MindBlink privacy policy

Last updated June 2026

The short version

MindBlink is a second brain: you speak, it remembers. Your thoughts are yours. We don't sell data, we don't run ads, there are no third-party analytics or tracking SDKs in the app — at all. Your voice is never stored or transmitted, anywhere.

What we store

• Your thoughts, as text. Transcription happens on your device. Only the text reaches our servers. Audio is never recorded to disk, never uploaded — this is an architectural property of the app, not a policy promise.
• What the brain derives: entities, memories, your profile, briefings, letters — all generated from your own words and deletable with them.
• Account basics:a Sign in with Apple identifier and (if you share it) your email, which may be Apple's private relay address. Timezone and notification tokens for briefings.

Who processes it

Your text is processed by these subprocessors, all in the United States: Vercel (hosting), Neon (database, encrypted at rest), Anthropic and OpenAI (language-model inference and embeddings, via Vercel AI Gateway with zero data retention — no provider trains on or stores your thought content).

What we don't do

• No advertising, no data sales, no tracking across apps.
• No third-party analytics SDKs — usage counters are first-party rows in our own database.
• No human reads your thoughts except as required by law.

Export and deletion

Export everything (JSON) from Mind → Export everything. Delete your account from Mind → Delete account: every thought, memory, profile section, briefing, and letter — including search embeddings — is deleted immediately in one cascade. Database backups age out within about 7 days (the point-in-time-recovery window).
