Last updated 27 August 2026
M33 Station: Calm & Sleep ("the App") is provided by Messier 33 Entertainment Limited ("we," "us," "our"), a company registered in England and Wales, Brentford, United Kingdom. This policy explains what information we collect when you use the App, why we collect it, and the choices you have.
Questions about this policy or your data? Write to m33ent@gmail.com.
01
Information we collect
We collect the minimum needed to run your account and process subscriptions. We do not collect analytics, advertising identifiers, or behavioural data, and we do not use tracking technologies for advertising.
Account information
- •Your email address, used to create and secure your account
- •Your name, only if you choose to share it via Sign in with Apple
- •A unique account identifier generated by our authentication provider (Supabase)
Subscription information
If you subscribe to M33 Station Pro, our subscription platform (RevenueCat) and Apple's or Google's billing systems record your subscription status so the App can unlock what you've paid for. We never see or store your card details, that's handled entirely by Apple or Google.
What we don't collect
Location, contacts, photos, health or fitness data, microphone or camera input, browsing history, or any record of what you listen to or when. No analytics, crash-reporting, or advertising SDKs are integrated into the App.
02
How we use it
Strictly to authenticate you, keep your subscription status correct, and provide support if you contact us. Never for advertising, marketing, profiling, or content personalisation.
03
Third-party services
Each of the following processes only the data its function requires:
- •Supabase — authentication and account storage
- •RevenueCat — subscription and entitlement management
- •Apple App Store / Google Play — subscription billing
- •Cloudflare — audio delivery, via short-lived, non-identifying access tokens
We do not sell your information, and we do not share it with data brokers or advertising networks.
04
Retention & deletion
We keep your account information for as long as your account is active.
- •You can permanently delete your account at any time in the App: open the home screen and tap Delete account, next to Sign out. This is immediate and permanent, not a deactivation, and it cannot be undone.
- •If you delete your account while a subscription is active, cancel it separately in your Apple or Google account settings, since billing is managed there directly.
05
Your rights
Depending on where you live, you may have rights to access, correct, or delete your personal data, and to object to or restrict certain processing, including under UK GDPR and the EU GDPR. Exercise these by deleting your account in the App (Section 4) or by writing to m33ent@gmail.com.
06
Children's privacy
Some playlists are designed to be played for babies and young children by a parent or guardian, but the App itself is operated by an adult, account creation requires signing in via Apple, Google, or email. We do not knowingly collect personal information directly from children. If you believe a child has provided us information without appropriate parental consent, contact m33ent@gmail.com and we will delete it.
07
International transfers
Our service providers may process data outside the UK or your country of residence, including in the United States. Where this happens, we rely on the safeguards required by applicable data protection law.
08
Changes to this policy
We may update this policy from time to time. Material changes will be reflected in the "Last updated" date above. Continuing to use the App after changes take effect means you accept the updated policy.
