When you use the App we automatically collect certain technical and usage data:

You can disable cookies in your browser; the App will continue to function, but certain website features may be limited.
2.4 Information from third-party sources
If you interact with third-party accounts (e.g. sign in with Apple or link a social-media profile) we may receive a limited set of personal data such as an anonymized user identifier or hashed email address, subject to the permissions you grant to that third party.

Key third-party processors currently include:
Apple (App Store / CloudKit), Google (Firebase Analytics, Crashlytics), Appsflyer (mobile attribution), Amplitude (event analytics), RevenueCat (subscription backend), Facebook Audience Network / Meta Ads, and Adjust. Links to their privacy notices are available inside the App under Settings > Privacy & Legal.
6. INTERNATIONAL DATA TRANSFERS
Your data may be processed on servers located in the United States, the European Economic Area, or other jurisdictions where our service providers operate. We rely on adequacy decisions or Standard Contractual Clauses approved by the European Commission to safeguard cross-border transfers.

• Request deletion (“right to be forgotten”).
• Object to or restrict certain processing.

9. CHILDREN’S PRIVACY
The App is not intended for children under 13 (or the minimum age required by local law). We do not knowingly collect personal data from children. If we become aware that a child has provided personal information, we will delete it promptly. Parents who believe their child has submitted data may contact us at care.butlerai@outlool.com.
10. SECURITY
We employ administrative, technical, and physical safeguards designed to protect your data against unauthorised access, disclosure, alteration, and destruction. Measures include data encryption in transit (TLS 1.2+), encryption at rest, least-privilege access controls, routine security audits, and staff training. No system is 100 % secure, but we continuously evolve our defences.
11. OPT-OUT OPTIONS
• Analytics – toggle “Share Usage Data” off in Settings.
• Personalised ads – on iOS go to Settings > Privacy & Security > Apple Advertising and turn off “Personalised Ads”; alternatively, go to Settings > Privacy & Security > Tracking and disable Butler Pro or all apps.
• Email marketing – use the “unsubscribe” link or the in-app switch under Settings > Notifications.
• Push notifications – disable in iOS Settings > Notifications.
• Data collection in general – uninstalling the App stops all future collection on that device.
12. CHANGES TO THIS POLICY
We may update this Policy from time to time (e.g., to reflect new features, regulatory changes, or feedback). When we make material changes we will:
• Post the revised Policy in-app under Settings > Privacy policy;
• Send a push notification or email, or display a prominent banner before the change takes effect.
Continued use of the Service after the effective date constitutes acceptance of the updated Policy.
