, we update the date at the top. In the event of a substantial change, we will notify you in the app.
