No account is required to play. We don't sell your data. Non-premium players see ads served by Google AdMob; Express Pass removes them entirely. If you create an account your email is stored so you can sync progress across devices — that's the only personal data we ever hold.
Short version
Trainyard Daily is built by Multicode Ltd., a small studio in Yorkshire, UK. We are the data controller for everything described below. We aim to be GDPR-compliant by default, not just because we have to.
What we collect
On your device, the app stores: your solved-puzzle history, your in-progress tracks, your settings (sound, haptics, theme), and a randomly-generated anonymous device ID used to save your progress without requiring an account.
If you create an account (optional), we store your email address and a hashed password so your progress can sync across devices and your streak is protected.
If you purchase Express Pass, your purchase is processed by RevenueCat and Google Play. We receive a confirmation of entitlement but never see your payment card details.
If you contact support, we receive whatever you put in your message — name, email, attachments — held only in our support inbox.
We do not collect: contacts, location, photos, microphone, camera, or biometric data.
How we use it
Your anonymous device ID and gameplay data are used to save your puzzle progress and streaks. If you have an account, your email is used solely for login and account recovery — we don't send marketing email.
Aggregate, anonymised stats (how many people solved today's puzzle, average solve time) help us calibrate difficulty. None of this is tied to a real-world identity.
Non-premium users see personalised ads served by Google AdMob. Purchasing Express Pass removes all ads.
Third parties
We use the following third-party services:
- Google Play — distributes the app and handles payment processing. Subject to Google's privacy policy.
- RevenueCat — manages in-app purchase entitlements (Express Pass). They receive purchase confirmation from Google Play. Subject to RevenueCat's privacy policy.
- Google AdMob — serves ads to non-premium users. AdMob may collect advertising identifiers and usage data per Google's privacy policy. Purchasing Express Pass opts you out of all ad tracking.
- Help Scout — our support inbox. Support emails are held for as long as the conversation is open, then archived for 24 months.
We do not use analytics platforms, session recorders, or any other third-party tracking tools.
Retention
Anonymous device data: retained until you uninstall the app or request deletion. Account data: retained until you request account deletion. Support emails: 24 months from last reply, then deleted. Aggregate gameplay stats: indefinitely, since they contain no personal data.
Your rights
Under UK and EU GDPR you have the right to access, correct, or delete personal data we
hold about you. Email
You can also complain to the UK Information Commissioner's Office (ICO) at ico.org.uk at any time.
