Privacy Policy

1. What we collect

Statesis is built to keep your research data on your device. We collect the minimum needed to run the app's subscription and support features:

• Subscription entitlement status (Free / Pro), managed by RevenueCat so the app knows what you've paid for. RevenueCat caches this on-device so the app keeps working offline.
• Purchase and billing information, handled entirely by Apple's StoreKit (App Store purchases). We never see or store your card details ourselves.
• Crash reports and performance data via Sentry, if you opt in. This is anonymised technical data (what crashed, not what was in your dataset).

2. Your research data stays on your device

The datasets you import, the analyses you run, and the output you generate are processed locally by the app's built-in statistics engine. We do not upload your datasets to a server, and we do not have access to your research data. iCloud sync of your saved projects (Pro) uses Apple's iCloud infrastructure and your own iCloud account, not a Statesis-operated server.

3. Third-party services we use

• RevenueCat: subscription entitlement management across the App Store.
• Apple StoreKit: in-app purchase processing.
• Sentry: crash and performance monitoring, opt-in.

Each of these processes only the data described above, needed to provide that specific feature.

4. Your rights

Because Statesis keeps your research data on your device, most of what a data protection law gives you a right to access, correct, or delete is already fully in your control locally — there is no copy on our servers to request. The rights below apply to the limited account and billing data described in Section 1.

If you are in the UK or EU (UK GDPR / EU GDPR): you have the right to access, correct, or erase the personal data we hold about you, to restrict or object to its processing, and to receive a copy of it in a portable format. You also have the right to lodge a complaint with your local data protection authority (in the UK, the Information Commissioner's Office). To exercise any of these rights, contact us via our contact page.

If you are a California resident (CCPA/CPRA): you have the right to know what personal information we have collected about you, to request its deletion, and to request correction of inaccurate information. We do not sell or share personal information, and we do not use it for cross-context behavioural advertising. Making one of these requests will not result in different treatment.

For any of the above, we may need to verify your identity (for example, by confirming the email address associated with a purchase) before acting on a request.

5. Changes to this policy

If this policy changes in a way that materially affects how your data is handled, we'll update the date at the top of this page and, where required, notify you in the app.

6. Contact

Statesis is operated by Nigel Douglass, based in the United Kingdom. Questions about this policy, or requests relating to the rights described above, can be sent via our contact page.
