Privacy policy

Effective date: March 30, 2026

Onset ("we," "our," or "the app") is operated by Last 1 Enterprises LLC. This policy describes how we handle your information when you use the Onset iOS application.

What data we collect

Onset collects only the data you explicitly provide through the app:

• Daily check-in responses (sleep quality, energy, soreness, and mood on a 1–10 scale; libido when relevant to your profile)
• Optional check-in fields for cycle-aware profiles (for example flow level, cravings, or bloating when you use those prompts)
• Protocol completion status (which items you marked as done)
• Your biological-sex profile and selected mode (e.g. Recovery, Performance, or Fertility for a male profile; Balance, Cycle awareness, or Fertility for a female profile)
• Your preferences (wake time, event timer lead time, notification settings)
• If you use cycle awareness: approximate cycle settings you enter (such as last period start, cycle length, and whether you track a menstrual cycle)

Where data is stored

Onset uses a mixed storage model:

• On-device storage (SwiftData): your routine data, check-ins, completions, and preferences remain on your device.
• Cloud processing (Supabase + AI providers): if you use cloud AI features (for example Daily AI Insight or AI protocol generation), selected request inputs are sent securely to our backend for processing and response generation.

Cloud AI requests may include your selected mode, biological-sex profile, non-identifying daily context, optional check-in summaries, and optional health context you explicitly enabled.

What we do not collect

• We do not require a traditional account signup flow with username/password
• We do not collect location data
• We do not sell your personal data
• We do not collect device identifiers for advertising purposes
• We do not use third-party ad tracking SDKs

Third-party services

Onset uses third-party infrastructure providers to operate core functionality:

• RevenueCat for subscription entitlement management. revenuecat.com/privacy
• Supabase for backend APIs, storage of cloud AI outputs, and operational metrics.
• Anthropic (or other configured model providers) for AI text generation used in cloud AI features.

Payments are handled by Apple. We do not receive raw payment card details.

Analytics and telemetry

Onset records limited product telemetry events to improve reliability and product quality. These events include functional app events (for example paywall shown, onboarding completed, insight refresh tapped) and do not include ad-targeting identifiers.

We use this telemetry for operational monitoring, conversion funnel health, and feature reliability checks.

Data sharing

We do not sell or rent your personal data. We share data only with service providers needed to run the app (for example hosting, subscription infrastructure, and AI generation providers) under contractual controls.

Data retention and deletion

On-device data is under your control and can be removed by deleting the app. Cloud records used for AI operations and telemetry are retained only as needed for product operation, abuse prevention, and reliability analysis.

If you want data deletion help, contact privacy@theonset.app.

Children's privacy

Onset is not intended for use by individuals under the age of 17. We do not knowingly collect data from minors.

Changes to this policy

We may update this policy as we add features (such as cloud sync or Apple Health integration). When we do, we will update the effective date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
