Privacy policy

Last updated: 3 November 2026

BedtimeKnowledge is designed to need as little data as possible. You never create an account, and the app never asks for your name, email or contacts.

What the app stores on your phone

• Your settings (evening time, reminder on/off, language) and your quiz results, used for your score and streak.
• Your reminder is a local notification scheduled by your phone. We don’t use push notifications or push tokens.

What reaches our servers

• An anonymous ID, created automatically the first time you open the app. It is not linked to your name, email or Apple ID.
• Quiz results: the issue number, which answers were right, your score and when you played.
• A backup of your progress (quiz results, the facts you’ve learned, your evening time, reminder and language), so you get it back after reinstalling the app or on a new phone. To find your anonymous account again, the app keeps a sign-in key in your iPhone’s Keychain; it contains no personal data.
• Reports and feedback you choose to send, such as “report a problem with this fact”: the text you write and the fact it is about. Also the 😂 / 🤯 / 😐 reactions you tap on facts. Quiz scores are only ever shown to others as totals (“you beat 64% of readers”), never one by one.
• Usage statistics, such as “opened tonight’s issue”, “finished the quiz” or “tapped share”, with basic device information (device model, iOS version, app version, language). We use them to understand which features work and to improve the app.
• Crash reports: if the app crashes or hits an error, a technical report (what went wrong, app version, device model, iOS version). It contains no name, email or IP address, and no recording of your screen.

We don’t show ads, we don’t track you across other apps or websites, and we never sell or share your data for advertising.

Website waitlist

If you join the beta waitlist on this website, we store your email address only to send you the beta invitation and launch news. You can ask us to delete it at any time.

Who processes the data

• Supabase: database hosting for the anonymous ID, quiz results, reports and the waitlist.
• PostHog (EU servers): usage statistics.
• Sentry (EU servers): crash reports.
• Apple: app distribution (App Store, TestFlight) and, if you agree to share them with developers, crash reports.

How long we keep it

Data linked to an anonymous ID is kept while the app is in use and deleted on request. Usage statistics are kept for up to 2 years. Waitlist emails are deleted when you ask, or one year after launch.

Your rights

Delete your data yourself, at any time: in the app, Settings → Delete my data. It removes your quiz results, reactions, reports and feedback from our servers, and your progress and settings from your phone.

Under UK and EU data protection law (GDPR) you can also ask to access, correct or delete your data, or object to its use. Because the app is anonymous, include the anonymous ID shown in the app (Settings) so we can find your data, or the email address you used for the waitlist.

Children

BedtimeKnowledge is not directed at children under 13 and we don’t knowingly collect their data.
