AltersOne

Talk with your inner parts.

There is more than one voice inside you: the one that keeps watch, the one that plans, the one that is afraid, the one that dreams. AltersOne gives them a place to talk to each other. A native messaging app with yourself, built with total privacy from day one.

Coming soon on the App Store Privacy

What you do with it

  • Your parts, their roles

    Ten roles inspired by the Internal Family Systems model (IFS): Host, Protector, Exile, Firefighter, Manager, Proxy, Extinguisher, Little, Self and Ghost — or any word of your own. Give each participant a color, or a custom gradient with Premium.

  • One conversation, many voices

    Pick who is speaking with a single gesture, write, send: message bubbles switch sides based on the active point of view so each part reads from its own seat.

  • Stage directions and narration

    Capture what is happening internally with stage directions: group-level narration displayed in the center of the thread.

  • A journal of states of mind

    Every part can express how it feels at any moment. The Status tab shows at a glance who feels how, and preserves each participant’s mood history.

  • Built to last

    Archive conversations and participants to set them aside without losing anything; permanent deletion stays available, and every profile keeps its change history.

  • Private by design

    No account, no analytics, no ads, no tracking. Local storage encrypted by iOS and unreadable while your device is locked, with optional sync exclusively through your personal iCloud.

Privacy and Philosophy

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

  • Zero personal data collection.
  • No analytics, no telemetry, no third-party SDKs, no advertising.
  • No accounts or servers to register with.
  • Encrypted local database: on iPhone and iPad, iOS Data Protection keeps it unreadable while the device is locked; on Mac, FileVault protects it when turned on.
  • Optional private iCloud sync exclusively through your personal Apple ID (iCloud.eu.charlierconsulting.SelfTalk). Neither Charlier Consulting nor any intermediary has access to your synchronized data.

AltersOne is a space for writing and introspection. It is not a medical device and does not replace therapy.
