Local-First Architecture

Your data is yours. Transistor is designed so that the most sensitive information, your memory, your conversations, your files, lives on your device first and is never required to leave it.

What lives on your device

AI requests

When you send a message, Transistor sends that message along with relevant context from your memory to the AI provider you have chosen. Transistor does not see this request. It goes directly from your device to Anthropic, OpenAI, or whichever provider you use. Your relationship with that provider is governed by their privacy policy.

Sync

Sync is optional. When enabled, your memory and settings are encrypted on your device before being uploaded. Transistor stores only the encrypted blob and cannot read its contents. Sync uses end-to-end encryption with keys derived from your account credentials.

What Transistor does collect

Transistor collects anonymous, aggregated usage analytics to understand how the app is used at a broad level (for example, which features are most common). This data contains no personally identifiable information, no conversation content, and no memory. You can opt out from Settings.

Deleting your data

You can delete all local data from Settings at any time. If sync is enabled, you can also delete your cloud backup from your account settings. Deleting your Transistor account removes all synced data permanently.
