Third-Party AI Service — Data Sharing Disclosure

DayOne Fit uses OpenAI's API ("OpenAI", located at openai.com) as a third-party artificial intelligence service provider to power AI features within the app. This section explains exactly what data is shared, how it is used, and your rights.

What data is sent to OpenAI: When you use an AI-powered feature, the text you enter (prompts, questions, or inputs) and any context required to generate a relevant response are transmitted to OpenAI's servers for processing. No other personal data (such as your name, email, Apple ID, location, photos, contacts, or payment information) is sent.
Purpose: Data is sent solely to generate AI responses for the specific feature you are using. It is not used for advertising, profiling, or any other purpose.
OpenAI's data handling: OpenAI does not use data submitted via its API to train or improve its models. API data may be retained by OpenAI for up to 30 days for trust and safety (abuse monitoring) purposes, after which it is deleted. For full details, see OpenAI's API data usage policy at openai.com/policies/api-data-usage-policies.
Your consent: Before any data is sent to OpenAI, the app displays a clear disclosure screen explaining what data will be shared. You must agree before AI features become active. You may review this disclosure at any time in the app's Settings.
Your control: AI features are entirely optional. If you choose not to consent, the app continues to function without AI capabilities. No data is transmitted to OpenAI until you actively use an AI feature after providing consent.
Revoking consent: You can revoke your AI data consent at any time by going to Settings → AI Data Usage → "Revoke AI Data Consent." Once revoked, no further data will be sent to OpenAI until you consent again. AI features will be disabled until you re-consent.
Security: All data transmitted to OpenAI is encrypted using industry-standard HTTPS/TLS encryption.

Data Storage and Security

Local Storage: Your data is stored locally on your device.
No Cloud Backup by Us: We do not maintain copies of your data on our servers.
Encryption: All data transmitted uses industry-standard encryption (HTTPS/TLS).

Your Rights

Delete: Remove your data at any time
Cancel: Cancel subscription through App Store

Optional advertising measurement

Some Hatching Point apps include Meta's SDK in a disabled state. It initializes only when measurement is enabled for that app and you authorize tracking through Apple's App Tracking Transparency prompt. When enabled, device identifiers, product interactions, and verified purchase event details such as value and currency may be shared with Meta for advertising measurement and analytics. Payment-card details are never shared. You can deny the request or revoke permission later in iOS Settings.
