Privacy policy
Last updated 1 October 2026
Quizling is a pub quiz app you play together on one phone. This policy explains what we collect, why, who helps us run the app, and your rights. "We" means Quizling, based in the United Kingdom. Questions: hello@quizling.co.uk.
The short version
- You can play without an account.
- No ads, no tracking across other apps or websites, and we never sell your data.
- You can switch off usage stats, and delete your profile and its data at any time in the app.
What we collect
| What | When | Why |
|---|---|---|
| An anonymous ID | First time you open the app | So your saved players, quizzes and games belong to you, even without an account. |
| Email address | If you create a profile (by emailed code or Sign in with Apple, which may give us a private relay address) | To sign you in and keep your profile on any phone. |
| @handle, display name and avatar | If you create a profile | So friends can find and link you, and your quizzes show who made them. |
| Profile photo | Only if you choose to add one | Shown instead of your emoji to you and to friends you've linked with. You can remove it at any time. |
| Players you add | When you type names into "Who's playing?" | So you don't have to type them again. They sync between your phones. |
| Games and scores | When you play | Pack stats and difficulty ratings, and scores for players linked to an account. |
| Quizzes you make | When you use "Make a quiz" | To write and keep your quiz, and to avoid repeating questions you've had in the past year. |
| Reports | When you report a question or quiz | To fix mistakes and remove anything unsuitable. |
| Notification token | If you allow notifications | To tell you about new packs, offers and friend requests. |
| Quizling Gold status | If you subscribe | We check your subscription with Apple or Google so Gold works on your account. We never see your payment details. |
| Usage stats | Unless you switch off "Help improve Quizling" in Profile | Which screens and features are used, so we know what to improve. Deleted after 90 days. |
| Show on phones | When a host shows a quiz on other phones | The current question and whose turn it is, shared with anyone who has the code. Deleted within hours of the quiz ending. |
We don't collect your location, contacts, or anything about your use of other apps. We only see a photo if you choose one for your profile, and we remove its location and other hidden details first.
What other people can see
- Your @handle and avatar can be looked up by someone who types your exact handle, for example to link you as a player. There's no public list of members.
- Quizzes you share can be opened by anyone with the code or link, with your @handle shown as the maker. Stop sharing at any time.
- Linked players: if you accept a link request, the host's games record your scores against your account, and the host sees your handle. You can unlink at any time.
Who helps us run Quizling
These companies process data for us, only to provide their service:
- Supabase: database, sign-in and storage (hosted in London).
- Anthropic: writes quizzes from the theme you type, and checks profile photos are suitable before anyone else sees them. We send the theme and, to avoid repeats, questions you've had before, or the photo. Anthropic doesn't use this to train its models.
- Expo: delivers notifications and app updates.
- Apple and Google: app stores, purchases, Sign in with Apple and notifications.
- Google Firebase: older versions of the app, while people update.
- Netlify: hosts this website.
- Our email provider: sends sign-in codes and handles email to us.
Some of these are in the United States. Where data leaves the UK, it's protected by the UK's approved safeguards, such as the International Data Transfer Addendum.
Why we're allowed to use it
- To provide the app you asked for (your profile, quizzes, games and Gold): performing our agreement with you.
- Usage stats, security and preventing abuse: our legitimate interest in running and improving Quizling. You can switch usage stats off.
- Notifications: your permission, which you can withdraw in your phone's settings.
How long we keep it
- Your profile and quizzes: until you delete your profile.
- Usage stats: 90 days.
- Show on phones: removed within hours of the quiz ending, and never more than 3 days.
- Records we must keep for security or accounting (for example AI costs or moderation decisions) are kept without your name or ID once you delete your profile.
Your rights
You can see, correct, download or delete your data, and object to how we use it. Delete everything yourself in the app: Profile › Delete profile. For anything else, email hello@quizling.co.uk and we'll reply within a month. If you're unhappy with how we've handled your data, you can complain to the Information Commissioner's Office at ico.org.uk.
Children
Quizling is for everyone to play together, but profiles are for people aged 13 and over. If you think a child under 13 has made a profile, tell us and we'll delete it.
Changes
If we change this policy we'll update the date at the top, and tell you in the app if the change matters.
