Privacy policy
Last updated 29 September 2026.
This policy explains what the OpenCru app for iPhone, iPad and Mac collects, why, who helps us run it, how long we keep it, and how you can see or delete it. The short version: we collect what the app needs to work for you, we don’t track you, we don’t show ads, and we don’t sell anything about you.
What we collect
- Your account. When you sign in with Apple or Google, we receive your name, your email address and an identifier for your account. With Apple you can choose to hide your email; we then get a private relay address from Apple. We never see or keep a password.
- Your photos of labels. The photos you take or upload of a bottle’s front label, back label or the whole bottle.
- Your wines. What you put in the app: the bottles you keep and where (your inventories), whether you tasted them and how it was, who recommended them, your tasting notes, your own notes, and the questions you ask about a wine, such as what to cook with it.
- Technical logs. When the app talks to our servers, the servers log the request (time, address, what was asked, errors) to keep the service secure and fix problems.
We don’t collect your location, your contacts, your photo library beyond the photos you choose, or anything for advertising. The app contains no analytics or tracking tools.
Why we use it
Only to run the app for you: to sign you in, to keep your wines in your account so they’re on all your devices, to read your labels and explain your wines, and to keep the service working and secure. We don’t use your data to profile you, and we don’t share it for anyone’s marketing.
Who helps us run it
- Amazon Web Services hosts our servers, database and your photos, in the European Union (Frankfurt, Germany).
- OpenAI reads the labels in your photos and helps research and explain wines. It receives the photos you take of labels and the wine names and questions involved, through its API, whose terms don’t allow it to use that data to train its models.
- Apple and Google handle signing in, under their own privacy policies.
We don’t sell or rent your personal data to anyone.
The shared catalogue
When your photo reads a wine OpenCru didn’t know, the wine itself — its winery, name, year and region — joins our shared catalogue, so everyone can look it up. That catalogue holds facts about wines, not about you: it doesn’t record who added a wine.
How long we keep it
Your account and everything in it are kept for as long as you have the account. Server logs are deleted after 30 days. When you delete your account, your wines, inventories, tastings, notes, questions and photos are deleted with it, straight away.
Deleting your account
In the app, open Account and choose Delete Account. That’s all it takes. Signing out, by contrast, only removes the sign-in from that device.
Your rights
You can ask us for a copy of your data, to correct it, to delete it, or to stop using it, and you can complain to your data protection authority. Most of this you can do in the app; for anything else, write to us at the address below.
Age
OpenCru is about wine and is meant for adults of legal drinking age where they live.
Changes
If we change this policy, we’ll update the date at the top, and tell you in the app if the change matters.
