Privacy Policy
Worth Opening: WSET Level 3 (WSET L3 Mocks on your home screen)
Last updated: 26 September 2026
The short version
The app has no account and no sign-in. Your study data stays on your phone. We do not collect, store or transmit your personal data. There are no adverts, no tracking, and nothing that watches how you use the app. The one exception is a purchase, which is described under Purchases below.
What stays on your phone
All of the following is written to your device's local storage and never leaves it:
- Your answers, marks and results for every mock and practice run
- Which questions you got wrong, your bookmarks, and your drill scores
- Your flashcard progress and when each card is next due
- Your exam date and your daily reminder time
- Any photo you attach to a tasting note
- Your language choice and app settings
None of this reaches Worth Opening or anyone else. We cannot see it, recover it or restore it. Deleting the app deletes all of it permanently.
Photos
You can attach a photo of the bottle or the glass to a tasting note. When you do, the app asks your phone for permission to use the camera or your photo library, and copies the picture you choose into its own storage on the device.
That copy never leaves your phone. It is not uploaded, not backed up by us and not readable by us. Removing the photo in the app, or deleting the app, removes it.
Result cards
You can share a card of a mock result: the paper, your scores and the date, nothing else. The app draws the card on your phone and hands the picture to your phone's own share sheet. Where it goes from there is your choice, and nothing is sent to us. If you save the card to your photos, your phone asks your permission to add it; the app does not read your photo library to do so.
Reminders
If you turn on the daily reminder, the app schedules a notification on your phone at the hour you pick. It is handled entirely by the phone. There is no push server, no notification token and nothing sent over the network. Turning the reminder off cancels it.
What we do not do
- No account, no email address, no name, no password
- No analytics on how you use the app, no usage tracking, no crash reporting
- No advertising and no advertising identifiers
- No location data
- No access to your contacts, microphone or location
- No access to your photos beyond the single picture you choose to attach, and a result card you choose to save
- No selling or sharing of data, because we hold none to sell or share
Purchases
Mock 1 is free. Mocks 2 to 20 are unlocked by a single one-off payment.
That payment is handled entirely by Apple's App Store or Google Play. We never see your card details, billing address or any other payment information.
To check whether you have paid, and to let you restore your purchase on a new phone, the app uses RevenueCat, a purchase-management service. RevenueCat receives:
- A randomly generated identifier for your app installation, which is not linked to your name or email
- The purchase receipt issued by Apple or Google
- Your country and device platform, as supplied by the store
RevenueCat does not receive your exam answers, results or any study data.
We use RevenueCat's dashboard to see how many unlocks have been bought and in which countries. Apple's privacy questionnaire calls that analytics, so the app's App Store privacy label says so. It is counting sales, not watching you, and nothing in it identifies you. Its privacy policy is at revenuecat.com/privacy.
Apple and Google handle their own data under their own privacy policies.
Links out of the app
The Settings screen links to worthopening.wine and can open your email app to contact us. Following a link takes you out of the app and onto the ordinary web, where the destination site's own privacy policy applies.
Children
The app refers to alcohol throughout and carries the age rating the App Store and Google Play give that content. It is made for people studying for a wine qualification and is not directed at children. We do not knowingly collect data from anyone.
Your rights
Because we hold no personal data about you, there is nothing for us to give you a copy of, correct or delete. If you want the data the app holds gone, use "Reset all progress" in Settings, or delete the app.
If you have bought the unlock and want your RevenueCat record deleted, email us and we will ask RevenueCat to remove it. Note that deleting it means you will no longer be able to restore your purchase.
Changes
If this policy changes we will update this page and the date at the top. Material changes will also appear in the app's release notes.
