AltersOne — Privacy Policy

Last updated: 14 September 2026.

This privacy policy applies specifically to the AltersOne application for iOS, iPadOS and macOS, developed by Charlier Consulting.

Overview

AltersOne is designed from the ground up to protect your privacy. Writing and exploring your inner dialogue requires complete trust:

• AltersOne collects no personal data.
• It contains no analytics, no tracking, no advertising and no third-party SDKs.
• We do not run any user accounts or private servers for AltersOne.

Data storage on your device

All your conversations, participants (alters), groups, mood journal entries, history and application settings are stored locally on your device in a database managed by Apple's Core Data framework. On iPhone and iPad, this database uses the strictest iOS file protection class (Data Protection "Complete"): it is encrypted with a key tied to your device passcode and cannot be read while your device is locked. On Mac, it is protected by FileVault disk encryption when FileVault is turned on.

Nothing leaves your device unless you explicitly enable private iCloud synchronization.

Optional iCloud synchronization

If you choose to enable iCloud synchronization in AltersOne settings:

• Your data is synchronized across your devices using Apple's CloudKit framework and your personal Apple ID account.
• Data is stored in your private iCloud container (iCloud.eu.charlierconsulting.SelfTalk).
• Transmission and storage are encrypted by Apple.
• If you enable Advanced Data Protection for iCloud, this data is end-to-end encrypted.
• Neither Charlier Consulting nor any intermediary has access to your synchronized data.
• You can disable iCloud synchronization at any time in the app settings, or delete your synchronized data through your iOS/macOS iCloud storage management.

Subscriptions and in-app purchases

AltersOne Premium features are offered through auto-renewable subscriptions and one-time purchases:

• All transactions and billing are handled directly by Apple via StoreKit 2 and your App Store account.
• Charlier Consulting never receives, processes or stores your credit card details, billing address or financial identifiers.
• Apple only provides anonymous receipt validation and transaction entitlements to unlock Premium features on your devices.

Support and communication

If you contact us for support (by e-mail at support@charlierconsulting.eu or through our contact form):

• Your name, e-mail address and the details of your inquiry are used solely to answer your questions.
• We do not share your contact details with any third party.
• Support communications are retained only as long as necessary to assist you, and are then deleted.
