Privacy Policy
Last updated: November 8, 2026
This policy explains what information Chainiac (“we”, “us”, “our”) may collect when you use the Chainiac app or website (together, the “Service”), how we use it, and the choices you have. The Service is in beta, so this policy describes what we collect or may collect as it develops.
The short version: we collect only what we need to run the Service and your account, we do not sell your information, and we do not use it for advertising.
Information we may collect
Information you give us.
- Account details: your email address and password, or the name and email address that Apple shares if you choose to sign in with Apple. Passwords are handled by our authentication provider and are not stored in readable form.
- A display name, which we set from your email address until you change it.
- Messages you send us, and the information in them.
Information created when you use the Service.
- Activity and results within the app, such as your progress, scores, times and settings.
- Subscription status, if you buy a paid plan: whether you have one, and when it started and renews. Payments are handled by Apple or Google. We never receive your card number or billing address.
Technical information. Our servers and hosting providers receive standard request data, such as your IP address, your app or browser version and the time of each request. We use it to deliver the Service, limit abuse and keep it reliable.
Stored on your device. The app keeps some information on your device, such as your progress and settings. On the website this uses your browser’s local storage. It leaves your device only if you create an account and syncing is available.
What we do not collect. We do not ask for your location, contacts, photos, microphone or camera. We do not run advertising or third-party analytics tools at this time, and we do not track you across other apps or websites. This page itself has no cookies, forms or analytics.
How we use information
- to run the Service, save your progress and sync it across your devices
- to create your account, keep it secure and sign you in
- to provide paid features and confirm your subscription
- to keep the Service safe, fast and reliable, and to prevent abuse
- to answer your messages and requests
- to meet our legal obligations
We do not use your information for advertising, and we do not sell it.
Legal bases (EEA, UK and similar regions)
Where the law requires a legal basis for using your information, we rely on: performing our contract with you (running your account and subscription), our legitimate interests (security, reliability and improving the Service), your consent where we ask for it (for example when you sign in with Apple), and legal obligations.
Who we share it with
- Service providers that host our database, servers and backups and process information for us, such as Supabase and Amazon Web Services. They may use it only to provide those services to us.
- Apple and Google, when you sign in with Apple or subscribe through the App Store or Google Play.
- Other users, but only your display name and only where a feature lets users see each other.
- Authorities or advisers, when the law requires it or to protect people’s rights and safety.
- A buyer or successor, if Chainiac is ever sold or merged. This policy would keep applying to your information unless you are told otherwise.
We do not sell personal information, and we do not share it for cross-context behavioural advertising.
How long we keep it
Information on your device stays until you clear it, sign out and clear the app’s data, or uninstall the app. Account details and results are kept while your account is open. When you ask us to delete your account we remove them, except where we must keep something by law. Copies in backups are overwritten on the normal backup cycle.
Your choices and rights
- Sign out at any time from within the app.
- Ask us to access, correct, export or delete the information we hold about you by emailing support@chainiac.example from the address on your account. We will reply within 30 days.
- If you are in the EEA, the UK or Switzerland you can also object to or ask us to restrict some uses of your information, and you can complain to your local data-protection authority.
- If you live in California or another US state with a privacy law, you have the right to know what we hold, to have it deleted or corrected, and not to be treated differently for using those rights. We do not sell or share your information as those laws define it.
Children
The Service is not directed to children under 13 (or the higher age set by law where you live), and we do not knowingly collect personal information from them. If you think a child has given us personal information, email us and we will delete it.
Security
We encrypt information in transit, restrict access to our servers and databases, and limit how fast a single client can send requests. No system is perfectly secure, so please use a password for your account that you do not use anywhere else.
International transfers
Our providers may process information in countries other than yours, including the United States. Where the law requires it we use safeguards such as standard contractual clauses.
Changes to this policy
If we change this policy we will update the date at the top and, for material changes, tell you before they take effect.
