Nutshell privacy policy

Effective October 29, 2026
Iteration18 Software Solutions Inc. (“Iteration 18”, “we”, “us”)

Nutshell is a personal life tracker: nested todos, calendar, food and calorie logging, health measures, and symptoms, stored offline-first and synced across your devices. This policy explains what information the app handles and how we treat it.

AI

We use AI tools to develop Nutshell. The app also has AI built in. When you dictate or type an entry for the assistant to interpret, that text is sent to a language-model provider (currently OpenAI) so it can be turned into a todo, meal, or measurement. Nothing is sent unless you use that feature. We do not use AI features for advertising.

Information the app uses

How we use it

We do not sell personal information. We do not use the app for advertising.

Where data is stored

A copy stays on your device. When sync is enabled, data is also stored with our hosting providers, currently Supabase.

Sharing

We share information only with infrastructure providers that process data on our instructions (currently Supabase for sync and Firebase for push notifications), with the language-model provider when you use the AI entry feature, and if required by law. Your data is not shown to other Nutshell users.

Retention

We keep account and synced todos while the account is active. You can delete items in the app. To request deletion of an account, email steve@iteration18.com.

Children

Nutshell is not directed at children under 13. We do not knowingly collect information from children.
